Remarks

The SFTPClient class is the Secure Shell (SSH)-enabled equivalent of the IPWorks FTP class. The SSHHost and SSHPort properties specify which Secure Shell (SSH) server to use. The SSHUser and SSHPassword properties allow the client to authenticate itself with the server. The SSHServerAuthentication event or SSHAcceptServerHostKey property allow you to check the server identity. Finally, the SSHStatus event provides information about the SSH handshake.

The SFTPClient class implements a standard SSH file transfer client.

The first step in using the class is specifying the SSHHost, SSHUser, and SSHPassword. The file to upload to or download from is given by the RemoteFile property. The file to download to or upload from is specified by LocalFile. The current path in the server is specified by the RemotePath property.

If LocalFile is set to something other than an empty string, then files are received in LocalFile; otherwise, the data are received through the Transfer event. StartTransfer and EndTransfer are fired at the beginning and end of transmission.

Directory listings are received through the DirList event.

ipworkssftp_sftpclient_get($res, 27 );
ipworkssftp_sftpclient_set($res, 27, $value );

Default Value

0

Remarks

Includes a 32-bit integer containing the a POSIX-compatible file permission bitmask.

The bitmask should be interpreted as a decimal value of a series of octal digits. For example, an octal permission value of "100644" would be "33188" in Base10, and "40755" in octal would be "16877" in Base10.

The last three octal digits are the most significant and represent, in order, the file access capabilities of the file's owner, the owner's group, and other users. Each of these octal digits is, on its own, a 3-bit bitmask with the following possible values:

An octal permission digit of 7 would have all three values set and would mean that the file can be read, written, and executed by that user class. For example, the octal permissions "100644" would have a value "6" for the owner, "4" for the group, and "4" for other users. This would be interpreted to mean that all users can read the file, no users can execute it, and only the owner can write it. The permissions "40755" would mean that all users can read and execute the file, but only the owner can write it.

The previous octal digit is another bitmask with the following values:

The previous two octal digits are used together as a bitmask to determine the type of file. This bitmask has the following values:

For example, the octal file permissions "100644" would indicate a regular file and octal "40755" would indicate a directory.

Note: You will need to convert the octal permissions bitmask into its decimal representation.

This property is not available at design time.

LocalHost Property (IPWorksSFTP_SFTPClient Class)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Object Oriented Interface

public function getLocalHost();
public function setLocalHost($value);

Procedural Interface

ipworkssftp_sftpclient_get($res, 40 );
ipworkssftp_sftpclient_set($res, 40, $value );

Default Value

''

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

Data Type

String

LocalPort Property (IPWorksSFTP_SFTPClient Class)

Object Oriented Interface

public function getLocalPort();
public function setLocalPort($value);

Procedural Interface

ipworkssftp_sftpclient_get($res, 41 );
ipworkssftp_sftpclient_set($res, 41, $value );

Default Value

0

Remarks

This property must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this property to 0 (default) enables the system to choose an open port at random. The chosen port will be returned by the LocalPort property after the connection is established.

Procedural Interface

ipworkssftp_sftpclient_get($res, 106 );
ipworkssftp_sftpclient_set($res, 106, $value );

Default Value

0

Remarks

The StartByte property is used by the Upload and Download methods to determine at what offset to begin the transfer. This allows for resuming both uploads and downloads. The value of this property is reset to 0 after a successful transfer. StartByte is not valid for use with Append.

When downloading, this property can be used in conjunction with the TransferredDataLimit configuration setting to download only a specific range of data from the current RemoteFile.

Data Type

Long64

Timeout Property (IPWorksSFTP_SFTPClient Class)

The timeout for the class.

Object Oriented Interface

public function getTimeout();
public function setTimeout($value);

Procedural Interface

ipworkssftp_sftpclient_get($res, 107 );
ipworkssftp_sftpclient_set($res, 107, $value );

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the class fails with an error.

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

Data Type

Integer

Append Method (IPWorksSFTP_SFTPClient Class)

Append data from LocalFile to a remote file RemoteFile on a Secure File Transfer Protocol (SFTP) server.

