+			LINUX NET DISTRIBUTION
+
+			    Version 0.03
+
+	    Fred N. van Kempen <waltje@uwalt.nl.mugnet.org>
+
+		Ross Biro <bir7@leland.stanford.edu>
+
+		  Rick Sladkey <jrs@world.std.com>
+
+
+The NET distribution for LINUX is a complete set of executables,
+setup files, documentation and all the sources needed to rebuild
+the package.  It is intended as the `official' NET package for
+the LINUX operating system, mostly to get rid of the current
+situation of total chaos in NETland...
+
+The first distribution has been done by Ross Biro, who wrote the
+TCP/IP stuff in the LINUX kernel to start with.  As usual, the
+Berkeley BSD UNIX software was taken as a base for this distri-
+bution.  Several `foreign' programs are included as well.
+
+To make porting easy, a library has been built which contains the
+modules from BSD UNIX that were missing in the LINUX library. They
+are declared in the header files that go with it.  These files
+must be copied to the /usr/net/include/bsd directory and a symbolic
+link must be created from /usr/include/bsd.
+
+This is a compliation of some net sources, mostly from bsd-net2.  I
+have made an effort to get the programs to compile with few or no
+changes except for a new Makefile.  This resulted in a bsd include
+directory and a bsd library.  Take a look at them to see what types of
+things are required to get BSD sources to compile correctly without
+changes.  Some of the tricks are pretty ugly.  Please don't laugh...
+
+Everything should compile straight with the libc-4.2 libraries.  Just
+type "make" in this directory.  You may have to do some surgery on
+libbsd/libbsd.a to get things to compile with libc-4.1.
+
+Notes
+=====
+
+bsd: The directory "bsd" contains include files that, for the most
+part, just overload include files of the same name from /usr/include.
+It provides some BSD things like "union wait" and others.
+
+libbsd: The libbsd.a archive is a small library of some functions that
+are not in our libc as well as some emulation support functions
+referenced in the bsd header files.  Notably, it includes a
+half-decent transparent sgtty emulation package.
+
+inetd: Works.  Only pathname changes.
+
+ftp: Works.  No changes.
+
+ftpd: I find that ls with ftpd doesn't work very often.  It reports
+"Transport endpoint already connected" 9 times out of 10.  I think
+this is a bug in the kernel which will be fixed in a subsequent
+release.  There was a memory allocation bug in the original source,
+look for "#ifdef linux".  Also, the shadow password stuff is not
+compiled in as I haven't had a chance to mess with that.
+
+telnet: Works but see the man page for info about the .telnetrc file
+and other new options.  This is a really nice telnet with rlogin
+emulation and lots of other stuff not present in older telnets.  The
+original Linux port of telnet/telnetd was done by Pete Chown.
+
+telnetd: Several people have reported that the 0.1 telnetd sometimes
+disconnected before getting to the login prompt.  The 0.2 version
+omits the vhangup stuff which might have been causing the problem.
+Also fixed is the problem with /etc/wtmp not being updated correctly
+on logout.  It was trying to use /var/adm/wtmp.
+
+finger: Works.  One minor change for POSIX timezone handling.
+
+fingerd: Works, no changes.
+
+ping: Works, no changes.  Must be suid to root.
+
+named: Works.  A few changes for pathnames and net device
+configuration stuff.
+
+nslookup: Works, but it's fussier than older nslookups about named
+being setup correctly.  Note the -I option is needed for flex -- that
+was a tough one to find.  No changes.
+
+named-xfer: Not tested.
+
+rcp: Works.  Must be suid to root.
+
+rsh: Works.  Must be suid to root.
+
+rshd: Works.
+
+rlogin: Works OK but needs more testing.  This one depends pretty heavily
+on the sgtty emulation in libbsd which is not complete yet.  There is
+an odd timing bug with select and termio settings.  Look for "sleep(1)"
+to see what I mean.  Must be suid to root.
+
+rlogind: Works with the URGENT stuff commented out.  There was a nasty
+bug with shared libraries because environ was redefined.
+
+talk: Works.  This is the new byte-order independent talk, not the old
+talk that, e.g., native SunOS uses.  The old one wouldn't work with
+them anyway.  Not the fault of Linux.  Includes a one line patch for a
+bug in our curses and another for a bug in the original source dealing
+with select.
+
+ntalkd: Works.  No changes.
+
+tftp: Works.  No changes.
+
+tftpd: Works.  No changes.

+HJ,
+
+This is the source of the current "libbsd.a" as I have it
+next to the libc 4.3.2.  You can safely ignore the blahblah
+in the other README- throw it away after you added this stuff
+to the rest of libc...
+
+I think the best way to add this to the standard set of C
+libraries is to keep it in the form of a single non-sharable
+library (/usr/lib/libbsd.a) that only gets linked if the user
+asks for it by typing "-lbsd".  I don't know if this is pos-
+sible, but I don't think it should be added to the "shared"
+image, because it might cause other problems in that case...
+
+Fred.
