Connect to Unix using ssh and sftp via Java [RSA S

问题:

I need to connect to Unix Server using Java via SSH and SFTP protocol and execute specific commands and do File Transfers also. But there is RSA token authentication is enabled on Unix. So I need to get the current RSA token password at run time also along with User's Password. So how to get this done via Java? Is there any Java API for this?

FYI, Unix Login steps using putty :

1. connect using Server IP.
2. List item
3. give User Name.
4. give Password
5. give the 6 digit SecurID generated Number.

This sounds like keyboard-interactive authentication. In this authentication mechanism the server asks user a question, to which the user must respond. Any number of questions is possible and their order is defined by the server.

Keyboard-interactive authentication is used by many servers, but it's usually reduced to asking for a password, so most software which claims support for this authentication method will just put a password as the answer and that's all.

I don't know if free Java libraries support keyboard-interactive authentication with multiple questions. Our SecureBlackbox classes have an event which passes questions to the application, and the application can either provide an answer itself or ask the human operator to provide the answer.
