配置无线热点 #

主要用到的软件有hostapd、dnsmasq:

sudo apt-get install hostapd dnsmasq

然后在/etc/dnsmasq.conf末加入(自己修改IP和网段,这个文件是已存在的,很详细的配置文件,但是所有行都加入了#号注释掉)

interface=wlan0
dhcp-range=10.0.0.2,10.0.0.5,255.255.255.0,12h

然后新建/etc/hostapd/hostapd.conf,加入

interface=wlan0
hw_mode=g
channel=10
auth_algs=1
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
rsn_pairwise=CCMP
wpa_passphrase=wifi密码
ssid=wifi名字

接着修改/etc/sysctl.conf,更改(如果有这一行,把#号去掉就行)

net.ipv4.ip_forward=1

最后,将下面脚本加入到/etc/rc.local的exit 0前:

ifconfig wlan0 down
ifconfig wlan0 10.0.0.1 netmask 255.255.255.0 up
iwconfig wlan0 power off
service dnsmasq restart
hostapd -B /etc/hostapd/hostapd.conf & > /dev/null 2>&1
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE  
sudo iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT  
sudo iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT

重启
