how to send a message to other user using only MAC address?
824244
MAC address is the personal identifier of a network card.  It says who, not where.  Wireless uses MAC address because it is the perfect ID- It then assigns an IP to say where the signal goes.  It would be cool to have a net send for MAC, but I've never heard of it.

first you must have pc to pc connection...\n\nusing lan (local area network)\n\nby using RJ45 (crossover) cables you can connect two \n\ncomputer and can send message directly through it...\n\nbefore you can use those above command such as net\n\nsend...

You need to put the addresses in the BCC box (blind carbon copy). \nTo send the message put your own address in the "To" box

A MAC address is a predefined, but still changeable, hex number address of the network card inside your computer. A spoof is when someone changes thier computers MAC address to your address and attempts to gain access to your netwrok via this mac address. Yes public and private keys can help. Authentication is the only hope you have against mac address spoofing. EXAMPLE: A wireless router that is set up for access control looks at 3 things, the mac address, the computer name and a key (128 bit or cyphered) for authentication. If someone gets a mac and computer name of a system already authenticated to join the routers network the only thing keeping this computer from accessing your router is the keys. Preferably encryted keys. If you are talking crytography that would partain to, um, what, emails and that type of thing? Unless you are trying to trace a mac addy in en email address that is. Regardless of why u are tracking the mac addy, the use of keys for authentication of whatever the source is can possibly be the last line of defence to ensure the communication is from who it says it is supposed to be. but keep in mind that if someone, other than the person or computer who is legitimently supposed to have the keys, has the computer name and mac address you can probably bet that this person has the keys as well. If you think you are beeing mac spoofed and using keys, change the keys immeditely after the threat has been detected. This is only my opinion and not gospel, but i think it to be correct. Sometimes real world assesments look very different from text book assesments and the work around is totally different as well. Final thoughts: Get a land line phone and call whomever it is u want to securely communicate with when in doubt of a security breech. I hope I was helpful.

Encrypting is a good idea.  I'd also suggest you use the MAC Address filter.  Basically every communication device made contains a unique number to identify it.  You can set your router to allow only this number to connect and use it.\n\nTo figure out your MAC Address take a look at this link:\n\nWindows only:\nhttp://help.stargate.net/broadband/ipconfig.shtml\n\nWindows and everything else:\nhttp://www.artsci.wustl.edu/ASCC/documentation/macaddrss.html

There are a few cross-platform VoIP applications you can choose from.  Skype is very good, but also give Gizmo a try.  It's a free application that's gaining opularity with both Mac and Windows users.\n\nGizmo:  http://www.gizmoproject.com/\nSkype:  http://www.skype.com/intl/en-gb/

If you're lucky, you can use the IMAP, POP3 and NNTP functions, specifically imap_listscan. If not, you have some coding ahead of you, using socket and network functions.\n\nVisit http://www.php.net/docs.php and choose your language for documentation.

Maybe. The Best way to use this is with 'Mac Address Filtering', then nobody can access your network!

USE YAHOO MESSENGER OR MSN MESSENGER, OR YOU CAN USE WINDOWS MEDIA ENCODER, AND GIVE YOUR IP ADRESS TO YOUR FRIENDS

Most if not all programs support this. Though I use Trillian, I can talk to everyone on my buddy list, only 4 or others use that program. Not all features mesh, however... So file transfers, smiley's, and profiles sometimes get a little messy... Simple IMing should work fine, however.

Don't use the 'Forward' button.\n\nUse the 'Reply' button and then overtype the address with the address you want to send it to.\n\n///
