SSHPlex Component

Properties   Methods   Events   Config Settings   Errors  

SSHPlex is a multiplexed class that operates over a single Secure Shell (SSH) connection and allows file transfers using Secure File Transfer Protocol (SFTP) or Secure Copy Protocol (SCP). It can remotely execute commands using SExec or SShell.

Syntax

ipworksssh.SSHPlex

Remarks

The SSHPlex component combines the functionality of the Secure Copy Protocol (SCP) component, the Secure File Transfer Protocol (SFTP) component, the SExec component, and the SShell component. All operations are performed over a single Secure Shell (SSH) connection.

The asynchronous design of the component allows multiple operations to be performed simultaneously. For example, several SFTP file transfers may be started, and while the files are still transferring, commands may be executed over SExec. This is accomplished through the use of operation Ids to track ongoing and complete operations, and ChannelType, which allows switching between SFTP, SCP, SExec, and SShell usage.

After establishing a connection, set ChannelType to the desired protocol and set any relevant properties for the operation. Calling the desired method will return an operation Id (string) that identifies the operation in progress. A corresponding SSHPlexOperation will also be added to the Operations collection.

When the operation completes, a corresponding event will fire indicating the success or failure of the operation. Examine the event parameters for further details. For instance, after calling Upload, the UploadComplete event will fire.

Ongoing operations may be canceled at any time by passing the operation Id to the CancelOperation method.

NOTE: The DoEvents method must be called frequently to process outstanding events. This is particularly important for SCP and SFTP operations. Call DoEvents in a loop for best results.

Authentication

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.

Example. Logging On:

SSHPlexControl.SSHUser = "username" SSHPlexControl.SSHPassword = "password" SSHPlexControl.SSHLogon("sshHost", sshPort)

Channel Types

The ChannelType property determines the protocol used by the component and therefore the applicable methods and properties for each channel. Valid values are as follows:
ChannelTypeDescriptionApplicable MethodsApplicable Properties
0 (cstSShell - default) An interactive shell for command execution
1 (cstSExec) Command execution using SExec
2 (cstScp) SCP File Transfer
3 (cstSftp) SFTP File Transfer

NOTE: CancelOperation and other methods not explicitly listed here are applicable to all channel types.

Listing Files and Folders

ListDirectory lists files and folders from the path specified by RemotePath.

The directory entries are provided through the DirList event and also through the DirList property. SSHPlexControl.RemoteFile = ""; //Clear filemask SSHPlexControl.RemotePath = "MyFolder"; string opId = SSHPlexControl.ListDirectory(); // ListDirectory operates async so we must wait for it to finish while (SSHPlexControl.Operations.Keys.Contains(opId)) { SSHPlexControl.DoEvents(); } for (int i = 0; i < SSHPlexControl.DirList.Count; i++) { Console.WriteLine(SSHPlexControl.DirList[i].FileName); Console.WriteLine(SSHPlexControl.DirList[i].FileSize); Console.WriteLine(SSHPlexControl.DirList[i].FileTime); Console.WriteLine(SSHPlexControl.DirList[i].IsDir); }

The RemoteFile property may also be used as a filemask when listing files. For instance: SSHPlexControl.RemoteFile = "*.txt"; SSHPlexControl.ListDirectory();

NOTE: Because RemoteFile is used as a filemask, ensure that you clear or reset this value before calling ListDirectory

Downloading Files

The Download method downloads a specific file.

Set RemoteFile to the name of the file to download before calling this method. If RemoteFile specifies only a filename, it will be downloaded from the path specified by RemotePath. RemoteFile may also be set to an absolute path.

If LocalFile is set, the file will be saved to the specified location.

Code Example

SSHPlexControl.Localfile = "C:\localfile.txt"; SSHPlexControl.RemoteFile = "remotefile.txt"; string operationId = SSHPlexControl.Download(); // Use Path in RemoteFile SSHPlexControl.Localfile = "C:\localfile2.txt"; SSHPlexControl.RemoteFile = "folder/remotefile2.txt"; string operationId = SSHPlexControl.Download();

Resuming Downloads

The component also supports resuming failed downloads by using the StartByte property. If a download is interrupted or canceled, set StartByte to the appropriate offset before calling this method to resume the download.

string localFile = "C:\localfile.txt"; SSHPlexControl.Localfile = localFile; SSHPlexControl.RemoteFile = "remotefile.txt"; string operationId = SSHPlexControl.Download(); // Cancel Download using the CancelOperation method SSHPlexControl.CancelOperation(operationId); // Get the size of the partially downloaded temp file and set StartByte SSHPlexControl.StartByte = new FileInfo(localFile).Length; // Resume download string operationId = SSHPlexControl.Download();

Uploading Files

The Upload method is used to upload files. Set LocalFile to the name of the file to upload before calling this method.

RemoteFile should be set to either a relative or absolute path. If RemoteFile is not an absolute path, it will be uploaded relative to RemotePath.

Code Example

SSHPlexControl.Localfile = "C:\localfile.txt"; SSHPlexControl.RemoteFile = "remotefile.txt"; string operationId = SSHPlexControl.Upload(); // Use Path in RemoteFile SSHPlexControl.Localfile = "C:\localfile2.txt"; SSHPlexControl.RemoteFile = "folder/remotefile2.txt"; string operationId = SSHPlexControl.Upload();

Resuming Uploads

The component also supports resuming failed uploads by using the StartByte property. If an upload is interrupted or canceled, set StartByte to the appropriate offset before calling this method to resume the upload.

string localFile = "C:\localfile.txt"; SSHPlexControl.Localfile = localFile; SSHPlexControl.RemoteFile = "remotefile.txt"; string operationId = SSHPlexControl.Upload(); // Cancel Upload using the CancelOperation method SSHPlexControl.CancelOperation(operationId); // Get the size of the partially uploaded temp file and set StartByte SSHPlexControl.StartByte = SSHPlexControl.FileAttributes.Size; // Resume upload string operationId = SSHPlexControl.Upload();

Remote Execution

Executing commands on a remote host is done by using the cstSExec or cstSShell ChannelType.

To execute a command, simply call the Execute method with the command you wish to execute.

The output of the command is returned through the Stdout event. Errors during command execution (the stderr stream) are given by the Stderr event.

SFTPFilePermissions Property (SSHPlex Component)

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

Syntax

func (obj *SSHPlex) SFTPFilePermissions() (int32, error)
func (obj *SSHPlex) SetSFTPFilePermissions(value int32) error

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:

1 (001)Execute
2 (010)Write
4 (100)Read

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:

1 (001)Sticky Bit - retain the file in memory for performance
2 (010)Set GID - sets the group Id of the process to the file's group Id upon execution (only for executable files)
4 (100)Set UID - sets the user Id of the process to the file's user Id upon execution (only for executable files)

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

01 (000001)Named pipe
02 (000010)Character special
04 (000100)Directory
06 (000110)Block special
10 (001000)Regular
12 (001010)Symbolic link
14 (001100)Socket

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.

Data Type

int32

SFTPFilePermissionsOctal Property (SSHPlex Component)

func (obj *SSHPlex) SetFilePermissions(value string) error

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:

1 (001)Execute
2 (010)Write
4 (100)Read

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.

LocalHost Property (SSHPlex Component)

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

Syntax

func (obj *SSHPlex) LocalHost() (string, error)
func (obj *SSHPlex) SetLocalHost(value string) error

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 component initiate connections (or accept in the case of server components) 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 component 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 (SSHPlex Component)

Default Value

0

Remarks

This property must be set before a connection is attempted. It instructs the component 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 on the client side.

Data Type

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS#11 interface.

To use a security key, create a new Certificate object and pass cstPKCS11 as the SSHAcceptServerHostKeyStoreType, the full path of the PKCS#11 DLL as the SSHAcceptServerHostKeyStore, and the PIN as the SSHAcceptServerHostKeyStorePassword.

Code Example. SSH Authentication with Security Key (without CertMgr): sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll", "123456", // PIN "CN=cert_subject"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

Alternatively, collect the necessary data using the CertMgr component by calling the ListStoreCertificates method after setting the corresponding properties accordingly. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate obtained with this approach, pass the previously saved security key information as the SSHAcceptServerHostKeyStore and set SSHAcceptServerHostKeyStorePassword to the PIN.

