/n software Adapters for BizTalk
Version 22.0 [Build 8376]

SFTP Adapter

Properties   Config Settings  

The SFTP Component adds SSH-secured file transfer capabilities to your BizTalk Server.

Remarks

The SFTP Adapter adds a complete SFTP client to your BizTalk Server that enables it with SSH-secured file download and upload functionality.

SFTP Receive Adapter

The SFTP Receive Adapter requires that a single property be set: SSHHost. You may also set an SSHPort if the server is not running on the default SSH port. In order to authenticate with the SSH server, you will need to specify an SSHUser, and either SSHPassword or SSHCert depending upon the SSHAuthMode to be used.

The adapter will connect to the SFTP server every PollingInterval and list the directory specified by RemotePath. All files that match the FileMask will be downloaded and submitted to the BizTalk Message Engine as individual messages. In order to guarantee that files are not downloaded multiple times, you may set the DeleteMode.

SFTP Send Adapter

The SFTP Send Adapter requires both an SSHHost and a RemoteFile. You may also set an SSHPort if the server is not running on the default SSH port. In order to authenticate with the SSH server, you will need to specify an SSHUser, and either SSHPassword or SSHCert depending upon the SSHAuthMode to be used.

The adapter will connect to the SFTP server whenever it has a message to send. The adapter will attempt to upload to the specified RemotePath. If Overwrite is set to True, the adapter will delete or overwrite remote files as necessary to complete the operation.

In order to prevent parallel processing by another application before your upload is complete, you may need to set a temporary upload directory via RemoteTempPath. If the temporary directory is set, the file will first be uploaded to the specified temporary directory, and will be moved to the final destination path once the upload has completed.

Please refer to the section on adapter configuration for a description of how to configure receive locations and send ports for this adapter.

Setting the SFTP Adapter Configuration Properties for a Dynamic Send Port

A dynamic send port does not provide any transport configuration options in BizTalk Explorer because it is expected that these properties will be provided with the context properties associated with the message. These properties can be set in a custom pipeline or in an orchestration. To set message configuration properties in an orchestration you can do the following:

  • Add a Construct Message shape to your orchestration.
  • Configure the Construct Message shape to construct a new message. (for example Message_2)
  • Add a Message Assignment shape to the Construct Message shape.
  • Add code to the Message Assignment shape to initialize the message that you constructed and to set the appropriate configuration properties for the message.

Configuring the SFTP Send Port with the BizTalk Server Administration Console

To configure the send port by using the BizTalk Server Administration console, use the following procedure:

To configure variables for a SFTP send port:

[,-] 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.

This property is not available in the Sender.

Firewall Property (SFTP Adapter)

A set of properties related to firewall access.

Data Type

Firewall

Remarks

This is a Firewall type property which contains fields describing the firewall through which the adapter will attempt to connect.

MaxBatchSize Property (SFTP Adapter)

The maximum size, in MB, of the current batch (0 indicates no limit).

Data Type

Integer

Default Value

0

Remarks

This property limits the maximum amount of data the adapter can store before finalizing and processing the current batch to the number of bytes indicated.

Note: the default value, "0" indicates that there is no limit on the size of the batch. This value is not recommended for production environments as it may result in extremely large batches being held in memory before the adapter moves the data to the next stage of processing.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxFileCount Property (SFTP Adapter)

The maximum number of files in the current batch (0 indicates no limit).

Data Type

Integer

Default Value

10

Remarks

This property places a limit on the number of files that can be transmitted in a single batch.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxFileSize Property (SFTP Adapter)

The maximum size, in MB, of a file in the current batch (0 indicates no limit).

Data Type

Integer

Default Value

0

Remarks

This property limits the maximum size of any file in the current transmission batch to the number of bytes indicated.

Note: the default value, "0" indicates that there is no limit on the size of the batch. This value is not recommended for production environments as it may result in extremely large batches being held in memory before the adapter moves the data to the next stage of processing.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxPersistentConnections Property (SFTP Adapter)

The maximum number of simultaneous persistent connections when sending.

Data Type

Integer

Default Value

1

Remarks

This setting specifies the maximum number of simultaneous persistent connections when sending.

The default value is 1, which limits the adapter to using one persistent connection for the adapter at any one time. This means when ConnectionLifetime is set to Persisted the send adapter will first check to see if an existing connection is present before transmitting data. In the case where a connection exists but another instance of the send port is using the connection the adapter will wait for the connection to become free. A value of 1 effectively serializes all communication for the send port through one persistent connection.

By setting a value greater than 1 a pool of persistent connections can be created. This allows multiple simultaneous persistent connections to be used. When the send adapter is active it will check to see if there are any existing connections. In the case where a connection exists but is being used by another instance of the send port it will attempt to create a new persistent connection. If creating a new persistent connection would exceed the limit specified in this setting the adapter will instead wait for a connection to become free. Setting this to a value greater than 1 allows multiple simultaneous connections to be made while still taking advantage of persistent connections to reduce the overhead of re-connecting.

Note: This only applies to the send adapter.

The default value is 1.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

MaxThreads Property (SFTP Adapter)

The maximum number of threads that the component may consume.

Data Type

Integer

Default Value

20

Remarks

This property limits the number of concurrent threads that the adapter may consume while completing its work.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

MaxTransmissionBatchSize Property (SFTP Adapter)

The maximum number of messages that can be sent in a single batch.

Data Type

Integer

Default Value

1

Remarks

This property controls the maximum size of an outbound message batch.

Note: be careful when modifying this property as it directly effects the efficiency of the transmit adapter. Setting MaxTransmissionBatchSize to a low value in an environment that requires transmission of large quantities of data will result in the adapter accumulating several small batches. If TransmitBatchMode is set to Parallel, this will result in the adapter transmitting many small batches at once and can put a heavy load on the processor.

Conversely, if TransmitBatchMode is set to Serial, setting MaxTransmissionBatchSize to a large value may result in long transmission delays as the adapter will wait on existing work to complete before accepting new messages from the BizTalk Message Engine. This is especially true when the adapter is transmitting large data.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

Other Property (SFTP Adapter)

Defines a set of configuration settings to be used by the component.

Data Type

String

Default Value

""

Remarks

The adapter accepts one or more 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 adapter, access to these internal properties is provided through the Other property.

The Other property may be set to one or more configuration settings (name/value pairs). Set one setting per line. For example: configname1=value1 configname2=value2

Overwrite Property (SFTP Adapter)

Whether or not the component should overwrite files during transfer.

Data Type

Boolean

Default Value

false

Remarks

This property is a value indicating whether or not the adapter should overwrite files on the server if they already exist. If Overwrite is false, an error will be thrown whenever RemoteFile exists before an upload operation.

This property is not available in the Receiver.

PersistentConnection Property (SFTP Adapter)

Instructs the component whether to keep the connection to the server open.

Data Type

Boolean

Default Value

false

Remarks

If set to true, the adapter will first attempt to use an existing connection. If no such connection exists, it will create a new connection. When the adapter completes, it will persist the connection so that the adapter will reuse it during the next polling interval. Setting this property to true can improve performance if you are polling very frequently.

PollingInterval Property (SFTP Adapter)

The amount of time, in seconds, between download attempts.

Data Type

Integer

Default Value

60

Remarks

The adapter will wait for the number of seconds indicated before attempting another download.

This property is not available in the Sender.

ReceivedFileDate Property (SFTP Adapter)

This property is not available in the Sender.

ReceivedFileSSHUser Property (SFTP Adapter)

The SSH user name used by the SFTP component when downloading the remote file.

Data Type

String

Default Value

""

Remarks

This value contains the SSHUser used by the SFTP adapter to authenticate before downloading the remote file. It can be read from the context of a message being received by an SFTP adapter receive location.

This property is not available in the Sender.

RemoteFile Property (SFTP Adapter)

The name of the destination file on the SSH server for uploading.

Data Type

String

Default Value

"%SourceFileName%"

Remarks

The RemoteFile is either an absolute file path, or a relative path based on RemotePath.

This property is not available in the Receiver.

RemotePath Property (SFTP Adapter)

The current path on the SSH server.

Data Type

String

Default Value

""

Remarks

The RemotePath can be used to set the working directory by setting it to either an absolute directory path or a path relative to the initial remote directory when the adapter connects to the SSH server.

RemoteTempPath Property (SFTP Adapter)

A temporary directory on the server to store files before moving them to RemotePath .

Data Type

String

Default Value

""

Remarks

If a value is specified, the adapter will directly upload the file to RemoteTempPath. Once the file transfer is complete, the adapter will move the file to the RemotePath.

This property is not available in the Receiver.

RequeueEndpoints Property (SFTP Adapter)

Whether to requeue receive endpoints if the polling interval has not been reached.

Data Type

Boolean

Default Value

false

Remarks

This setting controls whether receive endpoints are requeued for later processing if the polling interval has not yet been reached. When this setting is set to No (default) each thread will block until the polling interval for the corresponding receive location is reached. If there exist more active receive locations than MaxThreads it is possible for some threads to block the execution of others since they may be waiting for a polling interval.

When this setting is set to Yes if the polling interval has not been reached the thread will not block until the polling interval is reached, and instead the endpoint will be requeued to be processed later. This lets subsequent endpoints in the queue to be processed.

