I having been using your project for downloading torrent on my server for a couple of weeks now and it works very well. Thanks for your contribution! I used to use a simple HTTP file server to retrieve the downloaded files to my computer. As I used this cumbersome approach heavily on a daily basis, I began to implement a tool to download torrent efficiently just by running a local command with the magnet link which sends torrent download request to the server. You may find my current working prototype sloppy but please check out my project.

torrent
This repository implements BitTorrent-related packages and command-line utilities in Go. The emphasis is on use as a library from other projects. It's been used 24/7 in production by a downstream, private service since late 2014.
There is support for protocol encryption, DHT, PEX, uTP, and various extensions. See the package documentation for a more complete list. There are several data storage backends provided: blob, file, and mmap, and you can write your own, such as to store data on S3, or in a database. You can use the provided binaries in ./cmd, or use package torrent as a library for your own applications.
Many of the sub-packages can be used for other purposes: bencode, and tracker, in particular.
Installation
Install the library package with go get github.com/anacrolix/torrent, or the provided cmds with go get github.com/anacrolix/torrent/cmd/....
Library example
There is a small example in the package documentation.
Other public projects using torrent
- Go Peerflix
- Cloud Torrent
- Android Torrent Client
- Android libtorrent
- Trickl - Torrent Client
- Confluence
- Remote-Torrent
Commands
Here I'll describe what some of the provided commands in ./cmd do.
Note that the godo command which is invoked in the following examples builds and executes a Go import path, like go run. It's easier to use this convention than to spell out the install/invoke cycle for every single example.
torrent
Downloads torrents from the command-line. This first example does not use godo.
$ go get github.com/anacrolix/torrent/cmd/torrent
# Now 'torrent' should be in $GOPATH/bin, which should be in $PATH.
$ torrent 'magnet:?xt=urn:btih:KRWPCX3SJUM4IMM4YF5RPHL6ANPYTQPU'

torrentfs
torrentfs mounts a FUSE filesystem at -mountDir. The contents are the torrents described by the torrent files and magnet links at -metainfoDir. Data for read requests is fetched only as required from the torrent network, and stored at -downloadDir.
$ mkdir mnt torrents
$ godo github.com/anacrolix/torrent/cmd/torrentfs -mountDir=mnt -metainfoDir=torrents &
$ cd torrents
$ wget http://releases.ubuntu.com/14.04.2/ubuntu-14.04.2-desktop-amd64.iso.torrent
