RE: TCP Port question

Ohhh...

That's a horse of a different color; the server on the remote side is not
responding so therefore it needs to be reset. Unfortunately unless it's
documented somewhere about what server it is you might have some interesting
moments trying to find it.

Can you ping the IP address? If so add the -a parm to the ping so it will
report its name. That might help narrow it down.

I'm afraid my wording confused things. The "server" is a unix or Windows
server (not sure of their config) that is listening/waiting for the iSeries
to connection on port 77. When they execute the program on the iSeries for
the client to start talking on port 77, it returns an error saying that it
can't connect to the server on port 77. The client program on the iSeries
is a manual call and not part of the IPL startup.

Then you are looking for a program that is not running and either A) failed
in the startup program, or B) was not there to start with.

I'd look at the job log for the startup program and the history log. Look
at the jobs ending as the IPL started and you might catch the job that
actually was listening on that port.

The port number is 77. Both the client and the server programs are
completely custom.

Gary's correct, check to be sure the host servers started, but I suspect
there is a different server you need started.

What port are you looking for? Is it a well-known port or a custom port?

If it's a custom port you might start by looking to see if all of the WAS,
PHP and/or Apache instances started properly. Check the /www directory for
any apache instances that listen on a custom port.

Should the IWS start?

Are TCP services running on the re-started iSeries ?

Subject: TCP Port question

I have a client that is running a client server system where the iSeries is
a client. When they try to start the job on the iSeries, they are getting a
failure trying to access the specified port. It is my understanding that
the package previously worked and when they did an IPL, it stopped working.
There were supposedly no other configuration changes to the iSeries or the
network. That sounds really strange to me. Unfortunately, at this time I
only have a message that the connection failed. I don't know if it was the
open or the bind or something else that it didn't like. We are adding some
additional logging to the program to try to be a better message than
"connection failed".



In the meantime, I had them do a NETSTAT option 3 and F14 to see the ports
and they said the port in question does not show anything using it. Is
there anything else that anyone can suggest to look at that might show me
what is causing the failure?
