1.下載cygwin，並安裝Net類別下的OpenSSH和OpenSSL；
設置環境變量，把 C:/cygwin/bin;C:/cygwin/usr/bin 加入到系統環境變量的Path中；
2.管理員身份打開cygwin，輸入
$ ssh-host-configShould StrictModes be used?

Should privilege separation be used? (yes/no) 選擇：no,
Copying skeleton files.
These files are for the users to personalise their cygwin experience.
They will never be overwritten nor automatically updated.
