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.
January 19, 1994
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.
