SCP Class

Properties   Methods   Events   Config Settings   Errors  

The SCP class can be used to transfer files to and from SSH servers using the Secure Copy Protocol (SCP).

Syntax

SCP

Remarks

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

The SCP class implements a standard SCP 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.

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

Connected Property (SCP Class)

This shows whether the class is connected.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetConnected();
int SetConnected(int bConnected);

Unicode (Windows)
BOOL GetConnected();
INT SetConnected(BOOL bConnected);

int ipworksssh_scp_getconnected(void* lpObj);
int ipworksssh_scp_setconnected(void* lpObj, int bConnected);

bool GetConnected();
int SetConnected(bool bConnected);

Default Value

FALSE

Remarks

This property is used to determine whether or not the class is connected to the remote host.

Note: It is recommended to use the Connect or Disconnect method instead of setting this property.

This property is not available at design time.

Data Type

Boolean

FilePermissions Property (SCP Class)

The file permissions for the RemoteFile .

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetFilePermissions();
int SetFilePermissions(const char* lpszFilePermissions);

Unicode (Windows)
LPWSTR GetFilePermissions();
INT SetFilePermissions(LPCWSTR lpszFilePermissions);

char* ipworksssh_scp_getfilepermissions(void* lpObj);
int ipworksssh_scp_setfilepermissions(void* lpObj, const char* lpszFilePermissions);

QString GetFilePermissions();
int SetFilePermissions(QString qsFilePermissions);

Default Value

"0600"

Remarks

This property defines the permissions that will be assigned to the RemoteFile after an upload. The value is a four digit octal value. This is the same format that is used with the Unix chmod command. The default value of "0600" gives read/write permissions to the file's owner.

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:

Note: Not all servers support setting permissions after an upload.

Default Value

""

Remarks

The LocalFile property is used by the Upload and Download methods. The file will only be overwritten if the Overwrite property is set to True.

Example (Setting LocalFile)

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

Multiple file uploads and downloads are supported through the use of filemasks.

To upload files matching a filemask set LocalFile to a local path including a filemask. Set RemotePath to the directory on the server where the files will be uploaded. In this case RemoteFile is ignored. All matching files will be upload when Upload is called. The StartTransfer, Transfer, and EndTransfer events provide details about the individual file transfers.

To download files matching a filemask set RemoteFile to a filemask. The path may be specified as part of the value in RemoteFile or may be set separately in RemotePath. LocalFile should be set to a local directory where files will be downloaded. When Download is called all matching files are downloaded. The StartTransfer, Transfer, and EndTransfer events provide details about the individual file transfers. In the event an individual file fails to transfer the Error event will fire.

Data Type

String

LocalHost Property (SCP Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost);

Unicode (Windows)
LPWSTR GetLocalHost();
INT SetLocalHost(LPCWSTR lpszLocalHost);

char* ipworksssh_scp_getlocalhost(void* lpObj);
int ipworksssh_scp_setlocalhost(void* lpObj, const char* lpszLocalHost);

QString GetLocalHost();
int SetLocalHost(QString qsLocalHost);

Default Value

""

Remarks

The LocalHost 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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

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 multi-homed 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.

int ipworksssh_scp_getlocalport(void* lpObj);
int ipworksssh_scp_setlocalport(void* lpObj, int iLocalPort);

int GetLocalPort();
int SetLocalPort(int iLocalPort);

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.

LocalPort cannot be changed once a connection is made. Any attempt to set this property when a connection is active will generate an error.

This property is useful when trying to connect to services that require a trusted port in the client side.

Data Type

int GetSSHAuthMode();
int SetSSHAuthMode(int iSSHAuthMode);

Default Value

2

Remarks

The SSH Authentication specification (RFC 4252) specifies multiple methods by which a user can be authenticated by an SSH server. When a call is made to SSHLogon, the class will connect to the SSH server and establish the security layer. After the connection has been secured, the client will send an authentication request to the SSHHost containing the SSHUser. The server will respond containing a list of methods by which that user may be authenticated.

The class will attempt to authenticate the user by one of those methods based on the value of SSHAuthMode and other property values supplied by the user. Currently, the class supports the following authentication methods:

Example (User/Password Auth): Control.SSHAuthMode = SftpSSHAuthModes.amPassword Control.SSHUser = "username" Control.SSHPassword = "password" Control.SSHLogon("server", 22) Example (Public Key Auth): Control.SSHAuthMode = SftpSSHAuthModes.amPublicKey Control.SSHUser = "username" Control.SSHCertStoreType = SSHCertStoreTypes.cstPFXFile; Control.SSHCertStore = "cert.pfx"; Control.SSHCertStorePassword = "certpassword"; Control.SSHCertSubject = "*"; Control.SSHLogon("server", 22)

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The SSHCertStoreType property denotes the type of the certificate store specified by SSHCertStore. If the store is password protected, specify the password in SSHCertStorePassword.

