class documentation

class FakeClockSSHUserAuthServer(SSHUserAuthServer): (source)

Undocumented

Property	`attemptsBeforeDisconnect`	Use the `attemptsBeforeDisconnect` value defined by the factory to make it easier to override.
Property	`clock`	Use the reactor defined by the factory, rather than the default global reactor, to simplify testing (by allowing an alternate implementation to be supplied by tests).

Inherited from SSHUserAuthServer:

Method	`auth_password`	Password authentication. Payload:
Method	`auth_publickey`	Public key authentication. Payload:
Method	`serviceStarted`	Called when the userauth service is started. Set up instance variables, check if we should allow password authentication (only allow if the outgoing connection is encrypted) and set up a login timeout.
Method	`serviceStopped`	Called when the userauth service is stopped. Cancel the login timeout if it's still going.
Method	`ssh_USERAUTH_REQUEST`	The client has requested authentication. Payload:
Method	`timeoutAuthentication`	Called when the user has timed out on authentication. Disconnect with a DISCONNECT_NO_MORE_AUTH_METHODS_AVAILABLE message.
Method	`tryAuth`	Try to authenticate the user with the given method. Dispatches to a auth_* method.
Instance Variable	`authenticatedWith`	a list of authentication methods that have already been used.
Instance Variable	`interfaceToMethod`	a `dict` mapping credential interfaces to authentication methods. The server checks to see which of the cred interfaces have checkers and tells the client that those methods are valid for authentication.
Instance Variable	`loginAttempts`	the number of login attempts that have been made
Instance Variable	`loginTimeout`	the number of seconds we wait before disconnecting the user for taking too long to authenticate
Instance Variable	`method`	the current authentication method
Instance Variable	`name`	the name of this service: 'ssh-userauth'
Instance Variable	`nextService`	the service the user wants started after authentication has been completed.
Instance Variable	`passwordDelay`	the number of seconds to delay when the user gives an incorrect password
Instance Variable	`portal`	the `twisted.cred.portal.Portal` we are using for authentication
Instance Variable	`supportedAuthentications`	A list of the supported authentication methods.
Instance Variable	`user`	the last username the client tried to authenticate with
Method	`_cbFinishedAuth`	The callback when user has successfully been authenticated. For a description of the arguments, see `twisted.cred.portal.Portal.login`. We start the service requested by the user.
Method	`_ebBadAuth`	The final errback in the authentication chain. If the reason is error.IgnoreAuthentication, we simply return; the authentication method has sent its own response. Otherwise, send a failure message and (if the method is not 'none') increment the number of login attempts.
Method	`_ebCheckKey`	Called back if the user did not sent a signature. If reason is error.ValidPublicKey then this key is valid for the user to authenticate with. Send MSG_USERAUTH_PK_OK.
Method	`_ebMaybeBadAuth`	An intermediate errback. If the reason is error.NotEnoughAuthentication, we send a MSG_USERAUTH_FAILURE, but with the partial success indicator set.
Method	`_ebPassword`	If the password is invalid, wait before sending the failure in order to delay brute-force password guessing.
Class Variable	`_log`	Undocumented
Instance Variable	`_cancelLoginTimeout`	Undocumented

Inherited from SSHService (via SSHUserAuthServer):

Method	`logPrefix`	Undocumented
Method	`packetReceived`	called when we receive a packet on the transport
Class Variable	`protocolMessages`	Undocumented
Class Variable	`transport`	Undocumented
