修改网卡，网关ip,校园网

本文主要是介绍修改网卡，网关ip,校园网，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、使用校园网的脚本程序：

环境：树莓派，debian10,
修改文件：wpa_supplicant.conf
/etc/wpa_supplicant/目录下的：wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=CNnetwork={ssid="BUPT-mobile"key_mgmt=WPA-EAPpairwise=CCMP TKIPgroup=CCMP TKIPeap=PEAP TTLSscan_ssid=1identity="2019180100"  # 学号password="QWEasd321~"  # 密码phase1="PEAP"phase2="MSCHAPV2"priority=1proactive_key_caching=1
}

之后使用如下命令获取动态ip：

sudo killall wpa_supplicant 
sudo wpa_supplicant -dd -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

另开一个窗口：

ifconfig  #查看网卡wlan0 的ip和子网掩码，然后计算网关

在这里插入图片描述

2、固定wlan0通过wifi获取来的ip

修改文件：/etc/dhcpcd.conf

# Example static IP configuration:
interface eth0
static ip_address=192.168.0.2/24
static ip6_address=fd51:42f8:caae:d92e::ff/64
#static routers=192.168.0.1  # 注释掉这个集群局域网的网关
static domain_name_servers=192.168.0.1 8.8.8.8 fd51:42f8:caae:d92e::1interface wlan0
static ip_address=10.28.210.35/17
static routers=10.28.128.1  # 使用这个网关
static domain_name_servers=10.28.128.1 8.8.8.8

设置树莓派网关绑定的网卡：
eht0 -->wlan0

# Example static IP configuration:
interface eth0
static ip_address=192.168.0.47/24
static ip6_address=fd51:42f8:caae:d92e::ff/64
#static routers=192.168.0.1
static domain_name_servers=192.168.0.1 8.8.8.8 fd51:42f8:caae:d92e::1interface wlan0
static ip_address=10.28.165.172/17
static routers=10.28.128.1
static domain_name_servers=10.28.128.1 8.8.8.810.28.165.172/17  子网掩码：255.255.128.1,165比128大？
