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.
