But when you lunch as root: #ifconfig eth0 what happen? If there is your network-interface whit the same parameter for the ip-address and mac-address is right. But the service network is started? /etc/rc.c/init.d/network status the answer maybe is like this Configured devices: lo eth0 Currently active devices: lo eth0 If is like this is right, if in the Currently active devices there is only the loopback-interface it seams that your network is down and you must bring up whit the command : /etc/rc.c/init.d/network start Now you can try to ping yourself whit the IP-Address of your intranet and after you can try to ping the other machines.
