Op Ar command Op Ar args -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. -.It Ic \&$ Ar macro-name Op Ar args -Execute the macro -.Ar macro-name -that was defined with the -.Ic macdef -command. -Arguments are passed to the macro unglobbed. -.It Ic account Op Ar passwd -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. -.It Ic append Ar local-file Op Ar remote-file -Append a local file to a file on the remote machine. -If -.Ar remote-file -is left unspecified, the local file name is used in naming the -remote file after being altered by any -.Ic ntrans -or -.Ic nmap -setting. -File transfer uses the current settings for -.Ic type , -.Ic format , -.Ic mode , -and -.Ic structure . -.It Ic ascii -Set the file transfer -.Ic type -to network -.Tn ASCII . -This is the default type. -.It Ic bell -Arrange that a bell be sounded after each file transfer -command is completed. -.It Ic binary -Set the file transfer -.Ic type -to support binary image transfer. -.It Ic bye -Terminate the -.Tn FTP -session with the remote server -and exit -.Nm ftp . -An end of file will also terminate the session and exit. -.It Ic case -Toggle remote computer file name case mapping during -.Ic mget -commands. -When -.Ic case -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. -.It Ic \&cd Ar remote-directory -Change the working directory on the remote machine -to -.Ar remote-directory . -.It Ic cdup -Change the remote machine working directory to the parent of the -current remote machine working directory. -.It Ic chmod Ar mode file-name -Change the permission modes of the file -.Ar file-name -on the remote -sytem to -.Ar mode . -.It Ic close -Terminate the -.Tn FTP -session with the remote server, and -return to the command interpreter. -Any defined macros are erased. -.It Ic \&cr -Toggle carriage return stripping during -ascii type file retrieval. -Records are denoted by a carriage return/linefeed sequence -during ascii type file transfer. -When -.Ic \&cr -is on (the default), carriage returns are stripped from this -sequence to conform with the -.Ux -single linefeed record -delimiter. -Records on -.Pf non\- Ns Ux -remote systems may contain single linefeeds; -when an ascii type transfer is made, these linefeeds may be -distinguished from a record delimiter only when -.Ic \&cr -is off. -.It Ic delete Ar remote-file -Delete the file -.Ar remote-file -on the remote machine. -.It Ic debug Op Ar debug-value -Toggle debugging mode. -If an optional -.Ar debug-value -is specified it is used to set the debugging level. -When debugging is on, -.Nm ftp -prints each command sent to the remote machine, preceded -by the string -.Ql \-\-> -.It Xo -.Ic dir -.Op Ar remote-directory -.Op Ar local-file -.Xc -Print a listing of the directory contents in the -directory, -.Ar remote-directory , -and, optionally, placing the output in -.Ar local-file . -If interactive prompting is on, -.Nm ftp -will prompt the user to verify that the last argument is indeed the -target local file for receiving -.Ic dir -output. -If no directory is specified, the current working -directory on the remote machine is used. -If no local -file is specified, or -.Ar local-file -is -.Fl , -output comes to the terminal. -.It Ic disconnect -A synonym for -.Ar close . -.It Ic form Ar format -Set the file transfer -.Ic form -to -.Ar format . -The default format is \*(Lqfile\*(Rq. -.It Ic get Ar remote-file Op Ar local-file -Retrieve the -.Ar remote-file -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 -.Ic case , -.Ic ntrans , -and -.Ic nmap -settings. -The current settings for -.Ic type , -.Ic form , -.Ic mode , -and -.Ic structure -are used while transferring the file. -.It Ic glob -Toggle filename expansion for -.Ic mdelete , -.Ic mget -and -.Ic mput . -If globbing is turned off with -.Ic glob , -the file name arguments -are taken literally and not expanded. -Globbing for -.Ic mput -is done as in -.Xr csh 1 . -For -.Ic mdelete -and -.Ic mget , -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 -.Ql mls remote-files \- . -As a security measure, remotely globbed files that starts with -.Sq / -or contains -.Sq ../ , -will not be automatically received. If you have interactive prompting -turned off, these filenames will be ignored. Note: -.Ic mget -and -.Ic mput -are not meant to transfer -entire directory subtrees of files. -That can be done by -transferring a -.Xr tar 1 -archive of the subtree (in binary mode). -.It Ic hash -Toggle hash-sign (``#'') printing for each data block -transferred. -The size of a data block is 1024 bytes. -.It Ic help Op Ar command -Print an informative message about the meaning of -.Ar command . -If no argument is given, -.Nm ftp -prints a list of the known commands. -.It Ic idle Op Ar seconds -Set the inactivity timer on the remote server to -.Ar seconds -seconds. -If -.Ar seconds -is omitted, the current inactivity timer is printed. -.It Ic lcd Op Ar directory -Change the working directory on the local machine. -If -no -.Ar directory -is specified, the user's home directory is used. -.It Xo -.Ic \&ls -.Op Ar remote-directory -.Op Ar local-file -.Xc -Print a listing of the contents of a -directory on the remote machine. -The listing includes any system-dependent information that the server -chooses to include;

