Trigger an event on spotting certain packets?

[paulobrads]

I'm looking for an app that will trigger a predefined event when a packet with certain credentials is found.

Specifically the triggering of a shell script when an SNMP packet with certain contents is seen would be great.

Any ideas?

I think SNORT will do that for you

Mmm, I've looked at snort and the alarms it sends seem only capable of being logged - no direct execution of anything.

Something I'm missing with that? And/or any other ideas?

Cheers.
