which port does secure shell run on?

We need to figure out which port to open up on the firewall to allow shell access to our new Linux box--is it port 22?

Now, back in school I remember using Secure Shell, but you pay for that in the non-academic world, right? Is the default thing that comes with Red Hat 8 most likely secure enough?

Yes, it runs on port 22. OpenSSH is fairly secure, and totally free, btw. Also, meet /etc/services, it is a good resource for determining the default ports for many various protocols. Simply "grep $servicename /etc/services" for the answer.
