DDEESSCCRRIIPPTTIIOONN
     FFttpp is the user interface to the ARPANET standard File Transfer Protocol.
     The program allows a user to transfer files to and from a remote network
     site.

     Modifications has been made so that it almost follows the ftpsec Internet
     draft.

     Options may be specified at the command line, or to the command inter-
     preter.

     --tt    Enables packet tracing.

     --vv    Verbose option forces ffttpp to show all responses from the remote
           server, as well as report on data transfer statistics.

     --nn    Restrains ffttpp from attempting ``auto-login'' upon initial connec-
           tion.  If auto-login is enabled, ffttpp will check the _._n_e_t_r_c (see be-
           low) file in the user's home directory for an entry describing an
           account on the remote machine.  If no entry exists, ffttpp will prompt
           for the remote machine login name (default is the user identity on
           the local machine), and, if necessary, prompt for a password and an
           account with which to login.

     --ii    Turns off interactive prompting during multiple file transfers.

     --pp    Turn on passive mode.

     --dd    Enables debugging.

     --gg    Disables file name globbing.

     ----nnoo--ggssss--bbiinnddiinnggss
           use GSS-API bindings when talking to peer (ie make sure IP address-
           es match).

     --ll    Disables command line editing.

     The client host with which ffttpp is to communicate may be specified on the
     command line.  If this is done, ffttpp will immediately attempt to establish
     a connection to an FTP server on that host; otherwise, ffttpp will enter its
     command interpreter and await instructions from the user.  When ffttpp is
     awaiting commands from the user the prompt `ftp>' is provided to the us-
     er.  The following commands are recognized by ffttpp:

     !! [_c_o_m_m_a_n_d [_a_r_g_s]]
                 Invoke an interactive shell on the local machine.  If there
                 are arguments, the first is taken to be a command to execute
                 directly, with the rest of the arguments as its arguments.

     $$ _m_a_c_r_o_-_n_a_m_e [_a_r_g_s]
                 Execute the macro _m_a_c_r_o_-_n_a_m_e that was defined with the mmaaccddeeff
                 command.  Arguments are passed to the macro unglobbed.

     aaccccoouunntt [_p_a_s_s_w_d]
                 Supply a supplemental password required by a remote system
                 for access to resources once a login has been successfully
                 completed.  If no argument is included, the user will be
                 prompted for an account password in a non-echoing input mode.

     aappppeenndd _l_o_c_a_l_-_f_i_l_e [_r_e_m_o_t_e_-_f_i_l_e]
                 Append a local file to a file on the remote machine.  If
                 _r_e_m_o_t_e_-_f_i_l_e is left unspecified, the local file name is used
                 in naming the remote file after being altered by any nnttrraannss
                 or nnmmaapp setting.  File transfer uses the current settings for
                 ttyyppee, ffoorrmmaatt, mmooddee, and ssttrruuccttuurree.

     aasscciiii       Set the file transfer ttyyppee to network ASCII. This is the de-
                 fault type.

     bbeellll        Arrange that a bell be sounded after each file transfer com-
                 mand is completed.

     bbiinnaarryy      Set the file transfer ttyyppee to support binary image transfer.

     bbyyee         Terminate the FTP session with the remote server and exit
                 ffttpp. An end of file will also terminate the session and exit.

     ccaassee        Toggle remote computer file name case mapping during mmggeett
                 commands.  When ccaassee is on (default is off), remote computer
                 file names with all letters in upper case are written in the
                 local directory with the letters mapped to lower case.

     ccdd _r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y
                 Change the working directory on the remote machine to _r_e_m_o_t_e_-
                 _d_i_r_e_c_t_o_r_y.

     ccdduupp        Change the remote machine working directory to the parent of
                 the current remote machine working directory.

     cchhmmoodd _m_o_d_e _f_i_l_e_-_n_a_m_e
                 Change the permission modes of the file _f_i_l_e_-_n_a_m_e on the re-
                 mote sytem to _m_o_d_e.

     cclloossee       Terminate the FTP session with the remote server, and return
                 to the command interpreter.  Any defined macros are erased.

     ccrr          Toggle carriage return stripping during ascii type file re-
                 trieval.  Records are denoted by a carriage return/linefeed
                 sequence during ascii type file transfer.  When ccrr is on (the
                 default), carriage returns are stripped from this sequence to
                 conform with the UNIX single linefeed record delimiter.
                 Records on non-UNIX remote systems may contain single line-
                 feeds; when an ascii type transfer is made, these linefeeds
                 may be distinguished from a record delimiter only when ccrr is
                 off.

     ddeelleettee _r_e_m_o_t_e_-_f_i_l_e
                 Delete the file _r_e_m_o_t_e_-_f_i_l_e on the remote machine.

     ddeebbuugg [_d_e_b_u_g_-_v_a_l_u_e]
                 Toggle debugging mode.  If an optional _d_e_b_u_g_-_v_a_l_u_e is speci-
                 fied it is used to set the debugging level.  When debugging
                 is on, ffttpp prints each command sent to the remote machine,
                 preceded by the string `-->'

     ddiirr [_r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y] [_l_o_c_a_l_-_f_i_l_e]
                 Print a listing of the directory contents in the directory,
                 _r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y, and, optionally, placing the output in
                 _l_o_c_a_l_-_f_i_l_e. If interactive prompting is on, ffttpp will prompt
                 the user to verify that the last argument is indeed the tar-
                 get local file for receiving ddiirr output.  If no directory is
                 specified, the current working directory on the remote ma-
                 chine is used.  If no local file is specified, or _l_o_c_a_l_-_f_i_l_e
                 is --, output comes to the terminal.

     ddiissccoonnnneecctt  A synonym for _c_l_o_s_e.

     ffoorrmm _f_o_r_m_a_t
                 Set the file transfer ffoorrmm to _f_o_r_m_a_t. The default format is
                 ``file''.

     ggeett _r_e_m_o_t_e_-_f_i_l_e [_l_o_c_a_l_-_f_i_l_e]
                 Retrieve the _r_e_m_o_t_e_-_f_i_l_e and store it on the local machine.
                 If the local file name is not specified, it is given the same
                 name it has on the remote machine, subject to alteration by
                 the current ccaassee, nnttrraannss, and nnmmaapp settings.  The current
                 settings for ttyyppee, ffoorrmm, mmooddee, and ssttrruuccttuurree are used while
                 transferring the file.

     gglloobb        Toggle filename expansion for mmddeelleettee, mmggeett and mmppuutt. If
                 globbing is turned off with gglloobb, the file name arguments are
                 taken literally and not expanded.  Globbing for mmppuutt is done
                 as in csh(1).  For mmddeelleettee and mmggeett, each remote file name is
                 expanded separately on the remote machine and the lists are
                 not merged.  Expansion of a directory name is likely to be
                 different from expansion of the name of an ordinary file: the
                 exact result depends on the foreign operating system and ftp
                 server, and can be previewed by doing `mls remote-files -'.
                 As a security measure, remotely globbed files that starts
                 with `/' or contains `../', will not be automatically re-
                 ceived. If you have interactive prompting turned off, these
                 filenames will be ignored.  Note: mmggeett and mmppuutt are not meant
                 to transfer entire directory subtrees of files.  That can be
                 done by transferring a tar(1) archive of the subtree (in bi-
                 nary mode).

     hhaasshh        Toggle hash-sign (``#'') printing for each data block trans-
                 ferred.  The size of a data block is 1024 bytes.

     hheellpp [_c_o_m_m_a_n_d]
                 Print an informative message about the meaning of _c_o_m_m_a_n_d. If
                 no argument is given, ffttpp prints a list of the known com-
                 mands.

     iiddllee [_s_e_c_o_n_d_s]
                 Set the inactivity timer on the remote server to _s_e_c_o_n_d_s sec-
                 onds.  If _s_e_c_o_n_d_s is omitted, the current inactivity timer is
                 printed.

     llccdd [_d_i_r_e_c_t_o_r_y]
                 Change the working directory on the local machine.  If no
                 _d_i_r_e_c_t_o_r_y is specified, the user's home directory is used.

     llss [_r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y] [_l_o_c_a_l_-_f_i_l_e]
                 Print a listing of the contents of a directory on the remote
                 machine.  The listing includes any system-dependent informa-
                 tion that the server chooses to include; for example, most
                 UNIX systems will produce output from the command `ls -l'.
                 (See also nnlliisstt.) If _r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y is left unspecified,
                 the current working directory is used.  If interactive
                 prompting is on, ffttpp will prompt the user to verify that the
                 last argument is indeed the target local file for receiving
                 llss output.  If no local file is specified, or if _l_o_c_a_l_-_f_i_l_e
                 is `--', the output is sent to the terminal.

