Redirect ports or unix domain socket files from Whonix-Workstation localhost to Whonix-Gateway.

Introduction[edit]

Port or unix domain socket file redirection could be useful for any future applications that expect Tor or the ControlPort to listen on any specific port or unix domain socket file that is not (yet) added to anon-ws-disable-stacked-tor build-insarchive.org or configarchive.org by default, or for any other port or unix domain socket file redirections from the workstation to the gateway.

Instructions[edit]

To create a port or unix domain socket file, it is required to create and extend config file /etc/anon-ws-disable-stacked-tor.d/50_user.conf. [1]

1. Inside Whonix-Workstation.

2. Platform specific notice.

  • Non-Qubes-Whonix: No special notice.
  • Qubes-Whonix: users should use folder /etc/anon-ws-disable-stacked-tor.d rather than folder /usr/local/etc/anon-ws-disable-stacked-tor.d/ and apply this in whonix-workstation-17 Template. [2]

3. Create folder /usr/local/etc/anon-ws-disable-stacked-tor.d/.

sudo mkdir -p /usr/local/etc/anon-ws-disable-stacked-tor.d

4. Open file /usr/local/etc/anon-ws-disable-stacked-tor.d/50_user.conf in an editor with root rights.

Non-Qubes-Whonix

This box uses sudoedit for better security.

Qubes-Whonix

NOTE: When using Qubes-Whonix, this needs to be done inside the Template.

Others and Alternatives

  • This is just an example. Other tools could achieve the same goal.
  • If this example does not work for you or if you are not using Whonix, please refer to this link.

sudoedit /usr/local/etc/anon-ws-disable-stacked-tor.d/50_user.conf

5. Port redirection or unix domain socket file redirection.

A) Either add a port redirection.

For example to redirect Whonix-Workstation port 9100 to Whonix-Gateway port 9050. Note: adjust the port numbers for your needs.

file_port_tuples+=" port#9100:9050 "

B) Unix domain socket file redirection.

Create a unix domain socket file /var/run/anon-ws-disable-stacked-tor/unix-domain-socket-file.sock and have it forwarded to Whonix-Gateway port 9050.

file_port_tuples+=" /var/run/anon-ws-disable-stacked-tor/unix-domain-socket-file.sock#9050 "

6. Save.

7. Run the systemd-socket-proxyd systemd-unit-files-generator. [3]

sudo /usr/libexec/anon-ws-disable-stacked-tor/systemd-unit-files-generator

8. Done.

The process of creating a redirection is now complete.

Testing[edit]

To test /var/run/anon-ws-disable-stacked-tor/unix-domain-socket-file.sock, you could use:

socat - UNIX-CONNECT:/var/run/anon-ws-disable-stacked-tor/unix-domain-socket-file.sock

Then type:

GET

Then press <enter>.

The expected reply includes Tor is not an HTTP Proxy.

  2. ↑ The missing Qubes-Whonix feature is that /usr/libexec/anon-ws-disable-stacked-tor/systemd-unit-files-generator doesn't run at boot time and that files generated by /usr/libexec/anon-ws-disable-stacked-tor/systemd-unit-files-generator don't persist after reboot of a TemplateBasedVM.
