No class docstring
Method __init__ Undocumented
Method serviceStarted called when the service is active on the transport.
Method serviceStopped called when the service is stopped, either by the connection ending or by another service being started
Method getPassword Return a Deferred that will be called back with a password. prompt is a string to display for the password, or None for a generic 'user@hostname's password: '.
Method getPublicKey Get a public key from the key agent if possible, otherwise look in the next configured identity file for one.
Method signData Extend the base signing behavior by using an SSH agent to sign the data, if one is available.
Method getPrivateKey Try to load the private key from the last used file identified by getPublicKey, potentially asking for the passphrase if the key is encrypted.
Method getGenericAnswers Returns a Deferred with the responses to the promopts.
Method _setAgent Undocumented
Method _ebSetAgent Undocumented
Method _getPassword Prompt for a password using getpass.getpass.
Class Method _openTty Open /dev/tty as two streams one in read, one in write mode, and return them.
Class Method _replaceStdoutStdin Contextmanager that replaces stdout and stdin with /dev/tty and resets them when it is done.

Inherited from SSHService (via SSHUserAuthClient):

Method logPrefix Override this method to insert custom logging behavior. Its return value will be inserted in front of every line. It may be called more times than the number of output lines.
Method packetReceived called when we receive a packet on the transport

Undocumented
def _getPassword(self, prompt): (source)

Prompt for a password using getpass.getpass.

ParameterspromptWritten on tty to ask for the input. (type: str)
ReturnsThe input. (type: str)
def getPassword(self, prompt=None): (source)

Return a Deferred that will be called back with a password. prompt is a string to display for the password, or None for a generic 'user@hostname's password: '.

Returns (type: defer.Deferred)
def getPublicKey(self): (source)

Get a public key from the key agent if possible, otherwise look in the next configured identity file for one.

def signData(self, publicKey, signData): (source)

Extend the base signing behavior by using an SSH agent to sign the data, if one is available.

def getPrivateKey(self): (source)

Try to load the private key from the last used file identified by getPublicKey, potentially asking for the passphrase if the key is encrypted.

def getGenericAnswers(self, name, instruction, prompts): (source)

Returns a Deferred with the responses to the promopts.

ParametersnameThe name of the authentication currently in progress.
instructionDescribes what the authentication wants.
promptsA list of (prompt, echo) pairs, where prompt is a string to display and echo is a boolean indicating whether the user's response should be echoed as they type it.
@classmethod
def _openTty(cls): (source)

Open /dev/tty as two streams one in read, one in write mode, and return them.

ReturnsFile objects for reading and writing to /dev/tty, corresponding to standard input and standard output. (type: A tuple of io.TextIOWrapper on Python 3. A tuple of binary files on Python 2.)
@classmethod
@contextlib.contextmanager
def _replaceStdoutStdin(cls): (source)

Contextmanager that replaces stdout and stdin with /dev/tty and resets them when it is done.
