Manual Update
Updates virus definition files to the latest version. Updating may take some time as the virus
definition databases are downloaded from the Internet.
Use the dbupdate command to update the definition file.
The dbupdate command retrieves files from
http://fsbwserver.f-secure.com/
using the AUA
(Automatic Update Agent, “fsaua” command), temporarily saves the files in the update directory,
and then copies the files to the “databases” directory.
If the virus definition databases fail to download, check if you can connect to the following URL:
http://fsbwserver.f-secure.com/
. A simple text message should be shown indicating that you
have reached the F-Secure Automatic Update Server.
In addition, check the log 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
use_proxyauth= Specifies whether proxy authorization is used or not
http_proxyauth_user= Specifies the user name used for proxy authorization
http_proxyauth_pass= Specifies the password used for proxy authorization
To download definition files from Policy Manager, specify UPDATEURL=http://<host
name>:<port number>/ in /opt/f-secure/fsigk/conf/dbupdate.conf.
- You can check the version number of virus definition files with
“cd /opt/f-secure/fsigk; make
show-dbversion”
.
You can obtain the version of the definition file for each engine (Aquarius, Hydra (FS-Engine))
from "[Version]... File_set_visible_version=YYYY-MM-DD_XX" in
databases/aqulnx32/aquarius-linux-update.txt and databases/fse/[email protected]. The overall
version of virus definition files is the highest version number amongst the versions of each
engine.
Automatic updates
Automatic Update
This function updates the definition file periodically (at hourly intervals).
Updates are performed by the crontab scheduler using the dbupdate command.
The dbupdate command retrieves files from
http://fsbwserver.f-secure.com/
by using the AUA
(Automatic Update Agent, “fsaua” command), temporarily saves the files in the update directory,
and then copies the files to the “databases” directory.
