Sounds like a network mask issue. If you don't specify one, loadhosts will "guess", which might give you a problem like this. I'm not a big fan of loadhosts for that reason as well as others.

Is there some reason why you cannot just put the IP address at the top of the seed file and issue "netmon -y" to cause him to reread it, or ovstop/ovstart him?

James,
-7.1.3 FP3
-I'm using load hosts command to add to NetView
-oid_to_type has two entries as below:
1.3.6.1.4.1.8072.3.2.10:Linux:Linux UCD-SNMP Agent:S
1.3.6.1.4.1.2021.250.10:Linux:Linux UCD-SNMP Agent:
-Let me explain - When i loadhosts a linux server, after doing a nmdemandpoll, netview reports there are duplicate IP addresses and deletes linux server. After me deleteing those duplicate addresses, i again loadhosts Linux server. this time again netview reports there are duplicate IP addresses which are different from the last time it found . This keeps going on and on when i add and delete. Wonder where and what's wrong?
Larry

Sounds like apples and oranges to me Larry, but with 7.1.3 (Fixpack ??) I wouldn't know. Even FP04 shipped September 30, 2005.

And what do you mean by "manually add the node"? to the seed file? using loadhosts? which?

As for the difference between the net_snmp agent and the ucd_agent, the ucd_agent is precursor to net_snmp.
See http://www.net-snmp.org/about/history.html

What do you have in your /usr/OV/conf/oid_to_type file for the UCD agent you are using? It should be one of these:

1.3.6.1.4.1.2021.250.10:Linux:Linux UCD-SNMP Agent:
1.3.6.1.4.1.8072.3.2.10:Linux:Linux UCD-SNMP Agent:

2021 is the IANA Enterprise number for UC Davis (so it's base for the UCD Agent's initial OID) and 8072 is for the new version, which is net-snmp.

But none of this has anything to do with duplicate IPs so far as I know. I couldn't find any record of netmon getting confused about duplicate IP addresses when discovering a UCD or net-snmp agent, but you can search the archives for yourself.

Good luck.

Hi all,
I'm having an issue to discover the Linux Suse SNMP agent into our Netview (7.1.3). When i manually add the node, it discovers and netmon deletes it right away indicating duplicate IP addresses found and in fact there are no duplicate IP's exist in database.
Has anyone experienced this issue before?
What's the difference bewteen net-snmp and ucd-snmp? Could that be a problem?
Thanks as usual,
Larry
