ansible报错Incompatible ssh peer (no acceptable kex algorithm)

 在目标服务器上，/etc/ssh/sshd_conf文件最后一行添加下面内容

KexAlgorithms curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1

# 并重启sshd服务，才能生效
# service sshd restart
Stopping sshd: [ OK ]
Starting sshd: [ OK ]

问题描述：运行paromiko连接远程服务器失败：FAIL : SSHException: Incompatible ssh peer (no acceptable kex algorithm)

定位原因：由于ssh 6.7以上屏蔽不安全算法；

解决办法：在/etc/ssh/sshd_config最后加上
