Februrary 22, 1991:
|
||||||
|
|
||||||
|
Features:
|
||||||
|
|
||||||
|
This version of telnet/telnetd has support for both
|
||||||
|
the AUTHENTICATION and ENCRYPTION options. The
|
||||||
|
AUTHENTICATION option is fairly well defined, and
|
||||||
|
an option number has been assigned to it. The
|
||||||
|
ENCRYPTION option is still in a state of flux; an
|
||||||
|
option number has NOT been assigned to it yet.
|
||||||
|
The code is provided in this release for experimental
|
||||||
|
and testing purposes.
|
||||||
|
|
||||||
|
The telnet "send" command can now be used to send
|
||||||
|
do/dont/will/wont commands, with any telnet option
|
||||||
|
name. The rules for when do/dont/will/wont are sent
|
||||||
|
are still followed, so just because the user requests
|
||||||
|
that one of these be sent doesn't mean that it will
|
||||||
|
be sent...
|
||||||
|
|
||||||
|
The telnet "getstatus" command no longer requires
|
||||||
|
that option printing be enabled to see the response
|
||||||
|
to the "DO STATUS" command.
|
||||||
|
|
||||||
|
A -n flag has been added to telnetd to disable
|
||||||
|
keepalives.
|
||||||
|
|
||||||
|
A new telnet command, "auth" has been added (if
|
||||||
|
AUTHENTICATE is defined). It has four sub-commands,
|
||||||
|
"status", "debug", "disable", "enable" and "help".
|
||||||
|
|
||||||
|
A new telnet command, "encrypt" has been added (if
|
||||||
|
ENCRYPT is defined). It has many sub-commands:
|
||||||
|
"enable", "type", "start", "stop", "input",
|
||||||
|
"-input", "output", "-output", "status", "auto",
|
||||||
|
"verbose", "debug", and "help".
|
||||||
|
|
||||||
|
An "rlogin" interface has been added. If the program
|
||||||
|
is named "rlogin", or the "-r" flag is given, then
|
||||||
|
an rlogin type of interface will be used.
|
||||||
|
~. Terminates the session
|
||||||
|
~<susp> Suspend the session
|
||||||
|
~^] Escape to telnet command mode
|
||||||
|
~~ Pass through the ~.
|
||||||
|
BUG: If you type the rlogin escape character
|
||||||
|
in the middle of a line while in rlogin
|
||||||
|
mode, you cannot erase it or any characters
|
||||||
|
before it. Hopefully this can be fixed
|
||||||
|
in a future release...
|
||||||
|
|
||||||
|
General changes:
|
||||||
|
|
||||||
|
A "libtelnet.a" has now been created. This libraray
|
||||||
|
contains code that is common to both telnet and
|
||||||
|
telnetd. This is also where library routines that
|
||||||
|
are needed, but are not in the standard C library,
|
||||||
|
are placed.
|
||||||
|
|
||||||
|
The makefiles have been re-done. All of the site
|
||||||
|
specific configuration information has now been put
|
||||||
|
into a single "Config.generic" file, in the top level
|
||||||
|
directory. Changing this one file will take care of
|
||||||
|
all three subdirectories. Also, to add a new/local
|
||||||
|
definition, a "Config.local" file may be created
|
||||||
|
at the top level; if that file exists, the subdirectories
|
||||||
|
will use that file instead of "Config.generic".
|
||||||
|
|
||||||
|
Many 1-2 line functions in commands.c have been
|
||||||
|
removed, and just inserted in-line, or replaced
|
||||||
|
with a macro.
|
||||||
|
|
||||||
|
Bug Fixes:
|
||||||
|
|
||||||
|
The non-termio code in both telnet and telnetd was
|
||||||
|
setting/clearing CTLECH in the sg_flags word. This
|
||||||
|
was incorrect, and has been changed to set/clear the
|
||||||
|
LCTLECH bit in the local mode word.
|
||||||
|
|
||||||
|
The SRCRT #define has been removed. If IP_OPTIONS
|
||||||
|
and IPPROTO_IP are defined on the system, then the
|
||||||
|
source route code is automatically enabled.
|
||||||
|
|
||||||
|
The NO_GETTYTAB #define has been removed; there
|
||||||
|
is a compatability routine that can be built into
|
||||||
|
libtelnet to achive the same results.
|
||||||
|
|
||||||
|
The server, telnetd, has been switched to use getopt()
|
||||||
|
for parsing the argument list.
