ssh連接報錯server responded”algorithm negotiation failed”

com cast conf cipher config ecdh 支持 r12 led

ssh工具版本太低,OpenSSL版本升的比較高,有些算法不支持。

解決方法:

1、修改ssh的配置文件 /etc/ssh/sshd_config

cd /etc/ssh
vi /etc/ssh/sshd_config

在配置文件中添加:

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-sha1-96,hmac-md5-96

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]

重啟sshd服務後,即可正常連接:

service ssh restart

2、建議升級ssh客戶端版本
