Hi Emmanuel,

Be sure you are using a cross over cable. You can't use a normal cable
between the two NIC cards (unless the NIC cards are connected via a
hub or switch). 

Also, be sure that your routing table entries match whatever reality
is. Use the 'netstat -r' command to check. If you are not sure, post
the output from both machines, and tell us exactly what you have (i.e
is it a cable from laptop to desktop and that is all, or do you have a
cable/DSL modem somewhere with a hub?). 

On each machine you will need a route to the other (the exact details
will be base don if there is a router or other default gateway
somewhere in your network), or you will need a router that knows how
to get from one to the other.

Cheers!
