我正在尝试通过 ssh 连接到我无法控制的 CentOS 服务器。
.ssh 中的配置：
tim@tim-UX31A:~$ cat ~/.ssh/config
User root
PasswordAuthentication no
IdentityFile ~/.ssh/id_rsa
我的密钥文件的权限：
tim@tim-UX31A:~$ ls -l ~/.ssh/id_rsa*
-rw------- 1 tim tim 3326 Okt 20 17:28 /home/tim/.ssh/id_rsa
-rw-r--r-- 1 tim tim 746 Okt 20 17:28 /home/tim/.ssh/id_rsa.pub
我无法理解的连接日志：
tim@tim-UX31A:~$ ssh -vvv root@10.0.12.28
OpenSSH_7.2p2 Ubuntu-4ubuntu2.1, OpenSSL 1.0.2g 1 Mar 2016
