I’m evaluating the AVG 8.5 free Edition for Linux on Centos 5. It’s fairly easy step to setup. Just download the installer, install, update virus definition database.tweak some avgtcpd’s config and voila!! it’s running smoothly. Here’s the step everyone might want to know.
Download avg 8.5 installer
$ wget -t0 -c http://download.avgfree.com/filedir/inst/avg85flx-r863-a3205.i386.rpm
Install
$ sudo rpm -ivh avg85flx-r863-a3205.i386.rpm
start the service (in this case i was using init.d script)
$ sudo /etc/init.d/avgd start
Verify if avgtcpd is running
$ sudo netstat -pltn | grep avgtcpd tcp 0 0 127.0.0.1:54321 0.0.0.0:* LISTEN 10839/avgtcpd tcp 0 0 127.0.0.1:54322 0.0.0.0:* LISTEN 10839/avgtcpd
Update virus definition database
$ sudo avgupdate
By default avgtcpd limiting tcpd listener, we need to raise maximum connection avgtcpd can handle.
here’s the default setting:
$ sudo avgcfgctl Default.tcpd.avg.limiter_start AVG command line avgcfgctl Copyright (c) 2010 AVG Technologies CZ Default.tcpd.avg.limiter_start=20 $ sudo avgcfgctl Default.tcpd.avg.limiter_stop AVG command line avgcfgctl Copyright (c) 2010 AVG Technologies CZ Default.tcpd.avg.limiter_stop=25
Set to reasonable value for the server.
$ sudo avgcfgctl -w Default.setup.features.antispam=false $ sudo avgcfgctl -w Default.tcpd.avg.limiter_start=150 $ sudo avgcfgctl -w Default.tcpd.avg.limiter_stop=1024 $ sudo avgcfgctl -w Default.tcpd.avg.timeout=5000
Restart tcpd
$ sudo avgctl --restart=tcpd
Now in amavisd-new part, edit amavisd-new configuration, add this av scanner setting for AVG.
['AVG Anti-Virus',
&ask_daemon, ["SCAN {}n", '127.0.0.1:54322'],
qr/^200/, qr/^403/, qr/^403 .*?: ([^rn]+)/ ],
Restart amavisd-new service
$ sudo /etc/init.d/amavisd restart
amavisd-new with avg is ready!
