Quicksilver Lite in Whonix / creating a Mixmin nym

mirimir posted a guide to wilderssecurity.com forum, see Installing Quicksilver Lite in Whonix and creating a Mixmin nym. If you need help, try asking in that forum thread.

Please note that Whonix developers cannot answer support requests related to Quicksilver. This possibility has just been pointed out and wasn't tested in practice. It is a whole different thing than Whonix and very technical, difficult with many stumble points. Please look for another way, if you need support. Setting up Nym is not Whonix specific. Success stories, use cases, comments, improved documentation etc. however is welcome.

grsecurity

About grsecurity

Linux kernel is not a secure OS, Linus himself made it pretty clear that he doesn't think highly of the "security community". His threat model and a Tor User threat model don't have much in common. Good that Linux is open source and if we disagree with a policy or politics we can just patch or fork it... Grsecurity/PaX is the most comprehensive kernel patch providing much needed security hardening both for the kernel itself and for making userland protections more effective.

Sadly Debian does not ship a grsecurity kernel. That means either a packager/maintainer of Whonix needs to compile them EVERY TIME there is a security update to the kernel (which is pretty frequently) or the Whonix users themselves need to compile and update their kernels. This is undesirable because kernel compilation is not set and forget, you need a bit of knowledge, it takes a while, especially in a resource restricted VM and you need to keep updated about new releases via mailing lists or similar because your software updater doesn't automatically handle custom kernels (even emerge in hardened gentoo doesn't). All this would most likely only result in users running old, outdated kernel versions.

Furthermore, for Whonix-Gateway and the Identity/Location TCB grsecurity only addresses a subset of security risks: It can mitigate some kernel vulnerabilities (and we only really care about the networking stack which is pretty secure judging from its track record). Maybe some (memory corruption) vulnerabilities in apt-get and Tor that aren't already mitigated by the existing userland hardening done by Ubuntu. It can't protect against backdoors or security issues related to design, policy or yet unknown classes of exploits. We feel that these relatively small advantages outweigh the issues introduced by using a custom compiled kernel. We hope a binary distro will step forward and start using grsecurity. In that case we'll most likely switch Whonix-Gateway to that distro as soon as possible.

For Whonix-Workstation the benefits are even more doubtful. To be effective grsecurity needs to lock down some functions that are needed by Xorg, JIT compilers... but we need those to be working. To solve this we'd have to write a restrictive RBAC policy which is far from trivial. We think accepting that Whonix-Workstation will be exploitable and acting accordingly (using snapshots and rolling back to clean state) is the right approach for a desktop system.

If you disagree with this assessment or have any suggestions how to improve the current situation please let us know.

Experts only: There is also Hardened Gentoo based Whonix-Gateway. Outdated, needs maintainer. See Hardened Gentoo TG .

Updates:

• There's Alpine Linux, where Tor is in testing. Package Request: Tor.</ref>
• Arch Linux offers a grsecurity kernel.

Footnotes:

Installation

Try these instructions: grsecurity

Or...

Advanced users only!
These instructions are not in a state yet where they are easily usable by anyone.

Install genmkfile. See instructions for apparmor-profile-torbrowser but replace apparmor-profile-torbrowser with genmkfile.

Install grsecurity-installer. See instructions for apparmor-profile-torbrowser but replace apparmor-profile-torbrowser with grsecurity-installer.

To speed up compilation, you might want to assign additional CPU cores and more RAM to your virtual machine.

Run grsecurity-installer to download kernel sources, grsecurity patch, compile and install the grsecurity kernel.

[select code]

sudo bash -x grsecurity-installer

sudo bash -x grsecurity-installer

During make menuconfig you need to enable grsecurity.

TorChat

HowTo

Installation

EXPERIMENTAL
Experimental in that it is difficult to install. Only use it in case you trust TorChat. There shouldn't be any anonymity leaks and it should be as safe as other hidden services in general and in Whonix.

Learn about Hidden Services in Whonix first and learn how to set up the hidden webserver. This will ease following this guide.

On Whonix-Gateway

Step 1: open /etc/tor/torrc

Open /etc/tor/torrc.

If you are using Qubes-Whonix, complete the following steps.

Qubes App Launcher (blue/grey "Q") -> Whonix-Gateway ProxyVM (commonly named sys-whonix) -> Tor User Config (Torrc)

If you are using a graphical Whonix-Gateway, complete the following steps.

Start Menu -> Applications -> Settings -> /etc/tor/torrc

If you are using a terminal-only Whonix-Gateway, complete the following steps.

[select code]

sudo nano /etc/tor/torrc

sudo nano /etc/tor/torrc

Step 2: edit /etc/tor/torrc

(all Whonix platforms)

Once inside /etc/tor/torrc, scroll all the way to the bottom, and copy-paste the following text:

Qubes-Whonix:

The IP-of-Qubes-Whonix-Workstation-AppVM needs to be replaced with the actual IP address. To find out the IP address of the Qubes-Whonix-Workstation AppVM, the following command can be run within the Qubes-Whonix-Workstation AppVM: qubesdb-read /qubes-ip

[select code]

HiddenServiceDir /var/lib/tor/torchat/
HiddenServicePort 11009 IP-of-Qubes-Whonix-Workstation-AppVM:11009

HiddenServiceDir /var/lib/tor/torchat/ HiddenServicePort 11009 IP-of-Qubes-Whonix-Workstation-AppVM:11009

Non-Qubes-Whonix:

[select code]

HiddenServiceDir /var/lib/tor/torchat/
HiddenServicePort 11009 10.152.152.11:11009

HiddenServiceDir /var/lib/tor/torchat/ HiddenServicePort 11009 10.152.152.11:11009

(all Whonix platforms)

Save.

Step 3: make changes to /etc/tor/torrc take effect

Reload Tor.

After editing /etc/tor/torrc, Tor must be reloaded for changes take effect.

Note: If Tor does not connect after completing all these steps, then a user mistake is the most likely explanation. Recheck /etc/tor/torrc and repeat the steps outlined in the sections above. If Tor then connects successfully, all the necessary changes have been made.

If you are using Qubes-Whonix, complete the following steps.

Qubes App Launcher (blue/grey "Q") -> Whonix-Gateway ProxyVM (commonly named 'sys-whonix') -> Reload Tor

If you are using a graphical Whonix-Gateway, complete the following steps.

Start Menu -> Applications -> Settings -> Reload Tor

If you are using a terminal-only Whonix-Gateway, press on Expand on the right.

Complete the following steps.

Reload Tor.

[select code]

sudo service tor@default reload

sudo service tor@default reload

Check Tor's daemon status.

[select code]

sudo service tor@default status

sudo service tor@default status

It should include a a message saying.

Active: active (running) since ...

In case of issues, try the following debugging steps.

Check Tor's config.

[select code]

sudo -u debian-tor tor --verify-config

sudo -u debian-tor tor --verify-config

The output should be similar to the following.

Sep 17 17:40:41.416 [notice] Read configuration file "/etc/tor/torrc".
Configuration was valid

Step 4: get your onion hostname

Find out your .onion hostname.

[select code]

sudo cat /var/lib/tor/torchat/hostname

sudo cat /var/lib/tor/torchat/hostname

Step 5: backup your Tor hidden service private key

Reminder: Always backup the hidden service key. This is necessary in order to restore it on another machine, on a newer Whonix-Gateway, after HDD/SSD failure, etc. Follow the instructions below to find its location; root permission is required to access it.

/var/lib/tor/torchat/private_key

Qubes-Whonix

Use the usual Qubes tools. The following example shows how to copy the /var/lib/tor/torchat/private_key from the sys-whonix VM to the vault VM (which should be started beforehand) using qvm-copy-to-vm.

[select code]

sudo qvm-copy-to-vm vault /var/lib/tor/torchat/private_key

sudo qvm-copy-to-vm vault /var/lib/tor/torchat/private_key

The above step copies the Tor hidden service private key file to the QubesIncoming folder of the vault VM.

[select code]

/home/user/QubesIncoming/sys-whonix/private_key

/home/user/QubesIncoming/sys-whonix/private_key

Consider moving the file from the QubesIncoming folder to another preferred location.

Qubes VM Manager can be used to conveniently backup the vault and/or other VMs. Please refer to the Qubes backups documentation for necessary steps to accomplish that.

Non-Qubes-Whonix

TODO document
Also see: File Transfer.

On Whonix-Workstation

Step 1: Install TorChat

Update your package lists.

[select code]

sudo apt-get update

sudo apt-get update

Install TorChat.

[select code]

sudo apt-get install torchat python-socksipy

sudo apt-get install torchat python-socksipy

Step 2: Configure TorChat

Open the torchat.ini which is in the hidden folder /home/user/.torchat/torchat.ini. The folder ~/.torchat/Tor can be ignored.

[select code]

kwrite /home/user/.torchat/torchat.ini

kwrite /home/user/.torchat/torchat.ini

Look for the following line.

own_hostname = <your onion hostname without the .onion ending>

Replace it with your onion hostname. For example if your onion hostname is idnxcnkne4qt76tg.onion replace it enter idnxcnkne4qt76tg, so it looks like this:

own_hostname = idnxcnkne4qt76tg

Save.

Step 3: Qubers users only

Qubes-Whonix users who require an additional firewall exception, please press Expand on the right.
Note: Non-Qubes-Whonix users can skip this step.

Open firewall port access for the application between Whonix-Gateway and Whonix-Workstation.

[select code]

sudo iptables -I INPUT 5 -p tcp --dport 11009 -m conntrack --ctstate NEW -j ACCEPT

sudo iptables -I INPUT 5 -p tcp --dport 11009 -m conntrack --ctstate NEW -j ACCEPT

Unless setting up a web server, change the port number from 11009 to whatever the application requires.

To make the firewall rule persistent, add the rule to the rc.local file and make it executable.

Open /rw/config/rc.local.

[select code]

kdesudo kwrite /rw/config/rc.local

kdesudo kwrite /rw/config/rc.local

Add the following in the rc.local file.

[select code]

#!/bin/sh
sudo iptables -I INPUT 5 -p tcp --dport 11009 -m conntrack --ctstate NEW -j ACCEPT

#!/bin/sh sudo iptables -I INPUT 5 -p tcp --dport 11009 -m conntrack --ctstate NEW -j ACCEPT

Make the rc.local file executable.

[select code]

sudo chmod +x /rw/config/rc.local

sudo chmod +x /rw/config/rc.local

Step 4: Final Notes

Done.

Note, that it may take up to 30 minutes (or so?) until a fresh .onion domain gets reachable.

Starting

Qubes-Whonix:
Qubes App Launcher (blue/grey "Q") -> Whonix-Workstation AppVM (commonly named whonix) -> TorChat Instant Messenger

Non-Qubes-Whonix:
Start menu -> Applications -> Internet -> TorChat Instant Messenger

Uninstall

If you want to remove it...

On Whonix-Workstation.

[select code]

sudo apt-get remove torchat

sudo apt-get remove torchat

On Whonix-Gateway.

Open /etc/tor/torrc.

If you are using Qubes-Whonix, complete the following steps.

Qubes App Launcher (blue/grey "Q") -> Whonix-Gateway ProxyVM (commonly named sys-whonix) -> Tor User Config (Torrc)

If you are using a graphical Whonix-Gateway, complete the following steps.

Start Menu -> Applications -> Settings -> /etc/tor/torrc

If you are using a terminal-only Whonix-Gateway, complete the following steps.

[select code]

sudo nano /etc/tor/torrc

sudo nano /etc/tor/torrc

And undo the changes in /etc/tor/torrc on Whonix-Gateway.

Reload Tor.

After editing /etc/tor/torrc, Tor must be reloaded for changes take effect.

Note: If Tor does not connect after completing all these steps, then a user mistake is the most likely explanation. Recheck /etc/tor/torrc and repeat the steps outlined in the sections above. If Tor then connects successfully, all the necessary changes have been made.

If you are using Qubes-Whonix, complete the following steps.

Qubes App Launcher (blue/grey "Q") -> Whonix-Gateway ProxyVM (commonly named 'sys-whonix') -> Reload Tor

If you are using a graphical Whonix-Gateway, complete the following steps.

Start Menu -> Applications -> Settings -> Reload Tor

If you are using a terminal-only Whonix-Gateway, press on Expand on the right.

Complete the following steps.

Reload Tor.

[select code]

sudo service tor@default reload

sudo service tor@default reload

Check Tor's daemon status.

[select code]

sudo service tor@default status

sudo service tor@default status

It should include a a message saying.

Active: active (running) since ...

In case of issues, try the following debugging steps.

Check Tor's config.

[select code]

sudo -u debian-tor tor --verify-config

sudo -u debian-tor tor --verify-config

The output should be similar to the following.

Sep 17 17:40:41.416 [notice] Read configuration file "/etc/tor/torrc".
Configuration was valid

Debugging

In case it won't work for you.

Test if Tor is reachable on 10.152.152.10:9119.

[select code]

/usr/bin/wget.anondist-orig 10.152.152.10:9119

/usr/bin/wget.anondist-orig 10.152.152.10:9119

If it says.

--2013-02-13 13:49:47--  http://10.152.152.10:9119/
Connecting to 10.152.152.10:9119... connected.
HTTP request sent, awaiting response... 501 Tor is not an HTTP Proxy
2013-02-13 13:49:47 ERROR 501: Tor is not an HTTP Proxy.

It means, it is fine and the port is reachable.

Run torchat in a Terminal.

[select code]

torchat

torchat

The following output is an example, how it looks when everything is fine.

~ $ torchat

(0) [tc_client,2083,startPortableTor] very strange: portable tor started but hostname could not be read
(0) [tc_client,2084,startPortableTor] will use section [tor] and not [tor_portable]

If you are using Multiple Whonix-Workstations, where the Workstation has another IP than 10.152.152.11 you must edit the following line in torchat.ini.

listen_interface = 10.152.152.11

Did the hidden webserver example from the Hidden Services page work for you? Try that first.

You also could try using the TorChat source package, which is still documented on the Deprecated page.

Technical Design

The Dev/anon-ws-disable-stacked-tor package prevents Tor over Tor.

OnionCat

Introduction

• [[<tvar|173>OnionCat|</> OnionCat, GarliCat: Tunnel TCP, UDP, ICMP or any other protocol through Tor or I2P; IPv6, VPN-like, TAP/TUN tunneling device]]

Introduction to OnionCat:

• torproject wiki about OnionCat (w) (onion)
• cypherpunk.at/onioncat (w)
• cryptoanarchy.org about OnionCat (webarchive; webcitation)

Status

• OnionCat (Tor) will work with Whonix. (Tested.)
• GarliCat (I2P) might partially work with Whonix. (Untested.)

Over Tor

OnionCat transports any protocol between endpoints inside the Tor network. All involved peers need to run OnionCat. It gives IPv6 addresses to Onion Services, making many applications possible.

IPv6 is currently disabled on Whonix-Gateway, because Tor doesn't support IPv6 yet (except for bridges), and because no one developed more than rudimentary IPv6 firewall rules for Whonix-Gateway yet. Whonix-Gateway's firewall blocks all IPv6 traffic including local traffic by default. Anyway, that will not be an issue. IPv6 on Whonix-Workstation, where OnionCat will be running, is enabled. Since only OnionCat's underlying operating system requires IPv6, but not the Tor process there will be no problem. OnionCat on Whonix-Workstation will translate the IPv6 requests to IPv4 to the Tor process which is running on Whonix-Gateway. Therefore no IPv6 on Whonix-Gateway is required.

