  There are a number of possible causes of this.

  The most likely are the agent access control settings (who is allowed
  access by the agent itself), or firewall/packet filtering settings
                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  A fuller list of possible causes (with indications of how to check
  for each) is as follows:

        - are the requests arriving, or being blocked (e.g. by a firewall)?
                (Restart the agent using 'snmpd -f -Le -d'
                 and see if it shows the incoming packet dumps)


My guess is that you're most likely running 'iptables' (or similar)
and that this is blocking external access to port 161.
  If not, then try working through the full checklist from that FAQ entry.

Please note that 'snmpd' is run as a standalone daemon, and is *not*
typically under the control of xinetd.
