node.js ssh2 =>如何关闭连接和处理ECONNRESET错误

const Client = require('ssh2').Client;

const conn = new Client();

conn.on('ready', () => {
  console.log('SSH connection established');
  
  // 执行命令或文件传输等操作
  
  // 关闭连接
  conn.end();
});

conn.on('end', () => {
  console.log('SSH connection closed');
});

conn.connect({
  host: 'hostname',
  port: 22,
  username: 'username',
  password: 'password'
});

conn.on('error', (err) => {
  if (err.code === 'ECONNRESET') {
    console.log('Connection reset by peer');
    // 进行错误处理或重连等操作
  } else {
    console.log('Other error:', err);
  }
});
