Issues with Discord / Online Games

[Spaghetto392]

Hi,

I recently got in contact with some old friends, and have been talking to them over Discord. We have been playing online games such as "Valheim" and "Deep Rock Galactic," However, every time I join the voice channel on Discord, or try to join a game online, I have to disable Opensnitch.

I thought this was originally an issue with ICMP traffic being blocked by Opensnitch, but now that that issue seems to be fixed, I am not ultimately sure what is happening. Allowing the traffic in Opensnitch doesn't do anything as far as I can tell.

Oddly enough, other software such as Element, and Signal both work fine under Opensnitch, so I'm guessing it's some form of different network traffic being blocked. I've read parts of the documentation I think would be relevant, but I'm still fairly new to networking and firewalls, so it is possible I've missed something very obvious.

Given, I don't believe this is a bug, I've filed this under 'discussions' instead of issues. Any help would be greatly appreciated.

Hi @Spaghetto392 ,

What opensnitch version are you using? 1.6.x? and are you using Discord desktop client or the browser?
Could you enable [x] Debug invalid connections under Preferences -> Nodes, and see if you're prompted to allow "Outgoing connections".

The desktop client opens connections to ports in the 50xxx range for sound, do you see connections logged to that ports range?

Also setting LogLevel to DEBUG would be useful, under Preferences -> Nodes. For example, after changing the log level and before joining the voice channel, emtpy the log (sudo truncate -s0 /var/log/opensnitchd.log) and then join the voice channel. Once you reproduce the problem, copy the log to other directory (/tmp, etc). That should help to locate the problem.

Hi @gustavo-iniguez-goya

Quick question, what is the equivelant in the JSON config for Debug Invalid Connections? I'm using NixOS which requires configuring via configuration.nix, the version is 1.6.2

Opensnitch also currently doesn't seem to be storing a log. I'm looking into that right now.

Thank you.

[Spaghetto392]

Oh, I should also clarify, I'm using web Discord. Checking traffic, no ports other than 53 and 443 are being used.

[Spaghetto392]

I don't know if this is useful on it's own, given I haven't enabled Debug Invalid Connections, but I thought I would provide it anyways. There are some errors popping up about non existent files for some reason.

Hi @gustavo-iniguez-goya

Quick question, what is the equivelant in the JSON config for Debug Invalid Connections? I'm using NixOS which requires configuring via configuration.nix, the version is 1.6.2

"InterceptUnknown": true

For reference, I am using Armcord, which is an Electron wrapper around Discord's web UI. Same results happen on Firefox and Chromium.

ok! by the way, according to the logs, it looks like opensnitch configured monitor method is "proc" (config item: ProcMonitorMethod).
If the config item is set to "ebpf" then the eBPF modules are not loaded, or failed to load.

Review it if it's not intended. When the daemon starts up, it writes the following messages to the log file:

[2024-02-12 13:29:16]  INF  [eBPF] module loaded: /usr/lib/opensnitchd/ebpf/opensnitch.o
[2024-02-12 13:29:16]  INF  [eBPF] module loaded: /usr/lib/opensnitchd/ebpf/opensnitch-procs.o
[2024-02-12 13:29:16]  INF  Process monitor method ebpf
[2024-02-12 13:29:16]  INF  [eBPF] module loaded: /usr/lib/opensnitchd/ebpf/opensnitch-dns.o

[Spaghetto392]

Hi,

Firstly, thank you for your reply. Yes, Opensnitch is currently using "proc" on my device. Due to the kernel I'm using, linux-hardened (I believe it's the same on as Arch) not having eBPF, and the kernel module not working for one reason or another. I eventually intend to fix this but haven't had the time.

So, with InterceptUnkown set to true, after allowing an unknown connection through, I was able to actually join a call in Discord, albeit one with only myself, and it does show it's using a UDP port in the 50000 range.

Here is the relevant part of the log:

Hopefully this helps.

@gustavo-iniguez-goya Just wanted to make sure that you saw the logs. That and I wanted to ask, should this be moved to issues instead of discussions?

Thank you.

[gustavo-iniguez-goya]

Thank you for the logs @Spaghetto392 . Unfortunately using 'proc' may cause these issues. The logs doesn't show attempts to connect to the port > 50000, there should be at least a "new connection ..." log.

Anyway I'll try to reproduce it using proc, to see if is there anything we can do to improve the behaviour.

[Spaghetto392]

Hi @gustavo-iniguez-goya thank you for your reply. So from the looks of it, proc is the issue? Out of curiosity, would audit be a better option for my use case? I still have had little luck with eBPF.

[Spaghetto392]

Hi, @gustavo-iniguez-goya just wanted to ask, has there been any progress on this issue? Looking at other games, this seems to be a fairly common issue for multiplayer. I did a few months ago attempt to reach out to the creator of the NIXOS eBPF kernel module, but had no luck.
