NAME

       Munin::Node::SNMPConfig - Subroutines providing munin-node-configure's SNMP scanning capabilities.

SYNOPSIS

         my $snmp = Munin::Node::SNMPConfig->new(
               community => 'secret',
               version   => 1,
         );
         $snmp->probe_hosts(\%plugins);

SUBROUTINES

       new(%arguments)
           Constructor.  Valid arguments are:

           hosts
               The list of hosts to scan, in a format understood by Munin::Node::Configure::HostEnumeration.
               Required.

           port
               Port to connect to.  Default is 161.

           version
               The SNMP version to use.  Default is '2c'.

           community
               The community string to use for SNMP version 1 or 2c.  Default is 'public'.

           username
               The SNMPv3 username to use.

           authpassword
               SNMPv3 Authentication password.  Optional when encryption is also enabled, in which case defaults
               to the privacy password ("privpassword").  The password is sent encrypted (one way hash) over the
               network.

           authprotocol
               SNMPv3 Authentication protocol.  One of 'md5' or 'sha' (HMAC-MD5-96, RFC1321 and
               SHA-1/HMAC-SHA-96, NIST FIPS PIB 180, RFC2264).  The default is 'md5'.

           privpassword
               SNMPv3 Privacy password to enable encryption.  An empty ('') password is considered as no
               password and will not enable encryption.

               Privacy requires a v3privprotocol as well as a v3authprotocol and a v3authpassword, but all of
               these are defaulted (to 'des', 'md5', and the v3privpassword value, respectively) and may
               therefore be left unspecified.

           privprotocol
               If the v3privpassword is set this setting controls what kind of encryption is used to achieve
               privacy in the session.  Only the very weak 'des' encryption method is supported officially.  The
               default is 'des'.

               The implementing perl module (Net::SNMP) also supports '3des' (CBC-3DES-EDE aka Triple-DES, NIST
               FIPS 46-3) as specified in IETF draft-reeder-snmpv3-usm-3desede.  Whether or not this works with
               any particular device, we do not know.

       run_probes($plugins)
           Connects to each host in turn, and checks which plugins it supports, based on the OIDs they reported
           during snmpconf.  If all the requirements are fulfilled, it will added to the corresponding plugin's
           suggestions list.

           $plugins should be a Munin::Node::Configure::PluginList object.
