Funny you should mention that...I am trying to write it up from the perspective of people that are familiar with snmp version 1 and I wanted to take an opportunity to educate myself and see that it works (so I am doing things like tcpdump before and after i turn on encryption).

Originally, I thought I could just take...

/usr/samples/snmpdv3/snmpdv3.conf

and be up and running without having to learn the details of the version 3 protocol and implement whatever level of security I want. I suppose if you are an expert in SNMP and have been keeping up the RFC's the sample snmpdv3.conf file makes sense.

I saw a few samples on the web but most seem to still configure the snmpdv3.conf at the lowest level of security (community string).

I think it's time for administrators to re-consider snmp again since it addresses traditional security issues; more importantly, it can save money. The configuration is a small challenge. Administrators--including me--need to invest the time in learning and matching the protocol to the level of security they need.

I will post my results. Thanks for the interest.

NAME
pmc -- performance-monitoring counter interface for command execution SYNOPSIS
pmc -h pmc -C pmc -c event command [options ...] DESCRIPTION
pmc is a means of using a processor's performance-monitoring counter (PMC) facility to measure various aspects of a program's execution. It is meant to be used in a fashion similar to time(1). The arguments are as follows: -h Display a list of performance counter events available on the system. -C Cancel any performance counters that are currently running. -c event Count the event specified by event while running the command. DIAGNOSTICS
PMC support is not compiled into the kernel Performance-monitoring counter support has not been compiled into the kernel. It may be included using the PERFCTRS option. See options(4) for details. PMC counters are not supported by CPU Performance-monitoring counters are not available for the CPU. SEE ALSO
time(1), options(4) HISTORY
The pmc command first appeared in NetBSD 1.6. AUTHORS
The pmc command was written by Frank van der Linden <fvdl@wasabisystems.com>. The kernel support for reading performance counters on the i386 architecture was written by Jason R. Thorpe <thorpej@zembu.com>. BUGS
The pmc command currently only supports performance-monitoring counters on the i386 architecture. BSD
