解决SSH连接时提示server responded connection closed

这个问题折腾了我大半天，脑子太呆板，搜了一大堆的资料都不管用，其实很简单，卸载重装就完事了，真笨
SSH连接时提示server responded connection closedThe connection to the remote host was lost.This ususlly means that network conneciton has terminated or that the remote host computer was 
rebooted.Most network outages are short,so trying again may help.卸载ssh:sudo apt-get remove openssh-server删除ssh目录：rm -rf /etc/ssh重新创建ssh目录：mkdir /etc/ssh赋予ssh目录读写执行的权限：chmod -R 777 /etc/ssh