If MaxThreads is set to a low value and there are a larger number of receive locations setting this to Yes will help assure that polling intervals are respected and receive locations poll in a timely manner.

The default value is No.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

RuntimeLicense Property (SFTP Adapter)

Specifies the component runtime license key.

Data Type

String

Default Value

""

Remarks

You can use the RuntimeLicense property to set the runtime key for the adapter license.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

SSHAcceptServerHostKey Property (SFTP Adapter)

Instructs the component to accept the server host key that matches the supplied key.

Data Type

Certificate

Remarks

If the host key that will be used by the server is known in advance, this property may be set to accept the expected key. If you are using the fingerprint, you may supply it to the SSHAcceptServerHostKeyFingerPrint setting by HEX encoding the values in the form "0a:1b:2c:3d". If this property is not set the server will not be authenticated, and the connection will be refused by the client.

Note: You may also set the Accept Any field to Yes without opening the certificate selection dialog to force the adapter to unilaterally authenticate any server during the security handshake. It is strongly recommended that you use this only for testing purposes. Set the LogMode to Info to cause the adapter to report the server's credentials to Location.

SSHAuthMode Property (SFTP Adapter)

The type of authentication used by the component.

Data Type

Enumeration

Possible Values

None (0)
Multi Factor (1)
Password (2)
Public Key (3)
Keyboard Interactive (4)
GSSAPIWith Mic (5)

Default Value

2

Remarks

SSHAuthMode controls how the adapter attempts to authenticate when connecting to the SSHHost. The following authentication methods are available:

NoneThe adapter will attempt anonymous authentication.
Multi-FactorThe adapter will attempt as many authentication steps as the server requires using whatever credentials it has available.
PasswordThe adapter will send the SSHPassword to the server.
Public KeyThe adapter will send the SSHCert to the server;
Keyboard-InteractiveThe adapter will perform SSH keyboard-interactive authentication, responding automatically to the server's authentication prompts. It will supply the value of SSHPassword as the response to the "password" prompt. Note: this method is not truly keyboard-interactive, and the adapter may not recognize all prompts supplied by the server. It should be used only when the SSHHost cannot be configured to authenticate the SSHUser via more easily automated methods such as Password or Public Key.
GSSAPIWithMicThis allows the adapter 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.

SSHCert Property (SFTP Adapter)

The certificate to use for client authentication during the SSH handshake.

Data Type

Certificate

Remarks

This property is used to assign a specific certificate for SSH client authentication.

This field is used to set a Private Key Certificate.

Private key certificates may be loaded from the registry, from files in PKCS#12 format, or from a PEM file format. If you click on the ellipses, a certificate selection dialog will open. To select a private key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of certificates which have private keys will be shown below.

To select a private key certificate from a file in PKCS#12 format, select the PFX Store tab. The browse button can be used to examine the file system for PKCS#12 (.pfx or .p12) certificates. If you wish to examine the certificate, provide the password in the field provided and click on the Open button to examine the file store for certificates present. To load a certificate from PEM files, select the PEM tab. Like the PFX file selection, you can specify the password and click the Open button to examine the certificates in the PEM store, or you may paste any PEM data stored in memory.

Regardless of how you selected the certificate, once you hit the OK button, the adapter will attempt to verify that certificate selection. If successful, the subject of the certificate will be displayed in the property field. If the adapter was not able to verify the selection, a dialog box will appear instead detailing the verification error.

SSHCompressionAlgorithms Property (SFTP Adapter)

A comma-separated list of compression algorithms allowed for this connection.

Data Type

String

Default Value

"none"

Remarks

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

SSHCompressionAlgorithms must be set to a comma-separated list containing at least one of the following values:

zlibZlib compression is allowed for this connection.
noneNo compression is allowed for this connection.

SSHHost Property (SFTP Adapter)

The address of the SSH host.

Data Type

String

Default Value

""

Remarks

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

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

SSHPassword Property (SFTP Adapter)

The password for SSH password-based authentication.

Data Type

Password

Default Value

""

Remarks

SSHPassword specifies the password which is used to authenticate the client to the SSH server.

SSHPort Property (SFTP Adapter)

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

Data Type

Integer

Default Value

22

Remarks

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

SSHUser Property (SFTP Adapter)

The username for SSH authentication.

Data Type

String

Default Value

""

Remarks

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

SSOAffiliate Property (SFTP Adapter)

Specifies the name of the SSO Affiliate Application.

Data Type

String

Default Value

""

Remarks

This property allows the adapter to load credentials from an Enterprise Single Sign-On secret server.

TempPath Property (SFTP Adapter)

A temporary local directory where data can be stored before the component processes it.

