In the same area of the Web-interface it is also possible to manually initiate updating by selecting
Update now to download the latest signatures to the database.
Note: Updating the database causes a pause in processing
Some database updates such as for anti-virus can require a brief processing delay once
an update is downloaded. This can cause the firewall traffic flow to momentarily pause.
It can therefore be best to set the timing of updates to be at times with minimal traffic,
such as in the early hours of the morning. Deleting a database can cause a similar pause
in processing.
Database Console Commands
Database updates can be controlled directly through a number of console commands and these
are listed below:
• Pre-empting Database Updates
An IDP database update can be forced at any time by using the command:
gw-world:/> updatecenter -update=idp
An Anti-Virus update can similarly be initiated with the command:
gw-world:/> updatecenter -update=antivirus
• Querying Update Status
To get the status of IDP updates use the command:
gw-world:/> updatecenter -status=idp
To get the status of AV updates:
gw-world:/> updatecenter -status=antivirus
• Querying Server Status
To get the status of the D-Link network servers use the command:
gw-world:/> updatecenter -servers
This command shows the following information for all available servers:
i. Server IP - The IPv4 address of the server.
ii. Response time - The current response time in milliseconds from a test communication
with each server.
iii. Packet loss - The packet loss seen in the test for that server.
iv. Precedence - One server will be designated as Primary and the others Backup. The
Primary will always be the one used for downloads to NetDefendOS. If it becomes
unavailable, one of the backup servers will become the primary.
