[SNMP4J] Trap sending from snmp4j agent problem

[Jothi P Neelamegam]

I was wrong, actually you do not need to be a super user to send traps 
to a remote machine, you just need to be a super user to bind to 
privileged ports...

I use the same syntax and it works for me in Linux. Is  your remote 
system reachable from your agent?
