 要么是MACs，要么是KexAlgorithms

1.MACs 解决方法：
修改ssh配置文件 /etc/ssh/sshd_config
在MACs 后面添加hmac-sha1-96 如下：

MACs hmac-sha2-256,hmac-sha1-96

2.KexAlgorithms解决办法：替换KexAlgorithms的值

KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group1-sha1,[email protected]
