Configure NET-SNMP (Windows) for Splunk to send traps to NMS

mship — Tue, 05 Mar 2013 15:14:54 GMT

I am having a heck of a time understanding NET-SNMP configuration and am hoping that has successful done this for windows can assist me. Please do not post links to NET-SNMP tutorials etc as I have been through ALL of them and I am still having issues.

Really all I need to figure out is how change the port on the NET-SNMP and NET-SNMPtrap service to use ports 1161 and 1162. I have tried snmpconf -i and did not have much luck.

I do not have the answer but a similar problem.

We are trying to get alerts from Splunk to generate snmp traps which we want to set to another vendor's snmp server. We have tried both batch and perl scripts at
link text

But no luck. We have been able to get splunk alerts to run echo.bat but not script that send snmp traps. Very frustrating.

Ok, I found a useful debugging link -> http://wiki.splunk.com/Community:TroubleshootingAlertScripts

Which helped me create a batch (Windows) script that really worked.

Here it is. Maybe it will help the next person.
Change content to meet your specific needs.
Uncomment the echo lines for debug.

@echo off

:echo ---------------------------------------- >> "n:\temp\test_output.txt"
:echo %0, %1, %2, %3, %4, %5, %6, %7, %8 >> "n:\temp\test_output.txt" 
:date /T >> "n:\temp\test_output.txt"
:time /t >> "n:\temp\test_output.txt"

set SNMPAGENTHOST=10.2.192.32
set SNMPAGENTPORT=162
set TRAPOID=1.3.6.1.4.1.27389.1.2
set OID=1.3.6.1.4.1.27389.1.1
set SNMPCOMMUNITY=public

Dear wsnyder.

I see that the backslashes are missing. In some cases I could figure out which ones but could you send me a pm with the original script? Would be nice,

thanks
