永久删除网络接口

Question

我正在尝试永久删除网络接口。出于某种原因，ifconfig列出eth0和eth1，尽管后者的 RX/TX 指标保持为零。

我怀疑额外的eth1条目可能会导致启动期间的延迟。

令人惊讶的是，搜索并没有给出关于如何进行的任何答案。大多数帖子要么针对旧版本的 Ubuntu 或 Debian，要么针对其他发行版 (RedHat)，要么没有永久影响，要么与添加界面有关，或者尝试在启动后将其关闭，或者根本没有得到答复。但答案可能在 Google 的第三个结果页面之后的某个地方。

从桌面上删除第二个条目（顶部栏上的向上和向下箭头）对ifconfig.

编辑：我实际上在 MB 上有两个网卡。我承认这有点令人惊讶。我没有wifi。问题仍然存在，至少是出于好奇。

预先感谢您的帮助。

Answer 1

/etc/network/interfaces在终端中打开文件

sudo nano /etc/network/interfaces

添加这一行：

iface eth1 inet manual

保存文件并运行

sudo service network-manager restart

或者

sudo systemctl restart network-manager.service

要永久删除我认为你应该使用这个

sudo nmcli connection show

结果如下：

NAME                UUID                                  TYPE       DEVICE 
front               2cf067c7-e0ad-4072-b60f-60a7733b5c27  wifi       wlp1s0 
wg0                 ab0b9039-c4b1-48af-b30c-adcbea993643  wireguard  wg0    
WebSolutions        07749022-afa7-467e-a625-a87de9875ab7  vpn        --     
BlackHome           061a7dbf-5d7d-4992-a78d-015b3d93f5af  wifi       --    

然后通过 UUID 删除

sudo nmcli connection delete ab0b9039-c4b1-48af-b30c-adcbea993643
