# KRB5 Enable Kerberos Version 5 Authentication code
# in libtelnet/libtelnet.a
#
-# SIMPLE_AUTH
+# SPX Enable SPX authentication code in.
+# libtelnet/libtelnet.a
+#
+# RSA_ENCPWD
+#
+# KRB4_ENCPWD
+#
#
# DES_ENCRYPTION Enable DES encryption/decryption, requires
# getting a the initial key from Kerberos. This
# works with both Kerberos Version 4 and 5.
#
+# ENV_HACK Turn on code to recognize and allow
+# interoperability with systems that have their
+# definitions for ENV_VALUE and ENV_VAR reversed.
+#
# LOCAL SYSYTEM PARAMATERS
#
# TERMCAP Define this if your system is termcap based,
#
# NO_STRING_H If you don't have <string.h>, but have <strings.h>
#
+# LOGIN_PROGRAM= Specifies the login program to use. By default,
+# it is /bin/login, or whatever is specified by
+# _PATH_LOGIN in <paths.h>
+#
# NO_LOGIN_P If /bin/login doesn't understand the "-p"
# (preserve environment) option.
#
+# LOGIN_ARGS if /bin/login understands environment variables
+# after the login name. Only used if NO_LOGIN_P
+# is defined.
+#
+# NO_LOGIN_F If /bin/login doesn't understand the "-f" option.
+# Only used if AUTHENTICATION is defined.
+#
+# LOGIN_CAP_F If /bin/login understands the "-F" option (which
+# works like "-f", but root logins are allowed).
+# Only used if NO_LOGIN_F is not defined.
+#
+# LOGIN_R This says that /bin/login understands the "-r host"
+# option. Only used if NO_LOGIN_F is defined (and
+# the system supports the TIOCSTI ioctl).
+#
+# LOGIN_HOST Only applies if LOGIN_R is defined. This
+# specifies the hostname to be passed to "login -r"
+# for successfully authenticated logins. This
+# defaults to "localhost" (don't forget to include
+# the quotes, e.g. -DLOGIN_HOST=\"localhost\").
+#
+# It can also be set to host (-DLOGIN_HOST=host)
+# to have the real hostname passed to "/bin/login -r".
+# NOTE: If you do this, then anyone that wants to
+# allow authenticated login access will have
+# to add those remote hosts to their .rhosts,
+# which sort of defeats the whole purpose of
+# authenticated login...
+#
+# NO_BSD_SETJMP For UNICOS releases prior to 7.0. Turns off
+# the inclusion of <bsdsetjmp.h>.
+#
# STREAMS If the system has streams; causes <sys/stream.h>
# to be included instead of <sys/tty.h>
#
# UTMPX System has /etc/utmpx as well as /etc/utmp.
# Use makeutx and modutx to update utmp/x and wtmp/x.
# Appropriate for SVr4 derivatives.
+#
+# HAS_CGETENT If your system has the cgetent() and cgetstr()
+# routines. This is a 4.4BSD feature, that
+# eliminates grabbing the getty gettytab.c source.
+# You need to include getent.o on the LIB_OBJ
+# line if this is defined.
+#
+# OLD_ENVIRON Support for the old environment option.
# LIB_OBJ=
# This is a list of object files that are needed but are not in
# getopt.o If you don't have getopt(3)
# herror.o If you don't have herror(3)
# gettytab.o If you can get gettytab.c from getty source.
-# getent.o If you can't get gettytab.c
-# kerberos.o If you have Kerberos Version 4
-# kerberos5.o If you have Kerberos Version 5
+# getent.o If you can't get gettytab.c (or have
+# HAS_CGETENT defined...)
# mem.o If you don't have mem*(3) routines.
# LIB_SRC=
# Name of "ranlib" program, set it to "NONE" if you don't
# have a "ranlib".

+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:
This directory contains the client code. No kernel changes are
needed to use this code.
-telnet/tmac.an:
-telnet/tmac.an.old:
-telnet/tmac.andoc:
- Macros for use in formatting the telnet/telnet.1 man page
- on non-4.3Reno systems. Just use the tmac.an, it includes
- the other two. Also, these macros work with nroff and
- ditroff, but not troff...
-
telnetd:
This directory contains the server code. If LINEMODE or KLUDGELINEMODE
are defined, then the kernel modifications listed above are needed.
but the definitions for the specific authentication
schemes is still in a state of flux.
- ENCRYPT:
+ 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,

-protocol The command is used to communicate with another host
-using the protocol. If is invoked without the argument, it
-enters command mode, indicated by its prompt In this mode, it
-accepts and executes the commands listed below. If it is invoked
-with arguments, it performs an command with those arguments.
-Options: Use an eight bit data path. This will cause an attempt
-to negotiate the BINARY option on both input and output. The
-option stops any character from being recognized as an escape
-character. Do not attempt to do automatic login to the remote
-system. Use an eight bit data path on output. This causes the
-BINARY option to be negotiated on output. Disable the type of
-authentication. Attempt automatic login. Currently, this sends
-the user name via the USER variable of the ENVIRON option if sup-
-ported by the remote system. The name used is that of the
-current user as returned by if it agrees with the current user
-ID, otherwise it is the name associated with the user ID. The
-flag disables the reading of the users (See the command below.)
-Sets the initial value of the toggle to Sets the initial telnet
-escape character to If is ommitted, then there will be no escape
-character. If Kerberos authentication is being used, the option
-requests that obtain tickets for the remote host in realm instead
-of the remote host's realm as determined by When connecting to
-the remote system, if the remote system understands the ENVIRON
-option, then will be sent to the remote system as the value for
-the variable USER. This option implies the option. This option
-may also be used with the command. Opens for recording trace
-information. See the command below. Use a user interface simi-
-lar to In this mode, the escape character is set to the tilde
-(``~'') character, unless modified by the flag. Turn on encryp-
-tion of the data stream, if possible. Indicates the official
-name, an alias, or the Internet address of a remote host. Indi-
-cates a port number (address of an application) or name. If a
-number is not specified, the default port is used. Port names
-are mapped to port numbers via the /etc/services file. Normally
-when a port number is specified, will not send out any initial
-option negotiation. If the port number/name is preceded by a
-minus sign, then the initial option negotiation will be sent.
-When in mode, a line of the form ``~.'' disconnects from the
-remote host, where ``~'' is the escape character. Similarly, the
-line ``~^Z'' will suspend the session. The line ``~^]'' will
-escape to the normal escape prompt. Once a connection has been
-opened, will attempt to enable the option. If this fails, then
-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 is enabled, character processing is done on the local sys-
-tem, 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 sys-
-tem, so that they can take effect on the local system. In char-
-acter 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 character (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 option is enabled, or if the toggle is TRUE (the default for
-old line by line; see below), the user's and characters are
-trapped locally, and sent as protocol sequences to the remote
-side. If has ever been enabled, then the user's and are also
-sent as protocol sequences, and is sent as a instead of There are
-options (see and below) which cause this action to flush subse-
-quent output to the terminal (until the remote host acknowledges
-the sequence) and flush previous terminal input (in the case of
-and While connected to a remote host, command mode may be entered
-by typing the escape character (initially ^ ). When in command
-mode, the normal terminal editing conventions are available. The
-following commands are available. Only enough of each command to
-uniquely identify it need be typed (this is also true for most of
-the arguments to the commands). The command is used to manipu-

-as the command. List the current status of encryption. The com-
-mand is used to manipulate the the variables that my be sent
-through the option. The initial set of variables is taken from
-the users environment, with only the and variables being exported
-by default. The variable is also exported if the or options are
-used.
-Valid arguments for the environ command are: Define the variable
-to have a value of Any variables defined by this command are
-automatically exported. The may be enclosed in single or double
-quotes so that tabs and spaces may be included. Remove from the
-list of environment variables. Mark the variable to be exported
-to the remote side. Mark the variable to not be exported unless
-explicitly asked for by the remote side. 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 command. Send
-the option to the remote side. This is similar to doing a com-
-mand, however if the remote side does not support the option,
-then nothing will happen. If, however, the remote side does sup-
-port the option, then this command should cause the remote side
-to close the connection. In addition, if the remote side sup-
-ports the concept of suspending a users session for later re-
-attachement, the option indicates that the session should be ter-
-minated immediately. is one of several options, depending on the
-state of the 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. Disable
-the option, or, if the remote side does not understand the
-option, then enter character at a time mode. Enable the option,
-or, if the remote side does not understand the option, then
-attempt to enter old-line-by-line mode. Attempt to enable (dis-
-able) the mode of the option. This requires that the option be
-enabled. Attempt to enable (disable) the mode of the option.
-This requires that the option be enabled. Attempt to enable
-(disable) the mode of the option. This requires that the option
-be enabled. Attempt to enable (disable) the mode of the option.
-This requires that the option be enabled. Prints out help infor-
-mation for the command. Open a connection to the named host. If
-no port number is specified, will attempt to contact a server at
-the default port. The host specification may be either a host
-name (see or an Internet address specified in the dot notation
-(see The option may be used to specify the user name to be passed
-to the remote system via the option. When connecting to a non-
-standard port, omits any automatic initiation of options. When
-the port number is preceded by a minus sign, the initial option
-negotiation is done. After establishing a connection, if the
-variable is not enabled (see the command below), the file in the
-users home directory is opened. Lines beginning with a # are
-comment lines. Blank lines are ignored. Lines that begin
-without whitespace are the start of a machine entry. The first
-thing on the line is the name of the machine that is being con-
-nected to. The rest of the line, and successive lines that begin
-with whitespace are assumed to be commands and are processed as
-if they had been typed in manually to the command prompt. The
-special machine name is used to specify commands that should be
-executed for all machines. There may be more than one entry for
-a machine; all matches will the specified machine name will be
-executed. Close any open session and exit An end of file (in
-command mode) will also close a session and exit. Sends one or
-more special character sequences to the remote host. The follow-
-ing are the arguments which may be specified (more than one argu-
-ment may be specified at a time): Sends the (ABORT processes)
-sequence. Sends the (Abort Output) sequence, which should cause
-the remote system to flush all output the remote system the
-user's terminal. Sends the (Are You There) sequence, to which
-the remote system may or may not choose to respond. Sends the
-(Break) sequence, which may have significance to the remote sys-
-tem. Sends the (Erase Character) sequence, which should cause
-the remote system to erase the last character entered. Sends the
-(Erase Line) sequence, which should cause the remote system to
-erase the line currently being entered. Sends the (End Of File)
-sequence. Sends the (End of Record) sequence. Sends the current
-escape character (initially ^). Sends the (Go Ahead) sequence,
-which likely has no significance to the remote system. If the
-remote side supports the command, will send the subnegotiation to
-request that the server send its current option status. Sends
-the (Interrupt Process) sequence, which should cause the remote
-system to abort the currently running process. Sends the (No
-OPeration) sequence. Sends the (SUSPend process) sequence.
-Sends the 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 4.2 BSD system -- if it doesn't work, a lower
-case r may be echoed on the terminal). Prints out help informa-
-tion for the command. The command will set any one of a number
-of variables to a specific value or to TRUE. The special value
-turns off the function associated with the variable, this is
-equivalent to using the command. The command will disable or set
-to FALSE any of the specified functions. The values of variables
-may be interrogated with the command. The variables which may be
-set or unset, but not toggled, are listed here. In addition, any
-of the variables for the command may be explicitly set or unset
-using the and commands. If is in mode, or is enabled, and the
-character is typed, a sequence (see above) is sent to the remote
-host. The initial value for the ayt character is taken to be the
-terminal's character. 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 echo-
-ing of entered characters (for entering, say, a password). If is
-operating in 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 charac-
-ter is taken to be the terminal's character. If is in mode (see
-below), if is operating in character at a time mode, then when
-this character is typed, a sequence (see above) is sent to the
-remote system. The initial value for the erase character is
-taken to be the terminal's character. This is the escape charac-
-ter (initially ^[) which causes entry into command mode (when
-connected to a remote system). If is in mode (see below) and the
-character is typed, a sequence (see above) is sent to the remote
-host. The initial value for the flush character is taken to be
-the terminal's character. If is operating in these are the char-
-acters that, when typed, cause partial lines to be forwarded to
-the remote system. The initial value for the forw1 and forw2
-characters are taken from the terminal's and characters. If is
-in mode (see below) and the character is typed, a sequence (see
-above) is sent to the remote host. The initial value for the
-interrupt character is taken to be the terminal's character. If
-is in mode (see below), if is operating in character at a time
-mode, then when this character is typed, a sequence (see above)
-is sent to the remote system. The initial value for the kill
-character is taken to be the terminal's character. If is operat-
-ing in or old line by line mode, then this character is taken to
-be the terminal's character. The initial value for the lnext
-character is taken to be the terminal's character. If is in mode
-(see below) and the character is typed, a sequence (see above) is
-sent to the remote host. The initial value for the quit charac-
-ter is taken to be the terminal's character. If is operating in
-or old line by line mode, then this character is taken to be the
-terminal's character. The initial value for the reprint charac-
-ter is taken to be the terminal's character. This is the rlogin
-escape character. If set, the normal character will be 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
-``.'' will close the connection; when followed by a ``^Z'' it
-will suspend the command. The initial state is to have the
-escape character disabled. If the option has been enabled, then
-this character is taken to be the terminal's character. The ini-
-tial value for the kill character is taken to be the terminal's
-character. If the option has been enabled, then this character
-is taken to be the terminal's character. The initial value for
-the kill character is taken to be the terminal's character. If
-is in mode, or is enabled, and the character is typed, a sequence
-(see above) is sent to the remote host. The initial value for
-the suspend character is taken to be the terminal's character.
-This is the file to which the output, caused by or tracing being
-TRUE, will be written. If it is set to then tracing information
-will be written to standard output (the default). If is operat-
-ing in or old line by line mode, then this character is taken to
-be the terminal's character. The initial value for the worderase
-character is taken to be the terminal's character. Displays the
-legal commands. The command (Set Local Characters) is used to
-set or change the state of the the special characters when the
-option has been enabled. Special characters are characters that
-get mapped to commands sequences (like or or line editing charac-
-ters (like and By default, the local special characters are
-exported. Switch to the local defaults for the special charac-
-ters. The local default characters are those of the local termi-
-nal at the time when was started. Switch to the remote defaults
-for the special characters. The remote default characters are
-those of the remote system at the time when the connection was
-established. Verify the current settings for the current special
-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. Prints out help information for the command. Show the

-well as the current mode. Toggle (between TRUE and FALSE) vari-
-ous flags that control how responds to events. These flags may
-be set explicitly to TRUE or FALSE using the and commands listed
-above. More than one argument may be specified. The state of
-these flags may be interrogated with the command. Valid
-arguments are: Turn on debugging information for the authentica-
-tion code. If and are both TRUE, then when the or characters are
-recognized (and transformed into sequences; see above for
-details), refuses to display any data on the user's terminal
-until the remote system acknowledges (via a option) that it has
-processed those sequences. The initial value for this toggle is
-TRUE if the terminal user had not done an "stty noflsh", other-
-wise FALSE (see When the option is negotiated, by default the
-actual encryption (decryption) of the data stream does not
-automatically start. The command states that encryption of the
-output (input) stream should be enabled as soon as possible. If
-the option is supported by the remote side, then will attempt to
-use it to perform automatic authentication. If the option is not
-supported, then the users login name will be propagated via the

+ The t\bte\bel\bln\bne\bet\bt command is used to communicate with another host using the
+ TELNET protocol. If t\bte\bel\bln\bne\bet\bt is invoked without the _\bh_\bo_\bs_\bt argument, it en-
+ ters command mode, indicated by its prompt (t\bte\bel\bln\bne\bet\bt>\b>). In this mode, it
+ accepts and executes the commands listed below. If it is invoked with
+ arguments, it performs an o\bop\bpe\ben\bn command with those arguments.
+
+ Options:
+
+ -\b-8\b8 Specifies an 8-bit data path. This causes an attempt to negoti-
+ ate the TELNET BINARY option on both input and output.
+
+ -\b-E\bE Stops any character from being recognized as an escape character.
+
+ -\b-F\bF If Kerberos V5 authentication is being used, the -\b-F\bF option allows
+ the local credentials to be forwarded to the remote system, in-
+ cluding any credentials that have already been forwarded into the
+ local environment.
+
+ -\b-K\bK Specifies no automatic login to the remote system.
+
+ -\b-L\bL Specifies an 8-bit data path on output. This causes the BINARY
+ option to be negotiated on output.
+
+ -\b-S\bS _\bt_\bo_\bs Sets the IP type-of-service (TOS) option for the telnet connec-
+ tion to the value _\bt_\bo_\bs_\b, which can be a numeric TOS value or, on
+ systems that support it, a symbolic TOS name found in the
+ /etc/iptos file.
+
+ -\b-X\bX _\ba_\bt_\by_\bp_\be
+ Disables the _\ba_\bt_\by_\bp_\be type of authentication.
+
+ -\b-a\ba Attempt automatic login. Currently, this sends the user name via
+ the USER variable of the ENVIRON option if supported by the re-
+ mote system. The name used is that of the current user as re-
+ turned by getlogin(2) if it agrees with the current user ID, oth-
+ erwise it is the name associated with the user ID.
+
+ -\b-c\bc Disables the reading of the user's _\b._\bt_\be_\bl_\bn_\be_\bt_\br_\bc file. (See the
+ t\bto\bog\bgg\bgl\ble\be s\bsk\bki\bip\bpr\brc\bc command on this man page.)
+
+ -\b-d\bd Sets the initial value of the d\bde\beb\bbu\bug\bg toggle to TRUE
+
+ -\b-e\be _\be_\bs_\bc_\ba_\bp_\be _\bc_\bh_\ba_\br
+ Sets the initial t\bte\bel\bln\bne\bet\bt t\bte\bel\bln\bne\bet\bt escape character to _\be_\bs_\bc_\ba_\bp_\be _\bc_\bh_\ba_\br_\b.
+ If _\be_\bs_\bc_\ba_\bp_\be _\bc_\bh_\ba_\br is omitted, then there will be no escape charac-
+ ter.
+
+ -\b-f\bf If Kerberos V5 authentication is being used, the -\b-f\bf option allows
+ the local credentials to be forwarded to the remote system.
+
+ -\b-k\bk _\br_\be_\ba_\bl_\bm
+ If Kerberos authentication is being used, the -\b-k\bk option requests
+ that telnet obtain tickets for the remote host in realm realm in-
+ stead of the remote host's realm, as determined by
+
+ krb_realmofhost(3).
+
+ -\b-l\bl _\bu_\bs_\be_\br
+ When connecting to the remote system, if the remote system under-
+ stands the ENVIRON option, then _\bu_\bs_\be_\br will be sent to the remote
+ system as the value for the variable USER. This option implies
+ the -\b-a\ba option. This option may also be used with the o\bop\bpe\ben\bn com-
+ mand.
+
+ -\b-n\bn _\bt_\br_\ba_\bc_\be_\bf_\bi_\bl_\be
+ Opens _\bt_\br_\ba_\bc_\be_\bf_\bi_\bl_\be for recording trace information. See the s\bse\bet\bt
+ t\btr\bra\bac\bce\bef\bfi\bil\ble\be command below.
+
+ -\b-r\br 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.
+
+ -\b-x\bx Turns on encryption of the data stream if possible. This option
+ is not available outside of the United States and Canada.
+
+ _\bh_\bo_\bs_\bt Indicates the official name, an alias, or the Internet address of
+ a remote host.
+
+ _\bp_\bo_\br_\bt Indicates a port number (address of an application). If a number
+ is not specified, the default t\bte\bel\bln\bne\bet\bt 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, t\bte\bel\bln\bne\bet\bt will attempt to enable the
+ TELNET LINEMODE option. If this fails, then t\bte\bel\bln\bne\bet\bt 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 l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs toggle is TRUE
+ (the default for ``old line by line``; see below), the user's q\bqu\bui\bit\bt, i\bin\bnt\btr\br,
+ and f\bfl\blu\bus\bsh\bh characters are trapped locally, and sent as TELNET protocol se-
+ quences to the remote side. If LINEMODE has ever been enabled, then the
+ user's s\bsu\bus\bsp\bp and e\beo\bof\bf are also sent as TELNET protocol sequences, and q\bqu\bui\bit\bt
+ is sent as a TELNET ABORT instead of BREAK There are options (see t\bto\bog\bgg\bgl\ble\be
+ a\bau\but\bto\bof\bfl\blu\bus\bsh\bh and t\bto\bog\bgg\bgl\ble\be a\bau\but\bto\bos\bsy\byn\bnc\bch\bh below) which cause this action to flush
+ subsequent output to the terminal (until the remote host acknowledges the
+ TELNET sequence) and flush previous terminal input (in the case of q\bqu\bui\bit\bt
+ and i\bin\bnt\btr\br).
+
+ While connected to a remote host, t\bte\bel\bln\bne\bet\bt command mode may be entered by
+ typing the t\bte\bel\bln\bne\bet\bt ``escape character'' (initially ``^]''). When in com-
+ mand mode, the normal terminal editing conventions are available.
+
+ The following t\bte\bel\bln\bne\bet\bt commands are available. Only enough of each command
+ to uniquely identify it need be typed (this is also true for arguments to
+ the m\bmo\bod\bde\be, s\bse\bet\bt, t\bto\bog\bgg\bgl\ble\be, u\bun\bns\bse\bet\bt, s\bsl\blc\bc, e\ben\bnv\bvi\bir\bro\bon\bn, and d\bdi\bis\bsp\bpl\bla\bay\by commands).

+ 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:
+
+ d\bdi\bis\bsa\bab\bbl\ble\be _\bt_\by_\bp_\be [\b[i\bin\bnp\bpu\but\bt|\b|o\bou\but\btp\bpu\but\bt]\b]

+
+ i\bin\bnp\bpu\but\bt This is the same as the e\ben\bnc\bcr\bry\byp\bpt\bt s\bst\bta\bar\brt\bt i\bin\bnp\bpu\but\bt com-

+
+ s\bst\bta\bar\brt\bt [\b[i\bin\bnp\bpu\but\bt|\b|o\bou\but\btp\bpu\but\bt]\b]
+ Attempts to start encryption. If you omit i\bin\bnp\bpu\but\bt
+ and o\bou\but\btp\bpu\but\bt,\b, both input and output are enabled.
+ To obtain a list of available types, use the

+
+ t\bty\byp\bpe\be _\bt_\by_\bp_\be Sets the default type of encryption to be used
+ with later e\ben\bnc\bcr\bry\byp\bpt\bt s\bst\bta\bar\brt\bt or e\ben\bnc\bcr\bry\byp\bpt\bt s\bst\bto\bop\bp com-
+ mands.
+
+ e\ben\bnv\bvi\bir\bro\bon\bn _\ba_\br_\bg_\bu_\bm_\be_\bn_\bt_\bs_\b._\b._\b.
+ The e\ben\bnv\bvi\bir\bro\bon\bn 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 -\b-a\ba or -\b-l\bl
+ options are used.
+ Valid arguments for the e\ben\bnv\bvi\bir\bro\bon\bn command are:
+
+ d\bde\bef\bfi\bin\bne\be _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be _\bv_\ba_\bl_\bu_\be
+ Define the variable _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be to have a value of
+ _\bv_\ba_\bl_\bu_\be_\b. Any variables defined by this command are
+ automatically exported. The _\bv_\ba_\bl_\bu_\be may be enclosed
+ in single or double quotes so that tabs and spaces
+ may be included.
+
+ u\bun\bnd\bde\bef\bfi\bin\bne\be _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be
+ Remove _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be from the list of environment vari-
+ ables.
+
+ e\bex\bxp\bpo\bor\brt\bt _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be
+ Mark the variable _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be to be exported to the
+ remote side.
+
+ u\bun\bne\bex\bxp\bpo\bor\brt\bt _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be
+ Mark the variable _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be to not be exported un-
+ less explicitly asked for by the remote side.
+
+ l\bli\bis\bst\bt List the current set of environment variables.
+ Those marked with a *\b* will be sent automatically,
+ other variables will only be sent if explicitly
+ requested.
+
+ ?\b? Prints out help information for the e\ben\bnv\bvi\bir\bro\bon\bn com-
+ mand.
+
+ l\blo\bog\bgo\bou\but\bt Sends the TELNET LOGOUT option to the remote side. This com-
+ mand is similar to a c\bcl\blo\bos\bse\be 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.
+
+ m\bmo\bod\bde\be _\bt_\by_\bp_\be _\bT_\by_\bp_\be 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 en-
+ tering that mode, the requested mode will be entered.
+
+ c\bch\bha\bar\bra\bac\bct\bte\ber\br Disable the TELNET LINEMODE option, or, if the
+ remote side does not understand the LINEMODE op-
+
+ tion, then enter ``character at a time`` mode.
+
+ l\bli\bin\bne\be Enable the TELNET LINEMODE option, or, if the
+ remote side does not understand the LINEMODE op-
+ tion, then attempt to enter ``old-line-by-line``
+ mode.
+
+ i\bis\bsi\big\bg (-\b-i\bis\bsi\big\bg) Attempt to enable (disable) the TRAPSIG mode of
+ the LINEMODE option. This requires that the
+ LINEMODE option be enabled.
+
+ e\bed\bdi\bit\bt (-\b-e\bed\bdi\bit\bt) Attempt to enable (disable) the EDIT mode of the
+ LINEMODE option. This requires that the
+ LINEMODE option be enabled.
+
+ s\bso\bof\bft\btt\bta\bab\bbs\bs (-\b-s\bso\bof\bft\btt\bta\bab\bbs\bs)
+ Attempt to enable (disable) the SOFT_TAB mode of
+ the LINEMODE option. This requires that the
+ LINEMODE option be enabled.
+
+ l\bli\bit\bte\bec\bch\bho\bo (-\b-l\bli\bit\bte\bec\bch\bho\bo)
+ Attempt to enable (disable) the LIT_ECHO mode of
+ the LINEMODE option. This requires that the
+ LINEMODE option be enabled.
+
+ ?\b? Prints out help information for the m\bmo\bod\bde\be com-
+ mand.
+
+ o\bop\bpe\ben\bn _\bh_\bo_\bs_\bt [[-\b-l\bl] _\bu_\bs_\be_\br][-\b-_\bp_\bo_\br_\bt]
+ Open a connection to the named host. If no port number is
+ specified, t\bte\bel\bln\bne\bet\bt 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 [-\b-l\bl] 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,
+ t\bte\bel\bln\bne\bet\bt omits any automatic initiation of TELNET options. When
+ the port number is preceded by a minus sign, the initial op-
+ tion negotiation is done. After establishing a connection,
+ the file _\b._\bt_\be_\bl_\bn_\be_\bt_\br_\bc 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 as-
+ sumed to be t\bte\bel\bln\bne\bet\bt commands and are processed as if they had
+ been typed in manually to the t\bte\bel\bln\bne\bet\bt command prompt.
+
+ q\bqu\bui\bit\bt Close any open TELNET session and exit t\bte\bel\bln\bne\bet\bt. An end of file
+ (in command mode) will also close a session and exit.
+
+ s\bse\ben\bnd\bd _\ba_\br_\bg_\bu_\bm_\be_\bn_\bt_\bs
+ 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):
+
+ a\bab\bbo\bor\brt\bt Sends the TELNET ABORT (Abort processes) sequence.
+
+ a\bao\bo Sends the TELNET AO (Abort Output) sequence, which
+ should cause the remote system to flush all output
+ _\bf_\br_\bo_\bm the remote system _\bt_\bo the user's terminal.
+
+ a\bay\byt\bt Sends the TELNET AYT (Are You There) sequence, to
+ which the remote system may or may not choose to re-
+
+
+ spond.
+
+ b\bbr\brk\bk Sends the TELNET BRK (Break) sequence, which may have
+ significance to the remote system.
+
+ e\bec\bc Sends the TELNET EC (Erase Character) sequence, which
+ should cause the remote system to erase the last char-
+ acter entered.
+
+ e\bel\bl Sends the TELNET EL (Erase Line) sequence, which
+ should cause the remote system to erase the line cur-
+ rently being entered.
+
+ e\beo\bof\bf Sends the TELNET EOF (End Of File) sequence.
+
+ e\beo\bor\br Sends the TELNET EOR (End of Record) sequence.
+
+ e\bes\bsc\bca\bap\bpe\be Sends the current t\bte\bel\bln\bne\bet\bt escape character (initially
+ ``^'').
+
+ g\bga\ba Sends the TELNET GA (Go Ahead) sequence, which likely
+ has no significance to the remote system.
+
+ g\bge\bet\bts\bst\bta\bat\btu\bus\bs
+ If the remote side supports the TELNET STATUS command,
+ g\bge\bet\bts\bst\bta\bat\btu\bus\bs will send the subnegotiation to request that
+ the server send its current option status.
+
+ i\bip\bp Sends the TELNET IP (Interrupt Process) sequence,
+ which should cause the remote system to abort the cur-
+ rently running process.
+
+ n\bno\bop\bp Sends the TELNET NOP (No OPeration) sequence.
+
+ s\bsu\bus\bsp\bp Sends the TELNET SUSP (SUSPend process) sequence.
+
+ s\bsy\byn\bnc\bch\bh 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 ur-
+ gent 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).
+
+ d\bdo\bo _\bc_\bm_\bd
+
+ d\bdo\bon\bnt\bt _\bc_\bm_\bd
+
+ w\bwi\bil\bll\bl _\bc_\bm_\bd
+
+ w\bwo\bon\bnt\bt _\bc_\bm_\bd
+ Sends the TELNET DO _\bc_\bm_\bd sequence. _\bC_\bm_\bd can be either a
+ decimal number between 0 and 255, or a symbolic name
+ for a specific TELNET command. _\bC_\bm_\bd can also be either
+ h\bhe\bel\blp\bp or ?\b? to print out help information, including a
+ list of known symbolic names.
+
+ ?\b? Prints out help information for the s\bse\ben\bnd\bd command.
+
+ s\bse\bet\bt _\ba_\br_\bg_\bu_\bm_\be_\bn_\bt _\bv_\ba_\bl_\bu_\be
+
+ u\bun\bns\bse\bet\bt _\ba_\br_\bg_\bu_\bm_\be_\bn_\bt _\bv_\ba_\bl_\bu_\be
+ The s\bse\bet\bt command will set any one of a number of t\bte\bel\bln\bne\bet\bt vari-
+ ables to a specific value or to TRUE. The special value o\bof\bff\bf
+ turns off the function associated with the variable, this is
+ equivalent to using the u\bun\bns\bse\bet\bt command. The u\bun\bns\bse\bet\bt command will
+ disable or set to FALSE any of the specified functions. The
+ values of variables may be interrogated with the d\bdi\bis\bsp\bpl\bla\bay\by 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 t\bto\bog\bgg\bgl\ble\be command may be explicitly set or unset using the
+ s\bse\bet\bt and u\bun\bns\bse\bet\bt commands.
+
+ a\bay\byt\bt If TELNET is in localchars mode, or LINEMODE is en-
+ abled, and the status character is typed, a TELNET AYT
+ sequence (see s\bse\ben\bnd\bd a\bay\byt\bt preceding) is sent to the re-
+ mote host. The initial value for the "Are You There"
+ character is the terminal's status character.
+
+ e\bec\bch\bho\bo 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 en-
+ tering, say, a password).
+
+ e\beo\bof\bf If t\bte\bel\bln\bne\bet\bt 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 e\beo\bof\bf char-
+ acter.
+
+ e\ber\bra\bas\bse\be If t\bte\bel\bln\bne\bet\bt is in l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs mode (see t\bto\bog\bgg\bgl\ble\be l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs
+ below), a\ban\bnd\bd if t\bte\bel\bln\bne\bet\bt is operating in ``character at a
+ time'' mode, then when this character is typed, a
+ TELNET EC sequence (see s\bse\ben\bnd\bd e\bec\bc above) is sent to the
+ remote system. The initial value for the erase char-
+ acter is taken to be the terminal's e\ber\bra\bas\bse\be character.
+
+ e\bes\bsc\bca\bap\bpe\be This is the t\bte\bel\bln\bne\bet\bt escape character (initially ``^['')
+ which causes entry into t\bte\bel\bln\bne\bet\bt command mode (when con-
+ nected to a remote system).
+
+ f\bfl\blu\bus\bsh\bho\bou\but\btp\bpu\but\bt
+ If t\bte\bel\bln\bne\bet\bt is in l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs mode (see t\bto\bog\bgg\bgl\ble\be l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs
+ below) and the f\bfl\blu\bus\bsh\bho\bou\but\btp\bpu\but\bt character is typed, a
+ TELNET AO sequence (see s\bse\ben\bnd\bd a\bao\bo above) is sent to the
+ remote host. The initial value for the flush charac-
+ ter is taken to be the terminal's f\bfl\blu\bus\bsh\bh character.
+
+ f\bfo\bor\brw\bw1\b1
+
+ f\bfo\bor\brw\bw2\b2 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.
+
+ i\bin\bnt\bte\ber\brr\bru\bup\bpt\bt
+ If t\bte\bel\bln\bne\bet\bt is in l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs mode (see t\bto\bog\bgg\bgl\ble\be l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs
+ below) and the i\bin\bnt\bte\ber\brr\bru\bup\bpt\bt character is typed, a TELNET
+ IP sequence (see s\bse\ben\bnd\bd i\bip\bp above) is sent to the remote
+ host. The initial value for the interrupt character
+ is taken to be the terminal's i\bin\bnt\btr\br character.
+
+ k\bki\bil\bll\bl If t\bte\bel\bln\bne\bet\bt is in l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs mode (see t\bto\bog\bgg\bgl\ble\be l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs
+ below), a\ban\bnd\bd if t\bte\bel\bln\bne\bet\bt is operating in ``character at a
+ time'' mode, then when this character is typed, a
+ TELNET EL sequence (see s\bse\ben\bnd\bd e\bel\bl above) is sent to the
+ remote system. The initial value for the kill charac-
+ ter is taken to be the terminal's k\bki\bil\bll\bl character.
+
+ l\bln\bne\bex\bxt\bt If t\bte\bel\bln\bne\bet\bt is operating in LINEMODE or ``old line by
+ line`` mode, then this character is taken to be the
+ terminal's l\bln\bne\bex\bxt\bt character. The initial value for the
+ lnext character is taken to be the terminal's l\bln\bne\bex\bxt\bt
+ character.
+
+ q\bqu\bui\bit\bt If t\bte\bel\bln\bne\bet\bt is in l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs mode (see t\bto\bog\bgg\bgl\ble\be l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs
+ below) and the q\bqu\bui\bit\bt character is typed, a TELNET BRK
+ sequence (see s\bse\ben\bnd\bd b\bbr\brk\bk above) is sent to the remote
+ host. The initial value for the quit character is
+ taken to be the terminal's q\bqu\bui\bit\bt character.
+
+ r\bre\bep\bpr\bri\bin\bnt\bt
+ If t\bte\bel\bln\bne\bet\bt is operating in LINEMODE or ``old line by
+ line`` mode, then this character is taken to be the

+ the reprint character is taken to be the terminal's
+ r\bre\bep\bpr\bri\bin\bnt\bt character.
+
+ r\brl\blo\bog\bgi\bin\bn 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.
+
+ s\bst\bta\bar\brt\bt If the TELNET TOGGLE-FLOW-CONTROL option has been en-
+ abled, then this character is taken to be the termi-
+ nal's s\bst\bta\bar\brt\bt character. The initial value for the kill
+ character is taken to be the terminal's s\bst\bta\bar\brt\bt charac-
+ ter.
+
+ s\bst\bto\bop\bp If the TELNET TOGGLE-FLOW-CONTROL option has been en-
+ abled, then this character is taken to be the termi-
+ nal's s\bst\bto\bop\bp character. The initial value for the kill
+ character is taken to be the terminal's s\bst\bto\bop\bp charac-
+ ter.
+
+ s\bsu\bus\bsp\bp If t\bte\bel\bln\bne\bet\bt is in l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs mode, or LINEMODE is en-
+ abled, and the s\bsu\bus\bsp\bpe\ben\bnd\bd character is typed, a TELNET
+ SUSP sequence (see s\bse\ben\bnd\bd s\bsu\bus\bsp\bp above) is sent to the re-
+ mote host. The initial value for the suspend charac-
+ ter is taken to be the terminal's s\bsu\bus\bsp\bpe\ben\bnd\bd character.
+
+ t\btr\bra\bac\bce\bef\bfi\bil\ble\be
+ This is the file to which the output, caused by
+ n\bne\bet\btd\bda\bat\bta\ba or o\bop\bpt\bti\bio\bon\bn tracing being TRUE, will be written.
+ If it is set to ``-\b-'', then tracing information will
+ be written to standard output (the default).
+
+ w\bwo\bor\brd\bde\ber\bra\bas\bse\be
+ If t\bte\bel\bln\bne\bet\bt is operating in LINEMODE or ``old line by
+ line`` mode, then this character is taken to be the
+ terminal's w\bwo\bor\brd\bde\ber\bra\bas\bse\be character. The initial value for
+ the worderase character is taken to be the terminal's
+ w\bwo\bor\brd\bde\ber\bra\bas\bse\be character.
+
+ ?\b? Displays the legal s\bse\bet\bt (u\bun\bns\bse\bet\bt) commands.
+
+ s\bsl\blc\bc _\bs_\bt_\ba_\bt_\be The s\bsl\blc\bc 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
+ i\bip\bp or q\bqu\bui\bit\bt) or line editing characters (like e\ber\bra\bas\bse\be and k\bki\bil\bll\bl).
+
+
+ By default, the local special characters are exported.
+
+ c\bch\bhe\bec\bck\bk 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.
+
+ e\bex\bxp\bpo\bor\brt\bt Switch to the local defaults for the special char-
+ acters. The local default characters are those of
+ the local terminal at the time when t\bte\bel\bln\bne\bet\bt was
+ started.
+
+ i\bim\bmp\bpo\bor\brt\bt 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.
+
+ ?\b? Prints out help information for the s\bsl\blc\bc command.
+
+ s\bst\bta\bat\btu\bus\bs Show the current status of t\bte\bel\bln\bne\bet\bt. This includes the peer one

+
+ t\bto\bog\bgg\bgl\ble\be _\ba_\br_\bg_\bu_\bm_\be_\bn_\bt_\bs _\b._\b._\b.
+ Toggle (between TRUE and FALSE) various flags that control how
+ t\bte\bel\bln\bne\bet\bt responds to events. These flags may be set explicitly
+ to TRUE or FALSE using the s\bse\bet\bt and u\bun\bns\bse\bet\bt commands listed
+ above. More than one argument may be specified. The state of
+ these flags may be interrogated with the d\bdi\bis\bsp\bpl\bla\bay\by command.

+ when the a\bao\bo, or q\bqu\bui\bit\bt characters are recognized
+ (and transformed into TELNET sequences; see s\bse\bet\bt
+ above for details), t\bte\bel\bln\bne\bet\bt 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 se-
+ quences. The initial value for this toggle is
+ TRUE if the terminal user had not done an "stty
+ noflsh", otherwise FALSE (see stty(1)).
+
+ a\bau\but\bto\bod\bde\bec\bcr\bry\byp\bpt\bt 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.
+
+ a\bau\but\bto\bol\blo\bog\bgi\bin\bn 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 us-
+ er's login name are propagated through the
+ TELNET ENVIRON option. This command is the same
+ as specifying _\ba option on the o\bop\bpe\ben\bn command.
+
+ a\bau\but\bto\bos\bsy\byn\bnc\bch\bh If a\bau\but\bto\bos\bsy\byn\bnc\bch\bh and l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs are both TRUE, then
+ when either the i\bin\bnt\btr\br or q\bqu\bui\bit\bt characters is typed
+ (see s\bse\bet\bt above for descriptions of the i\bin\bnt\btr\br and
+ q\bqu\bui\bit\bt characters), the resulting TELNET sequence
+ sent is followed by the TELNET SYNCH sequence.
+ This procedure s\bsh\bho\bou\bul\bld\bd 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.

+ i\bin\bnb\bbi\bin\bna\bar\bry\by Enable or disable the TELNET BINARY option on
+ input.
+
+ o\bou\but\btb\bbi\bin\bna\bar\bry\by Enable or disable the TELNET BINARY option on
+ output.
+
+ c\bcr\brl\blf\bf 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.
+
+ c\bcr\brm\bmo\bod\bd Toggle carriage return mode. When this mode is
+ enabled, most carriage return characters re-
+ ceived 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 nev-
+ er line feed. The initial value for this toggle
+ is FALSE.
+
+ d\bde\beb\bbu\bug\bg Toggles socket level debugging (useful only to
+ the s\bsu\bup\bpe\ber\br u\bus\bse\ber\br). The initial value for this tog-
+ gle is FALSE.
+
+ e\ben\bnc\bcd\bde\beb\bbu\bug\bg Turns on debugging information for the encryp-
+ tion code.
+
+ l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs If this is TRUE, then the f\bfl\blu\bus\bsh\bh, i\bin\bnt\bte\ber\brr\bru\bup\bpt\bt,
+ q\bqu\bui\bit\bt, e\ber\bra\bas\bse\be, and k\bki\bil\bll\bl characters (see s\bse\bet\bt above)
+ are recognized locally, and transformed into
+ (hopefully) appropriate TELNET control sequences
+ (respectively a\bao\bo, i\bip\bp, b\bbr\brk\bk, e\bec\bc, and e\bel\bl; see s\bse\ben\bnd\bd
+ 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 l\blo\boc\bca\bal\blc\bch\bha\bar\brs\bs is
+ ignored, and assumed to always be TRUE. If
+ LINEMODE has ever been enabled, then q\bqu\bui\bit\bt is
+ sent as a\bab\bbo\bor\brt\bt, and e\beo\bof\bf a\ban\bnd\bd are sent as e\beo\bof\bf a\ban\bnd\bd
+ s\bsu\bus\bsp\bp, see s\bse\ben\bnd\bd above).
+
+ n\bne\bet\btd\bda\bat\bta\ba Toggles the display of all network data (in hex-
+ adecimal format). The initial value for this
+ toggle is FALSE.
+
+ o\bop\bpt\bti\bio\bon\bns\bs Toggles the display of some internal t\bte\bel\bln\bne\bet\bt pro-
+ tocol processing (having to do with TELNET op-
+ tions). The initial value for this toggle is
+ FALSE.
+
+ p\bpr\bre\bet\btt\bty\byd\bdu\bum\bmp\bp When the n\bne\bet\btd\bda\bat\bta\ba toggle is enabled, if
+ p\bpr\bre\bet\btt\bty\byd\bdu\bum\bmp\bp is enabled the output from the
+ n\bne\bet\btd\bda\bat\bta\ba 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.
+
+ s\bsk\bki\bip\bpr\brc\bc When the skiprc toggle is TRUE, TELNET skips the
+ reading of the _\b._\bt_\be_\bl_\bn_\be_\bt_\br_\bc file in the users home
+ directory when connections are opened. The ini-
+ tial value for this toggle is FALSE.
+
+ t\bte\ber\brm\bmd\bda\bat\bta\ba Toggles the display of all terminal data (in

+ When the v\bve\ber\brb\bbo\bos\bse\be_\b_e\ben\bnc\bcr\bry\byp\bpt\bt toggle is TRUE, TELNET
+ prints out a message each time encryption is en-

-NAME
- telnetd - DARPA TELNET protocol server
-
-SYNOPSIS
- /etc/telnetd [-debug [_\bp_\bo_\br_\bt]] [-l] [-D options] [-D report]
- [-D exercise] [-D netdata] [-D ptydata]
-
-DESCRIPTION
- _\bT_\be_\bl_\bn_\be_\bt_\bd is a server which supports the DARPA standard TELNET
- virtual terminal protocol. _\bT_\be_\bl_\bn_\be_\bt_\bd is invoked by the inter-
- net server (see _\bi_\bn_\be_\bt_\bd(8)), normally for requests to connect
- to the TELNET port as indicated by the /_\be_\bt_\bc/_\bs_\be_\br_\bv_\bi_\bc_\be_\bs file
- (see _\bs_\be_\br_\bv_\bi_\bc_\be_\bs(5)). If the -debug may be used, to start up
- telnetd manually, instead of through _\bi_\bn_\be_\bt_\bd(8). If started
- up this way, _\bp_\bo_\br_\bt may be specified to run _\bt_\be_\bl_\bn_\be_\bt_\bd on an
- alternate TCP port number.
-
- The -D option may be used for debugging purposes. This
- allows _\bt_\be_\bl_\bn_\be_\bt to print out debugging information to the con-
- nection, allowing the user to see what telnetd is doing.
- There are several modifiers: options prints information
- about the negotiation of TELNET options, report prints the
- options information, plus some additional information about
- what processing is going on, netdata displays the data
- stream received by _\bt_\be_\bl_\bn_\be_\bt_\bd, ptydata displays data written to
- the pty, and exercise has not been implemented yet.
-
- _\bT_\be_\bl_\bn_\be_\bt_\bd operates by allocating a pseudo-terminal device (see
- _\bp_\bt_\by(4)) for a client, then creating a login process which
- has the slave side of the pseudo-terminal as stdin, stdout,
- and stderr. _\bT_\be_\bl_\bn_\be_\bt_\bd manipulates the master side of the
- pseudo-terminal, implementing the TELNET protocol and pass-
- ing characters between the remote client and the login pro-
- cess.
-
- When a TELNET session is started up, _\bt_\be_\bl_\bn_\be_\bt_\bd sends TELNET
- options to the client side indicating a willingness to do

-BUGS
- Some TELNET commands are only partially implemented.
-
- Because of bugs in the original 4.2 BSD _\bt_\be_\bl_\bn_\be_\bt(1), _\bt_\be_\bl_\bn_\be_\bt_\bd
- performs some dubious protocol exchanges to try to discover
- if the remote client is, in fact, a 4.2 BSD _\bt_\be_\bl_\bn_\be_\bt(1).
-
- _\bB_\bi_\bn_\ba_\br_\by _\bm_\bo_\bd_\be has no common interpretation except between
- similar operating systems (Unix in this case).
-
- The terminal type name received from the remote client is
- converted to lower case.
-
- _\bT_\be_\bl_\bn_\be_\bt_\bd never sends TELNET _\bg_\bo _\ba_\bh_\be_\ba_\bd commands.

