NAME
       telnet -	user interface to a remote system using	the TELNET protocol

SYNOPSIS
       telnet  [-8EFKLacdfrx] [-X atype] [-e escape_char] [-k realm] [-l user]
       [-n file] [ [ [!] @hop1 [ @hop2...] @] host [port]]

       The telnet utility communicates with another host using the TELNET pro-
       tocol.  If telnet is invoked without arguments, it enters command mode,
       indicated by its	prompt,	telnet>. In this mode, it accepts and executes
       its associated commands.	See , telnet Commands, below. If it is invoked
       with arguments, it performs an open command with	those arguments.

       If, for example,	a host is specified as @hop1@hop2@host,	the connection
       goes  through hosts hop1	and hop2, using	loose source routing to	end at
       host. If	a leading ! is used,  the  connection  follows	strict	source
       routing.	 Note that when	telnet uses IPv6, it can only use loose	source
       routing,	and the	connection ignores the !.

       Once a connection has been opened, telnet enters	input  mode.  In  this
       mode,  text  typed  is  sent to the remote host.	The input mode entered
       will be either "line mode", "character at a  time",  or	"old  line  by
       line", depending	upon what the remote system supports.

       In "line	mode", character processing is done on the local system, under
       the control of the remote system. When input editing or character echo-
       ing  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.

       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.
       (Use  this  mostly  to  enter  passwords	 without  the  password	 being
       echoed.).

       If  the	"line  mode" option is enabled,	or if the localchars toggle is
       TRUE (the default in "old line by line" mode), the user's  quit,	 intr,
       and  flush  characters are trapped locally, and sent as TELNET protocol
       sequences to the	remote side. If	"line mode"  has  ever	been  enabled,
       then  the  user's  susp	and  eof  are also sent	as TELNET protocol se-
       quences.	quit is	then sent as a TELNET ABORT instead of BREAK. The  op-
       tions  toggle autoflush and toggle autosynch cause this action to flush
       subsequent output to the	terminal (until	the remote  host  acknowledges
       the TELNET sequence); and to flush previous terminal input, in the case
       of quit and intr.

       While connected to a remote host, the user  can	enter  telnet  command
       mode by typing the telnet escape	character (initially ^]). When in com-
       mand mode, the  normal  terminal	 editing  conventions  are  available.
       Pressing	 <RETURN>  at  the telnet command prompt causes	telnet to exit
       command mode.

       The following options are supported:

       -8	       Specifies an 8-bit data path.  Negotiating  the	TELNET
		       BINARY option is	attempted for both input and output.

       -a	       Attempts	 automatic  login. This	sends the user name by
		       means of	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(3C)	if  it
		       agrees  with  the current user ID. Otherwise, it	is the
		       name associated with the	user ID.

       -c	       Disables	the reading of the user's telnetrc file.  (See
		       the toggle skiprc command on this reference page.)

       -d	       Sets the	initial	value of the debug toggle to TRUE.

       -e escape_char  Sets  the  initial escape character to escape_char. es-
		       cape_char may also be a two character sequence consist-
		       ing  of	'^'  followed by one character.	 If the	second
		       character is '?', the DEL character is selected.	Other-
		       wise,  the  second  character is	converted to a control
		       character and used as the escape	character. If the  es-
		       cape  character is the null string (that	is, -e ''), it
		       is disabled.

       -E	       Stops any character from	being recognized as an	escape
		       character.

       -f	       Forwards	 a copy	of the local credentials to the	remote
		       system.

       -F	       Forwards	a forwardable copy of the local	credentials to
		       the remote system.

       -k realm	       If Kerberos authentication is being used, requests that
		       telnet obtain tickets for the remote host in realm  in-
		       stead  of the remote host's default realm as determined
		       inkrb5.conf(4).

       -K	       Specifies no automatic login to the remote system.

       -l user	       When connecting to a remote system that understands the
		       ENVIRON	option,	 then  user will be sent to the	remote
		       system as the value for the ENVIRON variable USER.

       -L	       Specifies an 8-bit data path on output. This causes the
		       BINARY option to	be negotiated on output.

       -n tracefile    Opens  tracefile	 for  recording	trace information. See
		       the set tracefile command below.

       -r	       Specifies a user	interface similar to rlogin.  In  this
		       mode,  the  escape  character  is  set to the tilde (~)
		       character, unless modified by the -e option. The	rlogin
		       escape character	is only	recognized when	it is preceded
		       by a carriage return. In	this mode, the	telnet	escape
		       character,  normally  '^]', must	still precede a	telnet
		       command.	The rlogin escape character can	also  be  fol-
		       lowed  by '.\r' or '^Z',	and, like rlogin(1), closes or
		       suspends	the connection,	respectively. This  option  is
		       an uncommitted interface	and may	change in the future.

       -x	       Turns  on  encryption of	the data stream. When this op-
		       tion is turned on, telnet will exit with	 an  error  if
		       authentication  cannot  be  negotiated or if encryption
		       cannot be turned	on.

       -X atype	       Disables	the atype type of authentication.

   telnet Commands
       The commands described in this section are available with telnet. It is
       necessary  to type only enough of each command to uniquely identify it.
       (This is	also true for arguments	to the mode, set, toggle, unset, envi-
       ron, and	display	commands.)

       auth argument ...

	   The	auth command manipulates the information sent through the TEL-
	   NET AUTHENTICATE option. Valid arguments for	the auth  command  are
	   as follows:

	   disable type	   Disables  the  specified type of authentication. To
			   obtain a list of available types, use the auth dis-
			   able	? command.

	   enable type	   Enables  the	 specified  type of authentication. To
			   obtain a list of available types, use the auth  en-
			   able	? command.

	   status	   Lists  the  current	status of the various types of
			   authentication.

       open [-l	user ] [ [!] @hop1 [@hop2 ...]@host [ port ]

	   Open	a connection to	the named host.	If no port  number  is	speci-
	   fied, telnet	will attempt to	contact	a TELNET server	at the default
	   port. The host  specification  may  be  either  a  host  name  (see
	   hosts(4),  ipnodes(4)) or an	Internet address specified in the "dot
	   notation" (see inet(	7P) or inet6( 7P)). If the host	 is  specified
	   as  @hop1@hop2@host,	 the  connection  goes	through	hosts hop1 and
	   hop2, using loose source routing to end at host. The	"@" symbol  is
	   required as a separator between the hosts specified.	If a leading !
	   is used with	IPv4, the connection follows strict source routing.

	   The -l option passes	the user as the	value of the ENVIRON  variable
	   USER	to the remote system.

       close

	   Close  any  open TELNET session and exit telnet. An EOF (in command
	   mode) will also close a session and exit.

       encrypt

	   The encrypt command manipulates the information  sent  through  the
	   TELNET ENCRYPT option.

	   Valid arguments for the encrypt command are as follows:

	   disable type	[input|outputsables  the specified type	of encryption.
				   If you omit the input and output, both  in-
				   put	and  output  are disabled. To obtain a
				   list	of available types,  use  the  encrypt
				   disable ? command.

	   enable type [input|outputnables  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 encrypt  enable  ?
				   command.

	   input		   This	is the same as the encrypt start input
				   command.

	   -input		   This	is the same as the encrypt stop	 input
				   command.

	   output		   This	 is the	same as	the encrypt start out-
				   put command.

	   -output		   This	is the same as the encrypt stop	output
				   command.

	   start [input|output]	   Attempts  to	 start encryption. If you omit
				   input and output, both input	and output are
				   enabled.  To	 obtain	 a  list  of available
				   types, use the encrypt enable ? command.

	   status		   Lists the current status of encryption.

	   stop	[input|output]	   Stops encryption. If	 you  omit  input  and
				   output,  encryption	is  on	both input and
				   output.

	   type	type		   Sets	the default type of encryption	to  be
				   used	 with  later  encrypt start or encrypt
				   stop	commands.

       quit

	   Same	as close.

       z

	   Suspend telnet. This	command	only works when	the user  is  using  a
	   shell that supports job control, such as sh(1).

       mode type

	   The	remote	host  is asked for permission to go into the requested
	   mode. If the	remote host is capable of entering that	mode, the  re-
	   quested  mode will be entered. The argument type is one of the fol-
	   lowing:

	   character		   Disable the TELNET LINEMODE option, or,  if
				   the	remote	side  does  not	understand the
				   LINEMODE option, then enter "character at a
				   time" mode.

	   line			   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.

