Hi.
On one of my servers aide just reported inode changes to a large bunch of files
in a variety of directories, e.g. /usr/bin, /usr/sbin etc. This machine sits
behind a couple of firewalls and it would be hard to get to.
The day before I updated "clam*" and updated the aide database right after that:
-rw------- 1 root root 7407412 Sep 26 10:58 aide.db.gz
The problem was that the changes were made when no-one was in the office, here
are a few:
Directory: /usr/sbin

I ran (a fresh install) of rkhunter, did not find a thing ...
Is it possible that a change to one file sets of a domino effect of indode
changes?
thanks
Jobst
