For some context, here is my previous guide on fixing snowflake in whonix from earlier today.

https://forum.qubes-os.org/t/qubes-whonix-17-tor-snowflake-proxy-setup-guide-that-works/28844

In my last guide at the top of this post, I showed how to get snowflake proxy working in Qubes-Whonix(sys-whonix), by replacing the default (outdated?)bridges found in the whonix(qubes-whonix) snowflake documentation and bypassing qubes-whonix's Tor Control Panel, on top of configuring DNS settings specific to qubes-whonix. This guide will show you how to get the snowflake proxy in sys-whonix's Tor Control Panel working using the same principal, if you find that to be useful. (It feels nice to click snowflake and it not stop at 10%, and it frees up your Tor User Config.)

If this has been done before, or if this is trivial/pointless then I apologize, but I like when things are made to be easy for people, and if I can help, I will(i hope I'm helping at least). So here we go.

This procedure was first tested in the sys-whonix VM as root, do it in the whonix-gateway-17 template for persistence.

This guide assumes the user has already configured sys-whonix's dns using sudoedit /etc/resolv.conf.whonix and setting the output of qubesdb-read /qubes-netvm-primary-dns as nameserver near the bottom of the file by uncommenting it and changing the ip. It also assumes the user has copied and installed snowflake-client by copying it from the whonix-workstation-17 template to the whonix-gateway-17 template in /usr/bin , and making the file executable.

EDIT: It might be wise to cut network access to sys-whonix while logged in as root

(i'm in the process of testing this in the whonix-gateway-17 template for persistence)

In dom0:(for testing) qvm-run --user root sys-whonix xterm In sys-whonix xterm:(for testing) execute commands below for testing

In whonix-gateway-17 terminal:(Template Install)

cd /usr/share/anon-conection-wizard/

sudo nano bridges_default

Replace the outdated snowflake bridges in the file to these newer ones from the tor project found at this link, I suggest the CDN77 bridges(option 2): https://forum.torproject.org/t/fix-problems-with-snowflake-since-2024-03-01-broker-failure-unexpected-error-no-answer/11755

CTRL+O then CTRL+ENTER (to save file) CTRL+X (to exit file)

Shut down whonix-gateway-17

Start/Restart sys-whonix

Find your Tor Control Panel under Main Qubes Menu > Services > sys-whonix > Tor Control Panel

Click stop Tor

Click Configure

Select snowflake as your bridge type

Start Tor

It should look like this.

Snowflake should connect fine.
