用XSHELL鏈接linux服務器出現如下錯誤

Connecting to 42.51.xxx.xxx:22...

Connection established.

To escape to local shell, press 'Ctrl+Alt+]'.

Socket error Event: 32 Error: 10053.

Connection closing...Socket close.

Connection closed by foreign host.

Disconnected from remote host(42.51.xxx.xxx:22) at 20:00:30.

Type `help' to learn how to use Xshell prompt.

操做：用SSH工具鏈接linux電腦出現的問題：Read from socket failed: Connection reset by peer

原由：改變了系統權限 chmod 777 -R 

解決辦法：#chmod 400 /etc/ssh/*

從新鏈接 成功！！！

重啓SSH

service sshd restart

注意：修改# chmod 770 /etc/ssh/ssh_host_dsa_key.pub

          # chmod 770 /etc/ssh/ssh_host_rsa_key.pub

重啓網關

service network restart

忠告：linux系統文件的權限請勿亂改。
