I am having a problem getting sshd to run after changing it's default port. I edit sshd_config and set the desired port, open it with firewall-cmd and then issue a systemctl start sshd. No error gets reported on the console but the following is logged in /var/messages

sshd.service: main process exited, code=exited, status=255/n/a

Not a very helpful error message. Sounds like I should report a bug?

If you have SELinux enabled, it will block sshd from listening on a port other than what is described in the policy. You can add the additional port by running:

semanage port -a -t ssh_port_t -p tcp $PORTNUM

(replace $PORTNUM with the new port number you chose)
