# You might be interested in generating your own snmpd.conf file using

it!

# Note: This file is automatically generated from EXAMPLE.conf.def.
# Do NOT read the EXAMPLE.conf.def file! Instead, after you have run
# configure & make, and then make sure you read the EXAMPLE.conf file

# Access Control
###############################################################################
# YOU SHOULD CHANGE THE "COMMUNITY" TOKEN BELOW TO A NEW KEYWORD ONLY
# KNOWN AT YOUR SITE. YOU *MUST* CHANGE THE NETWORK TOKEN BELOW TO
# SOMETHING REFLECTING YOUR LOCAL NETWORK ADDRESS SPACE.
# 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 as well.
#
# The following lines change the access permissions of the agent so
# that the COMMUNITY string provides read-only access to your entire
# NETWORK (EG: 10.10.10.0/24), and read/write access to only the
# localhost (127.0.0.1, not its real ipaddress).
#
# For more information, read the FAQ as well as the snmpd.conf(5)
# manual page.
####
# First, map the community name (COMMUNITY) into a security name
# (local and mynetwork, depending on where the request is coming
# from):
# sec.name source community
com2sec local localhost public
com2sec mynetwork 136.170.0.0/16 public
####
# Second, map the security names into group names:
# sec.model sec.name
group MyRWGroup v1 local
group MyRWGroup v2c local
group MyRWGroup usm local
group MyROGroup v1 mynetwork
group MyROGroup v2c mynetwork
group MyROGroup usm mynetwork
####
# Third, create a view for us to let the groups have rights to:
# incl/excl subtree mask
view all included .1 80
####
# Finally, grant the 2 groups access to the 1 view with different
# write permissions:
# context sec.model sec.level match read write
notif
access MyROGroup "" any noauth exact all all none
access MyRWGroup "" any noauth exact all all none
#
-----------------------------------------------------------------------------
###############################################################################
# System contact information
#
# It is also possible to set the sysContact and sysLocation system
# variables through the snmpd.conf file. **PLEASE NOTE** that setting
# the value of these objects here makes these objects READ-ONLY
# (regardless of any access control settings). Any attempt to set the
# value of an object whose value is given here will fail with an error
# status of notWritable.
syslocation Right here, right now.
syscontact Me <***@somewhere.org>
# Example output of snmpwalk:
# % snmpwalk -v 1 -c public localhost system
# system.sysDescr.0 = "SunOS name sun4c"
# system.sysObjectID.0 = OID:
enterprises.ucdavis.ucdSnmpAgent.sunos4

# 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:
#
# 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 prTable would look something like this:
#
# % snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2021.2
# enterprises.ucdavis.procTable.prEntry.prIndex.1 = 1
# enterprises.ucdavis.procTable.prEntry.prIndex.2 = 2
# enterprises.ucdavis.procTable.prEntry.prIndex.3 = 3
# enterprises.ucdavis.procTable.prEntry.prNames.1 = "mountd"

# 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.

Post by GeekSrikI'm using a very simple trap daemon and snmpd both configured in a
simple manner (authcommunity, etc as per all examples on the net)
I also set a trap handle something like this for the test trap mib
(UCD-TRAP-TEST-MIB.txt)
Authcommunity log, execute, net public
Traphandle UCD-TRAP-TEST-MIB::demoTrap ls
All I want to do is do an 'ls' on the current directory upon receiving
trap.
I do get the trap as well when I raise it using following command.
snmptrap -v 1 -c public 136.170.195.178 UCD-TRAP-TEST-MIB::demoTrap
