问题

更新个人博客文章时遇到：Error: packet_write_wait: Connection to 192.30.253.113 port 22: Broken pipe

  packet_write_wait: Connection to 192.30.253.113 port 22: Broken pipe
  fatal: sha1 file '<stdout>' write error: Broken pipe
  fatal: The remote end hung up unexpectedly
  fatal: The remote end hung up unexpectedly
  FATAL Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html

解决

  用 ssh 命令连接服务器之后，如果一段时间不操作，再次进入时会有一段时间没有响应，然后就出现错误提示：Write failed: Broken pipe

只能重新用 ssh 命令进行连接。

  解决方法：

  使用以下的命令：$ ssh -o ServerAliveInterval=60 user@sshserver

  这里的user是指你的 git 用户名，sshserver 是指报错中的 IP。
