MAC Address

:( I saw a source code for a program somewhere, that using a series of ping and traceroute commands through vb could find a MAC Address from an IP. Now I've lost the source :mad: . If anybody knows where to find this source or knows how to do it in C, C++, C#, VB, or VS.NET it would be very much appreciated! :D

And what, pray tell, would you need someone's MAC address for? I don't have the source fora any such program and, honestly, don't think that something like that can be done using just ping and traceroute... It would take a lot more than just those two utilities in order to get someone's MAC address. And if you're asking this with any malicious intent, I'd recommend searching elsewhere.

It's impossible to get the MAC address of someone on a diffrent ethernet segment (using ip headers...) unless that host gives it's MAC away in an higher level protocol (like netbios or something... I believe blackice does something like that...)

I'm not trying to do anything with malicious intent, I'm simply in the search of knowledge.

If you have WINDOWS95/me you can do a search for netbios names

Just run command prompt and type in

NBTSTAT -A (then the IP address if you know it) then press return/enter.

you will get something that looks like this



Lana # 0:
Node IpAddress: [xx.xx.xxx.xxx] Scope Id: []

NetBIOS Remote Machine Name Table

Name Type Status
---------------------------------------------
COMPUTER_NAME <00> UNIQUE Registered
DOMAIN <00> GROUP Registered
COMPUTER_NAME <03> UNIQUE Registered
COMPUTER_NAME <03> UNIQUE Registered

MAC Address = xx-xx-xx-xx-xx-xx

Alot of people already know about this though :)

Mac address only exist from one hope to the next so unless the computer is on a local network or a progam like netbios sends you the info theres no way to get it.

Hmmm....
What whoud you use the MAC adress to..... Maybe there are some exploits for it some buffer overflows... But i don't know them....
