在 android 中通过 ssh 连接到路由器

Question

你好，我想写一个程序，通过 Ssh 协议将 phone 连接到路由器，并使用 jsch 库。

但是连接的时候出现这个错误

我检查了与 this and this 相同的问题，但其中 none 解决了我的问题。

I added to the manifist Internet access.

Through the putty, I can connect to this router so there is no problem on the router.

有人可以帮忙吗？

主要Class :

connect.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            new AsyncTask<Integer, Void, Void>(){
                @Override
                protected Void doInBackground(Integer... params) {
                    try {
                        SSHManager ssh=new SSHManager("amir","123","192.168.66.120");
                        ssh.execute();
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                    return null;
                }
            }.execute(1);

        }
    });

SSHManager Class :

public class SSHManager {
    private JSch jsch;
    private String hostname = null;
    private String username;
    private String password;
    private Session session;
    private ChannelExec channel;
    private int connectioPort = 22;
    private void SSHManager (String userName,
                                            String password, String connectionIP) {
        this.username = userName;
        this.password = password;
        this.hostname = connectionIP;
    }
    public String execute() {

        try {
            jsch = new JSch();
            session = jsch.getSession(username, hostname, 22);
            session.setPassword(password);
            session.setConfig("StrictHostKeyChecking", "no");
            session.setTimeout(10000);
            session.connect();
            channel = (ChannelExec) session.openChannel("exec");
            channel.setCommand("en\n123\nconf t\nexit");
            channel.connect();
            channel.disconnect();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;

    }
}

Answer 1

试试这个：

jsch = new JSch();
session = jsch.getSession(UserName, HostName, PortNumber);
session.setPassword(PassWord);
Properties prop = new Properties();
prop.put("StrictHostKeyChecking", "no");
session.setConfig(prop);
session.connect();
channel = (Channel) session.openChannel("shell");
channel.connect();
channel.disconnect();

更新：

有时您应该设置一个属性值，然后将其添加到您的会话中。
