decide to start, what is the MAC-address .Roughly speaking, this network card identification number that uniquely distinguish it from the other cards of similar architecture.However, it is worth remembering that not all network protocols used MAC-address and not everywhere need global uniqueness of those addresses.For example, the LAN address must be unique, but within the framework of the Internet address may povtoritsya.Uznat its poppy possible through the use of console commands.
method call in each console its own operating system.For Windows Xp - is the "Start" - "Run» - «cmd», for Linux are commonly used shortcut keys Ctrl + Alt + F1 or Ctrl + Alt + F2, etc.(up to Ctrl + Alt + F6).
To learn MAC-address o
f the network device, use the following commands:
Windows - ipconfig / all - more detail paints - a MAC-address to which the network interface belongs.
For Linux is a command line you must fill the following code - ifconfig -a | grep HWaddr.
Mac OS X - ifconfig, or in System Settings & gt;Network & gt;select a connection & gt;Advanced & gt;Ethernet & gt;ID Ethernet.
is believed that MAC-address tightly "sewn" in the scheme of the network card and change the software in any way you can not.This statement is only partly true, becauseit holds only for systems with high requirements to the level of security, such as telecommunications.
In other cases, the address is easily changed by software.This is possible because the value specified by the driver, is more important than in the wired board.
To change the mac-address in Windows, do the following.
Walk at the "Start" - "Control Panel" - "Network Connections" - to select the desired connection - right-click - "Properties" - "Set" - "Advanced" tab.The list of properties
looking option Network Address.
In the field "Value" enter the desired value.
Fixed address can be verified using the command ipconfig / all.
In Linux poppy address changes with the following command from the user root:
# ifconfig ethN hw ether
where ethN - the name of the network interface.
