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.
