I understand. But since I was asked I thought maybe someone might see
something I didn't.

It has been to long since I ran chkrootkit, but... The only thing that
came up was:

Searching for suspicious files and dirs, it may take a while...
/usr/lib/perl5/5.6.0/i386-linux/.packlist

Searching for LPD Worm files and dirs... nothing found
...

it really does appear like a packing list, but has a bunch of files
which end in .3pm which have is about the time I typically notice odd
things going on. I assume that that is just a cooincidence since there
are files there that end in .tar.gz extention... Being in the man
directory I assumed that they are man pages, and the .gz being
gnuziped... One such example is:

/usr/share/man/man3/warnings::register.3pm type=file

I went ahead and tried looking at them and was unable with an of the
tools I expected, so does anyone have a clue what they should be for?
any Perl GURU's got an idea why they are not readable if they are
documentaiton?

My previous install I set up tripwire (had not heard about aide), but
have not taken the time because I have litterally been working 12-20
hr/days trying to finish up at school...
