Commands to run on client

share <local_file_path> <filename>.<file_extension>.mtorrent

• it will share the data with tracker and put your client in seeding mode. So that other clients can access them by using the mtorrent file that you generated.

get <path_to_.mtorrent_file> <destination_path>

• it will get metadata from tracker and starts downloading file in the destination path.

remove <filename.mtorrent>

• it will remove the metadata entries from server and destroys mtorrent file from client.

• File is shared by only one peer now (First peer in the list).
• Whenever client starts, it scans current working directory ans update server about that files.
