Dear All,

I have one doubt about mac binding. i want to bind two ip address to one mac address. Is it possible or not?
If it is possible explain me how to do.

I am using centos release 4.1 server.Actually my end user uses two systems. the ip address has to be used only in the coresponding mac address of two systems.

Is there any software used.

Please respond my questions.

mac is hardware ip is the internet provider address hardware connects to one at a time. through a gateway so disconnect from one then connect to the other this issue has been around for a long time. how about this two wifi cards both connected to two different IP's.
The problem is your localhost is your ifconfig lo can only use one at a time on the loop back.
there you go. One peace of hardware talking to one peace of hardware

I'm not sure whether I get your problem right, but if you simply want two ip adresses on one physical device you should setup an ip alias. See http://www.faqs.org/docs/Linux-mini/IP-Alias.html about how to do that. If you use some kind of management software (webmin or a graphical interface of some sort) it might be even easier.
