############################################################################### # # 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 all included .1 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 all 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.

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) #view roview included .1 #view rwview included system.sysContact #view rwview included system.sysName #view rwview included system.sysLocation #view rwview included interfaces.ifTable.ifEntry.ifAdminStatus #view rwview included at.atTable.atEntry.atPhysAddress #view rwview included at.atTable.atEntry.atNetAddress #view rwview included ip.ipForwarding #view rwview included ip.ipDefaultTTL #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteDest #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteIfIndex #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteMetric1 #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteMetric2 #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteMetric3 #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteMetric4 #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteType #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteAge #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteMask #view rwview included ip.ipRouteTable.ipRouteEntry.ipRouteMetric5 #view rwview included ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaIfIndex #view rwview included ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaPhysAddress #view rwview included ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaNetAddress #view rwview included ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaType #view rwview included tcp.tcpConnTable.tcpConnEntry.tcpConnState #view rwview included egp.egpNeighTable.egpNeighEntry.egpNeighEventTrigger #view rwview included snmp.snmpEnableAuthenTraps # 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 roview rwview none ############################################################################### # System contact information # # It is also possible to set the sysContact and sysLocation system # variables through the snmpd.conf file: 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 # system.sysUpTime.0 = Timeticks: (595637548) 68 days, 22:32:55 # system.sysContact.0 = "Me <me@somewhere.org>" # system.sysName.0 = "name" # system.sysLocation.0 = "Right here, right now." # system.sysServices.0 = 72 ############################################################################### # 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. dontLogTCPWrappersConnects yes # ----------------------------------------------------------------------------- ############################################################################### # Process checks. # # The following are examples of how to use the agent to check for # processes running on the host.
