4 Rudimentary support for SNMP access to Asterisk is available. To build
5 this, one needs to have Net-SNMP development headers and libraries on
6 the build system, including any libraries Net-SNMP depends on.
8 Note that on some (many?) Linux-distributions the dependency list in
9 the net-snmp-devel list is not complete, and additional RPMs will need
10 to be installed. This is typically seen as attempts to build res_snmp
11 as net-snmp-devel is available, but then fails to find certain
12 libraries. The packages may include the following:
17 SNMP support comes in two varieties -- as a sub-agent to a running SNMP
18 daemon using the AgentX protocol, or as a full standalone agent. If
19 you wish to run a full standalone agent, Asterisk must run as root in
20 order to bind to port 161.
22 Configuring access when running as a full agent is something that is
23 left as an exercise to the reader.
25 To enable access to the Asterisk SNMP subagent from a master SNMP
26 daemon, one will need to enable AgentX support, and also make sure that
27 Asterisk will be able to access the Unix domain socket. One way of
28 doing this is to add the following to /etc/snmp/snmpd.conf:
30 # Enable AgentX support
33 # Set permissions on AgentX socket and containing
34 # directory such that process in group 'asterisk'
35 # will be able to connect
36 agentXPerms 0660 0550 nobody asterisk
38 This assumes that you run Asterisk under group 'asterisk' (and does
39 not care what user you run as).