Data Type

String

Default Value

""

Remarks

This property indicates a temporary directory where the adapter can store any data before the adapter processes it. If TempPath is empty, the adapter will receive all data to memory. If set, the adapter will generate and write all inbound data to a temporary file in the specified directory.

Once the file is submitted, the adapter will handle closing the file stream and deleting the temporary file. However, if the adapter is shut down during a transfer some temporary files may be left in the directory. To ensure optimal performance, server administrators should check the directory regularly and remove old or extraneous files.

This property accepts the "%TEMP%" macro, which will be replaced with the default system temporary directory at runtime. Note: by default, this property is empty and the adapter will use memory streams to store all inbound data before submitting it. It is recommended that you use a temporary directory when downloading large batches or batches containing large files to alleviate potential increased memory requirements.

This property is not available in the Sender.

Timeout Property (SFTP Adapter)

A timeout for the component.

Data Type

Integer

Default Value

60

Remarks

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

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

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

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when data is successfully sent or received.

Optionally, the behavior of the adapter may be changed to absolute timeouts, i.e. the adapter will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by the AbsoluteTimeout configuration setting.

The default value for the Timeout property is 60 (seconds).

TransmitBatchMode Property (SFTP Adapter)

How the transmitter processes batches.

Data Type

Enumeration

Possible Values

Parallel (0)
Serial (1)

Default Value

0

Remarks

This property controls how the transmitter processes message batches:

ParallelThe adapter will process however many batches the BizTalk Message Engine sends it.

The number of maximum concurrent batches may be controlled by the MaxThreads property.

SerialThe adapter will queue batches from the BizTalk Message Engine and process them one at a time.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

TransportLog Property (SFTP Adapter)

Tells the component where and how to report information about its operations.

Data Type

Log

Remarks

This is a Log type property which contains fields describing how and where the adapter will record information about its execution.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

URI Property (SFTP Adapter)

The Uniform Resource Identifier (URI) of the send port or receive location.

Data Type

String

Default Value

""

Remarks

This property specifies a URI for the send port or receive location. Setting this property is optional.

By default the adapter will automatically generate a URI. You may choose to specify your own value here to be used in place of the generated URI.

If this value is specified it must begin with the correct prefix, as seen in the default value.

Certificate Type

The digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

Store
String

The name of the certificate store for the client certificate.

The StoreType field specifies the type of the certificate store specified by Store. If the store is password protected, specify the password in StorePassword.

Store is used in conjunction with the Subject field in order to specify client certificates. If Store has a value, and Subject is set, a search for a certificate is initiated. Please refer to the Subject field for details.

Designations of certificate stores are platform-dependent.

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

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.
SPCSoftware publisher certificates.

In Java, the certificate store normally is a file containing certificates and optional private keys.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

If the provider is OpenSSL, the certificate store is a file containing a certificate and a private key. This property must be set to the name of the file.

StorePassword
String

If the certificate store is of a type that requires a password, this property is used to specify that password in order to open the certificate store.

StoreType
CertStoreTypes

The type of certificate store for this certificate.

The adapter supports both public and private keys in a variety of formats. When the cstAuto value is used the adapter will automatically determine the type. This field can take one of the following values:

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 (PKCS12) file containing certificates.

19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
20 (cstSecurityKey)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CERTMGR adapter. The ListStoreCertificates method may be called after setting CertStoreType to cstSecurityKey, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstSecurityKey; 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.cstSecurityKey, 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.

Subject
String

The subject of the certificate used for client authentication.

When this property is set, a search is performed in the current certificate store certificate with matching subject.

If an exact match is not found, the store is searched for subjects containing the value of the property.

When setting the property to a partial subject, CN= should be omitted. For example, the following code would find the certificate with subject CN=Test Certificate, OU=People, C=US

Example (Searching with partial subject)

Control.CertSubject = "Test"

If a match is not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

If a matching certificate is found, Subject is set to the full subject of the matching certificate.

Thumbprint
String

The thumbprint of the certificate.

This field is used to specify the thumbprint of the certificate. When there are multiple certificates in the store that have the same subject, the thumbprint will be used to distinguish between them.

public Firewall();

Log Type

A log where the component will record information about its operations.

Remarks

This describes how and where the adapter will record information describing its execution.

Fields

Location
String

This field describes the location where the logging information is to be written.

If the EventLog LogType has been chosen, this field must contain the name of the Event Log to which the information should be written. The default value for this field is "Application". If a value other than "Application" is set the computer must be restarted for the change to take effect. Note that the same event log must be used for all send ports and receive locations that use the same adapter.

If the File LogType has been chosen, this field must contain the location of the file to write logging information to on the file system.

