Actually, try using the host command:

host <hostname>

This should use the standard OS lookup and can easily
be tested.

Chris,

   That's because the nslookup command does NOT use the operating
system gethostbyname() APIs call in the way that NetView does when it
does a lookup.

nslookup is a compiled binary program specifically for interfacing to
DNS.

A better test would be to attempt to ping the device. Ping and netview both use the gethostbyname() API as provided by the operating system. Therefore ping should behave exactly as you have

configured the OS using netsvc.conf.

I verified on the AIX box that netsvc.conf is setup as

hosts-local,bind. I then tried doing a NSLookup by device name from the box and it returned

only that it could not find it in the DNS server.  I did verify that it

was in the /etc/hosts file though. That is where I guess I am asking about Netview. Does it just execute a nslookup when it receives a device name?

Thanks

Great, but your DNS guys are mistaken if they think you cannot override

DNS locally on AIX with an /etc/hosts file.
To do it, you need another file called /etc/netsvc.conf.   In there you

specify the order in which you would like name resolution to proceed.
For example,
        hosts = local, bind
says to use your local /etc/hosts first, and if no match is found, then

go to DNS. Lot's of NetView users employ this.

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).

Cheers,

how does netview look attempt to determine the name of a device.

i.e. in my location.conf file I am using names in place of IP addresses for my gateways. How does Netview resolve the name on a

AIX

box?