-new local directories can be created with -.Ql "\&! mkdir directory" . -.It Ic mkdir Ar directory-name -Make a directory on the remote machine. -.It Ic mls Ar remote-files local-file -Like -.Ic nlist , -except multiple remote files may be specified, -and the -.Ar local-file -must be specified. -If interactive prompting is on, -.Nm ftp -will prompt the user to verify that the last argument is indeed the -target local file for receiving -.Ic mls -output. -.It Ic mode Op Ar mode-name -Set the file transfer -.Ic mode -to -.Ar mode-name . -The default mode is \*(Lqstream\*(Rq mode. -.It Ic modtime Ar file-name -Show the last modification time of the file on the remote machine. -.It Ic mput Ar local-files -Expand wild cards in the list of local files given as arguments -and do a -.Ic put -for each file in the resulting list. -See -.Ic glob -for details of filename expansion. -Resulting file names will then be processed according to -.Ic ntrans -and -.Ic nmap -settings. -.It Ic newer Ar file-name -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 -.Ic newer . -Otherwise, this command is identical to -.Ar get . -.It Xo -.Ic nlist -.Op Ar remote-directory -.Op Ar local-file -.Xc -Print a list of the files in a -directory on the remote machine. -If -.Ar remote-directory -is left unspecified, the current working directory is used. -If interactive prompting is on, -.Nm ftp -will prompt the user to verify that the last argument is indeed the -target local file for receiving -.Ic nlist -output. -If no local file is specified, or if -.Ar local-file -is -.Fl , -the output is sent to the terminal. -.It Ic nmap Op Ar inpattern outpattern -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 -.Ic mput -commands and -.Ic put -commands issued without a specified remote target filename. -If arguments are specified, local filenames are mapped during -.Ic mget -commands and -.Ic get -commands issued without a specified local target filename. -This command is useful when connecting to a -.No non\- Ns Ux -remote computer -with different file naming conventions or practices. -The mapping follows the pattern set by -.Ar inpattern -and -.Ar outpattern . -.Op Ar Inpattern -is a template for incoming filenames (which may have already been -processed according to the -.Ic ntrans -and -.Ic case -settings). -Variable templating is accomplished by including the -sequences `$1', `$2', ..., `$9' in -.Ar inpattern . -Use `\\' to prevent this special treatment of the `$' character. -All other characters are treated literally, and are used to determine the -.Ic nmap -.Op Ar inpattern -variable values. -For example, given -.Ar inpattern -$1.$2 and the remote file name "mydata.data", $1 would have the value -"mydata", and $2 would have the value "data". -The -.Ar outpattern -determines the resulting mapped filename. -The sequences `$1', `$2', ...., `$9' are replaced by any value resulting -from the -.Ar inpattern -template. -The sequence `$0' is replace by the original filename. -Additionally, the sequence -.Ql Op Ar seq1 , Ar seq2 -is replaced by -.Op Ar seq1 -if -.Ar seq1 -is not a null string; otherwise it is replaced by -.Ar seq2 . -For example, the command -.Pp -.Bd -literal -offset indent -compact -nmap $1.$2.$3 [$1,$2].[$2,file] -.Ed -.Pp -would yield -the output filename "myfile.data" for input filenames "myfile.data" and -"myfile.data.old", "myfile.file" for the input filename "myfile", and -"myfile.myfile" for the input filename ".myfile". -Spaces may be included in -.Ar outpattern , -as in the example: `nmap $1 sed "s/ *$//" > $1' . -Use the `\e' character to prevent special treatment -of the `$','[','[', and `,' characters. -.It Ic ntrans Op Ar inchars Op Ar outchars -Set or unset the filename character translation mechanism. -If no arguments are specified, the filename character -translation mechanism is unset. -If arguments are specified, characters in -remote filenames are translated during -.Ic mput -commands and -.Ic put -commands issued without a specified remote target filename. -If arguments are specified, characters in -local filenames are translated during -.Ic mget -commands and -.Ic get -commands issued without a specified