I am about to configure firewall with UFW. I am logged in over SSH so I don't know if the terminal will be locked out as soon as I do:



 sudo ufw default deny incoming


If so, how can I deny all incoming (lock the whole thing down) except SSH and do it all in the same command?

          In my experience, despite the warnings, enabling UFW does not lock out the current session. By default, UFW will block all incoming. To allow SSH, use:



          sudo ufw allow OpenSSH


          You can also use the limit option (note that port 22 is the default SSH port):



          sudo ufw limit 22/tcp


          To enable UFW use:



          sudo ufw enable

            You can also use the at command to issue a "sudo disable UFW" at +5 minutes, so if you do get locked out, you can wait 5 minutes, and be allowed back in ;)
