-2008-04-27 Love Hörnquist Åstrand <lha@it.su.se>
-
- * libtelnet/enc_des.c: Use RAND_bytes() + DES_is_weak_key() to
- generate random DES key. Introdunce random by feeding the des
- session key into the random pool when the keys is recived instead
- of encrypt the random key with the kerberos key.
-
- This avoid depenency on DES_new_random_key() that doesn't exists
- in OpenSSL.
-
-2008-04-18 Love Hörnquist Åstrand <lha@it.su.se>
-
- * libtelnet/enc_des.c: No need to call
- DES_init_random_number_generator, hcrypto is sane now.
-
- * libtelnet/enc_des.c: Use DES_new_random_key().

-
- * telnetd/sys_term.c: GLIBC made the choice that ut_tv should be
- shared between 32 and 64 bit platforms so now we can no longer use
- struct timeval functions to compare or set/get data that uses
- pointer (gettimeofday for example) since ut_tv is now not a struct
- timeval but rather a struct { int32_t tv_sec; int32_t tv_usec; };

-
- * telnet/telnet.c: From FreeBSD:
-
- Correct a pair of buffer overflows in the telnet(1) command:
-
- (CAN-2005-0468) A heap buffer overflow in env_opt_add() and related
- functions.
-
- (CAN-2005-0469) A global uninitialized data section buffer overflow in
- slc_add_reply() and related functions.
-
- As a result of these vulnerabilities, it may be possible for a
- malicious telnet server or active network attacker to cause
- telnet(1) to execute arbitrary code with the privileges of the
- user running it.

- quantities but time_t has gone up to 64 bits

-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.
-
-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 been assigned to, but it is still
- subject to change. 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", "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", and "help".
-
- The LOGOUT option is now supported by both telnet
- and telnetd, a new command, "logout", was added
- to support this.
-
- Several new toggle options were added:
- "autoencrypt", "autodecrypt", "autologin", "authdebug",
- "encdebug", "skiprc", "verbose_encrypt"
-
- 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:
-
- > *** tty_pty.c.ORG Tue Sep 11 09:41:53 1990
- > --- tty_pty.c Tue Sep 11 17:48:03 1990
- > ***************
- > *** 609,613 ****
- > if ((tp->t_lflag&NOFLSH) == 0)
- > ttyflush(tp, FREAD|FWRITE);

- > }
- > --- 609,616 ----

- > ! if ((*(unsigned int *)data == SIGINFO) &&
- > ! ((tp->t_lflag&NOKERNINFO) == 0))
- > ! ttyinfo(tp);
- > return(0);
- > }
-
- 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.
-
-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>
-
-libtelnet/Makefile.4.4:
-telnet/Makefile.4.4:
-telnetd/Makefile.4.4:
- These are the makefiles that can be used on a 4.3Reno
- system when this software is installed in /usr/src/lib/libtelnet,
- /usr/src/libexec/telnetd, and /usr/src/usr.bin/telnet.
-
-
-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
-
- LOGOUT: As per RFC 727
-
- 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.
-
- ENCRYPTION:
- 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.

- Three pieces of state need to be kept for each side of each option.
- (You need the localside, sending WILL/WONT & receiving DO/DONT, and
- the remoteside, sending DO/DONT and receiving WILL/WONT)
-
- MY_STATE: What state am I in?
- WANT_STATE: What state do I want?
- WANT_RESP: How many requests have I initiated?
-
- Default values:
- MY_STATE = WANT_STATE = DONT
- WANT_RESP = 0
-
- The local setup will change based on the state of the Telnet
- variables. When we are the originator, we can either make the
- local setup changes at option request time (in which case if
- the option is denied we need to change things back) or when
- the option is acknowledged.
-
- To initiate a switch to NEW_STATE:
-
- if ((WANT_RESP == 0 && NEW_STATE == MY_STATE) ||
- WANT_STATE == NEW_STATE) {
- do nothing;
- } else {
- /*
- * This is where the logic goes to change the local setup
- * if we are doing so at request initiation
- */
- WANT_STATE = NEW_STATE;
- send NEW_STATE;
- WANT_RESP += 1;
- }
-
- When receiving NEW_STATE:
-
- if (WANT_RESP) {
- --WANT_RESP;
- if (WANT_RESP && (NEW_STATE == MY_STATE))
- --WANT_RESP;
- }
- if (WANT_RESP == 0) {
- if (NEW_STATE != WANT_STATE) {
- /*
- * This is where the logic goes to decide if it is ok
- * to switch to NEW_STATE, and if so, do any necessary
- * local setup changes.
- */
- if (ok_to_switch_to NEW_STATE)
- WANT_STATE = NEW_STATE;
- else
- WANT_RESP++;
-* if (MY_STATE != WANT_STATE)
- reply with WANT_STATE;
- } else {
- /*
- * This is where the logic goes to change the local setup
- * if we are doing so at request acknowledgment
- */
- }
- }
- MY_STATE = NEW_STATE;
-
-* This if() line is not needed, it should be ok to always do the
- "reply with WANT_STATE". With the if() line, asking to turn on
- an option that the other side doesn't understand is:
- Send DO option
- Recv WONT option
- Without the if() line, it is:
- Send DO option
- Recv WONT option
- Send DONT option
- If the other side does not expect to receive the latter case,
- but generates the latter case, then there is a potential for
- option negotiation loops. An implementation that does not expect
- to get the second case should not generate it, an implementation
- that does expect to get it may or may not generate it, and things
- will still work. Being conservative in what we send, we have the
- if() statement in, but we expect the other side to generate the
- last response.

-.Sh NAME
-.Nm telnet
-.Nd user interface to the
-.Tn TELNET
-protocol
-.Sh SYNOPSIS
-.Nm telnet
-.Op Fl 78EFKLacdfrx
-.Op Fl S Ar tos
-.Op Fl X Ar authtype
-.Op Fl e Ar escapechar
-.Op Fl k Ar realm
-.Op Fl l Ar user
-.Op Fl n Ar tracefile
-.Oo
-.Ar host
-.Op port
-.Oc
-.Sh DESCRIPTION
-The
-.Nm telnet
-command
-is used to communicate with another host using the
-.Tn TELNET
-protocol.
-If
-.Nm telnet
-is invoked without the
-.Ar host
-argument, it enters command mode,
-indicated by its prompt
-.Pq Nm telnet\*[Gt] .
-In this mode, it accepts and executes the commands listed below.
-If it is invoked with arguments, it performs an
-.Ic open
-command with those arguments.
-.Pp
-Options:
-.Bl -tag -width indent
-.It Fl 8
-Specifies an 8-bit data path. This causes an attempt to
-negotiate the
-.Dv TELNET BINARY
-option on both input and output.
-.It Fl 7
-Do not try to negotiate
-.Dv TELNET BINARY
-option.
-.It Fl E
-Stops any character from being recognized as an escape character.
-.It Fl F
-If Kerberos V5 authentication is being used, the
-.Fl F
-option allows the local credentials to be forwarded
-to the remote system, including any credentials that
-have already been forwarded into the local environment.
-.It Fl K
-Specifies no automatic login to the remote system.
-.It Fl L
-Specifies an 8-bit data path on output. This causes the
-BINARY option to be negotiated on output.
-.It Fl S Ar tos
-Sets the IP type-of-service (TOS) option for the telnet
-connection to the value
-.Ar tos ,
-which can be a numeric TOS value
-or, on systems that support it, a symbolic
-TOS name found in the /etc/iptos file.
-.It Fl X Ar atype
-Disables the
-.Ar atype
-type of authentication.
-.It Fl a
-Attempt automatic login.
-Currently, this sends the user name via the
-.Ev USER
-variable
-of the
-.Ev ENVIRON
-option if supported by the remote system.
-The name used is that of the current user as returned by
-.Xr getlogin 2
-if it agrees with the current user ID,
-otherwise it is the name associated with the user ID.
-.It Fl c
-Disables the reading of the user's
-.Pa \&.telnetrc
-file. (See the
-.Ic toggle skiprc
-command on this man page.)
-.It Fl d
-Sets the initial value of the
-.Ic debug
-toggle to
-.Dv TRUE
-.It Fl e Ar escape char
-Sets the initial
-.Nm
-.Nm telnet
-escape character to
-.Ar escape char .
-If
-.Ar escape char
-is omitted, then
-there will be no escape character.
-.It Fl f
-If Kerberos V5 authentication is being used, the
-.Fl f
-option allows the local credentials to be forwarded to the remote system.
-.It Fl k Ar realm
-If Kerberos authentication is being used, the
-.Fl k
-option requests that telnet obtain tickets for the remote host in
-realm realm instead of the remote host's realm, as determined
-by
-.Xr krb_realmofhost 3 .
-.It Fl l Ar user
-When connecting to the remote system, if the remote system
-understands the
-.Ev ENVIRON

