IP addresses will not -be checked to ensure they match. -.It Fl Fl no-gss-delegate -Disable delegation of GSSAPI credentials. -.It Fl l -Disables command line editing. -.It Fl x -Encrypt command and data channel. -.El -.Pp -The client host with which -.Nm ftp -is to communicate may be specified on the command line. -If this is done, -.Nm ftp -will immediately attempt to establish a connection to an -.Tn FTP -server on that host; otherwise, -.Nm ftp -will enter its command interpreter and await instructions -from the user. -When -.Nm ftp -is awaiting commands from the user the prompt -.Ql ftp\*[Gt] -is provided to the user. -The following commands are recognized -by -.Nm ftp : -.Bl -tag -width Fl -.It Ic \&! 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 \-\-\*[Gt] -.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.

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; for example, most -.Ux -systems will produce -output from the command -.Ql ls \-l . -(See also -.Ic nlist . ) -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 \&ls -output. -If no local file is specified, or if -.Ar local-file -is -.Sq Fl , -the output is sent to the terminal. -.It Ic macdef Ar macro-name -Define a macro. -Subsequent lines are stored as the macro -.Ar macro-name ; -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 until a -.Ic close -command is executed. -The macro processor interprets `$' and `\e' as special characters. -A `$' 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 `\e' followed by any character is replaced by that character. -Use the `\e' to prevent special treatment of the `$'. -.It Ic mdelete Op Ar remote-files -Delete the -.Ar remote-files -on the remote machine. -.It Ic mdir Ar remote-files local-file -Like -.Ic dir , -except multiple remote files may 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 mdir -output. -.It Ic mget Ar remote-files -Expand the -.Ar remote-files -on the remote machine -and do a -.Ic get -for each file name thus produced. -See -.Ic glob -for details on the filename expansion. -Resulting file names will then be processed according to -.Ic case , -.Ic ntrans , -and -.Ic nmap -settings. -Files are transferred into the local working directory, -which can be changed with -.Ql lcd directory ; -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 $1 sed "s/ *$//" \*[Gt] $1' . -Use the `\e' character to prevent special treatment -of the `$','[','[', 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\*[Gt] -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 -uses 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 -.Rs -.%T RFC2228 -.Re -.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/appl/ftp/ftp/ftp.c b/appl/ftp/ftp/ftp.c deleted file mode 100644 index 1cd2f46ebb43..000000000000 --- a/appl/ftp/ftp/ftp.c +++ /dev/null @@ -1,1814 +0,0 @@ -/* - * Copyright (c) 1985, 1989, 1993, 1994 - * The Regents of the University of California.

There is a limit of 16 macros and 4096 total - characters in all defined macros. Macros remain defined - until a cclloossee command is executed. The macro processor - interprets `$' and `\' as special characters. A `$' followed - by a number (or numbers) is replaced by the corresponding - argument on the macro invocation command line. A `$' fol- - lowed by an `i' signals that macro processor that the execut- - ing macro is to be looped. On the first pass `$i' is - replaced by the first argument on the macro invocation com- - mand line, on the second pass it is replaced by the second - argument, and so on. A `\' followed by any character is - replaced by that character. 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.

