Describe the problem

I tried to enable SSH Access for a few of my peers (Linux & macOS) but it doesn't work

To Reproduce

  1. Enable SSH Access for a peer in dashboard
  2. client.log on the peer shows: WARN client/internal/engine.go:554: running SSH server is not permitted
  3. try to connect connect:
Error: dial tcp 100.102.98.127:44338: i/o timeout
Couldn't connect. Please check the connection status or if the ssh server is enabled on the other peer

Expected behavior

  • Enable SSH access

Hi @florian-obradovic, you need to run this on the client:

netbird down
netbird up --allow-server-ssh

We will update our docs since this information is missing.

allow-server-ssh

Yes its been @sirvar. For docker you need the following environment variable:

NB_ALLOW_SERVER_SSH=true

Thanks for heads up @mlsmaycon

We should add a note to the documentation, that you also need an ACL which allows tcp port 44338 access.

@creeram commented on GitHub (Jan 2, 2025):

@lixmal security feature? If it's not possible to allow ssh from the dashboard why do we have that option?

SSH allows root user login by default. Is there an option to map users to their logged-in Net Bird user so that they are not allowed to log in as other users? (the users will be manually created on those servers.)

@jakob1379 commented on GitHub (Jan 16, 2025):

for me the issue was that my netbird config is not at the default location, but for some reason the location is not pulled from the daemon.

This means I have to do

sudo netbird -c path/to/config ssh my-remote
# or alternatively
export NETBIRD_CONFIG=path/to/config
sudo -E netbird ssh my-remote
