Use of a different SSH port.

[SimonLefort]

Describe the bug

If I change the default SSH port, Borg didn't work anymore (pretty normal). I change in the configuration file but I am not sure it's the best way to correct it.

Context

• Hardware: VPS online
• YunoHost version: 4.3.4.2 (stable)
• I have access to my server: Through SSH and through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: yes
  • If yes, please explain: I changed the SSH port
• Using, or trying to install package version/branch: Everything is up-to-date

Steps to reproduce

Change the SSH default port (22) on the server who hold the backup.

Expected behavior

I change the configuration in the borg app configuration file :

# vim /etc/yunohost/hooks.d/backup_method/05-borg_app
if ssh-keygen -F "myserver.com" >/dev/null ; then
    #BORG_RSH="ssh -i /root/.ssh/id_${app}_ed25519 -oStrictHostKeyChecking=yes "
    BORG_RSH="ssh -i /root/.ssh/id_${app}_ed25519 -p 1234 -oStrictHostKeyChecking=yes "
else
    #BORG_RSH="ssh -i /root/.ssh/id_${app}_ed25519 -oStrictHostKeyChecking=no "
    BORG_RSH="ssh -i /root/.ssh/id_${app}_ed25519 -p 1234 -oStrictHostKeyChecking=no "
fi

I works but I am not sure it's the best place to write the change. What do you think ?

Logs

Before I add the port in _/etc/yunohost/hooks.d/backup_method/05-borgapp :

# tail -n 100 /var/log/backup_borg.err
[2021-12-19_00:06:40] Remote: ssh: connect to host myserver.com port 22: Connection refused
[2021-12-19_00:06:40] Connection closed by remote host. Is borg working on the server?

Thank you for reading.

I close this bug cause the borgserver app is not concerned by that (borg_ynh partially yes)
