I’ve been struggling to get Rational Developer working while remote during the Rona. While I’m working locked in my cellar, candles flickering, dogs growling and rats a scurrying, my laptop is connected with VPN and my guess is that VPN is blocking ports that RD/i needs for the connection.
So, if you are remote and see this glorious error message:
The chances are you need to open some ports in your VPN or firewall configuration.
The mandatory ports for Rdi are: 8470, 8475, 8476, 446, 449
We also have some optional ports for Debug, IFS etc: 8473, 8472, 4300, 3825
|Product function||Required TCP/IP ports on IBM i|
|Remote System Explorer functions: including filtering, editing, compiling, and running||8470: IBM i central server8475: IBM i remote command server8476: IBM i signon server446: IBM i DRDA® (record access) server449: IBM i server mapper server|
|Integrated File System (IFS) access||8473: IBM i file server|
|Interactive job support (via the STRRSESVR command)||8472: IBM i data queue server|
|Local port for interactive job support (via the STRRSESVR command)||4300: Remote System Explorer communications daemon.This is a local workstation port that the STRRSESVR command uses to monitor “call backs” from the IBM i server to your local workstation.|
|Local port for integrated i Debugger||3825: Debugger serverThis is the local port the debugger uses to communicate with the IBM i.|
You need ports 8470, 8475, 8476, 446, and 449 to remain open for proper functioning of the product. However, you only need to keep the IFS and Interactive job support ports open if you require those functions.To change the local Remote System Explorer port that your workstation uses to connect to the IBM i server:
To change the port that the debugger server listens on, use the IBM i WRKSRVTBLE command and add or change the entry QDBGSVR2. If this entry is not found in the table, the debugger server listens on the default port 3825
