[SNMP4J] (no subject) IpAddress vs. UdpAddress

[RobertoBouza at bayviewfinancial.com]

Frank,

Thank you. I appreciate your prompt answer.

Now I'm facing something else... I'm getting this:

org.snmp4j.MessageException: Message processing model 3 returned error: 
-1402
        at org.snmp4j.MessageDispatcherImpl.sendPdu(Unknown Source)
        at org.snmp4j.Snmp.sendMessage(Unknown Source)
        at org.snmp4j.Snmp.send(Unknown Source)
        at org.snmp4j.Snmp.send(Unknown Source)
        at GetMIBValue.main(GetMIBValue.java:60)

I trying to figure out what that error means but no clue at all. It looks 
like the source is incorrect maybe I need to add the source TCP address to 
the transport?

Thank you again.

Hi,

You cannot communicate with an IpAddress as communication
endpoint. You need either an UdpAddress (default) or
a TcpAddress. IP is a network protocol, whereas UDP and TCP
are transport protocols.

Best regards,
Frank
