MLdonkey 2.8.2

Description by the Software Developer:
"MLdonkey is a multi-platform multi-networks peer-to-peer client. Originally, MLdonkey was the first open-source client to access the eDonkey network. The protocol was reverse-engineered using an efficient protocol sniffer, Pandora.

MLdonkey runs as a daemon on the computer. It can be controlled using several interfaces: the simplest one is telnet (telnet 127.0.0.1 4000), a more interesting one is a WEB server ( http://127.0.0.1:4080/), and a binary protocol allows access using more elaborate Graphical Interfaces (see the GUIs available on your system at the bottom of the page). MLdonkey comes by default with a GTK interface. All these interfaces can be used locally, or remotely (after disabling security restrictions).
MLdonkey is written in Objective-Caml , a powerful language that runs on most Operating Systems."