On your Whonix-Gateway.

If you want to read an introduction about hidden services and to learn about about hidden service security, see Hidden Services.

If you also want to run a hidden web server on the same .onion domain (nice for testing and learning Hidden Services basics), see Hidden Services.

Open /etc/tor/torrc.

If you are using Qubes-Whonix, complete the following steps.

Qubes App Launcher (blue/grey "Q") -> Whonix-Gateway ProxyVM (commonly named sys-whonix) -> Tor User Config (Torrc)

If you are using a graphical Whonix-Gateway, complete the following steps.

Start Menu -> Applications -> Settings -> /etc/tor/torrc

If you are using a terminal-only Whonix-Gateway, complete the following steps.

[select code]

sudo nano /etc/tor/torrc

sudo nano /etc/tor/torrc

Add.

[select code]

HiddenServiceDir /var/lib/tor/onioncat/ HiddenServicePort 8060 10.152.152.11:8060

Save.

Reload Tor.

After editing /etc/tor/torrc, Tor must be reloaded for changes take effect.

Note: If Tor does not connect after completing all these steps, then a user mistake is the most likely explanation. Recheck /etc/tor/torrc and repeat the steps outlined in the sections above. If Tor then connects successfully, all the necessary changes have been made.

On your Whonix-Workstation.

Update your package lists

[select code]

sudo apt-get update

sudo apt-get update

Install onioncat.

[select code]

sudo apt-get install onioncat

sudo apt-get install onioncat

Start onioncat. Replace address.onion with your actual hidden service url from above.

[select code]

sudo ocat address.onion -l 10.152.152.11:8060

sudo ocat address.onion -l 10.152.152.11:8060

As of onioncat r555 (only applies to Jessie onwards) onioncat starts in unidirection 'client' mode by default. To accept incoming connections -U must be used. Mutual authentication is also available in this newer version which is needed to ensure that the identities of all endpoints engaged in a transaction are verified.

[select code]

sudo ocat address.onion -U -l 10.152.152.11:8060

sudo ocat address.onion -U -l 10.152.152.11:8060

Alternatively, if starting onioncat in 'client' mode run:

[select code]

sudo ocat -R

sudo ocat -R

At least one node has to run as a 'server' with a Hidden service configured for contact to occur.

To enumerate your onioncat IPv6 address run:

[select code]

sudo ocat -i address.onion

sudo ocat -i address.onion

Notes

Security

There are two possible ways to authenticate and control who is allowed to connect to you Onioncat instance and the applications running on top of it.

1. The simpler and more robust approach is to setup Tor to perform authentication of clients connecting to your Hidden Service. If they do not possess a certain randomly generated cryptographic secret, they cannot connect to your Hidden Service.

For information on how to do this see Hidden Services#Hidden Service Authentication.

2. The second approach does this process at the higher level through delegating authentication to Onioncat.

For official documentation on security read the reference at the end of this sentence.

Onioncat Authentication Notes and Definitions:

• Bi-directional mode is what was used for OC since the beginning. That means that one established circuit (TCP session through Tor) is being used to send AND transmit packets. Thus, it is called bi-directional.

• Uni-directional mode means that there are two separate circuits: one for sending and one for receiving.

So what's the implications:
Circuits are established through Tor and are identified and authenticated by the network through the onion hostname (= OC IPv6 address). But this authentication is just one-ended. That means that the client (the one initiating the circuit) can authenticate the server but the server can't authenticate the client. As a consequence the client could spoof its IP address. In Tor/OnionCat context, IP spoofing means to use any IPv6 address but not the one which is associated to the onion ID (that's actually what -R does). Although this is technically no problem there's a security risk which could be that someone takes over the IPv6 address from someone else and could thereby attract (steal) packets. The risk is still very low.

Uni-directional mode addresses exactly that problem. It forces the server to not reuse an incoming connection but establish a new circuit to the supposed client. Thus spoofing is defeated because it requires for the client to own the private key as well.

Uni-directional mode is on by default since revision 556, but this change may be subject to change in future releases.

Uni-directional mode and -R (i.e. starting onioncat in 'client' mode) are incompatible! That means an OnionCat using -R will not be able to communicate with an OnionCat in uni-directional mode.

OnionCats with -R can only talk to bi-directional OnionCats having -U set as noted above.

Tunneling IPv4

Many programs do not support IPv6 and so to use IPv4 with Onioncat, IPv4 will need to be tunneled over IPv6. This option is preferred to Onioncat's native IPv4 forwarding designated by the -4 parameter, which is deprecated and could not have guaranteed the authenticity of the communicating endpoints as the tunneling method can.

Most operating systems should support IP-IP6 tunneling. IPv6 supports encapsulation of IPv4 or IPv6, hence, tunneling is not a big deal. An IP-IP6 tunnel is a point-to-point tunnel between two IPv6 nodes. The tunnel endpoints are virtual network interfaces. IP addresses are assigned to them and routing has to be set up as usual (as if those interfaces where ethernets). Before configuring a tunnel you need to know the two IPv6 addresses of the IPv6 nodes. Those will be the IPv6 OnionCat addresses. There are a few steps necessary on Linux. First insert the IPv6 tunneling kernel module, then setup the tunnel interface by connecting it to the two IPv6 addresses. Next configure the IPv4 addresses to the tunnel endpoints, bring them up and add the necessary routes (... and don't forget to update your firewall rules - but this is not needed with Whonix Workstation's default settings).

[select code]

sudo su
modprobe ip6_tunnel
ip -6 tunnel add iptun0 mode ipip6 local fd87:d87e:eb43:1f53:c75:3b27:7adc:c9a5 remote fd87:d87e:eb43:8733:3338:21f6:a2b8:eebf
ifconfig iptun0 192.168.100.1 up
route add -net 192.168.100.0/24 dev iptun0

sudo su modprobe ip6_tunnel ip -6 tunnel add iptun0 mode ipip6 local fd87:d87e:eb43:1f53:c75:3b27:7adc:c9a5 remote fd87:d87e:eb43:8733:3338:21f6:a2b8:eebf ifconfig iptun0 192.168.100.1 up route add -net 192.168.100.0/24 dev iptun0

On the other end do the same thing except that you have to swap the two IPv6 addresses and use another IP address on the tunnel endpoint, e.g. 192.168.100.2. If Tor, OnionCat, and the tunnel is up on both ends you should be able to ping the remote end.

Useful Commands

• Check connectivity between endpoints using ping:

[select code]

ping6 onioncat-address

ping6 onioncat-address

• Replies should come immediately if everything is working.

• To derive the OnionCat IPv6 address from your Hidden Service address run:

[select code]

ocat -i onion.address

ocat -i onion.address

• Running ifconfig can show helpful information on active network interfaces:

[select code]

sudo ifconfig

sudo ifconfig

Debugging

On your Whonix-Workstation.

To terminate onionat you could use.

[select code]

sudo kill -sigint $(pgrep ocat)

sudo kill -sigint $(pgrep ocat)

Miscellaneous

To make Onioncat to autostart with the system using the parameters listed above. editing its configuration file:

[select code]

sudo nano /etc/default/onioncat

sudo nano /etc/default/onioncat

Enable the autostart comment by removing '#':

ENABLED=yes

Add your settings:

DAEMON_OPTS="Paramters go here"

Over I2P

GarliCat over I2P might only work, if you use ip2 over Tor.

There was the idea to create an I2PBOX, but it never came to live due to lack of community interest, which means GarliCat directly over I2P will not be supported by Whonix.

As soon as I2P over Tor is working in Whonix-Workstation, you can probably follow the instructions on cryptoanarchy.org (webarchive; webcitation) without modifications.

General Debugging Hints

• There at multiple sources for issues, you might stumble upon.
• Therefore it is recommended, before you try using OnionCat with Whonix, if that doesn't endanger you, try first to successfully test OnionCat without Whonix.
• As soon as you learnt that, it eliminated one source for possible issues (OnionCat) and can start learning how to use it with Whonix (which might introduce new issues, but enhanced security will be your reward).
• You also have to learn first, how to use hidden services with Whonix, see hosting hidden services for reference.

Server Settings Tab, set the IMAP address to: imap.<address>.onion

Outgoing Server (SMTP) Tab, Edit: smtp.<address>.onion

The service providers may or may not enable TLS/STARTTLS connection security for their Onion domain since it is redundant. Its best to leave turned on by default and only disable it if problems arise.

Leave your Default Identity with the clearnet domain to avoid confusing recipients when replying to you.

Pidgin

For instant messaging in Whonix you can install the Pidgin Instant Messenger. It is a multi-protocol client, so you could run MSN, ICQ, IRC, AIM, XMPP/Jabber and many other protocols at the same time, even with several instances of the same protocol.

All of these chat systems are unsafe if not used together with OTR. Even when used with OTR, expect to be exposing your social graph. Privacy hackers isolate parts of the social graph by running several accounts for groups of people on each popular server, thus avoiding the insecure XMPP federation (adding people on servers that is not your own).

For more detailed documentation refer to the official Pidgin user guide.

You can install it using Start menu -> Applications -> System -> Terminal.

[select code]

sudo apt-get update

sudo apt-get update

[select code]

sudo apt-get install pidgin

sudo apt-get install pidgin

There is also a Torchat plugin available for pidgin official libpurple-torchat pidgin plugin, which could be implemented to allow p2p encrypted end-to-end communications although there is no known documentation on getting this done specifically in Whonix. It works seamless on standard pidgin/linux distro's with tor, the code is over a year without any changes/updates, hopefully because it simply works without any need for changes.

Some protocols that are problematic in context of privacy/anonymity are disabled by default.

To get a list of those, you could run.

[select code]

sudo dpkg-divert --list

sudo dpkg-divert --list

To re-enable all of them, you could run.

[select code]

sudo /var/lib/dpkg/info/pidgin-improved-privacy.prerm remove

sudo /var/lib/dpkg/info/pidgin-improved-privacy.prerm remove

After a restart of Pidgin, the protocols will be available.

OTR encryption

Of course the issue of end-to-end encryption arises again. As we mentioned earlier, we have Off-the-record messaging (commonly called OTR) for instant messaging, and Pidgin and many other instant messengers have support for that. There are several resources on how it works and how to use it on their web site. Basically all you need to do is choose "Start private conversation" in the OTR menu and a key will be generated automatically if you do not have one already. After that OTR will establish a private conversation if the other end's instant messenger supports it.

If you didn't authenticate your partner with something like a shared secret there can be a man in the middle recording your chat, even if you are using the same server (the server or the TLS connection to the server may be corrupted).

OTR and other Pidgin plugins are enabled in the "Tools menu -> Plug-ins" section. Simply check the appropriate box for enabling any plugin you want, and possibly you might also want to configure it by pressing the "Configure Plug-in" button. When this is done for the OTR plugin a window that can be used to manage your keys will open. The use of OTR is recommended as many instant messaging protocols normally sends your messages in plaintext. Force your friends to migrate to clients with support for OTR!

NOTE: /me is not encrypted when used in a OTR private conversation! Also /msg in XMPP chatrooms is not – it goes through the chatroom server!

Read also those various other resources about OTR.

You can install it using Start menu -> Applications -> System -> Terminal.

Jitsi

Jacob Appelbaum (Tor researcher) recommends Jitsi (this applies if _not_ using Tor). It supports OTR encryption and ZRTP and is available in Debian Testing.

Jitsi supports push to talk.

Jitsi is the most feature-rich Free Software VoIP client. The team behind it is very innovative, constantly focusing on adding new functionality. It supports many protocols and advanced features like Multi-party video conferencing - in which someone's client will be running into server mode for that purpose because of latency management.

Its stability leaves more to be desired however. Alpha stage clients are available for Android.

Unfortunately it is not usable with Tor, because the Tor network does not support UDP and because Jitsi does not support TCP for audio/video at time of writing (April 2014).

TODO: write a guide on how to connect to a free public server, having a secure ZRTP encrypted conversation with someone using the same client (note: impossible as of April 2014 without revealing the ip numbers of the corresponding parties to both eavesdroppers and the server).

sflphone

Nathan Freitas (Tor Orbot developer) likes sflphone. Can be installed from Debian package sources.

It does not support OTR. You would have to keep that in mind and use another way to exchange encrypted text. This is not a reason, not to use it, if you are aware of that.

TODO: research, does sflphone support push to talk?

TODO: write a guide how to connect to a free public server, having a secure ZRTP encrypted conversation with someone using the same client.

OnionPhone

OnionPhone is the successor to TOR Fone, improving the ciphers used among other problems. Repo here

The main improvement is that OnionPhone can now be used as a VoIP plugin that integrates it with with TorChat, using the Tor network to protect and anonymize your communication in this mode. It is also the only mode that makes sense in terns of usability because otherwise its a command line utility.

OnionPhone works on Linux and Windows, with Android support planned.

Other modes of operation include using the Tor network as a decentralized and secure alternative for SIP signalling. The call streams are then initiated directly using either TCP or UDP (for NAT traversal). Note that metadata is not concealed in that mode.

It can be run standalone with direct connections with OnionCat.

TODO: Encourage Debian Packaging TODO: Build, test and document usage instructions with TorChat

linphone

Introduction

Linphone is one of the most feature-rich Free Software clients available, second only to Jitsi in that respect, but second to none is stability and performance from testing. It can also support conferencing (audio only as of 2014). Additionally it has fully developed clients for all desktop and mobile operating systems.

Should an Android port of Onioncat ever become a reality by the Guardian Project, Linphone can be used for anonymous VoIP between all combinations of device form factors. There is headway on that front.

Setup with Whonix

Technically, only one member of the chat party needs to configure a Tor Hidden Service (be a callee). Others can run Onioncat in 'client' only mode (be ca caller).

Bidirectional communication can only be established after the client party (caller) connects to the one running a hidden service 'server' mode (callee), because the latter can accept incoming connections while the former cannot.

	callee	caller
Can make outgoing calls	Yes	Yes
Can initially receive incoming calls	Yes	No
Needs to host a Tor hidden service	Yes	No
Difficulty setup	medium	easy

Setup as Both, Callee or Caller

You only have to read this, if you want to use linphone as both, callee or caller. As a caller, you can only make outgoing calls. As a callee (that includes ability of being a caller), you can make outgoing calls and receive incoming calls. Only one of both calling parters has to follow these instructions. However, it doesn't matter if both calling partners follow these following instructions. If you are interested, click on Expand on the right.

On your Whonix-Gateway.

If you want to read and introduction about hidden services and to learn about about hidden service security, see Hidden Services.

If you also want to run a hidden web server on the same .onion domain (nice for testing and learning Hidden Services basics), see Hidden Services.

Open your /etc/tor/torrc.

[select code]

sudo nano /etc/tor/torrc

sudo nano /etc/tor/torrc

Add.

HiddenServiceDir /var/lib/tor/linphone_service/
HiddenServicePort 64739 10.152.152.11 :64739

Reload Tor.

[select code]

sudo service tor reload

sudo service tor reload

Reminder: To get your hidden service url.