The adapter also supports logging to files based on the current date and time. This allows for log files to be organized by days, months, or other intervals as specified. When specifying a log filename include a valid .NET date and time format string within the < and > characters. For instance C:\logs\sftp_<yyyyMMdd>.log or C:\logs\as2_<yyyyMMdd>T<hhmm>.log.

LogMode
LogModes

This field controls what information the adapter logs. The possible values have the following affect on the adapter's behavior:

VerboseThe adapter will report all information regarding the transport.
Info The adapter will report all major operations, as well as all warnings and errors.
WarningThe adapter will report any conditions that could result in unpredictable behavior as well as errors.
ErrorThe adapter will report all errors that prevent normal operations from completing.
FatalThe adapter will report only serious errors that cause the adapter to completely stop functioning.

LogType
LogTypes

This property controls where the adapter will log the information. The possible values have the following affect on the adapter's behavior:

NoneThe adapter will not report any logging information.
EventLogThe adapter will report all logging information to the event log. The specific event log must be defined in the Location field when this type is selected.
FileThe adapter will report all logging information to a file. The desired file must be specified in the Location field when this type has been selected.

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

Config Settings (SFTP Adapter)

The adapter 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 adapter, access to these internal properties is provided through the Other property.

SFTP Config Settings

DeleteAfterDownload:   If set to true, deletes the file after download.

This setting is used in conjunction with either Download or DownloadSingleFile. It is only applicable to the send adapter. When the send adapter is configured to download a file this setting can also be specified to delete the file from the server after it is downloaded.

DeleteOnSuspend:   Specifies whether files may be deleted from server when message is suspended.

If true, the file on the server will be deleted in accordance with the option selected in DeleteMode even if the message is suspended.

The default value is False.

DeleteOnUploadError:   Whether to delete the remote file when an error occurs after upload begins.

If an error occurs after an upload has started, the partial upload may remain on the remote server after the error is handled. If this setting is True, the send adapter will delete the partial upload while handling the error. The default value is False.

This is only applicable to the send adapter.

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, component will not send the SSH_FXP_REALPATH packet and will use the value in RemotePath directly.

Download:   If set to true, the send adapter will download files instead of upload.

This setting is used to download multiple files using the send adapter. It is only applicable to the send adapter. In situations where you want to initiate the download of files instead of using a receive adapter you can configure the send adapter to download the files. It is similar in use to DownloadSingleFile.

To do this you can not use a solicit response port. You must use a one way send port. In this case set the LocalFile setting to the directory to which you'd like to download the files.

DownloadCacheFile:   When set, only new files will be downloaded from the server.

This may be set to the location of a file on disk that will hold the names of files that were previously downloaded from the server. On each PollingInterval the adapter will check to see if the file on the server exists in this list. If the file exists in this list, it is determined that the file was previously downloaded and is not downloaded on the current polling interval. The list is automatically updated on each polling interval.

DownloadCacheFileDuration:   The number of minutes that a file name will remain in the download cache.

If a file name is added to the DownloadCacheFile and is not seen on the server again within DownloadCacheFileDuration minutes, it will be removed from the cache. This can prevent the download cache file from growing too large in certain cases.

The default value is 0, meaning that files will never be removed.

This setting is only applicable if DownloadCacheFile is set.

DownloadSingleFile:   If set to true, the send adapter will download a file instead of upload.

This setting is used to download a file from an orchestration using the send adapter. It is only applicable to the send adapter. In situations where you want to initiate the download of a file instead of using a receive adapter you can configure the send adapter to download the file.

In this case the adapter should be used as a solicit response adapter. Because a solicit response port can return only one message, you can only download one file at a time with the SFTP, SCP, FTP, and WebDAV send ports. To do this you'll need to set the DownloadSingleFile configuration setting to true. For instance: Message_2 = Message_1; Message_2(nsoftware.BizTalk.SFTP.SSHUser) = "test"; Message_2(nsoftware.BizTalk.SFTP.SSHPassword) = "test"; Message_2(nsoftware.BizTalk.SFTP.SSHHost) = "server"; Message_2(nsoftware.BizTalk.SFTP.SSHAcceptServerHostKeyAcceptAny) = true; Message_2(nsoftware.BizTalk.SFTP.RemotePath) = "temp"; Message_2(nsoftware.BizTalk.SFTP.RemoteFile) = "test.txt"; Message_2(nsoftware.BizTalk.SFTP.Other) = "DownloadSingleFile=true";

Note: You can also set DeleteAfterDownload in the Other property for FTP, SFTP, and WebDAV transfers to delete the file on the server once the download is complete. DeleteAfterDownload is not applicable to SCP. This can be done by setting one configuration setting per line in the Other property: Message_2(nsoftware.BizTalk.SFTP.Other) = "DownloadSingleFile=true\r\nDeleteAfterDownload=true";

It is also possible to download multiple files with the send adapters. To do this you can not use a solicit response port. You must use a one way send port. In this case set the LocalFile setting to the directory to which you'd like to download the files and set Download to true.

EnableFileDetailsComparison:   Whether the receive adapter should consider metadata differences when deciding whether to download a file again.

This setting is used in conjunction with DownloadCacheFile, and is only available on the receive adapter. If DownloadCacheFile is enabled, this setting can be used to control how the receive adapter uses the download file cache information when deciding whether to download a file again. (Similar to the "Enable Timestamp Comparison" property on Microsoft's FTP BizTalk Adapter.)

If this is set to False, the receive adapter will not download a file again if the cache contains any information about it (that is, if it has been downloaded before).

If this is set to True, the receive adapter will check the metadata of the remote file against its cached metadata, and will download the file again if any of the metadata differs.

ExcludeMask:   Instructs the adapter to exclude some files when downloading.

This configuration setting is used to specify a mask to exclude certain files when downloading. If a file matches both this mask and FileMask, the file will be not be downloaded.

FileMaskDelimiter:   Specifies a delimiter to use for setting multiple file masks.

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

FilePermissions:   Specifies the permissions of a file to be set after a successful upload.

This may be set to an octal value representing the permissions of a file to be set after a successful upload. For example: FilePermissions=0777 Note: When using the SCP adapter this must be a 4 digit value. The SFTP adapter will accept a 3 digit value.

IgnoreEmptyFiles:   Instructs the adapter to ignore empty files when downloading.

When this option is true the adapter will ignore any empty files when downloading from the server.

The default value is false.

Note: This is only applicable to the Receive adapter.

IgnoreFileMaskCasing:   Instructs the adapter to ignore casing of when FileMask is set.

By default the value of this setting is false. If set to true the adapter will ignore case when matching a value to the FileMask.

KeyRenegotiationThreshold:   Sets the threshold for the SSH Key Renegotiation.

This property allows you to specify the threshold, in the number of bytes, for the SSH Key Renegotiation. The default value for this property is set to 1 GB.

Example (for setting the threshold to 500 MB): SSHComponent.Config("KeyRenegotiationThreshold=524288000")

ListDirBeforeDelete:   Determines if the directory is listed before a resource is deleted.

This is True by default. When set to False the adapter will not list the directory before attempting to delete a resource. This may only be used when the exact name of the file is known and is specified in FileMask. This is helpful in situations where the name of the file is known and server permissions do not allow directory listings.

ListDirBeforeDownload:   Determines if the directory is listed on download.

This is True by default. When set to False the adapter will not list the directory before attempting a download. This may only be used when the exact name of the file is known and is specified in FileMask. This is helpful in situations where the name of the file is known and server permissions do not allow directory listings.

ListDirectory:   If set to true, the send adapter will list the directory instead of upload.

This setting is used to list the files in a remote directory on the server from an orchestration using the send adapter. It is only applicable to the send adapter. In situations where you want to list the contents of a directory you can configure the send adapter to do so.

In this case the adapter should be used as a solicit response adapter. In your orchestration after referencing the SFTP, FTP, or WebDAV adapter you can set the message context properties to configure the adapter. To specify that the adapter should list the directory set the Other property to ListDirectory=true. For instance: Message_2 = Message_1; Message_2(nsoftware.BizTalk.SFTP.SSHUser) = "test"; Message_2(nsoftware.BizTalk.SFTP.SSHPassword) = "test"; Message_2(nsoftware.BizTalk.SFTP.SSHHost) = "server"; Message_2(nsoftware.BizTalk.SFTP.SSHAcceptServerHostKeyAcceptAny) = true; Message_2(nsoftware.BizTalk.SFTP.RemotePath) = "temp"; Message_2(nsoftware.BizTalk.SFTP.RemoteFile) = "*.txt"; Message_2(nsoftware.BizTalk.SFTP.Other) = "ListDirectory=true"; The solicit response port will return a message with a body containing an XML formatted representation of the directory contents (The exact set of elements may vary depending on the adapter). For instance: <Directory name="temp"> <Directory name="subDir1"/> <Directory name="subDir2"/> <File name="file1.txt"> <Size>size</Size> <Time>time</Time> </File> <File name="file2.txt"> <Size>size</Size> <Time>time</Time> </File> <File name="file3.txt"> <Size>size</Size> <Time>time</Time> </File> </Directory>

Note: The SFTP adapter returns additional CTime and ATime elements representing the CreationTime and AccessTime. CreationTime is only supported on servers that support SFTP protocol version 4 or higher. To enable the adapter to use version 4 or higher you can set ProtocolVersion to "4".