SSHCertStore is used in conjunction with the SSHCertSubject property to specify client certificates. If SSHCertStore has a value, and SSHCertSubject or SSHCertEncoded is set, a search for a certificate is initiated. Please see the SSHCertSubject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

Default Value

"none,zlib"

Remarks

During the SSH handshake, this list will be used to negotiate the compression algorithm to be used between the client and server. This list is used for both directions: client to server and server to client. When negotiating algorithms, each side sends a list of all algorithms it supports or allows. The algorithm chosen for each direction is the first algorithm to appear in the sender's list that the receiver supports, so it is important to list multiple algorithms in preferential order. If no algorithm can be agreed upon, the class will raise an error and the connection will be aborted.

At least one supported algorithm must appear in this list. The following compression algorithms are supported by the class:

• zlib
• zlib@openssh.com
• none

SSHHost Property (SCP Class)

The address of the SSH host.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetSSHHost();
int SetSSHHost(const char* lpszSSHHost);

Unicode (Windows)
LPWSTR GetSSHHost();
INT SetSSHHost(LPCWSTR lpszSSHHost);

int ipworksssh_scp_setsshhost(void* lpObj, const char* lpszSSHHost);

QString GetSSHHost();
int SetSSHHost(QString qsSSHHost);

Default Value

""

Remarks

The SSHHost property specifies the IP address (IP number in dotted internet format) or Domain Name of the remote host. It is set before a connection is attempted and cannot be changed once a connection is established.

If the SSHHost property is set to a Domain Name, a DNS request is initiated, and upon successful termination of the request, the SSHHost property is set to the corresponding address. If the search is not successful, an error is returned.

The SSHHost must be the same host that will be assumed for SSH as for the remote service being connected to.

Data Type

String

SSHPassword Property (SCP Class)

The password for SSH password-based authentication.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetSSHPassword();
int SetSSHPassword(const char* lpszSSHPassword);

Unicode (Windows)
LPWSTR GetSSHPassword();

Data Type

String

SSHPort Property (SCP Class)

The port on the SSH server where the SSH service is running; by default, 22.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetSSHPort();
int SetSSHPort(int iSSHPort);

Unicode (Windows)
INT GetSSHPort();
INT SetSSHPort(INT iSSHPort);

int ipworksssh_scp_getsshport(void* lpObj);
int ipworksssh_scp_setsshport(void* lpObj, int iSSHPort);

int GetSSHPort();
int SetSSHPort(int iSSHPort);

Default Value

22

Remarks

The SSHPort specifies a service port on the SSH host to connect to.

A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error.

Data Type

Integer

SSHUser Property (SCP Class)

The username for SSH authentication.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetSSHUser();
int SetSSHUser(const char* lpszSSHUser);

Unicode (Windows)
LPWSTR GetSSHUser();
INT SetSSHUser(LPCWSTR lpszSSHUser);

char* ipworksssh_scp_getsshuser(void* lpObj);
int ipworksssh_scp_setsshuser(void* lpObj, const char* lpszSSHUser);

QString GetSSHUser();
int SetSSHUser(QString qsSSHUser);

Default Value

""

Remarks

SSHUser specifies the username which is used to authenticate the client to the SSH server. This property is required.

Example (User/Password Auth): Control.SSHAuthMode = SftpSSHAuthModes.amPassword Control.SSHUser = "username" Control.SSHPassword = "password" Control.SSHLogon("server", 22) Example (Public Key Auth): Control.SSHAuthMode = SftpSSHAuthModes.amPublicKey Control.SSHUser = "username" Control.SSHCertStoreType = SSHCertStoreTypes.cstPFXFile; Control.SSHCertStore = "cert.pfx"; Control.SSHCertStorePassword = "certpassword"; Control.SSHCertSubject = "*"; Control.SSHLogon("server", 22)

Data Type

String

Timeout Property (SCP Class)

A timeout for the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout);

Unicode (Windows)
INT GetTimeout();
INT SetTimeout(INT iTimeout);

int ipworksssh_scp_gettimeout(void* lpObj);
int ipworksssh_scp_settimeout(void* lpObj, int iTimeout);

int GetTimeout();
int SetTimeout(int iTimeout);

Default Value

60

Remarks

If the Timeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

If Timeout is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.

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.

Please note that by default, all timeouts are inactivity timeouts, i.e. 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

Config Method (SCP Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworksssh_scp_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

DecodePacket Method (SCP Class)

Decodes a hex-encoded SSH packet.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* DecodePacket(const char* lpszEncodedPacket, int *lpSize = NULL);

Unicode (Windows)
LPSTR DecodePacket(LPCWSTR lpszEncodedPacket, LPINT lpSize = NULL);

char* ipworksssh_scp_decodepacket(void* lpObj, const char* lpszEncodedPacket, int *lpSize);

QByteArray DecodePacket(const QString& qsEncodedPacket);

Remarks

This method is used to decode an SSH packet created by EncodePacket.

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

Error Handling (C++)

This method returns a Binary String value (with length lpSize); after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

DoEvents Method (SCP Class)

Processes events from the internal message queue.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int DoEvents();

Unicode (Windows)
INT DoEvents();

int ipworksssh_scp_doevents(void* lpObj);

int DoEvents();

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Download Method (SCP Class)

Download a RemoteFile from an SCP server.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Download();

Unicode (Windows)
INT Download();

int ipworksssh_scp_download(void* lpObj);

int Download();

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 an absolute or relative path on the server.

If there is no SSH session in place, one is automatically created by the component first.

Example

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

Multiple file uploads and downloads are supported through the use of filemasks.

To upload files matching a filemask set LocalFile to a local path including a filemask. Set RemotePath to the directory on the server where the files will be uploaded. In this case RemoteFile is ignored. All matching files will be upload when Upload is called. The StartTransfer, Transfer, and EndTransfer events provide details about the individual file transfers.

To download files matching a filemask set RemoteFile to a filemask. The path may be specified as part of the value in RemoteFile or may be set separately in RemotePath. LocalFile should be set to a local directory where files will be downloaded. When Download is called all matching files are downloaded. The StartTransfer, Transfer, and EndTransfer events provide details about the individual file transfers. In the event an individual file fails to transfer the Error event will fire.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

EncodePacket Method (SCP Class)

QString EncodePacket(QByteArray qbaPacket);

Remarks

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

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

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

GetSSHParam Method (SCP Class)

LPWSTR GetSSHParam(LPCSTR lpPayload, INT lenPayload, LPCWSTR lpszField);

char* ipworksssh_scp_getsshparam(void* lpObj, const char* lpPayload, int lenPayload, const char* lpszField);

QString GetSSHParam(QByteArray qbaPayload, const QString& qsField);

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 upon 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

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 only applicable for reading and creating SSH packets for use within the SSHCustomAuth event.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SetDownloadStream Method (SCP Class)

Sets the stream to which the downloaded data from the server will be written.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SetDownloadStream(IPWorksSSHStream* sDownloadStream);

Unicode (Windows)
INT SetDownloadStream(IPWorksSSHStream* sDownloadStream);

int ipworksssh_scp_setdownloadstream(void* lpObj, IPWorksSSHStream* sDownloadStream);

int SetDownloadStream(IPWorksSSHStream* sDownloadStream);

Remarks

If a download stream is set before the Download method is called, the downloaded data will be written to the stream. The stream should be open and normally set to position 0.

The class will automatically close this stream if CloseStreamAfterTransfer is true (default). If the stream is closed, you will need to call SetDownloadStream again before calling Download again.

The downloaded content will be written starting at the current position in the stream.

Note: SetDownloadStream and LocalFile will reset the other.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SetSSHParam Method (SCP Class)

QByteArray SetSSHParam(QByteArray qbaPayload, const QString& qsFieldType, const QString& qsFieldValue);

Remarks

This method is used to build the payload portion of an SSH packet to be sent later by a call to SendSSHPacket. Payload should contain the result of a previous call to SetSSHParam. FieldType is a string defining the type of field to be written to the packet. FieldValue should be the string representation of the field to be written.

The following is a list of supported field types and a description of how FieldValue should be encoded:

Note: integer values may be encoded in hexadecimal by prefixing "0x" to the beginning of the string, otherwise the value is assumed to be base-10.