|
||||||
|
|
||||||
|
The code for getting the input/output speeds via
|
||||||
|
cfgetispeed()/cfgetospeed() was still not quite
|
||||||
|
right in telnet. Posix says if the ispeed is 0,
|
||||||
|
then it is really equal to the ospeed.
|
||||||
|
|
||||||
|
The suboption processing code in telnet now has
|
||||||
|
explicit checks to make sure that we received
|
||||||
|
the entire suboption (telnetd was already doing this).
|
||||||
|
|
||||||
|
The telnet code for processing the terminal type
|
||||||
|
could cause a core dump if an existing connection
|
||||||
|
was closed, and a new connection opened without
|
||||||
|
exiting telnet.
|
||||||
|
|
||||||
|
Telnetd was doing a TCSADRAIN when setting the new
|
||||||
|
terminal settings; This is not good, because it means
|
||||||
|
that the tcsetattr() will hang waiting for output to
|
||||||
|
drain, and telnetd is the only one that will drain
|
||||||
|
the output... The fix is to use TCSANOW which does
|
||||||
|
not wait.
|
||||||
|
|
||||||
|
Telnetd was improperly setting/clearing the ISTRIP
|
||||||
|
flag in the c_lflag field, it should be using the
|
||||||
|
c_iflag field.
|
||||||
|
|
||||||
|
When the child process of telnetd was opening the
|
||||||
|
slave side of the pty, it was re-setting the EXTPROC
|
||||||
|
bit too early, and some of the other initialization
|
||||||
|
code was wiping it out. This would cause telnetd
|
||||||
|
to go out of linemode and into single character mode.
|
||||||
|
|
||||||
|
One instance of leaving linemode in telnetd forgot
|
||||||
|
to send a WILL ECHO to the client, the net result
|
||||||
|
would be that the user would see double character
|
||||||
|
echo.
|
||||||
|
|
||||||
|
If the MODE was being changed several times very
|
||||||
|
quickly, telnetd could get out of sync with the
|
||||||
|
state changes and the returning acks; and wind up
|
||||||
|
being left in the wrong state.
|
||||||
|
|
||||||
|
September 14, 1990:
|
||||||
|
|
||||||
|
Switch the client to use getopt() for parsing the
|
||||||
|
argument list. The 4.3Reno getopt.c is included for
|
||||||
|
systems that don't have getopt().
|
||||||
|
|
||||||
|
Use the posix _POSIX_VDISABLE value for what value
|
||||||
|
to use when disabling special characters. If this
|
||||||
|
is undefined, it defaults to 0x3ff.
|
||||||
|
|
||||||
|
For non-termio systems, TIOCSETP was being used to
|
||||||
|
change the state of the terminal. This causes the
|
||||||
|
input queue to be flushed, which we don't want. This
|
||||||
|
is now changed to TIOCSETN.
|
||||||
|
|
||||||
|
Take out the "#ifdef notdef" around the code in the
|
||||||
|
server that generates a "sync" when the pty oputput
|
||||||
|
is flushed. The potential problem is that some older
|
||||||
|
telnet clients may go into an infinate loop when they
|
||||||
|
receive a "sync", if so, the server can be compiled
|
||||||
|
with "NO_URGENT" defined.
|
||||||
|
|
||||||
|
Fix the client where it was setting/clearing the OPOST
|
||||||
|
bit in the c_lflag field, not the c_oflag field.
|
||||||
|
|
||||||
|
Fix the client where it was setting/clearing the ISTRIP
|
||||||
|
bit in the c_lflag field, not the c_iflag field. (On
|
||||||
|
4.3Reno, this is the ECHOPRT bit in the c_lflag field.)
|
||||||
|
The client also had its interpretation of WILL BINARY
|
||||||
|
and DO BINARY reversed.
|
||||||
|
|
||||||
|
Fix a bug in client that would cause a core dump when
|
||||||
|
attempting to remove the last environment variable.
|
||||||
|
|
||||||
|
In the client, there were a few places were switch()
|
||||||
|
was being passed a character, and if it was a negative
|
||||||
|
value, it could get sign extended, and not match
|
||||||
|
the 8 bit case statements. The fix is to and the
|
||||||
|
switch value with 0xff.
|
||||||
|
|
||||||
|
Add a couple more printoption() calls in the client, I
|
||||||
|
don't think there are any more places were a telnet
|
||||||
|
command can be received and not printed out when
|
||||||
|
"options" is on.
|
||||||
|
|
||||||
|
A new flag has been added to the client, "-a". Currently,
|
||||||
|
this just causes the USER name to be sent across, in
|
||||||
|
the future this may be used to signify that automatic
|
||||||
|
authentication is requested.
|
||||||
|
|
||||||
|
The USER variable is now only sent by the client if
|
||||||
|
the "-a" or "-l user" options are explicity used, or
|
||||||
|
if the user explicitly asks for the "USER" environment
|
||||||
|
variable to be exported. In the server, if it receives
|
||||||
|
the "USER" environment variable, it won't print out the
|
||||||
|
banner message, so that only "Password:" will be printed.
|
||||||
|
This makes the symantics more like rlogin, and should be
|
||||||
|
more familiar to the user. (People are not used to
|
||||||
|
getting a banner message, and then getting just a
|
||||||
|
"Password:" prompt.)
|
||||||
|
|
||||||
|
Re-vamp the code for starting up the child login
|
||||||
|
process. The code was getting ugly, and it was
|
||||||
|
hard to tell what was really going on. What we
|
||||||
|
do now is after the fork(), in the child:
|
||||||
|
1) make sure we have no controlling tty
|
||||||
|
2) open and initialize the tty
|
||||||
|
3) do a setsid()/setpgrp()
|
||||||
|
4) makes the tty our controlling tty.
|
||||||
|
On some systems, #2 makes the tty our controlling
|
||||||
|
tty, and #4 is a no-op. The parent process does
|
||||||
|
a gets rid of any controlling tty after the child
|
||||||
|
is fork()ed.
|
||||||
|
|
||||||
|
Use the strdup() library routine in telnet, instead
|
||||||
|
of the local savestr() routine. If you don't have
|
||||||
|
strdup(), you need to define NO_STRDUP.
|
||||||
|
|
||||||
|
Add support for ^T (SIGINFO/VSTATUS), found in the
|
||||||
|
4.3Reno distribution. This maps to the AYT character.
|
||||||
|
You need a 4-line bugfix in the kernel to get this
|
||||||
|
to work properly:

|
||||||
|
|
||||||
|
The client is now smarter when setting the telnet escape
|
||||||
|
character; it only sets it to one of VEOL and VEOL2 if
|
||||||
|
one of them is undefined, and the other one is not already
|
||||||
|
defined to the telnet escape character.
|
||||||
|
|
||||||
|
Handle TERMIOS systems that have seperate input and output
|
||||||
|
line speed settings imbedded in the flags.
|
||||||
|
|
||||||
|
Many other minor bug fixes.
|
||||||
|
|
||||||
|
June 20, 1990:
|
||||||
|
Re-organize makefiles and source tree. The telnet/Source
|
||||||
|
directory is now gone, and all the source that was in
|
||||||
|
telnet/Source is now just in the telnet directory.
|
||||||
|
|
||||||
|
Seperate makefile for each system are now gone. There
|
||||||
|
are two makefiles, Makefile and Makefile.generic.
|
||||||
|
The "Makefile" has the definitions for the various
|
||||||
|
system, and "Makefile.generic" does all the work.
|
||||||
|
There is a variable called "WHAT" that is used to
|
||||||
|
specify what to make. For example, in the telnet
|
||||||
|
directory, you might say:
|
||||||
|
make 4.4bsd WHAT=clean
|
||||||
|
to clean out the directory.
|
||||||
|
|
||||||
|
Add support for the ENVIRON and XDISPLOC options.
|
||||||
|
In order for the server to work, login has to have
|
||||||
|
the "-p" option to preserve environment variables.
|
||||||
|
|
||||||
|
Add the SOFT_TAB and LIT_ECHO modes in the LINEMODE support.
|
||||||
|
|
||||||
|
Add the "-l user" option to command line and open command
|
||||||
|
(This is passed through the ENVIRON option).
|
||||||
|
|
||||||
|
Add the "-e" command line option, for setting the escape
|
||||||
|
character.
|
||||||
|
|
||||||
|
Add the "-D", diagnostic, option to the server. This allows
|
||||||
|
the server to print out debug information, which is very
|
||||||
|
useful when trying to debug a telnet that doesn't have any
|
||||||
|
debugging ability.
|
||||||
|
|
||||||
|
Turn off the literal next character when not in LINEMODE.
|
||||||
|
|
||||||
|
Don't recognize ^Y locally, just pass it through.