-command.
-.It Fl n Ar tracefile
-Opens
-.Ar tracefile
-for recording trace information.
-See the
-.Ic set tracefile
-command below.
-.It Fl r
-Specifies a user interface similar to
-.Xr rlogin 1 .
-In this
-mode, the escape character is set to the tilde (~) character,
-unless modified by the -e option.
-.It Fl x
-Turn on encryption of the data stream. When this option is turned on,
-.B telnet
-will exit with an error if authentication cannot be negotiated or if
-encryption cannot be turned on.
-.It Ar host
-Indicates the official name, an alias, or the Internet address
-of a remote host.
-.It Ar port
-Indicates a port number (address of an application). If a number is
-not specified, the default
-.Nm telnet
-port is used.
-.El
-.Pp
-When in rlogin mode, a line of the form ~. disconnects from the
-remote host; ~ is the telnet escape character.
-Similarly, the line ~^Z suspends the telnet session.
-The line ~^] escapes to the normal telnet escape prompt.
-.Pp
-Once a connection has been opened,
-.Nm telnet
-will attempt to enable the
-.Dv TELNET LINEMODE
-option.
-If this fails, then
-.Nm telnet
-will revert to one of two input modes:
-either \*(Lqcharacter at a time\*(Rq
-or \*(Lqold line by line\*(Rq
-depending on what the remote system supports.
-.Pp
-When
-.Dv LINEMODE
-is enabled, character processing is done on the
-local system, under the control of the remote system. When input
-editing or character echoing is to be disabled, the remote system
-will relay that information. The remote system will also relay
-changes to any special characters that happen on the remote
-system, so that they can take effect on the local system.
-.Pp
-In \*(Lqcharacter at a time\*(Rq mode, most
-text typed is immediately sent to the remote host for processing.
-.Pp
-In \*(Lqold line by line\*(Rq mode, all text is echoed locally,
-and (normally) only completed lines are sent to the remote host.
-The \*(Lqlocal echo character\*(Rq (initially \*(Lq^E\*(Rq) may be used
-to turn off and on the local echo
-(this would mostly be used to enter passwords
-without the password being echoed).
-.Pp
-If the

-.Ic localchars
-toggle is
-.Dv TRUE
-(the default for \*(Lqold line by line\*(Lq; see below),
-the user's
-.Ic quit ,
-.Ic intr ,
-and
-.Ic flush
-characters are trapped locally, and sent as
-.Tn TELNET
-protocol sequences to the remote side.
-If
-.Dv LINEMODE
-has ever been enabled, then the user's
-.Ic susp
-and
-.Ic eof
-are also sent as
-.Tn TELNET
-protocol sequences,
-and
-.Ic quit
-is sent as a
-.Dv TELNET ABORT
-instead of
-.Dv BREAK
-There are options (see
-.Ic toggle
-.Ic autoflush
-and
-.Ic toggle
-.Ic autosynch
-below)
-which cause this action to flush subsequent output to the terminal
-(until the remote host acknowledges the

-.Pp
-While connected to a remote host,
-.Nm telnet
-command mode may be entered by typing the

-Toggle carriage return mode.
-When this mode is enabled, most carriage return characters received from
-the remote host will be mapped into a carriage return followed by
-a line feed.
-This mode does not affect those characters typed by the user, only
-those received from the remote host.
-This mode is not very useful unless the remote host
-only sends carriage return, but never line feed.
-The initial value for this toggle is

-If
-.Dv LINEMODE
-has ever been enabled, then
-.Ic quit
-is sent as
-.Ic abort ,
-and
-.Ic eof
-and
-.Ic suspend
-are sent as
-.Ic eof
-and

-Spaces are put between each character in the output, and the
-beginning of any
-.Tn TELNET
-escape sequence is preceded by a '*' to aid in locating them.
-.It Ic skiprc
-When the skiprc toggle is
-.Dv TRUE ,
-.Tn TELNET
-skips the reading of the

-The initial value for this toggle is
-.Dv FALSE .
-.It Ic verbose_encrypt
-When the
-.Ic verbose_encrypt
-toggle is
-.Dv TRUE ,
-.Tn TELNET
-prints out a message each time encryption is enabled or
-disabled. The initial value for this toggle is
-.Dv FALSE .
-Note: Because of export controls, data encryption
-is not supported outside of the United States and Canada.
-.It Ic \&?
-Displays the legal
-.Ic toggle
-commands.
-.El
-.It Ic z
-Suspend
-.Nm telnet .
-This command only works when the user is using the

-DDEESSCCRRIIPPTTIIOONN
- The tteellnneett command is used to communicate with another host using the
- TELNET protocol. If tteellnneett is invoked without the _h_o_s_t argument, it
- enters command mode, indicated by its prompt (tteellnneett>>). In this mode, it
- accepts and executes the commands listed below. If it is invoked with
- arguments, it performs an ooppeenn command with those arguments.
-
- Options:
-
- --88 Specifies an 8-bit data path. This causes an attempt to negoti-
- ate the TELNET BINARY option on both input and output.
-
- --77 Do not try to negotiate TELNET BINARY option.
-
- --EE Stops any character from being recognized as an escape character.
-
- --FF If Kerberos V5 authentication is being used, the --FF option allows
- the local credentials to be forwarded to the remote system,
- including any credentials that have already been forwarded into
- the local environment.
-
- --KK Specifies no automatic login to the remote system.
-
- --LL Specifies an 8-bit data path on output. This causes the BINARY
- option to be negotiated on output.
-
- --SS _t_o_s Sets the IP type-of-service (TOS) option for the telnet connec-
- tion to the value _t_o_s, which can be a numeric TOS value or, on
- systems that support it, a symbolic TOS name found in the
- /etc/iptos file.
-
- --XX _a_t_y_p_e
- Disables the _a_t_y_p_e type of authentication.
-
- --aa Attempt automatic login. Currently, this sends the user name via
- the USER variable of the ENVIRON option if supported by the
- remote system. The name used is that of the current user as
- returned by getlogin(2) if it agrees with the current user ID,
- otherwise it is the name associated with the user ID.
-
- --cc Disables the reading of the user's _._t_e_l_n_e_t_r_c file. (See the
- ttooggggllee sskkiipprrcc command on this man page.)
-
- --dd Sets the initial value of the ddeebbuugg toggle to TRUE
-
- --ee _e_s_c_a_p_e _c_h_a_r
- Sets the initial tteellnneett tteellnneett escape character to _e_s_c_a_p_e _c_h_a_r.
- If _e_s_c_a_p_e _c_h_a_r is omitted, then there will be no escape charac-
- ter.
-
- --ff If Kerberos V5 authentication is being used, the --ff option allows
- the local credentials to be forwarded to the remote system.
-
- --kk _r_e_a_l_m
- If Kerberos authentication is being used, the --kk option requests
- that telnet obtain tickets for the remote host in realm realm
- instead of the remote host's realm, as determined by
- krb_realmofhost(3).
-
- --ll _u_s_e_r
- When connecting to the remote system, if the remote system under-
- stands the ENVIRON option, then _u_s_e_r will be sent to the remote
- system as the value for the variable USER. This option implies
- the --aa option. This option may also be used with the ooppeenn com-
- mand.
-
- --nn _t_r_a_c_e_f_i_l_e
- Opens _t_r_a_c_e_f_i_l_e for recording trace information. See the sseett
- ttrraacceeffiillee command below.
-
- --rr Specifies a user interface similar to rlogin(1). In this mode,
- the escape character is set to the tilde (~) character, unless
- modified by the -e option.
-
- --xx Turn on encryption of the data stream. When this option is
- turned on, will exit with an error if authentication cannot be
- negotiated or if encryption cannot be turned on.
-
- _h_o_s_t Indicates the official name, an alias, or the Internet address of
- a remote host.
-
- _p_o_r_t Indicates a port number (address of an application). If a number
- is not specified, the default tteellnneett port is used.
-
- When in rlogin mode, a line of the form ~. disconnects from the remote
- host; ~ is the telnet escape character. Similarly, the line ~^Z suspends
- the telnet session. The line ~^] escapes to the normal telnet escape
- prompt.
-
- Once a connection has been opened, tteellnneett will attempt to enable the
- TELNET LINEMODE option. If this fails, then tteellnneett will revert to one of
- two input modes: either ``character at a time'' or ``old line by line''
- depending on what the remote system supports.
-
- When LINEMODE is enabled, character processing is done on the local sys-
- tem, under the control of the remote system. When input editing or char-
- acter echoing is to be disabled, the remote system will relay that infor-
- mation. The remote system will also relay changes to any special charac-
- ters that happen on the remote system, so that they can take effect on
- the local system.
-
- In ``character at a time'' mode, most text typed is immediately sent to
- the remote host for processing.
-
- In ``old line by line'' mode, all text is echoed locally, and (normally)
- only completed lines are sent to the remote host. The ``local echo char-
- acter'' (initially ``^E'') may be used to turn off and on the local echo
- (this would mostly be used to enter passwords without the password being
- echoed).
-
- If the LINEMODE option is enabled, or if the llooccaallcchhaarrss toggle is TRUE
- (the default for ``old line by line``; see below), the user's qquuiitt, iinnttrr,
- and fflluusshh characters are trapped locally, and sent as TELNET protocol
- sequences to the remote side. If LINEMODE has ever been enabled, then
- the user's ssuusspp and eeooff are also sent as TELNET protocol sequences, and
- qquuiitt is sent as a TELNET ABORT instead of BREAK There are options (see
- ttooggggllee aauuttoofflluusshh and ttooggggllee aauuttoossyynncchh below) which cause this action to
- flush subsequent output to the terminal (until the remote host acknowl-
- edges the TELNET sequence) and flush previous terminal input (in the case
- of qquuiitt and iinnttrr).
-
- While connected to a remote host, tteellnneett command mode may be entered by
- typing the tteellnneett ``escape character'' (initially ``^]''). When in com-
- mand mode, the normal terminal editing conventions are available.
-
- The following tteellnneett commands are available. Only enough of each command
- to uniquely identify it need be typed (this is also true for arguments to
- the mmooddee, sseett, ttooggggllee, uunnsseett, ssllcc, eennvviirroonn, and ddiissppllaayy commands).
-
- aauutthh _a_r_g_u_m_e_n_t _._._.
- The auth command manipulates the information sent through the
- TELNET AUTHENTICATE option. Valid arguments for the auth com-
- mand are as follows:
-
- ddiissaabbllee _t_y_p_e Disables the specified type of authentication.
- To obtain a list of available types, use the
- aauutthh ddiissaabbllee ?? command.
-
- eennaabbllee _t_y_p_e Enables the specified type of authentication.
- To obtain a list of available types, use the
- aauutthh eennaabbllee ?? command.
-
- ssttaattuuss Lists the current status of the various types of
- authentication.
-
- cclloossee Close a TELNET session and return to command mode.
-
- ddiissppllaayy _a_r_g_u_m_e_n_t _._._.
- Displays all, or some, of the sseett and ttooggggllee values (see
- below).
-
- eennccrryypptt _a_r_g_u_m_e_n_t _._._.
- The encrypt command manipulates the information sent through
- the TELNET ENCRYPT option.
-
- Note: Because of export controls, the TELNET ENCRYPT option
- is not supported outside of the United States and Canada.
-
- Valid arguments for the encrypt command are as follows:
-
- ddiissaabbllee _t_y_p_e [iinnppuutt | oouuttppuutt]
- Disables the specified type of encryption. If
- you omit the input and output, both input and
- output are disabled. To obtain a list of avail-
- able types, use the eennccrryypptt ddiissaabbllee ?? command.
-
- eennaabbllee _t_y_p_e [iinnppuutt | oouuttppuutt]
- Enables the specified type of encryption. If
- you omit input and output, both input and output
- are enabled. To obtain a list of available
- types, use the eennccrryypptt eennaabbllee ?? command.
-
- iinnppuutt This is the same as the eennccrryypptt ssttaarrtt iinnppuutt com-
- mand.
-
- --iinnppuutt This is the same as the eennccrryypptt ssttoopp iinnppuutt com-
- mand.
-
- oouuttppuutt This is the same as the eennccrryypptt ssttaarrtt oouuttppuutt
- command.
-
- --oouuttppuutt This is the same as the eennccrryypptt ssttoopp oouuttppuutt com-
- mand.
-
- ssttaarrtt [iinnppuutt | oouuttppuutt]
- Attempts to start encryption. If you omit iinnppuutt
- and oouuttppuutt, both input and output are enabled.
- To obtain a list of available types, use the
- eennccrryypptt eennaabbllee ?? command.
-
- ssttaattuuss Lists the current status of encryption.
-
- ssttoopp [iinnppuutt | oouuttppuutt]
- Stops encryption. If you omit input and output,
- encryption is on both input and output.
-
- ttyyppee _t_y_p_e Sets the default type of encryption to be used
- with later eennccrryypptt ssttaarrtt or eennccrryypptt ssttoopp com-
- mands.
-
- eennvviirroonn _a_r_g_u_m_e_n_t_s _._._.
- The eennvviirroonn command is used to manipulate the the variables
- that my be sent through the TELNET ENVIRON option. The ini-
- tial set of variables is taken from the users environment,
- with only the DISPLAY and PRINTER variables being exported by
- default. The USER variable is also exported if the --aa or --ll
- options are used.
-
- Valid arguments for the eennvviirroonn command are:
-
- ddeeffiinnee _v_a_r_i_a_b_l_e _v_a_l_u_e
- Define the variable _v_a_r_i_a_b_l_e to have a value of
- _v_a_l_u_e. Any variables defined by this command are
- automatically exported. The _v_a_l_u_e may be enclosed
- in single or double quotes so that tabs and spaces
- may be included.
-
- uunnddeeffiinnee _v_a_r_i_a_b_l_e
- Remove _v_a_r_i_a_b_l_e from the list of environment vari-
- ables.
-
- eexxppoorrtt _v_a_r_i_a_b_l_e
