sftpg3

sftpg3 — Secure Shell file transfer client - Generation 3

Synopsis

sftpg3 [options...]
[ profile | [user@] host [#port] ]

Description

sftpg3 (sftpg3.exe on Windows) is an FTP-like client that can be used for file transfer over the network. sftpg3 launches ssh-broker-g3 to provide a secure transport using the Secure Shell version 2 protocol. ssh-broker-g3 will ask for passwords or passphrases if they are needed for authentication. sftpg3 uses the configuration specified in the ssh-broker-config.xml file.

However, it should be noted that sftpg3 is not designed to be a drop-in replacement for an FTP client. It is an application that implements the secure file transfer functionality and has most features that common FTP applications have.

To connect to a remote host using sftpg3, give either the name of a connection profile defined in the ssh-broker-config.xml file (profile) or the IP address or DNS name of the remote host, optionally with the remote username and the port of the Secure Shell server ( [user@] host [#port]). If no username is given, the local username is assumed. If no port is given, the default Secure Shell port 22 is assumed. The remote host must be running a Secure Shell version 2 server with the sftp-server subsystem enabled. SSH Tectia Server has sftp-server enabled by default.

When defining a connection profile in the sftpg3 command, notice that SSH Tectia Client deduces the meaning of the argument differently depending on its format. If there is an @ sign in the given attribute value, SSH Tectia Client always interprets it to be <username@hostname>, i.e. not a profile.

Also, if there are dots in a profile name (for example host.x.example.com, the dots need to be escaped on command line. On Unix, enter host\.x\.example\.com, instead. On Windows, enter host˜.x˜.example˜.com, instead. Otherwise the profile name is taken as a host name and the current local user name is used for logging in.

For information on special characters in file names, see the section called “Filename Support”.

Options

The following options are available:

-b buffer_size_bytes

Defines the maximum buffer size for one read/write request (default: 32768 bytes).

-B batch_file

Uses batch mode and executes SFTP commands from batch_file. The file can contain any allowed SFTP commands. For a description of the commands, see the section called “Commands”.

Using batch mode requires that you have previously saved the server host key on the client and set up a non-interactive method for user authentication (for example, host-based authentication or public-key authentication without a passphrase).

-C

Disables compression from the current connection.

+C

Enables zlib compression for this particular connection.

-c, --ciphers=LIST

Sets the allowed ciphers to be offered to the server. List the cipher names in a comma-separated list. For example:

--ciphers seed-cbc@ssh.com,aes256-cbc

Enter help as the value to view the currently supported cipher names.

-D, --debug=LEVEL

Sets the debug level. LEVEL is a number from 0 to 99, where 99 specifies that all debug information should be displayed. This should be the first argument on the command line.

	Note
	Option `-D` only applies on Unix. On Windows, instead of this command-line tool, use the Connection Broker debugging options `-D, -l`.

	Note
	The debug level can be set only when the sftpg3 command starts the Connection Broker. This option has no effect in the command if the Connection Broker is already running.

-i FILE

Defines that private keys defined in the identification file are used for public-key authentication.

-K, --identity-key-file=FILE

Defines that the given key file of a private key or certificate is used in user authentication. The path to the key file is given in the command.

If the file is a private key, it will be read and compared to the keys already known by the Connection Broker key store. If the key is not known, it will be decoded and added to the key store temporarily. If the file is a certificate and Connection Broker knows a matching private key, it will be used. Both the certificate and the private key can be given using multiple -K options on command line.

-N max_requests

Defines the maximum number of read/write requests sent in parallel (default: 10).

-P port

Connects to this Secure Shell port on the remote machine (default: 22).

-v, --verbose

Uses verbose mode (equal to -D 2).

+w, --try-empty-password

Tries an empty password.

--allowed-authentications=METHODS

Defines the only allowed methods that can be used in user authentication. List the methods in a comma-separated list. Enter help as the value to view the currently supported authentication methods.

--compressions=METHODS

Sets the allowed compression methods to be offered to the server. List the methods in a comma-separated list.

Enter help as the value to view the currently supported compression methods.

--exclusive

Defines that a new connection will be opened for each connection attempt, otherwise Connection Broker can reuse recently closed connections.

--fips

Performs the checksums using the FIPS cryptographic library.

--identity=ID

Defines that the ID of the private key is used in user authentication. The ID can be Connection Broker-internal ordinary number of the key, the key hash or the key file name.

--identity-key-hash=ID

Defines the private key used in user authentication with the corresponding public key hash.

--identity-key-id=ID

Defines that the Connection Broker-internal ordinary number of the key is used in user authentication.

--keep-alive=VALUE

Defines how often keep-alive messages are sent to the Secure Shell server. Enter the value as seconds. The default value is 0, meaning that keep-alive messages are disabled.

--macs=LIST

Sets the allowed MACs to be offered to the server. List the MAC names in a comma-separated list. For example:

--mac hmac-sha1-96,hmac-md5,hmac-md5-96

Enter help as the value to view the currently supported MAC names.

--password= PASSWORD | file://PASSWORDFILE | extprog://PROGRAM

Sets the user password or passphrase that the client will send as a response to an authentication method requesting a password or passphrase (hereafter: password). This can be used also with password-protected certificates and public-keys.

The PASSWORD can be given as a path to a file containing the password or as a path to a program or script that outputs the password. It is also possible, but not recommended, to enter the password directly as an argument to this option.

	Caution
Supplying the password on the command line is not a secure option. For example, in a multi-user environment, the password given directly on the command line is trivial to recover from the process table. You should set up a more secure way to authenticate. For non-interactive batch jobs, it is more secure to use public-key authentication without a passphrase, or host-based authentication. At a minimum, use a file or a program to supply the password.

--plugin-path=PATH

Sets plugin path to PATH. This is only used in the FIPS mode.

--tcp-connect-timeout=VALUE

Defines a timeout period (in seconds) for establishing a TCP connection to the Secure Shell server. Enter a timeout value as a positive number. Value 0 (zero) disables this feature and the default system TCP timeout will be used, instead.

-V, --version

Displays program version and exits.

-h, --help

Displays a short summary of command-line options and exits.

Commands

When sftpg3 is ready to accept commands, it will display the prompt sftp>. The user can then enter any of the following commands:

! [command] [arguments]

Invokes an interactive shell on the local machine. if a command is given, it is used as the command to be executed. Optional arguments can be given depending on the command.

append [-u, --unlink-source] [--streaming] [--force-lower-case] [--statistics] [--statistics-format] [--progress-display] [--progress-line-format] [--progress-line-interval] srcfile [dstfile]

Appends the specified local file to the remote file. No globbing can be used.

Options:

-u, --unlink-source

Removes the source file after file transfer.

--streaming [ =yes | no | force | ext ]

Uses streaming in file transfer if the server supports it. Files smaller than buffer_size_bytes are not transferred using streaming. Use force with small files. Default: no

Use ext with z/OS hosts to enable direct MVS dataset access. Use this option only when the file transfer is mainly used for mainframe dataset transfers, as it can slow down the transfer of small files in other environments.

The --streaming=ext option requires also the --checksum=no option, because if checksums are calculated, the file transfer uses staging, which excludes streaming.

An alternative way to activate extended streaming is to define SSH_SFTP_STREAMING_MODE=ext and SSH_SFTP_CHECKSUM_MODE=no as environment variables.

--force-lower-case

Destination filename will be converted to lowercase characters.

The semantics of options --statistics, --statistics-format, --progress-display, --progress-line-format, and --progress-line-interval are the same as with get.

ascii [-s] [remote_nl_conv] [local_nl_conv]

Command ascii sets the transfer mode to ASCII.

For transfers between SSH Tectia on z/OS and other hosts, this also enables automatic ASCII-EBCDIC conversion. Default conversion is between codesets ISO8859-1 and IBM-1047. File is transferred using the LINE format. The site and lsite commands can be used to change the values.

Options:

-s

Only shows the current newline convention. Does not set the transfer mode to ASCII.

remote_nl_conv [local_nl_conv]

Sets hints for the remote and local newline conventions. The local_nl_conv option operates on the local side, but notice that usually the correct local newline convention is already compiled in.

Notice that those options are only hints for the underlying transfer layer, which tries to use the actual newline convention given by the server whenever possible. You can set either of these options to ask, which will cause sftpg3 to prompt you for the newline convention when needed. The available conventions are dos, unix, and mac, using \r\n, \n, and \r as newlines, respectively.

This command does not set the transfer mode to ASCII.

auto

File transfer mode will be selected automatically from the file extension.

binary

Files will be transfered in binary mode.

break

Interrupts batch file execution. Batch file execution can be continued with the continue command.

bye

Quits the application.

cd directory

Changes the current remote working directory.

chmod [-R] [-f] [-v] OCTAL-MODE [file...] , chmod [-R] [-f] [-v] [ugoa] [+-=] [rwxs] [file...]

Sets file permissions of the specified file or files to the bit pattern OCTAL-MODE or changes permissions according to the symbolic mode [ugoa][+-=][rwxs]. Only one symbolic mode combination is supported.

Options:

-R: Recursively changes files and directories.
-f: Uses silent mode (error messages are suppressed).
-v: Uses verbose mode (lists every file processed).

close

Closes the remote connection.

continue

Continues interrupted batch file execution.

debug [ disable | no | debuglevel ]

Disables or enables debug. With disable or no, debugging is disabled. Otherwise, sets debuglevel as debug level string, as per command-line option -D.

digest [-H, --hash] [-o, --offset] [-l, --length] file

Calculates MD5 or SHA-1 digest over file data.

Options:

-H, --hash= [ md5 | sha1 ]: Use md5 or sha1 hash algorithm (default: md5).
-o, --offset=OFFSET: Start reading from file offset OFFSET.
-l, --length=LENGTH: Read LENGTH bytes of file data.

get [-p, --preserve-attributes] [-u, --unlink-source] [-I, --interactive] [--overwrite] [--checksum] [-W, --whole-file] [--checkpoint] [--streaming] [--force-lower-case] [--prefix=] [--statistics] [--statistics-format] [--progress-display] [--progress-line-format] [--progress-line-interval] [--max-depth=] file...

Transfers the specified files from the remote end to the local end. By default, directories are recursively copied with their contents, but this is configurable in the Connection Broker configuration with the SFTP compatibility mode setting (sftpg3-mode in ssh-broker-config.xml). To view the currently set SFTP compatibility mode, run command:

sftp> help get

The currently set compatibility mode is shown in the beginning of the help for command get.

The SFTP compatibility mode options are:

tectia: The sftpg3 client transfers files recursively from the current directory and all its subdirectories.
ftp: The get command is executed as sget meaning that it transfer a single file, and no subdirectories are copied.
openssh: Only regular files and symbolic links from the specified directory are copied, and no subdirectories are copied. Otherwise the semantics of the get command are unchanged.

Options:

-p, --preserve-attributes

Preserves the file permissions and the timestamps when both the source and the destination are on Unix filesystems (including z/OS USS). Preserves the timestamps but not the file permissions, if either one, the source or the destination is on Windows. If the destination is on z/OS MVS, none will be preserved.

-u, --unlink-source

Removes the source file after file transfer. Also directories are removed, if they become empty (move mode).

-I, --interactive

Prompts whether to overwrite an existing destination file (does not work with batch mode).

--overwrite [ =yes | no ]

Decides whether to overwrite existing destination file(s) (default: yes).

--checksum [ =yes | no | md5 | sha1 | md5-force | sha1-force | checkpoint ]

Uses MD5 or SHA-1 checksums or a separate checkpoint database to determine the point in the file where file transfer can be resumed. Files smaller than buffer_size_bytes are not checked. Use md5-force or sha1-force with small files (default: yes, i.e. use MD5 checksums). Use checkpointing when transferring large files one by one.

-W, --whole-file

Does not try incremental checks. By default (if this option is not given), incremental checks are tried. This option can only be used together with the --checksum option.

--checkpoint=s<seconds>

Time interval between checkpoint updates (default: 10 seconds). This option can only be used when --checksum=checkpoint.

--checkpoint=b<bytes>

Byte interval between checkpoint updates (default: 10 MB). This option can only be used when --checksum=checkpoint.

