bttrack.bittornado(1) General Commands Manual bttrack.bittornado(1)


bttrack — bittorrent tracker


bttrack [options ...] --dfile file


This manual page documents briefly the bttrack command.

This manual page was written for the Debian distribution because the original program does not have a manual page.

bttrack is a "tracker" for bittorrent clients. This program keeps track of the completion of each client, and communicates that information when requested to other clients.

There is one required option, --dfile, which specifies what file to store the recent downloader information.


These programs follow the usual GNU command line syntax, with long options starting with two dashes (`--'). A summary of options is included below.

the file to store the recent downloader information (required)
the port to listen on (defaults to 80)
a comma-separated list of ips and hostnames to bind to locally (defaults to '')
whether to allow the tracker to connect to peers via IPv6 (defaults to 0)
whether an IPv6 server socket will also field IPv4 connections (defaults to 0)
then number of seconds to use as a timeout for closing connections (defaults to 15)
the number of seconds between saving the dfile (defaults to 300)
the number of seconds between expiring downloaders (defaults to 2700)
the number of seconds downloaders should wait between reannouncements (defaults to 1800)
the num of peers to send in an info message (defaults to 50)
the number of seconds to wait between checking if any connections have timed out (defaults to 5)
check num times if a downloader is behind a NAT (0 = don't check) (defaults to 3)
whether to add entries to the log for nat-check results (defaults to 0)
the minimum number of seconds it must have been since the last flush to do another one (defaults to 3.0)
the minimum number of seconds before a cache is considered stale and is flushed (defaults to 600.0)
only allow downloads for torrents in this directory (defaults to '')
only allow downloads for hashes in this file (hex format, one per line), cannot be used with allowed_dir (defaults to '')
whether to allow special keys in torrents in the allowed_dir to affect tracker access (defaults to 0)
whether to enable multitracker operation (defaults to 0)
whether to allow incoming tracker announces (can be none, autodetect or all) (defaults to 'autodetect')
number of seconds between outgoing tracker announces (defaults to 120)
the num of peers to get in a tracker announce (defaults to 20)
if set, forwards all non-multitracker to this url with this optional password (defaults to '')
whether to act as a data aggregator rather than a tracker. If enabled, may be 1, or password; if password is set, then an incoming password is required for access (defaults to '0')
whether to reopen the log file upon receipt of HUP signal (defaults to 0)
number of seconds to wait before assuming that an http connection has timed out (defaults to 60)
number of seconds between reloading of allowed_dir (defaults to 60)
whether to display an info page when the tracker's root dir is loaded (defaults to 1)
redirect the info page to this URL (defaults to '')
whether to display names from allowed dir (defaults to 1)
the filename containing x-icon data to return when browser requests favicon.ico (defaults to '')
only allow connections from IPs specified in the given file, which contains subnet data in the format: (defaults to '')
don't allow connections from IPs specified in the given file, which contains IP range data in the format: xxx:xxx:ip1-ip2 (defaults to '')
ignore the ip GET parameter from machines which aren't on local network IPs (0 = never, 1 = always, 2 = ignore if NAT checking is not enabled) (defaults to 2)
write tracker logs to this file, use '-' for stdout (defaults to '-')
use with allowed_dir; adds a /file?hash=hash URL that allows users to download the torrent file (defaults to 0)
keep dead torrents after they expire (so they still show up on your /scrape and web page) (defaults to 0)
scrape access allowed (can be none, specific or full) (defaults to full)
the code to require from clients to indicate that they are dedicated seeders. This allows the tracker to monitor dedicated seed(s) and flag torrents as seeded. (defaults to '')
