If its a pristine rh7.0 install, that version of bind has a notorious rootkit hole. So I wonder if the machine has been kitted by some script kiddie whose good at covering his tracks but not the rest of the housekeeping. Do a google search for "chkrootkit", and install it to get a better view of that possibility.
An OS upgrade does seem to be in order, lots has happened since 7.0. 7.3 with an updated kernel is my firewall, uptime is about 95 days now. It was shut down while I was out of state for a couple of months last fall. RH8.0 on this machine, with the real KDE-3.1.1a, but since RH is gonna force a switch, debian may be the next thing installed here. Or maybe Mepis since he's only 50 miles up the interstate from me. :)
