Sorry for the direct email - will keep that in mind! In response to your questions:
1) Yes - the trap receiver is listening on the specified addressed. I also tried running the snmptrapd command without that address specified with the same results. 2) For "host" in the snmptrap command I've tried 10.2.135.137 as well as 10.2.135.137:162 - same results - nothing happens. 3) With -d on the trap receiver I see packet dumps only when sending from the mib browser. If I send using snmptrap I see nothing. I'm suspecting that there's something wrong with the snmptrap executable at this point. If I try running snmptrap -h I still get absolutely nothing on the console.

Which indicates that the receiver is working fine.

The one thing that springs to mind is to make sure that the destination specified on the snmptrap command line matches the address that the receiver is listening on. If that doesn't fix it, try running both receiver and sender with the flag '-d', to dump the raw packets. What do you see on either side?
