Zdravei The hardware address of a network card (also known as mac address, ethernet address) is usually burned into the *ROM of the netword card. Some of the new cards (especially those built into the motherboard) allow one to change the value of the hardware address.
For all practical purposes, the need to change the hardware addres can be addressed at a purely software level because the network card (usually) by itself does not perform any function involving the hardware address.. (i.e. it doesnt send anything over the wire by itself) The software responsible for handling the bits coming in through the wire can be fiddled around with to change the hardware address easily. (under linux, one can use ifconfig) Some of the interesting things one can do: (listing only one :-) ) * Listen on multiple hardware addresses at the same time.. that is one machine can be made to appear as n machines.. (no.. I am not talking about multiple IP Addresses) If there is still confusion regarding hardware address, think about where is it used (and why) and where are the packets constructed and all... _______________________________________________ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd
