My location.log files show no errors in my location.conf file. It is working as it is configured to. here is a thought though. Would this make any sense. Let NV discovery everything I want it to. Create all the selection names, then do a ovobjprint -s to a file (objects.out). After that create a script that would find the ip address associated with the selection name and strip all that out into another file and use that output as the devices to use int he location.conf. The issue we have is that some networks are not being placed in the proper containers even with the location.conf. Some of that has to do with incorrect SNMP strings and unknown strings on some of the devices.
If you have a name in the location.conf and that name does not resolve, then there will be no object on that map with that Selection Name. In that case, there will be a notation in /usr/OV/log/location.log saying that the invalid gateway name is being skipped. If that object is on the map with an IP address for a label and Selection Name, then that is what must appear in location.conf. Cordially, Leslie A.

With regards to Leslie's note. If I am using the Name of the Gateway and not the IP address of it would it not go in and resolve to the correct IP and therefore Selection name. And if it does not and the gateway name is invalid what exactly will happen then?
A common area of confusion with the location.conf file gateway entries: you cannot put just any old address in there. The match will be done on the Selection Name that the router ends up with. Cordially, Leslie A. Clark IBM Global Services - Systems Mgmt & Networking Detroit
This is how I would figure it did the Name resolution. HOwever with Netview running on an AIX box, my UNIX guru's have come to tell me that name resolution is only done via a DNS server from AIX. AIX cannot be configured to use the /etc/hosts file for resolution. We ahve a DNS server that it attaches to. And your answer is what I was looking for Thank you Chris Petrina
NetView himself has no name-to-address resolution mechanism - he uses whatever the host Operating System uses. That is, if all you have is a hosts file with the NetView box in it, everything else will have IP addresses as labels. It is strongly recommended that you have a reliable DNS employed by the NetView system (preferably with the NetView system acting as a caching / secondary DNS server).
