            Bug ID: 2099
           Summary: SshClient.connect() failure on port 22
    Classification: Unclassified
           Product: Portable OpenSSH
           Version: -current
          Hardware: Sparc
                OS: SunOS
            Status: NEW
          Severity: critical
          Priority: P5
         Component: ssh

We are facing SFTP connection issue with the metod
SshClient.connect(IP,22) on port 22. This is happening only on few
machines, but SFTP through putty will establish connection to the
server successfully. We are using a simple stand alone program to
connect using sftp protocol. 

SSH Version:
bash-3.2$ ssh -V
Sun_SSH_1.1.4, SSH protocols 1.5/2.0, OpenSSL 0x0090704f

Java Version:
1.6.0_30

Sample Program:

import com.sshtools.j2ssh.SftpClient;
import com.sshtools.j2ssh.SshClient;
import com.sshtools.j2ssh.authentication.PasswordAuthenticationClient;
import com.sshtools.j2ssh.configuration.ConfigurationLoader;
import java.io.PrintStream;

public class fileTransfer
{
  public static boolean connectToServer(String serverIp, int
serverPort, String userId, String password)
  {
    SshClient sfc = null;
    try {
      System.out.println("inside Try of as its SFTP");
      ConfigurationLoader.initialize(false);
      System.out.println("ConfigurationLoader");

      sfc = new SshClient();
      sfc.connect(serverIp, serverPort);
      System.out.println("sfc.connect");

      PasswordAuthenticationClient pwd = new
PasswordAuthenticationClient();

      pwd.setUsername(userId);

      pwd.setPassword(password);

      int checkAuth = sfc.authenticate(pwd);
      System.out.println("checkAuth " + checkAuth);

      if (checkAuth == 4) {
        System.out.println("AuthenticationProtocolState.COMPLETE");

        SftpClient sftp = sfc.openSftpClient();
        sftp.quit();
        sfc.disconnect();
      }
      else
      {
        throw new Exception("Invalid User Name or Password for user");
      }
    }
    catch (Exception e)
    {
        e.printStackTrace();
      System.out.println("Error While SFTP ");
      sfc.disconnect();
      e.getStackTrace();
      return false;
    }
    return true;
  }

  public static void main(String[] args)
  {
    try
    {
      System.out.println(connectToServer(args[0],
Integer.parseInt(args[1]), args[2], args[3]));
    }
    catch (Exception ex) {
      ex.printStackTrace();
    }
  }
}

Sorry, but we can't help you figure out code we didn't write.
