Raspberry Pi Study Notes (1) -- Rasbian Wireless Network Configuration

Objective: To use a wired connection network and use Mentohust to authenticate ruijie. the wireless network is configured as AP hotspot shared Internet access.

1. configure a wired network

Edit

  nano /etc/network/interfaces

Comment out DHCP and configure static IP addresses and MAC addresses

:XX:XX:XX...

Configure DNS Server

  nano /etc/resolv.conf

Add a Google Dns address

nameserver ..

Save and restart the network service

  /etc/init.d/networking restart

Ii. Install Mentohust

Install libpcap first

  apt-get  libpcap-dev

  apt-get  autotools-dev libgtk2.-dev libscim-dev libtool automake1.

Mentohust source code preparation

 git clone https:   autogen.

Compile and install

 ./configure --prefix=/  &&   

Grant Super User Permissions to programs (optional)

   u+s /usr/bin/mentohust

Configure Mentohust

Welcome to the MentoHUST version :. ---- k -------- g gateway [Default 0 .. -s DNS [Default 0 .. -o Ping host [Default 0 .. ----- a multicast address: (standard) (ruijie)-d DHCP mode: (not used) (Secondary authentication) (after authentication)-B running in the background: (No) (Yes, disable the output) (yes, retain the output)-y show notification: (NO )~ ---- Q: SuConfig is displayed. dat content (for example,-q/path/-uusername-ppassword-neth0-i192 .. -m255 .. -g0 .. -s0 .. -o0 .. -t8-e30-r15-a0-d1-b0-v4.-fdefault. mpf-

3. configure a wireless network

Install wireless NIC Driver, take EDUP EP-N8508GS, 8188cuz chip as an example.

Obtain the source code of the kernel header.

  cd /usr/  https:  xvfz rpi-.y. KVER=` -  linux-rpi-.y linux- cd linux-$KVER/  -i   /proc/config.gz >  https:    -s /usr/src/linux-$KVER /usr/src/  -s /usr/src/linux-$KVER /lib/modules/$KVER/  -s /usr/src/linux-$KVER /lib/modules/$KVER/ exit

  http:  RTL8192xC_USB_linux_v3..4_4749.. cd RTL8188C_8192C_USB_linux_v3..4_4749./driver/ upzip rtl8188C_8192C_usb_linux_v3..4_4749.. cd rtl8188C_8192C_usb_linux_v3..4_4749.

Modify the Makefile file and find the following configuration. The default configuration is i386.

  nano Makefile

====

Set the above

 

=====

 

Add the following configuration to a file similar

+= -=== $(shell  -= /lib/modules/$(KVER)/= /lib/modules/$(KVER)/kernel/drivers/net/wireless/=

After modification, save and exit, you can start compilation and installation.

  &&   

After installation, the module name is 8192cu. ko. After loading the module, the NIC can be used normally.

   8192cu.ko

4. configure a wireless network

Configure static IP addresses for wireless networks first

  nano /etc/network/interfaces

Add the following content

#allow-...-roam /etc/wpa_supplicant/

  https:  -zxvf v1.. cd RTL8188-hostapd-/  &&   

  vim /etc/default/hostapd

DAEMON_CONF=

  vim /etc/hostapd/hostapd.conf

To:

========-=WPA-=====

  [ ok ] Stopping advanced IEEE  [ ok ] Starting advanced IEEE  management: hostapd.

V,

  apt-get  isc-dhcp-   /etc/dhcp/dhcpd.conf  /etc/dhcp/  nano /etc/dhcp/dhcpd.conf

default-lease- -lease- -. netmask .. ..-address .-name-servers .,.-lease- -lease- 

  service  isc-dhcp-server restart

VI,

  iptables -  iptables -  iptables -t nat -A POSTROUTING -o eth0 -  iptables-save > /etc/ exit

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

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

    /etc/network/-pre-up.d/iptables

  nano /etc/sysctl.conf

# Uncomment the next line to enable packet forwarding =

  sysctl -p

7. Add auto-start upon startup

Complete the above steps,

  apt-  chkconfig --  chkconfig --add isc-dhcp-server

Well, all the configurations are complete. This is very suitable for students who use ruijie on campus networks. It is much more interesting than buying a vro. Raspberry Pi is still very powerful. I hope more partners will study it with me.
