Common Agent Port Numbers
By default, the Common Agent uses port number 6051 for both TCP and UDP. To change the default port, you must modify the ABcmagt section of the agent.cfg file with the new port numbers, and then restart the Common Agent by issuing the caagent stop command, followed by the caagent start command. Do not use the caagent update command after modifying port numbers.
Note: Under normal conditions, do not use this method to start or stop the Common Agent. Instead, you should run the Start and Stop scripts of the individual UNIX, Linux, and Mac OS X client agents installed on the system.
The following sample shows the configuration file before and after the script changes are made.
Before the change:
[36] #[ABcmagt] #NAME ABcmagt #HOME /opt/Arcserve/ABcmagt #TCP_PORT 6051 #UDP_PORT 6051
After the change:
[36] #[ABcmagt] NAME ABcmagt HOME /opt/Arcserve/ABcmagt TCP_PORT 9051 UDP_PORT 9051
The port changes take effect only after you restart the Common Agent. If you configure the Common Agent to run on a port other than the default port, you should also configure the Arcserve Backup server to access this Common Agent. You can do this by making an entry for the client agent in the port.cfg file. This file is in the config subdirectory under the home directory— $AB_HOME/config/port.cfg—on the backup server.
By default, the Common Agent uses another UDP port, 0xA234 (41524), to receive Arcserve Backup requests for the Auto Discovery of UNIX, Linux, and Mac OS X client agents. This port is not configurable.
