Ubuntu 20.04.1 LTS 網絡配置

netplan配置

# 跳轉至 netplan
$ cd /etc/netplan
$ ls
01-network-manager-all.yaml 
$ cat *.yaml
# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager
# ubuntu 桌面版默認是 NetworkManager 管理網絡連接，這里可以修改成 想要 networkd方式
$ cp 01-network-manager-all.yaml 01-network-manager-all.yaml.backup
# 備份 01-network-manager-all.yaml 
# `注意了 你的網口可能不是這個，查看ifconfig 后再填寫`
$ nano *.yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s4f1:
      addresses:
      - 192.168.16.152/24
      gateway4: 192.168.16.1
      nameservers:
        addresses:
        - 223.5.5.5
        - 223.6.6.6

ubuntu 20 網口名稱 叫 enp3s4f0 和 enp3s4f1，與18不同，這里我配置成 152

你也可以設置成自動配網

network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s4f1:
      dhcp4: true
      dhcp6: true

要更新netplan配置，運行netplan apply命令

sudo netplan apply

WiFi配置

ethernets:
  id0:
    [...]
    access-points:
      mode: infrastructure
      bssid: mywifi
      band: 5GHz
      channel: 5
    auth:
