13. Til sanna the breyting of MAC address, go to command prompt, then type in one of the following commands:

    ipconfig all
    net config rdr

Note: To restore or reset back to true original hardware burned-in MAC address, remove the NetworkAddress registry key that is been added.

Alternative: Third party tools and utilities to change the MAC address in Windows operating system are plenty, for example: SMAC (direct download link to smac20_setup.ex, supports Windows Vista, XP, 2003, 2000), Macshift (direct download link to macshift.zip, for Windows XP), BMAC (almost identical SMAC MAC changer clone by moorer-software.com), Mac MakeUp (direct download link to macmakeup.zip, for Windows 2000/XP/2003/Vista), MadMACs (MAC Address Spoofing And Host Name Randomizing App For Windows, directly download MadMACs.zip), EtherChange (direct download link to etherchange.exe), and Technitium MAC Address Changer (for Windows 2000 XP Server 2003 Vista Server 2008).

How to Change MAC Address (MAC Spoofing) in Linux and *nix

To change your MAC address in Linux and most Unix-like (*nix) system, run the following script commands:

ifconfig <interface> down

ifconfig <interface> hw <class> <MAC address>

ifconfig <interface> up

For example, the command looks lik “ifconfig eth0 down hw ether 1A:2B:3C:4D:5E:6F”. First command brings down the network interface, second command change its MAC address while third command bring up the interface again. Note that in some cases, to bring down and bring up the network interface, the following commands have to be used:

etc/init.d/networking stop or etc/init.d/network stop (in the case of Fedora Core 5)

etc/init.d/networking start or etc/init.d/network stop (in the case of Fedora Core 5)

Alternatively, for Fedora Code 5 Linux with Iproute2 tools installed, the following commands also can change the MAC address to spoofed version:

etc/init.d/network stop

ip link set <interface> address 1A:2B:3C:4D:5E:6F

etc/init.d/network start

For example, “ip link set eth0 address 1A:2B:3C:4D:5E:6F”. To check whether the MAC address has been spoofed, use ip link ls eth0 or ip addr ls eth0 instead of using ifconfig eth0.

How to Make the Spoofed MAC Address Permanently Even After Reboot in Linux

Edit the ifcfg-eth0 file (or other similar file if you’re changing different interface), add the following variable line to the file:

MACADDR=12:34:56:78:90:ab

Then run service network restart to make the change effective immediately.

How to Make the Spoofed MAC Address Permanently on Restart in Debian

Edit the /etc/network/interfaces file and add in the following variable line to the appropriate section so that the MAC address is set when the network device is started.

hwaddress <interface> 02:01:02:03:04:08

For example, “hwaddress ether 02:01:02:03:04:08″.

Alternative: GNU Mac Changer (for Debian, Slackware, ArchLinux, Mandrake, Crux and other RPM-based distributions such as Fedora, Red Hat, CentOS, ASPLinux, SUSE Linux, OpenSUSE and etc.

How to Change MAC Address (MAC Spoofing) in BSD or FreeBSD

Issue the following commands in shell:

ifconfig <interface> down

ifconfig <interface> <class> <MAC address>

ifconfig <interface> up

First command brings down the network interface (optional), second command change its MAC address while third command bring up the interface again (optional). For example, the command looks lik “ifconfig xl0 link 1A:2B:3C:4D:5E:6F” or “ifconfig fxp0 ether 1A:2B:3C:4D:5E:6F”

How to Change MAC address in Solaris

The shell command to change the MAC address in Sun Solaris is as below:

ifconfig <interface> <class> <address>

For example, the command looks like “ifconfig hme0 ether 1A:2B:3C:4D:5E:6F”. Note that the change is temporary that does not persist after a reboot. To make this change permanent, the command can be placed in a runtime control script (/sbin/sh).

How to Spoof MAC Address in HP-UX

It’s possible to change MAC address using HP-UX SAM. Select Networking and Communications, then selecting the interface, then click on Action > Modify > Advanced Options. Finally, change the value of station address, which is MAC address name in HP-UX.

How to Spoof and Change MAC Address in OpenBSD

Use the following command to change MAC Address to spoofed MAC in OpenBSD (after version 3.8):

ifconfig <interface> lladdr <MAC address>

For example, “ifconfig bge3 lladdr 1A:2B:3C:4D:5E:6F”.

How to Change to Spoofed MAC Address Permanently in OpenBSD

To make the MAC address changed at boot before network connection is established, and even before parsing of hostname.* file, edit the /etc/netstart file to add in the following lines before the line of “# Now parse the hostname.* file”:

if [ "$if" = "INTERFACE" ]; then
ifconfig <interface> lladdr <MAC address in format of 00:00:00:00:00:00>
fi

# Now parse the hostname.* file
....

How to Change MAC Address in Mac OS X

Since Mac OS X 10.4.x (Darwin 8.x) onwards, the MAC address of wired Ethernet interface can be altered in Apple Mac OS X in a fashion similar to the Linux and FreeBSD methods. To do so, type the following command in Terminal.app:

sudo ifconfig en0 ether aa:bb:cc:dd:ee:ff

or

sudo ifconfig en0 lladdr aa:bb:cc:dd:ee:ff (for Mac OS X 10.5 Leopard)

where en0 is the network interface (numbered from en0, en1, en2 …) and aa:bb:cc:dd:ee:ff is the desired MAC address in hex notation.
