TTeellnneettdd is normally invoked by the internet - server (see inetd(8)) for requests to connect to the TELNET port as in- - dicated by the _/_e_t_c_/_s_e_r_v_i_c_e_s file (see services(5)). 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. All user ver- - ification will happen through the login(1) program. - - --BB Ignored. - - --DD _d_e_b_u_g_m_o_d_e - This option may be used for debugging purposes. This allows - tteellnneettdd to print out debugging information to the connec- - tion, allowing the user to see what tteellnneettdd is doing. There - are several possible values for _d_e_b_u_g_m_o_d_e: - - ooppttiioonnss Prints information about the negotiation of TELNET - options. - - rreeppoorrtt Prints the ooppttiioonnss information, plus some addi- - tional information about what processing is going - on. - - nneettddaattaa Displays the data stream received by tteellnneettdd. - - ppttyyddaattaa Displays data written to the pty. - - eexxeerrcciissee Has not been implemented yet. - - --hh Disables the printing of host-specific information before - login has been completed. - - --kk - - --ll Ignored. - - --nn Disable TCP keep-alives. 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. It disables the use - of _a_u_t_h_t_y_p_e authentication, and can be used to temporarily - disable a specific authentication type without having to re- - compile tteellnneettdd. - - --LL --ppaatthhnnaammee - Specify pathname to an alternative login program. - - TTeellnneettdd 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. 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 |
