[snmp] TrapPduv1.getIpAddress() returns negative values

[Birgit Arkesteijn]

Hi Jordi,

I've never seen this behaviour before.

I just run the snmpv1 examples ReceiveTrap (on one machine) & SendTrap
(on the other machine) against each other, using jdk 1.4 on Linux,
successfully.

run 1:
trap id 1, v SNMPv1 from host 192.67.4.53, sent from port 33504

run 2:
raw pdu v SNMPv1 from host 192.67.4.53, sent from port 33504


Which platform do you run the stack?
Which jdk do you use?

Which IP address are you talking about?
- the TrapPduv1.getIpAddress() 
- TrapEvent.getPdu().getContext().getHost()
- something else
What do you use to print the IP address?

Cheers, Birgit
