Hi,

is there a known way to edit my network card's h/w address?


Depends on your operating system and/or the software provided for your
NIC. There are some NICs where you flash it to change its hardcoded MAC
address but very folks have those. It's easier to change it in the
operating system.

Hmm, that's interesting. Could you be a bit more specific. Change it in
the OS. I admit I cannot follow here. My OS is Linux BTW.

First hit Googling on 'linux mac address':

"If you don't know the MAC Address, it is easily obtained. Simply enter
the following command from the Linux command line:

# /sbin/ifconfig -a"

And second hit has the above info for almost every OS under the sun:

Here's how to change it under linux:

"ifconfig hw ether xx:xx:xx:xx:xx:xx"

I asked which operating system because you didn't specify what you use.
I use Windows XP and to change the OS-reported MAC address means to
change a property of the NIC device under the Device Manager. The other
poster told you how to do it under Linux. It was a surprise to me, too,
when I first heard about it. I knew there were a few NICs where you
could flash them to program in a new MAC address (we had some around
work but forgot why we needed to change their MAC address). Later I
found out about changing it in the OS and that is much easier.
Unfortunately that means any admin-privileged user on the OS can change
the MAC at-will and that used to be hard signature of a host (you ran
into problems of having the reauthenticate to a domain if you changed
your NIC).

Hard signature - this is what I believed it to be. Thanks, and thanks to
dion.
