Re: CFGTCP Host Tables where used

["Larry \"DrFranken\" Bolhuis" <midrange@xxxxxxxxxxxx>]

'The Perfect' hosts file contains ONLY the name of your server such as:


172.x.y.x	common1.frankeni.com
		common1

and the loopback addresses. Nothing more, nothing less.

Any other entries in there are referred to as 'land mines.' You will 
forget they are in there. They will be changed in DNS at some point. 
They will stop working. You will be frustrated. The network team will 
complain such as 'AS/400 is bad.'

IBM does recommend the above entry for your host only so that everything 
starts up correctly at IPL. In some cases things are starting before 
access to DNS is all square and this can cause issues. I have used DNS 
instead of the above entry however and it usually works great.

On a side note, your list of routes should be the same length- 1. Same 
reason. As Tigger (That's Tee Aye Double-Guh ER) from the 100 acre wood 
likes to say: "Let your routers do the routing, it's what Routers do BEST"
