Master IP
In this field you insert the IP address for the interface on the master node, which is used
for the synchronisation between the master and backup. Normally the lan interface is
used.
Backup IP
In this field you insert the IP address for the interface on the backup node, which is
used for synchronisation between the master and backup. The IP addresses of master
and backup must be from the same address range.
Export public ssh-rsa key
Here you can download the public ssh-rsa key. Please import the key on the master,
otherwise the backup won't be able to update the master's configuration.
Temporary access to all settings
Gain access to all settings until you log out. All changes to otherwise unavailable
settings will be lost when the next synchronization with the backup node is performed.
Upload public ssh-rsa key
Here you import the public ssh-rsa key of the backup node.
Synchronize automatically
Configuration changes on the backup system must be propagated to the master. A
manual synchronization is started by clicking on "Update configuration on master".
Enable the automatic update to ensure that no one forgets this step.
We recommend to enable automatic synchronization at least
for user settings if users have access to the "My Account"
menu. As the Administrator never knows when a user changes
personal settings, this is the only way to guarantee their prompt
propagation.
Delay after last change
If set to "0", each configuration change immediately propagates to the master.
Otherwise the synchronization will be delayed until the configured period of time has
elapsed since the most recent modification. So multiple subsequent configuration
changes will aggregate to one single update. This reduces the number of service
restarts on the master.
