Freeing Ports
 

I have redhat AS 3.0 and I am using an oracle application that use port 1754 or 1748. How do I reconfigure that application to use other TCP ports? How do I freed these ports on my linux box? Here is the solution i found in google.

Solution B:
When the error: (nsi-err1#=12564) appears in the oms.log.0 file, another process other than the Agent maybe listening on port 1748 or 1754.

1. At the target server, use 'netstat -a' to see who is listening on these ports, and reconfigure that application to use other TCP ports.
2. After these ports have been freed, start the Intelligent Agent, and redo the discovery. If you need help freeing the ports, contact your local network administrator to resolve this issue.

What did netstat -a tell you ?
What is listening other than your application on those ports?

Here is the netstat -a output. I added these port 1748 & 1758 to the /etc/services, just now. Any more clues?



[root@MLKK root]# netstat -a |grep 1748
[root@MLKK root]# netstat -a |grep 1758
