连接linux主机A失败，返回
i Available Remote Kex Methods = curve25519-sha256,curve25519-sha256@libssh.org,... i Selected Kex Method = |
连接linux主机B成功，返回
i Available Remote Kex Methods = curve25519-sha256@libssh.org,ecdh-sha2-nistp256,... i Selected Kex Method = diffie-hellman-group14-sha1 |
原因是主机A中的OpenSSH升级了，可用以下命令确认
1 | ssh -V |
解决办法为，在/etc/ssh/sshd_config文件尾部加入
1 2 3 | #Ciphers aes128-cbc #MACs hmac-md5,hmac-sha1 KexAlgorithms diffie-hellman-group14-sha1 |
重启sshd
1 | service sshd restart |
