Change your Network Card MAC Address on Ubuntu
There are a lot of reasons you might want to manually set your MAC address for your network card. I won't ask you what your reason is.
To change this setting, we'll need to edit the /etc/network/interfaces file. You can choose to use a different editor if you'd like.
sudo gedit /etc/network/interfaces
You should see the line for your network interface, which is usually eth0. If you have dhcp enabled, it will look like this:
auto eth0
iface eth0 inet dhcp
Just add another line below it to make it look something like this:
auto eth0
iface eth0 inet dhcp
hwaddress ether 01:02:03:04:05:06
Obviously you would want to choose something else for the MAC address, but it needs to be in the same format.
sudo /etc/init.d/networking restart
You will need to restart networking or reboot to take effect.
Try to apt-get macchanger. Much easier to use.
via bash:
1) sudo ifconfig down
2) sudo ifconfig hw ether 11:22:33:44:55:66
3) sudo ifconfig up
thats it
The ifconfig method will only temporarily change your mac address.
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 script is good. But not working localhost & azureus etc.
You must apply:
sudo gedit /etc/network/interfaces
And paste in this file:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
hwaddress ether XX:XX:XX:XX:XX:XX
The tutorial dosn't work for me. Don't know why.
Then I tryed procuro's method and it works but just for a minute. Then my laptop dies, gets blocked and I can't do nothing.
I have a wired connection and generated ip.
I found this:
****************************************************************
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/ini.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.
****************************************************************
WORKS JUST FINE!
@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.
small typo in last line of DX's script, should be /etc/iniT.d/networking restart
thanks, btw!
