如何通过以太网将嵌入式 Linux 系统连接到 PC？

我有一块带有 Linux 系统的定制主板，我想通过 ssh 将它连接到通过以太网运行 ubuntu 的个人电脑。

在 Windows 上，我使用 Putty 连接开发板，但在 Linux 上我甚至不知道如何启动。我如何查看开发板是否已连接到 PC？我需要一些驱动程序，因为我使用的是 USB 转以太网电缆？一般来说，我应该如何连接开发板并使用 ssh 访问它？

谢谢您，如果问题太笼统，请见谅。

另外，我认为 USB 以太网适配器不能被识别为 ETH 连接，这是输出：

要查找哪些计算机连接到了您的网络，您必须登录路由器。它会显示所有已连接设备的列表以及每个连接的 IP。大多数路由器允许您通过 Web 浏览器登录。

然后，您可以在个人电脑上安装 Remmina（或类似的东西）来连接到网络上的另一台计算机，例如您在问题中提到的客户板。
