Slow transfer times between XP/Linux direct connection

[curvedvision]

Hi,

I've a problem with network routing which is beginning to drive me crazy!

I basically have two PCs, one which is running Windows XP Pro, and another which is running Ubuntu 7.10. Both have USB wireless adapters connected to them, plus a crossover ethernet cable attached to their ethernet network interfaces linking the two machines together.

My end result is to have any traffic between these two machines travel over the ethernet interfaces, but any other network traffic to travel over the wireless interfaces. To simplify things for the time being, I have downed both of the wireless interfaces and am concentrating solely on the ethernet connection (192.168.0.20 (Windows) and 192.168.0.21 (Linux)).

I have Samba installed upon the linux box to export a directory which is then mapped within XP to a particular driver letter. Unfortunately, copying any files from the linux box over to the Windows box takes absolutely ages - for example a 52MB directory is taking roughly 150 seconds to transfer!

I have attempted to setup the networking routes for this connection but from that very slow transfer time I'm guessing that I've done something wrong. If someone could take a look at the details below and point out any obvious problems, or if they have any suggestions as to something else that could be causing the delay, then that would be very helpful.

Thanks, Neil
