SNMP traps not caught in Windows XP

I have an SNMP client, sending my PC SNMP traps with destination port 162. I run a sniffer (Wireshark) from my PC, and see that the traps are indeed received. The SNMP.exe and SNMPTRAP.exe system processes are up and running (I've even restarted them),and SNMPTRAP.开发者_运维知识库exe is listening to port 162. I have no activated firewall (whether Windows or 3rd party).

The problem: On my PC I have three different applications, all registered to SNMPTRAP.exe. These are all off-the-shelf sw, not something I wrote. MG-SOFT Trap Ringer is, f.e., one of

them. NONE OF THEM CATCHES ANY OF THE TRAPS, and I have no idea where exactly the failure is.

Do you have any idea what may be causing this? Or how, perhaps, I can debug the SNMPTRAP.exe process?

Thanks!

You may disable Microsoft Trap Service in Services panel. Then MG-SOFT TRAP Ringer will work.

The reason is simply that when Microsoft's SnmpTrap.exe monitors port 162, it prevents other applications, such as MG-SOFT's one from monitoring that port.

How you can eliminate and corner the problem is, try below stuff.

1. How are sure its not catching traps ( since u see them in wireshark). I mean, should they be displayed on some GUI Screen, if yes are the fields empty? or logged into some file, if yes are you sure you are checking the correct file, have you configured either through conf files or command line options which file the traps need to be logged in?

2. If step 1 does not work, try installing or configuring the whole setup on different pc /laptop and see if it works?

3. If step 2 does not work, try a different trap daemon program ( SNMPTRAP.EXE), plenty of open source programs exist, if you could capture with different daemon program, then some issue with SNMPTRAP.EXE you are using.

I'm sure one of these steps should work for you, if not get back :)
