我一直在使用enp7s0（以太网）和wlp5s0（wifi），但还有一些我不认识的其他网络接口在 dmesg 中定期显示。它们是什么？如何删除它们？
$ sudo dmesg -w

我怎么知道是哪个软件创建了这些？
答案1
您的列表如下所示：
- lo=环回
- enp7s0 = 以太网
- lp5s0 = 无线局域网
- virbr* = 虚拟网桥
- lxcbr* = lxc/lxd
- 码头工人* = 码头工人
- br* = 码头桥
- veth* = 虚拟以太网设备
你可以使用纳米克利（网络管理员）
并运行：
$ nmcli device list
为您泊坞窗容器运行：
$ docker network ls
比
$ docker network inspect [USE THE NETWORK ID FROM THE FIRST COMMAND]
尝试以下方法获取网络设备列表：
$ echo /sys/class/net/*
您可以通过以下方式获取更多信息乌德瓦德姆：
$ udevadm info -a -p /sys/class/net/[NETWORK DEVICE NAME]
例子：
$ udevadm info -a -p /sys/class/net/enp0s25
和ip：
$ ip -r link
$ ip -br link
$ ip -br -c link show
$ ip token
$ ip -s -s link show dev docker0
和长沙：
$ lshw -class network
$ lshw -class network -short