Code Example. SSH Authentication with Security Key (with CertMgr): certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; // PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Default Value

2

Remarks

The Secure Shell (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 component 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 component 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 component supports the following authentication methods:

amNone (0)No authentication will be performed. The current SSHUser value is ignored, and the connection will be logged as anonymous.
amMultiFactor (1)This allows the component to attempt a multistep authentication process. The component will send authentication data to the server based on the list of methods allowed for the current user and the authentication property values supplied. The component will continue to send authentication data until the server acknowledges authentication success. If the server rejects an authentication step, the component fails with an error.
amPassword (2)The component will use the values of SSHUser and SSHPassword to authenticate the user.
amPublicKey (3)The component will use the values of SSHUser and the SSHCert* properties to authenticate the user. the SSHCert* properties must have a private key available for this authentication method to succeed.
amKeyboardInteractive (4)At the time of authentication, the component will fire the SSHKeyboardInteractive event containing instructions on how to complete the authentication step.

NOTE: amKeyboardInteractive is not supported in SSHTunnel.

amGSSAPIWithMic (5)This allows the component to attempt Kerberos authentication using the GSSAPI-WITH-MIC scheme. The client will try Kerberos authentication using the value of SSHUser (single sign-on), or if SSHPassword is specified as well, it will try Kerberos authentication with alternate credentials. This is currently supported only on Windows, unless using the Java edition, which also provides support for Linux and macOS.
amGSSAPIKeyex (6)This allows the component to attempt Kerberos authentication using the GSSAPIKeyex scheme. The client will try Kerberos authentication using the value of SSHUser (single sign-on), or if SSHPassword is specified as well, it will try Kerberos authentication with alternate credentials. This is currently supported only on Windows, unless using the Java edition, which also provides support for Linux and macOS.
amCustom (99)This allows the component caller to take over the authentication process completely. When amCustom is set, the component will fire the SSHCustomAuth event as necessary to complete the authentication process.

Example 1. User/Password Authentication: Control.SSHAuthMode = SftpSSHAuthModes.amPassword Control.SSHUser = "username" Control.SSHPassword = "password" Control.SSHLogon("server", 22) Example 2. Public Key Authentication: Control.SSHAuthMode = SftpSSHAuthModes.amPublicKey Control.SSHUser = "username" Control.SSHCertStoreType = SSHCertStoreTypes.cstPFXFile; Control.SSHCertStore = "cert.pfx"; Control.SSHCertStorePassword = "certpassword"; Control.SSHCertSubject = "*"; Control.SSHLogon("server", 22)

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user.

NOTE: This store type is not available in Java.

1 (cstMachine)For Windows, this specifies that the certificate store is a machine store.

NOTE: This store type is not available in Java.

2 (cstPFXFile)The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates.

NOTE: This store type is only available in Java.

5 (cstJKSBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format.

NOTE: This store type is only available in Java.

6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)The certificate store is the name of a PKCS#7 file containing certificates.
12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS#7 format.

NOTE: This store type is only available in Java and .NET.

22 (cstBCFKSBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format.

NOTE: This store type is only available in Java and .NET.

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS#11 interface.

To use a security key, create a new Certificate object and pass cstPKCS11 as the SSHCertStoreType, the full path of the PKCS#11 DLL as the SSHCertStore, and the PIN as the SSHCertStorePassword.

Code Example. SSH Authentication with Security Key (without CertMgr): sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll", "123456", // PIN "CN=cert_subject"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

Alternatively, collect the necessary data using the CertMgr component by calling the ListStoreCertificates method after setting the corresponding properties accordingly. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate obtained with this approach, pass the previously saved security key information as the SSHCertStore and set SSHCertStorePassword to the PIN.

Code Example. SSH Authentication with Security Key (with CertMgr): certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; // PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

StartByte Property (SSHPlex Component)

The offset in bytes at which to begin the upload or download.

Syntax

func (obj *SSHPlex) StartByte() (int64, error)
func (obj *SSHPlex) SetStartByte(value int64) error

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

int64

Timeout Property (SSHPlex Component)

This property includes the timeout for the class.

Syntax

func (obj *SSHPlex) Timeout() (int32, error)
func (obj *SSHPlex) SetTimeout(value int32) error

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 component will wait for the operation to complete before returning control. The component will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.

The component 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 component 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

int32

Append Method (SSHPlex Component)

Appends the data from a local file; to a remote file using SFTP.

Syntax

func (obj *SSHPlex) Append() (string, error)

Remarks

This method appends the data from LocalFile to the RemoteFile. The StartTransfer, Transfer, and EndTransfer events provide details about the individual file transfers. If the LocalFile property is "" (empty string), then the file data will be available through the Transfer event.

This method returns an Operation Id that identifies the operation in progress. A corresponding SSHPlexOperation will also be added to the Operations collection. The operation can be canceled by passing the Operation Id to the CancelOperation method.

When the operation completes, the AppendComplete event will fire, and the SSHPlexOperation associated with the completed operation will be removed from the Operations collection. Inspect the parameters of the AppendComplete event to determine the result.

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

This method is applicable only when ChannelType is set to cstSftp.

Code Example

SSHPlexControl.Localfile = "C:\localfile.txt"; SSHPlexControl.RemoteFile = "remotefile.txt"; string operationId = SSHPlexControl.Append(); // Use Path in RemoteFile SSHPlexControl.Localfile = "C:\localfile2.txt"; SSHPlexControl.RemoteFile = "folder/remotefile2.txt"; string operationId = SSHPlexControl.Append();

CancelOperation Method (SSHPlex Component)

Cancels the operation specified by OperationId .

Syntax

func (obj *SSHPlex) CancelOperation(OperationId string) error

Remarks

When this method is called, the Error event will fire and the associated operation's completion event will fire.

For example, if CancelOperation is called for an upload that is in progress, both the Error event and the UploadComplete event will fire.

The SSHPlexOperation associated with the OperationId will be removed from the Operations collection.

ChangeRemotePath Method (SSHPlex Component)

This method changes the current path on the FTP server.

Syntax

func (obj *SSHPlex) ChangeRemotePath(RemotePath string) error

Remarks

This method changes the current path on the FTP server to the specified RemotePath. When called, the component 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 instance:

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 instance:

//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 (SSHPlex Component)

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

Syntax

func (obj *SSHPlex) CheckFileExists() (bool, error)

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 (SSHPlex Component)

Sets or retrieves a configuration setting.

Syntax

func (obj *SSHPlex) Config(ConfigurationString string) (string, error)

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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 (SSHPlex Component)

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

Syntax

func (obj *SSHPlex) Connect() error

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 (e.g., confirming a host is available by first creating the connection).

CreateFile Method (SSHPlex Component)

Creates a file on the remote server using SFTP.

Syntax

func (obj *SSHPlex) CreateFile(FileName string) (string, error)

Remarks

This method creates an empty file on the server with the name specified by the FileName parameter. FileName is either an absolute path on the server or a path relative to RemotePath.

This method returns an Operation Id that identifies the operation in progress. A corresponding SSHPlexOperation will also be added to the Operations collection. The operation can be canceled by passing the Operation Id to the CancelOperation method.

When the operation completes, the CreateFileComplete event will fire, and the SSHPlexOperation associated with the completed operation will be removed from the Operations collection. Inspect the parameters of the CreateFileComplete event to determine the result.

To upload a file with content, use Upload instead.

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

This method is applicable only when ChannelType is set to cstSftp.

DeleteFile Method (SSHPlex Component)

Deletes a file on the remote server using SFTP.

Syntax

func (obj *SSHPlex) DeleteFile(FileName string) (string, error)

Remarks

This method deletes a file on the server with the name specified by the FileName parameter. FileName is either an absolute path on the server or a path relative to RemotePath.

This method returns an Operation Id that identifies the operation in progress. A corresponding SSHPlexOperation will also be added to the Operations collection. The operation can be canceled by passing the Operation Id to the CancelOperation method.

When the operation completes, the DeleteFileComplete event will fire, and the SSHPlexOperation associated with the completed operation will be removed from the Operations collection. Inspect the parameters of the DeleteFileComplete event to determine the result.

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

This method is applicable only when ChannelType is set to cstSftp.

Disconnect Method (SSHPlex Component)

Disconnects from the server without first logging off.

Syntax

func (obj *SSHPlex) Disconnect() error

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 (SSHPlex Component)

This method processes events from the internal message queue.

Syntax

func (obj *SSHPlex) DoEvents() error

Remarks

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

Download Method (SSHPlex Component)

Download a RemoteFile using SFTP or SCP.

Syntax

func (obj *SSHPlex) Download() (string, error)

Remarks

This method downloads the remote file specified by RemoteFile to the local file specified by LocalFile. The StartTransfer, Transfer, and EndTransfer events provide details about the individual file transfers. If the LocalFile property is "" (empty string) then the file data will be available through the Transfer event.

