Which protocols/ports does JDisc Discovery uses to connect the user interface client to the server?
Category:
Installation/Update
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:
| Protocol | Port |
|---|---|
| RMI Registry (server side) | 30470 (TCP) |
| RMI Objects (server side) | 30471 (TCP) |
| RMI Objects (client side) | 30212 (TCP) |
