RE: TCP/IP Trace

Rob,

I would disagree with your statement, that when doing a CFGTCP
option 10, that you should NOT see SYSTEM B when on SYSTEM A. I say that it
is optional. Most of my customers will put an entry for their other iSeries
systems in their iSeries Host Table (CFGTCP option 10), and set it to
resolve first locally. I would also think that most people who don't have
an internal DNS, will also put System names and addresses into the iSeries
Host Table.

My point is that not everyone has the same type of infrastructure as
you, so both can be correct depending on the needs, requirements, and
resources of the company.

Make sure you didn't do anything silly like put the remote sites into your
host tables. Rely on DNS instead.
Details:
Suppose you have SYSTEMA and SYSTEMB. If you do
CFGTCP
10. Work with TCP/IP host table entries
you should not see SYSTEMB when you are doing that on SYSTEMA.
you should not see SYSTEMA when you are doing that on SYSTEMB.

You should be using DNS instead. See:
CFGTCP
12. Change TCP/IP domain information
F10=Additional parameters
pgDn
Record any address(es) stored in
Domain name server:
Internet address
and ask your network people if they are still valid.

Our network consultant justifies his existence by occasionally changing
the IP addresses of our DNS, changing the subnets our i's reside in and
other fun stuff. At least he no longer changes all three DNS at once.
Yes, when he changes one of our i's we have to change the interface for
each machine on just that machine.

You should have more than one DNS.