- Mark the variable _v_a_r_i_a_b_l_e to be exported to the
- remote side.
-
- uunneexxppoorrtt _v_a_r_i_a_b_l_e
- Mark the variable _v_a_r_i_a_b_l_e to not be exported
- unless explicitly asked for by the remote side.
-
- lliisstt List the current set of environment variables.
- Those marked with a ** will be sent automatically,
- other variables will only be sent if explicitly
- requested.
-
- ?? Prints out help information for the eennvviirroonn com-
- mand.
-
- llooggoouutt Sends the TELNET LOGOUT option to the remote side. This com-
- mand is similar to a cclloossee command; however, if the remote
- side does not support the LOGOUT option, nothing happens. If,
- however, the remote side does support the LOGOUT option, this
- command should cause the remote side to close the TELNET con-
- nection. If the remote side also supports the concept of sus-
- pending a user's session for later reattachment, the logout
- argument indicates that you should terminate the session imme-
- diately.
-
- mmooddee _t_y_p_e _T_y_p_e is one of several options, depending on the state of the
- TELNET session. The remote host is asked for permission to go
- into the requested mode. If the remote host is capable of
- entering that mode, the requested mode will be entered.
-
- cchhaarraacctteerr Disable the TELNET LINEMODE option, or, if the
- remote side does not understand the LINEMODE
- option, then enter ``character at a time`` mode.
-
- lliinnee Enable the TELNET LINEMODE option, or, if the
- remote side does not understand the LINEMODE
- option, then attempt to enter ``old-line-by-
- line`` mode.
-
- iissiigg (--iissiigg) Attempt to enable (disable) the TRAPSIG mode of
- the LINEMODE option. This requires that the
- LINEMODE option be enabled.
-
- eeddiitt (--eeddiitt) Attempt to enable (disable) the EDIT mode of the
- LINEMODE option. This requires that the
- LINEMODE option be enabled.
-
- ssooffttttaabbss (--ssooffttttaabbss)
- Attempt to enable (disable) the SOFT_TAB mode of
- the LINEMODE option. This requires that the
- LINEMODE option be enabled.
-
- lliitteecchhoo (--lliitteecchhoo)
- Attempt to enable (disable) the LIT_ECHO mode of
- the LINEMODE option. This requires that the
- LINEMODE option be enabled.
-
- ?? Prints out help information for the mmooddee com-
- mand.
-
- ooppeenn _h_o_s_t [--ll _u_s_e_r] [[--]_p_o_r_t]
- Open a connection to the named host. If no port number is
- specified, tteellnneett will attempt to contact a TELNET server at
- the default port. The host specification may be either a host
- name (see hosts(5)) or an Internet address specified in the
- ``dot notation'' (see inet(3)). The [--ll] option may be used
- to specify the user name to be passed to the remote system via
- the ENVIRON option. When connecting to a non-standard port,
- tteellnneett omits any automatic initiation of TELNET options. When
- the port number is preceded by a minus sign, the initial
- option negotiation is done. After establishing a connection,
- the file _._t_e_l_n_e_t_r_c in the users home directory is opened.
- Lines beginning with a # are comment lines. Blank lines are
- ignored. Lines that begin without white space are the start
- of a machine entry. The first thing on the line is the name
- of the machine that is being connected to. The rest of the
- line, and successive lines that begin with white space are
- assumed to be tteellnneett commands and are processed as if they had
- been typed in manually to the tteellnneett command prompt.
-
- qquuiitt Close any open TELNET session and exit tteellnneett. An end of file
- (in command mode) will also close a session and exit.
-
- sseenndd _a_r_g_u_m_e_n_t_s
- Sends one or more special character sequences to the remote
- host. The following are the arguments which may be specified
- (more than one argument may be specified at a time):
-
- aabboorrtt Sends the TELNET ABORT (Abort processes) sequence.
-
- aaoo Sends the TELNET AO (Abort Output) sequence, which
- should cause the remote system to flush all output
- _f_r_o_m the remote system _t_o the user's terminal.
-
- aayytt Sends the TELNET AYT (Are You There) sequence, to
- which the remote system may or may not choose to
- respond.
-
- bbrrkk Sends the TELNET BRK (Break) sequence, which may have
- significance to the remote system.
-
- eecc Sends the TELNET EC (Erase Character) sequence, which
- should cause the remote system to erase the last char-
- acter entered.
-
- eell Sends the TELNET EL (Erase Line) sequence, which
- should cause the remote system to erase the line cur-
- rently being entered.
-
- eeooff Sends the TELNET EOF (End Of File) sequence.
-
- eeoorr Sends the TELNET EOR (End of Record) sequence.
-
- eessccaappee Sends the current tteellnneett escape character (initially
- ``^'').
-
- ggaa Sends the TELNET GA (Go Ahead) sequence, which likely
- has no significance to the remote system.
-
- ggeettssttaattuuss
- If the remote side supports the TELNET STATUS command,
- ggeettssttaattuuss will send the subnegotiation to request that
- the server send its current option status.
-
- iipp Sends the TELNET IP (Interrupt Process) sequence,
- which should cause the remote system to abort the cur-
- rently running process.
-
- nnoopp Sends the TELNET NOP (No OPeration) sequence.
-
- ssuusspp Sends the TELNET SUSP (SUSPend process) sequence.
-
- ssyynncchh Sends the TELNET SYNCH sequence. This sequence causes
- the remote system to discard all previously typed (but
- not yet read) input. This sequence is sent as TCP
- urgent data (and may not work if the remote system is
- a 4.2BSD system -- if it doesn't work, a lower case
- ``r'' may be echoed on the terminal).
-
- ddoo _c_m_d
-
- ddoonntt _c_m_d
-
- wwiillll _c_m_d
-
- wwoonntt _c_m_d
- Sends the TELNET DO _c_m_d sequence. _C_m_d can be either a
- decimal number between 0 and 255, or a symbolic name
- for a specific TELNET command. _C_m_d can also be either
- hheellpp or ?? to print out help information, including a
- list of known symbolic names.
-
- ?? Prints out help information for the sseenndd command.
-
- sseett _a_r_g_u_m_e_n_t _v_a_l_u_e
-
- uunnsseett _a_r_g_u_m_e_n_t _v_a_l_u_e
- The sseett command will set any one of a number of tteellnneett vari-
- ables to a specific value or to TRUE. The special value ooffff
- turns off the function associated with the variable, this is
- equivalent to using the uunnsseett command. The uunnsseett command will
- disable or set to FALSE any of the specified functions. The
- values of variables may be interrogated with the ddiissppllaayy com-
- mand. The variables which may be set or unset, but not tog-
- gled, are listed here. In addition, any of the variables for
- the ttooggggllee command may be explicitly set or unset using the
- sseett and uunnsseett commands.
-
- aayytt If TELNET is in localchars mode, or LINEMODE is
- enabled, and the status character is typed, a TELNET
- AYT sequence (see sseenndd aayytt preceding) is sent to the
- remote host. The initial value for the "Are You
- There" character is the terminal's status character.
-
- eecchhoo This is the value (initially ``^E'') which, when in
- ``line by line'' mode, toggles between doing local
- echoing of entered characters (for normal processing),
- and suppressing echoing of entered characters (for
- entering, say, a password).
-
- eeooff If tteellnneett is operating in LINEMODE or ``old line by
- line'' mode, entering this character as the first
- character on a line will cause this character to be
- sent to the remote system. The initial value of the
- eof character is taken to be the terminal's eeooff char-
- acter.
-
- eerraassee If tteellnneett is in llooccaallcchhaarrss mode (see ttooggggllee llooccaallcchhaarrss
- below), aanndd if tteellnneett is operating in ``character at a
- time'' mode, then when this character is typed, a
- TELNET EC sequence (see sseenndd eecc above) is sent to the
- remote system. The initial value for the erase char-
- acter is taken to be the terminal's eerraassee character.
-
- eessccaappee This is the tteellnneett escape character (initially ``^['')
- which causes entry into tteellnneett command mode (when con-
- nected to a remote system).
-
- fflluusshhoouuttppuutt
- If tteellnneett is in llooccaallcchhaarrss mode (see ttooggggllee llooccaallcchhaarrss
- below) and the fflluusshhoouuttppuutt character is typed, a
- TELNET AO sequence (see sseenndd aaoo above) is sent to the
- remote host. The initial value for the flush charac-
- ter is taken to be the terminal's fflluusshh character.
-
- ffoorrww11
-
- ffoorrww22 If TELNET is operating in LINEMODE, these are the
- characters that, when typed, cause partial lines to be
- forwarded to the remote system. The initial value for
- the forwarding characters are taken from the termi-
- nal's eol and eol2 characters.
-
- iinntteerrrruupptt
- If tteellnneett is in llooccaallcchhaarrss mode (see ttooggggllee llooccaallcchhaarrss
- below) and the iinntteerrrruupptt character is typed, a TELNET
- IP sequence (see sseenndd iipp above) is sent to the remote
- host. The initial value for the interrupt character
- is taken to be the terminal's iinnttrr character.
-
- kkiillll If tteellnneett is in llooccaallcchhaarrss mode (see ttooggggllee llooccaallcchhaarrss
- below), aanndd if tteellnneett is operating in ``character at a
- time'' mode, then when this character is typed, a
- TELNET EL sequence (see sseenndd eell above) is sent to the