--streaming [ =yes | no | force | ext ]

Uses streaming in file transfer if the server supports it. Files smaller than buffer_size_bytes are not transferred using streaming. Use force with small files. Default: yes

The --streaming=ext option requires also the --checksum=no option, because if checksums are calculated, the file transfer uses staging, which excludes streaming.

An alternative way to activate extended streaming is to define SSH_SFTP_STREAMING_MODE=ext and SSH_SFTP_CHECKSUM_MODE=no as environment variables.

--force-lower-case

Destination filename will be converted to lower case characters.

--max-depth=VALUE

Defines whether directories are copied recursively. The value can be:

0 - unlimited recursion, directories are recursively copied with their contents

1 - copies files from the specified directory only, not from subdirectories

2-n - copies files recursively from the specified number of directory levels. Here n means the system-spesific maximum.

This command line option overrides the recursion depth set in the Connection Broker configuration with element sftpg3-mode and/or the setting made using environment variable SSH_SFTP_CMD_GETPUT_MODE.

--prefix=PREFIX

Adds prefix PREFIX to filename during the file transfer. The prefix is removed after the file has been successfully transferred.

--statistics [ =no | yes | simple | bytes ]

Chooses the style of the statistics to be shown after a file transfer operation. The options mean:

no - no statistics will be created. This is the default.

yes - detailed statistics will be created. You can configure the contents with the statistics-format option. The default statistics contents are:

"Source: %c:%g\r\n"
"Source parameters: %e\r\n"
"Destination: %C:%G\r\n"
"Destination parameters: %E\r\n"
"File size: %s bytes\r\n"

"Start: %xy-%xt-%xd %xh:%xm:%xs\r\n"
"Stop: %Xy-%Xt-%Xd %Xh:%Xm:%Xs\r\n"
"Time: %y\r\n"

simple - simple one-line statistics will be created. You can configure the contents with the statistics-format option. The default statistics contents are:

"Transferred %t bytes, file: '%f' -> '%F'\r\n"

bytes - basic statistics reporting the transferred bytes will be created. You can configure the contents with the statistics-format option. The default statistics contents are:

"Transferred %t bytes, file: '%f' -> '%F'\r\n"

Sets the parameters to be system defaults.

checksum [ =yes | no | md5 | sha1 | md5-force | sha1-force | checkpoint ]

compatibility-mode [ =tectia | ftp | openssh ]

Defines what mode of recursiveness is used in the file transfer:

tectia: The sftpg3 client transfers files recursively from the current directory and all its subdirectories. This is the default mode.
ftp: A single file is transferred, and no subdirectories are copied.
openssh: Only regular files and symbolic links from the specified directory are copied, and no subdirectories are copied.

Chooses the format and contents of the statistics. Use this command when statistics-display=yes|simple|bytes. See the definitions of contents options in command: get --statistics-format

streaming [ =yes | no | force | ext ]

Uses streaming in file transfer if the server supports it. Files smaller than buffer_size_bytes are not transferred using streaming. Use force with small files. Default: no

The streaming=ext option requires also the checksum=no option, because if checksums are calculated, the file transfer uses staging, which excludes streaming.

An alternative way to activate extended streaming is to define SSH_SFTP_STREAMING_MODE=ext and SSH_SFTP_CHECKSUM_MODE=no as environment variables.

setext [extension...]

Sets the file extensions that will be ASCII in the auto transfer mode. Normal zsh-fileglob regexps can be used in the file extensions.

setperm fileperm [:dirperm]

sput [options...] srcfile [dstfile]

Transfers a single specified file from the local end to the remote end under the filename defined with dstfile. Directories are not copied. No wildcards can be used. Options are the same as for get.

sunique [on] [off]

Stores files with unique names. If no option is specified, the command toggles the state of 'sunique'.

In case more than one of the transferred files have the same name, this feature adds a sequencial number to the end of the repeated file name, for example: file.name, file.name1, and file.name2.

symlink targetpath linkpath

Creates symbolic link linkpath, which will point to targetpath.

verbose

Enables verbose mode (identical to the debug 2 command). You may later disable verbose mode by debug disable.

help [topic]

If topic is not given, lists the available topics. If topic is given, outputs available online help about the topic.

helpall

Outputs available online help about all topics.

