Today, when using SSH, connect to a remote server, the beginning is not the problem.
Later, after a bit heavy Tencent cloud host system, no longer Rom. It has reported a fault.
Solution, there is a look at the error log:

To the editor of the way into this file
vim /Users/mengtao/.ssh/known_hosts
The red box portion deleted
Remote connection again, the perfect solution.
The reason is because the only reinstall the system, again on remote connections, after entering yes, this information will be opportunities for the remote machine, writes /Users/mengtao/.ssh/known_hosts file, so if the remote reinstall the system, The machine must first clean out.