- remote system. The initial value for the kill charac-
- ter is taken to be the terminal's kkiillll character.
-
- llnneexxtt If tteellnneett is operating in LINEMODE or ``old line by
- line`` mode, then this character is taken to be the
- terminal's llnneexxtt character. The initial value for the
- lnext character is taken to be the terminal's llnneexxtt
- character.
-
- qquuiitt If tteellnneett is in llooccaallcchhaarrss mode (see ttooggggllee llooccaallcchhaarrss
- below) and the qquuiitt character is typed, a TELNET BRK
- sequence (see sseenndd bbrrkk above) is sent to the remote
- host. The initial value for the quit character is
- taken to be the terminal's qquuiitt character.
-
- rreepprriinntt
- If tteellnneett is operating in LINEMODE or ``old line by
- line`` mode, then this character is taken to be the
- terminal's rreepprriinntt character. The initial value for
- the reprint character is taken to be the terminal's
- rreepprriinntt character.
-
- rrllooggiinn This is the rlogin escape character. If set, the nor-
- mal TELNET escape character is ignored unless it is
- preceded by this character at the beginning of a line.
- This character, at the beginning of a line followed by
- a "." closes the connection; when followed by a ^Z it
- suspends the telnet command. The initial state is to
- disable the rlogin escape character.
-
- ssttaarrtt If the TELNET TOGGLE-FLOW-CONTROL option has been
- enabled, then this character is taken to be the termi-
- nal's ssttaarrtt character. The initial value for the kill
- character is taken to be the terminal's ssttaarrtt charac-
- ter.
-
- ssttoopp If the TELNET TOGGLE-FLOW-CONTROL option has been
- enabled, then this character is taken to be the termi-
- nal's ssttoopp character. The initial value for the kill
- character is taken to be the terminal's ssttoopp charac-
- ter.
-
- ssuusspp If tteellnneett is in llooccaallcchhaarrss mode, or LINEMODE is
- enabled, and the ssuussppeenndd character is typed, a TELNET
- SUSP sequence (see sseenndd ssuusspp above) is sent to the
- remote host. The initial value for the suspend char-
- acter is taken to be the terminal's ssuussppeenndd character.
-
- ttrraacceeffiillee
- This is the file to which the output, caused by
- nneettddaattaa or ooppttiioonn tracing being TRUE, will be written.
- If it is set to ``--'', then tracing information will
- be written to standard output (the default).
-
- wwoorrddeerraassee
- If tteellnneett is operating in LINEMODE or ``old line by
- line`` mode, then this character is taken to be the
- terminal's wwoorrddeerraassee character. The initial value for
- the worderase character is taken to be the terminal's
- wwoorrddeerraassee character.
-
- ?? Displays the legal sseett (uunnsseett) commands.
-
- ssllcc _s_t_a_t_e The ssllcc command (Set Local Characters) is used to set or
- change the state of the the special characters when the TELNET
- LINEMODE option has been enabled. Special characters are
- characters that get mapped to TELNET commands sequences (like
- iipp or qquuiitt) or line editing characters (like eerraassee and kkiillll).
- By default, the local special characters are exported.
-
- cchheecckk Verify the current settings for the current spe-
- cial characters. The remote side is requested to
- send all the current special character settings,
- and if there are any discrepancies with the local
- side, the local side will switch to the remote
- value.
-
- eexxppoorrtt Switch to the local defaults for the special char-
- acters. The local default characters are those of
- the local terminal at the time when tteellnneett was
- started.
-
- iimmppoorrtt Switch to the remote defaults for the special
- characters. The remote default characters are
- those of the remote system at the time when the
- TELNET connection was established.
-
- ?? Prints out help information for the ssllcc command.
-
- ssttaattuuss Show the current status of tteellnneett. This includes the peer one
- is connected to, as well as the current mode.
-
- ttooggggllee _a_r_g_u_m_e_n_t_s _._._.
- Toggle (between TRUE and FALSE) various flags that control how
- tteellnneett responds to events. These flags may be set explicitly
- to TRUE or FALSE using the sseett and uunnsseett commands listed
- above. More than one argument may be specified. The state of
- these flags may be interrogated with the ddiissppllaayy command.
- Valid arguments are:
-
- aauutthhddeebbuugg Turns on debugging information for the authenti-
- cation code.
-
- aauuttoofflluusshh If aauuttoofflluusshh and llooccaallcchhaarrss are both TRUE, then
- when the aaoo, or qquuiitt characters are recognized
- (and transformed into TELNET sequences; see sseett
- above for details), tteellnneett refuses to display
