[SNMP4J] Debugging Agent

Mon Mar 20 21:30:50 CET 2006

Hi Frank,

I am still plugging away at getting a "Hello World" agent to work.  I
have liberally sprinkled log messages throughout the code to see where I
can catch things.

When I try to hit it with Net-SNMP's snmpwalk, I get the following:

$ snmpwalk 127.0.0.1

snmpwalk: No response arrived before timeout.

Do you have any ideas for debugging the agent to see if it is receiving
anything?

Thanks in advance,

Oleg

The (test) agent seems to start on Windows with the following messages:
