labgrid.util.ssh module

class labgrid.util.ssh.SSHConnection(host)

Bases: object

SSHConnections are individual connections to hosts managed by a control socket. In addition to command execution this class also provides an interface to manage port forwardings. These are used in the remote infrastructure to tunnel multiple connections over one SSH link.

A public identity infrastructure is assumed, no extra username or passwords are supported.

__attrs_post_init__()

get_prefix()

run(command, *, codec='utf-8', decodeerrors='strict', force_tty=False, stderr_merge=False, stderr_loglevel=None, stdout_loglevel=None)

Run a command over the SSHConnection

Parameters

• command (string) – The command to run

• codec (string, optional) – output encoding. Defaults to “utf-8”.

• decodeerrors (string, optional) – behavior on decode errors. Defaults to “strict”. Refer to stdtypes’ bytes.decode for details.

• force_tty (bool, optional) – force allocate a tty (ssh -tt). Defaults to False

• stderr_merge (bool, optional) – merge ssh subprocess stderr into stdout. Defaults to False.

• stdout_loglevel (int, optional) – log stdout with specific log level as well. Defaults to None, i.e. don’t log.

• stderr_loglevel (int, optional) – log stderr with specific log level as well. Defaults to None, i.e. don’t log.

Returns

(stdout, stderr, returncode)

run_check(command, *, codec='utf-8', decodeerrors='strict', force_tty=False, stderr_merge=False, stderr_loglevel=None, stdout_loglevel=None)

Runs a command over the SSHConnection returns the output if successful, raises ExecutionError otherwise.

Except for the means of returning the value, this is equivalent to run.

Parameters

• command (string) – The command to run

• codec (string, optional) – output encoding. Defaults to “utf-8”.

• decodeerrors (string, optional) – behavior on decode errors. Defaults to “strict”. Refer to stdtypes’ bytes.decode for details.

• force_tty (bool, optional) – force allocate a tty (ssh -tt). Defaults to False

• stderr_merge (bool, optional) – merge ssh subprocess stderr into stdout. Defaults to False.

• stdout_loglevel (int, optional) – log stdout with specific log level as well. Defaults to None, i.e. don’t log.

• stderr_loglevel (int, optional) – log stderr with specific log level as well. Defaults to None, i.e. don’t log.

Returns

stdout of the executed command if successful and

otherwise an ExecutionError Exception

Return type

List[str]

get_file(remote_file, local_file)

Get a file from the remote host

put_file(local_file, remote_path)

forward command

remove_port_forward(remote_host, remote_port)

cancel command

add_remote_port_forward(remote_port, local_port, remote_bind=None)

remote forward command

Note that the remote socket is not bound to any specific IP by default, making it reachable by the target. Also, ‘GatewayPorts clientspecified’ needs to be configured in the remote host’s sshd_config.

remove_remote_port_forward(remote_port, local_port, remote_bind=None)

remote cancel command
