It is recommended to use the Updater script (update.pl) to update virus databases. Updater is a part of Dr.Web for Kerio MailServer and can be installed via the drweb-updater packet of the installation archive.
|
In case Dr.Web Agent operates in the Enterprise mode, virus databases and anti-virus engine are updated from the repository of Dr.Web Control Center. |
The Updater script is written in Perl and is located in the directory of executable files of application (by default, /opt/drweb/update.pl). Updater settings are specified in the [Updater] section of the main configuration file (by default, /etc/drweb/drweb32.ini). To use a different configuration file, it is necessary to specify the full path to it via command line parameter when launching the script.
When installing the drweb-updater packet, a task for periodic launch of the update.pl script (every half an hour) is created via a standard scheduler (cron). This is done by creating the drweb-update file in the /etc/cron.d directory. The file contains the following code:
*/30 * * * * drweb /opt/drweb/update.pl
The [Updater] section of the configuration file contains the following parameters:
