nic：發生了一些邪惡的事情！ffff

  • January 26, 2019

我正在使用 Debian Stretch (9.7) 配置 GNU/Linux 路由器，在重新啟動伺服器之前，從一個介面到另一個介面的所有流量都正常，但在那之後，我收到了這樣的消息 (tty)：

enp1s6: Something Wicked happened! ffff.

出於測試目的，我在同一交換機和同一網路上有一台主機，基本上，路由器的 LAN 沒有響應回應要求。

這裡有一些關於伺服器的資訊。

有什麼猜測嗎？

請耐心等待：我是前系統管理員（多年以來），現在是軟體開發人員。

看來您的 Sundance 10/100 NIC 很舊，也許太舊了…

請參閱https://bugzilla.redhat.com/show_bug.cgi?id=748973（插入千兆路由器時 f16 Sundance 10/100 乙太網模組崩潰）

根據您的 ethtool 輸出，我注意到 enp1s6 沒有報告為支持自動協商。您正在連接的設備/埠上是否也禁用了該功能？如果可能，請調整您要連接的設備以啟用自動協商。如果您無權訪問該設備，或者您不想更改它，那麼您可能必須在 enp1s6 上強制使用 speed/duplix。
