At home here I have a notebook and desktop PC and I can connect between them via a hub and everything works but when I try a crossover cable instead I get one way transmission, from the desktop to the notebook.
Thinking it could be a cable fault I connected the cable the other way found (so the pairs in use were the opposite way round) but still the notebook could see packets coming from the desktop and not the other way round.
Does anyone have any tips?
yeah crossover cables are not actually supposed to work, they do by virtue of having the correct wires in the correct place but they are not supposed to work. I would give you the exact reasons if i had my Ethernet book at home but its at work where i have been "fixing" ethernet things there.
also did you try tcpdump on both ends to just to make sure things couldn't be seen? and are you sure that one of the cards isn't autonegotiating 10 base and the other 100 when you are using the crossover cable?
