Asus doesn't "build" computers :) Foxconn does. And also does Apple and Intel gear (AFAIK). And on the laptop market, at least some years ago, Quanta (Taiwan) had allegedly assembled 30% of all the sold laptops. You can usually spot this by checking the MAC address on the ethernet card (see http://www.coffer.com/mac_find... ).

They may not have built the entire system, but the system board has 'ASUS' written all over it.

The hardware address is in the packet before encryption. Set up a Linux box with Arpwatch and OpenVPN and see for yourself.

I don't know your level of knowledge so bear with me here. One approach would be to look up MAC addresses. Every network card has a code for the manufacturer listed in its MAC address. It's the first six characters. Any address starting with the following would be made by Huawei (1). For example, it may say "Dell" on the front, but if it starts with the below, its Huawei. If you manage a LAN you can compare to the list below. Can one clone/fake MAC addresses? Yes. However, if you run a LAN, I'd like to think you have the authority or knowledge to know if that's going on.

• 000FE2
• 001882
• 001E10
• 0022A1
• 002568
• 00259E
• 00E0FC
• 286ED4
• 6416F0
• 781DBA

Second, at the risk of pointing out the obvious, you could check their products page(2). Danger: Flash and scripts. As partners go, Huawei has at least two: 3Com and Symantec. 3Com's agreement on the surface seems to be a way for them to access the China markets. Symantec and Huawei announced a "joint cloud strategy" selling enterprise NAS products in the US market for starters. Hope this helps!

Only on Slashdot will someone call you out for faking your own MAC address: 0F:BA:29 lookup

4. MAC address ARE NOT UNIQUE! They are nearly unique, but if you operate under the idea that mac addresses are unique then your life will be hell when you have to track down a duplicate MAC on a large enterprise network because you believe it cannot happen. It does, although infrequently, and it makes networking very very 'interesting' when it happens.

I've always wondered how prevalent this is. The most significant 24bits are the vendor ID and the least significant are "supposed" to be unique within that vendor. Larger vendors have more then one vendor ID. So does a large NIC manufacturer reuse those lower 24 bits frequently? You can do a lookup for vendor IDs here: http://coffer.com/mac_find/

Had ~3000 Dell PCs on an enterprise network. Our routers were having a problem because the Broadcom chips we were using hash the layer 2 table index based on the SA and VLAN. Buckets were 8 entries deep. Well, take ~3000 MACs with the same upper 24 bits and we had conflicts. Even though the MSBs were the same, don't remember seeing the LSBs repeating. Of course 3000 is easy to randomly fit into ~16 million.

Duplicate MAC address seems seriously lazy to me. Even if the spec didn't say that manufacturers were supposed to provide globally unique IDs, the YY:YY:YY part of XX:XX:XX:YY:YY:YY is still 2^24 = 16,777,216 addresses -- you wouldn't think it would be that hard to find unused address. And according to coffer.com 3com has a whole slew of vendor codes, so they shouldn't even have to roll around at 16.7 million: http://www.coffer.com/mac_find/?string=3com.

I'd disagree with your disagreement. :-)

Will tell you the make of any WAP just from it's ethernet address. You don't even need to associate with it.

That's somewhat correct. The MAC address is burned into the hardware, and you really can't actually change it. This being said, the OS does read it, and many OS's allow you to simulate the change in software. This doesn't actually change the address, as if you put the card in another computer, it will revert to the actual MAC (unless that OS is also configured to simulate a MAC change).

Also, part of the MAC (The first half, I believe) tells which manufacturer made the equipment. You can look up the manufacturer for a specific MAC here.

and frankly this scares the hell out of me.

I have played with these. First of all, they are simply locked down so they will work with almost any Cisco MAC address. Other than that they are completely open.

Once you connect to the AP, you can either telnet directly to the DB server and pull any records you wany, or you can connect to any other PD in Washington State (AFAIK). Atleast all the ones around here. It's basicly a huge private IP network using T1s, fractional T1s, and ISDN lines, all linking back to Olympia.

Funniest part was when I got a call from the main office asking me to scan everything for viruses ASAP, since the windows-worm-of-the-week was making its rounds on the secure network.

I'd too would prefer they'd be made some dope-smoking hacker instead.

This is no joke:

Our MAC addresses start with 00:04:20

And no, you can't specifically request a "vanity" MAC prefix. :)
