twisted.conch.scripts.tkconch.SSHUserAuthClient

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	Return a public key for the user. If no more public keys are available, return `None`.
Method	getPrivateKey	Return a `Deferred` that will be called back with the private key object corresponding to the last public key from getPublicKey(). If the private key is not available, errback on the Deferred.
Method	_cbGetPrivateKey	Undocumented

Inherited from SSHUserAuthClient:

Instance Variable	name	the name of this service: 'ssh-userauth' (type: `str`)
Instance Variable	preferredOrder	a list of authentication methods that should be used first, in order of preference, if supported by the server (type: `list`)
Instance Variable	user	the name of the user to authenticate as (type: `bytes`)
Instance Variable	instance	the service to start after authentication has finished (type: `service.SSHService`)
Instance Variable	authenticatedWith	a list of strings of authentication methods we've tried (type: `list` of `bytes`)
Instance Variable	triedPublicKeys	a list of public key objects that we've tried to authenticate with (type: `list` of `Key`)
Instance Variable	lastPublicKey	the last public key object we've tried to authenticate with (type: `Key`)
Method	__init__	Undocumented
Method	serviceStarted	called when the service is active on the transport.
Method	askForAuth	Send a MSG_USERAUTH_REQUEST.
Method	tryAuth	Dispatch to an authentication method.
Method	ssh_USERAUTH_SUCCESS	We received a MSG_USERAUTH_SUCCESS. The server has accepted our authentication, so start the next service.
Method	ssh_USERAUTH_FAILURE	We received a MSG_USERAUTH_FAILURE. Payload:: string methods byte partial success
Method	ssh_USERAUTH_PK_OK	This message (number 60) can mean several different messages depending on the current authentication type. We dispatch to individual methods in order to handle this request.
Method	ssh_USERAUTH_PK_OK_publickey	This is MSG_USERAUTH_PK. Our public key is valid, so we create a signature and try to authenticate with it.
Method	ssh_USERAUTH_PK_OK_password	This is MSG_USERAUTH_PASSWD_CHANGEREQ. The password given has expired. We ask for an old password and a new password, then send both back to the server.
Method	ssh_USERAUTH_PK_OK_keyboard_interactive	This is MSG_USERAUTH_INFO_RESPONSE. The server has sent us the questions it wants us to answer, so we ask the user and sent the responses.
Method	auth_publickey	Try to authenticate with a public key. Ask the user for a public key; if the user has one, send the request to the server and return True. Otherwise, return False.
Method	auth_password	Try to authenticate with a password. Ask the user for a password. If the user will return a password, return True. Otherwise, return False.
Method	auth_keyboard_interactive	Try to authenticate with keyboard-interactive authentication. Send the request to the server and return True.
Method	signData	Sign the given data with the given public key.
Method	getGenericAnswers	Returns a `Deferred` with the responses to the promopts.
Method	_ebAuth	Generic callback for a failed authentication attempt. Respond by asking for the list of accepted methods (the 'none' method)
Method	_cbUserauthFailure	Undocumented
Method	_cbSignedData	Called back out of self.signData with the signed data. Send the authentication request with the signature.
Method	_setOldPass	Called back when we are choosing a new password. Simply store the old password for now.
Method	_setNewPass	Called back when we are choosing a new password. Get the old password and send the authentication message with both.
Method	_cbGenericAnswers	Called back when we are finished answering keyboard-interactive questions. Send the info back to the server in a MSG_USERAUTH_INFO_RESPONSE.
Method	_cbGetPublicKey	Undocumented
Method	_cbPassword	Called back when the user gives a password. Send the request to the server.
Method	_cbSignData	Called back when the private key is returned. Sign the data and return the signature.

Inherited from SSHService (via SSHUserAuthClient):

Method	serviceStopped	called when the service is stopped, either by the connection ending or by another service being started
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

def getPassword(self, prompt=None):

overrides twisted.conch.ssh.userauth.SSHUserAuthClient.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: '.

Returns (type: defer.Deferred)

def getPublicKey(self):

overrides twisted.conch.ssh.userauth.SSHUserAuthClient.getPublicKey

Return a public key for the user. If no more public keys are available, return None.

This implementation always returns None. Override it in a subclass to actually find and return a public key object.

Returns (type: Key or None)

def getPrivateKey(self):

overrides twisted.conch.ssh.userauth.SSHUserAuthClient.getPrivateKey

Return a Deferred that will be called back with the private key object corresponding to the last public key from getPublicKey(). If the private key is not available, errback on the Deferred.

Returns (type: Deferred called back with Key)

def _cbGetPrivateKey(self, ans, count):
