Users, Iam working in a LAN with a number of systems. A system has X hardware address and another has Y hardware address. I want to set the hardware address of the second system also to X. I also want to set the primary IP addresses of both systems to 172.31.19.30. So when I ping to 172.31.19.30, both the systems should respond. The topology of LAN we are using is star. All systems are connected to a Switch. Does the settings change when we are using a bus topology? Do I have to write a start up script? How should I write? My actual goal is to start 2 web servers on two systems with same hardware address and same primary IP address but with different secondary IP addresses. So when a request comes from a client, the request has to be seen by both systems. I will write some mechanism by which only one will respond finally. Please help! Thanks in advance, ravikumar __________________________________ Do you Yahoo!? Yahoo!
