when changing the ssh port number just be careful to not lock yourself by ufw (enable that port before changing the sshd config file)

New subscriber here! I realize this video is dated however, I'm just starting to learn about home labbing and this was a great video, with a great instructor! I learned things! ...and took notes. One thing I want to do is provide movie streaming for my disabled neighbor who is on a low fixed income with stage 4 RA to be able to have a way to watch movies, especially over the long winter months. This is going to require my eventual media server to be accessible off premises. I've acquired a HUGE assortment of dvd's from a pawn shop that closed down. Security is going to be a must.

Quick tip make sure before switching your port to allow the port. I ran into an issue where my firewall was blocking my assigned port number. Use this command to allow/enable it - sudo ufw allow PORT_NUMBER

To access your remote server, you'll most likely need to use SSH.