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

This setting is only applicable 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 should contain a C# .NET style character sequence: TransferMode=1 LocalEOL=\r\ n

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

LocalFile:   Specifies the local file to upload or download.

This setting overrides the overrides the default behavior of the adapter, causing it to ignore the normal message data and upload the file indicated. Likewise, the parsed local filename is used instead of the value in the RemoteFile property.

This may also be set to a local directory when Download is set to True in the send adapter.

LogSSHPackets:   If True, detailed SSH packet logging is performed.

This setting can be enabled to assist in debugging. When set to True the adapter will include detailed information about the SSH level packets in the log. The default value is False.

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

While the SSH specification requires servers and clients to support SSH packets of at least 32000 bytes, some server implementations limit 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 an SFTP packet so that the adapter can communicate effectively with these servers. If you are having difficulty when uploading to a server, try setting MaxFileData size to value smaller than 32000.

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

MaxFilesPerPollingInterval:   The maximum number of files that will be downloaded from the server during a single poll.

By default, the adapter will download all available files (matching any filemasks) when polling the target directory. To limit the number of files that will be downloaded in a single poll, set this to the maximum number.

Note that to avoid downloading the same subset of files each poll, either DownloadCacheFile or DeleteMode should also be used.

MonitorFileGrowth:   Specifies whether the adapter checks for file growth before downloading.

If set to "TRUE" the adapter will store the file sizes of the remote files between polling intervals. If the file size does not change between polling intervals it will be downloaded and removed from the list. Otherwise it will be skipped for that interval. For example, if this option is set to TRUE, the adapter would do the following on the first two polling intervals:

Interval 1: The adapter will record the file size of the remote files.

Interval 2: The adapter will compare the recorded file size with the current file size of the remote files. If the file size has not changed then the adapter will download the file. If the file size has changed then the adapter will record the new file size but take no other actions.

ProtocolVersion:   The highest allowable SFTP version to use.

This governs the highest allowable SFTP version to use when negotiating the version with the server. The default value is 3 as 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.

RenameMode:   The condition under which RenameTo is used.

This setting controls when the value specified by RenameTo is used. If RenameTo is not specified, this setting has no impact. By default, downloaded files are only renamed after being successfully submitted to BizTalk (a value of 1). Possible values are:

1 (OnSuccess - default)The file is renamed using the value in RenameTo only after the message is successfully submitted to BizTalk.
2 (OnFailure)The file is renamed using the value in RenameTo only after the message submission to BizTalk fails.
3 (Always) The file is renamed using the value in RenameTo regardless of the message submission result.

RenameTo:   A filename to which RemoteFile will be renamed.

After downloading a file, the file on the server may be renamed using this setting. This rename action will take place after the batch submission to BizTalk. If you need to perform actions on a file before this, use the AfterGet property. This setting is used in conjunction with RenameMode to conditionally rename a file. For instance, to rename a file after it has been successfully submitted to BizTalk set the Other property of the adapter like so: RenameTo=%SourceFileName%.done Macros such as %SourceFileName% are supported as in the given example. A full list of supported macros can be found at the bottom of this section.

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

This setting is only applicable 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 should contain a C# .NET style character sequence: TransferMode=1 ServerEOL=\r\ n

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

SortCriteria:   Determines sort order before downloading files.

By default, files will be downloaded in the order in which they were listed by the server. When set to a value other than 0, this configuration setting will cause the adapter to sort the list of files before downloading. Only applies when ListDirBeforeDownload is true (default). Valid values are:

  • 0 - Disabled
  • 1 - Name, ascending
  • 2 - Name, descending
  • 3 - Date, ascending
  • 4 - Date, descending
SSHAcceptServerHostKeyFingerPrint:   Instructs the adapter to accept the server's host key with this fingerprint.

This may be set to a comma-delimited collection of 16-byte MD5 fingerprints that should be accepted as the host's key. You may supply it by HEX encoding the values in the form "0a:1b:2c:3d". Example: SSHAcceptServerHostKeyFingerprint=0a:1b:2c:3d

SSHEncryptionAlgorithms:   A comma-separated list containing all allowable compression algorithms.

During the SSH handshake, this list will be used to negotiate the encryption algorithm to be used between the client and server. This list is used for both directions: client to server and server to client.

