## 实例
### 远程登录 / 执行 cmd
```
ce := func(err error, msg string) {
if err != nil {
log.Fatalf("%s error: %v", msg, err)
}
}
client, err := ssh.Dial("tcp", "192.168.0.151:22", &ssh.ClientConfig{

session, err := client.NewSession()
ce(err, "new session")
defer session.Close()
session.Stdout = os.Stdout
session.Stderr = os.Stderr
session.Stdin = os.Stdin
// 方式一: ssh 直接执行
//session.Run("ls -l")
// 方式二:在控制台控制
