这两种方法并不等同，我认为你的解释是错误的。
您从本地计算机连接到，然后再连接到（通过在 上运行）。第二个连接使用用户可用的凭据和配置（您的本地配置与此连接无关）。两个连接都成功。ssh … [email protected] ssh [email protected]192.168.56.11192.168.56.1110.0.3.120ssh [email protected]192.168.56.11jump192.168.56.11
从本地计算机连接到然后ssh … -J [email protected] [email protected]192.168.56.11从您的本地计算机到10.0.3.120，使用通过 转发的数据包192.168.56.11。第二个连接使用本地用户可用的凭据和配置。跳转主机上的配置和密钥无关，ssh跳转主机上没有运行任何进程。每个连接都在您的本地计算机中启动并涉及您的本地配置。这是第二次连接失败。
192.168.56.11在每种情况下，从本地计算机的连接都有效。我没有看到任何证据表明您的自定义配置被忽略。区别在于后来发生的事情。
看起来：
（没有
-J）[email protected]能够[email protected]使用其配置和凭据登录；（带有
-J）您的本地帐户无法[email protected]使用本地配置和本地凭据。
这就是区别。
您发布的配置文件（它是本地配置，对吧？）包含 的条目192.168.56.11，但没有 的条目10.0.3.120。如果您想在从本地连接时使用相同的身份文件，10.0.3.120那么您需要添加
Host 10.0.3.120
IdentityFile id_ed25519-client_test
到本地配置。
旁注（参见man 5 ssh_config）：对于每个参数，将使用第一个获得的值。因此，您通常应该将特定于主机的声明放置在文件开头附近，并将一般默认值放置在文件末尾。你Host *以前有过Host 192.168.56.11。目前的配置没有问题然而，但是通过进一步自定义配置，您可能会遇到以下情况：下面的某些行Host *与下面的某些行发生冲突Host 192.168.56.11，那么下面的行将Host *“获胜”（例子）。考虑将该Host *部分移至末尾。
