Re: Management Central Server Won't Start

Jerry,

Your system has an identity crisis. Until it knows who it is *MGTC and other servers too will not run.

In your case the simplest fix is:

In CFGTCP option 12 (CHGTCPDMN) give the system a name on the first line. As you show, the suggested name would be DTO because that's already in the hosts table for your IP address. Also in option 12, since you don't have any DNS servers listed, change the search priority to *LOCAL.

Now since you suggest DTO.LOCAL for your domain name you'll also want to go into option 10 and add DTO.DTO.LOCAL to the IP 123.456.78.241.

Now when you PING DTO.DTO.LOCAL you should get the 123.456.78.241 address (Or you would if it was a legal address. :-} ) In any case it must match the IP address in NETSTAT *IFC for your system. Once that works you'll be able to start *MGTC as it will know itself.

that the *MGTC server wasn't running (duh) so I started it. No dice.



A judicous (I hope) search of the archives and other sources pointed me to
the fact that TCP probably was not configured properly.



My previous employer let me look at and print its TCP configuration so that
I could do a comparison.



Before I go further, allow me to explain that the DNS at the previous
employer was on a Windows server (2003). The DNS here is at Comcast.Net. I
have looked at the "cabling," and I just get confused. Those of you that
know me (you know who you are, don't lie) know that I'm no network or
sysadmin guy.



Below is our current configuration (bear in mind that 123.456.78.241 is an
obfuscated IP address for obvious reasons).

Even if I am on the right track so far, I have no idea what to change the
Domain name server's Internet Address.



I do know that, if I run PING MIDRANGE.COM from the System i, I get "Unknown
host" as the reply. Though doing so in the Windows CMD Prompt works fine.



I would rather not go making changes willy-nilly to see what, if anything,
works. Saw a guy do that years ago; we had to reload the system from a
backup tape.



Of course, I could leave well enough alone. Most of the functions that I
use regularly in iNav work fine, though this change might also allow me to
use Netserver to map an IFS folder to a network drive in Windows Explorer.
