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