Object Oriented Interface

public function doAppend();

Procedural Interface

ipworkssftp_sftpclient_do_append($res);

Remarks

This method is similar to the Upload method, but the local file specified by LocalFile is appended to RemoteFile on the server as opposed to replacing it as with the Upload method. RemoteFile is either an absolute path on the server, or a path relative to RemotePath. The server will create a file with that name if it does not already exist (similar to upload).

If a Secure Shell (SSH) session is not in place, one is automatically created by the component first.

ChangeRemotePath Method (IPWorksSFTP_SFTPClient Class)

Changes the current path on the server.

Object Oriented Interface

public function doChangeRemotePath($remotepath);

Procedural Interface

ipworkssftp_sftpclient_do_changeremotepath($res, $remotepath);

Remarks

This method changes the current path on the server to the specified RemotePath. When called, the class will issue a command to the server to change the directory. The RemotePath parameter may hold an absolute or relative path.

Absolute Paths

If the path begins with a /, it is considered an absolute path and must specify the entire path from the root of the server. For example:

component.ChangeRemotePath("/home/testuser/myfolder");

Relative Paths

If the path does not begin with a /, it is considered a relative path and is resolved in relation to the current directory. For instance, a value of myfolder will indicate a subfolder of the current directory. The special value .. refers to the parent directory of the current path. For example:

//Change to the 'myfolder' sub-directory component.ChangeRemotePath("myfolder"); //Navigate up two levels and then into the 'another/folder' path. component.ChangeRemotePath("../../another/folder");

CheckFileExists Method (IPWorksSFTP_SFTPClient Class)

Returns if the file specified by RemoteFile exists on the remote server.

Object Oriented Interface

public function doCheckFileExists();

Procedural Interface

ipworkssftp_sftpclient_do_checkfileexists($res);

Remarks

This property returns true if the file exists on the remote server. It returns false if the file does not exist. You must specify the file you wish to check by setting the RemoteFile before calling this method.

If no session is in place, the value of this property will always be false.

Config Method (IPWorksSFTP_SFTPClient Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

ipworkssftp_sftpclient_do_config($res, $configurationstring);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Connect Method (IPWorksSFTP_SFTPClient Class)

Connects to the Secure Shell (SSH) host without logging in.

Object Oriented Interface

public function doConnect();

Procedural Interface

ipworkssftp_sftpclient_do_connect($res);

Remarks

This method establishes a connection with the SSHHost but does not log in. In most cases, it is recommended to use the SSHLogon method, which will both establish a connection and log in to the server.

This method may be useful in cases in which it is desirable to separate the connection and logon operations--for instance, confirming a host is available by first creating the connection.

CreateFile Method (IPWorksSFTP_SFTPClient Class)

Creates a file on the Secure File Transfer Protocol (SFTP) server.

Object Oriented Interface

public function doCreateFile($filename);

Procedural Interface

ipworkssftp_sftpclient_do_createfile($res, $filename);

Remarks

This method creates an empty file on the server with the name specified by the FileName parameter.

To upload a file with content, use Upload instead.

DecodePacket Method (IPWorksSFTP_SFTPClient Class)

Delete a file specified by FileName from a Secure File Transfer Protocol (SFTP) server.

Object Oriented Interface

public function doDeleteFile($filename);

Procedural Interface

ipworkssftp_sftpclient_do_deletefile($res, $filename);

Remarks

The remote file or directory specified by FileName is deleted. FileName is either an absolute path on the server or a path relative to RemotePath.

If a Secure Shell (SSH) session is not in place, one is automatically created by the component first.

Disconnect Method (IPWorksSFTP_SFTPClient Class)

Disconnects from the server without first logging off.

Object Oriented Interface

public function doDisconnect();

Procedural Interface

ipworkssftp_sftpclient_do_disconnect($res);

Remarks

This method immediately disconnects from the server without first logging off.

In most cases, the SSHLogoff method should be used to log off and disconnect from the server. Call the Disconnect method in cases in which it is desirable to immediately disconnect without first logging off.

DoEvents Method (IPWorksSFTP_SFTPClient Class)

This method processes events from the internal message queue.

Object Oriented Interface

public function doEvents();

Procedural Interface

ipworkssftp_sftpclient_do_doevents($res);

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Download Method (IPWorksSFTP_SFTPClient Class)

Download a RemoteFile from a Secure File Transfer Protocol (SFTP) server.

Object Oriented Interface

public function doDownload();

Procedural Interface

ipworkssftp_sftpclient_do_download($res);

Remarks

The remote file specified by RemoteFile is downloaded to the local file specified by LocalFile, or it is retrieved through the Transfer event, if the LocalFile property is "" (empty string). RemoteFile is either an absolute path on the server or is a path relative to RemotePath.

If a Secure Shell (SSH) session is not in place, one is automatically created by the component first.

Example. Download a File:

SFTPControl.Localfile = "C:\localfile.txt" SFTPControl.RemoteFile = "remotefile.txt" SFTPControl.Download() SFTPControl.Localfile = "C:\localfile2.txt" SFTPControl.RemoteFile = "folder/remotefile2.txt" SFTPControl.Download()

DownloadRange Method (IPWorksSFTP_SFTPClient Class)

DownloadRange facilitates the partial downloading of a remote file from a Secure File Transfer Protocol (SFTP) server.

Object Oriented Interface

public function doDownloadRange($path, $filename, $startbyte, $count, $buffer);

Procedural Interface

ipworkssftp_sftpclient_do_downloadrange($res, $path, $filename, $startbyte, $count, $buffer);

Remarks

This method enables downloading a specific segment of a remote file specified by Path and FileName. StartByte is the offset (in bytes) relative to the beginning of the file from where to start reading, and Count is the number of bytes to read into the specified Buffer.

This functionality is particularly useful for efficient management of large files and targeted data retrieval within them.

Note: If the requested range extends beyond the end of the file, only the available bytes will be returned.

EncodePacket Method (IPWorksSFTP_SFTPClient Class)

Hex encodes a Secure Shell (SSH) packet.

Object Oriented Interface

public function doEncodePacket($packet);

Procedural Interface

ipworkssftp_sftpclient_do_encodepacket($res, $packet);

Remarks

This method is used to encode a raw SSH packet created by SetSSHParam.

Note: This method is applicable only for reading and creating Secure Shell (SSH) packets for use within the SSHCustomAuth event.

GetSSHParam Method (IPWorksSFTP_SFTPClient Class)

Reads a field from a Secure Shell (SSH) packet's payload.

Object Oriented Interface

public function doGetSSHParam($payload, $field);

Procedural Interface

ipworkssftp_sftpclient_do_getsshparam($res, $payload, $field);

Remarks

This method is used to read the value of a particular field from an SSH packet's payload. Payload should contain the full payload of a packet received by an event such as SSHChannelRequest. Field is the name of a field to be read out of the packet.

The following is a list of the names of well-known channel request field names and their encodings:

The remaining fields that are available in the payload are dependent on the value of RequestType.

pty-req

Pty-req is a request to open a pseudo terminal on the specified channel. The following fields are available:

x11-req

X11-req is a request to forward x11 sessions over a channel. The following fields are available:

env

Env is a request to set an environment variable to be passed into a shell that may be started later. The following fields are available:

exec

Exec is a request to execute a command on the channel using the authenticated user's shell. The following field is available:

subsystem

Subsystem is a request to start a subsystem on the specified channel. The following field is available:

xon-xoff

Xon-xoff instructs the server to allow or disallow control-S/control-Q style flow control. The following field is available:

signal

Sends a signal to the remote process/service. The following field is available:

If the packet type is not well known, Field should start with the special character "%" and contain a comma-separated list of field types as defined in SetSSHParam. For example, reading out the X11AuthProtocol of an x11-req payload, you can use "%s,f".

Note: The return value is a string encoded the same way as the FieldValue param in SetSSHParam.

Note: This method is applicable only for reading and creating Secure Shell (SSH) packets for use within the SSHCustomAuth event.

GetSSHParamBytes Method (IPWorksSFTP_SFTPClient Class)

Reads a field from a Secure Shell (SSH) packet's payload.

Object Oriented Interface

public function doGetSSHParamBytes($payload, $field);

Procedural Interface

ipworkssftp_sftpclient_do_getsshparambytes($res, $payload, $field);

Remarks

This method is the same as calling GetSSHParam, but it returns raw bytes instead of strings.

Note: This method is applicable only for reading and creating Secure Shell (SSH) packets for use within the SSHCustomAuth event.

Interrupt Method (IPWorksSFTP_SFTPClient Class)

This method interrupts the current method.

Object Oriented Interface

public function doInterrupt();

Procedural Interface

ipworkssftp_sftpclient_do_interrupt($res);

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ListDirectory Method (IPWorksSFTP_SFTPClient Class)

List the current directory specified by RemotePath on a Secure File Transfer Protocol (SFTP) server.

Object Oriented Interface

public function doListDirectory();

Procedural Interface

ipworkssftp_sftpclient_do_listdirectory($res);

Remarks

A listing is requested for the directory (or file mask) specified in RemoteFile. RemoteFile is either an absolute path on the server or is a path relative to RemotePath. The file listing is received through the DirList event.

If a Secure Shell (SSH) session is not in place, one is automatically created by the component first.

MakeDirectory Method (IPWorksSFTP_SFTPClient Class)

Creates a directory on a Secure File Transfer Protocol (SFTP) server.

Object Oriented Interface

public function doMakeDirectory($newdir);

Procedural Interface

ipworkssftp_sftpclient_do_makedirectory($res, $newdir);

Remarks

A directory with a path specified by NewDir is created on the SFTP server. NewDir is either an absolute path on the server or is a path relative to RemotePath.

If a Secure Shell (SSH) session is not in place, one is automatically created by the component first.

QueryFileAttributes Method (IPWorksSFTP_SFTPClient Class)

Queries the server for the attributes of RemoteFile .

Object Oriented Interface

public function doQueryFileAttributes();

Procedural Interface

ipworkssftp_sftpclient_do_queryfileattributes($res);

Remarks

This method queries the server for attributes of RemoteFile. After calling this method, FileAttributes will be populated with the values returned by the server.

To update attributes, modify the desired values in FileAttributes and call UpdateFileAttributes.

QueueFile Method (IPWorksSFTP_SFTPClient Class)

Adds a file to the transfer queue.

Object Oriented Interface

public function doQueueFile($localfile, $remotefile);

Procedural Interface

ipworkssftp_sftpclient_do_queuefile($res, $localfile, $remotefile);

Remarks

This method adds a file to the queue of files that will be transferred.

It is not required to use this method; however, this method extends the ability of the class to allow for multiple simultaneous file transfers.

To simply transfer a file without using this method, you need only to set LocalFile and RemoteFile and to call Upload or Download, as appropriate. This method allows you to instead queue multiple files before beginning a transfer.

When a file is queued, it will not be transferred until the Upload or Download method is called. If multiple files are queued, the files will be transferred simultaneously. The SimultaneousTransferLimit setting controls the maximum number of simultaneous transfers.

The Upload or Download method will not return until the queue has been completely processed. This method may be called from within events to add additional files to the queue before processing is complete.

To clear the queue, call ResetQueue. This will not affect current transfers.

To cancel an individual file transfer, set the Cancel parameter of the Transfer event to True. The rest of the queue will continue to process as normal.

The Interrupt method may be called to immediately stop all current transfers.

In the event of a file-specific error, the Error event will fire and the LocalFile and RemoteFile event parameters can be used to identify the file to which the error applies.

RemoveDirectory Method (IPWorksSFTP_SFTPClient Class)

Remove a directory specified by DirName from a secure file transfer protocol (SFTP) server.

