com.jscape.inet.ssh.authentication.requests
Class UserDataBasedRequest

java.lang.Object
  com.jscape.util.task.AbstractTask
      com.jscape.inet.ssh.authentication.requests.UserDataBasedRequest

All Implemented Interfaces:

AuthenticationRequest, Task, java.lang.Cloneable, java.lang.Runnable

public class UserDataBasedRequest
extends com.jscape.util.task.AbstractTask
implements AuthenticationRequest

This complex request tries to authenticate the user basing on available user information: if user data contains key pair it tries to perform "publickey" authentication. If that fails it tries to perform "password" method. If that fails this request tries to perform "keyboard-interactive" method with assumption that server asks only for user password.
