AvpLinux and antiviral database update v0.7

Русская версия

What is it

AvpUpdate is a program for automated updating of antiviral database via network.

AvpUpdate allows to compare local antiviral database and antiviral database on Support-server and if it is necessary to update. AvpUpdate can run the external program if local database was successfully updated. For instance, this external program can send an announcement of new update to your colleagues. If antiviral database is successfully updated or if no update is needed, AvpUpdate will terminate with exit code 0.

Installation

Uncompress and unpack the distribution 

tar zxvf AvpUpdate-0.6.tar.gz

Copy file AvpUpdate into /usr/sbin.

I recommend to use cron utility to run AvpUpdate. For example to start AvpUpdate on 1:00 daily one can put into the file /var/spool/cron/root this string: 

0 1 * * * /usr/sbin/AvpUpdate
Use "man crond" and "man crontab" for references.
If you have dial-up connection to Internet is used the start-up of the Avp-Update can be put in file /etc/ppp/ip-up.local.

AvpUpdate is written on Perl Language and it is required perl-library Bundle::libnet. This library may be installed by command (root privelege and Internet access are required): 

# perl -MCPAN -e shell
...
cpan> install Bundle::libnet
...
cpan> exit
#
