ShellPrompt Property (Telnet Task)

The shell prompt of the telnet session.

Data Type

String

Default Value

">"

Remarks

This property specifies the shell prompt to wait for when executing a command. After a command is sent to the server the task will search the response for the prompt defined in this property to signal that the command execution is complete. If the ShellPrompt is not found within Timeout seconds an error occurs.

This value is case sensitive.

The default value is ">".

ShellPromptExpression Property (Telnet Task)

A regular expression to match the shell prompt returned by the server.

Data Type

String

Default Value

""

Remarks

This property specifies a regular expression defining a pattern of shell prompt to wait for when executing a command. After a command is sent to the server the task will search the response for a prompt matching the expression defined in this property to signal that the command execution is complete.

This may be used in place of ShellPrompt and is helpful in situations where the exact prompt is not known but a general format is defined. If a matching prompt is not found within Timeout seconds an error occurs.

Note: The value specified in ShellPromptExpression must be a properly formatted .NET regular expression.

SSLAcceptServerCert Property (Telnet Task)

Instructs the component to unconditionally accept the server certificate that matches the supplied certificate.

Data Type

Certificate

Remarks

If it finds any issues with the certificate presented by the server, the task will normally terminate the connection with an error. You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

This property is used to set a Public Key Certificate.

Ordinarily, the system will attempt to locate the public key in trusted certificate stores in the system registry. If a match is found, the certificate is trusted, and the process proceeds without error. If the certificate is not trusted, the task will report an error.

You may explicitly set a public key, either to accept a key that is not installed on the system, or to ensure that a specific key is presented. Public key certificates may be loaded from the machine registry or from file. If you click on the ellipses, a certificate selection dialog will open. To select a public key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of available certificates will be shown below.

Alternatively, you may specify a public key on file. Select the PEM or Certificate File tabs to load a public key from file. You can use the browse button to examine the file system for the certificate that you wish to use. Public keys typically are stored in .CER, .DER, or .PEM files, but other formats may be used. You can click on the Open button to examine the contents of the certificate. Or, if you have a certificate stored in memory, you can write the contents of the certificate into the text box provided. Note that if you are loading a certificate from memory, the certificate must be Base-64 encoded, or the string representation of the certificate may become corrupted and uninterpretable.

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

Note: You may also set SSLAcceptServerCertAcceptAny to True without opening the certificate selection dialog to force the task to unilaterally authenticate any server during the security handshake. It is strongly recommended that you use this only for testing purposes.

SSLAcceptServerCertAcceptAny Property (Telnet Task)

Tells the component to accept any server certificate.

Data Type

Boolean

Default Value

false

Remarks

When set to true, the task will unilaterally authenticate any server during the security handshake. It is strongly recommended that you use this only for testing purposes.

SSLCert Property (Telnet Task)

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

Data Type

Certificate

Remarks

This property is used to assign a specific certificate for SSL 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 task will attempt to verify that certificate selection. If successful, the subject of the certificate will be displayed in the property field. If the task was not able to verify the selection, a dialog box will appear instead detailing the verification error.

SSLStartMode Property (Telnet Task)

Determines how the component starts the SSL negotiation.

Data Type

Enumeration

Possible Values

Automatic (0)
Implicit (1)
Explicit (2)
None (3)

Default Value

3

Remarks

The SSLStartMode property may have one of the following values:

The default value is None.

Timeout Property (Telnet Task)

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 task will wait for the operation to complete before returning control.

If Timeout expires, and the operation is not yet complete, the task 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 task may be changed to absolute timeouts, i.e. the task 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).

User Property (Telnet Task)

The username to use for authentication.

Data Type

String

Default Value

""

Remarks

This property specifies the username used during authentication.

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

Firewall Type

The firewall the component will connect through.

Remarks

When connecting through a firewall, this type is used to specify different properties of the firewall such as the firewall Host and the FirewallType.

Fields

Config Settings (Telnet Task)

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