Quite right - I apologize.  I changed the rocommunity and rwcommunity 
strings to verify that the snmpd was looking at the right snmpd.conf 
file, and it is.

Yes.

Yes.  In fact, I can do the following which is 'way cool:
[jeffs@black ~]$ snmpwalk -v 2c -c cvv_test localhost | wc -l
2055
[jeffs@black ~]$          

There is so much interesting stuff, for example, there appears to be a 
dump of the RPM database in there:
 HOST-RESOURCES-MIB::hrSWInstalledName.697  = STRING: "rpm-build-4.1.1-1.8x"
...
HOST-RESOURCES-MIB::hrSWInstalledDate.697 = STRING: 2005-7-6,23:54:20.0,-7:0

so I can do my software audits using SNMP.  Whoo hoo!

I owe you a beer, at least.  Somehow I will get one to you.
