[Bug 708395] Re: clamdscan can't scan anything

[Andrew]

Thanks for the link, JG.

I didn't realize running clamdscan as root would cause problems.  I did
that in all my tests to try to alleviate any permissions issues.  I'll
make sure I run all my tests as a regular user from now on.

In the first test, clamdscan works on my machine as well.  When I make
the file in /tmp 640, however, I receive a different error message:

----------------------------------
/tmp/eicar.com.txt: Access denied. ERROR
----------------------------------

This is different from the lstat() error I receive in every other case.
/tmp/ appears to be a special case.  I need to scan other directories...

Also, when I tried adding clamav to my user's group, it appeared to
work, but I got more errors when restarting the daemon followed by the
same "Access denied" error:
