ccs的杜甫，用着用着22端口突然全球红
发工单查了半天给我来了句：
It looks like the networking for this machine was not set up properly during install.
You would have to login via IPMI to edit your networking files or reintall the machine.
We can troubleshoot further, but that would be considered billable.
部署的其他端口的服务都是正常运行的，就是22端口全球红了连不上机器，有大佬知道咋回事吗？不想重装系统啊，部署了好久啊没备份的