     mmaaccddeeff _m_a_c_r_o_-_n_a_m_e
                 Define a macro.  Subsequent lines are stored as the macro
                 _m_a_c_r_o_-_n_a_m_e; a null line (consecutive newline characters in a
                 file or carriage returns from the terminal) terminates macro
                 input mode.  There is a limit of 16 macros and 4096 total
                 characters in all defined macros.  Macros remain defined un-
                 til a cclloossee command is executed.  The macro processor inter-
                 prets `$' and `\' as special characters.  A `$' followed by a
                 number (or numbers) is replaced by the corresponding argument
                 on the macro invocation command line.  A `$' followed by an
                 `i' signals that macro processor that the executing macro is
                 to be looped.  On the first pass `$i' is replaced by the
                 first argument on the macro invocation command line, on the
                 second pass it is replaced by the second argument, and so on.
                 A `\' followed by any character is replaced by that charac-
                 ter.  Use the `\' to prevent special treatment of the `$'.

     mmddeelleettee [_r_e_m_o_t_e_-_f_i_l_e_s]
                 Delete the _r_e_m_o_t_e_-_f_i_l_e_s on the remote machine.

     mmddiirr _r_e_m_o_t_e_-_f_i_l_e_s _l_o_c_a_l_-_f_i_l_e
                 Like ddiirr, except multiple remote files may be specified.  If
                 interactive prompting is on, ffttpp will prompt the user to ver-
                 ify that the last argument is indeed the target local file
                 for receiving mmddiirr output.

     mmggeett _r_e_m_o_t_e_-_f_i_l_e_s
                 Expand the _r_e_m_o_t_e_-_f_i_l_e_s on the remote machine and do a ggeett
                 for each file name thus produced.  See gglloobb for details on
                 the filename expansion.  Resulting file names will then be
                 processed according to ccaassee, nnttrraannss, and nnmmaapp settings.
                 Files are transferred into the local working directory, which
                 can be changed with `lcd directory'; new local directories
                 can be created with `! mkdir directory'.

     mmkkddiirr _d_i_r_e_c_t_o_r_y_-_n_a_m_e
                 Make a directory on the remote machine.

     mmllss _r_e_m_o_t_e_-_f_i_l_e_s _l_o_c_a_l_-_f_i_l_e
                 Like nnlliisstt, except multiple remote files may be specified,
                 and the _l_o_c_a_l_-_f_i_l_e must be specified.  If interactive prompt-
                 ing is on, ffttpp will prompt the user to verify that the last
                 argument is indeed the target local file for receiving mmllss
                 output.

     mmooddee [_m_o_d_e_-_n_a_m_e]
                 Set the file transfer mmooddee to _m_o_d_e_-_n_a_m_e. The default mode is
                 ``stream'' mode.

     mmooddttiimmee _f_i_l_e_-_n_a_m_e
                 Show the last modification time of the file on the remote ma-
                 chine.

     mmppuutt _l_o_c_a_l_-_f_i_l_e_s
                 Expand wild cards in the list of local files given as argu-
                 ments and do a ppuutt for each file in the resulting list.  See
                 gglloobb for details of filename expansion.  Resulting file names
                 will then be processed according to nnttrraannss and nnmmaapp settings.

     nneewweerr _f_i_l_e_-_n_a_m_e
                 Get the file only if the modification time of the remote file
                 is more recent that the file on the current system.  If the
                 file does not exist on the current system, the remote file is
                 considered nneewweerr. Otherwise, this command is identical to
                 _g_e_t.

     nnlliisstt [_r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y] [_l_o_c_a_l_-_f_i_l_e]
                 Print a  list of the files in a directory on the remote ma-
                 chine.  If _r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y is left unspecified, the current
                 working directory is used.  If interactive prompting is on,
                 ffttpp will prompt the user to verify that the last argument is
                 indeed the target local file for receiving nnlliisstt output.  If
                 no local file is specified, or if _l_o_c_a_l_-_f_i_l_e is --, the output
                 is sent to the terminal.

