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).
