Copy protection serial number stuff

[theun]

Hi Aliasant,

There is a simple command line tool to find the MAC addresses in use on a PC.

First go to the "run" box in the start menu, then type "cmd" followed by <enter>.
Now type "ipconfig /all" followed by <enter>

However, SM finds 7 MAC addresses, of which I can identify sofar only 3.
5th is my ethernet card,
6th wireless
7th "Teredo tunneling pseudo-interface"

ipconfig finds only 6! And "Technitium" only 2.

B.t.w. I am 90% sure (but can't proof it as I didn't save anything) that the MAC primitive yesterday returned 8 MAC addresses on this PC.

It seems to me that the MAC primitive as it is now is not really usable,

Cheers!

No shit. Thanx Theun.

I ran that command and it listed my BT and my two ethernet cards. Same as SM.
Then it listed some other stuff including Teredo Tunneling Pseudo blablaba.
It doesnt really matter what it lists as long as it lists the same every time.

What it didnt list are those first 2 entries that SM reports.


Odd maybe?
Seems very unreliable =(

On the other hand the Mac serial has been steady for me. Keeps reporting the same even though I have 3 drives now.
Is that the case for every one else?

If it is I will keep using that one and skip the MAC for now.
If not I guess Ill do what AM thinks about. Skip it.
Unless we can dig up another unique number from our computers ?

Maybe we should only use the last reported MAC? The one after the last comma?

That is a VERY good idea. I have to do something else right now, but later (or maybe tomorrow) I'll
implement this into my coding.

No...

dosn't work because a virtual NW-Card is reported at last on my XP...

Thats it then. Its useless =/
Unless you strip the first say 5 characters + the all the commas and dots.
Then add all the individual numbers left together. 3+7+1+6+4+4+8 and so on.
It doesnt matter what order they are in. the sum will always be the same.

hi guys,

try this in command line getmac /fo table /nh > c:\MAcAddress.txt

Returns the media access control (MAC) address and list of network protocols associated with each address for all network cards in each computer, either locally or across a network.

maybe can help, instead of taking them from SM, you can import ...

I guess getmac uses the same system API call malc uses, but maybe one of you
guys with the problems can test this.

My result is this:
00-17-F2-0F-DE-C4 Media disconnected
00-17-F2-0F-DE-C5 \Device\Tcpip_{CEE93214-DDF9-4725-B432-8D461981A623}
00-16-CB-25-91-23 Media disconnected


These are my main ethernet cards and the last one is my bluetooth card.
Hope it helps.

aliasant this figure changes on each reboot or remain stable?
this is a link http://www.coffer.com/mac_find/ that indicates the Vendor based on Mac Address,
the reference runs only on the first 6 characters, and actually appear all of Apple.

If it remains stable, we could use this instead of GetMac of SM, informing of these difficulties to Malc, do not you think?

I agree. If others report the same. My numbers should be stable the one that changes on every reboot is not in that list.
Lets see what the others are saying. Could be nice to have a few more tests

Interesting, the getmac command returns only the 2 real network cards, first is the wireless, 2nd the ethernet card.

00-C0-A8-DD-FC-04 \Device\Tcpip_{22289820-660E-4488-B106-BCD1F4E64F1C}
00-1A-92-D1-DC-CF Verbinding met medium verbroken

Another thought is that from what i've seen sofar, most of the pseudo/virtual/whatsmore generated #'s can quite easily be rejected as a valid MAC number. Some of the numbers the MAC primitive returns here are e.g.

50-50-54-50-30-30,
33-50-6F-45-30-30,
38-C3-20-52-41-53,
20-41-53-59-4E-FF

whilst only OUI numbers (manufacturer ID's) have been issued, that start with 00 (>95 % seems to start with 00), 02, 04, 08, 10, 11, A0, AA and AC.

So you can almost see at a glance that the 4 MAC adresses listed are invalid.
Though many invalid MAC numbers can be eliminated quickly, the real trouble is of course in the categories that start with a valid number. Thousands, maybe tenthousands of these OUI's have been issued. Here is the complete list (is maintained on a daily basis!):http://standards.ieee.org/regauth/oui/oui.txt

O.K enough for today again ...

Cheers!

brilliant idea, I think!

I made a working osm that outputs the MAC adressess found by getmac.
It will return max 5 addresses, seems enough to me ..
It deletes the txt file after finishing. Though it still doesn't feel right writing in the C: directory.

I hope this is useful,

Cheers!

It is brilliant. I need to learn some of these command tricks.

One Q. When I run this it gives me 3 cards. But the whole series of numbers ends with 2 commas.
Is that ok?

I hate 2 put a damper again on the getmac idea:
