Many of our readers have wanted to dive into the world of P2P (Person-To-Person) file sharing so we decided to put together a high-level guide to get started. We think building a solid BitTorrent machine is easier than most people think.  Of course there are some confusing issues such as “Which client should I use?” Or, “Which ports work best?” that might stump even the most advanced computer user.  We wanted to put together a quick guide as to how to build a low-cost BitTorrent machine. BitTorrent is just a way to transfer files and multimedia of any size easily.  The BitTorrent process basically breaks up a file or group of files in to small pieces to be transferred over the net to someone else with a BitTorrent client who has requested that file. The “peers” who are interested in your file download small pieces of the files bit by bit. When there are many peers who have the same file, they share the file so that a client who has requested this file can download from multiple sources at a time.  As more peers share (or “seed”) the same file, the download becomes easier and faster using essentially less bandwidth for the seeders.  Because you aren’t relying on one particular individual or server to send you information, P2P BitTorrent is a great way to share large files over the internet – especially if the file is a popular one.
