Anyone know what I can do about these rkhunter warnings?

Warning: No output found from the lsmod command or the /proc/modules file:
/proc/modules output:
lsmod output:
Warning: The kernel modules directory '/lib/modules' is missing or empty.
Warning: Found passwordless account in shadow file: atomic

Hi,

The first two look like they're because you're running within Virtuozzo or OpenVZ, so just disable the checks in the rkhunter.conf .

The last one I haven't a clue on I'm afraid,

Paul.

You dont have a kernel, so you wont have any modules. You can ignore that (if thats true for you, which if its a virtual system it would be true)



That means you have given us access to the system and that account uses only keys to log in. You can ignore that.

Instead of ignoring it (which might be hard if rkhunter is e-mailing you about it every day) you can also disable the tests that check for kernel modules. You'll want to add 'avail_modules' and 'loaded_modules' to DISABLE_TESTS in /etc/rkhunter.conf or leave /etc/rkhunter.conf unmodified and override DISABLE_TESTS in /etc/rkhunter.conf.local (create that file if it doesn't exist yet).

Maybe ASL could disable these tests automatically if it detects a kernel without modules?

Sounds like a good idea.
