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.
