Port 29120 is used for all communications among the Framework managers and the agents. Port 29120 is also used for communications among the Framework agents.
If firewalls separate your Privileged User Manager machines, this port must be opened to traffic in both directions for Novell Privileged User Manager to work properly.
The port is specified when the agent is registered with the Framework Manager. If you need to specify a different port because an application is already using port 29120, this new port needs to be opened in the firewall for communication.
