It handles your virtual IP and the ARP caching issues associated with it (by means of a GARP packet).

<div>i have two linux machines, that are running on the same LAN.</div>
<div>i would like to find a way to set HA IP.</div>
<div>i was thinking on creating virtual ip that will ride on the exiting eth. lets say 10.0.0.1 and 10.0.0.2 and the VIP will be 172.16.4.1</div>
<div>both will run an infinite loop of:while (ping 172.16.4.1) do ...</div>
<div>once that the while is exiting in one of the hosts it will try to acquire the VIP. </div>
<div>there is additional lock mechanism to implement so the two servers will not try to acquire the same VIP concurrently.</div>
<div> </div>
<div>i would like to know if there is any out of the box sofware that can do this task?</div>
