[Java] Reading from an already open socket

[Lance]

How can I listen to a socket opened by another program? Let's say I just logged on BNET with JavaOP2 and I received the ENTERCHAT packet. I want to view the contents of that packet in my program x3

There is no way to do this through the Java API. You could write a JNI library to utilize a packet logging library such as WinPcap (for Windows) or similar.

Other than that, you can do a man-in-the-middle attack, where you write a program that acts as a proxy for the BNCS connection.

Or just modify JavaOP since you have the source ;)

Yeah, I believe this would be the quickest way. If you want the information dynamically, I suppose you could set up a port on localhost to which you forward the stuff that you want from JavaOp, and then listen to that port on localhost with your program. Of course if it's just a single packet then you could write to a file.

Though I wonder why you're doing this in the first place... and I wonder why I'm posting four days later...
