Package: clamav-daemon
Version: 1.4.3+dfsg-1
Followup-For: Bug #1042377
Hi,
Thanks for the bug report.
I'm setting up an antivirus scanning server and I couldn't understand why clamav wasn't listening on the TCP socket.
I preferred to leave the TCPSocket option in the clamd configuration file to make it more readable and I mask the "clamav-daemon.socket" unit.
A hint about this behavior in the "/usr/share/doc/clamav-daemon/README.Debian.gz" file would be a plus.
Regards.
