Good afternoon and greetings from Nigeria ,
please I am in need of help, assistance or walk-through on how to solve some 'perceived' problems with my toshiba laptop running ubuntu 8.04 and trying to share the internet connection on my wired lan (eth0) via my PRO/Wireless 3945ABG Network Connection wireless (wlan0) as an adhoc network with my nokia N95. I would be grateful if your assistance would be easy and/or simple enough.
The output from my ifconfig lists these

eth0 ... ...
lo ... ...
vnet0 ... ...
wlan0 ... ...
wlan0:avahi ... ...
wmaster0 ... ...

ps: ufw is enabled
