With a 10 Mbps hub, you can easily get collisions when several computers 
send packets at the same time, so this is not a good testing environment. 
You should probably get a switch or connect the source of packets and the 
target directly with a crossover cable.

I think that this is not really a vortex specific question, so you might 
find better results asking on linux-net mailing list.
