- 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.
