Ad-hoc network Creation


For running these routing protocols we need to configure our wireless card in ad-hoc mode. It must be a compulsory step for every running of routing protocol. The configuration steps were given below.
  • Ensure that network manager has been stopped and then bring the interface down.
    # /etc/init.d/Network-Manager stop
    # ifconfig wlan0 down
  • Switch the card into ad hoc mode
    # iwconfig wlan0 mode ad-hoc
  • Set the channel/frequency that you want to use.
    # iwconfig wlan0 channel 11
  • Bring the interface back up
    # ifconfig wlan0 up
  • Add the name (ssid) for the network you want to create/join. Use single quotes if there is a space in the name.
    # iwconfig wlan0 essid 'name'
  • Add a WEP encryption key
    #iwconfig wlan0 key 1234567890
  • If you want to do it manually, you will have to make up an IP address.
    # ifconfig wlan0 10.0.0.1 netmask 255.255.255.0
