	* sys_term.c: Remove last fragments of PARENT_DOES_UTMP, and
 	remove dependence on utmp.h and utmpx.h

	* telnetd.c: Remove support for -u option as that type of utmp

	version of M_IOCTL handling for systems where termio and termios
	can't be compiled together.
	* termios-tn.c (readstream_termios): new file, provides isolated
	version of M_IOCTL handling for systems where termio and termios
	can't be compiled together.
	* telnetd.c (readstream): use readstream_termios and
	readstream_termio to handle getmsg with M_IOCTL.

Wed Mar 27 00:27:32 1996  Tom Yu  <tlyu@dragons-lair.MIT.EDU>

	* telnetd.c: remove inclusion of netdb.h; it's already in defs.h,
		and #$%&* ultrix doesn't protect it from multiple
		inclusions.

Sat Mar 23 01:33:09 1996  Sam Hartman  <hartmans@tertius.mit.edu>

	* sys_term.c: Remove utmpx stuff so libpty can do it.
	(start_login): Remove utmpx handling here as well.
	(rmut): expunged; libpty should deal.

	* configure.in : Do not use streamspty on SGIs; it really doesn't
 	work, even though all the interfaces are prsent.

	* telnetd.c: Move prototype for doit to be global instead of
        streams-specific.

	Tue Mar 19 18:43:46 1996  Ken Raeburn  <raeburn@cygnus.com>

Mon Mar 18 20:29:05 1996  Theodore Y. Ts'o  <tytso@dcl>

	* Makefile.in: Added flags which turn on the encryption option.

	* telnetd.c (getterminaltype): If the authentication option which
		was negotiated requires that encryption be turned on, then
		enforce this here.

Sun Mar  3 14:43:04 1996  Mark W. Eichin  <eichin@cygnus.com>

	* configure.in: if we don't have termcap, check for curses lib.

Wed Feb 28 21:07:42 1996  Mark Eichin  <eichin@cygnus.com>

	* telnetd.c (telnet): rename HE to HEstr to avoid conflict with

Mon Feb 26 03:33:48 1996  Sam Hartman  <hartmans@tertius.mit.edu>

	* configure.in: Call USE_ANAME

Sun Feb 25 20:26:00 1996  Sam Hartman  <hartmans@tertius.mit.edu>

	* telnetd.c: Use MAXDNAME not MAXHOSTNAMELEN; MAXHOSTNAMELEN is
        only for gethostname() and sethostname() and has nothing to do
        with domains.

	for exceptions that should not be passed to login.
	(suboption): don't do anything to propagated environment variables
	if they fail the exception test above.

Mon Oct  9 23:01:36 1995  Sam Hartman  <hartmans@tertius.mit.edu>

	* telnetd.c (getterminaltype): If ENCRYPTION defined, send do
        encryption, *not* just will encrypt. if you don't do this, then you won't encrypt the input to the server; your password prompt is encrypted, but your password isn't.

Tue Aug  8 11:26:54 1995  Sam Hartman  <hartmans@pao.mit.edu>

	* sys_term.c: Fail if the slave side dies.
	(dup_tty): Renamed from login_tty because OSF already has that function and it isn't compatible.

	(getptyslave): Fix argument to fatalperror by including com_err.h instead of casting.

Tue Aug 8 17:25:22 EDT 1995	Paul Park	(pjpark@mit.edu)
	* sys_term.c - Cast argument to fatalperror().

	Close syncpipe[1] before we read from it.

Mon Aug 7 14:44:21 EDT 1995	Paul Park	(pjpark@mit.edu)
	* configure.in, sys_term.c - Use utmpx.h if present, then check for
		utmp.h.  Add logic to handle ut_tv from utmpx.h.


Mon Aug 7 13:08:39 EDT 1995	Paul Park	(pjpark@mit.edu)
	* configure.in - Add check for utmp.h.  Make check for utmpx.h define
		additional symbol to work with libpty.h.
	* sys_term.c - Fix syntax error and reinstate #ifdef LINEMODE deleted
		by last checkin.

