The STRRSESVR command fails when I try to associate an interactive job

About this task

The STRRSESVR command needs to create a TCP/IP socket connection from the IBM® i server back to the Remote System Explorer, to associate the 5250 emulator with a Remote System Explorer connection. The most common error you see when the STRRSESVR command fails is the following RSE2001 message: Error connecting to Remote System Explorer.
Below are some possible problems and their solutions:
  • A firewall, which could have been installed on your local workstation, on the network, or on the IBM i server, is blocking the socket connection. To solve this problem, you need to configure a rule for the firewall to allow for a connection from your workstation to port 4300 on the IBM i server.
  • The STRRSESVR command can not correctly determine the IP address of your workstation. Check the second level help of the RSE2001 error message by pressing F1 on the message; it should list the IP address that the server is trying to use. If this is not the correct IP address of your workstation, then prompt the STRRSESVR command, press F10 for additional parameters, and specify the workstation's IP address in the Remote Location Name field.
  • The port specified as a parameter (default value of 4300) on the STRRSESVR command does not match the port monitored by the RSE communications daemon. If so, you can set the port by going to Preferences > Remote Systems > > Communications.
    Note: The daemon must be started.
