I use root to ssh into my linux box at home to do a port redirect so I can use 
xchat/IRC from the office. If I were to change PermitRootLogin to no, will 
that stop that?  Sounds like it. It's the only way I can use IRC from the 
office. I need to do it as root because a "normal" user can't do port 
redirects.
