Asterisk SNMP Support
|
|
---------------------
|
|
|
|
Rudimentary support for SNMP access to Asterisk is available. To build
|
|
this, one needs to have Net-SNMP development headers and libraries on
|
|
the build system, including any libraries Net-SNMP depends on.
|
|
|
|
Note that on some (many?) Linux-distributions the dependency list in
|
|
the net-snmp-devel list is not complete, and additional RPMs will need
|
|
to be installed. This is typically seen as attempts to build res_snmp
|
|
as net-snmp-devel is available, but then fails to find certain
|
|
libraries. The packages may include the following:
|
|
* bzip2-devel
|
|
* lm_sensors-devel
|
|
* newt-devel
|
|
|
|
SNMP support comes in two varieties -- as a sub-agent to a running SNMP
|
|
daemon using the AgentX protocol, or as a full standalone agent. If
|
|
you wish to run a full standalone agent, Asterisk must run as root in
|
|
order to bind to port 161.
|
|
|
|
Configuring access when running as a full agent is something that is
|
|
left as an exercise to the reader.
|
|
|
|
To enable access to the Asterisk SNMP subagent from a master SNMP
|
|
daemon, one will need to enable AgentX support, and also make sure that
|
|
Asterisk will be able to access the Unix domain socket. One way of
|
|
doing this is to add the following to /etc/snmp/snmpd.conf:
|
|
|
|
# Enable AgentX support
|
|
master agentx
|
|
|
|
# Set permissions on AgentX socket and containing
|
|
# directory such that process in group 'asterisk'
|
|
# will be able to connect
|
|
agentXPerms 0660 0550 nobody asterisk
|
|
|
|
This assumes that you run Asterisk under group 'asterisk' (and does
|
|
not care what user you run as).
