Connecting the server


I have four unix-type servers in the network , they all have different application and in the same subnet and have static IP address eg. the IP address is 192.168.0.1 , 192.168.0.2 , 192.168.0.3 , 192.168.0.4 . Now , if I want to make all these servers can have fail-over function to make sure to can connect to the network , is it possible ? for example , a user want to connect 192.168.0.1 , if this server is corrupted suddenly , then the user will automatically login another server 192.168.0.2 , if this server is corrupted also , then switch to another server , of course they have the same password in all these servers, is this possible ? how to make it ? thx in advance.

There is software called heartbeat to do this..

It uses a virtual ip address, eg 192.168.0.10 and a virtual MAC address
The servers can take it in turns to have this ip address & MAC depending on load, link status etc
