git clone 报错 

Unable to negotiate with xxx.xxx.xxx.xxx. port 12345: no matching cipher found. Their offer: aes128-cbc,3des-cbc,blowfish-cbc

解决：

# sudo nano /etc/ssh/ssh_config

 把以下代码放到指定位置，

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc

也就是Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc下面
