java - JSCH session 连接问题

Question

我运行了下面的程序并重新启动了主机，这需要大约 6 到 8 分钟才能完成重新启动，但我从未超时......也就是说，它永远不会转到其他部分。

    public static void main(String a[]) throws JSchException, InterruptedException {
        java.util.Properties config = new java.util.Properties();
        JSch jsch = new JSch();
        String user = "cli";
        String host = "135.104.217.114";
        String password = "cli";
        int port = 22;
        Session session = jsch.getSession(user,host,port);
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.setPassword(password);
        session.connect();
        while(true)
        {
            if(session.isConnected())
            {
                System.out.println("session connected");
            }
            else
            {
                System.out.println("sesion not connected--------------");
            }
            Thread.sleep(1000);
        }
    }

您很可能需要配置"Sever Alive" properties 。

session.setServerAliveInterval(5000); // Check if server is alive every 5 seconds
session.setServerAliveCountMax(5);  // Disconnect after 5 Server Alive checks did not receive a response.