This method returns an Operation Id that identifies the operation in progress. A corresponding SSHPlexOperation will also be added to the Operations collection. The operation can be canceled by passing the Operation Id to the CancelOperation method.

When the operation completes the DownloadComplete event will fire, and the SSHPlexOperation associated with the completed operation will be removed from the Operations collection. Inspect the parameters of the DownloadComplete event to determine the result.

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

This method is applicable only when ChannelType is set to cstSftp or cstScp.

Set RemoteFile to the name of the file to download before calling this method. If RemoteFile specifies only a filename, it will be downloaded from the path specified by RemotePath. RemoteFile may also be set to an absolute path.

If LocalFile is set, the file will be saved to the specified location.

Code Example

SSHPlexControl.Localfile = "C:\localfile.txt"; SSHPlexControl.RemoteFile = "remotefile.txt"; string operationId = SSHPlexControl.Download(); // Use Path in RemoteFile SSHPlexControl.Localfile = "C:\localfile2.txt"; SSHPlexControl.RemoteFile = "folder/remotefile2.txt"; string operationId = SSHPlexControl.Download();

Resuming Downloads

The component also supports resuming failed downloads by using the StartByte property. If a download is interrupted or canceled, set StartByte to the appropriate offset before calling this method to resume the download.

string localFile = "C:\localfile.txt"; SSHPlexControl.Localfile = localFile; SSHPlexControl.RemoteFile = "remotefile.txt"; string operationId = SSHPlexControl.Download(); // Cancel Download using the CancelOperation method SSHPlexControl.CancelOperation(operationId); // Get the size of the partially downloaded temp file and set StartByte SSHPlexControl.StartByte = new FileInfo(localFile).Length; // Resume download string operationId = SSHPlexControl.Download();

Downloading Multiple Files Using a Filemask

NOTE: Using a filemask for downloads is applicable only when ChannelType is set to cstScp. 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. See RemoteFile for more information.

SSHCustomAuth Event (SSHPlex Component)

Fired when the class is doing a custom authentication.

Syntax

// SSHPlexSSHCustomAuthEventArgs carries the SSHPlex SSHCustomAuth event's parameters.
type SSHPlexSSHCustomAuthEventArgs struct {...}

func (args *SSHPlexSSHCustomAuthEventArgs) Packet() string
func (args *SSHPlexSSHCustomAuthEventArgs) SetPacket(value string)

// SSHPlexSSHCustomAuthEvent defines the signature of the SSHPlex SSHCustomAuth event's handler function.
type SSHPlexSSHCustomAuthEvent func(sender *SSHPlex, args *SSHPlexSSHCustomAuthEventArgs)

func (obj *SSHPlex) GetOnSSHCustomAuthHandler() SSHPlexSSHCustomAuthEvent
func (obj *SSHPlex) SetOnSSHCustomAuthHandler(handlerFunc SSHPlexSSHCustomAuthEvent)

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 (SSHPlex Component)

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

Syntax

// SSHPlexSSHKeyboardInteractiveEventArgs carries the SSHPlex SSHKeyboardInteractive event's parameters.
type SSHPlexSSHKeyboardInteractiveEventArgs struct {...}

func (args *SSHPlexSSHKeyboardInteractiveEventArgs) Name() string
func (args *SSHPlexSSHKeyboardInteractiveEventArgs) Instructions() string
func (args *SSHPlexSSHKeyboardInteractiveEventArgs) Prompt() string
func (args *SSHPlexSSHKeyboardInteractiveEventArgs) Response() string
func (args *SSHPlexSSHKeyboardInteractiveEventArgs) SetResponse(value string)
func (args *SSHPlexSSHKeyboardInteractiveEventArgs) EchoResponse() bool

// SSHPlexSSHKeyboardInteractiveEvent defines the signature of the SSHPlex SSHKeyboardInteractive event's handler function.
type SSHPlexSSHKeyboardInteractiveEvent func(sender *SSHPlex, args *SSHPlexSSHKeyboardInteractiveEventArgs)

func (obj *SSHPlex) GetOnSSHKeyboardInteractiveHandler() SSHPlexSSHKeyboardInteractiveEvent
func (obj *SSHPlex) SetOnSSHKeyboardInteractiveHandler(handlerFunc SSHPlexSSHKeyboardInteractiveEvent)

Remarks

SSHKeyboardInteractive is fired during the user authentication stage of the Secure Shell (SSH) logon process. During authentication, the component will request a list of available authentication methods for the SSHUser. For example, if the SSHHost responds with "keyboard-interactive", the component 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 component will fire the SSHKeyboardInteractive event once for each prompt.

SSHServerAuthentication Event (SSHPlex Component)

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

Syntax

// SSHPlexSSHServerAuthenticationEventArgs carries the SSHPlex SSHServerAuthentication event's parameters.
type SSHPlexSSHServerAuthenticationEventArgs struct {...}

func (args *SSHPlexSSHServerAuthenticationEventArgs) CertIssuer() string
func (args *SSHPlexSSHServerAuthenticationEventArgs) Status() string
func (args *SSHPlexSSHServerAuthenticationEventArgs) Accept() bool
func (args *SSHPlexSSHServerAuthenticationEventArgs) SetAccept(value bool)

// SSHPlexSSHServerAuthenticationEvent defines the signature of the SSHPlex SSHServerAuthentication event's handler function.
type SSHPlexSSHServerAuthenticationEvent func(sender *SSHPlex, args *SSHPlexSSHServerAuthenticationEventArgs)

func (obj *SSHPlex) GetOnSSHServerAuthenticationHandler() SSHPlexSSHServerAuthenticationEvent
func (obj *SSHPlex) SetOnSSHServerAuthenticationHandler(handlerFunc SSHPlexSSHServerAuthenticationEvent)

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. To configure the encoding format used when displaying this value, see SSHFingerprintEncoding.

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
To limit the accepted host key algorithms, refer to SSHPublicKeyAlgorithms.

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.

Config Settings (SSHPlex Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

SFTPClient Config Settings

AllowBackslashInName:   Whether backslashes are allowed in folder and file names.

By default the backslash character is treated as a path separator and is not allowed in file and folder names. When this configuration setting is set to True, backslashes "\" are allowed in file and folder names and are not supported as path separators.

The default value is False.

AsyncTransfer:   Controls whether simultaneous requests are made to read or write files.

When set to True, the component will make several requests to read or write data before waiting for a response from the server. The maximum number of these requests that can be made is controlled by MaxOutstandingPackets. The default is True.

AttrAccessTime:   Can be queried for the AccessTime file attribute during the DirList event.

During DirList, this configuration setting can be queried to retrieve the value of the AccessTime file attribute if it is present in the response from the server.

AttrCreationTime:   Can be queried for the CreationTime file attribute during the DirList event.

During DirList, this configuration setting can be queried to retrieve the value of the CreationTime file attribute if it is present in the response from the server.

AttrFileType:   Can be queried for the FileType file attribute during the DirList event.

During DirList, this configuration setting can be queried to retrieve the value of the FileType file attribute if it is present in the response from the server.

AttrGroupId:   Can be queried for the GroupId file attribute during the DirList event.

During DirList, this configuration setting can be queried to retrieve the value of the GroupId file attribute if it is present in the response from the server.

AttrLinkCount:   Can be queried for the LinkCount file attribute during the DirList event.

During DirList, this configuration setting can be queried to retrieve the value of the LinkCount file attribute if it is present in the response from the server.

AttrOwnerId:   Can be queried for the OwnerId file attribute during the DirList event.

During DirList, this configuration setting can be queried to retrieve the value of the OwnerId file attribute if it is present in the response from the server.

AttrPermission:   Can be queried for the Permissions file attribute during the DirList event.

During DirList, this configuration setting can be queried to retrieve the value of the Permissions file attribute if it is present in the response from the server.

CheckFileHash:   Compares a server-computed hash with a hash calculated locally.

This setting may be queried to compare a hash of the file specified by RemoteFile with the hash calculated by the server. When queried, the component will ask the server to calculate a hash of the file. It will then compute a hash locally and compare the values to confirm that the content that exists in the file specified by RemoteFile is the same as the file specified by LocalFile.

The server must support the check-file extension.

The component supports the following hash algorithms (in order of preference): sha256,sha224,sha384,sha512,sha1,md5. The server may choose to use any value from this list. No action is needed to configure the algorithm, the component will automatically use the same algorithm that the server users.

If the extension is unsupported or a mismatch in hashes is detected, the component fails with an error. If the hashes match the value, True is returned. try { String flag = sftp.Config("CheckFileHash"); // flag will be equal to "True" } catch (Exception e) { // mismatch }

DisableRealPath:   Controls whether or not the SSH_FXP_REALPATH request is sent.