[select code]

sudo cat /var/lib/tor/linphone_service/hostname

sudo cat /var/lib/tor/linphone_service/hostname

Reminder: Backup your hidden service key, in case you want to be able to restore it, on another machine, on a newer Whonix-Gateway, after hdd failure, etc. You can find it here and need sudo to access it.

/var/lib/tor/linphone_service/private_key

On your Whonix-Workstation.

Update your package lists

[select code]

sudo apt-get update

sudo apt-get update

Install onioncat and linphone.

[select code]

sudo apt-get install onioncat linphone

sudo apt-get install onioncat linphone

Start onioncat. Replace address.onion with your actual hidden service url from above.

[select code]

sudo ocat address.onion -U -l 10.152.152.11 :64739

sudo ocat address.onion -U -l 10.152.152.11 :64739

As of onioncat r555 (only applies to Jessie onwards) onioncat starts in unidirection 'client' mode by default. To accept incoming connections -U must be used. Mutual authentication is also available in this newer version which is needed to ensure that the identities of all endpoints engaged in a transaction are verified.

Find out your onioncat IPv6 address.

[select code]

ip addr show dev tun0

ip addr show dev tun0

Open Linphone settings and select IPv6. Apply and restart Linphone.

Setup only as Caller

You only have to read this, if you want to use linphone caller only. As a caller, you can only make outgoing calls. Only one of both calling parters can follow these instructions. If both calling partners would follow these instructions, would not be able to call each other. If you are interested, click on Expand on the right.

On your Whonix-Workstation.

Update your package lists

[select code]

Calling

On your Whonix-Workstation.

At this point you should have exchanged IPv6 addresses of the callee. To call someone put in the call box. You can keep user. Must use brackets. Replace onioncat IPv6 address with the actual IPv6 of your calling partner.

user@[onioncat ipv6 address]

Debugging

On your Whonix-Workstation.

To terminate onioncat you could use.

[select code]

sudo kill -sigint $(pgrep ocat)

sudo kill -sigint $(pgrep ocat)

Miscellaneous

To make Onioncat to autostart with the system using the parameters listed above. editing its configuration file:

[select code]

sudo nano /etc/default/onioncat

sudo nano /etc/default/onioncat

Enable the autostart comment by removing '#':

ENABLED=yes

Add your settings:

Development Ideas

OnionCat

OnionCat could be useful if tunneling UDP and/or ICMP tunneling over Tor should be required. It should be avoided if possible, because it add complexity to the setup. Does it introduce more latency because connection always goes from hidden service to hidden service?

OpenBazaar

OpenBazaar supports both TCP and UDP. The latter was added to aid those using it on the clearnet that had difficulties connecting from behind their routers. When using Tor you don't have to worry about that.

A community demo for OpenBazaar was done with Tor by hosting seed nodes as Hidden Services.

Hosting ANY Hidden Services

You can provide any server service, which relies on TCP, such as web servers, IRC servers, chat servers and so forth. UDP and IPv6 are not supported by the Tor network, but if required you could use OnionCat as a workaround.

OnionCat

See OnionCat.

Syncthing with OnionCat

Syncthing is a libre software solution for private file synchronization.

This section will cover file syncing with peers inside the Tor network.

TO-DO: Test Syncthing without OnionCat since SOCKS support was added recently.

1. Set up OnionCat on Whonix Gateway. All parties involved will need to configure a Hidden Service with OnionCat because syncing is bidirectional. Make sure you can successfully ping all OnionCat addresses before proceeding.

2. Before adding the repo, fetch the key and verify fingerprints. Always check the fingerprint for yourself. The output at the moment is:

pub  2048R/0xD26E6ED000654A3E 2014-12-29 Syncthing Release Management <release@syncthing.net>
      Key fingerprint = 37C8 4554 E7E0 A261 E4F7  6E1E D26E 6ED0 0065 4A3E

Download key with scurl to home folder.

[select code]

scurl -o syncthing-pubkey.asc https://syncthing.net/release-key.txt

scurl -o syncthing-pubkey.asc https://syncthing.net/release-key.txt

Check fingerprints/owners without importing anything.

[select code]

gpg --keyid-format long --with-fingerprint syncthing-pubkey.asc

gpg --keyid-format long --with-fingerprint syncthing-pubkey.asc

If it looks good import into trusted.gpg.d.

[select code]

gpg --no-default-keyring --keyring ./syncthing-pubkey.gpg --import syncthing-pubkey.asc
sudo cp syncthing-pubkey.gpg /etc/apt/trusted.gpg.d/syncthing-pubkey.gpg

gpg --no-default-keyring --keyring ./syncthing-pubkey.gpg --import syncthing-pubkey.asc sudo cp syncthing-pubkey.gpg /etc/apt/trusted.gpg.d/syncthing-pubkey.gpg

sudo sh -c 'echo deb http://apt.syncthing.net/ syncthing release > /etc/apt/sources.list.d/syncthing-release.list'

sudo sh -c 'echo deb http://apt.syncthing.net/ syncthing release > /etc/apt/sources.list.d/syncthing-release.list'

[select code]

sudo apt-get update -qq

sudo apt-get update -qq

[select code]

sudo apt-get install syncthing

Add FoxyProxy to Tor Browser in Whonix.

Warning: Installing FoxyProxy worsens the user's browser fingerprint and adversely affects anonymity since it is not a default Tor Browser add-on. The Tor Project's anonymity warning is explicit:

Can I install other Firefox extensions?

Tor Browser is free software, so there is nothing preventing you from modifying it any way you like. However, we do not recommend installing any additional Firefox add-ons with Tor Browser. Add-ons can break your anonymity in a number of ways, including browser fingerprinting and bypassing proxy settings.

When using a browser and FoxyProxy in combination, a user's web fingerprint becomes more unique. The potential fingerprinting harm to user anonymity depends on how many others are running Tor Browser in conjunction with FoxyProxy.

This configuration is so specialized that probably very few are doing it, reducing the user pool to a small subset. Due to the risk, this approach is generally recommended against. If a user decides to proceed anyhow, the tunnel configuration should not be combined with any browser other than Tor Browser (like Firefox or Chrome), due to an even greater browser fingerprinting risk.

This warning equally applies to configurations such as Tor Browser and I2P, or Tor Browser and remote (http(s)/socks4/5) proxies.

To install FoxyProxy, follow these steps in the Whonix-Workstation (Qubes-Whonix: Whonix-Workstation AppVM).

Make the tbb-foxyproxy config file available to Tor Browser.

[select code]

cp /usr/share/usability-misc/tbb-foxyproxy/foxyproxy.xml /home/user/.tb/tor-browser/Browser/TorBrowser/Data/Browser/profile.default/

cp /usr/share/usability-misc/tbb-foxyproxy/foxyproxy.xml /home/user/.tb/tor-browser/Browser/TorBrowser/Data/Browser/profile.default/

Navigate to addons.mozilla.org.

Tor Browser Menu -> Tools -> Add-ons

Download and install the FoxyProxy add-on.

Search: "foxyproxy" -> Install: FoxyProxy Standard

Restart Tor Browser.

When prompted, select Restart now.

After restart, the FoxyProxy icon should appear in the Tor Browser toolbar and be enabled. Check you can interact with it and change proxy settings as required.

After FoxyProxy is installed, you may see an app-armory warning you about the denied creation of dconf/user. The current Debian profile for Firefox does not yet include the modern temporary file location /run/user. However, this can be safely ignored since FoxyProxy never needs access to this dconf/user. However, if you'd like give the Tor Browser permission to use tempory file directory /run/user/ and not receive the warning, edit the file

[select code]

kdesudo kwrite /etc/apparmor.d/home.tor-browser.firefox

kdesudo kwrite /etc/apparmor.d/home.tor-browser.firefox

And uncomment line

[select code]

# owner /run/user/[0-9]*/** rwkl,

# owner /run/user/[0-9]*/** rwkl,

by removing the #.

To reverse this procedure and restore the default Tor Browser fingerprint:

• Non-Qubes-Whonix: It is best to use a VM snapshot taken before installing the add-on.
• Qubes-Whonix: FoxyProxy should be installed to a specific Whonix-Workstation AppVM set up for proxy purposes. The AppVM can be discarded at leisure.

If Non-Qubes-Whonix users did not take a snapshot prior to these changes, Tor Browser can be downloaded again. Alternatively, FoxyProxy can be removed via the about:addons -> Extensions menu.

For further technical discussion of FoxyProxy, see the Whonix forum.

To open the WebGUI, open Tor Browser and paste:

[select code]

http://127.0.0.1:8384/

http://127.0.0.1:8384/

4. At this point Syncthing back-end should have generated your unique Device ID. Go to:

Actions > Show ID

Share the Device ID along with your OnionCat address. As long as one side shares this information the other can add and find them.

5. Once ID information is exchanged, go to

Add Device

and paste the other endpoint's Device ID. Then under Addresses change dynamic to

[OnionCat-address]:22000

Note that you MUST write the OnionCat IPv6 address within brackets for it to work.

Select the default directory under Share Folders With Device.

6. Syncing more than two endpoints can quickly become tedious so select at least one node to be an Introducer by selecting the option. The Introducer node will inform the new device about all nodes attached to it.

7. Finally drag and drop any files you want to sync to the 'Sync' folder under your Home directory.

Done.

Note: No one can connect to your swarm without you adding them but you may still want to make your virtual network more private. This is done using HiddenServiceAuthorizeClient - a Tor feature.

Torrenting over OnionCat

This section will cover torrenting with anonymous peers inside the Tor network. This is a trackerless setup.

Seeding

1. Set up OnionCat on Whonix Gateway. All parties involved will need to configure a Hidden Service with OnionCat because torrenting is bidirectional.

2. Next install qBittorrent:

[select code]

sudo apt-get install qbittorrent

sudo apt-get install qbittorrent

3. Create your torrent:

Tools > Torrent creator

Add the file/folder you want to share. Leave the Tracker information boxes empty. Insert your OnionCat IPv6 IP into the Comment section.

Check Start seeding after creation then create and save the torrent file.

4. Share the torrent file on your personal Onion Site blog or some other channel as you normally would.

Downloading

1. Add the torrent file in qBittorrent

2. Select the the torrent from the list and go to the General tab. Copy the OnionCat IPv6 address from the Comment section.

3. Click the Peers tab and right-click into the empty tab. Click Add a new peer... and paste the IPv6 address. Note that the default listening port for incoming connections is set to 6881 and nothing needs to be done.

Done.

For a private sharing environment you will need to configure Tor to use the HiddenServiceAuthorizeClient option. More on that here.

Tunnel Freenet over OnionCat

Some Freenet users have successfully experimented with connecting over OnionCat. Note that all communicating parties need to set this up for this to work. Follow this guide to connect to other Darknet peers. No connections to the public datastore possible with this method.

Whonix specific caveats to the above instructions.

Adjust OnionCat to connect to the Gateway with socat.

TO-DO: Create and add socat template to all relevant onion service guides

Pond

Removed because upstream dead.

Pond is a forward secure, asynchronous messaging system that uses Tor to conceal metadata. Pond messages not a record; they expire automatically a week after they are received.

Add Debian Experimental to repos sources lists.

[select code]

sudo su -c "echo -e 'deb http://httpredir.debian.org/debian experimental main' > /etc/apt/sources.list.d/debian-experimental.list"

sudo su -c "echo -e 'deb http://httpredir.debian.org/debian experimental main' > /etc/apt/sources.list.d/debian-experimental.list"

Install Pond and its dependencies.

[select code]

sudo apt-get update
sudo apt-get install golang libgtk-3-dev libgtkspell3-3-dev libtspi-dev
sudo apt-get -t experimental install pond

sudo apt-get update sudo apt-get install golang libgtk-3-dev libgtkspell3-3-dev libtspi-dev sudo apt-get -t experimental install pond

Run Pond.

[select code]

cd
mkdir gopkg
export GOPATH=$HOME/gopkg
$GOPATH/usr/bin/pond-client

cd mkdir gopkg export GOPATH=$HOME/gopkg $GOPATH/usr/bin/pond-client

Optionally set a passphrase and keep the default server selected.

For usage instructions read help --all to understand the options.

HugePages

Huge memory pages improve performance for some virtualized workloads such as running databases. They are not enabled by default in Linux because the amount of memory to be allocated this way depends on the different needs from one user/admin to another.

On the host you need to activate the nr_hugepages setting in the proc filesystem:

echo 1054 > /proc/sys/vm/nr_hugepages

NOTE: To make the above value persistent, you'd need to set:

echo "vm.nr_hugepages=1054" > /etc/sysctl.d/50_hugepages

Then, `grep` for the HugePages_Total:

grep -i HugePages_Total /proc/meminfo 

Should show.

HugePages_Total:    1054

The total system RAM allocated as hugepages can be calculated as:

2Mb * 1054 = 2108 ≈ 2GiB

Then, boot a libvirt virtual machine with 2 GB memory with appropriate XML setting as noted in the example below:

  <memory unit='KiB'>2000896</memory>
  <currentMemory unit='KiB'>2000000</currentMemory>
  <memoryBacking>
    <hugepages>
      <page size='2048' unit='KiB' nodeset='0'/>
    </hugepages>
  </memoryBacking>
  <vcpu placement='static'>8</vcpu>

Clipboard Sharing

SPICE allows accelerated graphics and clipboard sharing. The clipboard is disabled by default for security reasons but could be enabled.

When editing using xml, search for.

<clipboard copypaste='no'/>

And change to.

<clipboard copypaste='yes'/>

KSM

The security assumptions about virtual environments is that each vm is a completely isolated instance that knows nothing about what's happening outside it. It posses a privacy problem for an isolated multi-workstation setup.

In a single workstation-to-gateway scenario, KSM is not problematic because technically, nothing going on, on the gateway, even if known would endanger privacy. However should someone run multiple workstation vms, each with the intent that they are all separated - each with its own internal network for isolation for example, then with KSM all similar activities or processes running in the other vms, would register to an attacker who has compromised one of them. For example, information that the same website has been visited in another vm too. This would allow cross-vm activity correlation.

Its not really a weakness unique to KSM, but a common problem shared by using the equivalent feature on other hypervisors too (Xen's TPS - Transparent Page Sharing).

Quote Memory Deduplication as a Threat to the Guest OS:

4.3 Detection of Downloaded Files

The memory disclosure attack can also be applied to find an opened file on a victim’s VM. We have tried to detect a logo file when Firefox shows a home page.

We confirmed that the Google logo file was detected if page caching is enabled on Firefox. When the page cache was set to 0, detection failed. If an attacker leads a victim to a malicious home page which includes an identifiable logo file, the attacker can detect the page view from the victim’s VM.

This disclosure attack is dangerous because it detects a page view even if the network is encrypted by TLS/SSL. Especially in a multi-tenant data center, this attack is serious, because it does not violate any SLA statements on cloud computing.

Wiping the storage used by a guest domain

A volume used by a domain can contain confidential data, hence it is necessary to wipe it before removal. Libvirt offers a helping hand for such cases:

virsh vol-wipe <volume>

which truncates and extends the volume to its original size. This in fact fills the file with zeroes. This ensures that data previously stored on volume is not accessible to reads anymore. After this, you can remove volume :

virsh vol-delete <volume>

SELinux

SELinux is more robust than Apparmor because its label based vs file-path based. But his comes at the expense of being difficult to write policies. The good news is if you are a KVM user and want to harden your GNU/Linux host, its as simple as enabling SELinux and libvirt will automatically take advantage of it without any further effort needed on your part.

