Hi,
I'm writing a program to assist in learning/debugging tcp stacks, it creates a raw socket and replicates an exceedingly simple tcp stack. By which I mean, it sends and receives packets, setting correct flags, payloads etc.
One difficulty I've come across, after I've created a raw socket and sent my syn packet, when the syn+ack packet arrives from the peer, my program receives it fine - but the kernel also resets the connection.
You might be able to use the tun/tap device. It basically creates a network interface with a file descriptor of your program being the other side of it. See Documentation/networking/tuntap.txt (in the kernel source) for more details. Is this an option for you? -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com
