changelog

这是关于远程登陆TELNET 的源代码 已经测试过的。

22-Jul-2000:
	Bug fixes for environment processing from Olaf Kirch. Also fixes
	  privacy issue noticed by Steve Bellovin. Also fix a wrong 
	  assert().

21-May-2000:
	Fix bug found by Herbert Xu ([e-mail]) - telnet
	  was sending terminal type "(null)" as part of the terminal type
	  list.

12-Apr-2000:
	IPPROTO_IP is not a macro in Linux, so don't check it with #ifdef.
	Also, add initial experimental login wrapper, but don't make it 
	  part of the default build.

14-Dec-1999:
	netkit-telnet-0.16 is released.

13-Dec-1999:
	Per recommendation of the linux-security-audit list, don't bother
	  (in telnetd) to ask termcap/ncurses if a terminal type is good;
	assume it is. This means telnetd no longer links against termcap.

12-Dec-1999:
	Massive buffer cleanup in telnetd; minor cleanup to telnet.

5-Dec-1999:
	Remove some more bogus #ifdefs in telnet.

29-Oct-1999:
	Fix latent bug in the array classes used in telnet.

14-Sep-1999:
	Merge old fix to keep telnet from hanging up when under heavy load
	  (Olaf Kirch, [e-mail])

19-Aug-1999:
	Patches for compiling with gcc 2.95. (Jeremy Buhler,
	  [e-mail])

18-Aug-1999:
	netkit-telnet-0.14 released.

17-Aug-1999:
	telnetd patch from Chris Evans to reject termcap entries with 
	  '/' in them, as libtermcap will treat them as paths and open
	  them as root, with various interesting consequences...
	  Issue found by Tymm Twillman ([e-mail]).

1-Aug-1999:
	Massive cleanup of telnetd. Changed telnetd to use openpty() from
	  libutil, so we can let libc deal with changes in pty management.

1-Aug-1999:
	Did complete y2k and y2038 audit. 

31-Jul-1999:
	Redid makefiles/config stuff for new confgen version.

15-Jul-1999:
	Set the process title (visible with ps) to show the remote host name.
	Also filter control characters from the remote host name, just in case.
	Set environment variable REMOTEHOST also.

16-Oct-1997:
	Added OPOST to the terminal stuff a la NCSA telnet fixup

23-Sep-1997:
	Assorted signed/unsigned character fixes and hacking in telnet.
	(Martin Mares, [e-mail])
	Fix various crashes in telnet arising from undefining environment
	variables.
	"telnet h" no longer prints a usage message.

12-Jun-1997:
	netkit-telnet-0.10 released.

08-Jun-1997:
	More adjustments for glibc.
	Include kernel patch to fix hang on long input; thanks to Bill
	  Hawes ([e-mail]).

19-May-1997:
	Fix some nonsense with ayt and signals, since glibc has SIGINFO.

13-May-1997:
	8-bit fix to telnet. (Lukas Wunner, [e-mail])
	Set ut_type correctly in telnetd's logout. (Steve Coile, 
	  [e-mail])

05-Apr-1997:
	Added configure script to generate MCONFIG.
	Better utmp handling in telnetd.

08-Mar-1997: 
	Split from full NetKit package. 
	Generated this change log from NetKit's.

29-Dec-1996
	NetKit-0.09 released.
	Assorted alpha/glibc patches. (Erik Troan, [e-mail])
	Assorted bug fixes from Debian. (Peter Tobias, 
	  [e-mail])
	Telnetd supports -L option for alternate login program. (Peter Tobias)
	Hardened programs against DNS h_length spoofing attacks.
	Use inet_aton() everywhere instead of inet_addr().
	Fixed crash in telnet caused by ^C or ^Z or ^\ under 
	  certain circumstances.
	Rewrote telnet and telnetd man pages.

22-Aug-1996
	NetKit-B-0.08 released.
	(almost) everything now compiles with lots of warnings turned on.
	Massive hacking on telnet.
	telnet honors the -E flag (was broken in .07, .07A)
	telnetd intercepts ENV environment variable.
	Merged libtelnet into telnet and telnetd dirs.
	telnetd now sets idle tty devices to root.root mode 600.

25-Jul-1996
	NetKit-B-0.07A released.
	Fixed a bug in telnet where the escape character was being ignored.
	Fixed a bug in telnetd; now uses the correct names for the last ptys
	  (that is, ptya0-ptyef, not ptyA0-ptyEf.)

23-Jul-1996
	NetKit-B-0.07 released.
	Integrated a collection of patches that had been lurking on the net,
	  including the 256-ptys support for telnetd and passive mode ftp.
	Major security fixes, including to fingerd, lpr, rlogin, rsh, talkd, 
	  and telnetd. Do *not* use the sliplogin from earlier versions of this
	  package, either.
	Much of the code builds without libbsd.a or bsd includes.
	Massive code cleanup. Almost everything compiles clean with gcc
	  -Wall now. rusers and rusersd do not; patches to rpcgen to fix
	  this would be appreciated if anyone feels like it.
	Kerberos support has been removed. It didn't work anyway, and
	  proper Kerberos tools come with Kerberos.
	New maintainer:  David A. Holland, [e-mail]

date not known
	NetKit-B-0.06 released.

date not known
	NetKit-B-0.05 released.
	Fixed writing entries to /var/adm/wtmp by ftpd, rlogind and
	  telnetd. (logwtmp.c) Florian
	  This is only necessary for the GNU last, not for the one 
	  in util-linux...

date not known
	NetKit-B-0.04 released.
	Did some nasty changes to telnet/extern.h. I should really take
	  the current version from NetBSD again and make a clean port of
	  it. (signals).

date not known
	NetKit-B-0.03 released.
	telnetd: changed the default 'etc/issue.net' to not output the
	  hostname and then the domainname (that should be the fqdn, but
	  is wrong!) Changed also the man page issue.net.5
	changed telnetd to get the fqdn and not only use what
	  'gethostname' returns
	telnetd: changed some code back to original form to properly
	  enable binary mode negotiation (outgoing data wasn't binary)
	  Please test this out: do "telnet some_other_not_linux_host" and
	  then do "vi TEST_FILE" and test some strange characters >127
	  like
