avgd stops listening on port 54322

Last days I’m experiencing avgd not responding. Avgd stops to listen on port 54322, amavisd-new timeouts on talking to AV. Mails are being held and queue is slowly increasing its number. It’s strange, that I’m experiencing it not only on one production system…

Aug 29 04:59:46 rakosnicek amavis[25940]: (25940-01-5) (!)AVG Anti-Virus av-scanner FAILED: run_av error: Too many retries to talk to 127.0.0.1:54322 (timed
out) at (eval 111) line 373.\n

It seems working after changing a little bit AVG configuration with following values:

avgcfgctl -w Default.setup.features.antispam=false
avgcfgctl -w Default.tcpd.avg.limiter_start=150
avgcfgctl -w Default.tcpd.avg.limiter_stop=200
avgcfgctl -w Default.tcpd.avg.timeout=5000
avgcfgctl -w Default.tcpd.smtp.enabled=false
avgctl --restart=tcpd

Zoner Antivirus with Amavisd-new

Today I have decided to test Amavisd-new with free Zoner Antivirus for Linux. First of all you have to download the package, (test it), install, and change the ownership. Then edit the configuration.

wget http://update.zonerantivirus.com/download/zav-1.2.2-redhat-i586.rpm --nodeps
rpm -Uhv zav-1.2.2-redhat-i586.rpm --test
rpm -Uhv zav-1.2.2-redhat-i586.rpm
chown amavis: /opt/zav -R
chown amavis: /var/run/zav -R
vi /etc/zav/zavd.conf

So, we have changed the ownership. Now we have to change the daemon user to amavis too.

# user under which to run the daemon
ZAVD_USER               = "amavis"
ZAVD_GROUP              = "amavis"
# Your license key for accessing ZAV update
UPDATE_KEY              = "11111-22222-SAMPLE-33333-44444"

We can start and update ZAV with:

/etc/init.d/zavd start
/etc/init.d/zavd update

Finally we have to change Amavisd-new configuration by adding the following:

 ### http://www.grisoft.com/
 ['Zoner Anti-Virus',
#  '/opt/zav/bin/zavcli', '-z /var/run/zav/zavd.sock {}',
  '/opt/zav/bin/zavcli', ' {}',
  [0,1,2,3,4], [5,6,7,11],
  qr/^.*:\ (SUSPICIOUS|PROBINFECTED|INFECTED)\ \((.*)\)$/
]

AVG 8.5 with Amavisd-new

Amavisd-new is a quite powerful tool capable to co-operate with a large amount of AV scanners. Today I have decided to test it with free AVG Antivirus for Linux. First of all you have to download the package, (test it), install, and change the ownership. Then edit the configuration.

wget http://download.avgfree.com/filedir/inst/avg85flx-r287-a2632.i386.rpm
rpm -Uhv avg85flx-r287-a2632.i386.rpm --test
rpm -Uhv avg85flx-r287-a2632.i386.rpm
chown amavis: /opt/avg -R
vi /opt/avg/avg8/etc/init.d/avgdinit.conf

So, we have changed the ownership. Now we have to change the daemon user to amavis too.

# user under which to run the daemon
SUSER=amavis

We can start AVG with:

/etc/init.d/avgd start

Finally we have to change Amavisd-new configuration by commenting out  AVG section and changing the port:

 ### http://www.grisoft.com/
 ['AVG Anti-Virus',
   \&ask_daemon, ["SCAN {}\n", '127.0.0.1:54322'],
   qr/^200/, qr/^403/, qr/^403 .*?: ([^\r\n]+)/ ],