	   isig	(-isig)		   Attempt to  enable  (disable)  the  TRAPSIG
				   mode	 of the	LINEMODE option. This requires
				   that	the LINEMODE option be enabled.

	   edit	(-edit)		   Attempt to enable (disable) the  EDIT  mode
				   of  the LINEMODE option. This requires that
				   the LINEMODE	option be enabled.

	   softtabs (-softtabs)	   Attempt to enable  (disable)	 the  SOFT_TAB
				   mode	 of the	LINEMODE option. This requires
				   that	the LINEMODE option be enabled.

	   litecho (-litecho)	   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  mode
				   command.

       status

	   Show	 the  current  status of telnet. This includes the peer	one is
	   connected to, as well as the	current	mode.

       display

	   [argument...] Display all, or some, of the set  and	toggle	values
	   (see	toggle argument...).

       ?

	   [command]  Get  help.  With no arguments, telnet prints a help sum-
	   mary. If a command is specified, telnet will	print the help	infor-
	   mation for just that	command.

       send argument...

	   Send	 one  or  more special character sequences to the remote host.
	   The following are the arguments that	can be	specified  (more  than
	   one argument	may be specified at a time):

	   escape	   Send	the current telnet escape character (initially
			   ^]).

	   synch	   Send	the TELNET SYNCH sequence. This	sequence  dis-
			   cards all previously	typed, but not yet read, input
			   on the remote system. This sequence is sent as  TCP
			   urgent  data	 and may not work if the remote	system
			   is a	4.2 BSD	system.	If it does not work,  a	 lower
			   case	"r" may	be echoed on the terminal.

	   brk or break	   Send	 the  TELNET  BRK  (Break) sequence, which may
			   have	significance to	the remote system.

	   ip		   Send	the TELNET IP  (Interrupt  Process)  sequence,
			   which  aborts  the currently	running	process	on the
			   remote system.

	   abort	   Send	the TELNET ABORT (Abort	Process) sequence.

	   ao		   Send	the TELNET AO (Abort Output)  sequence,	 which
			   flushes  all	 output	 from the remote system	to the
			   user's terminal.

	   ayt		   Send	the TELNET AYT (Are You	 There)	 sequence,  to
			   which the remote system may or may not respond.

	   ec		   Send	 the  TELNET  EC  (Erase  Character) sequence,
			   which erases	the last character entered.

	   el		   Send	the TELNET EL  (Erase  Line)  sequence,	 which
			   should  cause  the  remote system to	erase the line
			   currently being entered.

	   eof		   Send	the TELNET EOF (End Of File) sequence.

	   eor		   Send	the TELNET EOR (End Of Record) sequence.

	   ga		   Send	the TELNET GA (Go Ahead) sequence, which prob-
			   ably	has no significance for	the remote system.

	   getstatus	   If  the remote side supports	the TELNET STATUS com-
			   mand, getstatus will	send the subnegotiation	to re-
			   quest  that the server send its current option sta-
			   tus.

	   nop		   Send	the TELNET NOP (No Operation) sequence.

	   susp		   Send	the TELNET SUSP	(Suspend Process) sequence.

	   do option	   Send	the TELNET protocol option  negotiation	 indi-
	   dont	option	   cated.  Option may be the text name of the protocol
	   will	option	   option, or the number corresponding to the  option.
	   wont	option	   The	command	will be	silently ignored if the	option
			   negotiation indicated is not	valid in  the  current
			   state. If the option	is given as 'help' or '?', the
			   list	of option names	known is listed. This  command
			   is mostly useful for	unusual	debugging situations.

	   ?		   Print out help information for the send command.

       set argument [value]
       unset argument

	   Set	any  one  of a number of telnet	variables to a specific	value.
	   The special value "off" turns off the function associated with  the
	   variable. The values	of variables may be interrogated with the dis-
	   play	command. If value is omitted, the value	is taken to  be	 true,
	   or "on". If the unset form is used, the value is taken to be	false,
	   or "off." The variables that	may be specified are:

	   echo		   This	is the value  (initially  ^E)  that,  when  in
			   "line  by line" mode, toggles between local echoing
			   of entered characters for  normal  processing,  and
			   suppressing	echoing	of entered characters, for ex-
			   ample, entering a password.

	   escape	   This	is the telnet escape character (initially  ^])
			   that	enters telnet command mode when	connected to a
			   remote system.

	   interrupt	   If telnet is	in localchars mode  (see  toggle,  lo-
			   calchars)  and  the interrupt character is typed, a
			   TELNET IP sequence (see send	and ip)	is sent	to the
			   remote  host.  The  initial value for the interrupt
			   character is	taken to be the	terminal's intr	 char-
			   acter.

	   quit		   If  telnet is in localchars mode and	the quit char-
			   acter is typed, a TELNET BRK	 sequence  (see	 send,
			   brk)	 is sent to the	remote host. The initial value
			   for the quit	character is taken to  be  the	termi-
			   nal's quit character.

	   flushoutput	   If telnet is	in localchars mode and the flushoutput
			   character is	typed, a TELNET	AO sequence (see send,
			   ao)	is  sent to the	remote host. The initial value
			   for the flush character is taken to be  the	termi-
			   nal's flush character.

	   erase	   If  telnet  is  in localchars mode and operating in
			   "character at a time" mode,	then  when  the	 erase
			   character is	typed, a TELNET	EC sequence (see send,
			   ec) is sent to the remote system. The initial value
			   for	the  erase character is	taken to be the	termi-
			   nal's erase character.

	   kill		   If telnet is	in localchars mode  and	 operating  in
			   "character  at  a  time"  mode,  then when the kill
			   character is	typed, a TELNET	EL sequence (see send,
			   el) is sent to the remote system. The initial value
			   for the kill	character is taken to  be  the	termi-
			   nal's kill character.

	   eof		   If  telnet is operating in "line by line" mode, en-
			   tering the eof character as the first character  on
			   a  line  sends this character to the	remote system.
			   The initial value of	eof is taken to	be the	termi-
			   nal's eof character.

	   ayt		   If telnet is	in localchars mode, or LINEMODE	is en-
			   abled, and the status character is typed, a	TELNET
			   AYT	("Are  You There") sequence is sent to the re-
			   mote	host. (See send, ayt above.) The initial value
			   for ayt is the terminal's status character.

	   forw1	   If  telnet  is operating in LINEMODE, and the forw1
	   forw2	   or forw2 characters are typed, this causes the for-
			   warding  of partial lines to	the remote system. The
			   initial values for the forwarding  characters  come
			   from	the terminal's eol and eol2 characters.

	   lnext	   If  telnet is operating in LINEMODE or "old line by
			   line" mode, then the	lnext character	is assumed  to
			   be  the  terminal's	lnext  character.  The initial
			   value for the lnext character is taken  to  be  the
			   terminal's lnext character.

	   reprint	   If  telnet is operating in LINEMODE or "old line by
			   line" mode, then the	reprint	character  is  assumed
			   to be the terminal's	reprint	character. The initial
			   value for reprint is	taken to be the	terminal's re-
			   print character.

	   rlogin	   This	 is  the  rlogin escape	character. If set, the
			   normal telnet escape	character is  ignored,	unless
			   it  is  preceded by this character at the beginning
			   of a	line. The rlogin character, at	the  beginning
			   of  a line followed by a "."	closes the connection.
			   When	followed by a ^Z, the rlogin command  suspends
			   the telnet command. The initial state is to disable
			   the rlogin escape character.

	   start	   If the TELNET TOGGLE-FLOW-CONTROL option  has  been
			   enabled,  then  the	start character	is taken to be
			   the terminal's start	character. The	initial	 value
			   for	the  kill  character is	taken to be the	termi-
			   nal's start character.

	   stop		   If the TELNET TOGGLE-FLOW-CONTROL option  has  been
			   enabled, then the stop character is taken to	be the
			   terminal's stop character. The  initial  value  for
			   the	kill  character	 is taken to be	the terminal's
			   stop	character.

	   susp		   If telnet is	in localchars mode, or LINEMODE	is en-
			   abled, and the suspend character is typed, a	TELNET
			   SUSP	sequence (see send, susp above)	is sent	to the
			   remote  host.  The  initial	value  for the suspend
			   character is	taken to  be  the  terminal's  suspend
			   character.

	   tracefile	   This	 is  the  file	to which the output, generated
			   when	the netdata or the debug option	is TRUE,  will
			   be  written.	If tracefile is	set to "-", then trac-
			   ing information will	be written to standard	output
			   (the	default).

	   worderase	   If  telnet is operating in LINEMODE or "old line by
			   line" mode, then this character is taken to be  the
			   terminal's  worderase  character. The initial value
			   for the worderase character is taken	to be the ter-
			   minal's worderase character.

	   ?		   Displays the	legal set and unset commands.

       slc state

	   The slc (Set	Local Characters) command is used to set or change the
	   state of special characters when the	 TELNET	 LINEMODE  option  has
	   been	 enabled. Special characters are characters that get mapped to
	   TELNET commands sequences (like ip or quit) or line editing charac-
	   ters	 (like	erase and kill). By default, the local special charac-
	   ters	are exported.  The following values for	state are valid:

	   check	    Verifies the  settings  for	 the  current  special
			   characters.	The  remote  side is requested to send
			   all the  current  special  character	 settings.  If
			   there  are  any  discrepancies with the local side,
			   the local settings will switch to the  remote  val-
			   ues.

	   export	   Switches  to	 the  local  defaults  for the special
			   characters. The local default characters are	 those
			   of  the  local terminal at the time when telnet was
			   started.

	   import	   Switches 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 slc command.

       toggle argument...

	   Toggle  between  TRUE  and FALSE the	various	flags that control how
	   telnet responds to events.  More than one argument  may  be	speci-
	   fied. The state of these flags may be interrogated with the display
	   command. Valid arguments are:

	   authdebug	   Turns on debugging information for the  authentica-
			   tion	code.

	   autodecrypt	   When	 the  TELNET  ENCRYPT option is	negotiated, by
			   default the actual encryption (decryption)  of  the
			   data	 stream	 does not start	automatically. The au-
			   toencrypt (autodecrypt) command states that encryp-
			   tion	of the output (input) stream should be enabled
			   as soon as possible.

	   autologin	   If the remote side supports the TELNET  AUTHENTICA-
			   TION	 option,  telnet attempts to use it to perform
			   automatic authentication. If	the AUTHENTICATION op-
			   tion	 is  not  supported,  the user's login name is
			   propagated through the TELNET ENVIRON option.  This
			   command  is the same	as specifying the -a option on
			   the open command.

	   autoflush	   If autoflush	and localchars	are  both  TRUE,  then
			   when	 the  ao,  intr, or quit characters are	recog-
			   nized (and transformed into TELNET  sequences;  see
			   set	for  details),	telnet	refuses	to display any
			   data	on the user's terminal until the remote	system
			   acknowledges	 (using	 a  TELNET Timing Mark option)
			   that	it has processed those TELNET  sequences.  The
			   initial value for this toggle is TRUE if the	termi-
			   nal user has	not done an "stty noflsh".  Otherwise,
			   the value is	FALSE (see stty(1)).

	   autosynch	   If  autosynch  and  localchars  are both TRUE, then
			   when	either the interrupt or	 quit  characters  are
			   typed  (see	set  for descriptions of interrupt and
			   quit), the resulting	TELNET sequence	sent  is  fol-
			   lowed  by the TELNET	SYNCH sequence.	This procedure
			   should cause	the remote system  to  begin  throwing
			   away	 all  previously typed input until both	of the
			   TELNET sequences have been read and acted upon. The
			   initial value of this toggle	is FALSE.

	   binary	   Enable  or disable the TELNET BINARY	option on both
			   input and output.

	   inbinary	   Enable or disable the TELNET	BINARY option  on  in-
			   put.

	   outbinary	   Enable  or disable the TELNET BINARY	option on out-
			   put.

	   crlf		   Determines how carriage returns are	sent.  If  the
			   value  is  TRUE, then carriage returns will be sent
			   as <CR><LF>.	If the value is	FALSE,	then  carriage
			   returns  will  be  send  as	<CR><NUL>. The initial
			   value for this toggle is FALSE.

	   crmod	   Toggle <RETURN> mode. When this  mode  is  enabled,
			   most	 <RETURN>  characters received from the	remote
			   host	will be	mapped into a <RETURN> followed	 by  a
			   line	 feed. This mode does not affect those charac-
			   ters	typed by the user, only	 those	received  from
			   the	remote	host. This mode	is useful only for re-
			   mote	hosts that send	<RETURN> but never send	<LINE-
			   FEED>. The initial value for	this toggle is FALSE.

