Re: [TCLUG:22365] Hacked

[Brian <tobytoo@black-hole.com>]

the xferlog is clean, as in empty, and the secure log has no mention of a
pbadmin logging in since i reinstalled on the 5th..
 Do you have the url for CERT?
   I should mentionthat my mobo is going wonky on me too. the battery that
holds the cmos is dead from the looks of it, it keeps defaulting my bios, but
that only started after i shut down this afternoon.
where do i find my bind version?
