Does someone knows what is the best possible way to run a 2nd SSH as instance/service on a different port so that it can be used with OMV and will be usable through upgrades?
I want to have an alternative SSH service to my system only accessible through public key. This config is no issue, but I need to know how I can add this 2nd SSH service the easiest..
the purpose is:
I have a mail in a box device running which needs to rsync over SSH, I do not want to use my normal SSH as this is accessible through password (and public key) but I only want to allow password through local network and not from the dark wild outside world. therefor the public key part.
