i recently decided to turn my old desktop pc into a linux server where i can host my files etc. I followed a tutorial which used openssh and after installing it and configuring some files it works like a charm. I have a few questions though: the tutorial i followed here uses nc -v -z [addr] [port] to check if the ssh service is working on that port. However, no matter which port i use in the sshd_config file, it won't successfully listen on that port. Any ideas why?
PS: i'm a complete beginner to linux :)
