misterion / opentracker Goto Github PK

This is opentracker. An open bittorrent tracker.

It's a bit modified to collect download statistics from gamenet application. It uses redis backend to store data - `lastUpdated` set with last updated users. And one hset per each user. Hset fields are concatenated string separated by dot - torrent hash, connection id, event name. You may find two special fields - status and time. They used to aggregate data per time. Also we use hset `infohash` to calculate hash => aggregate id information.

You need libowfat (http://www.fefe.de/libowfat/), hiredis client (https://github.com/redis/hiredis) and OpenSSL crypto library (https://www.openssl.org/). If you are going to store dl/ul statistics locally, you need Redis (http://redis.io/) daemon running as well.

Steps to go:

cvs -d :pserver:[email protected]:/cvs -z9 co libowfat
cd libowfat
make
cd ..
cvs -d:pserver:[email protected]:/home/cvsroot co opentracker
cd opentracker
make
./opentracker

This tracker is open in a sense that everyone announcing a torrent is welcome to do so and will be informed about anyone else announcing the same torrent. Unless
-DWANT_IP_FROM_QUERY_STRING is enabled (which is meant for debugging purposes only), only source IPs are accepted. The tracker implements a minimal set of
essential features only but was able respond to far more than 10000 requests per second on a Sun Fire 2200 M2 (thats where we found no more clients able to fire
more of our testsuite.sh script).

Some tweaks you may want to try under FreeBSD:

sysctl kern.ipc.somaxconn=1024
sysctl kern.ipc.nmbclusters=32768
sysctl net.inet.tcp.msl=10000
sysctl kern.maxfiles=10240
