Clamav errors on upgrade to 0.96 clamd and clamav-milter

Some updates to the yum-sent clamav-milter.conf and (to a lesser extent) clamd.conf may be necessary.

After an automatic yum-update of the clamd family on RHEL, there’s a disparity in the way clamav-milter listens and clamd services the socket or port connection — clamav-milter doesn’t know what to go with (local socket on unix:/tmp/clamav.socket or tcp: – so you need to tell it. Otherwise, you get messages such as the below in you clamav-milter.log:

clamav-milter[5149]: No clamd server appears to be available
ERROR: Failed to initiate streaming/fdpassing

So make sure the ClamdSocket in clamav-milter.conf points to the LocalSocket that clamd.conf says it’s broadcasting on. So if clamd.conf is

LocalSocket /tmp/clamd.socket

clamav-milter.conf should have

ClamdSocket unix:/tmp/clamd.socket

Else, if you’re on LocalSocket on on the default port, just set ClamdSocket as below:

ClamdSocket tcp:

Also, be sure to do an sa-update

Simple, eh? But you knew that already! 🙂
