# snmpd.conf:

#   An example configuration file for configuring the ucd-snmp snmpd agent.

#

###############################################################################

#

# 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"

#       sec.name  source          community

com2sec notConfigUser  default       public

####

# Second, map the security name into a group name:

#       groupName      securityModel securityName

group   notConfigGroup v1           notConfigUser

group   notConfigGroup v2c           notConfigUser

####

# Third, create a view for us to let the group have rights to:

# Make at least  snmpwalk -v 1 localhost -c public system fast again.

#       name           incl/excl     subtree         mask(optional)

view    systemview    included   .1.3.6.1.2.1.1

view    systemview    included   .1.3.6.1.2.1.25.1.1

####

# Finally, grant the group read-only access to the systemview view.

#       group          context sec.model sec.level prefix read   write  notif

access  notConfigGroup ""      any       noauth    exact  systemview none none

# -----------------------------------------------------------------------------

# Here is a commented out example configuration that allows less

# restrictive access.

# 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.

##       sec.name  source          community

#com2sec local     localhost       COMMUNITY

#com2sec mynetwork NETWORK/24      COMMUNITY

##     group.name sec.model  sec.name

#group MyRWGroup  any        local

#group MyROGroup  any        mynetwork

#

#group MyRWGroup  any        otherv3user

#...

##           incl/excl subtree                          mask

#view all    included  .1                               80

## -or just the mib2 tree-

#view mib2   included  .iso.org.dod.internet.mgmt.mib-2 fc

##                context sec.model sec.level prefix read   write  notif

#access MyROGroup ""      any       noauth    0      all    none   none

# Sample configuration to make net-snmpd RFC 1213.

# Unfortunately v1 and v2c don't allow any user based authentification, so

# opening up the default config is not an option from a security point.

#

# WARNING: If you uncomment the following lines you allow write access to your

# snmpd daemon from any source! To avoid this use different names for your

# community or split out the write access to a different community and 

# restrict it to your local network.

# Also remember to comment the syslocation and syscontact parameters later as

# otherwise they are still read only (see FAQ for net-snmp).

# System contact information

syslocation Unknown (edit /etc/snmp/snmpd.conf)

syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)

# Example output of snmpwalk:

#   % snmpwalk -v 1 localhost -c public system

#   system.sysDescr.0 = "SunOS name sun4c"

#   system.sysObjectID.0 = OID: enterprises.ucdavis.ucdSnmpAgent.sunos4

###############################################################################

# Logging

#

# We do not want annoying "Connection from UDP: " messages in syslog.

# If the following option is commented out, snmpd will print each incoming

# connection, which can be useful for debugging.

###############################################################################

# 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.prIndex.2 = 2

# enterprises.ucdavis.procTable.prEntry.prIndex.3 = 3

# enterprises.ucdavis.procTable.prEntry.prNames.1 = "mountd"

# enterprises.ucdavis.procTable.prEntry.prNames.2 = "ntalkd"

# enterprises.ucdavis.procTable.prEntry.prNames.3 = "sendmail"

# enterprises.ucdavis.procTable.prEntry.prMin.1 = 0

# enterprises.ucdavis.procTable.prEntry.prMin.2 = 0

# enterprises.ucdavis.procTable.prEntry.prMin.3 = 1

# enterprises.ucdavis.procTable.prEntry.prMax.1 = 0

# enterprises.ucdavis.procTable.prEntry.prMax.2 = 4

# enterprises.ucdavis.procTable.prEntry.prMax.3 = 10

# enterprises.ucdavis.procTable.prEntry.prCount.1 = 0

# enterprises.ucdavis.procTable.prEntry.prCount.2 = 0

# enterprises.ucdavis.procTable.prEntry.prCount.3 = 1

# enterprises.ucdavis.procTable.prEntry.prErrorFlag.1 = 1

# enterprises.ucdavis.procTable.prEntry.prErrorFlag.2 = 0

# enterprises.ucdavis.procTable.prEntry.prErrorFlag.3 = 0

# enterprises.ucdavis.procTable.prEntry.prErrMessage.1 = "No mountd process running."

# enterprises.ucdavis.procTable.prEntry.prErrMessage.2 = ""

# enterprises.ucdavis.procTable.prEntry.prErrMessage.3 = ""

# enterprises.ucdavis.procTable.prEntry.prErrFix.1 = 0

# 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.

#

###############################################################################

# Executables/scripts

#

#
