SSH的 Write failed: Broken pipe 问题,


问题现象:

  

 

 

   表示连接管道已经断开

 

解决方法:  

  方法一:客户端配置
  在客户端的 ~/.ssh/ config文件(如不存在请自行创建)中添加下面内容:
  ServerAliveInterval 60

  方法二:服务器端配置
  在服务器的 /etc/ssh/sshd_config 中添加如下的配置:
  ClientAliveInterval 60

  方法三:临时SSH命令配置
  如果只是临时性的连接(即只作用于当前SSH),可以直接使用 ssh 命令参数进行配置。
  $ ssh -o ServerAliveInterval=60 user@sshserver

//ServerAliveInterval
         Sets a timeout interval in seconds after which if no data has
         been received from the server, ssh(1) will send a message through
         the encrypted channel to request a response from the server.  The
         default is 0, indicating that these messages will not be sent to
         the server.  This option applies to protocol version 2 only.
//ClientAliveInterval
         Sets a timeout interval in seconds after which if no data has
         been received from the client, sshd(8) will send a message
         through the encrypted channel to request a response from the
         client.  The default is 0, indicating that these messages will
         not be sent to the client.  This option applies to protocol
         version 2 only.

  这两个命令前者应用在客户机上,后者应用在服务器上,如果没有管理员权限,那么前者是很好的选择。
  这两个的功能是相同的,都是开启一个发送keep-alive包的功能,这样会允许客户端/服务器在一定时间内发送一个特定的包给对方,一旦超时,则说明断线,就关闭链接。这样就避免了链接长时间挂着导致报错。而且,一旦再次报错,稍等片刻便可以再次登录。
