[SNMP4J] Null value in Variable Binding

[Tim Brown]

Hi,

 

Regardless of the OID specified I seem to get the same response back
every time.

The response is always:

 

RESPONSE[requestID=2107916581, errorStatus=Success(0), errorIndex=0,
VBS[1.3.6.1.2.1.1.1.0 = Hardware: x86 Family 15 Model 4 Stepping 3 AT/AT
COMPATIBLE - Software: Windows Version 5.2 (Build 3790 Multiprocessor
Free)]]

 

When I check the Variable Binding specified it comes back with the value
specified for the OID and "= Null".

For example 0.1.2 = Null

 

Any suggestions would be greatly appreciated.

Cheers,

 

Tim
