[CLUE-Tech] Oh yea!

For a cross over, reverse the pairing (input vs output) on one end of 
the cable.

To follow spec (if you care,) Ethernet should be wired to the TIA568B 
standard, color order is:

1) White-Orange
2) Orange
3) White-Green
4) Blue
5) White-Blue
6) Green
7) White-Brown
8) Brown

Ethernet uses the Orange and Green pairs in 568B.  A quick check when 
looking at a modular RJ-45 mail will have a white-color alternating 
pattern over-all, even with the split green pair.

Make sure you crimp and punch *very well*.  One of the most frustrating 
things in the world is to have one conductor be not quite connected.
