Access Point
1. Install the following
sudo apt-get install hostapd isc-dhcp-server iptables wpasupplicant
2. Configure AP Daemon
sudo nano /etc/hostapd/hostapd.conf -- interface=wlan0 #wlan0 will be working in AP mode ssid=Your_AP_SSID #your AP SSID channel=1 #WiFi channel used by AP # WPA and WPA2 configuration macaddr_acl=0 #indicates that you do not use MAC address allow/deny list auth_algs=1 #indicates algorithm specified by IEEE 802.11 ignore_broadcast_ssid=0 #AP will broadcast SSID #WPA settings wpa=2 #WPA algorithm used (WPA2 in this case) wpa_passphrase=my_secret_pass #AP password wpa_key_mgmt=WPA-PSK #WPA key mangement type wpa_pairwise=TKIP #encription algorithm rsn_pairwise=CCMP #encription algorithm #Hardware configuration driver=rtl871xdrv #type of driver to be used (in may be different depending on your WiFi dongle chipset) #in majority of cases it will be driver=nl80211 <-- use this for Buffalo Wifi USB dongle ieee80211n=1 #Whether IEEE 802.11n (HT) is enabled hw_mode=g #WPS RF Bands (a = 5G, b = 2.4G, g = 2.4G, ag = dual band) ##Note : for Buffalo Wifi USB dongle (Ralink RT8070) #country_code=JP #channel=2 #beacon_int=100 #max_num_sta=5
3. set up /etc/hostapd/hostapd.conf as the configuration file
sudo nano /etc/default/hostapd DAEMON_CONF="/etc/hostapd/hostapd.conf"
4. configure the network settings for clients connecting to AP
sudo nano /etc/dhcp/dhcpd.conf --- ddns-update-style none; #DDNS disabled default-lease-time 600; #IP lease time max-lease-time 7200; authoritative subnet 192.168.10.0 netmask 255.255.255.0 { #AP Subnet definition range 192.168.10.10 192.168.10.20 ; #Range of IP addresses available for clients option broadcast-address 192.168.10.255; option routers 192.168.10.1; #your client's gateway / router IP option domain-name "local-network"; #optional domain name option domain-name-servers 8.8.8.8, 8.8.4.4; #your DNS IP }
5. set up DHCP server configuration file
sudo nano /etc/default/isc-dhcp-server DHCPD_CONF="/etc/dhcp/dhcpd.conf" INTERFACES="wlan0"
6. configure wlan0 for static IP adress (the same as router IP in dhcpd.conf file)
sudo nano /etc/network/interfaces ---- auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet static address 192.168.10.1 netmask 255.255.255.0 up iptables-restore < /etc/iptables.ipv4.nat
7. setting up Network Address Translation (NAT). Turn on packet forwarding in /etc/sysctl.conf
sudo nano /etc/sysctl.conf ---- net.ipv4.ip_forward=1
8. start the translation right away by running:
sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"
9. setting up the actual translation between the ethernet port called eth0 and the wireless card called wlan0
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
10. save the setting
sh -c "iptables-save > /etc/iptables.ipv4.nat"
11. In order to start AP on boot run the following commands:
sudo update-rc.d hostapd enable sudo update-rc.d isc-dhcp-server enable
12. When you got trouble with the dhcp server, restarting both hostapd and isc-dhcp-server on start up
sudo nano /etc/rc.local --- add these line : --- sudo service hostapd stop sudo service isc-dhcp-server stop sudo ifdown wlan0 sudo ifup wlan0 sudo service hostapd restart sudo service isc-dhcp-server restart13. reboot
DLNA Server
1. install :
sudo apt-get install minidlna
2. configure :
sudo nano /etc/minidlna.conf --- # port for HTTP (descriptions, SOAP, media transfer) traffic port=8200 network_interface=wlan0 #Specify paths to directories containing digital media. media_dir=A,/media/stream/Music media_dir=V,/media/stream/Videos media_dir=P,/media/stream/Pictures friendly_name=Media Server db_dir=/mnt/tmp/minidlna album_art_names=Cover.jpg/cover.jpg/AlbumArtSmall.jpg/albumartsmall.jpg/AlbumArt.jpg/albumart.jpg/Album.jpg/album.jpg/Folder.jpg/folder.jpg/Thumb.jpg/thumb.jpg inotify=yes enable_tivo=no strict_dlna=no presentation_url=http://192.168.10.1:8200/ notify_interval=900 serial=12345678 model_number=1
3. start / restart the service
sudo service minidlna force-reload
