how to change mac adress ?
 
hi
i was using a laptop before at my school's network. Now i changed my laptop and installed latest version of kubuntu. But the problem is without changing my mac address, i cant use internet. So i changed the mac adress by a command but i dont want to use commands everytime i start the computer. So my question is, What should i do to change the mac adress of the computer automatically ?

i tried to add this line:
Code:
hwadress ether 00:macadress
at : /etc/network/interfaces
Didnt Work..
also tried many lines there but didnt work

Can someone tell me please what line should i add to where to change my mac adress ?

Thanks in advance.

It should just be:
hwaddress ether XX:XX:XX:XX:XX:XX
within your interface stanza

Otherwise you might try a pre-up with:
ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX

pinniped i tried that one .. But unfortunately it didnt work.
i wrote

my /etc/network/interfaces file is :
Code:
auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0


iface eth0 inet static
address 10.whatelse
netmask 255.whatelse
gateway 10.whatelse
hwaddress ether 00:whatelse

auto eth0
it does not work.

Where should i write ?
Code:
ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX

Can't you just tell the person who runs your school's network your new computer's MAC address?

So you're trying to circumvent the rules?

In the interfaces file, just put:

pre-up /sbin/ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX

You can also ignore the ifup/ifdown scripts altogether and just configure everything with ifconfig somewhere in the network startup scripts.

So get the network admin to keep the old and add the new.

No, you are the one in the wrong, don't blame the tool maker for the poor tradesman.;
