Ray, you are right in most of your affirmation.
I had done it ONCE using EigerStein and an 3Com Etherlink 3 ISA (I think...) The command I used to change the MAC was: ip link set eth0 address ff:ff:ff:ff:ff:ff You will need to change the FF... to the correct MAC that you want to fake. Next, you need add this to one of the startup scripts, can't recall which... Maybe from this info you can extrapolate other scenarios :) -----Original Message----- From: Ray Olszewski [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 12, 2002 5:22 PM To: [EMAIL PROTECTED] Subject: Re: [leaf-user] LRP Bering / change nic mac address At 08:23 AM 9/12/02 -0700, Tom Eastep wrote: >On Thursday 12 September 2002 03:05 am, Lennard de Hoog wrote: > > Blaise, > > > > the mac address is in the Nic, there is no way to change a mac > > address. > > > > so you can't fix or change the mac address. > > > >Not so -- most drivers allow overriding the manufacture-provided MAC >address. Some Linux NIC drivers (modules) do, and some don't. For the ones that do, some NICs are said to honor the change (at the firmware level), while others don't (that is, the NIC itself needs to be set promisc, and the kernel/driver sorts things out). It would be quite valuable (to cable-modem users, and perhaps others) if we could, collectively, create a listing of which NICs do allow reseting of the MAC address at the firmware level. I personally do not know of *any* NICs that do this (that is why I wrote "said to" above) ... but since I've never had a connection that used MAC-address authentication, it has never been a priority for me. So how about it, folks? Would anyone who has actually made MAC-address spoofing work at the firmware level (that is, without using promisc) tell us about it -- what NIC, what module (driver), and what tricky details to make it actually work? And what LEAF version, if that matters to success. -- -------------------------------------------"Never tell me the odds!"-------- Ray Olszewski -- Han Solo Palo Alto, California, USA [EMAIL PROTECTED] ---------------------------------------------------------------------------- --- ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html
