After Ross quit active development in May 1993, Fred van Kempen began to work on a new implementation, rewriting major parts of the code. This ongoing effort is known as Net-2. A first public release, Net-2d, was made in Summer 1992 (as part of the 0.99.10 kernel), and has since been maintained and expanded by several people, most notably Alan Cox, as Net-2Debugged. After heavy debugging and numerous improvements to the code, he changed its name to Net-3 after 1.0 was released. This is the version of the networking code currently included in the official kernel releases.
Net-3 offers device drivers for a wide variety of Ethernet boards, as well as SLIP (for sending network traffic over serial lines), and PLIP (for parallel lines). With Net-3, has a TCP/IP implementation that behaves very well in a local area network environment, showing uptimes that beat some of the commercial PC . Development currently moves toward the necessary stability to reliably run it on Internet hosts.
Beside these facilities, there are several projects going on that will
enhance the versatility of . A driver for PPP (the
point-to-point protocol, another way to send network traffic over
serial lines), is at Beta stage currently, and an AX.25 driver for ham
radio is at Alpha stage. Alan Cox has also implemented a driver for
Novell's IPX protocol, but the effort for a complete networking suite
compatible with Novell's has been put on hold for the moment, because
of Novell's unwillingness to provide the necessary documentation.
Another very promising undertaking is samba, a
NetBIOS server for Un*x, written by Andrew Tridgell.
