Java APIs

Hi!

I have written a piece of software that can read snoop files and replay them. To give a little more understanding on the topic, I can say that we snoop SNMP traffic (UDP) and then we can recreate the scenario in a lab environment but with the lab environments IP numbers.

Previously, we have done this with JPcap (http://netresearch.ics.uci.edu/kfujii/jpcap/doc/index.html) but I want to see if it is possible to do with using only the Java 6 API.

Reading and parsing snoop files is already sorted, but the problem is changing the IP number to anything I want.

The frame I have is an ethernet frame. I have all this in byte form. Of course, I can change the IP number in the byte array, but how do I send the byte array?

I have a "half-way" solution now, where I use java.net.DatagramPacket and use the UDP contents from the ethernet frame and put that in the DatagramPacket, but I really need to be able to change the IP number.

Can I do thins with Java 6 API?

Thanks for any input!
