# This file is intended to only be as a starting point.  Many more
 
# configuration directives exist than are mentioned in this file.  For
 
# full details, see the snmpd.conf(5) manual page.
 
#
 
# All lines beginning with a '#' are comments and are intended for you
 
# to read.  All other lines are configuration commands for the agent.

# Access Control
 
###############################################################################
 
 
# As shipped, the snmpd demon will only respond to queries on the
 
# system mib group until this file is replaced or modified for
 
# security purposes.  Examples are shown below about how to increase the
 
# level of access.
 
 
# By far, the most common question I get about the agent is "why won't
 
# it work?", when really it should be "how do I configure the agent to
 
# allow me to access it?"
 
#
 
# By default, the agent responds to the "public" community for read
 
# only access, if run out of the box without any configuration file in
 
# place.  The following examples show you other ways of configuring
 
# the agent so that you can change the community names, and give
 
# yourself write access to the mib tree as well.
 
#
 
# For more information, read the FAQ as well as the snmpd.conf(5)
 
# manual page.

# First, map the community name "public" into a "security name"

group  notConfigGroup v2c          notConfigUser

# Process checks.
 
#
 
#  The following are examples of how to use the agent to check for
 
#  processes running on the host.  The syntax looks something like:
 
#
 
#  proc NAME [MAX=0] [MIN=0]
 
#
 
#  NAME:  the name of the process to check for.  It must match
 
#        exactly (ie, http will not find httpd processes).
 
#  MAX:  the maximum number allowed to be running.  Defaults to 0.
 
#  MIN:  the minimum number to be running.  Defaults to 0.
 
 
#
 
#  Examples (commented out by default):
 
#
 
 
#  Make sure mountd is running
 
#proc mountd
 
 
#  Make sure there are no more than 4 ntalkds running, but 0 is ok too.
 
#proc ntalkd 4
 
 
#  Make sure at least one sendmail, but less than or equal to 10 are running.
 
#proc sendmail 10 1
 
 
#  A snmpwalk of the process mib tree would look something like this:
 
#
 
# % snmpwalk -v 1 localhost -c public .1.3.6.1.4.1.2021.2
 
# enterprises.ucdavis.procTable.prEntry.prIndex.1 = 1

# enterprises.ucdavis.procTable.prEntry.prErrFix.2 = 0
 
# enterprises.ucdavis.procTable.prEntry.prErrFix.3 = 0
 
#
 
#  Note that the errorFlag for mountd is set to 1 because one is not
 
#  running (in this case an rpc.mountd is, but thats not good enough),
 
#  and the ErrMessage tells you what's wrong.  The configuration
 
#  imposed in the snmpd.conf file is also shown. 
 
#
 
#  Special Case:  When the min and max numbers are both 0, it assumes
 
#  you want a max of infinity and a min of 1.

General Information

Taro is a data/computation server.

Hostnames: taro.unh.edu, taro.farm.physics.unh.edu

Network Configuration

Currently has ethernet cable to switch for local (farm) connection, and an ethernet cable to the wall for unh connection.