These instructions apply to Whonix and could be easily replicated for your Debian host. First disable Apparmor if you are using it. Both MAC systems cannot be run simultaneously run. This is not supported by LSM and may also be a source of conflicts.

AppArmor is disabled, and the kernel module unloaded by entering the following:

sudo /etc/init.d/apparmor stop
sudo update-rc.d -f apparmor remove

To enable SELinux follow these steps. The cited guide also includes steps for writing custom policy for hardening.

    # aptitude install selinux-basics selinux-policy-default
    # selinux-activate
    # reboot

    # sudo nano /etc/default/grub

    Replace all mention of apparmor in settings for GRUB_CMDLINE_LINUX with selinux=1 and the enforcing=1 parameter to the Linux kernel. The audit=1 parameter enables SELinux logging which records all the denied operations.

    Remove the line under it that starts with: GRUB_CMDLINE_LINUX_DEFAULT

    # update-grub

Updating Tor

Tor was installed on Whonix according to official instructions for Ubuntu. You can update Tor (and the rest of the system) using apt-get update and apt-get dist-upgrade.

If you run in the following error message when running apt-get update on the Gateway...

W: GPG error: http://deb.torproject.org precise Inrelease: The following signature were invalid: Keyexpired 1346668560

...or into the following error message on the Gateway when running apt-get dist-upgrade:

Warning: The following packages cannot be authenticated!
deb.torproject.org-keyring tor
Install these packages without varification?

...please use the workaround below. Please do not install without verification for your own safety!

Temporary fix. Run these two commands. (Check if they are still current and genuine in official instructions for Ubuntu.)

gpg --keyserver keys.gnupg.net --recv 886DDD89

gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | sudo apt-key add -

(If they fail for the first time, perhaps because you are on a slow network or slow Tor circuit, run them a few times until the succeed.)

,, Technical problem: The latest Whonix release is a few days ago and in meanwhile there is a new deb.torproject.org-keyring got renewed while the old torproject deb keys expired. Fixing the problem requires a new Whonix release. It will be fixed in 0.3.0.

## Run Wine to create its directories. Cancel Wine Mono Installer.
wine run

## Create folder for QS components and transfer them.
mkdir /home/user/.wine/drive_c/QS/
unzip QSLite*.zip -d /home/user/.wine/drive_c/QS/
unzip QSAam*.zip -d /home/user/.wine/drive_c/QS/

## Select 'Replace All' when prompted for duplicate files.
A

## Open Terminal and create links to allow QSL and QSA to use Debian gpg:
mkdir .wine/drive_c/QS/gpg-links
link '/home/user/.gnupg/pubring.gpg' '/home/user/.wine/drive_c/QS/gpg-links/pubring.gpg'
link '/home/user/.gnupg/secring.gpg' '/home/user/.wine/drive_c/QS/gpg-links/secring.gpg'

## Run QSL. This way is needed only for the initial run it applies to QSA too. Access QSL from the desktop shortcut afterwards.
cd /home/user/.wine/drive_c/QS
wine qsl.exe

## Setup QSL.
Setup -> Draw randomly in window until "OK" appears ... click "OK" -> Check: Create desktop shortcut | Email Address: yournym@nymphet.paranoici.org -> SMTP Server: gbhpq7eihle4btsn.onion -> Leave SMTP Proxy setings unchanged -> Leave HTTP Proxy setings unchanged -> Finish

(Note: Mixnym's SMTP Onion Service used. Tor Transport used - stream isolation unnecessary)


## Configure QSL.
Open Tools | Options.
...In General tab:
......Under "User Mode", check "Expert".
......Under "On Start-up", check "Open Template Dialog".
...In PGP tab:
......Check "PGP Public Key Encryption".
......For "Private Keyring", use "C:\QS\gpg-links\secring.gpg".
......For "Public Keyring", use "C:\QS\gpg-links\pubring.gpg".
......Click "Default key" and select it (will be just your new one).
......If desired, choose to cache private-key passphrases for five minutes or so.
...In Mix tab:
......Select "once a day" for "Update remailer stats".
...Click "Ok" to finish.
Open Tools | Stats manager.
...Click "Update".
...When you see "done!" click "Ok".
...If it stalls, there's something wrong with your Tor setup.
......Check with Firefox, and also check Tor config in Tools | Proxies.
Open Tools | Allpingers manager.
...Click "Update".
...When you see "done!" click "Ok".


Now you'll configure the message that QSL uses to create a Mixnym nym.
In the main compose pane, customize the message to look like the following:

Code:

Fcc: nyms
Host: gbhpq7eihle4btsn.onion
From: nobody@nowhere.net
Chain: *,*,*; copies=2;
To: send@nymphet.paranoici.org
Subject:

hsub: New Mail For Jude!

-----BEGIN PGP PUBLIC KEY BLOCK-----

mQINBFFP2l4BEACXJDUM6SxyjUk8K+MJ4fRJ5VMaE6hSsAD6n8eO04l9HMzSx26X
<snip>
wnOpR4sYYD9MFLura6+YiHWtT8ih
=ndP9
-----END PGP PUBLIC KEY BLOCK-----

~~

In the above:
...Replace "Jude" in "hsub: New Mail For Jude!" with your fake first name.
...Replace the public key block with your public key that you exported above. Get it by exporting it from KGpg then copy-paste the contents.
...Be very careful near line ends ... Unix vs DOS newline can be buggy here.
...The "~~" at the bottom, preceeded by two blank lines, is crucial!
Save as "nym create template".
...You can reuse it with edits for creating other nyms.
Click the PGP lock and signing icons.
......The mixnym server will only accept signed configuration requests.
Now click "Send" 
"PGP Enrypt to Recipients..." prompt will appear. 
...Choose the Nymserver key from the top pane then click "OK"
Enter your key passphrase when prompted to sign message.
After it finishes, you should see:

Code:

0 in message queue
0 in problem queue
2 sent

All mail sent!

If it worked, the next step is configuring QSA.
If it hangs, cancel out and go back through everything looking for errors.
Close QSL when you're done (and ignore the crash error that you may see).

You can't get a reply from the Nymserver until you configure QSA.


## Run QSA.
cd /home/user/.wine/drive_c/QS
wine qsa.exe

## Setup QSA.
Check: Create desktop shortcut... click "OK" 

If your Nymserver name and type is not listed you must add it first before you can add AAM subject lines encrypted to you.

Open Tools | Nymservers.
...New:
......Nymserver Domain: nymphet.paranoici.org.
......Type: Zax
...Click "OK" then "Done"
Open Tools | AAM Subject Lines.
...New:
...In AAM Subject Line Tab:
......Nym, select your nym's private-key".
......Subject (HSUB), use the one you set or "New Mail For Jude!" if you are following the example above.
...Click "OK" then "Done".
Only one AAM Subject Line can be configured to find your hsub. Be sure to enter it exactly as you did before or else QSA won't find it.
Click "Get Mail" from the main interface. Replies take a while.

KVM GUI Instructions

No longer applies as we are now using vm xml templates for a standard configuration. The rest of the instructions for shared folders and spice have been moved into a readme file distributed with the images.

sudo apt-get update
sudo apt-get install virt-manager

Make sure folder /var/lib/libvirt/images/ exists.

sudo mkdir -p /var/lib/libvirt/images/

Do not use unxz! Extract the images using tar to /var/lib/libvirt/images/.

Before starting the new vm wizard we must create an internal isolated network that connects the workstation with the gateway.

Go to the VMM GUI --> Edit --> Connection Details --> Add button Choose whonix as network name Edit subnet range to 10.0.0.2/24 Uncheck the dhcpv4 option Ignore anything to do with ipv6 Keep the default option of: Isolated Virtual Network selected and click finish.

The next steps may need more work to customize vm devices and clock to safe defaults. Work in this area not final.

Create a Whonix Gateway vm first and choose to edit it before installation. Customize the first NIC that is included to be in default NAT mode. Click to add hardware and chose another NIC. This new NIC must have the newly created isolated virtual network 'whonix' selected as the network device. Finalize and launch. Must enable disk controller as SATA Must select qcow2 as storage format.

Create Whonix Workstation vm and make sure you select the isolated int. network for the only NIC this machine has. Launch. Disk Controller works only with IDE Must select qcow2 as storage format

Don't forget to take snapshot.

Done!

-SPICE is enabled for graphics by default but needs a vdagent to be installed in the guest vms for accelerated 2D in vm to happen. Not included in workstation install by default which impacts performance greatly.

http://www.linux-kvm.org/page/SPICE

It should be safe for use unless you Adrelanos determine otherwise. 2D and 3D in VBox have an insecure architecture and even the manuals admit to this. 2D in VBox is not even available for anything but windows guests which is not recommended and insecure of course. Everything Linux based is designed from the ground up with security considerations in mind.

Clock disabling for vms on host is recommended. Still haven't done it yet, and it seems to need command line.

Enabling SPICE

SPICE allows accelerated graphics and clipboard sharing. Its implications for security are an open question that needs a detailed answer rather than a vague clear cut one.

1. Enable SPICE by selecting it from the VMM GUI. (It is the default option if you decide not select VNC when creating the VM).

Not enabling SPICE from the beginning, will prevent the spice channel device from being added which impacts performance. To fix this add a channel device and select SPICE. This steps is not necessary if you leave the defaults as they are at the beginning.

2. QXL is the GPU model that should be attached.

3. Install vdagent in guest and reboot.

.qcow file size too big?

Short:
It won't really take up 101 GB. Just ~ 2.6 GB. This is an issue with file managers, not Whonix.

Long:

KVM Shared Folders

To move data between the guest and host follow these steps:

1. Set the following settings for shared folders in virt-manager:

The file sharing mode 'mapped' is just an example, using squash or passthrough is possible by selecting them from the drop down menu.

Driver:Default

Mode: Mapped

Source Path: [This is the path of the folder on the Host you are sharing with the Guest]

Target Path: [A custom tag for the shared directory that is used when running the mounting commands within the guest. for example: /tmpshare]

2. Run terminal as root in Guest then use the following command:

mount -t 9p -o trans=virtio [mount tag] [mount point] -oversion=9p2000.L

Mount tag is: /tmpshare

Mount point is the path of the directory that you will share in the Guest with the Host. If it doesn't exist you must create that folder.

Note: you replace the parentheses in the command, they are just a placeholder in this example and should not be typed in.

3. To automatically mount this every time at boot, add the following to your guest's /etc/fstab:

sudo nano /etc/fstab [mount tag] [mount point] 9p trans=virtio,version=9p2000.L,rw 0 0

VirtualBox Guest Additions

Introduction

Written and tested with Whonix 0.2.1 (Ubuntu precise). Many things can go wrong and none or the very least of them will be caused by Whonix. This has only limited support by the Whonix developers, because 1. it is not recommended for security reasons and 2. the guest additions related bugs and instructions are somewhat out of the scope of the Whonix project.

Installation is somewhat difficult and no packages exist. Just search the internet and you'll see, that loads of people having issues installing the VirtualBox guest additions. People having problems for years. VMware is of no alternative, people are also having trouble installing the VMware tools into Linux guests. The issue with the guest additions is ridiculous. For years no solution has been found. With each kernel update, recompilation is required, and quite often, due to some updates, complication becomes difficult or impossible for a long time.

Also see article, [VirtualBox Kernel Driver Is Tainted Crap].

If you are having trouble, than in most cases not because of Whonix. The Whonix setup is a regular Ubuntu Linux and VirtualBox. You can try asking the regular VirtualBox and Ubuntu resources if you have trouble.

TorChat source package

HowTo

EXPERIMENTAL Experimental as in it is difficult to install. Only use it in case you trust TorChat. There shouldn't be any anonymity leaks and it should be as safe as other hidden services in general and in Whonix.

Learn about Hidden Services in Whonix first and learn how to set up the hidden webserver. This will ease following this guide.

On Whonix-Gateway.

Open your /etc/tor/torrc.

sudo nano /etc/tor/torrc

Add.

HiddenServiceDir /var/lib/tor/torchat_service/
HiddenServicePort 11009 10.152.152.11:11009

Save. Reload Tor.

sudo service tor reload

On Whonix-Gateway.

Install dependencies.

sudo apt-get install python python-wxgtk2.8

Get your onion address.

nano /var/lib/tor/torchat_service/hostname

Backup your key, if you want to ever restore it one another machine, a newer Whonix-Workstation or after hdd failure.

/var/lib/tor/torchat_service/private_key

Download the latest Python version of TorChat source code, for example as time of writing torchat-source-0.9.9.553.zip - Python source code (classic standalone 0.9.9 version) from (https://github.com/prof7bit/TorChat/downloads) and store it in /home/user.

Unpack.

unzip torchat-source-0.9.9.553.zip

Get into the torchat source folder. For example.

cd /home/user/torchat-source-0.9.9.553/

Get into the src folder.

cd src

Get into the Tor folder.

cd Tor

Rename tor.sh.

mv tor.sh backup_tor.sh

Go back to the src folder.

cd ..

Create torchat.ini.

nano torchat.ini

Add the following content.

[client]
listen_interface = 10.152.152.11 
listen_port = 11009
own_hostname = <your onion hostname without .onion>

[tor]
tor_server = 10.152.152.10
tor_server_control_port = 9154
tor_server_socks_port = 9154

[tor_portable]
tor_server = 10.152.152.10
tor_server_control_port = 9154
tor_server_socks_port = 9154

Make torchat executable.

chmod +x torchat.py

Run torchat.

./torchat

Alternative

After installing the dependencies we could also force install the torchat deb package.

sudo dpkg -i --force-depends torchat-0.9.9.553.deb

And then configure the files inside /home/user/.torchat. I don't know if that may be the better way.

Mixmaster

MX capable DNS resolver

No longer required.

Mixmaster needs to resolve MX DNS records, while Tor does not support that. We have to install a DNS resolver capable of doing that. It still comes with caveats.

Required knowledge:

• Introduction chapter of Secondary DNS Resolver

The Example with CZ.NIC Labs DNS resolver worked in this case.

Security considerations when replacing the system wide DNS resolver:

• The third party DNS resolver traffic goes through its own circuit, which is good.

• All (custom installed) applications not configured to use a SocksPort (see [Stream Isolation]), would resolve their DNS through the system wide DNS resolver, which would be the third party resolver, giving too much power to it, because it is always the same, only one service provider, not changing like Tor circuits but static. ## Install Postfix ##

  sudo apt-get install postfix ## configure postfix as sattelite system, default settings

Technical background: Mixmaster requires either - a) An (open) smtp server SMTPRELAY in /etc/mixmaster/remailer.conf. Unfortunately, I haven't found any open smtp server (search term: open relay). A mailserver where the user registers first would probably work, but this would defeat the original idea: sending e-mails without depending on registration. Or, - b) a mta (mail transfer agent), which speaks to the remailer directly. TODO: Are there enough Tor exit relays, which allow the SMTP port and does their ISP allow to speak SMTP? If there are too few servers, it could be bad for anonymity.

Open /etc/postfix/main.cf.

kdesudo kwrite /etc/postfix/main.cf

Replace the content with the following.

# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = host.localdomain
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = host, host.localdomain, localhost.localdomain, localhost
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = 
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = loopback-only
inet_protocols = all

relayhost = 1.1.1.1
#relayhost = 2.2.2.2

Debugging Postfix

Looking into the mail log.

tail -f /var/log/mail.info

Should contain something like this.

<date> <time> debian postfix/pickup[id]: id2: uid=1000 from=<user>
<date> <time> debian postfix/cleanup[id]: id2: message-id=<id3.id4@host.localdomain>
<date> <time> debian postfix/qmgr[id]: id2: from=<user@host.localdomain>, size=30000, nrcpt=1 (queue active)
<date> <time> debian postfix/smtp[300]: id2: to=<remailer@breaka.net>, relay=mail.breaka.net[202.75.54.8]:25, delay=30, delays=0.30/0.01/30/3.0, dsn=2.0.0, status=sent (250 OK id=id5-id6-id7)
<date> <time> debian postfix/qmgr[id]: id2: removed

Reading local mail.

## Either with cli tool mail.
mail

## Or using gui tool Icedove (Debian version of Mozilla Thunderbird)
## using movemail.

If all went well, there will be no local mail. Only error messages result in local mails.

Bugs

• In Whonix 0.4.5, due to a Tor Browser upstream bug (they forgot to update the changelog) and because the keyserver is/was down, the torbrowser and whonixcheck script in Whonix can no longer find out which Tor Browser version is locally installed. (Whonix Bug Report) The Update Tor Browser chapter contains a workaround and a fix is available for testers.

E-Mail Notification

Users, who have an (anonymous) sourceforge.net account, could go to the Whonix sf.net Project Page, scroll down to Update Notifications and hit the Subscribe to Updates button. They would receive notifications about new releases sent to their (anonymous) [E-Mail] address.

There is currently no way for users to subscribe to sf.net blogs or wiki, but such a feature has been requested.

Sourceforge.net E-Mail Notification

Didn't work reliable.

E-mail notification: For users having an account on sf.net, there is on sf.net git is an E-Mail subscribe button: M.

This is an example how such a mail could look like:

Restrict Flash Settings

You can skip this chapter. It is no longer of use, because if you use BetterPrivacy as recommended above, you won't need this.

Flash applications can set cookies, so-called Local Shared Objects (LSO), independently of the browser's settings. These cookies are able to save data up to 100 Kb. Usually, they save settings but they may be used to track surfers as well.

In order to manage the settings of your Adobe Flash Player, Macromedia offers a Flash application on its website. There you may e.g. configure the rules concerning the data storage and the rights for using camera and microphone. The settings are spread over several flash applications. Deactivate all functions that allow sharing and saving of data. The storage of LSOs may be deactivated on the Global Storage Settings panel.

Hint: Only in case you previously deactivated JavaScript: You must have Javascript enabled for adobe.com and macromedia.com temporary to run the Flash application.

Furthermore, the cookies already saved have to be deleted. This functionality may be found on the Website Storage Settings panel.

Personal side note: you see how ridiculous that plugin is, if the usage of the Flash settings manager depends on their website being reachable.

Build Documentation dpkg-source commit

To dpkg commit changes, run the debian upstream tarball creation script.

./help-steps/make-debian-package-upstream-tarball

Then run.

dpkg-source --commit

When it asks "Enter the desired patch name:" just enter anything you wish, for example "buildconfig". In the following window, you don't have to fill out anything. Just save and close the editor. You only have to do this once and won't be asked again to do this, unless you add another change which needs to be dpkg-source committed.

If you want to undo the dpkg-source committed change, check the contents of the .pc and the debian/patches folder and delete it.

Build Documentation - Override Whonix Version

Since the Whonix debian package version number is auto derived from git describe and used for Whonix News download, it is recommended to override it. You could add a file to buildconfig.d, for example buildconfig.d/50_version and add for example.

temp="$WHONIX_BUILD_CLOSEST_GIT_TAG"

## Using `export`, so whonix_shared/usr/share/whonix/chroot-scripts-post.d/70_log_build_version can read it.
export WHONIX_BUILD_WHONIX_VERSION_NEW="$(echo "$temp" | sed 's/-/./g')"

echo "WHONIX_BUILD_WHONIX_VERSION_NEW: $WHONIX_BUILD_WHONIX_VERSION_NEW"

WHONIX_BUILD_NEW_CHANGELOG_VERSION=""$WHONIX_BUILD_WHONIX_VERSION_NEW""-debpackage""$WHONIX_BUILD_NEW_DEB_REVISION_VERSION""

echo "WHONIX_BUILD_NEW_CHANGELOG_VERSION: $WHONIX_BUILD_NEW_CHANGELOG_VERSION"

While building, check if WHONIX_BUILD_NEW_CHANGELOG_VERSION looks sane.

If you added a new file to buildconfig.d, for example buildconfig.d/50_target_arch, those have to be dpkg-source committed before building Whonix. Otherwise you'll get an error message. (Which looks like this:).

(1) Go to https://www.torproject.org/ and/or http://idnxcnkne4qt76tg.onion/ and download the Tor Browser Bundle for Linux 32 bit. Store it in /home/user/.

(2) Read https://www.torproject.org/docs/verifying-signatures.html.en and/or http://idnxcnkne4qt76tg.onion/docs/verifying-signatures.html.en and learn about gpg verification.

(3) Go to https://www.torproject.org/docs/signing-keys.html.en and/or http://idnxcnkne4qt76tg.onion/docs/signing-keys.html.en to get the gpg keys.

(4) Verify the Tor Browser Bundle download.

(5) Go into /home/user/ with the file manger. (Dolphin)

(6) Extract the Tor Browser Bundle. Right click on the downloaded archive -> extract -> extract archive here.

(7) In case you downloaded another version than en-US, rename the tor-browser_lang folder to tor-browser_en-US. This is important, because the paths in the following script are hardcoded.

(8) Go into the /home/user/tor-browser_en-US folder.

(9) Delete start-tor-browser or move it to the /home/user/tor-browser_en-US/Docs folder.

(10) Create a new file within the /home/user/tor-browser_en-US/ folder called start-tor-browser with the following content.

#!/bin/bash
## Whonix Tor Browser start script

export TOR_SKIP_LAUNCH=1
    
cd ~
~/tor-browser_en-US/App/Firefox/firefox --profile ~/tor-browser_en-US/Data/profile
    
## End of Whonix Tor Browser start script

(11) Make the start-tor-browser script executable. Right click on start-tor-browser -> Properties -> Permissions -> enable the Is executable box -> ok.

(12) Go to /home/user/tor-browser_en-US/Data/profile/ and create a file user.js with the following content.

## Begin of patched user.js.

## If you edit this file while Firefox is running, your changes will be
## overwritten, when you close Firefox.

## How to create the user.js network settings:
## 1. Make a backup of prefs.js.
## 1. Start Tor Browser with the patched start script.
## 2. Apply proxy settings using the Tor Button settings dialog..
## 3. Make a diff from the old and the new pref.js.
## 4. Copy the relevant changes to user.js.

## network settings
## (Are now set in /etc/environment - or not...)
## (See /etc/environment.)
user_pref("extensions.torbutton.use_privoxy", false);
user_pref("extensions.torbutton.settings_method", "custom");
user_pref("extensions.torbutton.socks_host", "10.152.152.10");
user_pref("extensions.torbutton.socks_port", 9100);
user_pref("network.proxy.socks", "10.152.152.10");
user_pref("network.proxy.socks_port", 9100);
user_pref("extensions.torbutton.custom.socks_host", "10.152.152.10");
user_pref("extensions.torbutton.custom.socks_port", 9100);

## End of Whonix user.js.

(13) If you want to make 100% sure you never have Tor over Tor, you must shut down Whonix-Gateway while doing the following.

(14) Delete /home/user/my_tor-browser_en-US/App/tor.

(15) If there is no green Vidalia icon in the task bar, everything is fine.

(16) Start Tor Browser and run

ps aux | grep tor

If you see something like.

109 /usr/sbin/tor

Or.

/home/user/my_tor-browser_en-US/App/tor

Something went wrong and you're running Tor over Tor, which is recommended against.

(17) If the tests results are as expected, everything went fine.

(18) Don't forget to restart Whonix-Gateway, if you shut it down in step (13).

(19) Done.

DummyTor

Introduction

Whonix-Workstation has an empty Tor package installed by default, called Dummy Tor package. It contains no files, besides some default files, which are required to create a dummy package. Debian packages are standard Unix ar archives, auditors can unpack and check them.

The reason for installing the Dummy Tor package inside Whonix-Workstation is to prevent installing the Tor package from the upstream (Debian or The Tor Project) repository, to prevent running Tor over Tor. This allows installation of packages, which depend on Tor, such as TorChat and parcimonie on Whonix-Workstation.

To prevent the package from upgrading

echo "tor hold" | sudo dpkg --set-selections

has been run while building Whonix from source code.

To check the status an auditor could run.

dpkg --get-selections | grep tor

To undo holding the packing a user could run.

echo "tor install" | sudo dpkg --set-selections

Implementation

• Everything is inside the whonix_workstation/usr/local/share/whonix/dummytor/ folder in Whonix source code
• and subsequently in /usr/local/share/whonix/dummytor/ in Whoix-Workstation.
• .deb package format
• /usr/local/share/whonix/dummytor/tor is the control file
• /usr/local/share/whonix/dummytor/tor_1.0_all.deb is the package which was installed using dpkg by whonix_workstation/usr/local/share/whonix_internal_install_script.
• whonix_workstation/usr/local/share/whonix/dummytor/dummytor is the "build script" for the package, which is actually only a single "equivs-build ./tor" command.

FoxyProxy Sandboxing Warning

Tor Browser will soon ship with sandboxing on an opt-in basis. Unfortunately, the initial sandbox versions are incompatible with this configuration and it must not be enabled. Users with AppArmor enabled may see Tor Browser profile warning messages. These messages can be safely ignored, since they do not prevent FoxyProxy functioning at this time.

Remove Proxy Settings - Whonix 0.5.6

It is best to get a fresh copy of Tor Browser, which has never been started before.

Whonix modifies user.js as documented in the Tor Browser chapter.

Open /home/user/tor-browser_en-US_my/Data/profile/user.js.

kwrite /home/user/tor-browser_en-US_my/Data/profile/user.js

Comment out all network settings.

## network settings
#user_pref("extensions.torbutton.use_privoxy", false);
#user_pref("extensions.torbutton.settings_method", "custom");
#user_pref("extensions.torbutton.socks_host", "10.152.152.10");
#user_pref("extensions.torbutton.socks_port", 9100);
#user_pref("network.proxy.socks", "10.152.152.10");
#user_pref("network.proxy.socks_port", 9100);
#user_pref("extensions.torbutton.custom.socks_host", "10.152.152.10");
#user_pref("extensions.torbutton.custom.socks_port", 9100);

You could use Tor Button's settings dialog to set it to any other proxy or transparent torification. The latter means "no proxy", which will result in Tor Browser using whatever the operating system provides and if you don't have a VPN installed inside Whonix-Workstation, it will go through Tor's TransPort.

If you are using the transparent torification option in Tor Button, you could point a socksifier to start-tor-browser and it should work as usual.

If you are having problems, it is most likely a problem with Tor Browser / Tor Button's proxy settings. In Tor Browser open the pseudo url "about:config" and search for "network.proxy" and check if these settings are sane.

Warning

There are various update mechanisms. Not all are equally secure. Whonix recommends against using Tor Browser's internal updater for security reasons. Using Tor Browser Updater (Whonix) is recommended. To enable you to distinguish them, here are some screenshots of the various updaters.

Whonix 0.5.6 Disable Auto Login

OPTIONAL. Only in case you want to do that.

If you aren't using Physical Isolation, i.e. if you use the Default-Download-Version (Virtual Machines), it is probably better to use the desktop locking mechanism of your host operating system.

These features are inherited from Debian and its packages.

Tor Browser in Whonix 0.5.6

Introduction

The regular Tor Browser Bundle and Tor Browser in Whonix slightly differ. Tor Browser has been slightly modified by Whonix to work behind the Whonix-Gateway. The network and browser fingerprint however, is the same.

Tor Browser's internal update check mechanism is untouched and works fine. Default homepage is untouched and still https://check.torproject.org.

New Identity Button

Note that, if you are using the Tor Browser, which comes with Whonix, that the New Identity button of Tor Button is defunct (greyed out). This is because Tor Button can not access Tor's control port. Due to Whonix Technical Design, Tor Browser and Tor are isolated from each other, which means there is no way to fix this without loosing the added security by Whonix.

When using the regular Tor Browser Bundle (not Whonix!), the New Identity button unlinks your old identity, changes your circuit (exit relay IP) and creates a fresh identity.

As a workaround close Tor Browser, change your circuit with Arm and start Tor Browser again.

This is not a big issue, since the New Identity button is not perfect yet anyway, there are open bugs.

(New Identity Button will be fixed in Whonix 6 and above.)

Whonix Proxy Settings / user.js

When running torbrowser -update, the update script creates a user.js file, for example ~/tor-browser_en-US/Data/profile/user.js. User.js is used to override some Tor Button defaults, namely the SocksProxy settings and other minor misc settings. See also the Tor Browser sub chapter on the Stream Isolation page.

More than one Tor Browser in Whonix

For better isolation of different identities. For advanced users. Moved to the Advanced Security Guide.

Manually updating Tor Browser

(1) Go to https://www.torproject.org/ and/or http://idnxcnkne4qt76tg.onion/ and download the Tor Browser Bundle for Linux 32 bit. Store it in /home/user/.

(2) Read https://www.torproject.org/docs/verifying-signatures.html.en and/or http://idnxcnkne4qt76tg.onion/docs/verifying-signatures.html.en and learn about gpg verification.

(3) Go to https://www.torproject.org/docs/signing-keys.html.en and/or http://idnxcnkne4qt76tg.onion/docs/signing-keys.html.en to get the gpg keys.

(4) Verify the Tor Browser Bundle download.

(5) Go into /home/user/ with the file manger. (Dolphin)

(6) If you still have the old version of TBB opened (because you are probably reading this from the old TBB), close it. (copy the next steps to Kwrite if necessary)

(7) Rename your old TBB /home/user/tor-browser_en-US to something else.

(8) Extract the Tor Browser Bundle. Right click on the downloaded archive -> extract -> extract archive here.

(9) In case you downloaded another version than en-US, rename the tor-browser_lang folder to tor-browser_en-US. This is important, because the paths in the following script are hardcoded.

(10) Go into the /home/user/tor-browser_en-US folder.

(11) Delete start-tor-browser or move it to the /home/user/tor-browser_en-US/Docs folder.

(12) Create a new file within the /home/user/tor-browser_en-US/ folder called start-tor-browser with the following content.

#!/bin/bash
## Whonix Tor Browser start script

export TOR_SKIP_LAUNCH=1
    
cd ~
~/tor-browser_en-US/App/Firefox/firefox --profile ~/tor-browser_en-US/Data/profile
    
## End of Whonix Tor Browser start script

(13) Make the start-tor-browser script executable. Right click on start-tor-browser -> Properties -> Permissions -> enable the Is executable box -> ok.

(14) If you want to make 100% sure you never have Tor over Tor, you must shut down Whonix-Gateway while doing the following.

(15) Delete /home/user/my_tor-browser_en-US/App/tor.

