Hi all,

This is Saurabh and i am unable to get the response pdu. To check whether
through any oid it returns something or not I am using JMIB browser and for
any oid it shows received record as 0(zero).  I am trying by increasing
timeout time of UserTarget, but still it not works. Attached is the code
snippet.
