We know we could find almost anything by using torrent. Either it is legal or not. So, here is your Torrent 101. Credit goes to the author : http://www.bittorrentguide.co.uk/torrentguide.html

Introduction

Bit torrent by definition is just a file
transfer protocol. A Bit Torrent client is the application which uses
that protocol. A list of clients can be found here.
You can use BitTorrent to share and download any type of file you want.


First of all, you need a bit torrent client - I use µTorrent - it has lots of cool features and uses very little resource.

BitTorrent Jargon & Language Explained
Next you need to understand the language
and how it works. Here's a rough translation:


Seeder = the one(s) with the file
A seeder is uploading, to get a file you need at least 1 seed in the
swarm

Leecher = the one(s) without the file (also known as a peer)

A leecher is downloading from a seeder (and most of the time is also
uploading to other peers/leechers too)

Tracker = the thing that keeps track of who has what and what pieces
There are many trackers out there, some public and some private

Swarm = the group of computers involved with any one particular
torrent.

The number of computers that the swarm contains is found by adding the
number of seeds to the number of peers.

Ratio = the amount you have downloaded compared to the amount you have
uploaded. Also referred to as your stats. If you use Bit Torrent you
MUST upload/seed as much as you download/leech - read more here

Reseed = asking someone to repost a torrent that has no seeds


Client = the program you use to download Bit Torrent's

How Does It Work?
Lets take soulseek to start with as that
is a format most P2P users are familiar with. You have a file and I
want it. I get in the queue and wait for the others in front of me to
download it, then I get a turn. Needless to say, there can be some
quite big queues!


Now lets look at how Bit Torrent works.

First of all, imagine I have a book, with 100 pages, and 10 people want
it. I give 10 pages to each person, and between them they have the
whole book. I can then drop out of the file exchange and leave them to
copy bits between themselves until they all have the full book.

It works the same with files. The file being shared is broken up into
smaller pieces. The tracker keeps track of who has what pieces and helps
those looking for pieces to get them, while helping those with the
pieces share them out to those looking.

I Have My Client Installed, What's next?
The files you download are .torrent files
and they are tiny in size (just a few Kbs). The .torrent just contains
information concerning what the file is, how many pieces it has and what
tracker it's going through. When you click on a .torrent file, you then
chose to open it with your bit torrent client (azureus). You then
select your place to save it and your download will begin (hopefully).

In order to get a download - you need seed(ers). Sometimes the tracker
might be down, in which case no one knows who else has the file and it
doesn't work.


A download with lots of seeds and only a few peers will generally be
quick, if you have lots of peers and no seeds it will generally be slow.

How Does BitTorrent Compare To Other P2P?
The main benefit of torrents is its
versatility. Because BitTorrent is just a protocol, a way of sharing
files, there is no restriction on the type of file you can share. It's
popularity also means that you have a wide range of torrents available
and the latest releases too.

The big differences with Torrents compared to other P2P networks are:


a) I don't have to give the whole file to each person to get it out
there - I can give a bit to each person

b) Once I have given a bit out, it's availability has just increased,
because someone else can then also give it out, and so on and so on.
the speed of a torrent will generally get better as more and more
people want it - unlike SoulSeek or other P2P apps where you just wait
longer to get it!!

c) Torrents technically aren't illegal. After all, a torrent is just a
tiny little file with no copyrighted content. It's a bit muddy water
here though, as they can facilitate the transfer of copyrighted content.


If you want to know some sites to get torrents from I have got a few
listed here

How Do I Configure My Firewall For BitTorrent?
There are two types of Firewall, a Software Firewall and a Hardware Firewall, like a router for example.
Both will need to be configured in order for you to use BitTorrent.


Why?

BitTorrent relies on two basic types of connection to share files, those
made by other people asking you for something are called Incoming or
Local Connection, and when you initiate a connection with someone else,
you are making an Outgoing or Remote Connection.

