giFT-FastTrack is an Open Source implementation of the FastTrack P2P protocol used by KaZaA, iMesh and Grokster.
We use giFT as a framework and have developed giFT-FastTrack as a plugin for it.
giFT is a portable filesharing daemon which can be used with different front ends and can connect to multiple networks via plugins.
The latest version is 0.8.9 which solves some bugs in 0.8.8 leading to random crashes.
Important notice: A remote denial of service attack has been discovered in version 0.8.6 and prior. Even though no code execution is possible it is recommended that you update to 0.8.9 as soon as possible. Thanks to Alan F for bringing this to our attention.
You can download the most recent sources from the download page on berlios.
We also have debian packages for the latest release.
For Windows users we have a binary installer giFT-FastTrack-0.8.9.exe (works with KCeasy and giFTwin32)
For Mac OS there is poisoned, which includes giFT and giFT-FastTrack.
