linux-net _might_ be more appropriate.

Just a few thoughts:

Have you tried connecting them directly via a crossover cable?

Are they definitely connected via a hub, and not a switch?

Maybe one of the cards is jabbering, causing a lot of packet loss,
which is only noticable when transfering between local machines?

What happens when both machines make an ftp connection to a host on
the internet?
