Hi,
I'm refering that on a dead filesystem witch is the best tool to check if there is any rootkit.

I do not want to check listening ports because it would check the wrong machine.

The best tool for that is nmap (or for the GUI users, nmap-fe).

Maybe a combination of chkrootkit -d with some AV? Any recomendation?

Thanks,
Jordi

About this discussion, chkrootkit are for live systems, isn't it?
There's any tool to do rootkit analysis on a "dead" system?

I'm thinking of check for rootkits on snapshots of the file system of a
virtual machine to determine if the running virtual machine is compromised.

Use -r switch? As long as you can mount the dead system as a (possbily
ro) filesystem, I don't see why not.
