Update 4-5-09: Added another youtube video explaining Utorrent options more in depth.
I love Bittorrent. Bittorrent is an extremely efficient method of using P2P technology to distribute files across the Internet to the masses. This post is not a lesson on the technology behind bittorrent. Instead, I am going to show you what you need and how you can start finding software (among other things) on the Internet. Please note that Bittorrent itself is a legal medium, but the content that you download with Bittorrent may not. This is a tool, and I am not held responsible for how you use it.
Need a Bittorrent client. I recommend utorrent. Find it at www.utorrent.com
Get the latest version. After installing it, it will look like the screen shot below:
Now afterwards you need what is considered a Torrent file. This is a small 1kb file that tells your Bittorrent client how to download the file. If you go to http://www.torrentz.com and search for Ubuntu, you will see many links. I happened to find a link and download it off of mininova.org.
After you add it to your torrent client, the file will start downloading. Once the file finishes downloading, you can then decide what you want to do whether that is install the program, or burn it to a disc.
What is important to achieve faster Bittorrent speeds is to enable the ports on your router. For a good guide on this, go to www.portforward.com and find the utorrent guide for your router.
When you go to the speed guide in Utorrent, you can specify a manual port:
To see a video of this in action, watch my video below for a quick tutorial on how to setup yourself for Bittorrent usage and port forwarding.
Below is another video going into some of the other utorrent options.
