我正在尝试让 Amanda 使用 SSH 身份验证。在我将其安装在服务器上并使用硬盘作为磁带进行基本配置后，我就可以启动并运行它，尽管没有客户端支持。但至少我在本地计算机上获得了备份。
然后我想让它与 SSH 和 ssh-keys 一起工作。有一件事让我很烦恼，那就是我的本地备份不再起作用了：
backup@backup-test:~$ amcheck DailySet1

是的，我知道我有两个本地主机地址，但我也想确保这不是名称错误。
如上所示，另一部分是远程客户端上的 EOF 错误。所有内容都在同一个网络中，并且所有 VM 都位于同一个主机服务器上。对于我使用的用户，SSH 是双向工作的。而且我还看到了所有权限。以下是我的 amcheck 日志的示例：

在阅读了有关此问题的指南和论坛后，我仍一无所获。希望这里有人能提供一些线索。

那么，问题是否出在服务器本身缺少 ssh 密钥？如果您遇到的是这个问题，请将其标记为已解决，以便其他人可以从您的经验中受益。
