Connect to a remote Windows machine using JSch

Question

I want to execute a command on a remote system and want to get the result from it.

I tried the following code:

package rough;
import java.io.InputStream;
import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelExec;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

public class RemoteSSH {

    public static void main(String[] args) {
        String host = "\\\\10.209.110.114";
        String user = "Administrator";
        String password = "Admin123";
        String command1 = "ipconfig";
        try {
            java.util.Properties config = new java.util.Properties();
            config.put("StrictHostKeyChecking", "no");
            JSch jsch = new JSch();
            Session session = jsch.getSession(user, host, 22);
            session.setPassword(password);
            session.setConfig(config);
            session.connect();
            System.out.println("Connected");

            Channel channel = session.openChannel("exec");
            ((ChannelExec) channel).setCommand(command1);
            channel.setInputStream(null);
            ((ChannelExec) channel).setErrStream(System.err);

            InputStream in = channel.getInputStream();
            channel.connect();
            byte[] tmp = new byte[1024];
            while (true) {
                while (in.available() > 0) {
                    int i = in.read(tmp, 0, 1024);
                    if (i < 0)
                        break;
                    System.out.print(new String(tmp, 0, i));
                }
                if (channel.isClosed()) {
                        System.out.println("exit-status: " + channel.getExitStatus());
                    break;
                }
                try {
                    Thread.sleep(1000);
                } catch (Exception ee) {
                }
            }
            channel.disconnect();
            session.disconnect();
            System.out.println("DONE");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
 }

But I get the following error:

com.jcraft.jsch.JSchException: java.lang.IllegalArgumentException: protocol = socket host = null
    at com.jcraft.jsch.Util.createSocket(Util.java:258)
    at com.jcraft.jsch.Session.connect(Session.java:186)
    at com.jcraft.jsch.Session.connect(Session.java:145)
    at rough.RemoteSSH.main(RemoteSSH.java:23)
Caused by: java.lang.IllegalArgumentException: protocol = socket host = null

    ... 3 more

any solution for him. I already tried using pstool but did not get the correct output.

Answer 1

My wild guess is that there is no SSH server on the target machine.

Please note that Windows does not have an integrated SSH server.

Make sure you install the SSH server first.

Or use another technology to run the command:
