提示错误:server responded "algorithm negotiation failed”

解决办法:

修改ssh的配置文件 /etc/ssh/sshd_config文件

在末尾加上如下代码:

Ciphers aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-cbc,arcfour128,arcfour256,arcfour,blowfish-cbc,cast128-cbc
MACs hmac-md5,hmac-sha1,[email protected],hmac-ripemd160,hmac-sha1-,hmac-md5-
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]

此外,为保障ssh正常连接,还需要再次修改该配置文件

将配置文件中的”PermitRootLogin without-password“加一个”#”注释掉,然后再增加一句”PermitRootLogin yes

重启sshd服务后,即可正常连接。

sudo service ssh restart
