How about adding the names and IPs in the hosts file?

My brain is going numb trying to decipher all the things I've dug up via
search.

Two constants tho:  If SNMP is enabled/working, names resolve correctly.
And if reverse DNS is working, names resolve correctly.

So I have a large list of ip's that I know for a fact do not have
reverse DNS set up.  SNMP is also not enabled on them, and as expected
they show up as their ip address in OpenNMS.  Since I'm not Data from
Star trek, this is not good.

But then I noticed today that if I click on one of these nodes, towards
the bottom of the screen where the interface information is, it lists
the ip address, and in parenthesis, it lists some sort of name.  Wether
that's a DNS name, Netbios name, or something else, I don't know - But
it is a readable name instead of IP address.

What is it?  That's question number one.

Two - Is there a way to mass change entries in OpenNMS to use this name
as the node name, at least for all the entries that have somehow
resolved this name?  That would be *fabulous*.

=20

I seem to have an event that states the hostname for this node
changed... Which is nice... But the actual node name is still an ip
address, and I want to get that updated.. Either via a script, or a
config change that does this automatically, or some other method that
doesn't have me touching god knows how many entries manually.

Thanks!