Fri Aug  4 20:22:28 1995  Sam Hartman  <hartmans@tertius.mit.edu>

	* sys_term.c (getptyslave): Select terminal settings more likely
        to work.
	(cleanup): Pass pid to cleanup so it can killpg if necessary.

Tue Aug  1 11:28:55 1995  Sam Hartman  <hartmans@tertius.mit.edu>

	* telnetd.c (doit): Use pty_getpty.

	* Makefile.in (LOCAL_LIBRARIES): Add -lpty

	* sys_term.c (startslave): Use pty_update_utmp.  Export slave's
        pid so it's global for pty_cleanup.  Use pipe to synchronize so
        that slave is opened before parent writes.
	(cleanopen): removed in favor of pty_open_slave
	(login_tty): Don't set controlling terminal; libpty does this.  Just dup2 the terminals.
	(getpty): removed.

	(getptyslave): Use libpty.

	* telnetd-ktd.c: Use libpty.

Tue Jul 11 11:32:56 1995  Sam Hartman  <hartmans@tertius.mit.edu>

Sat Jul 29 04:40:04 1995  Tom Yu  <tlyu@dragons-lair.MIT.EDU>


	* telnetd-ktd.c (doit): Remove special casing of Convex PTY
        handling here.  There isn't enough code here for me to understand
        what to do on a Convex system, so if it breaks, it should be
        special cased in a more-appropriate manner.


	* configure.in: Don't link with -lkadm.

Fri Jul 7 15:51:03 EDT 1995	Paul Park	(pjpark@mit.edu)
	* Makefile.in - Remove explicit library handling.
	* configure.in - Add USE_{KRB4,KADM}_LIBRARY and KRB5_LIBRARIES.

Tue Jun 20 14:25:01 1995  Tom Yu  (tlyu@dragons-lair)

	* defs.h: NO_STRING_H -> HAVE_STRING_H

Thu Jun 15 17:43:21 EDT 1995	Paul Park	(pjpark@mit.edu)
	* Makefile.in - Change explicit library names to -l<lib> form, and
		change target link line to use $(LD) and associated flags.
		Also, remove DBMLIB, it was not used. Also, for K4, use
		KRB4_LIB and KRB4_CRYPTO_LIB, these were
                split out.
	* configure.in - Remove dbm library checks, these are no longer needed
		with the Berkeley database code.  Also, add shared library
		usage check.


Thu Jun 15 16:18:39 1995  Sam Hartman  <hartmans@tardis.MIT.EDU>

	* sys_term.c (getpty): On AIX, open /dev/ptc for master and use
        ttyname() to get slave side; much simpler and doesn't get used
        ptys.

	(cleanopen): Revoke on AIX as well.  This may cause problems on early 3.2 versions, but not revoking causes disconnected sessions to be partially connected to new telnets.  The complete fix will be to make sure telnetd cleans up when it dies.




Fri Jun  9 18:29:56 1995    <tytso@rsx-11.mit.edu>

	* configure.in: Remove standardized set of autoconf macros, which

	* configure.in: use WITH_KRB4 as-is.

Wed Apr 25 22:53:20 1995  Chris Provenzano  (proven@mit.edu)

        * configure.in, sys_term.c, telnetd.c : Have configure check for

Sat Apr 22 00:52:01 1995  Theodore Y. Ts'o  (tytso@dcl)

	* telnetd.c (main): Don't use krb5_override_default_realm, as it

	From Ian Taylor <ian@cygnus.com>.
	* telnetd.c (valid_opts): Add 'L'.  If KRB5, add -R and -t.
	(main): Handle -L.  If KRB5, handle -R and -t.
	* sys_term.c (login_program): New global variable.

Wed Mar  1 16:25:58 1995  Theodore Y. Ts'o  <tytso@dcl>

	* configure.in: Remove ISODE_INCLUDE and ISODE_DEFS, replace check
		for -lsocket and -lnsl with WITH_NETLIB check.

	SETPGRP_TWOARG check.

	(telnetd): use $(K4LIB). (from epeisach)

Mon Nov  7 22:16:51 1994  Theodore Y. Ts'o  (tytso@dcl)

	* configure.in: 
	  sys_term.c: Only include <sys/tty.h> if HAVE_SYS_TTY_H is
	  	  defined by configure.