However, a firewall will automatically block an incoming connection in
case it is harmful. So in order to be able to accept BitTorrent files
from other people, you need to tell your firewall to accept these
connections.


How?

Hardware Firewalls and Routers
Routers have what is called NAT - Network Address Translation. Put
simply it means that it will block all incoming connection attempts
unless it is told otherwise. This means you need to open some ports. But
you also need to do more than that, you also need to forward the ports.
This is where the 'Translation' bit comes in.

Your router has 'ownership' of your (real) WAN* IP address and each PC
connected to it is issued with a LAN** IP address. You need to tell the
router that when traffic comes in on a certain port or port range it
should let through and send it to your PC's LAN IP.
Here is a visual guide on how I set up my Router - it should help.


Static IP
You will also need to set up a static IP address. As mentioned, the
router issues each PC connected to it with a LAN IP address. This can
change however, for example when you reboot your PC.

Imagine that your pc has the LAN IP of 192.1.11.23. So you forward the
BitTorrent ports to 192.1.11.23. Then you reboot your machine and when
it comes back on, its LAN IP has changed to 192.1.11.24. Your port
forwarding isn't going to work anymore as the ports aren't being
forwarded to your PC anymore.

This is why you need to set up a Static IP, it gives your PC it's own
permanent LAN IP. It'll never change, so the port forwarding will work!


Step by step instructions on how to set up a static IP are here.

Remember to do it on every pc that connects to the network.
*WAN = Wide Area Network - the internet basically
**LAN = Local Area Network - your internal network of PC's


This website will help you configure your router and set up a static IP. It covers
nearly all of the routers available and also provides step by step
instructions for common applications.

Software Firewalls
A software firewall will work one of two ways, it will either imitate a
hardware firewall and block all traffic on all ports unless told
otherwise; or it will only allow specified applications access to the
internet. The Windows XP firewall works on port configurations, and
something like Zone Alarm works by granting programs access.
A guide for Windows Firewall can be found here.


When using something like Zone Alarm, you just need to give your
BitTorrent Client (for example Azureus) permission to access the
internet. If you do use Azureus, then you will also have to give Java
(C:\Program Files\Java\Build Version\Javaw.exe) access. Remember to give
any subsequent Java updates access too!

What ports should I use?
The default ports are 6881-6889. But that does not mean to say that you
have to or should use them. Some ISP's throttle bandwidth on these
ports, and some trackers have banned them because of that. So choose 10
ports of your own (10 is enough) between 50,000 and 60,000. This is
considered to be a safe zone and any 10 ports you choose should not
already be in use.

In order to change the ports all you need to do is choose 10 ports. Now
open them up in your router or firewall as covered above, and then
change the settings in your client to reflect the new ports being used.
Each client is different so I can't really go into detail here.

Some Important Things To Remember
IN ORDER TO KEEP THE TORRENT ALIVE AND
ALLOW OTHERS TO DOWNLOAD YOU MUST CARRY ON SEEDING TO AT LEAST 1:1
RATIO.
Once you have the file, it's no good just closing your
client and forgetting about it. In order to allow it to be shared for
others you MUST continue to seed. Most trackers keep an eye on your
download to upload ratio and those just downloading and running get
booted. You will not get far unless you heed this rule.

You are not invisible when you are in a swarm. Others, including
copyright owners if they so wished, can see your IP when you are
downloading or uploading a file. Learn more here.



If you use a torrent site which has a forum attached, take the time to
say thanks to the poster of the torrent. It only takes a moment.

Torrent sites and torrents themselves die. They go up and down quicker
than a whores draws. Just the nature of the beast. If no one is
seeding, you can't have it. You can also only have what is on offer.

The speed at which you download is determined by things such as the Seed
to Peer ratio, the seed(ers) upload bandwidth and of course your
available download bandwidth. Try to download torrents that have lots of
seeders and few peers in order to get faster speeds.