	   debug	   Toggle  socket  level  debugging (only available to
			   the super-user). The	initial	value for this	toggle
			   is FALSE.

	   encdebug	   Turns  on  debugging	information for	the encryption
			   code.

	   localchars	   If this toggle is TRUE, then	the flush,  interrupt,
			   quit, erase,	and kill characters (see set) are rec-
			   ognized locally, and	transformed  into  appropriate
			   TELNET control sequences, respectively ao, ip, brk,
			   ec, and el (see send). The initial value  for  this
			   toggle is TRUE in "line by line" mode, and FALSE in
			   "character at a time" mode. When the	 LINEMODE  op-
			   tion	 is  enabled,  the  value of localchars	is ig-
			   nored, and assumed always to	be TRUE.  If  LINEMODE
			   has	ever been enabled, then	quit is	sent as	abort,
			   and eof and suspend are sent	as eof and  susp  (see
			   send	above).

	   netdata	   Toggle the display of all network data (in hexadec-
			   imal	format). The initial value for this toggle  is
			   FALSE.

	   options	   Toggle the display of some internal TELNET protocol
			   processing (having to do with telnet	options).  The
			   initial value for this toggle is FALSE.

	   prettydump	   When	 the  netdata toggle is	enabled, if prettydump
			   is enabled, the output  from	 the  netdata  command
			   will	 be  formatted in a more user readable format.
			   Spaces are put between each character in  the  out-
			   put.	The beginning of any TELNET escape sequence is
			   preceded by an asterisk  (*)	 to  aid  in  locating
			   them.

	   skiprc	   When	 the  skiprc  toggle is	TRUE, TELNET skips the
			   reading of the .telnetrc file in  the  user's  home
			   directory  when connections are opened. The initial
			   value for this toggle is FALSE.

	   termdata	   Toggles the display of all terminal data (in	 hexa-
			   decimal  format). The initial value for this	toggle
			   is FALSE.

	   verbose_encrypt When	 the  verbose_encrypt  flag  is	 TRUE,	TELNET
			   prints  out	a  message each	time encryption	is en-
			   abled or disabled. The initial value	for this  tog-
			   gle is FALSE.

	   ?		   Display the legal toggle commands.

       environ argument...

	   The	environ	 command  is  used to manipulate variables that	may be
	   sent	through	the TELNET ENVIRON option. The initial	set  of	 vari-
	   ables  is  taken  from  the users environment. Only the DISPLAY and
	   PRINTER variables are exported by default. Valid arguments for  the
	   environ command are:

	   define variable value   Define  variable  to	have a value of	value.
				   Any variables defined by this  command  are
				   automatically  exported.  The  value	may be
				   enclosed in single  or  double  quotes,  so
				   that	tabs and spaces	may be included.

	   undefine variable	   Remove  variable  from the list of environ-
				   ment	variables.

	   export variable	   Mark	the variable to	be exported to the re-
				   mote	side.

	   unexport variable	   Mark	the variable to	not be exported	unless
				   explicitly requested	by the remote side.

	   list			   List	the current set	of  environment	 vari-
				   ables.  Those  marked  with an asterisk (*)
				   will	be sent	automatically. Other variables
				   will	be sent	only if	explicitly requested.

	   ?			   Prints out help information for the environ
				   command.

       logout

	   Sends the telnet logout option to the remote	side. This command  is
	   similar  to	a  close 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 connection. If the remote side also
	   supports the	concept	of suspending a	user's session for later reat-
	   tachment, the logout	argument indicates that	the remote side	should
	   terminate the session immediately.

       NO LOGINS: System going down in N minutes

	   The	machine	 is  in	the process of being shut down and logins have
	   been	disabled.

       On some remote systems, echo has	to be  turned  off  manually  when  in
       "line by	line" mode.

       In  "old	 line by line" mode, or	LINEMODE, the terminal's EOF character
       is only recognized (and sent to the remote system) when it is the first
       character on a line.

       The  telnet  protocol  only  uses  single  DES for session protection--
       clients request service tickets with single DES session keys.  The  KDC
       must  know  that	 host service principals that offer the	telnet service
       support single DES, which, in practice, means that such principals must
       have single DES keys in the KDC database.
