RE: Problems using snmptrap
From: Bowers Mike-cmb004 [mailto:michael.bow...@motorola.com] Sent: Wednesday, February 03, 2010 5:47 AM Nothing at all. When I execute the command it immediately returns the prompt. That's why I'm beginning to suspect the snmptrap executable is either messed up, or I'm missing some sort of configuration somewhere. Other commands in the util suite will show some sort of usage info when -h is given as an option. However, if I try this with snmptrap I still get absulutely nothing - it immediately returns to the command prompt. Does your fiewall have port 162 open? Have you tried sending to 127.0.0.1 (Same machine for send and receive, correct?)?

But surely this would only affect whether the trap was *received* by snmptrapd? Mike(B) has said that turning on debugging on the client side indicates that the notification was never actually sent in the first place. I'm inclined to agree that this points the finger at a problem with the snmptrap command itself.

RE: Problems using snmptrap
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.

I'm using verision 5.5 on Windows. I'm able to run the snmptrapd utility and am able to send traps to it successfully from a mib browser. The MIB I'm using for the trap is the one that is given in the tutorial at the netsnmp site. However, when I try to send traps from the command line using snmptrap I see no errors, but the snmptrapd console shows nothing either. All the other utils seem to work except snmptrap. Any pointers? Perhaps you could give us some details about what exactly you've tried. I try to send traps from the command line is a bit vague. Please post:: - the trap-related settings from snmpd.conf - the snmptrap command(s) that you have been trying - the snmptrapd.conf settings Maybe then we might be able to suggest what could be wrong.
