解决 SSH Connection closed by foreign host 问题

用 Xshell 连接服务器总是报错 :

Connection closed by foreign host.
Disconnected from remote host...

原因可能是 SSH 服务器没设置保活时间间隔 , 具体设置如下 :

操作

# vim /etc/ssh/sshd_config

添加两行 , 或去掉注释 :

ClientAliveInterval 60
ClientAliveCountMax 3

重启 SSH 服务 :

/etc/init.d/ssh restart
systemctl restart sshd //这个命令我没执行成功，最后还是远程连接上了

补充

ClientAliveInterval 参数数值是秒 , 是指超时时间 , 上面设置的是一分钟 ;
ClientAliveCountMax 设置允许超时的次数 , 上面设置的是允许三次 , 之后就关闭连接 ;
