[clamav-users] Clam user has read permissions, but I still get "lstat() failed: Permission denied"

[SCOTT PACKARD]

You'd want to:
ls -ld /
ls -ld /var
ls -ld /var/www
l s-ld /var/www/nc_data
and make sure user www-data has at least read and execute permissions to the parent directories.
You probably have removed read and execute from other, so clamdscan can't go down in the
directory hierarchy to get to /var/www/nc_data/.

Regards, Scott

Hi all,
 For some reason, clamdscan is returning a permissions error for files it has read access to.
I've copied some output below to help show the situation...

==============================================
root at arquivos0:/var/www# grep User /etc/clamav/clamd.conf

To quote Aristotle, "WTF?"

Any help appreciated!
