Re: Choosing a domain when configuring TCP/IP on As/400

[Jim Langston <jimlangston@xxxxxxxxxxxxxxxx>]

CFGTCP
option 10 (Host Table Entries)
add ARCNET.COM as 192.68.0.170

that should fix your problem.

The AS/400 should check the host table entries before it tries DNS
name resolution (same as the C:\WINDOWS\HOSTS. file).

I have my AS/400 set up in CHGTCPDMN as host name AS400 (original, eh?) and
domain ARCTOOLS.COM.  IP address is internal, 192.68.0.170 (guess what model
I have...).
 
ARCTOOLS.COM is hosted out there on the internet someplace, not in-house.
Even so, this has worked OK so far.
 
Now, I'm trying to get Websphere working.  It seems that Websphere is
unhappy because it's trying to resolve ARCTOOLS.COM for some reason.  DNS is
returning 216.something (the ISP/web site).  For some reason, Websphere
wants to talk to domain ARCTOOLS.COM.  It can't because I have the AS400
behind a PC firewall.  So, after half an hour or so, Websphere gives up and
dies.
 
I'm looking for advice.  What DOMAIN _should_ I use?  Does anyone know the
impact of changing a domain?  If Websphere is looking to talk to
ARCTOOLS.COM, what is it looking for?
 
I am currently testing setting up an entry in the host table to override the
DNS reply and point ARCTOOLS.COM to another server inside.  Maybe that will
fool it into working properly.
 
Any thoughts?