This configuration setting can be used to skip sending the SSH_FXP_REALPATH request, which asks the server to canonicalize the value in RemotePath to an absolute path. The default value is False, which will cause the component to send the request normally. If set to True, the component will not send the SSH_FXP_REALPATH packet and will use the value in RemotePath directly.

ExcludeFileMask:   Specifies a file mask for excluding files in directory listings.

This configuration setting specifies one or more file masks to be excluded during a directory listing. When using multiple masks, any files that match one or more of the masks will not be listed. For example, setting ExcludeFileMask to "*.txt", RemoteFile to "", and calling ListDirectory will list all files except those ending in .txt.

ExecFallbackCommand:   Specifies the fallback command to execute if the component fails to start the SFTP subsystem.

This configuration setting specifies the fallback command to execute if the component fails to start the SFTP subsystem. By default, this config is set to the following commands:

test -x /usr/lib/sftp-server && exec /usr/lib/sftp-server\ntest -x /usr/local/lib/sftp-server && exec /usr/local/lib/sftp-server\nexec sftp-server

When initiating a connection to an SFTP server, the component will always attempt to start the SFTP subsystem for the given connection. However, in the event the SFTP subsystem cannot be started successfully for any reason, this command (or set of commands) will be executed on the server in an attempt to start the SFTP server.

If necessary, this config may be set to another command or an empty string. An empty string indicates there should be no fallback command executed, and the component will throw an exception assuming the SFTP subsystem cannot be started.

FileMaskDelimiter:   Specifies a delimiter to use for setting multiple file masks in the RemoteFile property.

If specified, the RemoteFile property will be split into separate masks based on the chosen delimiter. The default is "", which will cause the RemoteFile property to be treated as a single value. When using multiple masks, any files that match one or more of the masks will be listed. For example, setting FileMaskDelimiter to "," and setting RemoteFile to "*.txt, *.csv" will list all files ending in .txt or .csv.

FiletimeFormat:   Specifies the format to use when returning filetime strings.

If specified, the component will use this value to format the filetime string returned through the DirList event. By default, the component will format the date as "MM/dd/yyyy HH:mm:ss".

ForceMakeDirectory:   Controls whether calls to make a directory always attempt to create the directory on the server.

By default (false), when MakeDirectory is called, the component will first check if a file or directory already exists at the specified path. If an entry exists, the operation will succeed without sending a directory creation request to the server. When this configuration setting is set to True, the component will always send the directory creation request to the server regardless of whether the path already exists. This allows the server to determine the outcome of the operation.

This is useful in cases where a file may exist at the specified path. In such cases, many servers will return an error when attempting to create a directory with the same name, allowing the application to detect the conflict.

FreeSpace:   The free space on the remote server in bytes.

This property is populated after calling the GetSpaceInfo configuration setting. This holds the total free space available on the drive on the remote server in bytes.

GetSpaceInfo:   Queries the server for drive usage information.

This configuration setting queries the server for the total space and free space available on the remote drive. When querying this setting, the component will immediately request the information from the server. After calling this setting the TotalSpace and FreeSpace configuration settings will be populated.

NOTE: The server must understand either the "statvfs@openssh.com" or "space-available" extension for this operation to succeed.

GetSymlinkAttrs:   Whether to get the attributes of the symbolic link, or the resource pointed to by the link.

When FileAttributes is queried, the component will retrieve information about the RemoteFile. This configuration setting controls the behavior when RemoteFile refers to a symbolic link on the server. By default the information returned by FileAttributes is that of the actual file pointed to by the symbolic link, not the symbolic link itself.

If it is desired to retrieve the attributes of the symbolic link itself, set GetSymlinkAttrs to True before querying FileAttributes.

IgnoreFileMaskCasing:   Controls whether or not the file mask is case sensitive.

This configuration setting applies to the file mask value specified by the RemoteFile property. The default value is True. If set to False, the file mask will be case sensitive.

LocalEOL:   When TransferMode is set, this specifies the line ending for the local system.

This configuration setting is applicable only when TransferMode is set to 1 (ASCII). The default value is a CrLf character sequence.

When uploading or downloading, this value will be compared to ServerEOL. If ServerEOL and LocalEOL are different, the line endings in the file being transferred will be converted to the line endings used by the destination. Line endings will be converted to the value in LocalEOL when downloading. Line endings will be converted to the value in ServerEOL when uploading. If ServerEOL and LocalEOL are the same, no conversion takes place.

The value supplied to this setting must be quoted. For example: component.Config("LocalEOL=\"" + myEOLSequence + "\""); Where myEOLSequence is a Cr, Lf, or CrLf character sequence.

Conversion will only happen when TransferMode is set to 1 (ASCII) and ServerEOL and LocalEOL are different.

LogSFTPFileData:   Whether SFTP file data is present in Debug logs.

This configuration setting controls whether file data is logged when LogLevel is set to 3 (Debug). When False (default), the file data being transferred is not included. Set this value to True to include all traffic include file data.

NOTE: Setting this value to True will increase the amount of data that are logged.

MaskSensitiveData:   Masks passwords in logs.

The default value is True. When set to True, the component will mask passwords that otherwise would appear in its logs.

MaxFileData:   Specifies the maximum payload size of an SFTP packet.

Although the Secure Shell (SSH) specification requires servers and clients to support SSH packets of at least 32,000 bytes, some server implementations limit the packet size to smaller values. MaxFileData provides a means by which the user can specify the maximum amount of data that can be put into a Secure File Transfer Protocol (SFTP) packet so that the component can communicate effectively with these servers. If you are having difficulty when uploading to a server, try setting MaxFileData size to a value smaller than 32,000.

Most servers that use smaller values will use a maximum SSH packet size of 16KB (16384). To most efficiently communicate with such servers, MaxFileData size should be set to 14745.

NOTE: Values larger than 64,000 (65,536) may not be respected by some servers (such as OpenSSH) and will result in unexpected behavior. If specifying a value, it is recommended to set a value less than or equal to 65,536.

The default value is 32,768.

MaxOutstandingPackets:   Sets the maximum number of simultaneous read or write requests allowed.

This configuration setting sets the number of simultaneous read or write requests allowed. This configuration setting applies only when AsyncTransfer is True. The default is 32.

NegotiatedProtocolVersion:   The negotiated SFTP version.

This configuration setting returns the negotiated version of SFTP. Query this to ensure that the correct version was negotiated. This configuration setting is read only.

NormalizeRemotePath:   Whether to normalize the RemotePath.

When set to True, the component will normalize the value in RemotePath by appending a forward slash (/) if one is not already present. "." and ".." are special cases and will not be affected. The default is True.

PreserveFileTime:   Preserves the file's timestamps during transfer.

If set to True, the component will preserve the file's timestamps during transfer. This is applicable to both uploads and downloads. The default value is False.

ProtocolVersion:   The highest allowable SFTP version to use.

This configuration setting governs the highest allowable SFTP version to use when negotiating the version with the server. The default value is 3 because this is the most common version. The component supports values from 3 to 6. It is recommended to use the default value of 3 unless there is a specific reason a higher version is needed.

ReadLink:   This settings returns the target of a specified symbolic link.

This configuration setting returns the target of the specified symbolic link. To use the setting, pass the remote path and file name of the symbolic link. For example: string resolvedPath = component.Config("ReadLink=/home/test/mysymlink.txt");

RealTimeUpload:   Enables real time uploading.

When this value is set to True, the component will upload the data in the file specified by LocalFile and continue monitoring LocalFile for additional data to upload until no new data are found for RealTimeUploadAgeLimit seconds. This allows you to start uploading a file immediately after the file is created and continue uploading as data is written to the file. The default value is False.

RealTimeUploadAgeLimit:   The age limit in seconds when using RealTimeUpload.

This value is applicable only when RealTimeUpload is set to True. This specifies the number of seconds for which the component will monitor LocalFile for new data to upload. If this limit is reached and no new data are found in LocalFile, the upload will complete. The default value is 1.

ServerEOL:   When TransferMode is set, this specifies the line ending for the remote system.

This configuration setting is applicable only when TransferMode is set to 1 (ASCII). The default value is a CrLf character sequence.

When uploading or downloading, this value will be compared to LocalEOL. If ServerEOL and LocalEOL are different, the line endings in the file being transferred will be converted to the line endings used by the destination. Line endings will be converted to the value in LocalEOL when downloading. Line endings will be converted to the value in ServerEOL when uploading. If ServerEOL and LocalEOL are the same, no conversion takes place.

The value supplied to this setting must be quoted. For example: component.Config("ServerEOL=\"" + myEOLSequence + "\""); Where myEOLSequence is a Cr, Lf, or CrLf character sequence.

Conversion will happen only when TransferMode is set to 1 (ASCII) and ServerEOL and LocalEOL are different.

SimultaneousTransferLimit:   The maximum number of simultaneous file transfers.

This configuration setting specifies the maximum number of simultaneous file transfers. This is used when processing files added to the transfer queue by QueueFile. The default value is 5.

TotalSpace:   The total space on the remote server in bytes.

This property is populated after calling the GetSpaceInfo configuration setting. This holds the total space on the drive on the remote server in bytes.

TransferMode:   The transfer mode (ASCII or Binary).

The value 0 represents binary and the value 1 represents ASCII. If the value is 0 (default), the initial server mode will be used.

When this value is set to 1 (ASCII) the component will use the values specified in LocalEOL and ServerEOL to convert line endings as appropriate.

NOTE: When this value is set to 1 (ASCII) and ProtocolVersion is set to 4 or higher the component will automatically determine the value for ServerEOL if the server supports the newline protocol extension.

TransferredDataLimit:   Specifies the maximum number of bytes to download from the remote file.

This configuration setting specifies the maximum number of bytes that should be downloaded from the current RemoteFile when Download is called. The component will stop downloading data if it reaches the specified limit, or if there are no more data to download.

This configuration setting can be used in conjunction with the StartByte property to download a specific range of data from the current RemoteFile.

UseFxpStat:   Whether SSH_FXP_STAT is sent.

For certain operations the component will send SSH_FXP_STAT to get a file's attributes. Some servers do not support this packet and will return an error.

Set this to false to not send the packet. This will cause PreserveFileTime to not work and prevent PercentDone in Transfer from being calculated.

The default is true.

UseServerFileTime:   Controls if the file time returned from the server is converted to local time or not.

If this configuration setting is set to False, the component will return the filetime as the system's local time; otherwise, it will return with the time as it is reported by the server. The default is false.

SCP Config Settings

DirectoryPermissions:   The permissions of folders created on the remote host.

This configuration setting is applicable only when RecursiveMode is set to True. If new folders are created on the remote host as a result of the Upload operation, this configuration setting specifies the permissions these new folders will be assigned. This is a four-digit (4-digit) octal value. See FilePermissions for more details on expected values. The default value is "0700".

LastAccessedTime:   The last accessed time of the remote file.

This configuration setting returns the last accessed time of the remote file. It is applicable only for download when PreserveFileTime is set to True. This may be queried within the StartTransfer event.

LastModifiedTime:   The last modified time of the remote file.

This configuration setting returns the last modified time of the remote file. It is applicable only for download when PreserveFileTime is set to True. This may be queried within the StartTransfer event.

PreserveFileTime:   Preserves the file's modified time during transfer.

If this configuration setting is set to True, the component will preserve the file's modified time during transfer. This is applicable to both uploads and downloads. The default value is True.

When enabled, the component will also populate LastModifiedTime and LastAccessedTime configuration settings. These are applicable only during download and may be used to check the times of the remote file from within the StartTransfer event. To cancel a transfer, call the Interrupt method.

RecursiveMode:   If set to true the component will recursively upload or download files.

When a filemask is specified in LocalFile or RemoteFile this configuration setting specifies if subdirectories and files are transferred as well. By default, this value is False and only files in the specified directory will be transferred. If set to True, recursion will be used to transfer all child folders and files.

ServerResponseWindow:   The time to wait for a server response in milliseconds.

After an operation is complete, the server may still return an error. This configuration setting controls the amount of time the component will wait for an error to be returned. This value is specified in milliseconds. The default value is "20".

SShell Config Settings

DisconnectOnChannelClose:   Whether to automatically close the connection when a channel is closed.

If this is True, then any time a channel is closed the connection will close as well. When False, the connection will remain open any time a channel is closed.

Default is True.

EncodedTerminalModes:   The terminal mode to set when communicating with the SSH host.

This configuration setting may be set to specify a terminal mode when communicating with the SSH host. This will automatically be set if TerminalModes is set. This is provided as an alternative to TerminalModes, as follows:

component.Config("EncodedTerminalModes=" + Encoding.Default.GetString(new byte[] { 53,0,0,0,0,0 })"); In this example, the first byte is the opcode (53 for echo). The next 4 bytes represent the opcode value, which is a uint 32. The last byte is always a null character to end the string. This example sets echo to off just as in the example for TerminalModes.

FallbackKeyboardAuth:   Whether to attempt keyboard authorization after another authorization method has failed.

If this is True, then when an authentication attempt (that is not already using keyboard authentication) fails, the SSHKeyboardInteractive event will fire. The Response from that event will then be used in a password authentication attempt. If that attempt also fails, the SSHKeyboardInteractive event will fire one more time for an actual keyboard authentication attempt.

Default is False.

ShellPrompt:   The character sequence of the prompt on the SSH host to wait for.

If set, when Execute is called, the component will wait for the ShellPrompt value to be returned by the server.

StdInFile:   The file to use as Stdin data.

This configuration setting provides the contents of a file as the Stdin input to the SSH server. Set this to the full path and name of the target file.

StripANSI:   Whether to remove ANSI escape sequences.

This configuration setting specifies whether the component removes ANSI escape sequences from the data returned by the server. The default value is False, and data will be provided exactly as they are returned by the server.

TerminalHeight:   The height of the terminal display.

When a connection to the SSH server is made, this option specifies the height of the terminal's display in rows.

TerminalModes:   The terminal mode to set when communicating with the SSH host.

This configuration setting may be set to specify one or more terminal modes when communicating with the Secure Shell (SSH) host. The values are passed as a comma-separated list of opcode=value pairs, as follows:

component.Config("TerminalModes=53=0"); In this example, 53 is the opcode (for echo) and the value is 0. So this sets echo to off.

TerminalType:   The terminal type the component will use when connecting to a server.

This specifies a terminal type when communicating with a Secure Shell (SSH) host. The default value is "vt100", additional supported terminal types will depend on the SSH host.

TerminalUsePixel:   Whether the terminal's dimensions are in columns/rows or pixels.

When this option is True, the TerminalHeight and TerminalWidth configuration options are in pixels instead of columns and rows. The default is False.

TerminalWidth:   The width of the terminal display.

When a connection to the SSH server is made, this option specifies the width of the terminal's display in columns.

UpdateTerminalSize:   Used to update the terminal size.

This configuration setting will send the updated terminal size to the SSHHost when it is called. Before calling this setting, set TerminalHeight and TerminalWidth to the new values. Then simply call this setting, for instance: sshell.Config("UpdateTerminalSize");

SExec Config Settings

DisconnectOnChannelClose:   Whether to automatically close the connection when a channel is closed.

If this is True, then any time a channel is closed, the connection will close as well. When False, the connection will remain open any time a channel is closed.

Default is False.

EncodedTerminalModes:   The terminal mode to set when communicating with the SSH host.

This configuration setting may be set to specify a terminal mode when communicating with the SSH host. This will automatically be set if TerminalModes is set. This is provided as an alternative to TerminalModes, as follows:

component.Config("EncodedTerminalModes=" + Encoding.Default.GetString(new byte[] { 53,0,0,0,0,0 })"); In this example, the first byte is the opcode (53 for echo). The next 4 bytes represent the opcode value, which is a uint 32. The last byte is always a null character to end the string. This example sets echo to off just as in the example for TerminalModes.

StdInFile:   The file to use as Stdin data.

This configuration setting provides the contents of a file as the Stdin input to the SSH server. Set this to the full path and name of the target file.

TerminalHeight:   The height of the terminal display.

When a connection to the SSH server is made, this option specifies the height of the terminal's display in rows.

TerminalModes:   The terminal mode to set when communicating with the SSH host.

This configuration setting may be set to specify one or more terminal modes when communicating with the Secure Shell (SSH) host. The values are passed as a comma-separated list of opcode=value pairs, as follows:

component.Config("TerminalModes=53=0"); In this example, 53 is the opcode (for echo) and the value is 0. So this sets echo to off.

TerminalUsePixel:   Whether the terminal's dimensions are in columns/rows or pixels.

When this option is True, the TerminalHeight and TerminalWidth configuration options are in pixels instead of columns and rows. The default is False.

TerminalWidth:   The width of the terminal display.

When a connection to the SSH server is made, this option specifies the width of the terminal's display in columns.

UseTerminal:   Whether to executes commands within a pseudo-terminal.

If set to true, the component will create a pseudo-terminal (pty-req) and will execute commands within this terminal. When SSHLogoff is called, any ongoing processes will be terminated by the server. If set to false (default), commands are not executed within a terminal and any ongoing processes will continue to run even after SSHLogoff is called.

SSHClient Config Settings

ChannelDataEOL[ChannelId]:   Used to break the incoming data stream into chunks.

By default MaxChannelDataLength is 0 and ChannelDataEOL is an empty string. SSHChannelData fires whenever an SSH_MSG_CHANNEL_DATA packet is received.

If MaxChannelDataLength is greater than 0 and ChannelDataEOL is a nonempty string, the component will internally buffer data waiting to fire SSHChannelData until either MaxChannelDataLength is reached or ChannelDataEOL is found, whichever comes first. Query ChannelDataEOLFound to know which condition was met. The buffer is reset any time SSHChannelData fires.

ChannelDataEOL and MaxChannelDataLength must be set together or unexpected behavior could occur.

ChannelDataEOLFound[ChannelId]:   Determines if ChannelDataEOL was found.

If true,then ChannelDataEOL was found. If false, then MaxChannelDataLength was reached.

This configuration setting is valid only when queried inside SSHChannelData, MaxChannelDataLength > 0, and ChannelDataEOL is nonempty.

ClientSSHVersionString:   The SSH version string used by the component.

This configuration setting specifies the Secure Shell (SSH) version string used by the component. The default value is "SSH-2.0-IPWorks SSH Client 2024".

Most SSH servers expect the SSH version string to have the expected format "SSH-protocol version-software version". See above for an example.

ConnectAndLogin:   Whether the component performs a full SSH login.

The default value is true. When enabled, calling the Connect method establishes the TCP connection and performs a full SSH login.

When set to false, calling Connect will only establish the underlying TCP connection; the SSH login will not be performed. This may be useful in cases in which it is desirable to separate the connection and logon operations; for instance, confirming a host is available before authenticating with it.

When ConnectAndLogin is false, call SSHLogon with the same SSHHost and SSHPort used to connect in order to complete the SSH login over the existing connection. Note that SSHLogon always performs a full SSH login regardless of the value of this configuration setting.

DoNotRepeatAuthMethods:   Whether the component will repeat authentication methods during multifactor authentication.

The default value is true. When set to false, the component will repeat authentication methods that have already been completed during multifactor authentication.

EnablePageantAuth:   Whether to use a key stored in Pageant to perform client authentication.

This configuration setting controls whether Pageant authentication is disabled, enabled, or required. When enabled or required, the component attempts to communicate with PuTTY's ssh-agent, called "Pageant", over shared memory to perform public key authentication. Possible values and the corresponding behavior is described as follows:

ValueDescription
0 (Disabled - default) No communication with Pageant is attempted.
1 (Enabled) Pageant authentication is used if available. If Pageant is not running, or does not contain the expected key, no error is thrown.
2 (Required) Only Pageant authentication is used. If Pageant is not running, or does not contain the expected key, an error is thrown.

Example 1. Enabling Pageant: component.Config("EnablePageantAuth=1"); component.SSHUser = "sshuser"; component.SSHLogon("localhost", 22);

NOTE: This functionality is available only on Windows.

ForceDisconnect:   Whether to skip sending channel close and disconnect packets when disconnecting.

This configuration setting controls whether the component sends the SSH_MSG_CHANNEL_CLOSE and SSH_MSG_DISCONNECT packets to the server when Disconnect or SSHLogoff is called.

When set to true, the component will skip sending these packets and close the underlying connection immediately. This is useful when the connection is unresponsive, such as when the remote host has stopped responding during a transfer, since sending these packets is otherwise subject to Timeout like any other operation. Note that when this setting is enabled, the server will not be notified that the connection is closing.

The default value is false, meaning the component will attempt a graceful disconnection by sending these packets before closing the connection.

KerberosDelegation:   If true, asks for credentials with delegation enabled during authentication.

The default value is "True". If set to "False", the client will not ask for credentials delegation support during authentication.

NOTE: Even if the client asks for delegation, the server/KDC might not grant it, and authentication will still succeed.

KerberosRealm:   The fully qualified domain name of the Kerberos Realm to use for GSSAPI authentication.

This property may be set to the fully qualified (DNS) name of the kerberos realm (or Windows Active Directory domain name) to use during GSSAPI authentication. This can be used to force authentication with a given realm if the client and server machines are not part of the same domain.

KerberosSPN:   The Kerberos Service Principal Name of the SSH host.

This property can be set to specify the Service Principal Name (SPN) associated with the SSH service on the remote host. This will usually be in the form "host/fqdn.of.sshhost[@REALM]". If not specified, the component will assume the SPN is based on the value of the SSHHost property and the kerberos realm used for authentication.

KeyRenegotiationThreshold:   Sets the threshold for the SSH Key Renegotiation.

This property allows you to specify the threshold, in the number of bytes, for the Secure Shell (SSH) key renegotiation. The default value for this property is set to 1 GB.

Example. Setting the Threshold to 500 MB: SSHComponent.Config("KeyRenegotiationThreshold=524288000")

LogLevel:   Specifies the level of detail that is logged.

This configuration setting controls the level of detail that is logged through the Log event. Possible values are as follows:

0 (None) No messages are logged.
1 (Info - Default) Informational events such as Secure Shell (SSH) handshake messages are logged.
2 (Verbose) Detailed data such as individual packet information are logged.
3 (Debug) Debug data including all relevant sent and received bytes are logged.

MaxChannelDataLength[ChannelId]:   The maximum amount of data to accumulate when no ChannelDataEOL is found.

By default MaxChannelDataLength is 0 and ChannelDataEOL is an empty string. SSHChannelData fires whenever an SSH_MSG_CHANNEL_DATA packet is received.

If MaxChannelDataLength is greater than 0 and ChannelDataEOL is a nonempty string, the component will internally buffer data waiting to fire SSHChannelData until either MaxChannelDataLength is reached or ChannelDataEOL is found, whichever comes first. Query ChannelDataEOLFound to know which condition was met. The buffer is reset any time SSHChannelData fires.

ChannelDataEOL and MaxChannelDataLength must be set together or unexpected behavior could occur.

MaxPacketSize:   The maximum packet size of the channel, in bytes.

This configuration setting specifies the maximum size of an individual data packet, in bytes, that can be sent to the sender.

MaxWindowSize:   The maximum window size allowed for the channel, in bytes.

This configuration setting specifies how many bytes of channel data can be sent to the sender of this message without adjusting the window.

NOTE: This value may be changed during the connection, but the window size can only be increased, not decreased.

NegotiatedStrictKex:   Returns whether strict key exchange was negotiated to be used.

This configuration setting specifies whether strict key exchange (strict kex) was negotiated during the SSH handshake. If strict kex is being used, then this will return "True". If strict kex is not being used, then this will return "False".

component.Config("NegotiatedStrictKex")

PasswordPrompt:   The text of the password prompt used in keyboard-interactive authentication.

This configuration setting optionally specifies a pattern to be matched to the prompt received from the server during keyboard-interactive authentication. If a matching prompt is detected the component automatically responds to the prompt with the password specified by SSHPassword.

This provides an easy way to automatically reply to prompts with the password if one is presented by the server. The password will be autofilled in the Response parameter of the SSHKeyboardInteractive event in the case of a match.

The following special characters are supported for pattern matching:

? Any single character.
* Any characters or no characters (e.g., C*t matches Cat, Cot, Coast, Ct).
[,-] A range of characters (e.g., [a-z], [a], [0-9], [0-9,a-d,f,r-z]).
\ The slash is ignored and exact matching is performed on the next character.

If these characters need to be used as a literal in a pattern, then they must be escaped by surrounding them with brackets []. NOTE: "]" and "-" do not need to be escaped. See below for the escape sequences:

CharacterEscape Sequence
? [?]
* [*]
[ [[]
\ [\]

For example, to match the value [Something].txt, specify the pattern [[]Something].txt.

PreferredDHGroupBits:   The size (in bits) of the preferred modulus (p) to request from the server.

This configuration setting may be when using the diffie-hellman-group-exchange-sha1 or diffie-hellman-group-exchange-sha256 key exchange algorithms to control the preferred size, in bits, of the modulus (p) prime number to request from the server. Acceptable values are between 1024 and 8192.

RecordLength:   The length of received data records.

If set to a positive value, this configuration setting defines the length of data records to be received. The component will accumulate data until RecordLength is reached and only then will it fire the DataIn event with data of length RecordLength. This allows data to be received as records of known length. This value can be changed at any time, including within the DataIn event.

The default value is 0, meaning this setting is not used.

ServerSSHVersionString:   The remote host's SSH version string.

This configuration setting will return the remote host's SSH version string, which can help when identifying problematic servers. This configuration setting is read-only.

SignedSSHCert:   The CA signed client public key used when authenticating.

When authenticating via public key authentication, this setting may be set to the certificate authority (CA) signed client's public key. This is useful when the server has been configured to trust client keys signed by a particular CA. For instance: component.Config("SignedSSHCert=ssh-rsa-cert-v01@openssh.com AAAAB3NzaC1yc2EAAAADAQABAAAB..."); The algorithm such as ssh-rsa-cert-v01@openssh.com in the previous string is used as part of the authentication process. To use a different algorithm, simply change this value. For instance, all of the following are acceptable with the same signed public key:

  • ssh-rsa-cert-v01@openssh.com AAAAB3NzaC1yc2EAAAADAQABAAAB...
  • rsa-sha2-256-cert-v01@openssh.com AAAAB3NzaC1yc2EAAAADAQABAAAB...
  • rsa-sha2-512-cert-v01@openssh.com AAAAB3NzaC1yc2EAAAADAQABAAAB...

SSHAcceptAnyServerHostKey:   If set the component will accept any key presented by the server.

The default value is "False". Set this to "True" to accept any key presented by the server.

SSHAcceptServerCAKey:   The CA public key that signed the server's host key.

If the server's host key was signed by a CA, this configuration setting may be used to specify the CA's public key. If specified, the component will trust any server's host key that was signed by the CA. For instance: component.Config("SSHAcceptServerCAKey=ssh-rsa AAAAB3NzaC1yc2EAAAADAQAB...");

SSHAcceptServerHostKeyFingerPrint:   The fingerprint(s) of the server host keys to accept.

This configuration setting specifies one or more fingerprints that should be accepted as the servers host key. Each fingerprint should be represented using the hash algorithm and encoding format defined by the SSHFingerprintHashAlgorithm and SSHFingerprintEncoding configs, respectively.

By default, this config should be specified as the comma-separated list of hex-encoded SHA256 hashes of possible server host keys.

Example: // Assuming default values. Hex-encoded, SHA256 hash of the expected host key SSHClient.Config("SSHAcceptServerHostKeyFingerPrint=61:2d:89:9c:55:67:5e:ca:22:86:fc:f6:07:59:67:e0:c7:77:08:1f:cc:d9:93:f3:f9:63:21:15:3e:0c:a2:1b"); // Base64-encoded, SHA256 hash of the expected host key SSHClient.Config("SSHFingerprintEncoding=1"); SSHClient.Config("SSHAcceptServerHostKeyFingerPrint=n4bQgYhMfWWaL+qgxVrQFaO/TxsrC4Is0V1sFbDwCgg=");

If the server's fingerprint matches one of the values supplied, the component will accept the host key.

SSHFingerprintEncoding:   Specifies the encoding used when displaying the SSH host key fingerprint.

This setting determines how the SSH host key fingerprint is displayed after it has been computed using the algorithm specified by SSHFingerprintHashAlgorithm. Possible values are:

  • 0 (Hex Encoded)
  • 1 (Base64 Encoded - Default)

For example, when set to 0, the Fingerprint parameter in SSHServerAuthentication will be formatted like: 0a:1b:2c:3d. When set to 1, the Fingerprint parameter in SSHServerAuthentication will be formatted like: n4bQgYhMfWWaL+qgxVrQFaO/TxsrC4Is0V1sFbDwCgg=.

Note that this config is also applicable when querying the SSHFingerprintMD5, SSHFingerprintSHA1, or SSHFingerprintSHA256 configuration settings.

Additionally, note that this config is also applicable if specifying the host key fingerprint via SSHAcceptServerHostKeyFingerPrint. The value specified via SSHAcceptServerHostKeyFingerPrint should be specified according to the format or encoding specified by this configuration setting.

SSHFingerprintHashAlgorithm:   The algorithm used to calculate the fingerprint.

This configuration setting controls which hash algorithm is used to calculate the hostkey's fingerprint, displayed when SSHServerAuthentication fires. Valid values are as follows:

  • MD5
  • SHA1
  • SHA256 (default)

SSHFingerprintMD5:   The server hostkey's MD5 fingerprint.

This configuration setting may be queried in SSHServerAuthentication to get the server hostkey's MD5 fingerprint.

SSHFingerprintSHA1:   The server hostkey's SHA1 fingerprint.

This configuration setting may be queried in SSHServerAuthentication to get the server hostkey's SHA-1 fingerprint.

SSHFingerprintSHA256:   The server hostkey's SHA256 fingerprint.

This configuration setting may be queried in SSHServerAuthentication to get the server hostkey's SHA-256 fingerprint.

SSHKeepAliveCountMax:   The maximum number of keep alive packets to send without a response.

This configuration setting specifies the maximum number of keep-alive packets to send when no response is received. Normally a response to a keep-alive packet is received right away. If no response is received, the component will continue to send keep-alive packets until SSHKeepAliveCountMax is reached. If this is reached, the component will assume the connection is broken and disconnect. The default value is 5.

SSHKeepAliveInterval:   The interval between keep alive packets.

This configuration setting specifies the number of seconds between keep alive packets. If set to a positive value, the component will send a SSH keep-alive packet after KeepAliveInterval seconds of inactivity. This configuration setting takes effect only when there is no activity; if any data are sent or received over the connection, it will reset the timer.

The default value is 0, meaning no keep alives will be sent.

NOTE: The SSHReverseTunnel component uses a default value of 30.

SSHKeyExchangeAlgorithms:   Specifies the supported key exchange algorithms.

This configuration setting may be used to specify the list of supported key exchange algorithms used during Secure Shell (SSH) negotiation. The value should contain a comma-separated list of algorithms. Supported algorithms are as follows:

  • curve25519-sha256
  • curve25519-sha256@libssh.org
  • diffie-hellman-group1-sha1
  • diffie-hellman-group14-sha1
  • diffie-hellman-group14-sha256
  • diffie-hellman-group16-sha512
  • diffie-hellman-group18-sha512
  • diffie-hellman-group-exchange-sha256
  • diffie-hellman-group-exchange-sha1
  • ecdh-sha2-nistp256
  • ecdh-sha2-nistp384
  • ecdh-sha2-nistp521
  • gss-group14-sha256
  • gss-group16-sha512
  • gss-nistp256-sha256
  • gss-curve25519-sha256
  • gss-group14-sha1
  • gss-gex-sha1
  • mlkem768x25519-sha256
The default value is curve25519-sha256,curve25519-sha256@libssh.org,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,mlkem768x25519-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1,gss-group14-sha256,gss-group16-sha512,gss-nistp256-sha256,gss-curve25519-sha256,gss-group14-sha1,gss-gex-sha1.
SSHKeyRenegotiate:   Causes the component to renegotiate the SSH keys.

Once this configuration setting is queried, the component will renegotiate the SSH keys with the remote host.

Example 3. Renegotiating SSH Keys: SSHClient.Config("SSHKeyRenegotiate")

SSHMacAlgorithms:   Specifies the supported Mac algorithms.

This configuration setting may be used to specify an alternate list of supported Mac algorithms used during SSH negotiation. This also specifies the order in which the Mac algorithms are preferred. The value should contain a comma-separated list of algorithms. Supported algorithms are as follows:

  • hmac-sha1
  • hmac-md5
  • hmac-sha1-96
  • hmac-md5-96
  • hmac-sha2-256
  • hmac-sha2-256-96
  • hmac-sha2-512
  • hmac-sha2-512-96
  • hmac-ripemd160
  • hmac-ripemd160-96
  • hmac-sha2-256-etm@openssh.com
  • hmac-sha2-512-etm@openssh.com
  • hmac-sha2-256-96-etm@openssh.com
  • hmac-sha2-512-96-etm@openssh.com
  • umac-64@openssh.com
  • umac-64-etm@openssh.com
  • umac-128@openssh.com
  • umac-128-etm@openssh.com
The default value is hmac-sha2-256,hmac-sha2-512,hmac-sha1,hmac-md5,hmac-ripemd160,hmac-sha1-96,hmac-md5-96,hmac-sha2-256-96,hmac-sha2-512-96,hmac-ripemd160-96,hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com,umac-64@openssh.com,umac-64-etm@openssh.com,umac-128@openssh.com,umac-128-etm@openssh.com.
SSHPubKeyAuthSigAlgorithms:   Specifies the enabled signature algorithms that may be used when attempting public key authentication.

This setting specifies a list of signature algorithms that may be used when authenticating to the server using public key authentication. This applies only when public key authentication is performed by the client.

