当我 ssh 进入一台新机器时，我遇到了这个奇怪的问题，但我的known_hosts 文件会使用某种哈希值进行更新，但不会更新主机名。当我稍后尝试通过 SSH 连接到同一台机器时，这最终导致我无法自动完成。
例如：
我的known_hosts 文件的最后两行：
10.1.x.xx ecdsa-sha2-nistp256 AAAAE2VjZHNhLXN ... the rest of the hash
db03.test.fqdn.com ecdsa-sha2-nistp256 AAAAE2 ... the rest of the hash
我通过 SSH 连接到盒子：
#ssh app01.test.fqdn.com
[~]$ ssh app01.test.fqdn.com
The authenticity of host 'app01.test.fqdn.com (10.1.2.92)' can't be established.
ECDSA key fingerprint is SHA256:2zbk+M6WbAwjBbtODTklKDqctO/b2JQgirf4LWGh3jE.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'app01.test.fqdn.nl,10.1.x.xx' (ECDSA) to the list of known hosts.