Command Interpretation

sftpg3 understands both backslashes (\) and quotation marks ("") on the command line. A backslash can be used for ignoring the special meaning of any character in the command-line interpretation. It will be removed even if the character it precedes has no special meaning.

Quotation marks can be used for specifying filenames with spaces.

	Note
	Commands get . and put . will get or put every file in the current directory and possibly they overwrite files in your current directory.

sftpg3 supports wildcard characters (also known as glob patterns) given to commands chmod, lchmod, ls, lls, rm, lrm, get, and put.

Command-Line Editing (Unix)

On Unix, the following key sequences can be used for command-line editing:

Ctrl-Space: Set mark.
Ctrl-A: Go to the beginning of the line.
Ctrl-B: Move the cursor one character to the left.
Ctrl-D: Erase the character to the right of the cursor, or exit the program if the command line is empty.
Ctrl-E: Go to the end of the line.
Ctrl-F: Move the cursor one character to the right.
Ctrl-H: Backspace.
Ctrl-I: Tab.

Filename Support

Different operating systems allow different character sets in filenames. On Unix, some of the special characters are allowed in filenames, but on Windows, the following characters are not allowed:

\/ : * ? " < > |

The sftpg3 command-line tool (both as an interactive and in a batch file) follows the syntax and semantics of Unix shell command-line also on the Windows platform, except that the escape character is ~ (tilde).

When you transfer files that have special characters in the filename (for example unixfilename*?".txt) from a Unix server to Windows, you need to provide the files with new names that are acceptable on Windows.

The sftpg3 command-line client includes two versions of the get command:

The get command can be used to transfer several files at the same time, but it is not possible to define target filenames. Note that if there are special characters in the filenames, you need to rename the files already on Unix so that the names are acceptable also on Windows.

The sget command is used to transfer one file at a time, and it allows you to define a new name for the destination file. Use it to make the name acceptable on Windows. The command sequence is as follows:

$ sftpg3

sftp> open user@server

sftp> sget "file*name.txt" windowsfilename.txt

Escaping special characters

In the sftpg3 command, the following characters have a special meaning, and they need to be escaped in commands that take filenames as arguments:

* asterisk is a wildcard character for any number of any characters

? question mark is a wildcard for any single character

"" quotation marks are placed around strings that are to be taken 'as is'

\ backslash is an escape character on Unix

~ tilde is an escape character on Windows

The escape character tells the sftpg3 command to treat the next character "as is" and not to assume any special meaning for it. The escape character is selected according to the operating system of the local machine.

Note that the \ and ~ characters are special characters themselves, and if they are present in the filename, an escape character must be placed in front of them,too. Therefore, if you need to enter a filename containing \ in Unix or ~ in Windows to any of the sftpg3 commands, add the relevant escape character to it:

\\ on Unix

~~ on Windows

When a filename or part of a filename is placed within the quotation marks "", the sftpg3 command interprets the quoted part 'as is', and none of the characters within the quote are interpreted as wildcards or as any other special characters.

However, on Unix a quotation mark " can also be part of a filename. If you need to enter the " character in a filename, you must add the escape character in front of it both on Unix and on Windows.

For example, to enter a file named file-"name".txt into a command on Windows, enter the following command:

sftp> sget "file-~"name~".txt" filename.txt

See the examples below to learn how the escape characters are used in the SSH Tectia sftpg3 commands, and how to enter filenames with special characters in different operating systems.

Examples of filenames in the sftpg3 commands:

The following filenames are valid in Unix, but they need escape characters in the commands:

file|name.txt
file-"name".txt
file?name.txt
file*name.txt
file\name.txt
file - name.txt
file~name.txt

When using the sftpg3 command-line tool on Unix, enter the above mentioned filenames in the following formats:

file\|name.txt     or  "file|name.txt"
file-\"name\".txt  or  "file-\"name\".txt"
file\?name.txt     or  "file?name.txt"
file\*name.txt     or  "file*name.txt"
file\\name.txt     or  "file\\name.txt"
file\ -\ name.txt  or  "file - name.txt"
file~name.txt      or  "file~name.txt"

