Are you using TCP, UDP, or some completely different protocol
entirely? Also, can you get a network trace of the packet in
One way to get such a trace is to run this command (as root) on your
linux box before starting the embedded Dos client:
tcpdump -i eth0 -s 5000 -x > outfile.txt
(replace eth0 with the appropriate interface name) Then, after your
client runs, interrupt this with a Ctrl-C and edit outfile.txt down to
only the relevant packet.

More details about the packet in question could at the very least
narrow this down to which part of the kernel is responsible.
