# 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 local localhost public
com2sec network 192.168.2.151/32 public (改成自己的IP)
####
# Second, map the security name into a group name:
# groupName securityModel securityName
group MyROGroup v1 network
group MyROGroup v1 local
group MyROGroup v2c local
group MyROGroup v2c network
view all-mibs included .1 80
####
# 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 .1.3.6.1.2.1.2
view systemview included .1.3.6.1.2.1.25.1.1

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

#access notConfigGroup "" any noauth exact systemview none none

# -----------------------------------------------------------------------------
# Here is a commented out example configuration that allows less

# 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.

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

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

###############################################################################
# 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.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.

# 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).
#
# 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:
# Open up the whole tree for ro, make the RFC 1213 required ones rw.
# name incl/excl subtree mask(optional)

# It is also possible to set the sysContact and sysLocation system

syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)
# Example output of snmpwalk:

# 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 (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.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.prErrorFlag.3 = 0

# enterprises.ucdavis.procTable.prEntry.prErrMessage.2 = ""
# enterprises.ucdavis.procTable.prEntry.prErrMessage.3 = ""

# 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.

# exit 35
#
# Note: this has been specifically commented out to prevent
