2.1.9. Working with Configurations Chapter 2. Management and Maintenance Example 2.9. Listing Modified Configuration Objects This example shows how to list configuration objects that have been modified. Command-Line Interface gw-world:/> show -changes Type Object - IP4Address myhost * ServiceTCPUDP telnet A "+" character in front of the row indicates that the object has been added. A "*" character indicates that the object has been modified. A "-" character indicates that the object has been marked for deletion. Web Interface 1. Go to: Configuration > View Changes in the menu bar A list of changes is displayed Activating and Committing a Configuration After changes to a configuration have been made, the configuration has to be activated for those changes to have an impact on the running system. During the activation process, the new proposed configuration is validated and NetDefendOS will attempt to initialize affected subsystems with the new configuration data. Important: Committing IPsec Changes The administrator should be aware that if any changes that affect the configurations of live IPsec tunnels are committed, then those live tunnels connections will be terminated and must be re-established. If the new configuration is validated, NetDefendOS will wait for a short period (30 seconds by default) during which a connection to the administrator must be re-established. As described previously, if the configuration was activated via the CLI with the activate command then a commit command must be issued within that period. If a lost connection could not be re-established or if the commit command was not issued, then NetDefendOS will revert to using the previous configuration. This is a fail-safe mechanism and, amongst others things, can help prevent a remote administrator from locking themselves out. Example 2.10. Activating and Committing a Configuration This example shows how to activate and commit a new configuration. Command-Line Interface gw-world:/> activate The system will validate and start using the new configuration. When the command prompt is shown again: gw-world:/> commit The new configuration is now committed. Web Interface 1. Go to: Configuration > Save and Activate in the menu bar 57
