Java Authentication

[stu78]

Hi,

I need to write a java applet which runs a unix script. However first in order to run the script I need to authenticate to a particular server with a users User Name & password.

How can I do this?

Basically - I need to log into a server with username & password, then kick off a script?

Thanks,
Stu

>>> I need to log into a server with username & password

How ? rlogin, telnet, ssh ...
Why can't the unix script do this section for you ?

>>> authenticate to a particular server
Using what method ?

Hi sedj,

I need to write a telnet client in Java I think. Do you know where I can get examples of how to do this?

Sorry - the original mail was unclear - however my requirements are clear now. Basically I need to run unix commands from a java applet, however i need also to be able to connect to the host etc. to do this....

There is a complete telnet applet (with source) at :

http://javassh.org/

From which you should be able to use f.ex. "TelnetWrapper" like in the following piece of code :
(I have no access to a Unix host, so I haven't tried it yet. If needed I can maybe telnet to an AS/400)

import java.io.*;
import de.mud.telnet.*;

public class TelnetExample {

  public TelnetExample() {
  }

  public static void main(String args[]) {
    TelnetWrapper telnet = new TelnetWrapper();
    try {
      telnet.connect(args[0], 23);
      telnet.login("stu","***");
      telnet.setPrompt("/users/stu ->");
      telnet.waitfor("TERM =");
      telnet.send("dumb");
      System.out.println(telnet.send("ls -l"));
      } catch(IOException e) {
        e.printStackTrace();
      }
    }
}
