"Could not start trap listener on port 162...Permission denied" reported by V5.8.5 GenericSNMPTrapAgent running from Linux FglAM
Beschreibung

Devices were discovered but the GenericSNMPTrapAgent is not receiving traps.
The SNMPTrapAgent is running from a Linux FglAM (Foglight Agent Manager).
The GenericSNMPTrapAgent log reports the following ERROR:
2016-02-25 21:52:40.700 ECHO <fb8be857-fbcf-4747-973d-295a8570e581/GenericSNMPTrapAgent/5.8.5/GenericSNMPTrapAgent/GenericSNMPTrapAgent-agent> ERROR [FglAM:RestoreAgent[16]-4] com.quest.monitoring.snmptrap.agent.GenericSNMPTrapAgent - Could not start trap listener on port 162
com.quest.monitoring.snmp.trap.SnmpTrapListenerCannotStartException: Unable to create trap listener. There may be another trap listener (snmp simulator?) already running. No traps will be received.
...
Caused by: java.net.BindException: Permission denied
Ursache

The FglAM is running as the "foglight" user on a Linux host. Non-root users cannot bind to ports below 1024 on Linux hosts by default. Since the FglAM is running as a non-root user it cannot bind to the port 162.
Lösung

Modify the snmpTrapPort property of the GenericSNMPTrapAgent to use a port value above 1024 if the FglAM will be run as a non-root user.
Run the FglAM as the root user if using port 162 is desired.