     nnmmaapp [_i_n_p_a_t_t_e_r_n _o_u_t_p_a_t_t_e_r_n]
                 Set or unset the filename mapping mechanism.  If no arguments
                 are specified, the filename mapping mechanism is unset.  If
                 arguments are specified, remote filenames are mapped during
                 mmppuutt commands and ppuutt commands issued without a specified re-
                 mote target filename.  If arguments are specified, local
                 filenames are mapped during mmggeett commands and ggeett commands
                 issued without a specified local target filename.  This com-
                 mand is useful when connecting to a non-UNIX remote computer
                 with different file naming conventions or practices.  The
                 mapping follows the pattern set by _i_n_p_a_t_t_e_r_n and _o_u_t_p_a_t_t_e_r_n.
                 [_I_n_p_a_t_t_e_r_n] is a template for incoming filenames (which may
                 have already been processed according to the nnttrraannss and ccaassee
                 settings).  Variable templating is accomplished by including
                 the sequences `$1', `$2', ..., `$9' in _i_n_p_a_t_t_e_r_n. Use `\' to
                 prevent this special treatment of the `$' character.  All
                 other characters are treated literally, and are used to de-
                 termine the nnmmaapp [_i_n_p_a_t_t_e_r_n] variable values.  For example,
                 given _i_n_p_a_t_t_e_r_n $1.$2 and the remote file name "mydata.data",
                 $1 would have the value "mydata", and $2 would have the value
                 "data".  The _o_u_t_p_a_t_t_e_r_n determines the resulting mapped file-
                 name.  The sequences `$1', `$2', ...., `$9' are replaced by
                 any value resulting from the _i_n_p_a_t_t_e_r_n template.  The se-
                 quence `$0' is replace by the original filename.  Additional-
                 ly, the sequence `[_s_e_q_1, _s_e_q_2]' is replaced by [_s_e_q_1] if _s_e_q_1
                 is not a null string; otherwise it is replaced by _s_e_q_2. For
                 example, the command

                       nmap $1.$2.$3 [$1,$2].[$2,file]

                 would yield the output filename "myfile.data" for input file-
                 names "myfile.data" and "myfile.data.old", "myfile.file" for
                 the input filename "myfile", and "myfile.myfile" for the in-
                 put filename ".myfile".  Spaces may be included in
                 _o_u_t_p_a_t_t_e_r_n, as in the example: `nmap $1 sed "s/  *$//" > $1'

                 Set or unset the filename character translation mechanism.
                 If no arguments are specified, the filename character trans-
                 lation mechanism is unset.  If arguments are specified, char-
                 acters in remote filenames are translated during mmppuutt com-
                 mands and ppuutt commands issued without a specified remote tar-
                 get filename.  If arguments are specified, characters in lo-
                 cal filenames are translated during mmggeett commands and ggeett
                 commands issued without a specified local target filename.
                 This command is useful when connecting to a non-UNIX remote
                 computer with different file naming conventions or practices.
                 Characters in a filename matching a character in _i_n_c_h_a_r_s are
                 replaced with the corresponding character in _o_u_t_c_h_a_r_s. If the
                 character's position in _i_n_c_h_a_r_s is longer than the length of
                 _o_u_t_c_h_a_r_s, the character is deleted from the file name.

     ooppeenn _h_o_s_t [_p_o_r_t]
                 Establish a connection to the specified _h_o_s_t FTP server.  An
                 optional port number may be supplied, in which case, ffttpp will
                 attempt to contact an FTP server at that port.  If the aauuttoo--
                 llooggiinn option is on (default), ffttpp will also attempt to auto-

                 matically log the user in to the FTP server (see below).

     ppaassssiivvee     Toggle passive mode.  If passive mode is turned on (default
                 is off), the ftp client will send a PASV command for all data
                 connections instead of the usual PORT command.  The PASV com-
                 mand requests that the remote server open a port for the data
                 connection and return the address of that port.  The remote
                 server listens on that port and the client connects to it.
                 When using the more traditional PORT command, the client lis-
                 tens on a port and sends that address to the remote server,
                 who connects back to it.  Passive mode is useful when using
                 ffttpp through a gateway router or host that controls the direc-
                 tionality of traffic.  (Note that though ftp servers are re-
                 quired to support the PASV command by RFC 1123, some do not.)

     pprroommpptt      Toggle interactive prompting.  Interactive prompting occurs
                 during multiple file transfers to allow the user to selec-
                 tively retrieve or store files.  If prompting is turned off
                 (default is on), any mmggeett or mmppuutt will transfer all files,
                 and any mmddeelleettee will delete all files.

     pprrooxxyy _f_t_p_-_c_o_m_m_a_n_d
                 Execute an ftp command on a secondary control connection.
                 This command allows simultaneous connection to two remote ftp
                 servers for transferring files between the two servers.  The
                 first pprrooxxyy command should be an ooppeenn, to establish the sec-
                 ondary control connection.  Enter the command "proxy ?" to
                 see other ftp commands executable on the secondary connec-
                 tion.  The following commands behave differently when pref-
                 aced by pprrooxxyy: ooppeenn will not define new macros during the au-
                 to-login process, cclloossee will not erase existing macro defini-
                 tions, ggeett and mmggeett transfer files from the host on the pri-
                 mary control connection to the host on the secondary control
                 connection, and ppuutt, mmppuutt, and aappppeenndd transfer files from the
                 host on the secondary control connection to the host on the
                 primary control connection.  Third party file transfers de-
                 pend upon support of the ftp protocol PASV command by the
                 server on the secondary control connection.

