一、恢复自动分配IP地址 远程vnc桌面终端窗口命令操作，注意引文双引号,出现提示错误，请讲双引号，改成英文双引号！！！

stevenroc@stevenroc:~ $ sudo nmcli connection modify “Wired connection 1” ipv4.method auto ipv4.addresses “” ipv4.gateway “” ipv4.dns “” connection.autoconnect yes

# 核心：sudo提权+改回自动DHCP+清空所有手动固定IP/网关/DNS残留配置  eth0网卡
sudo nmcli connection modify "Wired connection 1" ipv4.method auto ipv4.addresses "" ipv4.gateway "" ipv4.dns "" connection.autoconnect yes
# 立即重启网络连接，配置生效（必须执行） 
sudo nmcli connection up "Wired connection 1"
##显示结果如下
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/7)

# 核心：sudo提权+改回自动DHCP+清空所有手动固定IP/网关/DNS残留配置 eth0网卡
sudo nmcli connection modify "Ethernet connection 1" ipv4.method auto ipv4.addresses "" ipv4.gateway "" ipv4.dns "" connection.autoconnect yes 
# 立即重启网络连接，配置生效（必须执行）  
sudo nmcli connection up "Ethernet connection 1"
##显示结果如下 
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/7)

# 核心：sudo提权+改回自动DHCP+清空所有手动固定IP/网关/DNS残留配置 eth0网卡
sudo nmcli connection modify "chanking" ipv4.method auto ipv4.addresses "" ipv4.gateway "" ipv4.dns "" connection.autoconnect yes
# 立即重启网络连接，配置生效（必须执行） 
sudo nmcli connection up "chanking"
##显示结果如下 
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/7)

二、树莓派5系统设置有线网口一个永久固定IP地址，一个动态IP地址。远程vnc桌面终端窗口命令操作

针对树莓派 5（Raspberry Pi OS Bookworm，默认使用 NetworkManager）的有线网口永久配置固定 IP + 动态 IP，核心是给同一有线连接同时配置 DHCP 动态 IP 和手动固定 IP，且重启后配置不丢失，步骤如下

树莓派5系统设置有线网口一个永久固定IP地址，一个动态IP地址。
# 1. 设为DHCP动态IP模式，开机自动连接
nmcli connection modify "Ethernet connection 1" ipv4.method auto
nmcli connection modify "Ethernet connection 1" connection.autoconnect yes
# 2. 永久添加固定IP（+号表示追加，不覆盖动态IP）
nmcli connection modify "Ethernet connection 1"+ipv4.addresses 192.168.110.15/24
# 3. 重启连接使配置生效
nmcli connection up "Ethernet connection 1"


三、、修改WiFi固定IP地址 远程vnc桌面终端窗口命令操作
1、192.168.110.15修改为192.168.110.35/24
stevenroc@stevenroc:~ $ sudo nmcli connection modify "chanking" ipv4.method manual ipv4.addresses 192.168.110.35/24 ipv4.gateway 192.168.110.1 ipv4.dns "8.8.8.8,114.114.114.114" connection.autoconnect yes

2、
stevenroc@stevenroc:~ $ sudo nmcli connection up "chanking"
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4)

3、192.168.110.17修改为192.168.110.15/24
stevenroc@stevenroc:~ $ sudo nmcli connection modify "chanking" ipv4.method manual ipv4.addresses 192.168.110.15/24 ipv4.gateway 192.168.110.1 ipv4.dns "8.8.8.8,114.114.114.114" connection.autoconnect yes

stevenroc@stevenroc:~ $ sudo nmcli connection up "chanking"
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4)
