Virus Definition Updates
Overview of operations:
Updates virus definition files.
Updating may take some time because virus definition files are downloaded from the Internet.
You can specify proxy settings in
conf/dbupdate.conf.
Update process
The dbupdate command retrieves files from
http://fsbwserver.f-secure.com/
by using AUA (Automatic
Update Agent, “fsaua” command) and temporarily saves the files in the update directory. The files
are then copied to the “databases” directory.
If the virus definition files fail to download, check if the files can be downloaded from the following
URL:
http://fsbwserver.f-secure.com/
In addition, check the logs file (/opt/f-secure/fsigk/log/dbupdate.log, /opt/f-secure/fsigk/log/fsaua.log) for
any problems.
The configured proxy information is stored in /opt/f-secure/fsigk/conf/dbupdate.conf with the
following information:
use_proxy=[yes|no] Specifies whether the proxy is used or not
http_proxy_host= Specifies the host name of the proxy server
http_proxy_port= Specifies the port number of the proxy server
http_proxyauth= Specifies whether proxy authorization is used or not
http_proxyauth_user= Specifies the user name which is used for proxy authorization
http_proxyauth_pass= Specifies the password which is used for proxy authorization
To download virus definition databases from Policy Manager, specify “UPDATEURL=http://host
name:port number/” in /opt/f-secure/fsigk/conf/dbupdate.conf with the host name and port
number used by Policy Manager.
- You can check the version number of virus definition database files with “cd /opt/f-secure/fsigk;
make show-dbversion”.
The version number of database files for each engine (Aquarius,Hydra(FS-Engine)) corresponds
to "[Version]... File_set_visible_version=YYYY-MM-DD_XX" in
databases/aqulnx32/aquarius-linux-update.ini and databases/fse/[email protected]. The version
number of the entire virus definition file is determined by the highest version number among all of
the version numbers in each engine.
You can specify proxy settings in
conf/dbupdate.conf.
Command names:
/opt/f-secure/fsigk/dbupdate
Options:
--help
Displays a quick help which lists command-line options.
--auto
Definition files are not downloaded synchronously. Instead, the definition files
previously downloaded by F-Secure Automatic Update Agent are updated. This option
is used to fully automate virus definition updates.
