-.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
-option, then
-.Ar user
-will be sent to the remote system as the value for the variable USER.
-This option implies the
-.Fl a
-option.
-This option may also be used with the
-.Ic open
-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
-.Dv LINEMODE
-option is enabled, or 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
-.Tn TELNET
-sequence) and flush previous terminal input
-(in the case of
-.Ic quit
-and
-.Ic intr ) .
-.Pp
-While connected to a remote host,
-.Nm telnet
-command mode may be entered by typing the
-.Nm telnet
-\*(Lqescape character\*(Rq (initially \*(Lq^]\*(Rq).
-When in command mode, the normal terminal editing conventions are available.
-.Pp
-The following
-.Nm telnet
-commands are available.
-Only enough of each command to uniquely identify it need be typed
-(this is also true for arguments to the
-.Ic mode ,
-.Ic set ,
-.Ic toggle ,
-.Ic unset ,
-.Ic slc ,
-.Ic environ ,
-and
-.Ic display
-commands).
-.Pp
-.Bl -tag -width "mode type"
-.It Ic auth Ar argument ...
-The auth command manipulates the information sent through the
-.Dv TELNET AUTHENTICATE
-option. Valid arguments for the
-auth command are as follows:
-.Bl -tag -width "disable type"
-.It Ic disable Ar type
-Disables the specified type of authentication. To
-obtain a list of available types, use the
-.Ic auth disable ?\&
-command.
-.It Ic enable Ar type
-Enables the specified type of authentication. To
-obtain a list of available types, use the
-.Ic auth enable ?\&
-command.
-.It Ic status
-Lists the current status of the various types of
-authentication.
-.El
-.It Ic close
-Close a
-.Tn TELNET
-session and return to command mode.
-.It Ic display Ar argument ...
-Displays all, or some, of the
-.Ic set
-and
-.Ic toggle
-values (see below).
-.It Ic encrypt Ar argument ...
-The encrypt command manipulates the information sent through the
-.Dv TELNET ENCRYPT
-option.
-.Pp
-Note: Because of export controls, the
-.Dv TELNET ENCRYPT
-option is not supported outside of the United States and Canada.
-.Pp
-Valid arguments for the encrypt command are as follows:
-.Bl -tag -width Ar
-.It Ic disable Ar type Xo
-.Op Cm input | output
-.Xc
-Disables the specified type of encryption. If you
-omit the input and output, both input and output
-are disabled. To obtain a list of available
-types, use the
-.Ic encrypt disable ?\&
-command.
-.It Ic enable Ar type Xo
-.Op Cm input | output
-.Xc
-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
-.Ic encrypt enable ?\&
-command.
-.It Ic input
-This is the same as the
-.Ic encrypt start input
-command.
-.It Ic -input
-This is the same as the
-.Ic encrypt stop input
-command.
-.It Ic output
-This is the same as the
-.Ic encrypt start output
-command.
-.It Ic -output
-This is the same as the
-.Ic encrypt stop output
-command.
-.It Ic start Op Cm input | output

-Lists the current status of encryption.
-.It Ic stop Op Cm input | output
-Stops encryption. If you omit input and output,
-encryption is on both input and output.
-.It Ic type Ar type
-Sets the default type of encryption to be used
-with later
-.Ic encrypt start
-or
-.Ic encrypt stop
-commands.
-.El
-.It Ic environ Ar arguments ...
-The
-.Ic environ
-command is used to manipulate the
-the variables that my be sent through the
-.Dv TELNET ENVIRON
-option.
-The initial set of variables is taken from the users
-environment, with only the
-.Ev DISPLAY
-and
-.Ev PRINTER
-variables being exported by default.
-The
-.Ev USER
-variable is also exported if the
-.Fl a
-or
-.Fl l
-options are used.
-.Pp
-Valid arguments for the
-.Ic environ
-command are:
-.Bl -tag -width Fl
-.It Ic define Ar variable value
-Define the variable
-.Ar variable
-to have a value of
-.Ar value .
-Any variables defined by this command are automatically exported.
-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-

-
- 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

- 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
- any data on the user's terminal until the remote
- system acknowledges (via a TELNET TIMING MARK
- option) that it has processed those TELNET
- sequences. The initial value for this toggle is
- TRUE if the terminal user had not done an "stty
- noflsh", otherwise FALSE (see stty(1)).
-
- aauuttooddeeccrryypptt When the TELNET ENCRYPT option is negotiated, by
- default the actual encryption (decryption) of
- the data stream does not start automatically.
- The autoencrypt (autodecrypt) command states
- that encryption of the output (input) stream
- should be enabled as soon as possible.
-
- Note: Because of export controls, the TELNET
- ENCRYPT option is not supported outside the
- United States and Canada.
-
- aauuttoollooggiinn If the remote side supports the TELNET
- AUTHENTICATION option TELNET attempts to use it
- to perform automatic authentication. If the
- AUTHENTICATION option is not supported, the
- user's login name are propagated through the
- TELNET ENVIRON option. This command is the same
- as specifying _a option on the ooppeenn command.
-
- aauuttoossyynncchh If aauuttoossyynncchh and llooccaallcchhaarrss are both TRUE, then
- when either the iinnttrr or qquuiitt characters is typed
- (see sseett above for descriptions of the iinnttrr and
- qquuiitt characters), the resulting TELNET sequence
- sent is followed by the TELNET SYNCH sequence.
- This procedure sshhoouulldd 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.
-
- bbiinnaarryy Enable or disable the TELNET BINARY option on
- both input and output.
-
- iinnbbiinnaarryy Enable or disable the TELNET BINARY option on
- input.
-
- oouuttbbiinnaarryy Enable or disable the TELNET BINARY option on
- output.
-
- ccrrllff If this is TRUE, then carriage returns will be
- sent as <CR><LF>. If this is FALSE, then car-
- riage returns will be send as <CR><NUL>. The
- initial value for this toggle is FALSE.
-
- ccrrmmoodd 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 FALSE.
-
- ddeebbuugg Toggles socket level debugging (useful only to
- the ssuuppeerr uusseerr). The initial value for this
- toggle is FALSE.
-
- eennccddeebbuugg Turns on debugging information for the encryp-
- tion code.
-
- llooccaallcchhaarrss If this is TRUE, then the fflluusshh, iinntteerrrruupptt,
- qquuiitt, eerraassee, and kkiillll characters (see sseett above)
- are recognized locally, and transformed into
- (hopefully) appropriate TELNET control sequences
- (respectively aaoo, iipp, bbrrkk, eecc, and eell; see sseenndd
- above). The initial value for this toggle is
- TRUE in ``old line by line'' mode, and FALSE in
- ``character at a time'' mode. When the LINEMODE
- option is enabled, the value of llooccaallcchhaarrss is
- ignored, and assumed to always be TRUE. If
- LINEMODE has ever been enabled, then qquuiitt is
- sent as aabboorrtt, and eeooff and ssuussppeenndd are sent as
- eeooff and ssuusspp, see sseenndd above).
-
- nneettddaattaa Toggles the display of all network data (in
- hexadecimal format). The initial value for this
- toggle is FALSE.
-
- ooppttiioonnss Toggles the display of some internal tteellnneett pro-
- tocol processing (having to do with TELNET
- options). The initial value for this toggle is
- FALSE.
-
- pprreettttyydduummpp When the nneettddaattaa toggle is enabled, if
- pprreettttyydduummpp is enabled the output from the
- nneettddaattaa command will be formatted in a more user
- readable format. Spaces are put between each
- character in the output, and the beginning of
- any TELNET escape sequence is preceded by a '*'
- to aid in locating them.
-
- sskkiipprrcc When the skiprc toggle is TRUE, TELNET skips the
- reading of the _._t_e_l_n_e_t_r_c file in the users home
- directory when connections are opened. The ini-
- tial value for this toggle is FALSE.
-
- tteerrmmddaattaa Toggles the display of all terminal data (in
- hexadecimal format). The initial value for this
- toggle is FALSE.
-
- vveerrbboossee__eennccrryypptt
- When the vveerrbboossee__eennccrryypptt toggle is TRUE, TELNET
- prints out a message each time encryption is
- enabled or disabled. The initial value for this
- toggle is FALSE. Note: Because of export con-
- trols, data encryption is not supported outside
- of the United States and Canada.
-
- ?? Displays the legal ttooggggllee commands.
-
- zz Suspend tteellnneett. This command only works when the user is
- using the csh(1).
-
- !! [_c_o_m_m_a_n_d]
- Execute a single command in a subshell on the local system.
- If ccoommmmaanndd is omitted, then an interactive subshell is
- invoked.
-
- ?? [_c_o_m_m_a_n_d]
- Get help. With no arguments, tteellnneett prints a help summary.
- If a command is specified, tteellnneett will print the help informa-
- tion for just that command.
-
-EENNVVIIRROONNMMEENNTT
- TTeellnneett uses at least the HOME, SHELL, DISPLAY, and TERM environment vari-
- ables. Other environment variables may be propagated to the other side
- via the TELNET ENVIRON option.
-
-FFIILLEESS
- ~/.telnetrc user customized telnet startup values
-
-HHIISSTTOORRYY
- The TTeellnneett command appeared in 4.2BSD.
-
-NNOOTTEESS
- On some remote systems, echo has to be turned off manually when in ``old
- line by line'' mode.
-
- In ``old line by line'' mode or LINEMODE the terminal's eeooff character is
- only recognized (and sent to the remote system) when it is the first
- character on a line.
