I'm trying to integrate SNMP Traps into my OpenSUSE 11-based Nagios installation. I've been looking around a little bit and haven't been able to find a daemon that will run on my server and receive SNMP traps from the various network devices (UPS's and Switches). I'd like to eventually have full integration to the point where if an error gets sent to my Nagios server, it will notify me via email. However, I don't even have the service to receive the traps yet, so I was wondering if anyone here could help me find something that would work out.

I've installed Net-SNMP, but it only really seems to enable SNMP requests from the server to the devices (for polling CPU usage and such, which works BTW), but the service snmptrapd seems to be missing.
