Chapter 6. NOD32 system update and maintenance
that has to be adjusted by the user. The authorization file is an ASCII file with the following
format.
username=your_nod32_username
password=your_nod32_password
Please, use your favorite editor to invoke the file and fill its appropriate parts by valid username
and password that you have received from your vendor.
From the security reason make sure that the authorization file is publicly unreadable. If it is not
the case change its permission appropriately by typing
chmod 600 /etc/nod32/nod32.auth
into the command line.
6.3.2. Periodic update of the virus definitions database
To provide the highest security for the user, the NOD32 team collects the virus definitions con-
tinuously from all over the world. The new patterns can appear within the database in very
short intervals. It is therefore useful, and also recommended, to trigger an update attempt (by
means of executing the nod32_update script) on a regular basis via periodic scheduler. One hour
interval is recommended. In order to do so, configure periodic scheduler (cron) on your system
by entering the following line
0 * * * * /usr/sbin/nod32_update
into its configuration file (crontab). To add the above line into the crontab use command line
statement
crontab -e
that will invoke the editor set up for the current system environment (defined by EDITOR envi-
ronment variable).
