Yet anothe r"have i been hacked" alert

["Andreas Vitz" <k-egg@gmx.de>]

Hi there,
I'm knew to the program called logchecker and today i got following
message:

kai-router 2003/05/15 23:02 ACTIVE SYSTEM ATTACK!

Cleaned rules files exist in /var/lib/logcheck/cleaned directory that
cannot be removed. This may be an attempt to spoof the log checker.


i don't understand what this  message means. and i dont fing good
how-to's, documentations or
stuff like this about warnings caused by logcheck




there are some other suspicious (to me) log entries:
