Fortinet 138 FortiWeb 5.0 Patch 6 Administration Guide
4. Click Apply.
5. Click Update Now.
The FortiWeb appliance tests the connection to the FDN and, if any, the server you specified
to override the default FDN server. Time required varies by the speed of the FortiWeb
appliance’s network connection, and by the number of timeouts that occur before the
connection attempt is successful or the FortiWeb appliance determines that it cannot
connect. If you have enabled logging in:
•Log & Report > Log Config > Other Log Settings
•Log & Report > Log Config > Global Log Settings
test results are indicated in Log & Report > Log Access > Event. If the connection test did
not succeed due to license issues, you would instead see this log message:
FortiWeb is unauthorized
For more troubleshooting information, enter the commands:
diagnose debug enable
diagnose debug application fds 8
This will cause additional information to be output to your CLI console, such as:
FortiWeb # [update]: Poll timeout.
FortiWeb # *ATTENTION*: license registration status changed to
'VALID',please logout and re-login
For example, poll (license and update request) timeouts can be caused by incorrectly
configured static routes and DNS settings, links with high packet loss, and other basic
connectivity issues. Unless you override the behavior with a specific FDS address (enable
and configure Use override server address), FortiWeb appliances connect to the FDN by
connecting to the server nearest to the FortiWeb appliance by its configured time zone.
Timeouts can therefore also be caused by incorrect time zone.

Choosing the virus signature database & decompression buffer
Most viruses are actively spreading initially, but as hosts are patched and more networks filter
them out, their occurrence becomes more rare.
Fortinet’s FortiGuard Global Security Research Team continuously monitor detections of new
and older viruses. When a specific virus has not been detected for one year, it is considered to
be dormant. It is possible that a new outbreak could revive it, but that is increasingly unlikely as
time passes due to replacement of vulnerable hardware and patching of vulnerable software.
Therefore dormant viruses’s signatures are removed from the “Regular” database, but
preserved in the “Extended” signature database.