|
||||||
|
|
||||||
|
Make minor modifications for Sun4.0 and Sun4.1
|
||||||
|
|
||||||
|
Add support for both FORW1 and FORW2 characters. The
|
||||||
|
telnet escpape character is set to whichever of the
|
||||||
|
two is not being used. If both are in use, the escape
|
||||||
|
character is not set, so when in linemode the user will
|
||||||
|
have to follow the escape character with a <CR> or <EOF)
|
||||||
|
to get it passed through.
|
||||||
|
|
||||||
|
Commands can now be put in single and double quotes, and
|
||||||
|
a backslash is now an escape character. This is needed
|
||||||
|
for allowing arbitrary strings to be assigned to environment
|
||||||
|
variables.
|
||||||
|
|
||||||
|
Switch telnetd to use macros like telnet for keeping
|
||||||
|
track of the state of all the options.
|
||||||
|
|
||||||
|
Fix telnetd's processing of options so that we always do
|
||||||
|
the right processing of the LINEMODE option, regardless
|
||||||
|
of who initiates the request to turn it on. Also, make
|
||||||
|
sure that if the other side went "WILL ECHO" in response
|
||||||
|
to our "DO ECHO", that we send a "DONT ECHO" to get the
|
||||||
|
option turned back off!
|
||||||
|
|
||||||
|
Fix the TERMIOS setting of the terminal speed to handle both
|
||||||
|
BSD's seperate fields, and the SYSV method of CBAUD bits.
|
||||||
|
|
||||||
|
Change how we deal with the other side refusing to enable
|
||||||
|
an option. The sequence used to be: send DO option; receive
|
||||||
|
WONT option; send DONT option. Now, the sequence is: send
|
||||||
|
DO option; receive WONT option. Both should be valid
|
||||||
|
according to the spec, but there has been at least one
|
||||||
|
client implementation of telnet identified that can get
|
||||||
|
really confused by this. (The exact sequence, from a trace
|
||||||
|
on the server side, is (numbers are number of responses that
|
||||||
|
we expect to get after that line...):
|
||||||
|
|
||||||
|
send WILL ECHO 1 (initial request)
|
||||||
|
send WONT ECHO 2 (server is changing state)
|
||||||
|
recv DO ECHO 1 (first reply, ok. expect DONT ECHO next)
|
||||||
|
send WILL ECHO 2 (server changes state again)
|
||||||
|
recv DONT ECHO 1 (second reply, ok. expect DO ECHO next)
|
||||||
|
recv DONT ECHO 0 (third reply, wrong answer. got DONT!!!)
|
||||||
|
*** send WONT ECHO (send WONT to acknowledge the DONT)
|
||||||
|
send WILL ECHO 1 (ask again to enable option)
|
||||||
|
recv DO ECHO 0
|
||||||
|
|
||||||
|
recv DONT ECHO 0
|
||||||
|
send WONT ECHO 1
|
||||||
|
recv DONT ECHO 0
|
||||||
|
recv DO ECHO 1
|
||||||
|
send WILL ECHO 0
|
||||||
|
(and the last 5 lines loop forever)
|
||||||
|
|
||||||
|
The line with the "***" is last of the WILL/DONT/WONT sequence.
|
||||||
|
The change to the server to not generate that makes this same
|
||||||
|
example become:
|
||||||
|
|
||||||
|
send will ECHO 1
|
||||||
|
send wont ECHO 2
|
||||||
|
recv do ECHO 1
|
||||||
|
send will ECHO 2
|
||||||
|
recv dont ECHO 1
|
||||||
|
recv dont ECHO 0
|
||||||
|
recv do ECHO 1
|
||||||
|
send will ECHO 0
|
||||||
|
|
||||||
|
There is other option negotiation going on, and not sending
|
||||||
|
the third part changes some of the timings, but this specific
|
||||||
|
example no longer gets stuck in a loop. The "telnet.state"
|
||||||
|
file has been modified to reflect this change to the algorithm.
|
||||||
|
|
||||||
|
A bunch of miscellaneous bug fixes and changes to make
|
||||||
|
lint happier.
|
||||||
|
|
||||||
|
This version of telnet also has some KERBEROS stuff in
|
||||||
|
it. This has not been tested, it uses an un-authorized
|
||||||
|
telnet option number, and uses an out-of-date version
|
||||||
|
of the (still being defined) AUTHENTICATION option.
|
||||||
|
There is no support for this code, do not enable it.
