Originally created by @jakob1379 on GitHub (May 5, 2025).

Describe the problem

I have multiple netbird tunnels which works using systemd-resolv, but I can't start netbird UIs for each tunnel

To Reproduce

create two or netbird setups, start netbird-ui for each tunnel:

❯ /nix/store/jcb5a2n10pky18y4fp9r981qls8qx7fq-netbird-0.43.1/bin/netbird-ui  --daemon-addr=unix:///var/run/netbird-homelab/sock
INFO[0000] subscribed to daemon events

# ---------- in other shell ----------

❯ /nix/store/jcb5a2n10pky18y4fp9r981qls8qx7fq-netbird-0.43.1/bin/netbird-ui  --daemon-addr=unix:///var/run/netbird/sock
WARN[0000] another process is running

Expected behavior

Since tunnel work I expect one UI pr tunnel to work as well.

Are you using NetBird Cloud?

Yes

NetBird version

0.43.1

Is any other VPN software installed?

No

The netbird-ui process checks whether there is another process on the system using the same binary and exits if it finds one. You would need to rename the UI binary to make multiple instances work.

I run this setup on nixos using the nix config for Netbird on unstable defining multiple clients, which uses the wrapper library. I thought this actually did this already, but apperently not.

I thought this actually did this already, but apperently not.

This is a relatively new addition (10 months) compared to the NixOS module, which is not officially supported (I wrote it ~3 years ago, started upstreaming ~2 years ago, then barely touched it after that).

For NixOS specifically, it would be great if you could add an intermediate symlink at the wrapper and confirm whether it works.

I've checked the process name gets changed when using symlinks, you'll just need to make sure the basename is different for each instance:

kdn@brys ~/d/g/n/netbird-support (main)> cat -n args.py 
     1  #!/usr/bin/env python
     2  from pprint import pprint
     3  import sys
     4  
     5  pprint(list(enumerate(sys.argv)))
kdn@brys ~/d/g/n/netbird-support (main)> ln -s args.py args-renamed.py
kdn@brys ~/d/g/n/netbird-support (main)> ./args.py
[(0, './args.py')]

sorry about the delay, had a wedding where I had to perform as the groom...

nonetheless intermediate symlinks work, I am not yet that strong in nix, so I dare not suggest an edit as I am not sure the best approach to follow.

With profiles now being a thing this is less of an issue, thought being able to have multiple networks connected would still be nice, besides the security concerns it brings