     ppuutt _l_o_c_a_l_-_f_i_l_e [_r_e_m_o_t_e_-_f_i_l_e]

                 left unspecified, the local file name is used after process-
                 ing according to any nnttrraannss or nnmmaapp settings in naming the
                 remote file.  File transfer uses the current settings for
                 ttyyppee, ffoorrmmaatt, mmooddee, and ssttrruuccttuurree.

                 smaller than _r_e_m_o_t_e_-_f_i_l_e, _l_o_c_a_l_-_f_i_l_e is presumed to be a par-
                 tially transferred copy of _r_e_m_o_t_e_-_f_i_l_e and the transfer is
                 continued from the apparent point of failure.  This command
                 is useful when transferring very large files over networks

                 that are prone to dropping connections.

     rreemmootteehheellpp [_c_o_m_m_a_n_d_-_n_a_m_e]

     rruunniiqquuee     Toggle storing of files on the local system with unique file-
                 names.  If a file already exists with a name equal to the
                 target local filename for a ggeett or mmggeett command, a ".1" is
                 appended to the name.  If the resulting name matches another
                 existing file, a ".2" is appended to the original name.  If
                 this process continues up to ".99", an error message is
                 printed, and the transfer does not take place.  The generated
                 unique filename will be reported.  Note that rruunniiqquuee will not
                 affect local files generated from a shell command (see be-
                 low).  The default value is off.

     sseennddppoorrtt    Toggle the use of PORT commands.  By default, ffttpp will at-
                 tempt to use a PORT command when establishing a connection
                 for each data transfer.  The use of PORT commands can prevent
                 delays when performing multiple file transfers.  If the PORT
                 command fails, ffttpp will use the default data port.  When the
                 use of PORT commands is disabled, no attempt will be made to
                 use PORT commands for each data transfer.  This is useful for
                 certain FTP implementations which do ignore PORT commands
                 but, incorrectly, indicate they've been accepted.

     ssiittee _a_r_g_1 _a_r_g_2 _._._.

                 Set the default umask on the remote server to _n_e_w_m_a_s_k. If
                 _n_e_w_m_a_s_k is omitted, the current umask is printed.

     uusseerr _u_s_e_r_-_n_a_m_e [_p_a_s_s_w_o_r_d] [_a_c_c_o_u_n_t]

                 is not specified and the server requires it, ffttpp will prompt
                 the user for it (after disabling local echo).  If an _a_c_c_o_u_n_t
                 field is not specified, and the FTP server requires it, the
                 user will be prompted for it.  If an _a_c_c_o_u_n_t field is speci-
                 fied, an account command will be relayed to the remote server
                 after the login sequence is completed if the remote server
                 did not require it for logging in.  Unless ffttpp is invoked
                 with ``auto-login'' disabled, this process is done automati-
                 cally on initial connection to the FTP server.

     vveerrbboossee     Toggle verbose mode.  In verbose mode, all responses from the
                 FTP server are displayed to the user.  In addition, if ver-
                 bose is on, when a file transfer completes, statistics re-
                 garding the efficiency of the transfer are reported.  By de-

AABBOORRTTIINNGG AA FFIILLEE TTRRAANNSSFFEERR
     To abort a file transfer, use the terminal interrupt key (usually Ctrl-
     C).  Sending transfers will be immediately halted.  Receiving transfers
     will be halted by sending a ftp protocol ABOR command to the remote serv-
     er, and discarding any further data received.  The speed at which this is
     accomplished depends upon the remote server's support for ABOR process-
     ing.  If the remote server does not support the ABOR command, an `ftp>'
     prompt will not appear until the remote server has completed sending the
     requested file.


     The terminal interrupt key sequence will be ignored when ffttpp has complet-
     ed any local processing and is awaiting a reply from the remote server.
     A long delay in this mode may result from the ABOR processing described
     above, or from unexpected behavior by the remote server, including viola-
     tions of the ftp protocol.  If the delay results from unexpected remote
     server behavior, the local ffttpp program must be killed by hand.

FFIILLEE NNAAMMIINNGG CCOONNVVEENNTTIIOONNSS
     Files specified as arguments to ffttpp commands are processed according to
     the following rules.

     1.   If the file name `--' is specified, the _s_t_d_i_n (for reading) or _s_t_d_o_u_t
          (for writing) is used.

     2.   If the first character of the file name is `|', the remainder of the
          argument is interpreted as a shell command.  FFttpp then forks a shell,
          using popen(3) with the argument supplied, and reads (writes) from
          the stdout (stdin).  If the shell command includes spaces, the argu-
          ment must be quoted; e.g.  ``" ls -lt"''.  A particularly useful ex-
          ample of this mechanism is: ``dir more''.

     3.   Failing the above checks, if ``globbing'' is enabled, local file
          names are expanded according to the rules used in the csh(1);  c.f.
          the gglloobb command.  If the ffttpp command expects a single local file
          (.e.g.  ppuutt), only the first filename generated by the "globbing"
          operation is used.

     4.   For mmggeett commands and ggeett commands with unspecified local file
          names, the local filename is the remote filename, which may be al-
          tered by a ccaassee, nnttrraannss, or nnmmaapp setting.  The resulting filename
          may then be altered if rruunniiqquuee is on.

     5.   For mmppuutt commands and ppuutt commands with unspecified remote file
          names, the remote filename is the local filename, which may be al-
          tered by a nnttrraannss or nnmmaapp setting.  The resulting filename may then
          be altered by the remote server if ssuunniiqquuee is on.

FFIILLEE TTRRAANNSSFFEERR PPAARRAAMMEETTEERRSS
     The FTP specification specifies many parameters which may affect a file
     transfer.  The ttyyppee may be one of ``ascii'', ``image'' (binary),
     ``ebcdic'', and ``local byte size'' (for PDP-10's and PDP-20's mostly).
     FFttpp supports the ascii and image types of file transfer, plus local byte
     size 8 for tteenneexx mode transfers.

     FFttpp supports only the default values for the remaining file transfer pa-
     rameters: mmooddee, ffoorrmm, and ssttrruucctt.

TTHHEE ..nneettrrcc FFIILLEE
     The _._n_e_t_r_c file contains login and initialization information used by the
     auto-login process.  It resides in the user's home directory.  The fol-
     lowing tokens are recognized; they may be separated by spaces, tabs, or
     new-lines:

     mmaacchhiinnee _n_a_m_e
               Identify a remote machine _n_a_m_e. The auto-login process searches
               the _._n_e_t_r_c file for a mmaacchhiinnee token that matches the remote ma-
               chine specified on the ffttpp command line or as an ooppeenn command
               argument.  Once a match is made, the subsequent _._n_e_t_r_c tokens
               are processed, stopping when the end of file is reached or an-
               other mmaacchhiinnee or a ddeeffaauulltt token is encountered.

     ddeeffaauulltt   This is the same as mmaacchhiinnee _n_a_m_e except that ddeeffaauulltt matches
               any name.  There can be only one ddeeffaauulltt token, and it must be
               after all mmaacchhiinnee tokens.  This is normally used as:


                     default login anonymous password user@site

               thereby giving the user _a_u_t_o_m_a_t_i_c anonymous ftp login to ma-
               chines not specified in _._n_e_t_r_c. This can be overridden by using
               the --nn flag to disable auto-login.

     llooggiinn _n_a_m_e
               Identify a user on the remote machine.  If this token is pre-
               sent, the auto-login process will initiate a login using the
               specified _n_a_m_e.

     ppaasssswwoorrdd _s_t_r_i_n_g
               Supply a password.  If this token is present, the auto-login
               process will supply the specified string if the remote server
               requires a password as part of the login process.  Note that if
               this token is present in the _._n_e_t_r_c file for any user other
               than _a_n_o_n_y_m_o_u_s, ffttpp will abort the auto-login process if the
               _._n_e_t_r_c is readable by anyone besides the user.

     aaccccoouunntt _s_t_r_i_n_g
               Supply an additional account password.  If this token is pre-
               sent, the auto-login process will supply the specified string
               if the remote server requires an additional account password,
               or the auto-login process will initiate an ACCT command if it
               does not.

     mmaaccddeeff _n_a_m_e
               Define a macro.  This token functions like the ffttpp mmaaccddeeff com-
               mand functions.  A macro is defined with the specified name;
               its contents begin with the next _._n_e_t_r_c line and continue until
               a null line (consecutive new-line characters) is encountered.
               If a macro named iinniitt is defined, it is automatically executed
               as the last step in the auto-login process.