local target filename. -This command is useful when connecting to a -.No non\- Ns Ux -remote computer -with different file naming conventions or practices. -Characters in a filename matching a character in -.Ar inchars -are replaced with the corresponding character in -.Ar outchars . -If the character's position in -.Ar inchars -is longer than the length of -.Ar outchars , -the character is deleted from the file name. -.It Ic open Ar host Op Ar port -Establish a connection to the specified -.Ar host -.Tn FTP -server. -An optional port number may be supplied, -in which case, -.Nm ftp -will attempt to contact an -.Tn FTP -server at that port. -If the -.Ic auto-login -option is on (default), -.Nm ftp -will also attempt to automatically log the user in to -the -.Tn FTP -server (see below). -.It Ic passive -Toggle passive mode. If passive mode is turned on -(default is off), the ftp client will -send a -.Dv PASV -command for all data connections instead of the usual -.Dv PORT -command. The -.Dv PASV -command 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 -.Dv PORT -command, the client listens on a port and sends that address to the remote -server, who connects back to it. Passive mode is useful when using -.Nm ftp -through a gateway router or host that controls the directionality of -traffic. -(Note that though ftp servers are required to support the -.Dv PASV -command by RFC 1123, some do not.) -.It Ic prompt -Toggle interactive prompting. -Interactive prompting -occurs during multiple file transfers to allow the -user to selectively retrieve or store files. -If prompting is turned off (default is on), any -.Ic mget -or -.Ic mput -will transfer all files, and any -.Ic mdelete -will delete all files. -.It Ic proxy Ar ftp-command -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 -.Ic proxy -command should be an -.Ic open , -to establish the secondary control connection. -Enter the command "proxy ?" to see other ftp commands executable on the -secondary connection. -The following commands behave differently when prefaced by -.Ic proxy : -.Ic open -will not define new macros during the auto-login process, -.Ic close -will not erase existing macro definitions, -.Ic get -and -.Ic mget -transfer files from the host on the primary control connection -to the host on the secondary control connection, and -.Ic put , -.Ic mput , -and -.Ic append -transfer files from the host on the secondary control connection -to the host on the primary control connection. -Third party file transfers depend upon support of the ftp protocol -.Dv PASV -command by the server on the secondary control connection. -.It Ic put Ar local-file Op Ar remote-file -Store a local file on the remote machine. -If -.Ar remote-file -is left unspecified, the local file name is used -after processing according to any -.Ic ntrans -or -.Ic nmap -settings -in naming the remote file. -File transfer uses the -current settings for -.Ic type , -.Ic format , -.Ic mode , -and -.Ic structure . -.It Ic pwd -Print the name of the current working directory on the remote -machine. -.It Ic quit -A synonym for -.Ic bye . -.It Ic quote Ar arg1 arg2 ... -The arguments specified are sent, verbatim, to the remote -.Tn FTP -server. -.It Ic recv Ar remote-file Op Ar local-file -A synonym for get. -.It Ic reget Ar remote-file Op Ar local-file -Reget acts like get, except that if -.Ar local-file -exists and is -smaller than -.Ar remote-file , -.Ar local-file -is presumed to be -a partially transferred copy of -.Ar remote-file -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. -.It Ic remotehelp Op Ar command-name -Request help from the remote -.Tn FTP -server. -If a -.Ar command-name -is specified it is supplied to the server as well. -.It Ic remotestatus Op Ar file-name -With no arguments, show status of remote machine. -If -.Ar file-name -is specified, show status of -.Ar file-name -on remote machine. -.It Xo -.Ic rename -.Op Ar from -.Op Ar to -.Xc -Rename the file -.Ar from -on the remote machine, to the file -.Ar to . -.It Ic reset -Clear reply queue. -This command re-synchronizes command/reply sequencing with the remote -ftp server. -Resynchronization may be necessary following a violation of the ftp protocol -by the remote server. -.It Ic restart Ar marker -Restart the immediately following -.Ic get -or -.Ic put -at the -indicated -.Ar marker . -On -.Ux -systems, marker is usually a byte -offset into the file. -.It Ic rmdir Ar directory-name -Delete a directory on the remote machine. -.It Ic runique -Toggle storing of files on the local system with unique filenames. -If a file already exists with a name equal to the target -local filename for a -.Ic get -or -.Ic mget -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 -.Ic runique -will not affect local files generated from a shell command -(see below). -The default value is off. -.It Ic send Ar local-file Op Ar remote-file -A synonym for put. -.It Ic sendport -Toggle the use of -.Dv PORT -commands. -By default, -.Nm ftp -will attempt to use a -.Dv PORT -command when establishing -a connection for each data transfer. -The use of -.Dv PORT -commands can prevent delays -when performing multiple file transfers. -If the -.Dv PORT -command fails, -.Nm ftp -will use the default data port. -When the use of -.Dv PORT -commands is disabled, no attempt will be made to use -.Dv PORT -commands for each data transfer. -This is useful -for certain -.Tn FTP -implementations which do ignore -.Dv PORT -commands but, incorrectly, indicate they've been accepted. -.It Ic site Ar arg1 arg2 ... -The arguments specified are sent, verbatim, to the remote -.Tn FTP -server as a -.Dv SITE -command. -.It Ic size Ar file-name -Return size of -.Ar file-name -on remote machine. -.It Ic status -Show the current status of -.Nm ftp . -.It Ic struct Op Ar struct-name -Set the file transfer -.Ar structure -to -.Ar struct-name . -By default \*(Lqstream\*(Rq structure is used. -.It Ic sunique -Toggle storing of files on remote machine under unique file names. -Remote ftp server must support ftp protocol -.Dv STOU -command for -successful completion. -The remote server will report unique name. -Default value is off. -.It Ic system -Show the type of operating system running on the remote machine. -.It Ic tenex -Set the file transfer type to that needed to -talk to -.Tn TENEX -machines. -.It Ic trace -Toggle packet tracing. -.It Ic type Op Ar type-name -Set the file transfer -.Ic type -to -.Ar type-name . -If no type is specified, the current type -is printed. -The default type is network -.Tn ASCII . -.It Ic umask Op Ar newmask -Set the default umask on the remote server to -.Ar newmask . -If -.Ar newmask -is omitted, the current umask is printed. -.It Xo -.Ic user Ar user-name -.Op Ar password -.Op Ar account -.Xc -Identify yourself to the remote -.Tn FTP -server. -If the -.Ar password -is not specified and the server requires it, -.Nm ftp -will prompt the user for it (after disabling local echo). -If an -.Ar account -field is not specified, and the -.Tn FTP -server -requires it, the user will be prompted for it. -If an -.Ar account -field is specified, 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 -.Nm ftp -is invoked with \*(Lqauto-login\*(Rq disabled, this -process is done automatically on initial connection to -the -.Tn FTP -server. -.It Ic verbose -Toggle verbose mode. -In verbose mode, all responses from -the -.Tn FTP -server are displayed to the user. -In addition, -if verbose is on, when a file transfer completes, statistics -regarding the efficiency of the transfer are reported. -By default, -verbose is on. -.It Ic ? Op Ar command -A synonym for help. -.El -.Pp -The following command can be used with ftpsec-aware servers. -.Bl -tag -width Fl -.It Xo -.Ic prot -.Ar clear | -.Ar safe | -.Ar confidential | -.Ar private -.Xc -Set the data protection level to the requested level. -.El -.Pp -The following command can be used with ftp servers that has -implemented the KAUTH site command. -.Bl -tag -width Fl -.It Ic kauth Op Ar principal -Obtain remote tickets. -.El -.Pp -Command arguments which have embedded spaces may be quoted with -quote `"' marks. -.Sh ABORTING A FILE TRANSFER -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 -.Dv ABOR -command to the remote server, and discarding any further data received. -The speed at which this is accomplished depends upon the remote -server's support for -.Dv ABOR -processing. -If the remote server does not support the -.Dv ABOR -command, an -.Ql ftp> -prompt will not appear until the remote server has completed -sending the requested file. -.Pp -The terminal interrupt key sequence will be ignored when -.Nm ftp -has completed 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 -violations of the ftp protocol. -If the delay results from unexpected remote server behavior, the local -.Nm ftp -program must be killed by hand. -.Sh FILE NAMING CONVENTIONS -Files specified as arguments to -.Nm ftp -commands are processed according to the following rules. -.Bl -enum -.It -If the file name -.Sq Fl -is specified, the -.Ar stdin -(for reading) or -.Ar stdout -(for writing) is used. -.It -If the first character of the file name is -.Sq \&| , -the -remainder of the argument is interpreted as a shell command. -.Nm Ftp -then forks a shell, using -.Xr popen 3 -with the argument supplied, and reads (writes) from the stdout -(stdin). -If the shell command includes spaces, the argument -must be quoted; e.g. -\*(Lq" ls -lt"\*(Rq. -A particularly -useful example of this mechanism is: \*(Lqdir more\*(Rq. -.It -Failing the above checks, if ``globbing'' is enabled, -local file names are expanded -according to the rules used in the -.Xr csh 1 ; -c.f. the -.Ic glob -command. -If the -.Nm ftp -command expects a single local file (.e.g. -.Ic put ) , -only the first filename generated by the "globbing" operation is used. -.It -For -.Ic mget -commands and -.Ic get -commands with unspecified local file names, the local filename is -the remote filename, which may be altered by a -.Ic case , -.Ic ntrans , -or -.Ic nmap -setting. -The resulting filename may then be altered if -.Ic runique -is on. -.It -For -.Ic mput -commands and -.Ic put -commands with unspecified remote file names, the remote filename is -the local filename, which may be altered by a -.Ic ntrans -or -.Ic nmap -setting. -The resulting filename may then be altered by the remote server if -.Ic sunique -is on. -.El -.Sh FILE TRANSFER PARAMETERS -The FTP specification specifies many parameters which may -affect a file transfer. -The -.Ic type -may be one of \*(Lqascii\*(Rq, \*(Lqimage\*(Rq (binary), -\*(Lqebcdic\*(Rq, and \*(Lqlocal byte size\*(Rq (for -.Tn PDP Ns -10's -and -.Tn PDP Ns -20's -mostly). -.Nm Ftp -supports the ascii and image types of file transfer, -plus local byte size 8 for -.Ic tenex -mode transfers. -.Pp -.Nm Ftp -supports only the default values for the remaining -file transfer parameters: -.Ic mode , -.Ic form , -and -.Ic struct . -.Sh THE .netrc FILE -The -.Pa .netrc -file contains login and initialization information -used by the auto-login process. -It resides in the user's home directory. -The following tokens are recognized; they may be separated by spaces, -tabs, or new-lines: -.Bl -tag -width password -.It Ic machine Ar name -Identify a remote machine -.Ar name . -The auto-login process searches the -.Pa .netrc -file for a -.Ic machine -token that matches the remote machine specified on the -.Nm ftp -command line or as an -.Ic open -command argument. -Once a match is made, the subsequent -.Pa .netrc -tokens are processed, -stopping when the end of file is reached or another -.Ic machine -or a -.Ic default -token is encountered. -.It Ic default -This is the same as -.Ic machine -.Ar name -except that -.Ic default -matches any name. -There can be only one -.Ic default -token, and it must be after all -.Ic machine -tokens. -This is normally used as: -.Pp -.Dl default login anonymous password user@site -.Pp -thereby giving the user -.Ar automatic -anonymous ftp login to -machines not specified in -.Pa .netrc . -This can be overridden -by using the -.Fl n -flag to disable auto-login. -.It Ic login Ar name -Identify a user on the remote machine. -If this token is present, the auto-login process will initiate -a login using the specified -.Ar name . -.It Ic password Ar string -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 -.Pa .netrc -file for any user other -than -.Ar anonymous , -.Nm ftp -will abort the auto-login process if the -.Pa .netrc -is readable by -anyone besides the user. -.It Ic account Ar string -Supply an additional account password. -If this token is present, 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 -.Dv ACCT -command if it does not. -.It Ic macdef Ar name -Define a macro. -This token functions like the -.Nm ftp -.Ic macdef -command functions. -A macro is defined with the specified name; its contents begin with the -next -.Pa .netrc -line and continue until a null line (consecutive new-line -characters) is encountered. -If a macro named -.Ic init -is defined, it is automatically executed as the last step in the -auto-login process. -.El -.Sh ENVIRONMENT -.Nm Ftp -utilizes the following environment variables. -.Bl -tag -width Fl -.It Ev HOME -For default location of a -.Pa .netrc -file, if one exists. -.It Ev SHELL -For default shell. -.El -.Sh SEE ALSO -.Xr ftpd 8 , -.%T RFC2228 -.Sh HISTORY -The -.Nm ftp -command appeared in -.Bx 4.2 . -.Sh BUGS -Correct execution of many commands depends upon proper behavior -by the remote server. -.Pp -An error in the treatment of carriage returns -in the -.Bx 4.2 -ascii-mode transfer code -has been corrected. -This correction may result in incorrect transfers of binary files -to and from -.Bx 4.2 -servers using the ascii type. -Avoid this problem by using the binary image type. diff --git a/crypto/heimdal/appl/ftp/ftp/ftp.c b/crypto/heimdal/appl/ftp/ftp/ftp.c deleted file mode 100644 index 2e7a9dd2b069c..0000000000000 --- a/crypto/heimdal/appl/ftp/ftp/ftp.c +++ /dev/null @@ -1,1746 +0,0 @@ -/* - * Copyright (c) 1985, 1989, 1993, 1994 - * The Regents of the University of California.
