Which other ports are being used locally on the JDisc Discovery server and client?
The JDisc Discovery user interface makes use of the Java encrypted RMI (Remote Method Invocation).
The port configuration resides in the file <installdir>/configs/Config.xml within the RmiRegistry section:
<RmiRegistry>
<RegistryPort>30470</RegistryPort>
<ServerPort>30471</ServerPort>
<ClientPort>30212</ClientPort>
</RmiRegistry>
IMPORTANT: In builds prior to build 4009, the server port was randomly selected. That made the firewall configuration nearly impossible. We have changed the behaviour in 4009 to use the configured port only!
On the JDisc Discovery server, you need to open the port 30470 and 30471. On the client, you need to open the port 30212.
The following table lists the protocols used by the JDisc Discovery user interface:
The embedded Postgres database server listens by default on Port 25321.
The JDisc Discovery server and the user interface open TCP and UDP connections. Java uses a randomly chosen port between 1023 and 65535. The user interface only uses TCP connections and the JDisc Discovery server also uses UDP (e.g. for the SNMP protocol).Furthermore our JDisc Discovery server communicates locally with the Postgres database server. It uses the same algorithm as described above to open the connection.
