I'm trying to setup a LVS cluster using ipvs, heartbeat and ldirectord
with a LVS-Tun architecture. I'm not using the configure scripts, but I
am consulting them for setup reference. Here is my question:
in the rc.lvs_tun script generated, the interface hiding seems to be
done twice. First like this:
$ECHO 1 > /proc/sys/net/ipv4/conf/all/hidden
Then this:
$ECHO 1 > /proc/sys/net/ipv4/conf/${SHORT_DEV}/hidden
I understand the second line, but wouldn't the first one make the entire
machine invisible (i.e. never responding to any ARP requests on any
interface and could never be connected to)? Won't the RIP not be
accessible?
I've read about the whole ARP problem, but I'm still confused about this
a little bit.
This is running on Linux realservers, of course, with kernel 2.4.6-xfs
and the hidden patch.
For my own bootup scripts, do I need the first line?
Thanks for any insight anyone has on this.
