无法使用静态 IP 地址通过直接光纤连接从 Win10 到 Ubuntu 20.04 进行 ping 操作

到目前为止，我的电脑还不能直接连接到我的服务器，我希望有人能知道我哪里出错了或者我错过了什么。我搜索了很多帖子，花了一些时间尝试了我所知道的一切。 Windows 显示适配器已连接

ubuntu 显示适配器已关闭，直到我在 ubuntu 上运行“ip link set enp4s0 up”，我遇到此问题的 10gbe 适配器是 enp4s0

我有 2 台机器，每台都连接了 2 个网卡。

一个 Gbe 适配器连接到更宽的局域网 192.168.0.0，一个 10gb spf+ Mellanox connectx-3 直接连接 192.168.2.0 网络上的机器。两台机器都有匹配的 Mellanox 卡和收发器

我正在使用这些收发器 FS for Mellanox MFM1T02A-SR 兼容 10GBASE-SR SFP+

@Preston Maness 这个想法不错，但是我依然无法成功 ping 通。

（enps4s0应该enp4s0。）

我还怀疑您需要在 Windows 端添加路线。

总之，对于直接连接的主机之间建立连接：

  1. 确保两个主机的 IP 地址位于同一子网中，并与直接连接（“在线”）的接口相关联。
  2. 确保两个主机都有路由，指示到该子网的流量直接从接口推出（“在链路上”），而不是转发到网关。
