        SSH on port 3232 and 5252. Secure Shell (SSH) is a protocol for logging
        into and executing commands on remote machines. It provides secure
        encrypted communications. If you plan on accessing your machine
        remotely via SSH over a firewalled interface, enable this option. You
        need the openssh-server package installed for this option to be useful.
