Can't get it to work on latest git (or stable version on arch) from arch to arch. Different errors for Desktop and Laptop
Hello!
I use lan-mouse git on both of my machines (same commit). Using arch with niri as the environment
❯ lan-mouse --version
lan-mouse 0.10.0
tag:latest
commit_hash:89684e14
build_time:2025-02-21 13:07:10 +00:00
build_env:rustc 1.84.1 (e71f9a9a9 2025-01-27),stable-x86_64-unknown-linux-gnu
Now, I used lan-mouse in the past with sway, no problem. It does not work with sway either, currently!
Note that I switched the port, but, well... it doesn't work with the default port either.
From my desktop, when I try to go to my laptop, I get this:
[2025-02-21T13:22:37Z INFO lan_mouse::connect] client 0 connecting ...
[2025-02-21T13:22:37Z INFO lan_mouse::connect] client (0) connecting ... (ips: [192.168.1.161:4243])

While the other way around I get this:
[2025-02-21T13:23:50Z INFO lan_mouse::connect] client 0 connecting ...
[2025-02-21T13:23:50Z INFO lan_mouse::connect] client (0) connecting ... (ips: [192.168.1.217:4243])

What am I doing wrong, what can I do to fix this?
Did you authorize the device you want to use?
Say, you want to control device A using device B, then you have to copy the certificat fingerprint of device B and authorize it on device A using the Authorize button.
It should look something like this on the receiving end:
First off: Thank you very much for taking the time to answer!
So this is mandatory now but wasn't before? In any case, I did, while it was running, then disabled the connection again and reenabled it... to no avail.
I have connections configured though... also it didn't save the fingerprints after a restart, so I'll need to manually put them in the config?
The reason it was not mandatory before is because the traffic was unencrypted.
-
Yes, you currently need to either enter the fingerprint every time or put it in your config file. (see https://github.com/feschber/lan-mouse?tab=readme-ov-file#example-config)
-
You now need to configure the connection on the "controling" device only and authorize these devices on the "controlled" devices.
@feschber thanks a bunch!
It works one way now... I can control the desktop from the laptop, but the other way around it says: "connection timed out"... it's weird.
I copied the config and of course I changed the fingerprint and the name of the controlling device. It's all correct, but no luck in the important direction so far!
Anyway, it's probably a layer 8 problem at this point (pebkac), so feel free to close this!
Are you using niri on both ends? What does the log say?
Yes, on both sides. I need to check the log again... on the desktop it says "connection timed out"
Maybe it's because I have 3 monitors on the desktop... (no weird flex, just a weird guess)
So, finally found time to check again.

Desktop says, when I move the mouse over to where the laptop should be:
