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 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. + + --cc Disables the reading of the user's _._t_e_l_n_e_t_r_c file.

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 Turns on encryption of the data stream if possible. This is cur- + rently the default and when it fails a warning is issued. + + _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 se- + quences 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 acknowledges 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.

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.

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 op- + tion 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 as- + sumed 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 re- + + spond. + + 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 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). + + 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 en- + abled, and the status character is typed, a TELNET AYT + sequence (see sseenndd aayytt preceding) is sent to the re- + mote 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 en- + tering, 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 en- + abled, 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 en- + abled, 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 en- + abled, and the ssuussppeenndd character is typed, a TELNET + SUSP sequence (see sseenndd ssuusspp above) is sent to the re- + mote host. The initial value for the suspend charac- + ter 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.

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 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)). + + 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 us- + er'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.

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 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. + + ddeebbuugg Toggles socket level debugging (useful only to + the ssuuppeerr uusseerr). The initial value for this tog- + gle 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 --ddeebbuugg option + may be used to start up tteellnneettdd manually, instead of through inetd(8). + If started up this way, _p_o_r_t may be specified to run tteellnneettdd on an alter- + nate TCP port number. + + The tteellnneettdd command accepts the following options: + + --aa _a_u_t_h_m_o_d_e This option may be used for specifying what mode should be + used for authentication. Note that this option is only use- + ful if tteellnneettdd has been compiled with support for the + AUTHENTICATION option. There are several valid values for + _a_u_t_h_m_o_d_e: + + 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 --aa vvaalliidd. + + otp Only allow authenticated connections (as with --aa + uusseerr) and also logins with one-time passwords (OTPs). + This option will call login with an option so that + only OTPs are accepted. The user can of course still + type secret information at the prompt. + + 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.

Normally tteellnneettdd 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. + + --rr _l_o_w_p_t_y_-_h_i_g_h_p_t_y + This option is only enabled when tteellnneettdd 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 _l_o_w_p_t_y or _h_i_g_h_p_t_y may be omitted to allow changing + either end of the search range. If _l_o_w_p_t_y is omitted, the - + character is still required so that tteellnneettdd can differenti- + ate _h_i_g_h_p_t_y from _l_o_w_p_t_y. + + --SS _t_o_s + + --uu _l_e_n 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 _l_e_n, 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 --uu00 indicates that only dotted deci- + mal addresses should be put into the _u_t_m_p file. + + --UU This option causes tteellnneettdd to refuse connections from ad- + dresses that cannot be mapped back into a symbolic name via + the gethostbyaddr(3) routine. + + --XX _a_u_t_h_t_y_p_e This option is only valid if tteellnneettdd has been built with + support for the authentication option.

TTeellnneettdd 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, tteellnneettdd 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)). + + TTeellnneettdd 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 tteellnneettdd is compiled with support for data + encryption, and indicates a willingness to decrypt the + data stream. + + TTeellnneettdd 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 tteellnneettdd is compiled with support for + linemode, and requests that the client do line by line + processing. + + DO TIMING-MARK Only sent if tteellnneettdd 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 [--kk] option can be used to + disable this. + + DO AUTHENTICATION Only sent if tteellnneettdd is compiled with support for au- + thentication, and indicates a willingness to receive + authentication information for automatic login. + + DO ENCRYPT Only sent if tteellnneettdd is compiled with support for data + encryption, and indicates a willingness to decrypt the + data stream. + +EENNVVIIRROONNMMEENNTT +FFIILLEESS + /etc/services + /etc/inittab (UNICOS systems only) + /etc/iptos (if supported) + +SSEEEE AALLSSOO + telnet(1), login(1) + +SSTTAANNDDAARRDDSS + RRFFCC--885544 TELNET PROTOCOL SPECIFICATION + RRFFCC--885555 TELNET OPTION SPECIFICATIONS + RRFFCC--885566 TELNET BINARY TRANSMISSION + RRFFCC--885577 TELNET ECHO OPTION + + + RRFFCC--885588 TELNET SUPPRESS GO AHEAD OPTION + RRFFCC--885599 TELNET STATUS OPTION + RRFFCC--886600 TELNET TIMING MARK OPTION + RRFFCC--886611 TELNET EXTENDED OPTIONS - LIST OPTION + RRFFCC--888855 TELNET END OF RECORD OPTION + RRFFCC--11007733 Telnet Window Size Option + RRFFCC--11007799 Telnet Terminal Speed Option + RRFFCC--11009911 Telnet Terminal-Type Option + RRFFCC--11009966 Telnet X Display Location Option + RRFFCC--11112233 Requirements for Internet Hosts -- Application and Support + RRFFCC--11118844 Telnet Linemode Option + RRFFCC--11337722 Telnet Remote Flow Control Option + RRFFCC--11441166 Telnet Authentication Option + RRFFCC--11441111 Telnet Authentication: Kerberos Version 4 + RRFFCC--11441122 Telnet Authentication: SPX + RRFFCC--11557711 Telnet Environment Option Interoperability Issues + RRFFCC--11557722 Telnet Environment Option + +BBUUGGSS + Some TELNET commands are only partially implemented. + + Because of bugs in the original 4.2 BSD telnet(1), tteellnneettdd performs some + dubious protocol exchanges to try to discover if the remote client is, in + fact, a 4.2 BSD telnet(1). + + Binary mode 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. + + TTeellnneettdd never sends TELNET IAC GA (go ahead) commands. + +4.2 Berkeley Distribution June 1, 1994 5 diff --git a/crypto/heimdal/appl/telnet/telnetd/telnetd.h b/crypto/heimdal/appl/telnet/telnetd/telnetd.h index fdda3d7..6504607 100644 --- a/crypto/heimdal/appl/telnet/telnetd/telnetd.h +++ b/crypto/heimdal/appl/telnet/telnetd/telnetd.h @@ -166,7 +166,6 @@ struct hostent *gethostbyname(const char *); #endif #ifdef KRB4 -#include <des.h> #include <krb.h> #endif diff --git a/crypto/heimdal/appl/telnet/telnetd/utility.c b/crypto/heimdal/appl/telnet/telnetd/utility.c index a2e542d..496152c 100644 --- a/crypto/heimdal/appl/telnet/telnetd/utility.c +++ b/crypto/heimdal/appl/telnet/telnetd/utility.c @@ -34,7 +34,7 @@ #define PRINTOPTIONS #include "telnetd.h" -RCSID("$Id: utility.c,v 1.23 2000/10/08 13:34:27 assar Exp $"); +RCSID("$Id: utility.c,v 1.25 2001/05/17 00:34:42 assar Exp $"); /* * utility functions performing io related tasks @@ -363,14 +363,20 @@ void fatal(int f, char *msg) } void -fatalperror(int f, const char *msg) +fatalperror_errno(int f, const char *msg, int error) { char buf[BUFSIZ]; - snprintf(buf, sizeof(buf), "%s: %s", msg, strerror(errno)); + snprintf(buf, sizeof(buf), "%s: %s", msg, strerror(error)); fatal(f, buf); } +void +fatalperror(int f, const char *msg) +{ + fatalperror_errno(f, msg, errno); +} + char editedhost[32]; void edithost(char *pat, char *host) |
