Question

我正在使用Jsch在我的应用和服务之间创建一个ssh连接，此服务具有必须与连接隧道一起传递的身份验证，因此使用ssh的方式如下：

Session session = jsch.getSession("user_name", "service_url.com", 1443);
Properties config = new Properties();

config.put("kex", "diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1");
//config.put("kex", "diffie-hellman-group-exchange-sha256"); //tried this individually also 
//config.put("kex", "diffie-hellman-group1-sha1"); //tried this individually also
config.put("StrictHostKeyChecking", "no");

session.setConfig(config);
session.setPassword("abc123");
try{
    session.connect(5000); // Exception raises here
}catch(JSchException hs){
    hs.printStackTrace(); // Exception caught here
}

但是在到达session.connect()时，即使在等待5000 ms方法中提到的connect()之前，我也会遇到以下异常：

com.jcraft.jsch.JSchException: Session.connect: java.io.IOException: End of IO Stream Read
    at com.jcraft.jsch.Session.connect(Session.java:558)
    at com.example.updaterjschtest.MainActivity$1$1.run(MainActivity.java:132)
    at java.lang.Thread.run(Thread.java:818)

值得一提的是，我遇到this question和this question，但答案没有帮助。

使用putty：
