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

       snmp-ups - Driver for RFC 1628 SNMP UPS equipment

NOTE

       This  man  page	only  documents the hardware-specific features of the snmp-ups driver.	For information about the core driver, see nutups-
       drv(8).

SUPPORTED HARDWARE

       Any UPS that is RFC 1628 (UPS MIB) compliant.

EXPERIMENTAL DRIVER

       This driver has been tagged experimental and is not built by default.

REQUIREMENTS

       This driver needs UCD SNMP, aka Net-SNMP installed to compile successfully.  See http://www.net-snmp.org/ for more information.

       On Red Hat 7.2, these packages are required:

	    ucd-snmp-devel-4.2.3-1, ucd-snmp-4.2.3-1, ucd-snmp-utils-4.2.3-1

       You must install SNMP-UPS-MIB.txt in your MIBs directory - typically /usr/share/snmp/mibs/, but it may vary from system to system.  You can
       generate this from chapter 4 of RFC 1628 (see http://www.faqs.org).

EXTRA ARGUMENTS

       This driver supports the following optional settings in the ups.conf(5):

       community=name
	      Set community name (default = public)

       snmp_version=version
	      Set SNMP version (default = v1, the other allowed value is v2c)

INSTALLATION

       This driver is not built by default.  You can build it by using "configure --with-drivers=snmp-ups" before calling make.

IMPLEMENTATION

       The hostname of the UPS is specified with the "port" value in ups.conf, i.e.:

	    [snmp]
		 driver = snmp-ups
		 port = snmp-ups.example.com
		 community = public
		 snmp_version = v1

SUPPORTED VARIABLES

	    INFO_MFR  UPS Manufacturer
	    INFO_MODEL	   UPS Model
	    INFO_FIRMREV   Firmware/Software Version
	    INFO_STATUS    OFF, OL, OB, BOOST, TRIM
	    INFO_BATTPCT   Battery percentage
	    INFO_RUNTIME   Predicted runtime on battery
	    INFO_BATTVOLT  Battery Voltage
	    INFO_OUTVOLT   Output Voltage

PLANNED SUPPORT

	    INFO_UTILITY   Input Voltage
	    INFO_ACFREQ    AC Frequency
	    INFO_UPSTEM    UPS Temperature
	    INFO_LOADPCT   Load Percentage
	    CMD_?	   Not determined