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

Error Handling (C++)

This method returns a Binary String value (with length lpSize); after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

int ipworksssh_scp_setuploadstream(void* lpObj, IPWorksSSHStream* sUploadStream);

int SetUploadStream(IPWorksSSHStream* sUploadStream);

Remarks

If an upload stream is set before the Upload method is called, the content of the stream will be read by the class and uploaded to the server. The stream should be open and normally set to position 0. The class will automatically close this stream if CloseStreamAfterTransfer is true (default). If the stream is closed, you will need to call SetUploadStream again before calling Upload again. The content of the stream will be read from the current position all the way to the end and no bytes will be skipped.

Note: SetUploadStream and LocalFile will reset the other.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.

Please refer to the Error Codes section for more information.

EndTransfer Event (SCP Class)

Fired when a file completes downloading/uploading.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireEndTransfer(SCPEndTransferEventParams *e);

typedef struct {
  int Direction;
  const char *LocalFile;
  const char *RemoteFile;
  const char *RemotePath;
  int reserved;
} SCPEndTransferEventParams;


Unicode (Windows)
virtual INT FireEndTransfer(SCPEndTransferEventParams *e);

typedef struct {
  INT Direction;
  LPCWSTR LocalFile;
  LPCWSTR RemoteFile;
  LPCWSTR RemotePath;
  INT reserved;
} SCPEndTransferEventParams;

#define EID_SCP_ENDTRANSFER 4

virtual INT IPWORKSSSH_CALL FireEndTransfer(INT &iDirection, LPSTR &lpszLocalFile, LPSTR &lpszRemoteFile, LPSTR &lpszRemotePath);

class SCPEndTransferEventParams {
public:
  int Direction();

  const QString &LocalFile();

  const QString &RemoteFile();

  const QString &RemotePath();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void EndTransfer(SCPEndTransferEventParams *e);

// Or, subclass SCP and override this emitter function.
virtual int FireEndTransfer(SCPEndTransferEventParams *e) {...}

Remarks

The EndTransfer event fires when either an upload or a download operation completes. This is when the file finishes transferring and/or a directory listing is finished.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The LocalFile, RemoteFile, and RemotePath parameters provide information about the current transfer.

Error Event (SCP Class)

Information about errors during data delivery.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireError(SCPErrorEventParams *e);

typedef struct {
  int ErrorCode;
  const char *Description;
  const char *LocalFile;
  const char *RemoteFile;
  const char *RemotePath;
  int reserved;
} SCPErrorEventParams;


Unicode (Windows)
virtual INT FireError(SCPErrorEventParams *e);

typedef struct {
  INT ErrorCode;
  LPCWSTR Description;
  LPCWSTR LocalFile;
  LPCWSTR RemoteFile;
  LPCWSTR RemotePath;
  INT reserved;
} SCPErrorEventParams;

#define EID_SCP_ERROR 5

virtual INT IPWORKSSSH_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription, LPSTR &lpszLocalFile, LPSTR &lpszRemoteFile, LPSTR &lpszRemotePath);

class SCPErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  const QString &LocalFile();

  const QString &RemoteFile();

  const QString &RemotePath();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Error(SCPErrorEventParams *e);

// Or, subclass SCP and override this emitter function.
virtual int FireError(SCPErrorEventParams *e) {...}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

The LocalFile, RemoteFile, and RemotePath parameters provide information about the current transfer.

Log Event (SCP Class)

Fires once for each log message.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireLog(SCPLogEventParams *e);

typedef struct {
  int LogLevel;
  const char *Message;
  const char *LogType;
  int reserved;
} SCPLogEventParams;


Unicode (Windows)
virtual INT FireLog(SCPLogEventParams *e);

typedef struct {
  INT LogLevel;
  LPCWSTR Message;
  LPCWSTR LogType;
  INT reserved;
} SCPLogEventParams;

#define EID_SCP_LOG 6

virtual INT IPWORKSSSH_CALL FireLog(INT &iLogLevel, LPSTR &lpszMessage, LPSTR &lpszLogType);

class SCPLogEventParams {
public:
  int LogLevel();

  const QString &Message();

  const QString &LogType();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Log(SCPLogEventParams *e);

// Or, subclass SCP and override this emitter function.
virtual int FireLog(SCPLogEventParams *e) {...}

Remarks

This event fires once for each log messages generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the detail level of the message. Possible values are:

Message is the log message.

LogType is reserved for future use.