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 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 - determine 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 - sequence `$0' is replace by the original filename. Addition- - ally, 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 - input filename ".myfile". Spaces may be included in - _o_u_t_p_a_t_t_e_r_n, as in the example: `nmap $1 sed "s/ *$//" > $1' - . Use the `\' character to prevent special treatment of the - `$','[','[', and `,' characters. - - nnttrraannss [_i_n_c_h_a_r_s [_o_u_t_c_h_a_r_s]] - 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 - local 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 - automatically 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 - required 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 - auto-login process, cclloossee will not erase existing macro defi- - nitions, ggeett and mmggeett transfer files from the host on the - primary control connection to the host on the secondary con- - trol 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 trans- - fers depend 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] - Store a local 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 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. - - ppwwdd Print the name of the current working directory on the remote - machine. - - qquuiitt A synonym for bbyyee. - - qquuoottee _a_r_g_1 _a_r_g_2 _._._. - The arguments specified are sent, verbatim, to the remote FTP - server. - - rreeccvv _r_e_m_o_t_e_-_f_i_l_e [_l_o_c_a_l_-_f_i_l_e] - A synonym for get. - - rreeggeett _r_e_m_o_t_e_-_f_i_l_e [_l_o_c_a_l_-_f_i_l_e] - Reget acts like get, except that if _l_o_c_a_l_-_f_i_l_e exists and is - 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] - Request help from the remote FTP server. If a _c_o_m_m_a_n_d_-_n_a_m_e - is specified it is supplied to the server as well. - - rreemmootteessttaattuuss [_f_i_l_e_-_n_a_m_e] - With no arguments, show status of remote machine. If - _f_i_l_e_-_n_a_m_e is specified, show status of _f_i_l_e_-_n_a_m_e on remote - machine. - - rreennaammee [_f_r_o_m] [_t_o] - Rename the file _f_r_o_m on the remote machine, to the file _t_o. - - rreesseett Clear reply queue. This command re-synchronizes com- - mand/reply sequencing with the remote ftp server. Resynchro- - nization may be necessary following a violation of the ftp - protocol by the remote server. - - rreessttaarrtt _m_a_r_k_e_r - Restart the immediately following ggeett or ppuutt at the indicated - _m_a_r_k_e_r. On UNIX systems, marker is usually a byte offset - into the file. - - rrmmddiirr _d_i_r_e_c_t_o_r_y_-_n_a_m_e - Delete a directory on the remote machine. - - 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 - below). The default value is off. - - sseenndd _l_o_c_a_l_-_f_i_l_e [_r_e_m_o_t_e_-_f_i_l_e] - A synonym for put. - - sseennddppoorrtt Toggle the use of PORT commands. By default, ffttpp will - attempt 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 _._._. - The arguments specified are sent, verbatim, to the remote FTP - server as a SITE command. - - ssiizzee _f_i_l_e_-_n_a_m_e - Return size of _f_i_l_e_-_n_a_m_e on remote machine. - - ssttaattuuss Show the current status of ffttpp. - - ssttrruucctt [_s_t_r_u_c_t_-_n_a_m_e] - Set the file transfer _s_t_r_u_c_t_u_r_e to _s_t_r_u_c_t_-_n_a_m_e. By default - ``stream'' structure is used. - - ssuunniiqquuee Toggle storing of files on remote machine under unique file - names. Remote ftp server must support ftp protocol STOU com- - mand for successful completion. The remote server will - report unique name. Default value is off. - - ssyysstteemm Show the type of operating system running on the remote - machine. - - tteenneexx Set the file transfer type to that needed to talk to TENEX - machines. - - ttrraaccee Toggle packet tracing. - - ttyyppee [_t_y_p_e_-_n_a_m_e] - Set the file transfer ttyyppee to _t_y_p_e_-_n_a_m_e. If no type is spec- - ified, the current type is printed. The default type is net- - work ASCII. - - uummaasskk [_n_e_w_m_a_s_k] - 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] - Identify yourself to the remote FTP server. If the _p_a_s_s_w_o_r_d - 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 - regarding the efficiency of the transfer are reported. By - default, verbose is on. - - ?? [_c_o_m_m_a_n_d] - A synonym for help. - - The following command can be used with ftpsec-aware servers. - - pprroott _c_l_e_a_r | _s_a_f_e | _c_o_n_f_i_d_e_n_t_i_a_l | _p_r_i_v_a_t_e - Set the data protection level to the requested level. - - The following command can be used with ftp servers that