(16) If there is no green Vidalia icon in the task bar, everything is fine.

(17) Start Tor Browser and run

ps aux | grep tor

If you see something like.

109 /usr/sbin/tor

Or.

/home/user/my_tor-browser_en-US/App/tor

Something went wrong and you're running Tor over Tor, which is recommended against.

(18) If the tests results are as expected, everything went fine.

(19) Don't forget to restart Whonix-Gateway, if you shut it down in step (13).

(20) Done.

More than one Tor Browser in Whonix

WARNING: "More than one Tor Browser in Whonix" instructions have not been updated for TBB 3.x yet!

As the Warning page stated, Whonix doesn't magically separate your different contextual identities and since Tor Browser and Tor Button do not yet solve this, for further separation of identities you could use Multiple Whonix-Workstations, which would be more secure.

Alternatively, less secure than Multiple Whonix-Workstations, you could start multiple instances of Tor Browser and run them through different SocksPorts. The instructions in the Manually Downloading Tor Browser article need minimal changes.

Instead of

#!/bin/bash
## Whonix Tor Browser start script

~/tor-browser_en-US/App/Firefox/firefox --profile ~/tor-browser_en-US/Data/profile

## End of Whonix Tor Browser start script

Use

#!/bin/bash
## Whonix Tor Browser start script

## Adjust the path!
~/tor-browser_2/App/Firefox/firefox --profile ~/tor-browser_2/Data/profile -no-remote

## End of Whonix Tor Browser start script

Only -no-remote was added to the start script. Otherwise Tor Browser would connect to the already running Tor Browser and this is not what you want. And don't forget to adjust the path to the other Tor Browser.

You also have to use a different SocksPort, see Change/Remove Proxy Settings. (See Stream Isolation page for explanation why you should use different SocksPorts.)

Trusting the key

Download the key from multiple sources

A simple technique to increase the trust you can put in the Whonix signing key would be to download it several times, from several locations, several computers, possibly several countries, etc.

You could also use this technique to compare keys downloaded by your friends or other people you trust.

Downloading the key from the same server only lowers the possibility of a man-in-the-middle attack for a part of the route. The following figure illustrates that best:

user <-> user ISP <-> internet <-> sourceforge.net ISP <-> sourceforge.net server
MITM less likely for this route |  no help for this route

For this reasons adrelanos' homepage, which describes and contains adrelanos' OpenPGP key is mirrored at six different places. Download adrelanos' key from all those places and store it as adrelanos1.asc, adrelanos2.asc, adrelanos3.asc, etc.

1. adrelanos' homepage on github; (key download)

Github.com is accessible over SSL.

2. adrelanos' key page on sourceforge; (key download)

SSL available for users logged into sourceforge.net.

3. adrelanos' homepage on gitorious; (key download)

Gitorious.org is accessible over SSL.

4. adrelanos' homepage on torproject.org wiki

SSL available. Anyone can edit the torproject.org wiki and exchange content with malicious one. Therefore check the history feature. Obviously, I do trust Tor and torproject.org. My wiki account "proper" should be genuine, therefore changes by "proper" should be legit.

5. adrelanos OpenPGP key mirror on savannah.gnu.org profile page

SSL available. The following command is recommended to enforce downloading the key over SSL:

[select code]

## Not forced through Tor, unless you are using Whonix, torsocks or similar.
curl --tlsv1.3 --proto =https --output adrelanos.asc.4 https://savannah.gnu.org/people/viewgpg.php?user_id=89289

## Not forced through Tor, unless you are using Whonix, torsocks or similar. curl --tlsv1.3 --proto =https --output adrelanos.asc.4 https://savannah.gnu.org/people/viewgpg.php?user_id=89289

6. adrelanos' OpenPGP key mirror on OpenPGP keyserver

No SSL. Should really be only used as a mirror.

## Not forced through Tor, unless you are using Whonix, torsocks or similar.
gpg --keyserver x-hkp://pool.sks-keyservers.net --recv-key 916B8D99C38EAF5E8ADC7A2A8D66066A2EEACCDA

7. adrelanos' OpenPGP key in Whonix 6 and above

gpg --import /usr/share/whonix/keys/whonix-keys.d/adrelanos.asc

Verify:

gpg --recv-key 916B8D99C38EAF5E8ADC7A2A8D66066A2EEACCDA

Should show.

pub   4096R/2EEACCDA 2014-01-16 [expires: 2015-01-16]
      Key fingerprint = 916B 8D99 C38E AF5E 8ADC  7A2A 8D66 066A 2EEA CCDA
uid                 [ unknown] Patrick Schleizer <adrelanos@riseup.net>

sub   4096R/0xCB8D50BB77BB3C48 2014-01-16 [expires: 2015-01-16]

Each time you re-import the key from a different source:

gpg --import adrelanos.asc 
gpg --import adrelanos1.asc 
gpg --import adrelanos2.asc 
...

It should always show:

gpg: key 2EEACCDA: "Patrick Schleizer <adrelanos@riseup.net>" not changed
gpg: Total number processed: 1
gpg:              unchanged: 1

And:

gpg --fingerprint

Should always show the same fingerprint and only contain: (Besides keys you imported knowingly earlier, perhaps your friends keys.)

pub   4096R/0x8D66066A2EEACCDA 2014-01-16 [expires: 2015-01-16]
      Key fingerprint = 916B 8D99 C38E AF5E 8ADC  7A2A 8D66 066A 2EEA CCDA
uid                 [ unknown] Patrick Schleizer <adrelanos@riseup.net>
sub   4096R/0x3B1E6942CE998547 2014-01-16 [expires: 2015-01-16]
sub   4096R/0x10FDAC53119B3FD6 2014-01-16 [expires: 2015-01-16]
sub   4096R/0xCB8D50BB77BB3C48 2014-01-16 [expires: 2015-01-16]

Unless the new key is signed with the old key, something fishy is going on.

Whonix 7 OLD Known Issues

Connection Issues - Tor stops working after an Upgrade and needs a Workaround

When upgrading to Tor 0.2.4.19-1~d79.jessie+1 (using sudo apt-get dist-upgrade), your Tor connection may go down. There is a temporary workaround.

Open /etc/default/tor.

## If you are using a graphical Whonix-Gateway, use:
kdesudo kate /etc/default/tor

<!--T:76-->
## Or alternatively, if you are using a terminal-only Whonix-Gateway, use:
sudo nano /etc/default/tor

Scroll down, near bottom comment in (by removing the # in front of it).

USE_AA_EXEC="no"

Then try:

sudo service tor restart

You should keep that in mind and undo that change when Whonix or Tor fixes that bug. We'll keep you posted. (See Download#Stay_tuned and Security_Guide#Recommendation_to_install_latest_security_updates_on_all_systems.)

Forum help thread: Special:AWCforum/st/id287/new_tor_and_debian_updates_today....html

Virtual Box Shared Folder Issues

Shared Folders aren’t working with the latest Linux kernel. (This is a Debian/Virtual Box issue, not caused by Whonix. Has already been reported to upstream by a Debian user.)

Possible workarounds, more information, etc. can be found in the Whonix User Help Forum discussion thread: Special:AWCforum/st/id261/VirtualBox_shared_directories_on....html

Tor Browser Starter (Whonix)

After manually upgrading Tor Browser (see above)... To start Tor Browser, got to your /home/user/tor-browser_en-US folder and double click start-tor-browser. Or type in terminal (Konsole).

/home/user/tor-browser_en-US/start-tor-browser

Tor Browser Updater (Whonix)

Currently broken due to changes by torproject.org. You have to manually update Tor Browser in meanwhile.

Forum help thread: Special:AWCforum/st/id262/updating_TOR_browser_error...html

Enigmail Encryption

When using OpenPGP encryption in Icedove / Enigmail you might get "encryption command failed".

Icedove has been updated in Debian Testing in meanwhile. Upgrade it.

sudo apt-get update
sudo apt-get dist-upgrade

You should then install enigmail as usual:

sudo apt-get install enigmail

Defunct Desktop Shortcuts

The desktop shortcuts Tor Browser, Contribute, Forum, Documentation, Donate won't work until there is an upgrade of Whonix. Please manually visit these pages. How to start Tor Browser has already been explained above.

Whonix-Gateway: Err: http://deb.torproject.org tor-0.2.4.x-jessie/main i386 Packages 404 Not Found

Short answer:
Update and upgrade your underlying Debian system (Whonix is a derivative of Debian).

sudo apt-get update
sudo apt-get dist-upgrade

See also Security_Guide#Recommendation_to_install_latest_security_updates_on_all_systems. This bug will be fixed with next Whonix upgrade (will take some time). No other action strictly required for now.

Long answer:
This is because torproject deprecated that repository. That was to be expected. The repository we're using now is already preconfigured (in /etc/apt/sources.list.d/torproject.list).

Taking action is not important at this stage. You can comment it out (by putting a # in front of it) in /etc/apt/sources.list.d/torproject.list if you want. (kdesudo kate /etc/apt/sources.list.d/torproject.list for graphical Whonix-Gateway or sudo nano /etc/apt/sources.list.d/torproject.list for terminal-only Whonix-Gateway) If you don't do it, it will be auto fixed with next upgrade of Whonix.

apt-get Hash Sum mismatch

If you get a hash sum mismatch when updating through sudo apt-get update then deleting the package lists should solve it. A hash sum mismatch can look like:

W: Failed to fetch http://ftp.us.debian.org/debian/dists/testing/contrib/i18n/Translation-enIndex  Hash Sum mismatch

To delete the package lists, run:

sudo rm -fR /var/lib/apt/lists/*

To make sure everything works like it should, update your package lists and upgrade your distro. Chances are that your previous update/upgrade attempts have failed due to the mismatch.

sudo apt-get update && apt-get dist-upgrade

(Source )

There is no public key available for the following key IDs

The message "There is no public key available for the following key IDs" is not necessarily an error. It might be just a warning/information.

sudo apt-get update
...
Reading package lists... Done
...
W: There is no public key available for the following key IDs:
9C131AD3713AAEEF

Check the exit code of apt-get.

echo $?
0

When it is 0, there is no problem. This is due to key transition, because Whonix's repository is currently signed with the old and the new signing key.

Reasons for Staying Anonymous Developer

Security and trust shouldn't depend on showing a face:

• Tails (w)

KVM

Convert

Converting is only required if you want to use the stable version of Whonix. No longer required for testers-only versions, see:
https://www.whonix.org/blog/category/testers-wanted/

1. Extract the downloaded Whonix ova images to obtain the VMDK virtual storage files.

tar -xvf ~/Whonix.ova

As of now, VMDK files cannot be directly used by KVM or converted to a file type supported by KVM.

VBoxManage clonehd --format VDI vmdk_file vdi_file

(You need to adjust the names vmdk_file and vdi_file.)

2. Use qemu-img to convert the vdi to qcow2. Why qcow2? Because it supports snapshotting, which is very useful for reverting Whonix-Workstation to a known clean state. You must not revert gateway snapshots of the gateway vm as that will change your guard nodes which is not good for anonymity. This would increase your chances of having a rogue guard node and exit.

qemu-img convert -p -O qcow2 ~/whonix.vdi ~/whonix.qcow2

System Requirements

• • • Lucid has been reported, not to work. Since it is only supported until 2013-04 it won't be fixed.

I2P

Clock Skew Issues

Whonix 9:
Should have no issues.

In Whonix 8:
I2P-0.9.11 this doesn't work - I2P complains about clock skews even after disabling both sdwdate and bootclockrandomization.

sudo service sdwdate stop
sudo chmod -x /etc/init.d/sdwdate

It is still possible to fix the clock manually. For example, if I2P reports a clock skew of 60 seconds at startup, use this command to change system time:

sudo date -s now-60sec

then restart I2P.

However, time sync management in Whonix is a complex issue, so before changing the default way of time management in Whonix, make sure to read Dev/TimeSync and understand the implications.

old known issues

gpg keyserver unreachable

Open gpg.conf.

kwrite ~/.gnupg/gpg.conf

Search for all instances of "keyserver". And comment them out, i.e.

Upgrade from Testers repository

Whonix's testers-only repository contains a fix. If you like to volunteer as a tester, see Whonix-APT-Repository on how to enable it, so this change can move soon into Whonix's stable repository. After enabling it, upgrade.

Physical Isolation

Install Basic Packages

This step is only required up to and including Whonix 8. Versions higher than Whonix 8 do not require this manual step anymore.

Make sure you have all packages installed which are listed in the file grml_packages. You can do that using the following command.

sudo apt-get install $(grep -vE "^\s*#" grml_packages | tr "\n" " ")

Why was Whonix 7 based on Debian Testing, not Debian Stable?

• Contains python-stem, which is a Tor controller library. It is in use to ask for Tor's bootstrap status. This is required for whonixcheck (diagnosing connection issues) and TimeSync (TimeSync starts as soon as Tor is bootstrapped). See this ticket for more details. The alternative, uploading python-stem to Whonix's APT Repository is not doable given Whonix's contributor size. (It would require keeping up with the original package and updating when they update. And implementing the feature, allowing builders to build Whonix from source code without touching Whonix's APT repository for Trust reasons would also have been more difficult.)
• Being based on stable and incorporating a few packages from testing is difficult, see this ticket for details.
• Contains build dependency config-package-dev with debhelper support. (We could probably build on stable and just get the config-package-dev with debhelper support elsewhere, but it is simpler just to require Debian testing as build operating system.
• Stable (Wheezy) contains only obfs2 (obfsproxy 0.1.4), while Testing (Jessie) contains obfs3 (obfsproxy 0.2.3), and obfsproxy has been recently removed from torproject's apt repository.

Whonix 9 OLD Issues

Connection Issues - Tor stops working after an Upgrade and needs a Workaround

This is fixed in Whonix 9.2 above.

In Whonix 9... When upgrading to Tor 0.2.5.8-rc-1~d70.wheezy+1 (using sudo apt-get dist-upgrade) in Whonix 9, your Tor connection may go down. There is a workaround.

Open /etc/apparmor.d/local/system_tor.

## If you are using a graphical Whonix-Gateway, use:
kdesudo kate /etc/apparmor.d/local/system_tor

## Or alternatively, if you are using a terminal-only Whonix-Gateway, use:
sudo nano /etc/apparmor.d/local/system_tor

Scroll down until you see.

/usr/bin/obfsproxy rix,

Comment out (by adding a # in front of it).

#/usr/bin/obfsproxy rix,

Then reboot.

sudo reboot

You should keep that in mind. When Whonix fixes that bug, you'll get an interactive dpkg conflict resolution dialog. This is explained in Security Guide#Updates. Just choose to install the new /etc/apparmor.d/local/system_tor file then.

AppArmor Warning during Boot

If you wonder during boot about following warning.

Warning /etc/apparmor.d/... network rules not enforced.

This is not a security issue. Whonix installs AppArmor and the apparmor-profiles package by default, but does not enforce AppArmor by default. We are not there yet and Debian also does not enforce AppArmor by default yet either. The apparmor-profiles package gets installed by default for better usability, to make enforcing AppArmor easier. This warning only reflects, that the profile is not enforced by default.

VirtualBox Guest Additions

New Instructions for Debian Wheezy

Installation from Debian apt repository

Inside your VirtualBox virtual machine.

Very simple.

Searching for Debian packages containing VirtualBox was a wise thing. In past it was sometimes a real pain to install the guest additions. The search brought up, that honorable people created a debian package with the tools.

1. Update your operating system.

2. Install. Easy:

sudo apt-get install virtualbox-guest-x11

Advanced security? See footnote or skip:

3. Reboot.

4. NOTE: Sometimes after reboot the Workstation guest fails to pick up a new resolution. Try to change the screen resolution manually a few times, from KDE settings. Once it succeeds to change to fullscreen, the change will stay persistent across reboots.

Installing using VirtualBox Instructions

Alternatively, above #Installation from Debian apt repository fails, which should not, you could also refer to the upstream documentation, VirtualBox: Chapter 4. Guest Additions.

Instructions for Debian Jessie

Whonix 10 is based on Debian Wheezy. So unless you are using a Whonix-Custom-Workstation based on Debian Jessie, you most likely want to use above instructions. Otherwise press expand on the right side.

Not sure if the jessie instructions are still up to date. Maybe the ones for wheezy also work for jessie just fine.

Inside your VirtualBox virtual machine.

This version is difficult to get working with guest additions and vbox shares. Debian Jessie has the issue that Whonix installs with Kernel 3.10 and the distro is at 3.12, and the 3.10 headers are not available. Therefore, it is dangerous (and unsafe) to get the Kernel headers on a different repository. Additionally, there are reports that updating the kernel can cause issues (and is also unsafe).

Noteː It has been reported that reverting Virtualbox 2 versions back with 3.10 can also solve issues. Update this wiki with your results.

Build Warnings

• Short: Don't install apt-listchanges as custom package during VM image builds or don't have it installed during --target root builds.

Long: Because likely might change the build process from a non-interactive one to an interactive one. You're better off purging apt-listchanges.

sudo apt-get purge apt-listchanges

Alternatively, you could use a non-interactive frontend for apt-listchanges such as text. To do so, you would have to edit /etc/apt/listchanges.conf.

sudo nano /etc/apt/listchanges.conf

[apt]
frontend=text

After Whonix has been build, you're free to reinstall apt-listchanges.

Tor Browser

Change/Remove Proxy Settings

This is an advanced topic. You most likely only need it for advanced tunneling scenarios.

You could either:

• Use Tor Button's -> Preferences to set it to any other proxy or no proxy. Transparent Torification means, "no proxy" or in other words it means "use whatever the system provides".

1) Click on Tor Button.
2) Click on Preferences.

3) Choose Transparent Torification.

4) Click OK.

• For an alternative method, setting Transparent Torification which does not involve Tor Button's graphical user interface, see footnote .
• Forget about Tor Button's -> Open Network Settings. See footnote, if you want to know why.

Grub Fix

Introduction

The following instructions differ for 686-pae and 486 kernel users.

Are you are 686-pae kernel kernel or 486 kernel user?

• If you previously did not choose any options right after starting Whonix in the grub boot menu, if you don't know what this is about, then you're very likely a 686-pae Kernel User.
• If you are used to picking the 486 kernel as per page Starting Whonix, chapter Boot Options, then you already know, that you're a 486 Kernel User.

686-pae Kernel Users

Remove the 486 and 586 kernel meta packages.

sudo apt-get remove linux-image-*-486 linux-image-*-586

Remove the 486 and 586 kernel packages.

sudo apt-get remove linux-image-3.*-486 linux-image-3.*-586

Make sure a kernel is installed.

sudo apt-get install linux-image-686-pae

Proceed with #Install Grub chapter!

486 Kernel Users

Remove the 686-pae kernel meta packages.

sudo apt-get remove linux-image-686-pae

Remove the 686-pae kernel packages.

sudo apt-get remove linux-image-3.*-686-pae

Make sure a kernel is installed.

sudo apt-get install linux-image-486

Proceed with #Install Grub chapter!

Stream Isolation

Limited workarounds for Tor Browser

Possible

1. Weakest: On Tor Browser, click on the Torbutton and then click on "New Identity". However your current browser session will be lost.

2. Better: Install a second browser and configure it to use its own SocksPort, see More than one Tor Browser in Whonix.

3. Even better: Use multiple Whonix-Workstations.

IsolateDestAddr and IsolateDestPort for Tor Browser (Recommended against!)

Qubes

Torified dom0 Updates

Now in Qubes wiki.

Go to Qubes VM Manager -> System -> Global Settings. See the UpdateVM setting. Choose your desired Whonix-Gateway ProxyVM from the list. For example: sys-whonix.

Qubes VM Manager -> System -> Global Settings -> UpdateVM -> sys-whonix

Qubes-Whonix Gnome Workstation

OR, to install Workstation with complete Gnome applications that are installed in Qubes Fedora templates:
For Gnome, read security notes on Other Desktop Environments.

• Input command:
  sudo qubes-dom0-update --enablerepo=qubes-templates-community qubes-template-whonix-ws-gnome

2. Increase Update Size

The Gnome version of the Whonix-Workstation TemplateVM may be too large and will you need to increase the allowed update size to accommodate installing it.

In Dom0 -> Terminal:

• Input command:
  export UPDATES_MAX_BYTES=$[ 4 * 1024 ** 3 ]

AppArmor

At the moment, if you want to use this, you must apply these settings to the TemplateVMs as well as the TemplateBasedVMs. Once Qubes Q3 gets released, TemplateBasedVMs will inherit the kernelopts setting of their TemplateVM.

Edit Firewall Rules

2. Edit Whonix-Workstation Firewall Rules

In Dom0 » Qubes VM Manager:

• Select Whonix-Workstation AppVM:
  • Edit VM firewall rules:
    • Select: Deny network access except...
    • Disable: Allow ICMP traffic
    • Disable: Allow DNS queries
    • Disable: Allow connections to Updates Proxy
    • Press: OK

Misc

This guide will create a new instance of a Whonix-Gateway ProxyVM, which routes all internet traffic through Tor, that you can then connect your Whonix-Workstation AppVMs to.

You can repeat this guide multiple times and create as many Whonix-Gateway ProxyVM instances as you need, for greater Tor isolation. Note that using multiple Whonix-Gateway ProxyVMs simultaneously will reveal a pattern of connecting to multiple sets of Tor guard nodes, which may or may not be a unique usage indicator.

This guide will create a new instance of a Whonix-Workstation AppVM, which serves as an AnonVM application environment, that you connect to Tor through a Whonix-Gateway ProxyVM of yours.

You can repeat this guide multiple times and create as many Whonix-Workstation AppVM instances as you need, for greater Tor and data isolation. You can connect multiple Whonix-Workstation AppVMs to the same or different instances of Whonix-Gateway ProxyVMs.

If connecting this AppVM to the internet, you will need an existing Whonix-Gateway ProxyVM instance to connect to. You may need to create a Whonix-Gateway ProxyVM before proceeding.

If you wish to keep your version of Whonix up-to-date you should also enable the Whonix Repository. You should apply this process to all of your Whonix TemplateVMs. In otherwords, make sure you follow these directions for both your Whonix-Gateway (commonly called whonix-gw) and Whonix-Workstation (commonly called whonix-ws).

When running the Whonix, Whonixcheck will automatically tell you if Debian package updates are available (Debian is the version of Linux that Whonix is built upon).

3. Enable Whonix repository

When first running a Whonix TemplateVM, a window called "Whonix Setup Wizard" should automatically pop up.

In Whonix Setup Wizard:

* Select "Yes. Automatically install updates from the Whonix team"
* Click <Next>
* Choose which Whonix Repository (recommended: Whonix Stable Repository)
* Click <Next> 
* Click <Finish>

To Manually Restart Whonix Repository Tool

You may also manually start the Whonix Repository Tool to change your settings in the future by doing the following from your respective Whonix TemplateVMs (i.e. Whonix-Worstation, Whonix-Gateway, etc.)

In a terminal:

sudo whonix_repository

Or by running:

Start Menu -> Applications -> System -> Whonix Repository.

You may need to first create a Whonix-Gateway ProxyVM to use, if one does not exist yet.

Note: If you are installing Whonix on top of Qubes OS, you do not need to worry about disabling ICMP timestamps at this stage. You will do that after you install the Whonix-Gateway and Whonix-Workstation TemplateVMs when you create your Whonix VMs (done through the Qubes VM Manger). For more information on this, refer to the links provided under the Next Steps section (point's a and b) in the Install Guide for installing Whonix onto Qubes.

Whonix 10 TemplateVM Update

With the advent of Whonix 11, the update guide for Whonix 10 is now deprecated If you are still using Whonix 10, you are advised to install Whonix 11 If you are still interested in updating Whonix 10, click on Expand on the right.

This guide explains how to update your Whonix TemplateVMs using the update repositories.

You should regularly apply this update process to all of your Whonix-Gateway and Whonix-Workstation TemplateVMs.

1. Attach Whonix TemplateVM to a Whonix-Gateway ProxyVM (commonly called sys-whonix)

You may need to first create a Whonix-Gateway ProxyVM to use, if one does not exist yet.

In Dom0 » Qubes VM Manager:

• Select Whonix TemplateVM » VM Settings » Basic tab » NetVM:
  • Choose an existing Whonix-Gateway ProxyVM from the NetVM list for downloading updates.

2. Start Whonix TemplateVM

In Dom0 » Qubes VM Manager:

• Select Whonix TemplateVM:
  • Start selected VM

3. Launch TemplateVM Terminal

In Dom0 » Application Launcher Menu:

• For your Whonix TemplateVM's launcher menu, click on the "Terminal" app to launch it.

4. Enable Whonix Repository

Qubes and Debian updates install by default. If you would also like to install Whonix updates this way, then ensure you have the Whonix repository enabled -- (or disabled if you prefer). This setting will remain in your TemplateVM for later. On first run of template you will be presented with the Whonix repository options, but you may change them at any time.

In Whonix TemplateVM » Terminal:

• Input command: sudo whonix-setup-wizard repository
  • Choose: Yes. Automatically install updates from the Whonix team.
  • Press: OK
  • Choose: Whonix Stable Repository (unless you are a tester or developer and understand what you are doing).
  • Press: OK

5. Check and Install Updates

In Whonix TemplateVM » Terminal:

• Input command: sudo apt-get update && sudo apt-get dist-upgrade -y

• OR, You can right click the Whonix templateVM in Qubes Manager and select Update

6. Clear Terminal History

In Whonix TemplateVM » Terminal:

• Input command: history -cw

7. Shutdown Whonix TemplateVM

In Dom0 » Qubes VM Manager:

• Select Whonix TemplateVM:
  • Shutdown selected VM

8. Restart/Update Whonix VMs

If new updates were available and installed, you will need to either simply restart your running Whonix-Gateway ProxyVMs and running Whonix-Workstation AppVMs for them to be updated -- or alternatively apply this same update process again to your running VMs if not wanting to restart them right away.

Before installing

First you need to have the Qubes OS installed on your system. A helpful Installation Guide for Qubes OS 3.0 is found here

However, before installing Qubes OS on your system, after you have downloaded the Qubes ISO, make sure that you follow the Qubes OS security advice for verifying the signatures of the Qubes ISO found here

After you have Qubes OS up and running on your system, before you install Whonix you must next

Read and apply the Pre-Installation Security Advice.

Enigmail / gpg / keyserver

Since enigmail just calls gpg. And since everything is torified in Whonix anyway, and since gpg is stream isolated (by uwt wrapper) anyhow, there is no need for this setting in Whonix.

Infrastructure

File Hosting

Files are still hosted on sourceforge.net.

Negative:

• No direct download links (hotlinking).
• No SSL.
• Advertisements.

Positive:

• Unlimited quota and traffic. (Although we should remove old releases from time to time.)

Bug / Feature Request Tracker

Now hosted on github: https://github.com/Whonix/Whonix/issues

A bit suboptimal, since people have to create a second account just for github and it probably won't scale well enough in long term. Positive points are, that it works for many big projects such as Bitcoin and attracts a lot pull requests (for them). So let's see how that works.

Old Criteria and Plan for Web Hosting

Requirements for Good Hosting

Requirements

• Some webspace and sufficient traffic.
• Needs a wiki, a forum, a blog, a mailing list.
• We can either use free project hosting or own hosting.
• Tor friendly.
• No tracking scripts. (Google analytics etc.)
• Permit to sign up and to use the page exclusively over Tor.
• A wiki on that site (media wiki). (And spoilers.) (And flagged revisions.)
• A free SSL certificate.
• All parts off the website reachable over SSL without any warnings.
  • sourceforge.net does not offer that (SSL warnings).
  • startssl.com offers free SSL certificates. You simply have to prove, that you have control over the domain - but that's not possible with subdomains.
• Hosting and domain.
  • Censor resistant in sense of "Whonix will not get deleted."
  • Free - if that is possible. No one is willing to pay and in the beginning there are no donations.
• We allow guest/anonymous postings (bug report, feedback, etc.) and moderate it very non-restrictive. (Allow any critique. Only delete off topic talk such as warez.)
  • It is still desired to have the less critical parts of the wiki open for guest edits.
  • Where no random trolls/crackers can modify anything important.
  • A wiki where guest edits are allowed only works when having a feature for Flagged revisions Sighted versions, where admins review changes and manually make the edited version the default visible page for everyone. To my knowledge, only mediawiki has such a feature.

Reviewed Hosting Services

sourceforge.net

In past, all components of Whonix were hosted on sourceforge.net. Whonix still uses sourceforge.net as primary bulk file download service. Unfortunately, sourceforge does not provide direct download links (hotlinking).

The internal wiki, forum and the mailing list and download mirrors provided by sf.net provide unlimited traffic, which is very good.

The forum provided by sourceforge.net was not very well suited for Whonix. Most users are expected to post to the forums over Tor. sourceforge.net doesn't handle changing IP's very well. Registered users often had to post twice until their message got stored. And if they haven't stored their draft beforehand it was lost, which was really annoying. Positive points were, that the forum was viewable over SSL, but only for registered users. Let's say user's managed to successfully post a message, then it was still confusing because the message had to be manually moderated due to automatic spam scripts targeting Whonix forum. Sourceforges wiki was unfortunately not viewable over SSL, which was very bad.

sf.net generally provides two different categories of hosting. Allura with "some" SSL, i.e. the wiki, forum, mailing list, download mirrors on the other hand project web.

Project web (no SSL) has somewhat low limited traffic, but according to their support will be manually increased.

One of the major issues with sf.net is, that is does not support SSL everywhere. In past, the Contribute page contained a Vote chapter and one of the votes users are encouraged to, was Idea #721: Allow SSL for SourceForge pages whenever possible. Unfortunately, very few users voted.

A very strong point for sf.net is, that big files (virtual machine images) and unlimited traffic are allowed. Another strong one of course is, that sf.net allows Whonix to be hosted on sf.net.

Sourceforge.net blocks users from "Cuba, Iran, North Korea, Sudan, Syria".

Other severe usability bugs:

• Improve Support for Tor Browser; option to disable IP check
• Prevent drafts from getting lost
• Long content pages broken

Google Code

• Google Code blocks users from "Cuba, Iran, North Korea, Sudan, Syria".
• No file downloads.

wikimedia / wikpedia

Last time we checked wikipedia (wikimedia) derivatives and wikia weren't Tor friendly.

savannah

• https://savannah.nongnu.org (with SSL) looked promising and they are expected to be gone soon or to do any other stupid stuff (banning countries etc.).
• They offer homepages, for example http://www.nongnu.org/qwe/ but seems like there are no subdomains (qwe.nongnu.org) with SSL (for nongnu.org). That's the minimum requirement.
• Support direct download links (hotlinking).
• Can't provide file hosting for Whonix, because it would cause too much traffic.

github

• Already using github as main git repository.
• github.com offers sub domains, but they are not reachable over SSL.
• github triggers a scary, error message. After either many pages trigger that error so it doesn't matter any more or until this message gets fixed in Tor Browser, we shouldn't use the github as issue tracker or website to avoid FUD. When that got somehow a non-problem, we could think about using github as issue tracker.
• How autocreate table of contents using markdown on github? But...
• Github also supports mediawiki syntax.
  • Seems it automatically creates a table of contents, good!
  • Bug: Mediawiki Pictures now shown in Github Wiki, unless this bug gets fixed, we could think about using the github source code hosting as website, see example.
  • We haven't found out yet how to use \[\[include ref=WikiHeader\]\] for github mediawiki pages. It is an important feature for Whonix pages.
  • Looks like mediawiki support is just a gimmick. More advanced formatting like font size, syntax highlighting and so on doesn't work.
• No file hosting service.

gitorious

• Nice as a git mirror. In use as a git mirror.
• SSL for the whole page including the wiki.
• The wiki supports less features, no html (not that important) and no tables. The side bar takes too much space and leaves too less page for the wiki. The wiki is more suited for smaller documentation but not as a whole website replacement like Whonix needs.
• No file hosting service.

self hosted hidden service

• Adrelanos is not willing to do it.

free onion hosting service

• We could host a website on third party (free) hidden service webspace service.
• Risky, because those services can go away any time without notice. - Looks like a valid risk, two just went down.
• Can they handle the load when we release a new version? Not talking about bandwidth. Just about page views.
• Clearnet users could only access them through onion.to and tor2web.
  • onion.to has a scary landing page.
  • tor2web does not yet appear in search engines

mirror.fsf.org

• http://mirror.fsf.org/
• Providing direct download links (hotlinking).
• Probably it will not be possible. They have a quite firm policy (Guidelines for Free System Distributions) and if Debian didn't manage to fulfill it, surely Whonix can't either.
• In theory, an option could be to base Whonix on a distribution which is on their list already, but that might not be doable for technical reasons. (Questions open up, such as: Are they in sync with Debian unstable? Are they in sync with Debian testing? How long does it take until they deploy updates from security.debian.org? How up to date are their packages? How are they different from Debian?)
• Whonix contacted FSF to be their list. Thes declined, because Whonix is not standalone. (Does not fulfill point "Complete Distros", since physical isolation users have to install Debian first.)

seul.org

• Sent registration request for seul.org. They don't accept new registrations, but Roger Dingledine (surprise, surprise) said in private mail, he's seeding Tails already and would volunteer to seed Whonix, if there was an announcement mailing list or if we mailed him new releases. Doing this.

Conclusion

In summary there where no open source hosting sites, which offer SSL everywhere and unlimited download of big files. An open source hosting facility providing free webspace and SSL everywhere would be much desirable, but doesn't exist.

Hosting Services to be reviewed

General Questions

• Download traffic?
• Quota?
• Direct download links (hotlinking) possible?
• Optional: SSL downloads?

Mirror Providers

There are a few lists

• http://sourceforge.net/apps/trac/sourceforge/wiki/Mirrors#MirrorProviders
• http://mirror.slitaz.org/mirrors
• http://www.freebsd.org/doc/handbook/mirrors-rsync.html
• http://www.debian.org/distrib/archive

of mirror providers. We could contact them and ask if there were willing to provide direct download links (hotlinking) (+SSL) for Whonix.

When they are able to sponsor sourceforge, in comparison, sponsoring Whonix would be only peanuts to them. The question is, if they provide service for individual requests.

codeplex

• Seem to offer direct download links. Just stored some random download links to see how long the direct link is valid.
• https://kinectmultipoint.codeplex.com/downloads/get/692328
• http://download-codeplex.sec.s-msft.com/Download/Release?ProjectName=kinectmultipoint&DownloadId=692328&FileTime=130174287196930000&Build=20602

bitbucket

• Seem to offer direct download links. Just stored some random download links to see how long the direct link is valid.
• https://bitbucket.org/pypy/pypy/downloads
• http://cdn.bitbucket.org/pypy/pypy/downloads/pypy-2.1-beta1-arm-armhf-raspbian.tar.bz2

autistici

https://vpn.autistici.org could be asked, if they were willing to act as webseed.

alioth

http://alioth.debian.org could be asked, if they accepted Whonix as a new project, related enough to Debian, then they might be used as webseed.

Asked

• http://linux.psu.ru/ linux at psu.ru
  • November 2013: wants to test Whonix for a few months and then decide

• November 2013: mirror.aarnet.edu.au
  • asked where their sourceforge folder is
  • and if they tell us: asked if we may use them as master mirror for other mirrors

• November 2013: mirrorservice.org
  • asked if we are allowed to directly download from them
  • asked if we may use them as master mirror for other mirrors

Answer:

We have no problem with you direct linking to us or you suggesting other
sites using us to mirror from (we offer rsync too).

But bear in mind that the data in that mirror is controlled by
SourceForge. They don't ship all files to all mirrors - each mirror
specifies how much data it can take, and they put stuff on up to that
limit based on popularity (presumably). Their delivery mechanism knows
which files are on which mirrors, so end users don't get pointed at a
mirror that doesn't contain the file they're after.

So it is possible that we may not have a complete copy of all your files,
and it may change in the future without any intervention from us.

If you're happy with that situation then go ahead and link to us.

Answer to follow up email:

We don't have any upload facilities I'm afraid. We only offer downloads.

One solution is to run a private rsync server yourselves that only
certain mirrors can access. It doesn't have to be that quick.

You may find other mirrors do offer an upload facility though.

• November 2013: switch.ch
  • asked for an upload account
  • asked for master rsync capabilities

Answer:

Dear Sir 

Thank you for your e-mail of 25th November 2013 regarding Whonix. 

Sorry, we are not interested in your offer.

Whonix APT Repository URI Sourceforge

To use the sourceforge location uri rather than mirror.whonix.de uri, use the following command line switch. Example.

[select code]

sudo whonix_repository --baseuri http://sourceforge.net/projects/whonixdevelopermetafiles/files/internal/ --repository testers --enable

sudo whonix_repository --baseuri http://sourceforge.net/projects/whonixdevelopermetafiles/files/internal/ --repository testers --enable

XChat

All HexChat plugins have been deactivated (hardening) and deactivated using dpkg-divert. To re-enable them, use one of the following commands depending on which plugin you need.

Open a terminal.

If you are using Qubes-Whonix, complete the following steps.

Qubes App Launcher (blue/grey "Q") -> Whonix-Workstation AppVM (commonly named anon-whonix) -> Konsole

If you are using a graphical Whonix-Workstation, complete the following steps.

Start Menu -> Applications -> System -> Konsole

[select code]

sudo dpkg-divert --rename --remove /usr/lib/xchat/plugins/python.so

sudo dpkg-divert --rename --remove /usr/lib/xchat/plugins/python.so

[select code]

sudo dpkg-divert --rename --remove /usr/lib/xchat/plugins/tcl.so

sudo dpkg-divert --rename --remove /usr/lib/xchat/plugins/tcl.so

[select code]

sudo dpkg-divert --rename --remove /usr/lib/xchat/plugins/perl.so

sudo dpkg-divert --rename --remove /usr/lib/xchat/plugins/perl.so

Those commands are reverted when Whonix Debian Packages get updated. TODO: Document how to prevent that.

VPN sysvinit

sysvinit: (Legacy. Prefer the systemd method below.)

Repository Location URI

There are two repository location URI's.

• mirror.whonix.de
  • Default: yes.
  • Download speed: fast.
  • Agility: After uploading new packages, it takes ~1 hour until all mirrors on the mirror.whonix.de mirror system upgraded.
  • Target audience: most users.
• sourceforge
  • Default: no.
  • Download speed: slow.
  • Agility: After uploading new packages, packages are available almost instantly.
  • Target audience: developers, perhaps testers.

To use the whonix.org location uri rather than mirror.whonix.de uri, use the following command line switch. Example.

VPN DNS Configuration

Currently only manual.

Open /etc/resolv.conf in an editor with root rights.

If you are using a graphical Whonix or Qubes-Whonix, run.

[select code]

kdesudo kwrite /etc/resolv.conf

kdesudo kwrite /etc/resolv.conf

If you are using a terminal-only Whonix, run.

[select code]

sudo nano /etc/resolv.conf

sudo nano /etc/resolv.conf

Comment out.

#nameserver 10.152.152.10

Add.

## Riseup.net OpenVPN DNS server
nameserver 172.27.100.1

If you are not using riseup, you need to replace 172.27.100.1 and enter the virtual LAN IP address of your VPN providers DNS server. You might be able to obtain it from your VPN provider. You can also try to infer it after successfully connecting to the VPN from running "sudo route". The first destination default gateway should function as DNS server also.

Save.

If you want to be sure, that /etc/resolv.conf does not get overwritten by other packages. (Such as DHCP or resolvconf.)

sudo chattr +i /etc/resolv.conf

If you ever want to remove it, use -i.

(A more usable way is TODO research, help welcome. As possible starting point, see footnote. )

Firejail

3. Optional - edit janondisttorbrowser.desktop in an editor with root rights.

Open /usr/share/applications/janondisttorbrowser.desktop in an editor with root rights.

If you are using a graphical Whonix or Qubes-Whonix, run.

[select code]

kdesudo kwrite /usr/share/applications/janondisttorbrowser.desktop

kdesudo kwrite /usr/share/applications/janondisttorbrowser.desktop

If you are using a terminal-only Whonix, run.

[select code]

sudo nano /usr/share/applications/janondisttorbrowser.desktop

sudo nano /usr/share/applications/janondisttorbrowser.desktop

4. Optional - prepend the Exec= line with "firejail"

   Exec=firejail torbrowser %u

Save and exit.

Note:

3. Optional - edit firefox-esr.desktop in an editor with root rights:

Open /usr/share/applications/firefox-esr.desktop in an editor with root rights.

If you are using a graphical Whonix or Qubes-Whonix, run.

[select code]

kdesudo kwrite /usr/share/applications/firefox-esr.desktop

kdesudo kwrite /usr/share/applications/firefox-esr.desktop

If you are using a terminal-only Whonix, run.

Preparation

You need newer control port filter / upgrade to Whonix 14 developers-only. You get it by upgrading to Whonix 14 developers-only.

Upgrade both Whonix-Gateway and Whonix-Workstation to Whonix 14 developers-only. For instructions see: Upgrading_Whonix_13_to_Whonix_14

Or use Whonix 13.0.0.1.4 developers-only from https://forums.whonix.org/t/whonix-13-0-0-1-4-developers-only/3486/3 or newer (if existing).

Configure Control Port Filter Proxy

On Whonix-Gateway.

Control Port Filter Proxy needs some adjustments.

[select code]

sudo cp /usr/share/tor-controlport-filter-merger/examples/40_onionshare.yml /etc/tor-controlport-filter-merger.d/

sudo cp /usr/share/tor-controlport-filter-merger/examples/40_onionshare.yml /etc/tor-controlport-filter-merger.d/

Restart Control Port Filter Proxy.

[select code]

sudo service tor-controlport-filter restart

sudo service tor-controlport-filter restart

Configure Whonix-Workstation Firewall

Inside Whonix-Workstation.

Modify Whonix-Workstation User Firewall Settings

Note: If no changes have yet been made to Whonix Firewall Settings, then the Whonix User Firewall Settings File /etc/whonix_firewall.d/50_user.conf appears empty (because it does not exist). This is expected.

If using Qubes-Whonix, complete these steps.
In Whonix-Workstation AppVM.

Make sure folder /rw/config/whonix_firewall.d exists.

[select code]

sudo mkdir -p /rw/config/whonix_firewall.d

sudo mkdir -p /rw/config/whonix_firewall.d

Open /rw/config/whonix_firewall.d/50_user.conf with root rights.

[select code]

kdesudo kwrite /rw/config/whonix_firewall.d/50_user.conf

kdesudo kwrite /rw/config/whonix_firewall.d/50_user.conf

If using a graphical Whonix-Workstation, complete these steps.

Start Menu -> Applications -> Settings -> User Firewall Settings

If using a terminal-only Whonix-Workstation, complete these steps.

[select code]

sudo nano /etc/whonix_firewall.d/50_user.conf

sudo nano /etc/whonix_firewall.d/50_user.conf

For more help, press on Expand on the right.

Note: The Whonix Global Firewall Settings File /etc/whonix_firewall.d/30_default.conf contains default settings and explanatory comments about their purpose. By default, the file is opened read-only and is not meant to be directly edited. Below, it is recommended to open the file without root rights. The file contains an explanatory comment on how to change firewall settings.

## Please use "/etc/whonix_firewall.d/50_user.conf" for your custom configuration,
## which will override the defaults found here. When Whonix is updated, this
## file may be overwritten.

See also Whonix modular flexible .d style configuration folders.

To view the file, follow these instructions.

If using Qubes-Whonix, complete these steps.

Qubes App Launcher (blue/grey "Q") -> Template: whonix-ws -> Whonix Global Firewall Settings

Timesync

Hardware clock: Set to UTC. OpenSSL (used by Tor) leaks it, but that is of no concern. Tor is running on Linux and Linux is expected to be run in UTC. Therefore there is no point to set it to the local time zone of the user.

• • An adversary could guess if someone is running a hidden service with constant clock adjustments, that it is hosted inside a Whonix-Workstation. It is unknown if the clock adjustments by sdwdate are big enough to enable an adversary to guess that.
    • TODO: Open question... "ntpd adjusts the clock in small steps so that the timescale is effectively continuous and without discontinuities" - is that possible with a sdwdate like approach as well? -> Working on sclockadj.

• • Running sdwdate also every [ 1440 minutes + random(0-1440) ]. Not running this every hour at a random time, because Tor does not like clock jumps. [deprecated because sclockadj] When testing this, there were cases where the clock jumped about 800 seconds, which caused Tor to expire circuits, which caused connection interrupts.
  • TODO: Open question... How often should sdwdate run on Whonix-Gateway? Every hour is a bad idea, as we see above. Not running it again when some people may run Whonix-Gateway for days or weeks is not good either, since the clock can drift. Maybe it should run wait 24 hours and then wait a random amount of minutes within 24 hours? -> Will be solved when sclockadj gets finished.

• • • The entry guard or bridge can see the time through TCP timestamp.
    • Continuous clock jumps could help the entry guard or bridge guessing, that a Whonix-Gateway is connected.
    • TODO: Open question... "ntpd adjusts the clock in small steps so that the timescale is effectively continuous and without discontinuities" - is that possible with a sdwdate like approach as well? -> Will be solved when sclockadj gets finished.

• sdwdate is designed to be as secure as TLS (RFC 2246) but of course the security of TLS is often reduced to whichever CA racket you believe is trustworthy. By default, sdwdate uses curl that by default trusts your local CA root store - so when any of these companies assist in a MITM attack, malicious time information could be feed into your system.
