APF/OPOS as Wi-Fi Access Point

Page under construction... Informations on this page are not guaranteed !!

Installation

• You will need hostapd (installed by default on APF6):

$ make menuconfig

Target packages  --->
    Networking applications  --->
        [*] hostapd
        [ ]   Enable EAP
        [ ]   Enable WPS

Configuration

• Bring up your Wi-Fi interface and give it an address (here 192.168.2.1):

# ifconfig wlan0 up 192.168.2.1 netmask 255.255.255.0

• Create /etc/hostapd/ directory and put it this hostapd.conf configuration file:

# mkdir -p /etc/hostapd/
# cat > /etc/hostapd/hostapd.conf <<EOF
interface=wlan0
ctrl_interface=/var/run/hostapd
ssid=APF6
hw_mode=g
channel=6
#auth_algs=1
wpa=2
wpa_passphrase=YOUHOULESBILOUS
wpa_key_mgmt=WPA-PSK WPA-PSK-SHA256
EOF

• here we used fixed channel (6) (as some drivers can't allow hostapd to find less occupied channel through scanning)
• security is WPA2-PSK. To have "Open" Access Point uncomment #auth_algs=1 and comment 3 wpa lines

• Launch hostapd:

# hostapd -B /etc/hostapd/hostapd.conf

• If the devices connecting to your Access Point require dynamic IP adress allocation, you will need to install a DHCP server on your APF/OPOS too.
