| any MAC address spoofing software on XP?
Sometimes I connect to the Internet thru open access points anywhere (cafe's, shops, schools, etc.). I want to falsify my MAC address for privacy reason. Anyone knows a good software to spoof or falsify my MAC address? |

I'm confused. How would altering your MAC address provide any privacy? Your data stream is being transmitted in the clear when using an open hotspot which, I would think, is of greater concern. VPNs can protect the data, firewalls can protect against unwanted connections, but spoofing a MAC addy does neither.

Providing that you select a valid MAC address, why would changing it be unacceptable? It is no different than changing to a new nic.

Changing it would prevent a free WISP from collecting usage data.
Many network card drivers provide this feature under Properties, Configure..., Advanced tab. If not, it can be modified in the registry. There are also programs to change the registry for you. e.g »www.klcconsulting.net/smac/ |

Not knowing what Client cards you have, all Linksys client cards On the Advance Tab, in the configure section of the Network Connections, allow you to change your MAC address on the fly |

Didn't think about that. Could they really tie it back to an individual if it was a free service, though? (If it's a paid service, I assume they already have my usage info.) Seems like a lot of work to keep them from knowing that 00:a0:f4:99:7d was here.

Okay this is slightly off-topic but still relates to MAC addressing....
A lot of folks here say that MAC spoofing is possible so setting MAC filtering on a WAP doesn't prevent it. But, if you have one wireless client, and that MAC is the only one set in the MAC filtering, if someone did figure it out and spoof the MAC, wouldn't both clients crash? Reasoning being that MAC's HAVE to be unique. I remember a news article somewhere back in 1996 or 1997 about two manufacturers of network equipment using a block of the same MAC addresses and that it would cause major issues.
Or is there a flaw in my logic? Once again, I apologize for the left turn I took here but this has been on my mind.

| You are correct. Attack methodologies using spoofed MAC addresses usually involve forcing the AP to disassociate, giving the attacker a way in. For a man-in-the-middle attack, this is followed with a re-associate with the bumped client.

| Hotspot don't have rules falsifying MAC address is not allowed. I know simple solution. I'll load Linux in my laptop! I already got a Perl program to randomize falsified MAC address. |

I busted our network administrator tracking us by our MAC address. So I stopped using XP and boot Linux instead, run a Perl program to falsify MAC address. It works. |