The setting should be a comma-separated list of algorithms. At runtime, the component will evaluate the specified algorithms, and if the algorithm is applicable to the certificate specified in SSHCert, it will be used. If the algorithm is not applicable, the component will evaluate the next algorithm. Possible values are as follows:

  • ssh-rsa
  • rsa-sha2-256
  • rsa-sha2-512
  • ssh-dss
  • ecdsa-sha2-nistp256
  • ecdsa-sha2-nistp384
  • ecdsa-sha2-nistp521
  • ssh-ed25519
  • x509v3-sign-rsa
  • x509v3-sign-dss

The default value in Windows is ssh-rsa,rsa-sha2-256,rsa-sha2-512,ssh-dss,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-ed25519.

rsa-sha2-256 and rsa-sha2-512 notes

The component will query the server for supported algorithms when connecting. If the server indicates support for rsa-sha2-256 or rsa-sha2-512 and the algorithm is present in the list defined by this setting (as in the default value), that algorithm will be used instead of ssh-rsa even when ssh-rsa appears first in the list.

For the rsa-sha2-256 and rsa-sha2-512 algorithms to be automatically preferred, the server must support the ext-info-c mechanism. In practice, older servers do not support this, and in that case, ssh-rsa will be used because it appears first in the list. Newer servers do support this mechanism, and in that case, rsa-sha2-256 or rsa-sha2-512 will be used even though it appears after ssh-rsa.

This behavior has been carefully designed to provide maximum compatibility while automatically using more secure algorithms when connecting to servers that support them.

SSHPublicKeyAlgorithms:   Specifies the supported public key algorithms for the server's public key.

This configuration setting specifies the allowed public key algorithms for the server's public key. This list controls only the public key algorithm used when authenticating the server's public key. This list has no bearing on the public key algorithms that can be used by the client when performing public key authentication to the server. The default value is ssh-ed25519,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,rsa-sha2-256,rsa-sha2-512,ssh-rsa,ssh-dss,x509v3-sign-rsa,x509v3-sign-dss.

SSHVersionPattern:   The pattern used to match the remote host's version string.

This configuration setting specifies the pattern used to accept or deny the remote host's SSH version string. It takes a comma-delimited list of patterns to match. The default value is "*SSH-1.99-*,*SSH-2.0-*" and will accept connections from SSH 1.99 and 2.0 hosts. As an example, the following value would accept connections for SSH 1.99, 2.0, and 2.99 hosts.

*SSH-1.99-*,*SSH-2.0-*,*SSH-2.99-*
TryAllAvailableAuthMethods:   If set to true, the component will try all available authentication methods.

The default value is false. When set to true, the component will try to authenticate using all methods that it has credentials for and the server supports.

UseStrictKeyExchange:   Specifies how strict key exchange is supported.

This configuration setting controls whether strict key exchange (strict kex) is enabled to mitigate the Terrapin attack. When enabled, the component will indicate support for strict key exchange by automatically including the pseudo-algorithm kex-strict-c-v00@openssh.com for client components and kex-strict-s-v00@openssh.com for server components in the list of supported key exchange algorithms.

Because both client and server must implement strict key exchange to effectively mitigate the Terrapin attack, the component provides options to further control the behavior in different scenarios. Possible values for this setting are as follows:

0Disabled. Strict key exchange is not supported in the component.
1 (default)Enabled, but not enforced. This setting enables strict key exchange, but if the remote host does not support strict key exchange the connection is still allowed to continue.
2Enabled, but will reject affected algorithms if the remote host does not support strict key exchange. If the remote host supports strict key exchange, all algorithms may be used. If the remote host does not support strict key exchange, the connection will continue only if the selected encryption and message authentication code (MAC) algorithms are not affected by the Terrapin attack.
3Required. If the remote host does not support strict key exchange, the connection will fail.

WaitForChannelClose:   Whether to wait for channels to be closed before disconnected.

This configuration setting controls whether the component will wait for a server response to the SSH_MSG_CHANNEL_CLOSE when disconnecting. When the component disconnects, it will first attempt to close all open channels by sending a SSH_MSG_CHANNEL_CLOSE for each channel. This configuration setting controls whether the component will wait for a server response after sending the messages.

When True (default), the component will wait for a response to the channel close message until the responses have been received, the server closes the connection, or Timeout seconds is reached.

When False, the component will still send the channel close messages, but it will not wait for a response and will proceed to close the connection.

WaitForServerDisconnect:   Whether to wait for the server to close the connection.

This configuration setting controls whether to wait for the server to close the connection when SSHLogoff is called.

When set to True, the component will initiate the disconnection sequence by sending SSH_MSG_DISCONNECT, but it will not close the connection and instead will wait for the server to close the connection. Setting this to True may be beneficial in circumstances in which many connections are being established, to avoid port exhaustion when sockets are in a TIME_WAIT state. Allowing the server to close the connection avoids the TIME_WAIT state of socket on the client machine.

When set to False (default), the client will close the connection. It is recommended to use this value unless there is a specific need to change it.

TCPClient Config Settings

ConnectionTimeout:   Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the component will use Timeout for establishing a connection and transmitting/receiving data.

EnableHappyEyeballs:   Whether to use the Happy Eyeballs algorithm when connecting.

When enabled, the component uses the Happy Eyeballs (RFC 8305) algorithm when connecting. Instead of connecting to a single address, all of the addresses returned when resolving the RemoteHost are collected and sorted so that IPv4 and IPv6 addresses alternate. Connection attempts are then started, in turn, to each address; the delay between starting successive attempts is controlled by the HappyEyeballsDelay setting. The first address to connect successfully is used and any other connection attempts still in progress are aborted.

This setting is a convenient alternative to setting UseIPv6 to 3.

Note that when this setting is enabled, LocalPort must be 0 and LocalHost must be empty or "localhost"; the component fails with an error if either is set to another value.

The default value is false.

FirewallAutoDetect:   Tells the component whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by components that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

NOTE: This setting is provided for use by components that do not directly expose Firewall properties.

FirewallHTTPVersion:   The HTTP version to be used when connecting through a tunneling proxy.

When FirewallType is set to a tunneling proxy, this setting dictates which HTTP version is used when connecting.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the component fails with an error.

NOTE: This setting is provided for use by components that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

NOTE: This configuration setting is provided for use by components that do not directly expose Firewall properties.

FirewallTunnelAuthScheme:   This configuration setting specifies the authentication mechanism to use when authenticating to a tunneling proxy.

Possible values are as follows:

1AuthDigest
3AuthNone
4AuthNTLM
5AuthNegotiate
FirewallType:   Determines the type of firewall to connect through.

Possible values are as follows:

0No firewall (default setting).
1Connect through a tunneling proxy. FirewallPort is set to 80.
2Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

NOTE: This setting is provided for use by components that do not directly expose Firewall properties.

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the component fails with an error.

NOTE: This setting is provided for use by components that do not directly expose Firewall properties.

HappyEyeballsDelay:   The delay, in milliseconds, between connection attempts when EnableHappyEyeballs is used.

When EnableHappyEyeballs is enabled (or UseIPv6 is set to 3), the component may attempt to connect to several candidate addresses concurrently. This setting controls the delay, in milliseconds, before a connection attempt is started to the next candidate address, giving the previous attempt a chance to succeed first.

The default value is 250.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

NOTE: This value is not applicable in macOS.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger:   When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the component returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime:   Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost:   The name of the local host through which connections are initiated or accepted.

The LocalHost setting 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 value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

If the component is connected, the LocalHost setting 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).

LocalPort:   The port in the local host where the component binds.

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

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

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

This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength:   The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate:   The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList:   A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.example.com

TCPKeepAlive:   Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

NOTE: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this configuration setting is set to False.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the component will use IPv4 exclusively. When set to 1, the component will use IPv6 exclusively. To instruct the component to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are as follows:

0 IPv4 only
1 IPv6 only
2 IPv6 with IPv4 fallback
3 Happy Eyeballs (the component will attempt to connect to IPv4 and IPv6 addresses concurrently and use whichever connects first)

Setting this configuration setting to 3 is equivalent to enabling the EnableHappyEyeballs setting. See EnableHappyEyeballs and HappyEyeballsDelay for more details.

UseNTLMv2:   Whether to use NTLM V2.

When authenticating with NTLM, this setting specifies whether NTLM V2 is used. By default this value is True and NTLM V2 will be used. Set this to False to use NTLM V1.

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method that does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

NOTE: This option is not valid for User Datagram Protocol (UDP) ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the InBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitiveData:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to false, the component will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the component to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
