First do not send me an email directly .. send it through net-snmp users
community so others can help you and learn from the messages.


Try this:

snmptrap  -v  1  -m ALL -c  public localhost .1.3.6.1.6.3  localhost 6 1
20071105

Actually the syntax is

snmptrap -v 1  -c <community> manager_address OID agent_address <reasion for
sending trap> <trap-type> <Time stamp>

snmptrap -v 2c -c <community> manager_address <Time stamp> Trap OID

First run your snmptrapd in a shell then from other shell try to send
snmptrap...

If you still had a problem then send us what messages you are getting after
executing snmptrapd and snmptrap
