Hi,
I've been doing some searching on a library that allows you to manipulate
the headers of TCP, IP and UDP packets. The ones I've been able to find (in
java.net I believe - Datagram and Socket) only allow TCP and UDP access, but
neither allows for manipulation of the sender IP, ACK and Seq values (for
TCP). I also haven't been able to find one for the Internet Protocol (IP).
I'm taking a networking course and need to access these values for some
class assignments and research that I want to do.
Any pointers would be greatly appreciated.
Thanks.
Adam

Java isn't a good choice of language for that.

Ok, thanks. Back to C I guess ;)

Have a look at http://jswrench.sourceforge.net. The project has some C++ but
the packet manipulation is handled in Java.

Just took a quick peek at some of the source code and it looks like it is
exactly what I need. Thanks!