+ The t\bte\bel\bln\bne\bet\btd\bd command is a server which supports the DARPA standard TELNET
+ virtual terminal protocol. T\bTe\bel\bln\bne\bet\btd\bd is normally invoked by the internet
+ server (see inetd(8)) for requests to connect to the TELNET port as in-
+ dicated by the _\b/_\be_\bt_\bc_\b/_\bs_\be_\br_\bv_\bi_\bc_\be_\bs file (see services(5)). The -\b-d\bde\beb\bbu\bug\bg option
+ may be used to start up t\bte\bel\bln\bne\bet\btd\bd manually, instead of through inetd(8).
+ If started up this way, _\bp_\bo_\br_\bt may be specified to run t\bte\bel\bln\bne\bet\btd\bd on an alter-
+ nate TCP port number.
+
+ The t\bte\bel\bln\bne\bet\btd\bd command accepts the following options:
+
+ -\b-a\ba _\ba_\bu_\bt_\bh_\bm_\bo_\bd_\be This option may be used for specifying what mode should be
+ used for authentication. Note that this option is only use-
+ ful if t\bte\bel\bln\bne\bet\btd\bd has been compiled with support for the
+ AUTHENTICATION option. There are several valid values for
+ _\ba_\bu_\bt_\bh_\bm_\bo_\bd_\be_\b:
+
+ debug Turns on authentication debugging code.
+
+ user Only allow connections when the remote user can pro-
+ vide valid authentication information to identify the
+ remote user, and is allowed access to the specified
+ account without providing a password.
+
+ valid Only allow connections when the remote user can pro-
+ vide valid authentication information to identify the
+ remote user. The login(1) command will provide any
+ additional user verification needed if the remote us-
+ er is not allowed automatic access to the specified
+ account.
+
+ other Only allow connections that supply some authentica-
+ tion information. This option is currently not sup-
+ ported by any of the existing authentication mecha-
+ nisms, and is thus the same as specifying -\b-a\ba v\bva\bal\bli\bid\bd.
+
+ none This is the default state. Authentication informa-
+ tion is not required. If no or insufficient authen-
+ tication information is provided, then the login(1)
+ program will provide the necessary user verification.
+
+ off This disables the authentication code. All user ver-
+ ification will happen through the login(1) program.
+
+ -\b-B\bB Specifies bftp server mode. In this mode, t\bte\bel\bln\bne\bet\btd\bd causes
+ login to start a bftp(1) session rather than the user's nor-
+ mal shell. In bftp daemon mode normal logins are not sup-
+ ported, and it must be used on a port other than the normal
+ TELNET port.
+
+ -\b-D\bD _\bd_\be_\bb_\bu_\bg_\bm_\bo_\bd_\be
+ This option may be used for debugging purposes. This allows
+ t\bte\bel\bln\bne\bet\btd\bd to print out debugging information to the connec-
+ tion, allowing the user to see what t\bte\bel\bln\bne\bet\btd\bd is doing. There
+
+ are several possible values for _\bd_\be_\bb_\bu_\bg_\bm_\bo_\bd_\be_\b:
+
+ o\bop\bpt\bti\bio\bon\bns\bs Prints information about the negotiation of TELNET
+ options.
+
+ r\bre\bep\bpo\bor\brt\bt Prints the o\bop\bpt\bti\bio\bon\bns\bs information, plus some addi-
+ tional information about what processing is going
+ on.
+
+ n\bne\bet\btd\bda\bat\bta\ba Displays the data stream received by t\bte\bel\bln\bne\bet\btd\bd.\b.
+
+ p\bpt\bty\byd\bda\bat\bta\ba Displays data written to the pty.
+
+ e\bex\bxe\ber\brc\bci\bis\bse\be Has not been implemented yet.
+
+ -\b-d\bde\beb\bbu\bug\bg Enables debugging on each socket created by t\bte\bel\bln\bne\bet\btd\bd (see
+ SO_DEBUG in socket(2)).
+
+ -\b-e\bed\bde\beb\bbu\bug\bg If t\bte\bel\bln\bne\bet\btd\bd has been compiled with support for data encryp-
+ tion, then the -\b-e\bed\bde\beb\bbu\bug\bg option may be used to enable encryp-
+ tion debugging code.
+
+ -\b-h\bh Disables the printing of host-specific information before
+ login has been completed.
+
+ -\b-I\bI _\bi_\bn_\bi_\bt_\bi_\bd This option is only applicable to UNICOS systems prior to
+ 7.0. It specifies the ID from _\b/_\be_\bt_\bc_\b/_\bi_\bn_\bi_\bt_\bt_\ba_\bb to use when init
+ starts login sessions. The default ID is fe.
+
+ -\b-k\bk This option is only useful if t\bte\bel\bln\bne\bet\btd\bd has been compiled with
+ both linemode and kludge linemode support. If the -\b-k\bk option
+ is specified, then if the remote client does not support the
+ LINEMODE option, then t\bte\bel\bln\bne\bet\btd\bd will operate in character at a
+ time mode. It will still support kludge linemode, but will
+ only go into kludge linemode if the remote client requests
+ it. (This is done by by the client sending DONT SUPPRESS-
+ GO-AHEAD and DONT ECHO.) The -\b-k\bk option is most useful when
+ there are remote clients that do not support kludge
+ linemode, but pass the heuristic (if they respond with WILL
+ TIMING-MARK in response to a DO TIMING-MARK) for kludge
+ linemode support.
+
+ -\b-l\bl Specifies line mode. Tries to force clients to use line-
+ at-a-time mode. If the LINEMODE option is not supported, it
+ will go into kludge linemode.
+
+ -\b-n\bn Disable TCP keep-alives. Normally t\bte\bel\bln\bne\bet\btd\bd enables the TCP
+ keep-alive mechanism to probe connections that have been
+ idle for some period of time to determine if the client is
+ still there, so that idle connections from machines that
+ have crashed or can no longer be reached may be cleaned up.
+
+ -\b-r\br _\bl_\bo_\bw_\bp_\bt_\by_\b-_\bh_\bi_\bg_\bh_\bp_\bt_\by
+ This option is only enabled when t\bte\bel\bln\bne\bet\btd\bd is compiled for
+ UNICOS. It specifies an inclusive range of pseudo-terminal
+ devices to use. If the system has sysconf variable
+ _SC_CRAY_NPTY configured, the default pty search range is 0
+ to _SC_CRAY_NPTY; otherwise, the default range is 0 to 128.
+ Either _\bl_\bo_\bw_\bp_\bt_\by or _\bh_\bi_\bg_\bh_\bp_\bt_\by may be omitted to allow changing
+ either end of the search range. If _\bl_\bo_\bw_\bp_\bt_\by is omitted, the -
+ character is still required so that t\bte\bel\bln\bne\bet\btd\bd can differenti-
+ ate _\bh_\bi_\bg_\bh_\bp_\bt_\by from _\bl_\bo_\bw_\bp_\bt_\by.
+
+ -\b-s\bs This option is only enabled if t\bte\bel\bln\bne\bet\btd\bd is compiled with sup-
+ port for SecurID cards. It causes the -\b-s\bs option to be
+ passed on to login(1), and thus is only useful if login(1)
+ supports the -\b-s\bs flag to indicate that only SecurID validated
+ logins are allowed, and is usually useful for controlling
+ remote logins from outside of a firewall.
+
+ -\b-S\bS _\bt_\bo_\bs
+
+ -\b-u\bu _\bl_\be_\bn This option is used to specify the size of the field in the
+ utmp structure that holds the remote host name. If the re-
+ solved host name is longer than _\bl_\be_\bn, the dotted decimal val-
+ ue will be used instead. This allows hosts with very long
+ host names that overflow this field to still be uniquely
+ identified. Specifying -\b-u\bu0\b0 indicates that only dotted deci-
+ mal addresses should be put into the _\bu_\bt_\bm_\bp file.
+
+ -\b-U\bU This option causes t\bte\bel\bln\bne\bet\btd\bd to refuse connections from ad-
+ dresses that cannot be mapped back into a symbolic name via
+ the gethostbyaddr(3) routine.
+
+ -\b-X\bX _\ba_\bu_\bt_\bh_\bt_\by_\bp_\be This option is only valid if t\bte\bel\bln\bne\bet\btd\bd has been built with
+ support for the authentication option. It disables the use
+ of _\ba_\bu_\bt_\bh_\bt_\by_\bp_\be authentication, and can be used to temporarily
+ disable a specific authentication type without having to re-
+ compile t\bte\bel\bln\bne\bet\btd\bd.
+
+ T\bTe\bel\bln\bne\bet\btd\bd operates by allocating a pseudo-terminal device (see pty(4)) for
+ a client, then creating a login process which has the slave side of the
+ pseudo-terminal as stdin, stdout and stderr. T\bTe\bel\bln\bne\bet\btd\bd manipulates the mas-
+ ter side of the pseudo-terminal, implementing the TELNET protocol and
+ passing characters between the remote client and the login process.
+
+ When a TELNET session is started up, t\bte\bel\bln\bne\bet\btd\bd sends TELNET options to the
+ client side indicating a willingness to do the following TELNET options,
+ which are described in more detail below:
+
+ DO AUTHENTICATION
+ WILL ENCRYPT
+ DO TERMINAL TYPE
+ DO TSPEED
+ DO XDISPLOC
+ DO NEW-ENVIRON
+ DO ENVIRON
+ WILL SUPPRESS GO AHEAD
+ DO ECHO
+ DO LINEMODE
+ DO NAWS
+ WILL STATUS
+ DO LFLOW
+ DO TIMING-MARK
+
+ The pseudo-terminal allocated to the client is configured to operate in
+ cooked mode, and with XTABS and CRMOD enabled (see tty(4)).
+
+ T\bTe\bel\bln\bne\bet\btd\bd has support for enabling locally the following TELNET options:
+
+ WILL ECHO When the LINEMODE option is enabled, a WILL ECHO or
+ WONT ECHO will be sent to the client to indicate the
+ current state of terminal echoing. When terminal echo
+ is not desired, a WILL ECHO is sent to indicate that
+ telnetd will take care of echoing any data that needs
+ to be echoed to the terminal, and then nothing is
+ echoed. When terminal echo is desired, a WONT ECHO is
+ sent to indicate that telnetd will not be doing any
+ terminal echoing, so the client should do any terminal
+ echoing that is needed.
+
+ WILL BINARY Indicates that the client is willing to send a 8 bits
+ of data, rather than the normal 7 bits of the Network
+ Virtual Terminal.
+
+ WILL SGA Indicates that it will not be sending IAC GA, go
+ ahead, commands.
+
+ WILL STATUS Indicates a willingness to send the client, upon re-
+ quest, of the current status of all TELNET options.
+
+ WILL TIMING-MARK Whenever a DO TIMING-MARK command is received, it is
+ always responded to with a WILL TIMING-MARK
+
+ WILL LOGOUT When a DO LOGOUT is received, a WILL LOGOUT is sent in
+ response, and the TELNET session is shut down.
+
+ WILL ENCRYPT Only sent if t\bte\bel\bln\bne\bet\btd\bd is compiled with support for data
+ encryption, and indicates a willingness to decrypt the
+ data stream.
+
+ T\bTe\bel\bln\bne\bet\btd\bd has support for enabling remotely the following TELNET options:
+
+ DO BINARY Sent to indicate that telnetd is willing to receive an
+ 8 bit data stream.
+
+ DO LFLOW Requests that the client handle flow control charac-
+ ters remotely.
+
+ DO ECHO This is not really supported, but is sent to identify
+ a 4.2BSD telnet(1) client, which will improperly re-
+ spond with WILL ECHO. If a WILL ECHO is received, a
+ DONT ECHO will be sent in response.
+
+ DO TERMINAL-TYPE Indicates a desire to be able to request the name of
+ the type of terminal that is attached to the client
+ side of the connection.
+
+ DO SGA Indicates that it does not need to receive IAC GA, the
+ go ahead command.
+
+ DO NAWS Requests that the client inform the server when the
+ window (display) size changes.
+
+ DO TERMINAL-SPEED Indicates a desire to be able to request information
+ about the speed of the serial line to which the client
+ is attached.
+
+ DO XDISPLOC Indicates a desire to be able to request the name of
+ the X windows display that is associated with the tel-
+ net client.
+
+ DO NEW-ENVIRON Indicates a desire to be able to request environment
+ variable information, as described in RFC 1572.
+
+ DO ENVIRON Indicates a desire to be able to request environment
+ variable information, as described in RFC 1408.
+
+ DO LINEMODE Only sent if t\bte\bel\bln\bne\bet\btd\bd is compiled with support for
+ linemode, and requests that the client do line by line
+ processing.
+
+ DO TIMING-MARK Only sent if t\bte\bel\bln\bne\bet\btd\bd is compiled with support for both
+ linemode and kludge linemode, and the client responded
+ with WONT LINEMODE. If the client responds with WILL
+ TM, the it is assumed that the client supports kludge
+ linemode. Note that the [-\b-k\bk] option can be used to
+
+ disable this.
+
+ DO AUTHENTICATION Only sent if t\bte\bel\bln\bne\bet\btd\bd is compiled with support for au-
+ thentication, and indicates a willingness to receive
+ authentication information for automatic login.
+
+ DO ENCRYPT Only sent if t\bte\bel\bln\bne\bet\btd\bd is compiled with support for data
+ encryption, and indicates a willingness to decrypt the
+ data stream.

file (see
-.IR services (5)).
-If the \fB\-debug\fP may be used, to start up \fBtelnetd\fP
+.Xr services 5 ) .
+The
+.Fl debug
+option may be used to start up
+.Nm telnetd
manually, instead of through
-.IR inetd (8).
-If started up this way, \fIport\fP may be specified to
-run \fItelnetd\fP on an alternate TCP port number.
-.PP
-The \fB\-D\fP option may be used for debugging purposes.
-This allows \fItelnet\fR to print out debugging information
-to the connection, allowing the user to see what telnetd
+.Xr inetd 8 .
+If started up this way,
+.Ar port
+may be specified to run
+.Nm telnetd
+on an alternate
+.Tn TCP
+port number.
+.Pp
+The
+.Nm telnetd
+command accepts the following options:
+.Bl -tag -width "-a authmode"
+.It Fl a Ar authmode
+This option may be used for specifying what mode should
+be used for authentication.
+Note that this option is only useful if
+.Nm telnetd
+has been compiled with support for the
+.Dv AUTHENTICATION
+option.
+There are several valid values for
+.Ar authmode:
+.Bl -tag -width debug
+.It debug
+Turns on authentication debugging code.
+.It user
+Only allow connections when the remote user
+can provide valid authentication information
+to identify the remote user,
+and is allowed access to the specified account
+without providing a password.
+.It valid
+Only allow connections when the remote user
+can provide valid authentication information
+to identify the remote user.
+The
+.Xr login 1
+command will provide any additional user verification
+needed if the remote user is not allowed automatic
+access to the specified account.
+.It other
+Only allow connections that supply some authentication information.
+This option is currently not supported
+by any of the existing authentication mechanisms,
+and is thus the same as specifying
+.Fl a
+.Cm valid .
+.It none
+This is the default state.
+Authentication information is not required.
+If no or insufficient authentication information
+is provided, then the
+.Xr login 1
+program will provide the necessary user
+verification.
+.It off
+This disables the authentication code.
+All user verification will happen through the
+.Xr login 1
+program.
+.El
+.It Fl B
+Specifies bftp server mode. In this mode,
+.Nm telnetd
+causes login to start a
+.Xr bftp 1
+session rather than the user's
+normal shell. In bftp daemon mode normal
+logins are not supported, and it must be used
+on a port other than the normal
+.Tn TELNET
+port.
+.It Fl D Ar debugmode
+This option may be used for debugging purposes.
+This allows
+.Nm telnetd
+to print out debugging information
+to the connection, allowing the user to see what
+.Nm telnetd
is doing.
-There are several modifiers:
-\fBoptions\fR prints information about the negotiation
-of \fBTELNET\fR options,
-\fBreport\fR prints the \fBoptions\fR information, plus
-some additional information about what processing is going on,
-\fBnetdata\fP displays the data stream received by \fItelnetd\fP,
-\fBptydata\fP displays data written to the pty, and
-\fBexercise\fR has not been implemented yet.
-.PP
-.I Telnetd
+There are several possible values for
+.Ar debugmode:
+.Bl -tag -width exercise
+.It Cm options
+Prints information about the negotiation of
+.Tn TELNET
+options.
+.It Cm report
+Prints the
+.Cm options
+information, plus some additional information
+about what processing is going on.
+.It Cm netdata
+Displays the data stream received by
+.Nm telnetd.
+.It Cm ptydata
+Displays data written to the pty.
+.It Cm exercise
+Has not been implemented yet.
+.El
+.It Fl debug
+Enables debugging on each socket created by
+.Nm telnetd
+(see
+.Dv SO_DEBUG
+in
+.Xr socket 2 ) .
+.It Fl edebug
+If
+.Nm telnetd
+has been compiled with support for data encryption, then the
+.Fl edebug
+option may be used to enable encryption debugging code.
+.It Fl h
+Disables the printing of host-specific information before
+login has been completed.
+.It Fl I Ar initid
+This option is only applicable to
+.Tn UNICOS
+systems prior to 7.0.
+It specifies the
+.Dv ID
+from
+.Pa /etc/inittab
+to use when init starts login sessions. The default
+.Dv ID
+is
+.Dv fe.
+.It Fl k
+This option is only useful if
+.Nm telnetd
+has been compiled with both linemode and kludge linemode
+support. If the
+.Fl k
+option is specified, then if the remote client does not
+support the
+.Dv LINEMODE
+option, then
+.Nm telnetd
+will operate in character at a time mode.
+It will still support kludge linemode, but will only
+go into kludge linemode if the remote client requests
+it.
+(This is done by by the client sending
+.Dv DONT SUPPRESS-GO-AHEAD
+and
+.Dv DONT ECHO . )
+The
+.Fl k
+option is most useful when there are remote clients
+that do not support kludge linemode, but pass the heuristic
+(if they respond with
+.Dv WILL TIMING-MARK
+in response to a
+.Dv DO TIMING-MARK)
+for kludge linemode support.
+.It Fl l
+Specifies line mode. Tries to force clients to use line-
+at-a-time mode.
+If the
+.Dv LINEMODE
+option is not supported, it will go
+into kludge linemode.
+.It Fl n
+Disable
+.Dv TCP
+keep-alives. Normally
+.Nm telnetd
+enables the
+.Tn TCP
+keep-alive mechanism to probe connections that
+have been idle for some period of time to determine
+if the client is still there, so that idle connections
+from machines that have crashed or can no longer
+be reached may be cleaned up.
+.It Fl r Ar lowpty-highpty
+This option is only enabled when
+.Nm telnetd
+is compiled for
+.Dv UNICOS.
+It specifies an inclusive range of pseudo-terminal devices to
+use. If the system has sysconf variable
+.Dv _SC_CRAY_NPTY
+configured, the default pty search range is 0 to
+.Dv _SC_CRAY_NPTY;
+otherwise, the default range is 0 to 128. Either
+.Ar lowpty
+or
+.Ar highpty
+may be omitted to allow changing
+either end of the search range. If
+.Ar lowpty
+is omitted, the - character is still required so that
+.Nm telnetd
+can differentiate
+.Ar highpty
+from
+.Ar lowpty .
+.It Fl s
+This option is only enabled if
+.Nm telnetd
+is compiled with support for
+.Tn SecurID
+cards.
+It causes the
+.Fl s
+option to be passed on to
+.Xr login 1 ,
+and thus is only useful if
+.Xr login 1
+supports the
+.Fl s
+flag to indicate that only
+.Tn SecurID
+validated logins are allowed, and is
+usually useful for controlling remote logins
+from outside of a firewall.
+.It Fl S Ar tos
+.It Fl u Ar len
+This option is used to specify the size of the field
+in the
+.Dv utmp
+structure that holds the remote host name.
+If the resolved host name is longer than
+.Ar len ,
+the dotted decimal value will be used instead.
+This allows hosts with very long host names that
+overflow this field to still be uniquely identified.
+Specifying
+.Fl u0
+indicates that only dotted decimal addresses
+should be put into the
+.Pa utmp
+file.
+.It Fl U
+This option causes
+.Nm telnetd
+to refuse connections from addresses that
+cannot be mapped back into a symbolic name
+via the
+.Xr gethostbyaddr 3
+routine.
+.It Fl X Ar authtype
+This option is only valid if
+.Nm telnetd
+has been built with support for the authentication option.
+It disables the use of
+.Ar authtype
+authentication, and
+can be used to temporarily disable
+a specific authentication type without having to recompile
+.Nm telnetd .
+.El
+.Pp
+.Nm Telnetd
operates by allocating a pseudo-terminal device (see
-.IR pty (4))
+.Xr pty 4 )
for a client, then creating a login process which has
the slave side of the pseudo-terminal as
-.BR stdin ,
-.BR stdout ,
+.Dv stdin ,
+.Dv stdout
and
-.BR stderr .
-.I Telnetd
+.Dv stderr .
+.Nm Telnetd
manipulates the master side of the pseudo-terminal,
implementing the
-.B TELNET
+.Tn TELNET
protocol and passing characters
between the remote client and the login process.
