Creating an Ad-hoc Network
On startup using the interfaces file:
Change the wlan0 config to
auto wlan0 iface wlan0 inet static address 192.168.2.2 netmask 255.255.255.0 wireless-mode ad-hoc wireless-essid gumstix-network
Using ifconfig and iwconfig:
ifconfig wlan0 down ifconfig wlan0 address 192.168.2.2 netmask 255.255.255.0 iwconfig wlan0 mode ad-hoc essid gumstix-network ifconfig wlan0 up
Running DHCP Server on Ad-hoc Network
Setting up a DHCP server on the ad-hoc network will allow you to connect to the gumstix without having to change your ip address.
Create a configuration file:
Put the following in the file:
#start address start 192.168.2.3 #end address end 192.168.2.254 #interface to listen on interface wlan0 #maximum number of leases max_leases 64
Create the leases file:
Now run the dhcp server:
Connect to the gumstix ad-hoc network and you should notice that you have been assigned the start address in the config file above. .
