RE: TCP/IP Trace -- MIDRANGE-L

I updated the DNS Table. Does TCP/IP need to be recycled to pick up the changes ?

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.

Trace rout shows the correct stuff going to my LPAR and get no response on
the Target Box. I couldn't find LSLOOKUP on my box (V5.4)

Command Library Text
TRACEROUTE QSYS Trace TCP/IP Route
NSLOOKUP QSYS Start NSLOOKUP Query

Use both of these.

Did they change the gateway address at the target location? Check to
insure
that (CFGTCP take option 2) the default gateway is pointing to the address
for that router (Network people will tell you that address).

My 2 iSeries stopped talking to each other on Friday. I can bing from from
my target box to the primary, but not the other way. I can get to the LPAR
on the target box. How do I do a trace from the iSeries ?
Our network people were doing stuff on the routers in the building where
the
target box is located. They are on different sub-nets.
