LinuxSecurity.com: The net-snmp daemon implements the "simple network management protocol". The version 3 of SNMP as implemented in net-snmp uses the length of the HMAC in a packet to verify against a local HMAC for authentication. An attacker can therefore send a SNMPv3 packet with a one byte HMAC and guess the correct first byte of the local HMAC with 256 packets (max).

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
