Examples of com.sshtools.j2ssh.SshClient.authenticate()

com.sshtools.j2ssh.SshClient.authenticate()

Authenticate the user on the remote host.

To authenticate the user, create an SshAuthenticationClient instance and configure it with the authentication details.
PasswordAuthenticationClient pwd = new PasswordAuthenticationClient(); pwd.setUsername("root"); pwd.setPassword("xxxxxxxxx"); int result = ssh.authenticate(pwd);
The method returns a result value will one of the public static values defined in AuthenticationProtocolState. These are

COMPLETED - The authentication succeeded.
PARTIAL - The authentication succeeded but a further authentication method is required.
FAILED - The authentication failed.
CANCELLED - The user cancelled authentication (can only be returned when the user is prompted for information.
