| |
| − | ###############################################################################
| |
| − | #
| |
| − | # This file is intended to only be an example. If, however, you want
| |
| − | # to use it, it should be placed in SYSCONFDIR/share/snmp/snmpd.conf.
| |
| − | # When the snmpd agent starts up, this is where it will look for it.
| |
| − | #
| |
| − | # You might be interested in generating your own snmpd.conf file using
| |
| − | # the "snmpconf" program (perl script) instead. It's a nice menu
| |
| − | # based interface to writing well commented configuration files. Try 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
| |
| − | # instead, as it will tailor itself to your configuration.
| |
| − |
| |
| − | # All lines beginning with a '#' are comments and are intended for you
| |
| − | # to read. All other lines are configuration commands for the agent.

| |
| − | # 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 NPG
| |
| − | com2sec mynetwork 10.0.0.0/24 NPG
| |
| − |
| |
| − | ####
| |
| − | # 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
