比较早期的单盘 MyBooklive。前几天忽然 Web 和媒体服务不可用，smb 和 afp 也连不上，只剩 ssh 可用：
$ ssh [email protected] 'reboot'
[email protected]'s password:
...
$ ssh [email protected] 'cat /etc/version'
[email protected]'s password:
02.43.10-048
$ curl http://192.168.4.56:80
curl: (7) Failed to connect to 192.168.4.56 port 80: Connection refused
$ curl http://192.168.4.56:9000
curl: (7) Failed to connect to 192.168.4.56 port 9000: Connection refused
ssh 登录设备查看，发现这些服务都没有启动。
