Original GitHub issue: https://github.com/netbirdio/netbird/issues/5009

Describe the problem

It is unclear how to disable the SSH server once enabled on Linux systems. (For Windows it is clear, though.)

To Reproduce

Steps to reproduce the behavior:

Create NetBird SSH Policy e.g., 'all to all Full Access'
On a Linux system run netbird down && netbird up --allow-server-ssh --enable-ssh-root
netbird ssh ubuntu@monitor.anon-QyPf0.domain from another machine works
Now I want to disable SSH Server again. But how?

netbird down && netbird up --allow-server-ssh false --enable-ssh-root false has no effect
also one might expect netbird down && netbird up to work

Expected behavior

A clear option in the command shell to undo the changes from netbird down && netbird up --allow-server-ssh --enable-ssh-root.
Additionally:

Why do I need to restart netbird by down & up? Why is there no netbird set <flag>?

Are you using NetBird Cloud?

Self-host NetBird's control plane.

NetBird version

0.61.0

Is any other VPN software installed?

No

Hey @lorenzbaum,

Try the command below. We will update our docs to make it clearer.

netbird down && netbird up --allow-server-ssh=false
