Quit epossibly you haven't removed his backdoor. When people hack into
your site, it's prudent to check all files that are setuid root, and also
check your kernel -- when was it last updated, and has your vmlinuz file
changed in size.
Maybe it'll teach you to use something like tripwire, to prevent this kind
of stuff.

Some people have told me they don't think a fat penguin really embodies
the grace of Linux, which just tells me they have never seen a angry
penguin charging at them in excess of 100mph. They'd be a lot more
careful about what they say if they had.
