Configuring NetSnmp to send trap to NMS

Sirius Black — Fri, 03 Feb 2006 04:30:33 GMT

Hi all,
I'm trying to send trap from my snmp agent automatically to monitor some things on my Linux server...
The problem is that I configure the snmpd.conf file then I start the agent:
/usr/sbin/snmpd -c /root/snmpd.conf.
On my NMS I see the start of the agent.
I put in my snmpd.conf a monitor for the size of a file...
But when I reach the size no one traps is sent to the NMS!!!

Any suggestion ?
Thanks Fabrizio

this is my snmpd.conf file:

Hi

I suggest you use ethereal to monitor snmp packet this is ususally what I do.

I think the problem is that the traps were not sent at all by some reason. Ethereal will be able to clearify this.

thanks