Object Oriented Interface

public function doRemoveDirectory($dirname);

Procedural Interface

public function fireSSHCustomAuth($param);

Procedural Interface

ipworkssftp_sftpclient_register_callback($res, 8, array($this, 'fireSSHCustomAuth'));

Parameter List

 'packet'

Remarks

SSHCustomAuth is fired during the user authentication stage of the Secure Shell (SSH) logon process if SSHAuthMode is set to amCustom. Packet contains the last raw SSH packet sent by the server, in HEX-encoded format.

The client should create a new raw SSH packet to send to the server and set Packet to the HEX-encoded representation of the packet to send.

In all cases, Packet will start with the message type field.

To read the incoming packet, call DecodePacket and then use the GetSSHParam and GetSSHParamBytes methods. To create a packet, use the SetSSHParam method and then call EncodePacket to obtain a HEX-encoded value and assign this to the Packet parameter.

SSHKeyboardInteractive Event (IPWorksSFTP_SFTPClient Class)

Fired when the class receives a request for user input from the server.

Object Oriented Interface

public function fireSSHKeyboardInteractive($param);

Procedural Interface

ipworkssftp_sftpclient_register_callback($res, 9, array($this, 'fireSSHKeyboardInteractive'));

Parameter List

 'name'
 'instructions'
 'prompt'
 'response'
 'echoresponse'

Remarks

SSHKeyboardInteractive is fired during the user authentication stage of the Secure Shell (SSH) logon process. During authentication, the class will request a list of available authentication methods for the SSHUser. For example, if the SSHHost responds with "keyboard-interactive", the class will fire this event to allow the client application to set the password.

During authentication, the SSH server may respond with a request for the user's authentication information. Name is a server-provided value associated with the authentication method such as "CRYPTOCard Authentication". Instructions will contain specific instructions, also supplied by the server, for how the user should respond.

Along with these values, the server will also send at least one input Prompt to be displayed to and filled out by the user. Response should be set to the user's input, and will be sent back in the user authentication information response. EchoResponse is a server recommendation for whether or not the user's response should be echoed back during input.

Note: The server may send several prompts in a single packet. The class will fire the SSHKeyboardInteractive event once for each prompt.

SSHServerAuthentication Event (IPWorksSFTP_SFTPClient Class)

Fired after the server presents its public key to the client.

Object Oriented Interface

public function fireSSHServerAuthentication($param);

Procedural Interface

ipworkssftp_sftpclient_register_callback($res, 10, array($this, 'fireSSHServerAuthentication'));

Parameter List

 'hostkey'
 'fingerprint'
 'keyalgorithm'
 'certsubject'
 'certissuer'
 'status'
 'accept'

Remarks

This event is fired when the client can decide whether or not to continue with the connection process. If the public key is known to be a valid key for the Secure Shell (SSH) server, Accept should be set to True within the event. Otherwise, the server will not be authenticated and the connection will be broken.

Accept will be True only if either HostKey or Fingerprint is identical to the value of SSHAcceptServerHostKey.

Accept may be set to True manually to accept the server host key.

Note: SSH's security inherently relies on client verification of the host key. Ignoring the host key and always setting Accept to True is strongly discouraged, and could cause potentially serious security vulnerabilities in your application. It is recommended that clients maintain a list of known keys for each server and check HostKey against this list each time a connection is attempted.

Host Key contains the full binary text of the key, in the same format used internally by SSH.

Fingerprint holds the SHA-256 hash of HostKey in the hex-encoded form: 0a:1b:2c:3d. To configure the hash algorithm used to calculate this value, see SSHFingerprintHashAlgorithm.

KeyAlgorithm identifies the host key algorithm. The following values are supported:

• ssh-rsa
• ssh-dss
• rsa-sha2-256
• rsa-sha2-512
• x509v3-sign-rsa
• x509v3-sign-dss
• ecdsa-sha2-nistp256
• ecdsa-sha2-nistp384
• ecdsa-sha2-nistp521

CertSubject is the subject of the certificate. This is applicable only when KeyAlgorithm is "x509v3-sign-rsa" or "x509v3-sign-dss".

CertIssuer is the issuer of the certificate. This is applicable only when KeyAlgorithm is "x509v3-sign-rsa" or "x509v3-sign-dss".

Status is reserved for future use.
