Recently, I wanted to download CentOS image, but owing to the large file I thought torrent download would be easier. But my service provider doesn’t allow torrent connection. So, what’s the solution?

Luckily we have transmission torrent client which can be installed on any Linux server. Fun fact is that you need not necessarily buy new Linux server for transmission client. You can install it along side with your application without any issue at all. Just in case if you don’t have any Linux server, then check out this VPS hosting which charges $1/month.

If you look at online torrent downloader, they charge you from $5 per month onwards for unlimited download and unlimited file size. With your own server you have full freedom to download as many torrent as you want and download speed will drive you crazy.

So, let’s begin building your own torrent downloader using transmission client. First of all you need to identify your Linux OS and then follow the guide accordingly.

sudo service transmission-daemon stop

Next edit the settings file to make following changes

sudo nano /var/lib/transmission-daemon/info/settings.json
