LinuxQuestions.org - Internet connection problem

Hi

I cannot connect to Internet. Here is the setting:

I am using LAN card/ ethernet co connect to I`net.
I am assigned IP through DHCP. I think the server assigns me the IP address according to my lan card's mac address. This worked under WinXP and Ubuntu.

But I recently got another PC and the DHCP server did not allow me to connect to internet.
So I changed my mac address in Ubuntu in the following way:

/etc/init.d/networking stop
ifconfig eth0 hw ether 00:11:2F:25:64:15
/etc/init.d/networking start

and it configured with DHCP automatically. The same was with windows on the new PC.

Today I installed SUSE 10 on the new PC and cannot connect.
As root I type this:

/etc/init.d/network stop
/etc/init.d/network start
and the latter says

lo IP address : 127.0.0.1
eth0 device intel. ............................
eth0 configuration: eth-id-00:11:11.............. my real MAC address
usb no configuration found

then i type:

/etc/init.d/network stop
ifconfig eth0 hw ether 00:11:2F:25:64:15
/etc/init.d/network start

but " /etc/init.d/network start " return the following:

lo IP address : 127.0.0.1
eth0 device intel. ............................
eth0 no configuration found
usb no configuration found

and so it could not configure with dhcp.

I tried also YAST but i did not see where to change my mac address
I am ready to enter my ip address manually but i am not quite sure where whaat to enter
But anyways, I must chande my MAC address.
so here are my manual settings from Ubuntu and Windows:

IP: 82.199.203.110
subnet: 255.255.255.224
def gateway: 82.199.203.97

dns server: 82.199.192.2 , 82.199.203.4

this is all i need to enter in Windows to have Internet.
There is something called Domain seach in Ubuntu "speedy.sellinet.net"

I would appreciate any kind of help.
Thanks in advance for the help,
