== 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.
