晚上好🌙🌙🌙
本答案参考ChatGPT-3.5

要解决这个问题，您可以尝试以下步骤：

1. 检查您的~/.ssh/known_hosts文件中是否有错误的或不正确的证书信息。如果您确定您的服务器上有正确且完整的证书，则需要删除不需要的证书。

   可以使用ssh-keygen命令来生成一个新的公钥和私钥对，并将它们添加到known_hosts文件中：

   ssh-keygen -t rsa -b 4096 -C "[e-mail]" -q
   

2. 如果您想确保所有必要的更改都已成功执行，并使系统能够通过SSH连接到远程服务器，可以运行以下命令检查您的SSH配置是否正常工作：

   ssh-keyscan 192.168.1.28 | grep server
   

   如果运行结果为server，则说明安装和配置过程已经完成。

   确保server是你想要连接到的远程服务器的IP地址。

3. 如果问题仍然存在，可能是因为Windows系统中无法连接到Linux发行版的远程服务器。在这种情况下，您可能需要手动安装SSH服务。为此，请按照以下步骤操作：

   a. 打开命令提示符，然后输入以下命令安装SSH服务：

   netsh advfirewall firewall add rule name=" Allow remote access" dir=in action=allow protocol=tcp localport=22 comma-separated-list=<target-ip-or-port>
   

   其中 <target-ip-or-port> 是您想要允许的远程主机的IP地址或端口号。

   b. 接下来，打开~/.ssh/config文件，找到 Host <hostname> 的行，并将其替换为 Allow remote access 行中的目标 IP 地址或端口号。例如：

   Host <hostname>
       HostName <target-ip-or-port>
       Port 22
       IdentityFile ~/.ssh/id_rsa_server
   

   c. 最后，保存并关闭文件。

4. 后续，您可以通过命令行输入 ssh 命令来连接到远程服务器。

注意：这种方法可能不会立即解决问题，因为它涉及到重置某些配置项。因此，在执行此操作之前，建议先备份重要数据。
