NOTE:
In High Availability mode, you have to start the slave node through the IPMI interface. Failing to start the slave node results in a DEGRADED HA status. |
-
Navigate to Basic Settings > System > Version details and check the version numbers of SSB. In case you encounter problems, you can find common troubleshooting steps in Troubleshooting.
Troubleshooting
If you experience any strange behavior of the web interface, first try to reload the page by holding the Shift key while clicking the Reload button of your browser (or the F5 key on your keyboard) to remove any cached version of the page.
In the unlikely case that SSB encounters a problem during the upgrade process and cannot revert to its original state, SSB performs the following actions:
-
Initializes the network interfaces using the already configured IP addresses.
-
Enables SSH-access to SSB, unless SSB is running in sealed mode. That way it is possible to access the logs of the upgrade process that helps the our Support Team to diagnose and solve the problem. Note that SSH access will be enabled on every active interface, even if management access has not been enabled for the interface.
In case the web interface is not available within 30 minutes of rebooting SSB, check the information displayed on the local console and contact our Support Team.
Updating the SSB license
The SSB license must be updated before the existing license expires or when you purchase a new license. Information of the current license of SSB is displayed on the Basic Settings > System > License page. The following information is displayed:

-
Serial: The unique serial number of the license.
-
Host limit: The number of peers SSB accepts log messages from.
-
Valid: The period in which the license is valid. The dates are displayed in YYYY/MM/DD format.
SSB gives an automatic alert one week before the license expires. An alert is sent also when the number of peers exceeds 90% of the limit set in the license.
This section describes how to update the license.

-
To encrypt the configuration file with GPG, select GPG encryption. Note that this option uses the same GPG key that is used to encrypt automatic system backups, and is only available if you have uploaded the public part of a GPG key to SSB at Basic Settings > Management > System backup. For details, see Encrypting configuration backups with GPG.

Click Export.

NOTE:
The exported file is a gzip-compressed archive. On Windows platforms, it can be decompressed with common archive managers such as the free 7-Zip tool.
