Question

我想在远程系统上执行命令，并希望获得相同的结果。

我尝试了以下代码：

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();
        }
    }
 }

但是我收到了以下错误：

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 rough.RemoteSSH.main(RemoteSSH.java:23)

任何解决方案。我已经尝试过使用pstool，但没有得到正确的输出。

我的猜测是你没有在目标机器上运行SSH服务器。

请注意，Windows没有任何内置SSH服务器。

确保先安装一些SSH服务器见Is IIS SFTP natively supported by Windows Server 2012 R2?

或使用其他技术运行命令：

使用JSch连接到远程Windows机器
