The SNMP response packet really only have one problem that I can see.
The community string 'public' is being included in the response, but
it's length field is incorrect (01 instead of 06). That throws off the
rest of the packet (which seems to parse fine once you fix the community
string length).
You'll have to check the code to see why the community string length is
wrong?
