Torrent is file distribution system using which a file is downloaded part by part from different server and assembled in to one at the client side. This is a popularly used method to share files across network. There are many advantages for this method like its not centralized so there is no single server which takes all the load and slows down. Then there is this seeders and leechers. The seeders are then one who deliver the files to the request and the leecher are the one who download the files part by part. The leechers will eventually become seeder by seeding the parts of the file which they already downloaded from the seeders. The disadvantage of this method is that you need to keep your PC always on and running and this is a lot of power. We can change this by using an Orange Pi Zero as a torrent box. For that you need.
apt-get install transmission-daemon
Now after installing the transmission daemon stop it before editing the configuration
/etc/init.d/transmission-daemon stop or systemctl stop transmission-daemon.service
Now change the following lines as follows
"rpc-authentication-required": true, to "rpc-authentication-required": false, #This will disable to login authentication "rpc-whitelist": "127.0.0.1", to "rpc-whitelist": "127.0.0.1,192.168.2.*", Here the I have used the IP address range of my network, use your IP network range here. This will allow only device in the subnet.
Now start the trasmission daemon
/etc/init.d/transmission-daemon start or systemctl start transmission-daemon.service
Now in your PC or Smartphone browser type the Ipaddress of the Orange Pi with 9091 port.
You can change the port no from 9091 to something else in the configuration.You can see below I am downloading different versions of Debian ISO.
