XBT Tracker

Overview

XBT Tracker is a BitTorrent tracker written in C++. It's designed to offer high performance while consuming little resources (CPU and RAM). It's a pure tracker, so it doesn't offer a frontend. You can use any (PHP) frontend you want.

XBT Tracker listens on port 2710. The announce URL is http://...:2710/announce. The debug URL is http://...:2710/debug. The scrape URL is http://...:2710/scrape. The statistics URL is http://...:2710/statistics. An experimental UDP tracker extension is also supported via announce URL udp://...:2710.

MySQL

The tracker stores stats in a MySQL database/table. Version >= 5 is required. Create a database (xbt) and a user (xbt) with password for the tracker and use these in the next step. Create the tables defined in xbt_tracker.sql.

Installing under Windows

Download XBT Tracker from http://sourceforge.net/project/showfiles.php?group_id=94951&package_id=113737.
Run the executable.
Update xbt_tracker.conf with the database, host, user and pass of your MySQL setup.

There are two ways to run the tracker under Windows (NT, 2000, XP and 2003). The first way is to run the tracker manually, like every other application. The second way is to run the tracker as service. The advantage of this way is that it also runs when no user is logged in.

Open a command window (Start - Run - cmd).
Run net start "XBT Tracker"

Starting under Windows

Just start the executable. An empty DOS window should appear.

Installing under Linux

The following commands can be used to install the dependencies on Debian. The g++ version should be at least 3.4.

apt-get install cmake g++ libboost-date-time-dev libboost-dev libboost-filesystem-dev libboost-program-options-dev libboost-regex-dev libboost-serialization-dev libmysqlclient15-dev make subversion zlib1g-dev

The following commands can be used to install some of the dependencies on CentOS, Fedora Core and Red Hat. The g++ version should be at least 3.4.

yum install boost-devel gcc-c++ mysql-devel subversion

Enter the following commands in a terminal. Be patient while g++ is running, it'll take a few minutes.

svn co http://xbt.googlecode.com/svn/trunk/xbt/misc xbt/misc
svn co http://xbt.googlecode.com/svn/trunk/xbt/Tracker xbt/Tracker
cd xbt/Tracker
./make.sh
cp xbt_tracker.conf.default xbt_tracker.conf

Starting under Linux

Enter the following commands in a terminal.

./xbt_tracker

Stopping under Linux

Enter the following commands in a terminal.

killall xbt_tracker

Configuration

The tracker reads it's configuration from the file xbt_tracker.conf and the SQL table xbt_config. There is no need to insert default values into this table.

anonymous_connect		1
anonymous_announce		1
anonymous_scrape		1
auto_register		1
clean_up_interval		60
daemon		1
debug		0
full_scrape		0

table_files_users		xbt_files_users
table_scrape_log		xbt_scrape_log
table_users		xbt_users
write_db_interval		15

Auto Register

If auto_register is on, the tracker will track any torrent. If it's off, the tracker will only track torrents (identified by info_hash) that are in the xbt_files table.

insert into xbt_files (info_hash, mtime, ctime) values ('<info_hash>', unix_timestamp(), unix_timestamp()); // insert
update xbt_files set flags = 1 where info_hash = '<info_hash>'; // delete

Anonymous Announce

If anonymous_announce is on, the tracker will serve any user. If it's off, the tracker will only serve users (identified by torrent_pass) that are in the xbt_users table.

The torrent_pass field in xbt_users contains the 32 char torrent_pass. The announce URL contains the same torrent_pass: /<torrent_pass>/announce
