Class KeyboardInteractiveAuthentication

java.lang.Object
  com.maverick.sshd.auth.KeyboardInteractiveAuthentication

All Implemented Interfaces:

com.maverick.ssh.components.SshComponent, AuthenticationMechanism

public class KeyboardInteractiveAuthentication
extends Object
implements AuthenticationMechanism

Field Summary

static String	AUTHENTICATION_METHOD
protected Connection	con
static int	SSH_MSG_USERAUTH_INFO_REQUEST
static int	SSH_MSG_USERAUTH_INFO_RESPONSE

Constructor Summary

KeyboardInteractiveAuthentication(org.apache.mina.core.session.IoSession session, SshTransport transport, AuthenticationProtocol authentication, Connection con, KeyboardInteractiveProvider kbi)

Method Summary

String	getName() Return the SSH method name for this authentication.
org.apache.mina.core.session.IoSession	getSession()
SshTransport	getTransport()
boolean	isPassword() Is this password authentication? We use this so user does not end up having to submit their password if an alternative method provides password authentication but is not the core "password" method (for example keyboard-interactive).
boolean	processMessage(byte[] msg) If the SSH protocol authentication method defines additional messages which are sent from the client, they will be passed into your implementation here when received.
boolean	startRequest(String username, byte[] msg) Start an authentication transaction.

Method Detail

getName

public String getName()

Description copied from interface: AuthenticationMechanism

Return the SSH method name for this authentication. e.g "password"

Specified by:

getName in interface com.maverick.ssh.components.SshComponent

Specified by:

getName in interface AuthenticationMechanism

Returns:

String

getTransport

public SshTransport getTransport()

processMessage

public boolean processMessage(byte[] msg)
                       throws IOException

Description copied from interface: AuthenticationMechanism

If the SSH protocol authentication method defines additional messages which are sent from the client, they will be passed into your implementation here when received.

Specified by:

processMessage in interface AuthenticationMechanism

Returns:

boolean

Throws:

IOException

startRequest

public boolean startRequest(String username,
                            byte[] msg)
                     throws IOException

Description copied from interface: AuthenticationMechanism

Start an authentication transaction. If the authentication mechanism is simple and you can determine the result from all information received in the SSH_MSG_USERAUTH_REQUEST message, you should call the approriate completion methods on the AuthenticationProtocol instance that was passed in the initialization process. The request data varies according to the authentication method.

 if (success)
   authentication.completedAuthentication(method, username, service);
 else
   authentication.failedAuthentication(method);
 

Specified by:

startRequest in interface AuthenticationMechanism

msg - the request data from the SSH_MSG_USERAUTH_REQUEST message

Returns:

true if the message was processed, otherwise false

Throws:

IOException

getSession

public org.apache.mina.core.session.IoSession getSession()

isPassword

public boolean isPassword()

Description copied from interface: AuthenticationMechanism

Is this password authentication? We use this so user does not end up having to submit their password if an alternative method provides password authentication but is not the core "password" method (for example keyboard-interactive).

Specified by:

isPassword in interface AuthenticationMechanism

Returns:
