|

This release represents what is on the 4.4BSD-Lite2 release, which
|
||||
should be the final BSD release. I will continue to support of
|
||||
telnet, The code (without encryption) is available via anonymous ftp
|
||||
from ftp.cray.com, in src/telnet/telnet.YY.MM.DD.NE.tar.Z, where
|
||||
YY.MM.DD is replaced with the year, month and day of the release.
|
||||
If you can't find it at one of these places, at some point in the
|
||||
near future information about the latest releases should be available
|
||||
from ftp.borman.com.
|
||||
|
||||
In addition, the version with the encryption code is available via
|
||||
ftp from net-dist.mit.edu, in the directory /pub/telnet. There
|
||||
is a README file there that gives further information on how
|
||||
to get the distribution.
|
||||
|
||||
Questions, comments, bug reports and bug fixes can be sent to
|
||||
one of these addresses:
|
||||
dab@borman.com
|
||||
dab@cray.com
|
||||
dab@bsdi.com
|
||||
|
||||
This release is mainly bug fixes and code cleanup.
|
||||
|
||||
Replace all calls to bcopy()/bzero() with calls to
|
||||
memmove()/memset() and all calls to index()/rindex()
|
||||
with calls to strchr()/strrchr().
|
||||
|
||||
Add some missing diagnostics for option tracing
|
||||
to telnetd.
|
||||
|
||||
Add support for BSDI 2.0 and Solaris 2.4.
|
||||
|
||||
Add support for UNICOS 8.0
|
||||
|
||||
Get rid of expanded tabs and trailing white spaces.
|
||||
|
||||
From Paul Vixie:
|
||||
Fix for telnet going into an endless spin
|
||||
when the session dies abnormally.
|
||||
|
||||
From Jef Poskanzer:
|
||||
Changes to allow telnet to compile
|
||||
under SunOS 3.5.
|
||||
|
||||
From Philip Guenther:
|
||||
makeutx() doesn't expand utmpx,
|
||||
use pututxline() instead.
|
||||
|
||||
From Chris Torek:
|
||||
Add a sleep(1) before execing login
|
||||
to avoid race condition that can eat
|
||||
up the login prompt.
|
||||
Use terminal speed directly if it is
|
||||
not an encoded value.
|
||||
|
||||
From Steve Parker:
|
||||
Fix to realloc() call. Fix for execing
|
||||
login on solaris with no user name.

This is a list of some of the changes since the last tar release
|
||||
of telnet/telnetd. There are probably other changes that aren't
|
||||
listed here, but this should hit a lot of the main ones.
|
||||
|
||||
General:
|
||||
Changed #define for AUTHENTICATE to AUTHENTICATION
|
||||
Changed #define for ENCRYPT to ENCRYPTION
|
||||
Changed #define for DES_ENCRYPT to DES_ENCRYPTION
|
||||
|
||||
Added support for SPX authentication: -DSPX
|
||||
|
||||
Added support for Kerberos Version 5 authentication: -DKRB5
|
||||
|
||||
Added support for ANSI C function prototypes
|
||||
|
||||
Added support for the NEW-ENVIRON option (RFC-1572)
|
||||
including support for USERVAR.
|
||||
|
||||
Made support for the old Environment Option (RFC-1408)
|
||||
conditional on -DOLD_ENVIRON
|
||||
|
||||
Added #define ENV_HACK - support for RFC 1571
|
||||
|
||||
The encryption code is removed from the public distributions.
|
||||
Domestic 4.4 BSD distributions contain the encryption code.
|
||||
|
||||
ENV_HACK: Code to deal with systems that only implement
|
||||
the old ENVIRON option, and have reversed definitions
|
||||
of ENV_VAR and ENV_VAL. Also fixes ENV processing in
|
||||
client to handle things besides just the default set...
|
||||
|
||||
NO_BSD_SETJMP: UNICOS configuration for
|
||||
UNICOS 6.1/6.0/5.1/5.0 systems.
|
||||
|
||||
STREAMSPTY: Use /dev/ptmx to get a clean pty. This
|
||||
is for SVr4 derivatives (Like Solaris)
|
||||
|
||||
UTMPX: For systems that have /etc/utmpx. This is for
|
||||
SVr4 derivatives (Like Solaris)
|
||||
|
||||
Definitions for BSDI 1.0
|
||||
|
||||
Definitions for 4.3 Reno and 4.4 BSD.

||||
|
||||
Definitions for UNICOS 8.0 and UNICOS 7.C

||||
Definitions for Solaris 2.0
|
||||
|
||||
Definitions for HP-UX 8.0
|
||||
|
||||
Latest Copyright notices from Berkeley.

||||
|
||||
FLOW-CONTROL: support for RFC-XXXx
|
||||
|
||||
|
||||
Client Specific:
|
||||
|
||||
Fix the "send" command to not send garbage...
|
||||
|
||||
Fix status message for "skiprc"
|
||||
|
||||
Make sure to send NAWS after telnet has been suspended
|
||||
or an external command has been run, if the window size
|
||||
has changed.
|
||||
|
||||
sysV88 support.
|
||||
|
||||
Server Specific:
|
||||
|
||||
Support flowcontrol option in non-linemode servers.
|
||||
|
||||
-k Server supports Kludge Linemode, but will default to
|
||||
either single character mode or real Linemode support.
|
||||
The user will have to explicitly ask to switch into
|
||||
kludge linemode. ("stty extproc", or escape back to
|
||||
to telnet and say "mode line".)
|
||||
|
||||
-u Specify the length of the hostname field in the utmp
|
||||
file. Hostname longer than this length will be put
|
||||
into the utmp file in dotted decimal notation, rather
|
||||
than putting in a truncated hostname.
|
||||
|
||||
-U Registered hosts only. If a reverse hostname lookup
|
||||
fails, the connection will be refused.
|
||||
|
||||
-f/-F
|
||||
Allows forwarding of credentials for KRB5.
