2.7.1. Version Update Alerts
Overview
NetDefendOS can optionally receive information from D-Link servers related to available
upgrades. This information is displayed to the administrator as alerts in the Web Interface. This
informs the administrator that upgrades are available. This feature is enabled by default and
must be disabled manually by the administrator, as shown in the example at the end of this
section.
When enabled, alerts of available upgrades appear only in the Alerts portion of the NetDefendOS
Web Interface toolbar.
Communication with D-Link Servers is Encrypted and Periodic
Communication between NetDefendOS and D-Link servers is encrypted and occurs at the
following times:
• Shortly after system startup.
• Once per day following startup.
Required Prerequisites
This feature will only function if all of the following are true:
• NetDefendOS has access to the public Internet.
• The feature has not been disabled by the administrator.
Log Event Message Generation
A log message is generated when an alert is generated for the administrator that version
upgrades are available. This message has a severity level of Notice and the log event name
new_firmware_available.
