Virus Scanner

We have a site license for Network Associates scanner; it's downloaded from http://sdownload.nai.com/products/PROTECTED/virusscan/english/cmdline/bsd/v4.32/vbsd432l.tar.Z

Download and install it as follows:

cd /tmp
wget http://sdownload.nai.com/products/PROTECTED/virusscan/english/cmdline/bsd/v4.32/vbsd432l.tar.Z
tar xvf vbsd4321.tar.z
./install-uvscan
/usr/local/uvscan/uvscan

The final line will test the installation; it may fail with a missing library. I created /etc/libmap.conf and added the following lines:

libm.so.2 libm.so.3
libc.so.3 libc.so.5

This tells the system to use the second named library when asked for the first; check in /lib to see which libraries you have

You need to make sure the virus definitions are updated regularly - http://www.sng.ecs.soton.ac.uk/mailscanner/serve/cache/111.html has a script which can be used. Save it as /usr/local/uvscan/update.sh and then

chmod 755 /usr/local/uvscan/update.sh

so that it can be executed from cron

Need to configure /usr/local/etc/MailScanner/MailScanner.conf so that it uses this virus scanner. There's also a virusscanners.conf file which contains details of where the scanner is installed - if you use the default location then you don't need to change that file.
