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

11 community => 'secret',
12 version => 1,
13 );
14 $snmp->probe_hosts(\%plugins);
15
17 new(%arguments)
18 Constructor. Valid arguments are:
19
20 hosts
21 The list of hosts to scan, in a format understood by
22 Munin::Node::Configure::HostEnumeration. Required.
23
24 port
25 Port to connect to. Default is 161.
26
27 version
28 The SNMP version to use. Default is '2c'.
29
30 community
31 The community string to use for SNMP version 1 or 2c. Default
32 is 'public'.
33
34 domain
35 The Transport Domain to use for exchanging SNMP messages. The
36 default is UDP/IPv4. Possible values: 'udp', 'udp4',
37 'udp/ipv4'; 'udp6', 'udp/ipv6'; 'tcp', 'tcp4', 'tcp/ipv4';
38 'tcp6', 'tcp/ipv6'.
39
40 username
41 The SNMPv3 username to use.
42
43 authpassword
44 SNMPv3 Authentication password. Optional when encryption is
45 also enabled, in which case defaults to the privacy password
46 ("privpassword"). The password is sent encrypted (one way
47 hash) over the network.
48
49 authprotocol
50 SNMPv3 Authentication protocol. One of 'md5' or 'sha'
51 (HMAC-MD5-96, RFC1321 and SHA-1/HMAC-SHA-96, NIST FIPS PIB 180,
52 RFC2264). The default is 'md5'.
53
54 privpassword
55 SNMPv3 Privacy password to enable encryption. An empty ('')
56 password is considered as no password and will not enable
57 encryption.
58
59 Privacy requires a v3privprotocol as well as a v3authprotocol
60 and a v3authpassword, but all of these are defaulted (to 'des',
61 'md5', and the v3privpassword value, respectively) and may
62 therefore be left unspecified.
63
64 privprotocol
65 If the v3privpassword is set this setting controls what kind of
66 encryption is used to achieve privacy in the session. Only the
67 very weak 'des' encryption method is supported officially. The
68 default is 'des'.
69
70 The implementing perl module (Net::SNMP) also supports '3des'
71 (CBC-3DES-EDE aka Triple-DES, NIST FIPS 46-3) as specified in
72 IETF draft-reeder-snmpv3-usm-3desede. Whether or not this
73 works with any particular device, we do not know.
74
75 run_probes($plugins)
76 Connects to each host in turn, and checks which plugins it
77 supports, based on the OIDs they reported during snmpconf. If all
78 the requirements are fulfilled, it will added to the corresponding
79 plugin's suggestions list.
80
81 $plugins should be a Munin::Node::Configure::PluginList object.
