Simon,

Thanks for the additional tip with regards to using WRKSRVTBLE in addition to
NETSTAT,  it would appear that neither tool provides a complete picture
though.....

My understanding is that you should start looking for port assignments above
1024 any recommendations?

You need to examine the contents of the services file.  Run the command CFGTCP

and take option 21 and then option 1 (or just run the WRKSRVTBLE command).
The
resulting list is the list of assigned ports.  Not all of them will be active
on
your system but you should not use any of the assigned ports unless you have a

very good reason for so doing.

Pick a port number that is not in the list and use that for your application.

If your application is written properly it should be telling you to add an
entry
in the services table and the application will use the port associated with
the
entry.

It is not sufficient to use NETSTAT to determine available ports because that
lists only the active ports not the assigned ones.

Regards,
Simon Coulter.
