Thanks but that doesn't seem to be the problem. The cards are fine, the
diagnostics say they are up and running, the 100Mb lights are on, I can
see arp packets saying "who-has x please tell y". The problem is neither
machine can find the other. The wierd thing is that before and after I run
the network restart command the routing tables are *exactly* the same. As
you would expect, but the behaviour is as though some routing information
has changed.

I tried that anyway and it seemed to make things worse. There was no luck
after ifup-eth0 so I put things back as they were.