has implemented - the KAUTH site command. - - kkaauutthh [_p_r_i_n_c_i_p_a_l] - Obtain remote tickets. - - Command arguments which have embedded spaces may be quoted with quote `"' - marks. - -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 - server, and discarding any further data received. The speed at which - this is accomplished depends upon the remote server's support for ABOR - processing. If the remote server does not support the ABOR command, an - `ftp>' prompt will not appear until the remote server has completed send- - ing the requested file. - - The terminal interrupt key sequence will be ignored when ffttpp has com- - pleted 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 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 - example 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 - altered 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 - altered 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 - parameters: 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 machine 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 another 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 - machines 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 - present, 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 - 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 ACCT com- - mand 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. - -EENNVVIIRROONNMMEENNTT - FFttpp uses the following environment variables. - - HOME For default location of a _._n_e_t_r_c file, if one exists. - - SHELL For default shell. - -SSEEEE AALLSSOO - ftpd(8) - - _R_F_C_2_2_2_8. - -HHIISSTTOORRYY - The ffttpp command appeared in 4.2BSD. - -BBUUGGSS - Correct execution of many commands depends upon proper behavior by the - remote server. - - An error in the treatment of carriage returns in the 4.2BSD ascii-mode - transfer code has been corrected. This correction may result in incor- - rect transfers of binary files to and from 4.2BSD servers using the ascii - type. Avoid this problem by using the binary image type. - -4.2 Berkeley Distribution March 23, 2006 4.2 Berkeley Distribution diff --git a/appl/ftp/ftp/ftp_locl.h b/appl/ftp/ftp/ftp_locl.h deleted file mode 100644 index cae845a93ce1..000000000000 --- a/appl/ftp/ftp/ftp_locl.h +++ /dev/null @@ -1,141 +0,0 @@ -/* - * Copyright (c) 1995 - 2001 Kungliga Tekniska Högskolan - * (Royal Institute of Technology, Stockholm, Sweden). - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * - * 1.

The server uses the -.Tn TCP -protocol -and listens at the port specified in the -.Dq ftp -service specification; see -.Xr services 5 . -.Pp -Available options: -.Bl -tag -width Ds -.It Fl a -Select the level of authentication required. Kerberised login can not -be turned off. The default is to only allow kerberised login. Other -possibilities can be turned on by giving a string of comma separated -flags as argument to -.Fl a . -Recognised flags are: -.Bl -tag -width plain -.It Ar plain -Allow logging in with plaintext password. The password can be a(n) OTP -or an ordinary password. -.It Ar otp -Same as -.Ar plain , -but only OTP is allowed. -.It Ar ftp -Allow anonymous login. -.El -.Pp -The following combination modes exists for backwards compatibility: -.Bl -tag -width plain -.It Ar none -Same as -.Ar plain,ftp . -.It Ar safe -Same as -.Ar ftp . -.It Ar user -Ignored. -.El -.It Fl d -Debugging information is written to the syslog using LOG_FTP. -.It Fl g -Anonymous users will get a umask of -.Ar umask . -.It Fl Fl gss-bindings -require the peer to use GSS-API bindings (ie make sure IP addresses match). -.It Fl i -Open a socket and wait for a connection. This is mainly used for -debugging when ftpd isn't started by inetd. -.It Fl l -Each successful and failed -.Xr ftp 1 -session is logged using syslog with a facility of LOG_FTP. -If this option is specified twice, the retrieve (get), store (put), append, -delete, make directory, remove directory and rename operations and -their filename arguments are also logged. -.It Fl p -Use -.Ar port -(a service name or number) instead of the default -.Ar ftp/tcp . -.It Fl T -A client may also request a different timeout period; -the maximum period allowed may be set to -.Ar timeout -seconds with the -.Fl T -option. -The default limit is 2 hours. -.It Fl t -The inactivity timeout period is set to -.Ar timeout -seconds (the default is 15 minutes). -.It Fl u -Set the initial umask to something else than the default 027. -.It Fl U -In previous versions of -.Nm ftpd , -when a passive mode client requested a data connection to the server, the -server would use data ports in the range 1024..4999.

If a STAT command is received during a data transfer, preceded by a - Telnet IP and Synch, transfer status will be returned. - - FFttppdd interprets file names according to the ``globbing'' conventions used - by csh(1). This allows users to use the metacharacters ``*?[]{}~''. - - FFttppdd authenticates users according to these rules. - - 1. If Kerberos authentication is used, the user must pass valid - tickets and the principal must be allowed to login as the - remote user. - - 2. The login name must be in the password data base, and not have - a null password (if Kerberos is used the password field is not - checked). In this case a password must be provided by the - client before any file operations may be performed. If the - user has an OTP key, the response from a successful USER com- - mand will include an OTP challenge. The client may choose to - respond with a PASS command giving either a standard password - or an OTP one-time password. The server will automatically - determine which type of password it has been given and attempt - to authenticate accordingly. See otp(1) for more information - on OTP authentication. - - 3. The login name must not appear in the file _/_e_t_c_/_f_t_p_u_s_e_r_s. - - 4. The user must have a standard shell returned by - getusershell(3). - - 5. If the user name appears in the file _/_e_t_c_/_f_t_p_c_h_r_o_o_t the ses- - sion's root will be changed to the user's login directory by - chroot(2) as for an ``anonymous'' or ``ftp'' account (see next - item). However, the user must still supply a password. This - feature is intended as a compromise between a fully anonymous - account and a fully privileged account. The account should - also be set up as for an anonymous account. - - 6. If the user name is ``anonymous'' or ``ftp'', an anonymous ftp - account must be present in the password file (user ``ftp''). - In this case the user is allowed to log in by specifying any - password (by convention an email address for the user should - be used as the password). - - In the last case, ffttppdd takes special measures to restrict the client's - access privileges. The server performs a chroot(2) to the home directory - of the ``ftp'' user. In order that system security is not breached, it - is recommended that the ``ftp'' subtree be constructed with care, con- - sider following these guidelines for anonymous ftp. - - In general all files should be owned by ``root'', and have non-write per- - missions (644 or 755 depending on the kind of file). No files should be - owned or writable by ``ftp'' (possibly with exception for the - _~_f_t_p_/_i_n_c_o_m_i_n_g, as specified below). - - _~_f_t_p The ``ftp'' homedirectory should be owned by root. - - _~_f_t_p_/_b_i_n The directory for external programs (such as ls(1)). - These programs must either be statically linked, or you - must setup an environment for dynamic linking when run- - ning chrooted. These programs will be used if present: - - ls Used when listing files. - - compress - When retrieving a filename that ends in _._Z, - and that file isn't present, ffttppdd will try - to find the filename without _._Z and com- - press it on the fly. - - gzip Same as compress, just with files ending in - _._g_z. - - gtar Enables retrieval of whole directories as - files ending in _._t_a_r. Can also be combined - with compression. You must use GNU Tar (or - some other that supports the --zz and --ZZ - flags). - - locate Will enable ``fast find'' with the SSIITTEE - FFIINNDD command. You must also create a - _l_o_c_a_t_e_d_b file in _~_f_t_p_/_e_t_c. - - _~_f_t_p_/_e_t_c If you put copies of the passwd(5) and group(5) files - here, ls will be able to produce owner names rather than - numbers. Remember to remove any passwords from these - files. - - The file _m_o_t_d, if present, will be printed after a suc- - cessful login. - - _~_f_t_p_/_d_e_v Put a copy of /dev/null(7) here. - - _~_f_t_p_/_p_u_b Traditional place to put whatever you want to make pub- - lic. - - If you want guests to be able to upload files, create a _~_f_t_p_/_i_n_c_o_m_i_n_g - directory owned by ``root'', and group ``ftp'' with mode 730 (make sure - ``ftp'' is member of group ``ftp''). The following restrictions apply to - anonymous users: - - ++oo Directories created will have mode 700. - - ++oo Uploaded files will be created with an umask of 777, if not changed - with the --gg option. - - ++oo These command are not accessible: DDEELLEE, RRMMDD, RRNNTTOO, RRNNFFRR, SSIITTEE UUMMAASSKK, - and SSIITTEE CCHHMMOODD. - - ++oo Filenames must start with an alpha-numeric character, and consist of - alpha-numeric characters or any of the following: + (plus), - - (minus), = (equal), _ (underscore), .
