Changing the TCP port for the Micetro Update Agent - Micetro - 26.1.0

The Micetro Update Agent is listening by default on port 4603/TCP. Although the port 4603/TCP is reserved for the Update Agent in the IANA database, there might be a different software already running on that port.

The TCP port for the updater service can be changed. It must be changed on the mmupdate service and also on Micetro Central (mmcentral). All remote servers must listen on the same TCP port for update messages from Micetro Central. It is not possible to run the Update Agent on different ports for different servers.

1. Stop both services, the Micetro Central service and the remote Update Agent.
2. On the machine running the Update Agent, append the following line to the Update Agent's preferences.cfg file (create the file if it does not exist):

   <Arguments value="-p 12345" />

   Where 12345 is the TCP port number the Update Agent should use.

3. Start the Update Agent and check that the process in listening on the new port (using netstat-na or lsof -i).
4. On the machine running Micetro Central, append the following line to the Micetro Central preferences.cfg file (create the file if it does not exist):

   <UpdateAgentPortNumber value="12345" />

   Where 12345 is the TCP port number the Update Agent is using on the remote system(s).

5. Start Micetro Central.
