I am not running any backup software. I ran md5sum on my own workstation the firewall and a thrid mandrake 8.1 install that my housemate just installed yesterday night i did it as soon as he installed it so it's pretty much 99% trusted. And the md5sums came back the same each time. Rerunning results in the same warnings. And today i have a few more files also in /bin changed plus /etc/profile.d changed but no file /etc/profile.d has been changed. Again the new changes shows no differences in md5sum on any of the 3 linux boxes here. One of which is a trusted fresh install. So i dont' really know what's going on. Waht i want to ask is if it is possible that there is a on going disk failure and blocks are moving around and tripwire's detecting that? Cause that drive's about 3 years old and it's been up a long long time. thanks for the quick replies Sebastian Ip On Monday 15 October 2001 11:37, Berend De Schouwer wrote:

I woke up today checked my personal linux firewall logs.. noticed that over night tirpwire results were in my mail box.. Checked it.. and ALARM!! ls has been modified along with gunzip, gzip, zcat and cpio. All of them in /bin.Step 1: stay calm :) What changed? sums, permissions, or timestamps? If you run tripwire again, have the same files changed? If its different files, maybe you have flaky hardware.Thanks Sebastian Ip ------------------------------------------------------------------------- --- This list is provided by the SecurityFocus ARIS analyzer service.
