Debian开WI-FI热点

操作系统：Debian Gnu/Linux 8.3
内核： linux-image-4.3.0-0.bpo.1-amd64
网卡：腾达(Tenda) W311M 150M Mini无线USB网卡

执行vi /etc/apt/sources.list,并添加如下源地址：

deb http://ftp.cn.debian.org/debian/ jessie-backports main contrib non-free

安装最新内核及相关软件组件包，避免编译Hostapd出错，依次执行如下命令：

apt-get update
apt-get install linux-image-4.3.0-0.bpo.1-amd64
apt-get install linux-headers-4.3.0-0.bpo.1-all-amd64 
apt-get install pkg-config
apt-get install libssl-dev 
apt-get install gettext
apt-get install openssl
apt-get install libnl-genl-3-dev
apt-get install libnl-genl-3-200
apt-get install libnl-3-dev
apt-get install libnl-3-200
apt-get install hostapd

进入http://w1.fi/hostapd/网站下载hostapd-2.5.tar.gz文件

wget http://w1.fi/releases/hostapd-2.5.tar.gz

解压并复制配置文件

tar -zxvf hostapd-2.5.tar.gz
cd hostapd-2.5
cp defconfig .config

使用vi .config命令对该文件进行修改，修改内容如下：

# Use libnl v2.0 (or 3.0) libraries.
CONFIG_LIBNL20=y
# Use libnl 3.2 libraries (if this is selected, CONFIG_LIBNL20 is ignored)
CONFIG_LIBNL32=y
# IEEE 802.11n (High Throughput) support
CONFIG_IEEE80211N=y

保存退出，编译安装：

make
make install

系统将在/usr/local/bin目录下生成两个文件名为hostapd、hostapd_cli的可执行文件。

将hostapd配置文件复制到/etc/hostapd/文件夹下，并将相关字段修改为如下内容：

cp hostapd.conf /etc/hostapd/
vi  /etc/hostapd/hostapd.conf
interface=wlan1
driver=nl80211
ssid=LONUXPROBE
hw_mode=g
channel=7
macaddr_acl=0
auth_algs=3
ignore_broadcast_ssid=0
wmm_enabled=1
ieee80211n=1
ht_capab=[HT40-][SHORT-GI-20][SHORT-GI-40]
wpa=2
wpa_passphrase=linuxprobe
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP 

使用vi对该文件进行编辑，修改内容如下：

vi /etc/default/hostapd
DAEMON_CONF="/etc/hostapd/hostapd.conf"

对hostapd服务脚本进行编辑，修改内容如下：

vi /etc/init.d/hostapd
DAEMON_SBIN=/usr/local/bin/hostapd

并在start)下一行添加如下内容：

sed -i '//[keyfile/]/a unmanaged-devices=mac:c8:3a:35:cb:18:e0' /etc/NetworkManager/NetworkManager.conf
        ip addr add 192.168.11.1/24 dev wlan1
        echo "1" >/proc/sys/net/ipv4/ip_forward
        iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
        sleep 2

在stop)下一行添加如下内容：

sed -i '/^unmanaged-devices=mac:c8:3a:35:cb:18:e0/d' /etc/NetworkManager/NetworkManager.conf
        echo "0" >/proc/sys/net/ipv4/ip_forward
        ip addr del 192.168.11.1/24 dev wlan1
        iptables -t nat -D POSTROUTING -o wlan0 -j MASQUERADE
        sleep 2

在reload)下一行添加如下内容：

        sed -i '/^unmanaged-devices=mac:c8:3a:35:cb:18:e0/d' /etc/NetworkManager/NetworkManager.conf
        echo "0" >/proc/sys/net/ipv4/ip_forward
        ip addr del 192.168.11.1/24 dev wlan1
        iptables -t nat -D POSTROUTING -o wlan0 -j MASQUERADE
        sed -i '//[keyfile/]/a unmanaged-devices=mac:c8:3a:35:cb:18:e0' /etc/NetworkManager/NetworkManager.conf
        ip addr add 192.168.11.1/24 dev wlan1
        echo "1" >/proc/sys/net/ipv4/ip_forward
        iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
        sleep 2

保存退出，(根据自己情况设定参数mac和ip)对脚本文件进行重新配置：

systemctl daemon-reload

apt-get install dnsmasq

vi /etc/dnsmasq.conf
resolv-file=/etc/resolv.dnsmasq.conf
server=/cn/114.114.114.114
server=/taobao.com/114.114.114.114
server=/google.com/8.8.8.8
listen-address=127.0.0.1,192.168.11.1
dhcp-range=192.168.11.50,192.168.11.150,12h
dhcp-option=3,192.168.11.1
dhcp-option=6,192.168.11.1
cache-size=1024
conf-dir=/etc/dnsmasq.d

vi /etc/resolv.dnsmasq.conf
nameserver 114.114.114.114
nameserver 223.5.5.5
nameserver 223.6.6.6

vi /etc/resolv.conf
nameserver 127.0.0.1

分别使用命令：

systemctl enable dnsmasq.service
systemctl disable hostapd.service

开启和关闭两项服务，之后在需要使用热点模式时使用命令：

systemctl start hostpad.serive

用户即可使用热点名为LINUXPROBE,密码为linuxprobe,网关地址和DNS均为192.168.11.1的80211N协议无限热点进行上网连接啦！
