I have a web server using rkhunter for rootkit protection.
When I check, rkhunter returns no warnings in the root kit part (so I guess I'm good). But I get a lot of warning when Performing file properties checks.
I figured out that this can be caused every time I update my system (apt-get dist-upgrade), because some files change during the update. Then rkhunter recognizes these changes.
After further research, I figured out that the option "--pkgmgr DPKG" should check against the latest values in the repository. So in theory (as far as I understood), it should return without warnings.
But it does not work and since I get an email as soon as rkhunter returns a warning I would like to know how to avoid these warnings.
