"What tells it that it is a "scan" service? That bit of the puzzle seems to be missing..."
Whatever is the parameter after the @ and before the dot becomes %i in the service file. Look at the service file: [Unit] Description = clamd scanner (%i) daemon After = syslog.target nss-lookup.target network.target
[Service] Type = simple ExecStart = /usr/sbin/clamd -c /etc/clamd.d/%i.conf --nofork=yes Restart = on-failure PrivateTmp = true
so clamd@scan.service invokes clamd with the scan.conf file as it's configuration file. This way you can have multiple clamd services each using a different config file. Just create another config file in /etc/clamd.d/my_config.conf and: ln -s /lib/systemd/system/clamd@.service /etc/systemd/system/clamd@my_config.service
You should have the /etc/clamd.d/scan.conf I think:
[root@moses shorewall]# rpm -qf /etc/clamd.d/scan.conf clamav-scanner-0.97.5-1700.fc17.noarch
Thank you Bill for a helpful and, more importantly, informative reply. I think this will not only help me to solve my problem but, even better, help me to understand where I was going wrong.
As before, I don't have access to the machine right now, so i will try when I get home to work through this and get it right.
I will once again report back later...
Thanks again. Your help is much appreciated.

You mentioned scanning email. I run clamav-milter and stop the virus at smtp time. You may find this helpful:
[root@moses clamav]# rpm -qa | grep clam | sort clamav-data-0.97.5-1700.fc17.noarch clamav-filesystem-0.97.5-1700.fc17.noarch clamav-lib-0.97.5-1700.fc17.x86_64 clamav-milter-0.97.5-1700.fc17.x86_64 clamav-milter-systemd-0.97.5-1700.fc17.noarch clamav-scanner-0.97.5-1700.fc17.noarch clamav-scanner-systemd-0.97.5-1700.fc17.noarch clamav-server-0.97.5-1700.fc17.x86_64 clamav-server-systemd-0.97.5-1700.fc17.noarch clamav-update-0.97.5-1700.fc17.x86_64
For clamav-milter, I had to add clamilt to the postfix group (usermod -a -G postfix clamilt): [root@moses clamav]# egrep 'post|clam' /etc/group mail:x:12:postfix postfix:x:89:clamilt postdrop:x:90: clamscan:x:987:clamilt clamilt:x:988:postfix clamupdate:x:989:
Add to the end of /etc/mail/clamav-milter.conf: # my stuff # be sure to comment out above: Example

OnInfected Reject AddHeader Replace
#LogFile /var/log/clamav-milter.log #LogFileMaxSize 1M #LogTime yes LogSyslog yes LogFacility LOG_MAIL #LogVerbose no LogClean Basic LogInfected Full
Add to postfix's main.cf: # usermod -a -G clamilt postfix smtpd_milters = unix:/var/run/clamav-milter/clamav-milter.socket #milter_default_action = accept milter_default_action = tempfail
I can't remember if I had to create the directory, but here is that info: [root@moses clamav]# ldpz /var/run/clamav-milter/clamav-milter.socket drwxr-xr-x. root root system_u:object_r:var_t:s0 /var lrwxrwxrwx. root root system_u:object_r:var_run_t:s0 /var/run -> ../run drwx--x---. clamilt clamilt system_u:object_r:clamd_var_run_t:s0 /var/run/clamav-milter srw-rw----. clamilt postfix system_u:object_r:clamd_var_run_t:s0 /var/run/clamav-milter/clamav-milter.socket
For clamav, to avoid selinux problems issue command: setsebool -P clamd_use_jit on
Add to end of scan.conf: # my stuff # be sure to commend out above: Example
#LogFile /var/log/clamav/clamd.scan #LogFacility LOG_MAIL LogFacility LOG_DAEMON ExtendedDetectionInfo yes LocalSocket /var/run/clamd.scan/clamd.sock #LocalSocketGroup virusgroup #LocalSocketMode 660 FixStaleSocket yes CrossFilesystems no ExcludePath ^/proc/ ExcludePath ^/sys/ ExcludePath ^/fuse/ ExcludePath ^/backup/ ExcludePath ^/bacula/ SelfCheck 3600
And finally freshclam, add to the end of freshclam.conf: # my stuff LogFacility LOG_DAEMON DatabaseMirror db.US.clamav.net TestDatabases yes
Note in all the clamav configuration file there is a line: Example that has to be commented out for the service to run.
Don't forget to systemctl enable these to services: [root@moses clamav]# systemctl is-active clamav-milter.service active [root@moses clamav]# systemctl is-active clamd@scan.service active
Hope this helps, Bill
Is this the default setting for clamd now? clamd_use_jit on Should we turn this on by default? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/

I can't speak for everyone else, but with my setup, I was getting selinux errors with clamd. When I ran audit2allow it said to set this boolean to eliminate the errors.
