679 command requests that the remote server open a port for the data connection
680 and return the address of that port. The remote server listens on that
681 port and the client connects to it. When using the more traditional
683 command, the client listens on a port and sends that address to the remote
684 server, who connects back to it. Passive mode is useful when using

854 Toggle data port range restrictions.
855 When not operating in passive mode, the
857 client program requests that the remote server open a connection back
858 to the client host on a separate data port. In previous versions, that
859 remote port fell in the range 1024..4999. However, most firewall setups
860 filter that range of TCP ports because other services reside there.
861 The default behavior now is for the client to request that the server
862 connect back to the client using the port range 40000..44999. Firewall
863 administrators can chose to allow TCP connections in that range, if they
864 deem it to not be a security risk.
865 .It Ic rmdir Ar directory-name
866 Delete a directory on the remote machine.
868 Toggle storing of files on the local system with unique filenames.
869 If a file already exists with a name equal to the target
874 command, a ".1" is appended to the name.
875 If the resulting name matches another existing file,
876 a ".2" is appended to the original name.
877 If this process continues up to ".99", an error
878 message is printed, and the transfer does not take place.
879 The generated unique filename will be reported.
882 will not affect local files generated from a shell command

1034 statistics will be written to the standard error output, in the
1035 same format as the standard completion message.
1036 .Sh AUTO-FETCHING FILES
1037 In addition to standard commands, this version of
1039 supports an auto-fetch feature.
1040 To enable auto-fetch, simply pass the list of hostnames/files
1041 on the command line.
1043 The following formats are valid syntax for an auto-fetch element:
1044 .Bl -tag -width "host:/file"
1048 .It ftp://[user:password@]host[:port]/file
1049 An ftp URL, retrieved using the ftp protocol if
1052 Otherwise, transfer using http via the proxy defined in
1058 isn't defined, login as
1062 .It http://host[:port]/file

1073 will connect to the site and
1075 to the directory given as the path, and leave the user in interactive
1076 mode ready for further input.
1078 If successive auto-fetch ftp elements refer to the same host, then
1079 the connection is maintained between transfers, reducing overhead on
1080 connection creation and deletion.

1099 .Sh ABORTING A FILE TRANSFER
1100 To abort a file transfer, use the terminal interrupt key
1102 Sending transfers will be immediately halted.
1103 Receiving transfers will be halted by sending a ftp protocol
1105 command to the remote server, and discarding any further data received.
1106 The speed at which this is accomplished depends upon the remote
1107 server's support for
1110 If the remote server does not support the
1114 prompt will not appear until the remote server has completed
1115 sending the requested file.
1117 The terminal interrupt key sequence will be ignored when
1119 has completed any local processing and is awaiting a reply
1120 from the remote server.
1121 A long delay in this mode may result from the ABOR processing described
1122 above, or from unexpected behavior by the remote server, including
1123 violations of the ftp protocol.
1124 If the delay results from unexpected remote server behavior, the local
1126 program must be killed by hand.
1127 .Sh FILE NAMING CONVENTIONS
1128 Files specified as arguments to
1130 commands are processed according to the following rules.
1139 (for writing) is used.
1141 If the first character of the file name is
1144 remainder of the argument is interpreted as a shell command.
1146 then forks a shell, using
1148 with the argument supplied, and reads (writes) from the stdin
1150 If the shell command includes spaces, the argument
1151 must be quoted; e.g.
1152 \*(Lq" ls -lt"\*(Rq.
1154 useful example of this mechanism is: \*(Lqdir \&|more\*(Rq.
1156 Failing the above checks, if ``globbing'' is enabled,
1157 local file names are expanded
1158 according to the rules used in the
1165 command expects a single local file (.e.g.
1167 only the first filename generated by the "globbing" operation is used.

1198 .Sh FILE TRANSFER PARAMETERS
1199 The FTP specification specifies many parameters which may
1200 affect a file transfer.
1203 may be one of \*(Lqascii\*(Rq, \*(Lqimage\*(Rq (binary),
1204 \*(Lqebcdic\*(Rq, and \*(Lqlocal byte size\*(Rq (for

1211 plus local byte size 8 for
1216 supports only the default values for the remaining
1217 file transfer parameters:
1225 file contains login and initialization information
1226 used by the auto-login process.
1227 It resides in the user's home directory.
1228 The following tokens are recognized; they may be separated by spaces,
1230 .Bl -tag -width password
1231 .It Ic machine Ar name
1232 Identify a remote machine
1234 The auto-login process searches the
1238 token that matches the remote machine specified on the
1240 command line or as an
1243 Once a match is made, the subsequent
1245 tokens are processed,
1246 stopping when the end of file is reached or another
1250 token is encountered.
1258 There can be only one
1260 token, and it must be after all
1263 This is normally used as:
1265 .Dl default login anonymous password user@site
1267 thereby giving the user
1269 anonymous ftp login to
1270 machines not specified in
1272 This can be overridden
1275 flag to disable auto-login.
1276 .It Ic login Ar name
1277 Identify a user on the remote machine.
1278 If this token is present, the auto-login process will initiate
1279 a login using the specified
1281 .It Ic password Ar string
1283 If this token is present, the auto-login process will supply the
1284 specified string if the remote server requires a password as part
1285 of the login process.
1286 Note that if this token is present in the
1288 file for any user other
1292 will abort the auto-login process if the
1295 anyone besides the user.
1296 .It Ic account Ar string
1297 Supply an additional account password.
1298 If this token is present, the auto-login process will supply the
1299 specified string if the remote server requires an additional
1300 account password, or the auto-login process will initiate an
1302 command if it does not.
1303 .It Ic macdef Ar name
1305 This token functions like the
1309 A macro is defined with the specified name; its contents begin with the
1312 line and continue until a null line (consecutive new-line
1313 characters) is encountered.

1319 .Sh COMMAND LINE EDITING
1321 supports interactive command line editing, via the
1324 It is enabled with the
1326 command, and is enabled by default if input is from a tty.
1327 Previous lines can be recalled and edited with the arrow keys,
1328 and other GNU Emacs-style editing keys may be used as well.
1332 library is configured with a
1336 for more information.
1338 An extra key binding is available to
1340 to provide context sensitive command and filename completion
1341 (including remote file completion).
1342 To use this, bind a key to the
1346 By default, this is bound to the TAB key.

1350 .Bl -tag -width "FTP_PASSIVE_MODE"
1351 .It Ev FTP_PASSIVE_MODE
1352 Use passive mode FTP by default.

1399 Various features such as command line editing, context sensitive
1400 command and file completion, dynamic progress bar, automatic
1401 fetching of files, ftp and http URLs, and modification time
1402 preservation were implemented in
1404 by Luke Mewburn, with assistance from Jason Thorpe.
1406 Correct execution of many commands depends upon proper behavior
1407 by the remote server.
1409 An error in the treatment of carriage returns

1414 This correction may result in incorrect transfers of binary files
1417 servers using the ascii type.
1418 Avoid this problem by using the binary image type.
