public class SnmpD

extends java.lang.Object

implements org.opennms.protocols.snmp.SnmpAgentHandler

SnmpD implements a sample SNMP daemon. It listens for messages received from remote agents on (default) port 161. It is based on Bob Snider's adaptation of JoeSNMP's TrapD test class, which is a part of the OpenNMS project. Thanks go out to Bob, Brian and the rest of the OpenNMS crew for their excellent work.
