树莓派3建立WiFi热点

1.使用hostapd+dnsmasq

配置wlan0地址：ifconfig wlan0 192.168.33.1/24

安装软件：apt-get install hostapd,dnsmasq

建立相应配置文件

cat /etc/damask.conf

interface=wlan0

bind-interfaces

server=114.114.114.114

server=8.8.8.8

domain-needed

bogus-priv

dhcp-range=192.168.33.51,192.168.33.70

cat /etc/hostapd/hostapd.conf

interface=wlan0

driver=nl80211

ssid=testap

hw_mode=g

channel=6

ignore_broadcast_ssid=0

wmm_enabled=1

auth_algs=1

wpa=2

wpa_passphrase=12345678

wpa_key_mgmt=WPA-PSK

rsn_pairwise=CCMP TKIP

启动服务

service hostapd start(hostapd -B /etc/hostapd/hostapd.conf)

service dnsmasq start

停止时顺序相反

开启nat转换(可能会先echo 1>/proc/sys/net/ipv4/ip_forward)

iptables -t nat -A POSTROUTING -o eth0 -j MAQUERADE

注：对于systemd开启转发要在如下这里设置

cat /etc/systemd/network/80-dhcp.network

[Match]

[Network]

IPForward=1