Example commands on Unix:

sftp> get "file*name.txt"

sftp> sget "file*name.txt" newfilename.txt

When using the sftpg3 command on Windows, enter the above mentioned Unix filenames in the following formats:

file~|name.txt     or  "file|name.txt"
file-~"name~".txt  or  "file-~"name~".txt"
file~?name.txt     or  "file?name.txt"
file~*name.txt     or  "file*name.txt"
file~\name.txt     or  "file\name.txt"
file~ -~ name.txt  or  "file - name.txt"
file~~name.txt     or  "file~~name.txt"

Example command sequence on Windows:

> sftpg3 open user@server

sftp> get "file name.txt"

sftp> sget "file*name.txt" filename.txt

Environment Variables

sftpg3 uses the following environment variables:

SSH_SFTP_BATCH_FILE=FILE

Defines the path to the batch file to be run when sftpg3 is started. This can be used for example to perform a certain action before an interactive session is started.

Defines the default checksum mode for sftpg3 and scpg3 commands. Checksums are used to determine the point in the file where file transfer can be resumed if it gets interrupted.

no - checksums are not used; the file is always transferred from the beginning until EOF. This prevents staging in z/OS.

md5 – MD5 checksums are used

md5-force – MD5 checksums are forced

sha1 – SHA1 checksums are used

sha1-force – SHA1 checksums are forced

checkpoint – a separate checkpoint database is used.

SSH_SFTP_CMD_GETPUT_MODE=tectia|ftp|openssh

Defines the SFTP compatibility mode for transferring files. This setting affects the behaviour of the get/mget/sget and put/mput/sput commands and the recursion level used by the sftpg3 client. This environment variable overrides the sftpg3-mode setting made in the ssh-broker-config.xml file. The variables are:

tectia – Commands get and put work as usually, while sget and sput allow you to define the destination file name. Directories are copied recursively together with their contents. This is the default mode.

ftp – Commands get/put are executed as sget/sput meaning that they transfer a single file; and commands mget/mput have recursion depth set to 1, meaning that they only transfer files from the specified directory, not from subdirectories.

openssh – Commands get/put/mget/mput behave alike, meaning that only regular files and symbolic links from the specified directory are transferred. No subdirectories are copied.

SSH_SFTP_OVERWRITE=yes|no

If this variable is set to yes (default), the default behavior is to overwrite existing files. If set to no, the default behavior is not to overwrite existing files.

SSH_SFTP_STREAMING_MODE=yes|no|ext

Defines the default streaming mode to be used with sftpg3 and scpg3 commands.

no – streaming is not used.

yes – standard streaming is used.

ext – extended streaming is used.

Exit Values

sftpg3 returns the following values based on the success of the operation:

0     Operation was successful. 
1     Internal error. 
2     Connection aborted by the user.
3     Destination is not a directory, but a directory was specified by the user. 
4     Connecting to the host failed. 
5     Connection lost. 
6     File does not exist. 
7     No permission to access file. 
8     Undetermined error from sshfilexfer.
11    Some non-fatal errors occured during a directory operation.
101   Wrong command-line arguments specified by the user.

In batch mode, sftpg3 returns the value 0 only if no errors occured during the execution. A failure to change the current working directory, a failure to establish a connection, or a connection loss during batch operation cause sftpg3 to abort. Other errors are reported to stderr and the last error value is returned as the exit value of the sftpg3 process.

Examples

Open a sftpg3 session with the remote side connected to the server defined in the connection profile profile1 in the ssh-broker-config.xml file (the local side is intially connected to the local filesystem):

$ sftpg3 profile1

Run sftpg3 in batch mode:

$ sftpg3 -B batch.txt

Example contents of the batch file batch.txt are shown below. Non-interactive authentication methods are used and the server host keys have been stored beforehand:

lopen user@unixserver.example.com
open user@winserver.example.com
binary
lcd backup
cd c:/temp
get --force-lower-case Testfile-X.bin
lchmod 700 testfile-x.bin
quit

The example batch file opens the local side of the connection to a Unix server and the remote side to a Windows server, and sets the transfer mode to binary. It changes to local directory backup and remote directory C:\Temp, and copies a file from the remote directory to the local directory. The filename is changed to lower-case characters (testfile-x.bin). After transfer, the file permissions are changed to allow the user full rights and others no rights.
