How To Create A Torrent Using Mktorrent

Creating a torrent

• To make a .torrent file using command line, execute this command:

mktorrent -v -p -a http://tracker.url -o filename.torrent folder_name

-v is for verbose -p is for private, as in not DTH or PeerExchange -a is for tracker url follows -o is for output file name follows .

• Important! The command needs to be all in one line, and quotes must be used around the folder name if it contains spaces.

• For example, if I wanted to make a torrent for What.cd from the data in the "VA – Summer Trance 2009" directory I already have on my server at ~/torrents/completed/VA - Summer Trance 2009, you would navigate to the parent directory to make your torrent. Type to navigate to it:

cd ~/torrents/completed

Then type the following command:

mktorrent -v -p -a http://tracker.what.cd:34000/xxxXXXxxx/announce -o VA-Summer_Trance_2009.torrent "VA - Summer Trance 2009"

Please note that you must use quotes if the target dir name contains spaces.

If you want to specify piece size for torrent, you can use -l switch (small L) it's in potency of 2 so:

2¹⁹ = 524 288 = 512 KiB for filesizes between 512 MiB - 1024 MiB

2²⁰ = 1 048 576 = 1024 KiB for filesizes between 1 GiB - 2 GiB

2²¹ = 2 097 152 = 2048 KiB for filesizes between 2 GiB - 4 GiB

2²² = 4 194 304 = 4096 KiB for filesizes between 4 GiB - 8 GiB

2²³ = 8 388 608 = 8192 KiB for filesizes between 8 GiB - 16 GiB

2²⁴ = 16 777 216 = 16384 KiB for filesizes between 16 GiB - 512 GiB This is the max you should ever have to use.

2²⁵ = 33 554 432 = 32768 KiB (note that utorrent versions before 3.x CANNOT load torrents with this or higher piece-size)

Usage:

mktorrent -v -p -l 19 -a http://exampletracker.com/announce -o filename.torrent folder_name
