change ethernet address

It can be useful , to solv to license problems to change
your ethernet card address .

It can be done like this :

# ifconfig eth0 down
# ifconfig eth0 hw ether 11:22:33:44:55:66 up
# ifconfig eth0 | grep HWaddr
eth0 Link encap:Ethernet HWaddr 11:22:33:44:55:66

That 's ok !!
 

ifconfig eth0 hw ether

Do you try it? i change the mac address under windows 98 and windows 2000, the mac address is changed, but eda tools fail to get a license.
Does it success under solaris or other unix platform?

change ethernet address linux

It's only temp. to change the ether. address. After you reboot the system, the ether address become the org.
 

ether change

OK, It's easy .

At the top of the file ( /etc/rc.c/init.d/network ),

You can add a new line like this :
ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx

Good Luck !

changing ethernet address linux

Hi,

I don't have a network card, so I've heard that I can emulate one with:

modprobe dummy
ifconfig dummy0

I did that, and the device shows in the list, and I even changed the it's ethernet address from 000000000000 to one different than 0. The problem is that, even after doing this, the lmhostid program says: "The Ethernet address of this machine is:"" ".

Any idea? Is this procedure correct? Is here another one of getting an ethernet address when I don't have a Network card?

Thanks.
 

ifconfig eth0 hw ether

Hello Armer:
"ifconfig" work on linux platfom. And Solaris is not working. Someone may tell me can it work on freebsd?
 

set ethernet adress

modify /etc/sysconfig/network-scripts/ifcfg-eth0
delete line of HWADDR
add MACADDR line，below：
MACADDR=00:11:22:33:44:55


I test in RHEL4. is OK
 

linux change eth0 address

in RHEL4 I don't have such a file ifcfg-eth0
The closest name is "ifcfg-lo" no other 'ifcfg...' files
