Gratuitous ARP

[Mikkel Kruse Johnsen <mkj.its@xxxxxx>]

Hi

I have a cluster using LVS and keepalived running using DR. But I really hade to patch my kernel with the hidden path. I found the "garp" at http://www.linuxvirtualserver.org/~acassen/ and thought it could do the trick.

Is it possible to just run this script on the real servers and that should be it.

Is there a risk off failure,  the eth0:0 will be up before the Gratuitous ARP is send, will it make chaos in that spilt second that it comes up before a Gratuitous ARP is set on the interface ?

Is this tool doing what I think it does, prevent the eth0:0 to responde to ARP's ?

------
#!/bin/sh
ifconfig eth0:0 130.226.47.163 netmask 255.255.255.255 broadcast 130.226.47.163 up
route add -host 130.226.47.163 dev eth0:0
./garp -i eth0:0 -a 130.226.47.163
-------
                                                                                                                                  

Bye
