問題
更新個人博客文章時遇到：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 Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html

解決
用 ssh 命令連接服務器之后，如果一段時間不操作，再次進入時會有一段時間沒有響應，然后就出現錯誤提示：Write failed: Broken pipe
只能重新用 ssh 命令進行連接。
解決方法：
使用以下的命令：$ ssh -o ServerAliveInterval=60 user@sshserver
這里的user是指你的 git 用戶名，sshserver 是指報錯中的 IP。
