Re: [Clamav-users] Problem with clamav on Linux

Linux distribution is: Redhat Linux 5.1 (Tikanga)
After set the SELinux on again to get the error log exactly. I received the error message when system start service clamd:
I can not remember exactly, but it means that clamd service can not open /var/log/clamav/clamd.log in append mode.
I'd just seen that this directory: /var/log/clamav is owned by root. I tried again by chown -R clamav:clamav /var/log/clamav, and restart again. Result is [OK], but clamd does not start actually.
This is the command result that you asked:
[root@home ~]# ls -IRZ /var/clamav
daily.inc main.cvd mirrors.dat
[root@home ~]#

PS. I had search "clamd" to find the error logs in both messages and audit.log.
