1, install the required package

sudo apt-get install Hostpad UHDCPD

2. Configuring the/etc/network/interfaces File

Configure Wlan0 as static address

The format is as follows:

Iface wlan0 inet Static

Address 192.168.10.1

Netmask 255.255.255.0

Save, exit

3. Configuring the/etc/udhcpd.conf File

Set up automatic assignment of address ranges for DNS gateways, etc.

Specific as follows: (according to individual needs to configure)

Start 192.168.10.2 # This is the range of IPs that the Hostspot would give to client devices.

End 192.168.10.200

Interface Wlan0 # The device udhcp listens on.

Remaining Yes

Opt DNS 8.8.8.8 8.8.4.4 # The DNS servers client devices would use.

opt subnet 255.255.255.0

< EM id= "__mcedel" > opt Router 192.168.10.1 # The Pi ' s IP address on wlan0 which we'll set up shortly.

opt Lease 864000 # ten day DHCP lease time in seconds

4, sudo vim/etc/default/hostpad

Will

#DAEMON_CONF = "" instead

daemon_conf= "/etc/hostapd/hostapd.conf"

5. Edit/etc/hostapd/hostapd.conf

As follows:

1. # Wlan0 the wireless card as an access point
2. Interface=wlan0
3. # using nl80211 Driver
4. driver=nl80211 (some may be rtl871xdrv, I can't, hint "unknown")
5. #共享网络的SSID是RaspberryPi
6. Ssid=raspberrypi (WiFi name)
7. # NIC works in 802.11G mode
8. Hw_mode=g
9. #无线网卡选用11信道
10. channel=11
11. # WPA2 Configuration
12. wpa=2
13. #wpa密码是raspberry
14. Wpa_passphrase=raspberry (wifi password)
15. #认证方式为WPA-psk encryption method is CCMP
16. Wpa_key_mgmt=wpa-psk
17. wpa_pairwise=ccmp
18. rsn_pairwise=ccmp
19. beacon_int=100
20. Auth_algs=3
21. Wmm_enabled=1

6. Edit/ETC/DEFAULT/UDHCPD

Comment it out

#DHCPD_ENABLED =no

7. Configure Route forwarding

The next step is to forward the data from the wireless card wlan0 to the wired card eth0 above the internet via a wired network connection.

Because eth0 is the dynamic IP that is acquired, this is accomplished by Iptables for simple route forwarding.

Input command

1. sudo iptables-f
2. sudo iptables-x
3. sudo iptables-t nat-a postrouting-o eth0-j Masquerade
4. sudo bash
5. Iptables-save >/etc/iptables.up.rules
6. Exit

Copy Code

Input command

1. sudo nano/etc/network/if-pre-up.d/iptables

Copy Code

Copy and paste the following two lines into the edit window

1. #!/bin/bash
2. /sbin/iptables-restore </etc/iptables.up.rules

Copy Code

Save exit
Input command

1. sudo chmod 755/etc/network/if-pre-up.d/iptables

Copy Code

Turn on kernel forwarding
Input command

1. sudo nano/etc/sysctl.conf

Copy Code

Find this place

1. # Uncomment the next line to enable packet forwarding for IPV4
2. #net. ipv4.ip_forward=1

Copy Code

Get rid of the Net.ipv4.ip_forward front #
Save exit

Input command

1. sudo sysctl-p

Copy Code

8. Set the service to boot mode

sudo update-rc.d HOSTAPD enable

sudo update-rc.d UDHCPD enable

After that, restart the machine, use mobile phone should be able to see the WiFi set, after connecting, access the following extranet to see if it is available