SSHCustomAuth Event (SCP Class)

Fired when the class is doing custom authentication.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSHCustomAuth(SCPSSHCustomAuthEventParams *e);

typedef struct {
  char *Packet;
  int reserved;
} SCPSSHCustomAuthEventParams;


Unicode (Windows)
virtual INT FireSSHCustomAuth(SCPSSHCustomAuthEventParams *e);

typedef struct {
  LPWSTR Packet;
  INT reserved;
} SCPSSHCustomAuthEventParams;

#define EID_SCP_SSHCUSTOMAUTH 7

virtual INT IPWORKSSSH_CALL FireSSHCustomAuth(LPSTR &lpszPacket);

class SCPSSHCustomAuthEventParams {
public:
  const QString &Packet();
  void SetPacket(const QString &qsPacket);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSHCustomAuth(SCPSSHCustomAuthEventParams *e);

// Or, subclass SCP and override this emitter function.
virtual int FireSSHCustomAuth(SCPSSHCustomAuthEventParams *e) {...}

Remarks

SSHCustomAuth is fired during the user authentication stage of the SSH logon process if SSHAuthMode is set to amCustom. Packet contains the raw last 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 (SCP Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSHKeyboardInteractive(SCPSSHKeyboardInteractiveEventParams *e);

typedef struct {
  const char *Name;
  const char *Instructions;
  const char *Prompt;
  char *Response;
  int EchoResponse;
  int reserved;
} SCPSSHKeyboardInteractiveEventParams;


Unicode (Windows)
virtual INT FireSSHKeyboardInteractive(SCPSSHKeyboardInteractiveEventParams *e);

typedef struct {
  LPCWSTR Name;
  LPCWSTR Instructions;
  LPCWSTR Prompt;
  LPWSTR Response;
  BOOL EchoResponse;
  INT reserved;
} SCPSSHKeyboardInteractiveEventParams;

#define EID_SCP_SSHKEYBOARDINTERACTIVE 8

virtual INT IPWORKSSSH_CALL FireSSHKeyboardInteractive(LPSTR &lpszName, LPSTR &lpszInstructions, LPSTR &lpszPrompt, LPSTR &lpszResponse, BOOL &bEchoResponse);

class SCPSSHKeyboardInteractiveEventParams {
public:
  const QString &Name();

  const QString &Instructions();

  const QString &Prompt();

  const QString &Response();
  void SetResponse(const QString &qsResponse);

  bool EchoResponse();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSHKeyboardInteractive(SCPSSHKeyboardInteractiveEventParams *e);

// Or, subclass SCP and override this emitter function.
virtual int FireSSHKeyboardInteractive(SCPSSHKeyboardInteractiveEventParams *e) {...}

Remarks

SSHKeyboardInteractive is fired during the user authentication stage of the 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 (SCP Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSHServerAuthentication(SCPSSHServerAuthenticationEventParams *e);

typedef struct {
  const char *HostKey;
  int lenHostKey;
  const char *Fingerprint;
  const char *KeyAlgorithm;
  const char *CertSubject;
  const char *CertIssuer;
  const char *Status;
  int Accept;
  int reserved;
} SCPSSHServerAuthenticationEventParams;


Unicode (Windows)
virtual INT FireSSHServerAuthentication(SCPSSHServerAuthenticationEventParams *e);

typedef struct {
  LPCSTR HostKey;
  INT lenHostKey;
  LPCWSTR Fingerprint;
  LPCWSTR KeyAlgorithm;
  LPCWSTR CertSubject;
  LPCWSTR CertIssuer;
  LPCWSTR Status;
  BOOL Accept;
  INT reserved;
} SCPSSHServerAuthenticationEventParams;

#define EID_SCP_SSHSERVERAUTHENTICATION 9

virtual INT IPWORKSSSH_CALL FireSSHServerAuthentication(LPSTR &lpHostKey, INT &lenHostKey, LPSTR &lpszFingerprint, LPSTR &lpszKeyAlgorithm, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);

class SCPSSHServerAuthenticationEventParams {
public:
  const QByteArray &HostKey();

  const QString &Fingerprint();

  const QString &KeyAlgorithm();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSHServerAuthentication(SCPSSHServerAuthenticationEventParams *e);

// Or, subclass SCP and override this emitter function.
virtual int FireSSHServerAuthentication(SCPSSHServerAuthenticationEventParams *e) {...}

Remarks

This event is where the client can decide whether to continue with the connection process or not. If the public key is known to be a valid key for the 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 that 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. Supported values are:

• 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 only applicable when KeyAlgorithm is "x509v3-sign-rsa" or "x509v3-sign-dss".

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

Status is reserved for future use.

SSHStatus Event (SCP Class)

Shows the progress of the secure connection.
