sshd command

[irani74]

Hi,
I need to get a list of all clients connected to a Nebula network.
after reading issues, found #545 that answer my question
but I don't know how to run sshd in my CLI
Can anybody help me?

• generate a nebula ssh server key on the lighthouse:

cd /etc/nebula
ssh-keygen -t ed25519 -f ssh_host_ed25519_key -N "" < /dev/null

• generate a client key/pubkey:

ssh-keygen -f ssh_user.key

• configure sshd in the lighthouse's config.yaml:

sshd:
  enabled: true
  listen: 127.0.0.1:12222
  # A file containing the ssh host private key to use
  # A decent way to generate one: ssh-keygen -t ed25519 -f ssh_host_ed25519_key -N "" < /dev/null
  host_key: /etc/nebula/ssh_host_ed25519_key
  # A file containing a list of authorized public keys
  authorized_users:
    - user: root
      keys:
        # copy/paste the content of ssh_user.key.pub:
        - "ssh-rsa XXXXXXXXXXXXXXXXXXXXX"

• connect with ssh:

ssh -i ssh_user.key -p 12222 localhost list-hostmap
