Don, I have seen confusing behavior in this area a lot.  First, do you know
that at 6.01, public is used as if it were in the alternates file whether
want it or not, and at 6.02 it is not used unless specified?  I hope you
are at 6.01,
because the explanation would be easier. The next odd thing I have been
seeing is the insertion of bogus communities. But I believe that in almost
case those turned out to be for nodes that had name resolution problems.
up the name resolution in both directions and a couple of demandpolls ( or
rediscovering the node) cleared it up. I know, I know, you couldn't
possibly have
any name resolution problems....;) My routine now includes:

fix any name problems for the node
delete any related xnmsnmpconf entries (name or address)
demandpoll (it will always work, because it tries everything)
check snmp using one of the MIB appls, which only checks xnmsnmpconf

If it works for Monitor..MIB Values..System Info, then it should work for
snmpCollect, I think. The snmpCol.trace will tell you if it also has name

Subject:  [NV-L] community name changes

For the sake of this discussion, let's say that my Global Default community
name is "raleigh".

I have a default communityNames.conf file with no entrys (all comments).

I am NOT using the "-h" netmon flag. (alternate community strings during

Nodes using "raleigh" mysteriously are being added in xnmsnmpconf with a
unique community name of "public".

This really messes up SNMP data collection statistics :(

Has anyone else seen this?
What is happening here?

How do I turn this "feature" OFF ?
