由於我的臺式機連接的路由器，這樣ip是隨機分配的。需要固定ip纔可以遠程方便連接。
若提示未找到 ifconfig 命令則使用如下命令按裝該工具。
bobokaka@bobokaka-desktop:~/桌面$ ifconfig
Command 'ifconfig' not found, but can be installed with:
sudo apt install net-tools
bobokaka@bobokaka-desktop:~/桌面$
安裝該工具。
sudo apt-get install net-tools
查看網卡。
bobokaka@bobokaka-desktop:~/桌面$ ifconfig

可以看到我的網卡信息在enp5s0上面。
安裝vim。
sudo apt-get install vim
修改網卡默認配置文件。
原有配置如下：
Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
改成：
network:
ethernets:
enp5s0:
dhcp4: no
dhcp6: no
addresses:
- 192.168.3.117/24
routes:
- to: default
via: 192.168.3.1
nameservers:
addresses:
- 192.168.3.1
- 8.8.8.8
- 114.114.114.114
version: 2
renderer: networkd
當然，這裏只是參考。
其中
enp5s0是網卡名字
192.168.3.117是ip4的ip地質
子網掩碼是via。
DNS是addresses。
應用該配置。
sudo netplan apply
