== Creating an Ad-hoc Network ==

'''On startup using the interfaces file:'''

Open <code>/etc/network/interfaces</code>

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

Reboot

'''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:

 vi /etc/udhcpd.conf

Put the following in the file:

<code><pre>
#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
</pre></code>

Create the leases file:

 touch /var/lib/misc/udhcpd.leases

Now run the dhcp server:

 udhcpd /etc/udhcpd.conf

Connect to the gumstix ad-hoc network and you should notice that you have been assigned the start address in the config file above.
