Ubuntu

啟動/啟動我的 ubuntu 時出現許多橋接網路

  • October 14, 2019

當我啟動 ubuntu 18.04 時，我的 ifconfig 中有許多橋接網路。在刪除其中一些網路之前，我無法連接某些網路（既不是有線也不是 wifi）。

刪除它們後，系統可以正常工作。

/etc/network/interfaces 的內容：

# interfaces(5) file used by ifup(8) and ifdown(8)
lo
iface lo inet loopback

如果配置：

他們有關係嗎？我是開發人員，而不是網路專業人士。

期望狀態：

$$ EDIT $$ 所以這些網路似乎是 docker 網路。我正在嘗試刪除，因此其中一個似乎與網路中的某些內容重疊，我遇到了問題。正在努力…

期望狀態：

WIFI 或 LAN 工作。刪除未使用的橋接網路。

$$ EDIT $$ /etc/netplan/01-network-manager-all.yaml

# Let NetworkManager manage all devices on this system
network:
 version: 2
 renderer: NetworkManager

你肯定在執行 Docker。這可以通過一些資訊來推斷：

  • 網橋名稱看起來像 Docker 網橋
  • 具有 IP 集的網橋使用經典的 Docker 網橋 IP：/16在172.16.0.0/12空間中
  • 你是開發者
  • 每個網橋 MAC 地址都以 開頭02:42，它指定一個私有 MAC（很好），但如果它們真的是隨機的，它們會有很多其他的可能性。這篇與 Docker 相關的 SO 文章談到了它：Docker 如何為容器分配 MAC 地址？. 那裡的官方連結已經不存在了。
  • 在 Docker 文件站點上執行搜尋：https ://docs.docker.com/search/?q=02%3A42顯示了很多具有這種 MAC 特性的範例，它不可能是別的東西（遺憾的是我沒有找到關於 MAC 地址的原始連結）。

通過所有這些線索，我可以相當安全地假設您的問題是由執行多個 Docker 網路引起的，這些網路與您通常的網路路由發生干擾。只需更改他們的設置以不再乾擾。這可能應該作為一個單獨的問題來完成（我不知道 SO 或這裡是否最適合）。這應該與docker network它的子命令有關。
