Building a Intra Home Network by cross cabling.

It was had been years that i had been using PC and which gone quite old and that was the time i felt to buy a latest one.
Everthing went fine i bought a brand new PC home with whatever the later configuration that i could get till date.but then came the question.., what am i going to do with my old pc??, Im i going to through it away ???... definitely that is not a better option as still being old my old machine works great.. with a Intel p IV processor and a 1GB ram and 80HDD,dvd writer.., everthing well and good.Then came the idea how about putting my new pcs into a network and play around a little of network stuff and learn a little bit of how we can hack on machines.. :D.
Then i was searching on alternatives.., i found that simple cross cabling would be the best option since it only requires a crossed ethernet wire with a little pc configuration and nothing else.You really save a lot of money by not buying a router for this purpose.
Use can use a thus formed network as a LAN and also for Internet sharing.
Here i give the simple steps how to build a intra home network in the linked doc
