Re: Can't send SNMPv3 Traps from C Program

David,

Thank you for confirming that I have been using the correct library
function calls, your help is very much appreciated.  Now that I know I am
using the correct functions I have managed to work out how to turn on some
of the debugging and located an area of code that is causing problems.

An error is being logged > ‘snmpd: send_trap: USM unknown security name
(no such user exists)’, this is raised because net-snmp calls a function
called usm_get_user and there are no users listed in the puserList 
variable used in snmpusm.c

Where should users be configured, I thought that when sending traps, 
users only need to be configured on the trap sink so why does the net-snmp
library try to look up the user in this list?

Darryl
