Hi everybody, thks for previous answer
i have another probleme.
I succeed to config the network card under KDE thanks to the wizard.
But know i want to configure it under fluxbox with the 'ifconfig' command line.
ip : 10.0.0.100
netmask : 255.0.0.0
so i know that it begin with : ifconfig eth0 10.0.0.100 netmask 255.0.0.0....
but i dont know the follow, especially how to include the nameserver(DNS)
if anyone know the perfect line, it will be great, thx again all.
