Ubuntu 使用 create_ap 开启 wifi 热点教程

1. create\_ap 获取/安装

git clone https://github.com/oblique/create_ap.git
cd create_ap
sudo make install

2. 获取 wlan/wireless 名字

$ ifconfig

        inet 10.192.86.102  netmask 255.255.252.0  broadcast 10.192.87.255

如某笔记本

• wlan: enp0s31f6
• wireless: wlp5s0

3. 测试create\_ap 是否工作正常

create_ap 基本命令格式:
create_ap wlan0 eth0 MyAccessPoint MyPassPhrase
本机指令
create_ap wlp5s0 enp0s31f6 Thinkpad 20212021

正常就会创建一个名为Thinkpad的 wifi热点， 密码为 20212021

• 常见错误
  如 ERROR: Failed to initialize lock
  需要 rm /tmp/create_ap.all.lock

4. 配置 create\_ap

/etc/create_ap.conf

/etc/create_ap.conf 配置如下项
WIFI_IFACE=wlp1s0 #wireless 网卡名
INTERNET_IFACE=wlp1s0 #wlan 网卡名
SSID=Thinkpad #要建立的热点名称
PASSPHRASE=20212021 #密码

5. 开启关闭命令

sudo systemctl start create_ap # 开启 wifi 热点
sudo systemctl stop create_ap # 关闭 wifi 热点

6. 查看 wifi 热点连接情况

• 查看创建的热点

$ create_ap --list-running
List of running create_ap instances:

329305 wlp5s0 (ap0)
====================================

• 查看连接在 ap 上的设备

create_ap --list-clients 329305    # 该id为之前创建的ap id

MAC                  IP                 Hostname
8c:c8:4b:f0:ac:f7    10.0.0.103         LAPTOP-C9UBHHB6
