Clamav: troubleshooting of clamdscan
clamdscan is much faster to run than
clamscan, however, it requires
clamd which is a bit harder to setup, so I have some tips for troubleshooting:
ERROR: Could not lookup : Servname not supported for ai_socktype
Usually you should check the permission, especially whether the current user is in group
clamscan (the primary group of the clamd running user).
lstat() failed: Permission denied. ERROR
This is usually because
clamd running does not have the permission to run the is run as non-root user.
So you will need to enlist User
clamscan (the user that runs
clamd). You need to logout and login to make that change effective.
If it is still failed with the same error messsage, it is still possible that you are fooled by ACL permission. Use
getfact to check it. The reason? When you
ls, you get:
drwxr-xr-x+ 2 testuser testuser 40 Jul 17 15:19 /tmp/test
But your actual ACL (
getfacl /tmp/test)might look like:
getfacl: Removing leading '/' from absolute path names
# file: tmp/test
# owner: testuser
# group: testuer
