我有一台旧笔记本电脑,用来学习 Ubuntu Server 12.10。在重新格式化和安装 Ubuntu Server 之前,使用的是 Ubuntu Desktop。
使用 Ubuntu 桌面,我使用 no-ip.com 托管域通过 ssh 访问机器(没问题)。重新格式化后,我尝试使用相同的 no-ip.com 域访问同一台机器(家庭局域网上的相同静态 ip),但现在我收到以下错误:
WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX: (Omitted).
Please contact your system administrator.
