Yea, turn off, or uninstall ssh. Do not under any circumstances change the root password! If you do, you get to play the restore the bricked iPhone game. It's not fun, and sometimes not possible. The password is hard coded into some applications that need to use it, springboard (the gui) is one of them. If you change the password, you get an endless welcome to your new iPhone screen loop. This is one of the reasons they don't want people screwing with the phones. If they don't know what ssh it they need to stay the hell out of the iPhone's innards!
