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 !!

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?

I did not test it with a license manager ,
but i think it should work !

I'll make the test .

I've tried to generate a license with EFALicGen with
node lock 000011223344 then i changed my Mac address
with ifconfig
# ifconfig eth0 down
# ifconfig eth0 hw ether 00:00:11:22:33:44 up
And then i lauched the software ...
It works !!

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

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

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.
