The Steam discussion forum for Rust/Linux was shut down a few days ago, and the list of Linux/Proton servers I was maintaining there disappeared with it, so here is the new thread:

Rust Linux / Proton Enabled Servers

For anyone who hasn't tried it recently, Rust runs flawlessly under Proton these days - in fact it runs better than the native Linux version ever did (before they shut it down)! The only problems are a) you can't view the in-game server list (trying will hang the game) and b) there are only a very limited number of servers you can connect to - they must have EAC disabled.

If you know of any other Linux-enabled Rust servers please let me know on the above thread, or if you're having trouble setting one up I'm happy to help. The software for HOSTING a Rust server natively on Linux is still going strong, no problems there.
