• ssh连接报错server responded”algorithm negotiation failed”


    ssh工具版本太低,OpenSSL版本升的比较高,有些算法不支持。

    解决方法:

    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,umac-64@openssh.com,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,curve25519-sha256@libssh.org

    重启sshd服务后,即可正常连接:

    service ssh restart

    2、建议升级ssh客户端版本
