The SSH tunnel be configured on the host or inside Whonix-Gateway ™.
Install SSH Client[edit]
Install package(s) openssh-client
.
A. Update the package lists and upgrade the system.
sudo apt update && sudo apt full-upgrade
B. Install the openssh-client
package(s).
Using apt
command line parameter --no-install-recommends
is in most cases optional.
sudo apt install --no-install-recommends openssh-client
C. Done.
The procedure of installing package(s) openssh-client
is complete.
Test Connection[edit]

Configure Tor[edit]
Option 1: Use Anon Connection Wizard[edit]
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 Menu
→ Applications
→ System
→ Anon 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 page
→ Choose the proxy type
→ Fill out other necessary information
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 Menu
→ Applications
→ Settings
→ /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]
- ↑
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.
