7. ESET Security system update

7.1 ESETS update utility

To maintain the effectiveness of ESET File Security, the virus signature database must be kept up to date. The esets_update
utility has been developed for this purpose. See the esets_upda te(8 ) man page for details. To launch an update, the configuration
options 'a v_upda te_userna me' and 'a v_upda te_pa ssword' must be defined in the [g loba l] section of the ESETS configuration file.
In the event that your server accesses the Internet via HTTP proxy, the additional configuration options 'proxy_a ddr' , 'proxy_port'
must be defined. If access to the HTTP proxy requires a username and password, the 'proxy_userna me' and 'proxy_pa ssword'
options must also be defined in this section. To initiate an update, enter the following command:
@SBINDIR@/esets_update
To provide the highest possible security for the end user, the ESET team continuously collects virus definitions from all over
the world - new patterns are added to the virus signature database in very short intervals. For this reason, we recommend that
updates be initiated on a regular basis. To specify the update frequency, the 'a v_upda te_period' option must be defined in the
[g loba l] section of the ESETS configuration file. The ESETS daemon must be up and running in order to successfully update the
virus signature database.

7.2 ESETS update process description

The update process consists of two stages: First, the precompiled update modules are downloaded from the ESET server. If the
option 'a v_mirror_ena bled' is set to 'yes' in the [g loba l] section of the ESETS configuration file, copies (or mirror) of these update
modules are created in the following directory:
@BASEDIR@/mirror
If desired, the Mirror directory path can be redefined using the 'a v_mirror_dir' option in the [g loba l] section of the ESETS
configuration file. The newly created Mirror can then serve as a fully functional update server and can be used to create lower
(child) Mirror servers. See section 7.3 for details.
The option 'a v_mirror_pcu' allows you to download Program Component Update (PCU) modules for Windows-based ESET
security products. These modules can be mirrored from the ESET server.
NOTE: Once you set your username, password and license for ESET File Security to download PCU's for ESET NOD32 Antivirus /
ESET Smart Security, please contact our Technical Support and request a change, that will enable your ESET File Security to
download PCU's for our Windows-based products.
The second stage of the update process is the compilation of modules loadable by the ESET File Security scanner from those
stored in the local mirror. Typically, the following ESETS loading modules are created: loader module (em000.dat), scanner
module (em001.dat), virus signature database module (em002.dat), archives support module (em003.dat), advanced heuristics
module (em004.dat), etc. The modules are created in the following directory:
@BASEDIR@
This is the directory where the ESETS daemon loads modules from and thus can be redefined using the 'ba se_dir' option in the
[g loba l] section of the ESETS configuration file.

7.3 ESETS mirror http daemon

ESETS mirror http daemon is installed automatically with ESET File Security. The http mirror daemon starts if the option
'a v_mirror_httpd_ena bled' in the [g loba l] section of the ESETS configuration file is set to 'yes' and the Mirror is enabled.
Options 'a v_mirror_httpd_port' and 'a v_mirror_httpd_a ddr' define the port (default 2221) and address (default: all local tcp
addresses) where the http server listens.
The option 'a v_mirror_httpd_a uth_mode' allows access authentication (default: none) to be changed to basic. The options
'a v_mirror_httpd_userna me' and 'a v_mirror_httpd_pa ssword' allow an administrator to define the login and password used to
access the Mirror.
