The other day, I asked a friend for some pictures of a concert and wedding that we both attended. Normally, for smaller files, he’d just send me what I wanted through Skype. However, as anyone who uses Skype will tell you, peer-to-peer transfer speed in the program is abysmal. Not wanting to set him up a FTP account to my website, I suggested that we make the transfer using BitTorrent. Assuming that you are using uTorrent and have the appropriate exceptions already declared in your firewall, here are the steps that you can take to share files between you and your friends:
- Figure out your Internet IP address. If you don’t know what yours currently is, try http://whatismyip.com/.
- Figure out what port uTorrent is using. Your current port can be found in the Options –> Speed Guide menu.
- In uTorrent, go to File –> Create New Torrent
- Select the file or folder that you would like to share
- In the trackers section, add the following:
- Under “Other” select “Start Seeding”
- Click the “Create and save as…” button.
- Save the torrent file to your disk
- Send the torrent file to your friend
- Have your friend open the torrent
Some of you may be asking why we added the local machine (localhost) as a tracker in step #5. Some routers act goofy and don’t forward data properly when you attempt to access the router’s Internet address from the local network. Because of this, your friend will be able to connect to your machine, but you won’t! In other words, “localhost” is for you and your Internet IP address is for your friends.
As an aside, we found that sharing a folder transferred significantly faster than the same folder compressed into a zip file. Sharing a zip file, we achieved a download rate of approximately 10 kbps. With the folder, my friend and I were able to achieve a sustained download rate of approximately 60 kbps. Not too shabby!
