OpenSSH in Linux解决方法

方案一：ssh -o选项指定KexAlgorithms和HostKeyAlgorithms

ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 -o HostKeyAlgorithms=+ssh-rsa user1@192.168.1X.XX

注：  -o \’option\’ Process the option as if it was read from a configuration file.

方案二：配置/etc/ssh/ssh_config客户端配置文件

KexAlgorithms=+diffie-hellman-group1-sha1
HostKeyAlgorithms=+ssh-rsa
MACs=+hmac-sha1
