The SSH tunnel be configured on the host or inside Whonix-Gateway ™.

Install SSH Client[edit]

sudo apt update

sudo apt install ssh

Test Connection[edit]

ssh yourusername@your.ssh.server

  • TODO: Public key authentication steps

apt install lynx

lynx check.torproject.org

exit

Configure Local Server[edit]

ssh -D 1080 your.ssh.server

  • TODO: Run in background on each start up before Tor.

Configure Tor[edit]

Option 1: Use Anon Connection Wizard[edit]

Beginning with Whonix ™ 14, a prefixed proxy can be configured easily using Anon Connection Wizard.

Step 1: Start Anon Connection Wizard[edit]

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

Qubes App Launcher (blue/grey "Q")Whonix-Gateway ™ ProxyVM (commonly named sys-whonix)Anon Connection Wizard

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

Start MenuApplicationsSystemAnon Connection Wizard

If you are using a terminal emulator (such as for example xfce4-terminal) on Whonix-Gateway ™, type.

lxsudo anon-connection-wizard

If you are using a CLI Whonix-Gateway ™, see footnote. [1]

Step 2: Use Proxy Configuration Page[edit]

Select "Use proxy before connecting to the Tor network" on the Proxy Configuration pageChoose the proxy typeFill out other necessary information

Info Tips: 1. Proxy Type

The proxy type is the protocol which is used to communicate with the proxy server. Since there are only three options, they can all be tried until one works.

2. Proxy IP/hostname

It is necessary to know the proxy IP for attempted connections. If the user is trying to connect to a local proxy, then 127.0.0.1 should be specified since it is the localhost.

3. Proxy Port number

It is necessary to know the port number for attempted connections. It should be a positive integer from 1 to 65535. If searching for the listening port number of a well-known censorship circumvention tool, it can be found online.

4. Username and Password If the username and password are unknown, they should be left blank to see if the connection will succeed. In most cases they are not needed.

Option 2: Manually Configure Proxy[edit]

Open file /usr/local/etc/torrc.d/50_user.conf in a text editor of your choice with sudoedit.

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 MenuApplicationsSettings/usr/local/etc/torrc.d/50_user.conf

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

sudoedit /usr/local/etc/torrc.d/50_user.conf

  • If SSH tunnel was setup from Whonix-Gateway ™:

Socks5Proxy 127.0.0.1:1080

  • If SSH tunnel was setup from host operating system, change IP:PORT as needed:

Socks5Proxy IP:PORT

Firewall Configuration[edit]

  • TODO: if running inside Whonix-Gateway ™, new firewall rules are probably required.

Footnotes[edit]

  1. Anon Connection Wizard is a graphical user interface (GUI) application. It does not have command line interface (CLI) support yet. It is therefore unavailable on Whonix-Gateway ™ CLI. Use setup-dist instead; note that functionality is limited and does not support Bridges.
