Setting up some new AlmaLinux 9 boxes running Asterisk 16.29 and NET-SNMP 5.9. I’m unable to query snmpd for Asterisk stats. This same config works without issue on some (much) older servers running Scientific Linux 6.10, Asterisk 11.9, and NET-SNMP 5.5.
Has anyone had any success using SNMP in an EL9 environment? I’m just hoping I don’t have to get out gdb to get to the bottom of this…
AgentX support is enabled in snmpd.conf:
master agentx
agentXSocket tcp:localhost:705
I can see it listening on TCP 705:
$ ss -plant
State Recv-Q Send-Q Local Address:Port Peer Address:Port Process
LISTEN 0 5 127.0.0.1:705 0.0.0.0:* users:(("snmpd",pid=85464,fd=9))
Module res_snmp.so is successfully loaded and the agent activated:
[2022-11-22 12:12:42] VERBOSE[84867] loader.c: Loading res_snmp.so.
[2022-11-22 12:12:42] VERBOSE[84867] res_snmp.c: Loading [Sub]Agent Module
[2022-11-22 12:12:42] VERBOSE[84867] loader.c: res_snmp.so => (SNMP [Sub]Agent for Asterisk)
[2022-11-22 12:12:42] VERBOSE[84913] snmp/agent.c: Starting SubAgent
But I see no subagents registered when I try walking the nsModuleTable MIB, and there are no active connections to TCP 705.
