Make your own Straight or Crossover cable(s)
This is just a short tutorial showing the layout of how standard cable and crossover(null-modem cable) cables are made and the differences between them.
These cables can be purchased at any computer store but why spend the money to buy premade cables while you can make or repair the cables at home or where ever you may be at the time.
Cross over cable
This used when you need to connect two computers together, if a hub is not available at the time, other uses for this cable are connecting two hubs or switches together.
To make this cable one end has to be setup as shown in the crossover layout and the other end has to be the standard layout
Standard cable
This is used for connecting to routers, hubs and switches, cable modem Etc.
To make this cable both ends are the same as shown in the standard layout
List of tools and items you will need
A box of RJ45 connectors( these can be picked up at pretty much any computer store)
A RJ45 crimper (same as above I highly recomend using a crimper instead of using a pair of plyers and a flat screw driver less chance of messing up the connector and having to start over again.)
Cat5 cable (same as above)
What you need to do to get started
Strip about 1" inch of the outter jacket off of the cable being careful not to nick the wires on the inside
Next untwist all the wires so it will be easier to arrange them in the proper order.
Wire standard 568B

(A good habbit to get into doing, is to double check to make sure that the wires reach the copper or brass connectors at the end and that order of the wires are in the proper order before you crimp the connector.
Happy crimping

Ah yes, I had to learn how to do this in my Adv. LAN class, and it took forever. I still have my first self-made crossover cable sitting proudly in my room.

Probalby not. Its probably just where they finally got some hands on.
For a while there... its all text book stuff. Need to know but not much fun.
I think we covered that in semester one or two of the Cisco Academy.
Quitmzilla is a firefox extension that gives you stats on how long you have quit smoking, how much money you\'ve saved, how much you haven\'t smoked and recent milestones. Very helpful for people who quit smoking and used to smoke at their computers... Helps out with the urges.
