snmp agent -- Error status = noSuchName, index = 1.

[Adrian John Cahill]

Hi,
    I am haing a bit of trouble with the snmp agent in Erlang. If i try
to send a request to the agent, i get the following error:
3> snmp_mgr:gn([[1,3]]).
ok
* Got PDU: v1, CommunityName = "all-rights"
*!*!* An error occured. *!*!*
Error status = noSuchName, index = 1.
Response,         Request Id:79933850
  [1,3] = 'NULL'



I turned on verbose error messages in the agent window, and it displays
the following error:

I noticed that it says target_v3, i have the agent set up for snmp v1, i
have tried snmp v1&2&3 but i get the exact same error message.
I do not know how to progress this any further, if anyone has any
suggestions i would be delighted.
