Reconstruction of wireless router based on Raspberry Pi

It is estimated that the impact of the typhoon yesterday, the home of the slag route strike, can only link but not the Internet. Originally intended to surf the internet to come back, the results of last night to pick up things when the university bought a face recognition of the Raspberry Pi in the corner to eat ash for a long time, so intends to transform it.

Too long did not move the Raspberry Pi, power does not run normally, simply directly from the first step of the brush system to start operation.

First, system settings

Brush system operation has been introduced a lot, here reference @ Wang Dengko: HTTP://WWW.TUICOOL.COM/ARTICLES/RBVNFEF Implementation Putty Remote Connection Raspberry Pi

Second, HOSTAPD

1, installation HOSTAPD

sudo Install HOSTAPD

2. Use the following statement to open HOSTAPD

sudo NANO/ETC/DEFAULT/HOSTAPD

3, find #daemon_conf= "" This line, first uncomment (remove the previous #), and then modify it to:

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

4. Open hostapd.conf

sudo nano/etc/hostapd/hostapd.conf

5, add the configuration information (PS: Because I did not find the specific type of equipment I bought, which is used in the following way to configure)

# Wlan0 The wireless card as an access point interface=Wlan0 # Use the corresponding driver driver=XXXX #共享网络的SSID是RaspberryPi SSID=Raspberrypi # NIC works in 802.11G mode Hw_mode=G #无线网卡选用11信道 Channel= One# WPA2 Configuring WPA=2#wpa密码是raspberry wpa_passphrase=Raspberry #认证方式为WPA-PSK Encryption mode is CCMP WPA_KEY_MGMT=wpa-PSK wpa_pairwise=CCMP rsn_pairwise=CCMP Beacon_int= -Auth_algs=3wmm_enabled=1

6, install Autoremove HOSTAPD

sudo apt-get autoremove HOSTAPD

7. Download and install third-party drivers:

wget https://tar -zxvf v1. 1. Tar . GZ cd RTL8188-hostapd-1.1/sudomakesudomake  Install

8. Start HOSTAPD Service:

Sudo

The following text indicates that the start was successful

802.11802.11 MANAGEMENT:HOSTAPD.

Open the hostapd.conf query to my configuration as follows

# Basic Configurationinterface=Wlan0ssid=Wifichannel=6#bridge=br0# WPA and WPA2 configurationmacaddr_acl=0Auth_algs=1Ignore_broadcast_ssid=0WPA=3Wpa_passphrase=Yourpasswordwpa_key_mgmt=wpa-pskwpa_pairwise=tkiprsn_pairwise=ccmp# Hardware configurationdriver=rtl871xdrvieee80211n=1Hw_mode=Gdevice_name=Rtl8192cumanufacturer=realtek

Third, DHCP

1. Install the DHCP service to assign IP to each access device

sudo Install Isc-dhcp-server

2. Edit the configuration file

sudo nano/etc/dhcp/dhcpd.conf

3, set the gateway and other information, here is the use of 10.38.10.1

default-lease- Time  -; Max-lease- Time 7200; log-facility LOCAL7; subnet10.38.10.0Netmask255.255.255.0{Range10.38.10.10 10.38.10.100; option Routers10.38.10.1; option broadcast-address10.38.10.127; option Domain-name-servers8.8.8.8,8.8.4.4; default-lease- Time  -; Max-lease- Time 7200; }

4. Start the DHCP service

sudo service isc-dhcp-server restart

Four, forwarding configuration

1. Configure route forwarding

sudo iptables-sudo iptables-sudo iptables-t nat-a postrouting-o eth0-
   
    sudo 
     bash iptables-save >/etc/
    iptables.up.rules exit
   

2. Open iptables File

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

Add the following code

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

3. Modify Iptables Permissions

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

4, set the kernel forwarding, open the sysctl.conf file

sudo nano/etc/sysctl.conf

Place the following two lines within the file

 for IPv4 #net. Ipv4.ip_forward=1

Modify to (that is, remove the net.ipv4.ip_forward=1 comment)

 for IPv4 Net.ipv4.ip_forward=1

5. After modifying the kernel, make it effective

sudo sysctl-p

At this point, the wireless router Setup function has been completed.

V. Self-starter settings

1, installation Chkconfig

sudo Install Chkconfig

2, set HOSTAPD, DHCP self-start

sudo chkconfig--sudo chkconfig--add isc-dhcp-server
