Help needed with Apache SSHD

[Sadhani, Girish (NSN - IN/Bangalore)]

Hello All,

I am trying to setup a SSH Server using Apache SSHD. I tried using the
quick SSH server setup as suggested in the Apache SSHD documentation:

http://mina.apache.org/sshd/embedding-sshd-in-5-minutes.html

My code :


import java.io.IOException;
import java.io.OutputStream;
import java.net.ServerSocket;

import org.apache.mina.core.session.IoSession;
import org.apache.sshd.SshServer;
import org.apache.sshd.common.AbstractSessionIoHandler;
import org.apache.sshd.common.keyprovider.FileKeyPairProvider;
import org.apache.sshd.server.PasswordAuthenticator;
import org.apache.sshd.server.SessionFactory;
import org.apache.sshd.server.CommandFactory.ExitCallback;
import org.apache.sshd.server.ShellFactory.Shell;
import org.apache.sshd.server.command.ScpCommand;
import org.apache.sshd.server.command.ScpCommandFactory;
import
org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider;
import org.apache.sshd.server.shell.ProcessShellFactory;



public class Main {
        
        public static SshServer sshd = null;
        
        public static SessionFactory sessFactory =null;
        
        public static IoSessionImpl ioSession = null;
        public static ProcessShellFactory shell = null;
        
        
        public static void main(String[] args) throws
InterruptedException, IOException {
                
        
                SshServer sshd = SshServer.setUpDefaultServer();
                sshd.setPort(22);
                sshd.setKeyPairProvider(new
SimpleGeneratorHostKeyProvider("hostkey.ser"));
                //sshd.setShellFactory(new ProcessShellFactory(new
String[] { "/usr/bin/login", "-f", "-h", "localhost", "$USER",
"/bin/sh", "-i" }));
                sshd.setShellFactory(new ProcessShellFactory(new
String[] { "/bin/sh", "-i", "-l" }));
                //sshd.setPasswordAuthenticator(new
PAMPasswordAuthenticator());
                sshd.setPasswordAuthenticator(new
PasswordAuthenticator() {
                                                public Object
authenticate(String username, String password) {
                                         return (username != null &&
username.equals(password)) ? username : null;
                                }

                                
                });
                sshd.start();

                

        }

}

I am trying to do this on my PC, config is :

> Windows XP
> Pentium 4


The problem is that when I try to login using PuTTY, the shell exits
after the prompt for username and password !! I tried debugging this, I
saw that it comes to the authenticate procedure, after which it the
PuTTY shell exits without any error message.

Any help will be greatly appreciated.

Thanks & Regards,
Girish. S. Sadhani
