[SNMP4J] problem to receive traps

[Frank Fock]

Hello Stefan,

You did not specify the interface and port on which you want
to receive SNMP messsages. SNMP4J therefore chooses an arbitrary
one. Have you sent the traps to that port?

If you have used

this.snmp = new Snmp(new DefaultUdpTransportMapping());

by accident, then please specify the port like this

    Address listenAddress = GenericAddress.parse("udp:0.0.0.0/162");
    TransportMapping transport =
	new DefaultUdpTransportMapping(listenAddress);
    snmp = new Snmp(transport);

BTW, I will make the JavaDoc clearer in this point for the next
release.

Best regards,
Frank
