Determine TCP port used by a connection.
We have an application that has our iSeries(AS/400) connect to a remote IP address and port. If we have to end the application and restart it (IPL, error, end/start subsystem) the iSeries keeps the connection open. AFter the application is restarted, the TCP connections show two connections to the...
