sudo ifconfig en1 ether (mac-address)
*this will spoof your mac-address*
ifconfig en1 |grep ether
*this will show you your current mac-address*

All the time I was using the ifconfig method in some /etc/init.d startup scripts (without changemac program), but now i tried the solution from original post and i find it the best. It’s very clean, i just added the line “hwaddress ether 01:02:03:04:05:06″ to /etc/network/interfaces and after restart everything works like a charm…

try this:

sudo gedit /etc/init.d/bootmisc.sh

on the bottom of the page, insert:

killall dhclient
killall dhclient3
ifconfig eth0 down
ifconfig eth0 hw ether 112233445566
ifconfig eth0 up
/sbin/dhclient
/sbin/dhclient3

anything in this file will load after the regular boot process is started up. So putting this in the file will change the mac address everytime the machine starts.

this one worked in the newest Ubuntu distro year 2009 jan/feb.

Open terminal and type as follow:

$ ifconfig

$ cd /etc/init.d

$ sudo nano ChangeMAC

Then, fill configuration file with new MAC Address.
sudo ifconfig eth1 down
sudo ifconfig eth1 hw ether xx:xx:xx:xx:xx:xx
sudo ifconfig eth1 up
sudo /etc/init.d/networking stop
sudo /etc/init.d/networking restart

Save and close the file

Apply configuration file.
$ sudo chmod +x ChangeMAC

$ sudo update-rc.d ChangeMAC defaults

Restart machine, and check new MAC Address with ifconfig command.

Hi,
Tried all the options (not together ), but no one didn’t fix the problem for me.
with ipconfig I still have my eth0 with my old mac adress.
Anyone new ideas?
Thanks,

Jhom

small typo in last line of DX’s script, should be /etc/iniT.d/networking restart

thanks, btw!

@DX

Thanks for the update, I’ll test and change the article. I’m guessing when I wrote this it worked for an older version of Ubuntu, but not anymore.
