Yeah, I got it set up through Cockpit actually

Streamlined VM deployment inside a headless server. Been scratching my head for 2 days now on getting a Debian VM to work as advertised. Every step of the way I keep thinking “surely it doesn’t have to be this difficult, right?” And for some reason, a basic netplan edit to make a bridge broke all my NFS binds. Took all day to sort a brand new permissions issue that shouldn’t be possible

Can someone educate me on why the more common ones like Debian and Arch aren’t on this list? Every single day Linux communities force me to look at computer stuff in a different light

Edit: I learned a lot and accidentally incited discourse oops

Ah, I thought operation didn’t matter, my bad

Faraday cage?

it’s full duplex

“The other end”? As in my NAS? Because I can’t check that machine due to lack of SSH

Oh sorry, nothing network related (as far as my novice ass can tell). I’m talking about my Jellyfin containers. Tons of excuses related to things that haven’t changed

“Speed: 1000Mb/s”. I was under the impression that my HDD (Seagate EXOS) would be roughly double that with some to spare.

Sad to report it is not working. Instead I’m getting a different error every time I try to play media

In a response to just_another_person below, it seems to be a Tailscale hangup

Great answer, thank you. To your point, I tried to disable the Tailscale service on my Ubuntu machine and the consequences were bad enough that I’m going to try to avoid Tailscale as much as possible. In disabling it, it also shut down open-ssh, so I had go to the machine with a keyboard and monitor (gross). Re-ran iperf3…while still a bit lower than I’d expect, I don’t think I have any room to complain here all things considered.

“-bash: syntax error near unexpected token `newline’” I’m not familiar with ethtool, but I looked up some commands related to ethtool. Unfortunately, everything I tried give me “bad command line argument(s)”

Of course, cat7a just tested all the cables too

Interesting. I’ve been using Tailscale for years, this is the first I’ve heard of it causing LAN networking problems. I thought the purpose of Tailscale was to establish a low maintenance VPN for people who won’t/can’t set up a reverse proxy, especially for beginners like myself. Later today I’ll try to clear it out and report back

Oh yeah, Tailscale. I’ll run iperf without it to compare, but I’ve never had an issue with my tailnet before

still not great. And I think ‘sudo tailscale up --accept-routes’ broke my shit. Now SSH is failing. I’m calling it a night, I’ll report back tomorrow

Know any Linux magic to try out?

192.168.0.4 and 192.168.0.44 for NAS and server, respectively. Currently just an idle Jellyfin container. I’m not sure what bridge networking is without looking it up, so I’m assuming that’s not happening here

Right, but how to solve it?
