This is the Linux NET-2-HOWTO. This document is a complete rewrite of the earlier NET-FAQ, and of the subsequent NET-2-HOWTO versions 1.0+, for the new NET-2 and NET-3 tcp/ip networking code for Linux kernels 1.0 and above.

1.1 Changes from the previous release.

Additions:
        Added mailing list details for ARCNet support.
        Added IPXBridge software.
        Added Dynamic Address allocation for sliplogin slip server.
        I've based all dip information on dip337j-uri since dip has been
           dropped from the net-tools releases, let me know if I've forgotten
           something.
        diald - demand dialling has been added to experimental code.
        dslip - Matt Dillons slip package.
        Added brief descriptions of the kernel Makefile networking options.
        Added network diagnostic tools section.
        Added sample gated config file.
        Added reference to Stevens "Unix Network Programming" book.
        Added samples of other config files for completeness.
        Added the alpha version of IPXRIPD
        Added reference to the PPP-HOWTO.
        Added other bits and pieces.

Corrections:
        Removed the NIS section and added reference to NIS-HOWTO.
        Updated kernel and libc versions.
        Updated Token Ring driver information.
        Updated ARCNet driver information.
        Updated dip ownership information - thanks Paul Lucassen
        Ammended location details of NetKit package
        Ammended version of sliplogin package.
        Updated PPP information to 2.1.2b

1.2 A brief development history of Linux Networking.

Ross Biro <biro@yggdrasil.com> wrote the original kernel based networking code for Linux. He used ethernet drivers written by Donald Becker <becker@cesdis1.gsfc.nasa.gov>, a slip driver written by Laurence Culhane <loz@holmes.demon.co.uk>, and a D-Link driver by Bj0rn Ekwall <bj0rn@blox.se>.

The further development of the Linux networking code was later taken up by Fred van Kempen <waltje@hacktic.nl>, who took Ross's code and produced the NET-2 release of network code. NET-2 went through a number of revisions until release NET-2d, when Alan Cox <iialan@iifeak.swan.ac.uk> took Fred's NET-2d code and set about debugging the code with the aim of producing a stable and working release of code for incorporation into the standard kernel releases. This code was called NET-2D(ebugged), and has been incorporated into the standard kernel releases since some time before Linux vers 1.0 was released.

PPP support was added by Michael Callahan, <callahan@maths.ox.ac.uk> and Al Longyear, <longyear@netcom.com>, originally as patches to the kernel, and in later releases as part of the standard kernel distribution.

With the release of Linux vers 1.0, Linus made a decision to continue supporting Alan's code as the `standard' network kernel code.

The latest revision of the code, NET-3, appears in kernel releases 1.1.5 and later, and is essentially the same code, but with many fixes, corrections and enhancements.

Alan has added such features as IPX and AX.25 modules. Florian La Roche, <flla@stud.uni-sb.de> has produced an updated distribution of network applications.

Many other people have made contributions by way of bug fixes, ports of applications and by writing device drivers.