|
||||||
|
|
||||||
|
|
||||||
|
March 1, 1990:
|
||||||
|
CHANGES/BUGFIXES SINCE LAST RELEASE:
|
||||||
|
Some support for IP TOS has been added. Requires that the
|
||||||
|
kernel support the IP_TOS socket option (currently this
|
||||||
|
is only in UNICOS 6.0).
|
||||||
|
|
||||||
|
Both telnet and telnetd now use the cc_t typedef. typedefs are
|
||||||
|
included for systems that don't have it (in termios.h).
|
||||||
|
|
||||||
|
SLC_SUSP was not supported properly before. It is now.
|
||||||
|
|
||||||
|
IAC EOF was not translated properly in telnetd for SYSV_TERMIO
|
||||||
|
when not in linemode. It now saves a copy of the VEOF character,
|
||||||
|
so that when ICANON is turned off and we can't trust it anymore
|
||||||
|
(because it is now the VMIN character) we use the saved value.
|
||||||
|
|
||||||
|
There were two missing "break" commands in the linemode
|
||||||
|
processing code in telnetd.
|
||||||
|
|
||||||
|
Telnetd wasn't setting the kernel window size information
|
||||||
|
properly. It was using the rows for both rows and columns...

README: You are reading it.

|
|
||||||
|
Config.generic:
|
||||||
|
This file contains all the OS specific definitions. It
|
||||||
|
has pre-definitions for many common system types, and is
|
||||||
|
in standard makefile fromat. See the comments at the top
|
||||||
|
of the file for more information.
|
||||||
|
|
||||||
|
Config.local:
|
||||||
|
This is not part of the distribution, but if this file exists,
|
||||||
|
it is used instead of "Config.generic". This allows site
|
||||||
|
specific configuration without having to modify the distributed
|
||||||
|
"Config.generic" file.
|
||||||
|
|
||||||
|
kern.diff:
|
||||||
|
This file contains the diffs for the changes needed for the
|
||||||
|
kernel to support LINEMODE is the server. These changes are
|
||||||
|
for a 4.3BSD system. You may need to make some changes for
|
||||||
|
your particular system.
|
||||||
|
|
||||||
|
There is a new bit in the terminal state word, TS_EXTPROC.
|
||||||
|
When this bit is set, several aspects of the terminal driver
|
||||||
|
are disabled. Input line editing, character echo, and
|
||||||
|
mapping of signals are all disabled. This allows the telnetd
|
||||||
|
to turn of these functions when in linemode, but still keep
|
||||||
|
track of what state the user wants the terminal to be in.
|
||||||
|
|
||||||
|
New ioctl()s:
|
||||||
|
|
||||||
|
TIOCEXT Turn on/off the TS_EXTPROC bit
|
||||||
|
TIOCGSTATE Get t_state of tty to look at TS_EXTPROC bit
|
||||||
|
TIOCSIG Generate a signal to processes in the
|
||||||
|
current process group of the pty.
|
||||||
|
|
||||||
|
There is a new mode for packet driver, the TIOCPKT_IOCTL bit.
|
||||||
|
When packet mode is turned on in the pty, and the TS_EXTPROC
|
||||||
|
bit is set, then whenever the state of the pty is changed, the
|
||||||
|
next read on the master side of the pty will have the TIOCPKT_IOCTL
|
||||||
|
bit set, and the data will contain the following:
|
||||||
|
struct xx {
|
||||||
|
struct sgttyb a;
|
||||||
|
struct tchars b;
|
||||||
|
struct ltchars c;
|
||||||
|
int t_state;
|
||||||
|
int t_flags;
|
||||||
|
}
|
||||||
|
This allows the process on the server side of the pty to know
|
||||||
|
when the state of the terminal has changed, and what the new
|
||||||
|
state is.
|
||||||
|
|
||||||
|
However, if you define USE_TERMIO or SYSV_TERMIO, the code will
|
||||||
|
expect that the structure returned in the TIOCPKT_IOCTL is
|
||||||
|
the termio/termios structure.
|
||||||
|
|
||||||
|
stty.diff:
|
||||||
|
This file contains the changes needed for the stty(1) program
|
||||||
|
to report on the current status of the TS_EXTPROC bit. It also
|
||||||
|
allows the user to turn on/off the TS_EXTPROC bit. This is useful
|
||||||
|
because it allows the user to say "stty -extproc", and the
|
||||||
|
LINEMODE option will be automatically disabled, and saying "stty
|
||||||
|
extproc" will re-enable the LINEMODE option.
