Yep, you need a crossover cable.  The crossing is taken care of when you use a 
hub or a switch, but when you connect two devices directly, you need to cross 
over the send line from one box to the receive line of the other.

If you look at the ends of the standard ethernet cable, you should see a 
pattern something like this.

  **end1**            **end2**
orange stripe  --   orange stripe
orange solid   --   orange solid
green stripe   --   green stripe
blue solid     --   blue solid
blue stripe    --   blue stripe
green solid    --   green solid
brown stripe   --   brown stripe
brown solid    --   brown solid


A crossover looks like this:

  **end1**            **end2**
orange stripe  --   green stripe
orange solid   --   green solid
green stripe   --   orange stripe
blue solid     --   blue solid
blue stripe    --   blue stripe
green solid    --   orange solid
brown stripe   --   brown stripe
brown solid    --   brown solid


blue and brown are not used in the ethernet setup, so you can ignore them.  
You can buy them or make them yourself if you have a crimper, or know of 
someone that does.  Or, the simplest route is just to buy a simple four port 
switch and be done with it.

It thinks the cable is unplugged because it's listen end is plugged into the 
listen end of the other machine instead of the send end.  Kind of like having 
two people on the phone with no one talking.  Both callers can't tell if 
there is someone on the other end of the line.  The crossover cables will 
solve this problem
