Then they're running at half-duplex only.

Well, if there's no heavy load on the ethernet segment in
both directions, you might not notice that the duplex
setting is wrong.

Look at the output of ``netstat -i''.  The last column
(number of collisions) should be zero for a full-duplex
connection.  I guess it is non-zero in your case, unless
there is really not much traffic on that line.
