static argparser_add_default_command_line_arguments(argparser)

Extend argparser with DirectorConsole specific parameter.

Every command line program must offer a similar set of parameter to connect to a Bareos Director. This method adds the required parameter to an existing ArgParser instance. Parameter required to initialize a DirectorConsole class are stored in variables prefixed with BAREOS_.

Use bareos.bsock.lowlevel.LowLevel.argparser_get_bareos_parameter() to retrieve the relevant parameter (with the BAREOS_ prefix removed).

Example

>>> argparser = argparse.ArgumentParser(description="Console to Bareos Director.")
>>> DirectorConsole.argparser_add_default_command_line_arguments(argparser)
>>> args = argparser.parse_args()
>>> bareos_args = DirectorConsole.argparser_get_bareos_parameter(args)
>>> director = DirectorConsole(**bareos_args)

Parameters:

argparser (ArgParser or ConfigArgParser) – (Config)ArgParser instance.

static argparser_get_bareos_parameter(args)

Extract arguments.

This method is usually used together with the method argparser_add_default_command_line_arguments().

Parameters:

args (ArgParser.Namespace) – Arguments retrieved by ArgumentParser.parse_args().

Returns:

The relevant parameter from args to initialize a connection.

Return type:

dict

auth()

Login to a Bareos Daemon.

Returns:

True, if the authentication succeeds. In earlier versions, authentication failures returned False. However, now an authentication failure raises an exception.

Return type:

bool

Raises:

bareos.exceptions.AuthenticationError – if authentication fails.

call(command)

Call a Bareos command.

Parameters:

command (str or list) – Command to execute. Best provided as a list.

Returns:

Result received from the Daemon.

Return type:

bytes

close()

Close the connection.

connect(address, port, dirname, connection_type, name=None, password=None, timeout=None)

Establish a network connection and authenticate.

Parameters:

• address (str) – Address of the Bareos Director (hostname or IP).

• port (int) – Port number of the Bareos Director.

• dirname (str, optional) – Name of the Bareos Director. Deprecated, normally not required.

• connection_type (int) – See bareos.bsock.connectiontype.ConnectionType.

• name (str, optional) – Credential name.

• password (str, bareos.util.Password) – Credential password, in cleartext or as Password object.

• timeout (int, optional) – Connection timeout in seconds. Default OS specific.

Returns:

True, if the authentication succeeds. In earlier versions, authentication failures returned False. However, now an authentication failure raises an exception.

Return type:

bool

Raises:

• bareos.exceptions.ConnectionError – If connection can be established.

• bareos.exceptions.PamAuthenticationError – If PAM authentication fails.

• bareos.exceptions.AuthenticationError – If Bareos authentication fails.

get_cipher()

If a encrypted connection is used, returns information about the encryption. Else it returns None.

Returns:

Returns a three-value tuple containing the name of the cipher being used, the version of the SSL protocol that defines its use, and the number of secret bits being used. If the connection is unencrypted or has been established, returns None.

Return type:

tuple or None

get_protocol_version()

Returns:

Number that represents the Bareos Console protocol version (see bareos.bsock.protocolversions.ProtocolVersions.)

Bareos TLS-PSK excepts the identity is a specific format.

has_data()

Is readable data available?

True: if readable data is available.

Return type:

bool

interactive()

Enter the interactive mode.

Exit via typing “exit” or “quit”.

Returns:

True, if exited by user command.

Only used during in the authentication phase.

Returns:

(code, text).

Return type:

Tries to reconnect.

Returns:

True, if the connection could be reestablished.

Return type:

bool

recv()

This is, header (4 bytes): if

• > 0: length of the following message

• < 0: Bareos signal

Returns:

Message retrieved via the connection.

Return type:

bytearray

Raises:

bareos.exceptions.SignalReceivedException – If a Bareos signal is received.

recv_bytes(length, timeout=10)

Receive a number of bytes.

Parameters:

• length (int) – Number of bytes to receive.

• timeout (float) – Timeout in seconds.

Raises:

• bareos.exceptions.ConnectionLostError – If the socket connection gets lost.

• socket.timeout – If a timeout occurs on the socket connection, meaning no data received.

recv_msg(regex=b'^\\d\\d\\d\\d OK.*$')

Receive a full message.

It retrieves messages (header + message text), until

1. the message contains the specified regex or

2. the header indicates a signal.

Parameters:

regex (bytes) – Descripes the expected end of the message.

Returns:

Message retrieved via the connection.

Return type:

bytearray

Raises:

bareos.exceptions.SignalReceivedException – If a Bareos signal is received.

Returns:

Retrieved message.

Return type:

bytearray

send(msg=None)
