OpenNAP

OpenNAP is a piece of free software that replicates the functionality of the once-popular Napster peer-to-peer filesharing server. OpenNAP uses a free Napster-like protocol with extended functionality, is released under the GNU General Public License, and runs under Unix-like operating systems, such as Linux, Mac OS X, and under Windows NT and Windows 2000.

The main website for the OpenNAP project is here (Note: This site has not been updated since November 15, 2001.)

OpenNAP clients:

• Lopster (GPL, for Unix-like systems, Gtk)
• XNap for Mac OS X and various other systems
• Teknap
• Napster for BeOS versions 1.06 and above.

SlavaNap is an alternative OpenNap server.

There is also a newer version called opennap-ng.