|
||||||
|
|
||||||
|
telnet.state:
|
||||||
|
Both the client and server have code in them to deal
|
||||||
|
with option negotiation loops. The algorithm that is
|
||||||
|
used is described in this file.
|
||||||
|
|
||||||
|
tmac.doc:
|
||||||
|
Macros for use in formatting the man pages on non-4.3Reno
|
||||||
|
systems.
|
||||||
|
|
||||||
|
telnet:
|
||||||
|
This directory contains the client code. No kernel changes are
|
||||||
|
needed to use this code.
|
||||||
|
|
||||||
|
telnetd:
|
||||||
|
This directory contains the server code. If LINEMODE or KLUDGELINEMODE
|
||||||
|
are defined, then the kernel modifications listed above are needed.
|
||||||
|
|
||||||
|
libtelnet:
|
||||||
|
This directory contains code that is common to both the client
|
||||||
|
and the server.
|
||||||
|
|
||||||
|
arpa:
|
||||||
|
This directory has a new <arpa/telnet.h>
|
||||||
|
|
||||||
|
|
||||||
|
The following TELNET options are supported:
|
||||||
|
|
||||||
|
LINEMODE:
|
||||||
|
The LINEMODE option is supported as per RFC1116. The
|
||||||
|
FORWARDMASK option is not currently supported.
|
||||||
|
|
||||||
|
BINARY: The client has the ability to turn on/off the BINARY
|
||||||
|
option in each direction. Turning on BINARY from
|
||||||
|
server to client causes the LITOUT bit to get set in
|
||||||
|
the terminal driver on both ends, turning on BINARY
|
||||||
|
from the client to the server causes the PASS8 bit
|
||||||
|
to get set in the terminal driver on both ends.
|
||||||
|
|
||||||
|
TERMINAL-TYPE:
|
||||||
|
This is supported as per RFC1091. On the server side,
|
||||||
|
when a terminal type is received, termcap/terminfo
|
||||||
|
is consulted to determine if it is a known terminal
|
||||||
|
type. It keeps requesting terminal types until it
|
||||||
|
gets one that it recongnizes, or hits the end of the
|
||||||
|
list. The server side looks up the entry in the
|
||||||
|
termcap/terminfo data base, and generates a list of
|
||||||
|
names which it then passes one at a time to each
|
||||||
|
request for a terminal type, duplicating the last
|
||||||
|
entry in the list before cycling back to the beginning.
|
||||||
|
|
||||||
|
NAWS: The Negotiate about Window Size, as per RFC 1073.
|
||||||
|
|
||||||
|
TERMINAL-SPEED:
|
||||||
|
Implemented as per RFC 1079
|
||||||
|
|
||||||
|
TOGGLE-FLOW-CONTROL:
|
||||||
|
Implemented as per RFC 1080
|
||||||
|
|
||||||
|
TIMING-MARK:
|
||||||
|
As per RFC 860
|
||||||
|
|
||||||
|
SGA: As per RFC 858
|
||||||
|
|
||||||
|
ECHO: As per RFC 857
|
||||||
|
|
||||||
|
STATUS:
|
||||||
|
The server will send its current status upon
|
||||||
|
request. It does not ask for the clients status.
|
||||||
|
The client will request the servers current status
|
||||||
|
from the "send getstatus" command.
|
||||||
|
|
||||||
|
ENVIRON:
|
||||||
|
This option is currently being defined by the IETF
|
||||||
|
Telnet Working Group, and an RFC has not yet been
|
||||||
|
issued, but should be in the near future...
|
||||||
|
|
||||||
|
X-DISPLAY-LOCATION:
|
||||||
|
This functionality can be done through the ENVIRON
|
||||||
|
option, it is added here for completeness.
|
||||||
|
|
||||||
|
AUTHENTICATION:
|
||||||
|
This option is currently being defined by the IETF
|
||||||
|
Telnet Working Group, and an RFC has not yet been
|
||||||
|
issued. The basic framework is pretty much decided,
|
||||||
|
but the definitions for the specific authentication
|
||||||
|
schemes is still in a state of flux.
|
||||||
|
|
||||||
|
ENCRYPT:
|
||||||
|
This option is currently being defined by the IETF
|
||||||
|
Telnet Working Group, and an RFC has not yet been
|
||||||
|
issued. The draft RFC is still in a state of flux,
|
||||||
|
so this code may change in the future.