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

aes256-cbc256-bit AES encryption in CBC mode
aes192-cbc192-bit AES encryption in CBC mode
aes128-cbc128-bit AES encryption in CBC mode
3des-cbc192-bit (3-key) triple DES encryption in CBC mode
aes256-ctr256-bit AES encryption in CTR mode
aes192-ctr192-bit AES encryption in CTR mode
aes128-ctr128-bit AES encryption in CTR mode
3des-ctr192-bit (3-key) triple DES encryption in CTR mode
cast128-cbcCAST-128 encryption
blowfish-cbcBlowfish encryption
arcfourARC4 encryption
arcfour128128-bit ARC4 encryption
arcfour256256-bit ARC4 encryption
aes256-gcm@openssh.com256-bit AES encryption in GCM mode.
aes128-gcm@openssh.com128-bit AES encryption in GCM mode.

The default value is "aes256-ctr,aes192-ctr,aes128-ctr,aes256-cbc,aes192-cbc,aes128-cbc,3des-ctr,3des-cbc,blowfish-cbc,arcfour256,arcfour128,arcfour,cast128-cbc,aes256-gcm@openssh.com,aes128-gcm@openssh.com".

SSHFingerprintHashAlgorithm:   The algorithm used to calculate the fingerprint.

This configuration setting controls which hash algorithm is used to calculate the certificate's fingerprint. Valid values are:

  • MD5 (default)
  • SHA1
  • SHA256
SSHKeyExchangeAlgorithms:   Specifies the supported key exchange algorithms.

This may be used to specify the list of supported Key Exchange algorithms used during SSH negotiation. The value should contain a comma separated list of algorithms. Supported algorithms are:

  • 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
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,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1.
SSHMacAlgorithms:   Specifies the supported Mac algorithms.

This 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:

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

This 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.

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 adapter 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 adapter will evaluate the next algorithm. Possible values are:

  • 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 adapter 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 since 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 which support them.

TemporaryDownloadExtension:   An extension to be appended during download.

During download, it may be necessary for the file on the server to be renamed. After the download is complete the file will be renamed back to the original name.

TemporaryUploadExtension:   An extension to be appended during upload.

During upload, it may be necessary for the RemoteFile to be written to a temporary file name. For example, some business process may be set up to expect a specific file extension. Using this setting will allow the adapter to upload the file without the remainder of the process attempting to pick up the incomplete file.

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 adapter 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 adapter will automatically determine the value for ServerEOL if the server supports the "newline" protocol extension.

WaitForServerDisconnect:   Causes the component to wait for the server to close the connection.

When this is set to True, the adapter will wait for the server to close the connection after operation is complete instead of closing the connection immediately. This helps prevent ports on the system from being left in the TIME_WAIT state. The default is False.

General Config Settings

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

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

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

The LocalHost configuration 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 adapter initiate connections (or accept in the case of server adapters) only through that interface.

If the adapter is connected, the LocalHost configuration 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).

TcpNoDelay:   Whether or not to delay when sending packets.

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

By default, this config is set to false.

UseInternalSecurityAPI:   Tells the adapter whether or not to use the system security libraries or an internal implementation.

By default the adapter will use the system security libraries to perform cryptographic functions where applicable. When set to False calls to unmanaged code will be made. In certain environments this is not desirable. To use a completely managed security implementation set this setting to True. Setting this to True tells the adapter to use the internal implementation instead of using the system's security API.

Note: This setting is static. The value set is applicable to all adapters used in the application.

When this value is set the product's system DLL is no longer required as a reference, as all unmanaged code is stored in that file.

Supported Macros

The adapter also supports the following Macros. These values are not case sensitive and would be supplied to a property in the form %MacroName%.

TempThis is resolved to the full path to the system's temporary directory.
MessageIDGlobally unique identifier (GUID) of the message in BizTalk Server.
SourceFileNameThe original file name. This includes the extension and excludes the file path, for example, Sample.xml
SourceFileNameNoExtThe original file name without the extension or file path, for example, Sample
RemoteFileNameThe name of the file as it was uploaded to the remote server. This includes the extension and excludes the file path, for example, Sample.xml. Valid only for AS3, FTP, and SFTP Send Adapters.
DestinationPartyName of the destination party.
DestinationPartyQualifierQualifier of the destination party.
SourcePartyName of the source party.
SourcePartyQualifierQualifier of the source party.
DateTime:CustomFormatThis special value allows you to specify your own custom time format. For instance DateTime:yyyy would be resolved to the 4 digit year.
DateThe date format yyyy-MM-dd.
DateTimeThe date format yyyy-MM-ddThhmmss.
TimeThe date format hhmmss.
DateTime_BTS2000The date format yyyyMMddhhmmssf.
DateTime.TZThe date format yyyy-MM-ddThhmmsszzz.
Time.TZThe date format hhmmsszzz.
Property#<Schema>#<Name>This special value allows you to include a property from the incoming message. For instance "PROPERTY#http://schemas.microsoft.com/BizTalk/2003/system-properties#ReceivePortName" would resolve to the ReceivePortName property of the message.
