Port NULL¶

Stimulation¶

This port has no stimulus capabilities.

Properties 🛈¶

Name	Available if	Default value	Valid values	Type	Description
SSH host				uri	Host address
SSH port		22		int	Host port
SSH username				string	Username for the authentication.
Authentication method		Keyfile	[None, Password, Keyfile] Display values: None: Without authentication Password: Password Keyfile: Private key file	string	Method used to log into the remote system.
SSH key path	Authentication method: ‘Keyfile’			string	Path to the SSH private key for public key authentication. Can be specified absolute or relative to the tool host base path. If no tool host base path is set, the path can be relative to the workspace. Supported key formats: RSA, DSA, ECDSA and ED25519
SSH password	Authentication method: ‘Password’			string	Password of the specified user. Attention: The password is stored unencrypted in the TBC!
Connection mode		Auto	[Auto, Manual] Display values: Auto: Connect automatically Manual: Connect manually via port job call	string	Defines whether the SSH connection is established automatically or manually via port job.
File transfer protocol		SFTP	[SFTP, SCP]	string	Sets the protocol used to transfer files. If possible, SFTP should be preferred because it is the more stable and secure protocol.

Jobs 🛈¶

Connect¶

Establishes the SSH connection. If the connection is already established, no action is performed.

Disconnect¶

Terminates the SSH connection. If the connection is already disconnected, no action is performed.

DownloadFileOrFolder¶

Copies a file or folder from the remote PC to the local machine.

Existing files will be overwritten.

Parameter

Name	Available if	Default value	Valid values	Type	Description
localPath				string	Local path to which the remote files are copied. Will be created if necessary.
remotePath				string	File or folder on the remote PC being copied.

ExecuteInteractively¶

Note: Only supported for SSH hosts with a Linux distribution.

Runs the specified expression in an interactive session, waits for the output generated from it, and returns it. Unlike the ExecuteSshCommand job, all calls of this job act in the same shell; the context (e.g. set environment variables, current working directory) is preserved over all calls. The shell is closed at test case end.

This job is blocking and returns under these conditions:

The command was executed completely (successful or with error).
A configurable string is found in the SSH output (e.g. “password” for command “sudo pwd”).
The entire call takes longer than an adjustable timeout. In this case an error will be raised.

In the first two cases, the previously generated output lines of the SSH shell are returned.

Parameter

Name	Default value	Type	Description
command		string	Command to be executed on the remote PC.
returnAtText		string	Abort condition for case 2). If not empty, the SSH output will be searched for this string and if present, the job call will be terminated.
timeout	30	int	Abort condition for case 3). Causes an error if the call is not finished after the specified time in seconds.

Return value

Name	Available if	Default value	Valid values	Type	Description
result				object	List of all rows of SSH shell output that result from the given input.

ExecuteSshCommand¶

Executes a command via SSH on the remote PC.

Parameter

Name	Available if	Default value	Valid values	Type	Description
command				string	Command to be executed on the remote PC. The command is executed in a separate session, which is closed again after the call. Multiple calls of the job are therefore independent of each other. The command is executed in an environment that is neither interactive nor a login shell. Therefore no shell environment variables are loaded.
nonBlocking		False	[False, True]	bool	If True, the job call returns immediately and returns only empty lists for stdout and stderr.

Return value

Name	Available if	Default value	Valid values	Type	Description
result				object	Tuple, containing the two standard data streams stdout and stderr. For each stream, the tuple contains a list of all corresponding lines.

IsConnected¶

Returns if the SSH connection is established.

Return value

Name	Available if	Default value	Valid values	Type	Description
result			[False, True]	bool

UploadFileOrFolder¶

Copies a file or folder from the local machine to the remote PC.

Existing files will be overwritten.

Parameter

Name	Available if	Default value	Valid values	Type	Description
localPath				string	File or folder on the local PC being copied.
remotePath				string	Remote path to which the local files are copied. Will be created if necessary.
