建立一個可程式的無線網路擷取點

Raspberry Pi 3 model B 已經內建 Wifi, 因此只要安裝

hostapd – Host AccessPoint Daemon

wpa-supplicant – tool responsible for WPA authorization

isc-dhcp-server

ip-tables - router

sudo apt-get update sudo apt-get -y install hostapd isc-dhcp-server iptables wpa_supplicant

/etc/hostapd/hostapd.conf

/etc/dhcp/dhcpd.conf

/etc/network/interfaces

auto wlan0 allow-hotplug wlan0 iface wlan0 inet static address 192.134.3.1 netmask 255.255.255.0 up iptables-restore < /etc/iptables.ipv4.nat

Let’s turn on packet forwarding in /etc/sysctl.conf by making sure that line

net.ipv4.ip_forward=1

wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

sudo apt-get -y install bridge-utils

auto lo

iface lo inet loopback iface eth0 inet dhcp

auto br0 iface br0 inet dhcp bridge_ports eth0 wlan0
