System settings to configure the loop back adapter
To make the change permanent you may edit /etc/sysctl.conf and add:
net.ipv4.conf.eth0.arp_ignore = 1 net.ipv4.conf.eth0.arp_announce = 2 net.ipv4.conf.all.arp_ignore = 1 net.ipv4.conf.all.arp_announce = 2
To make it apllied immediatly you can set:
root@myLVS-LinuxClient:~# echo "1" > /proc/sys/net/ipv4/conf/eth0/arp_ignore root@myLVS-LinuxClient:~# echo "2" > /proc/sys/net/ipv4/conf/eth0/arp_announce root@myLVS-LinuxClient:~# echo "1" > /proc/sys/net/ipv4/conf/all/arp_ignore root@myLVS-LinuxClient:~# echo "2" > /proc/sys/net/ipv4/conf/all/arp_announce
Add to /etc/rc.local to automatic load the loop back adapter:
/sbin/ifconfig lo:0 192.168.2.220 -arp netmask 255.255.255.255 up
ifconfig should look like:
root@myLVS-LinuxClient:~# ifconfig

Testing the loop back adapter
Switch off the first (Windows) client to make Linux as the only web server
The new myLVS overview should now show the disabled (Windows) server marked with a red cross:
Use a network client and open the URL http://192.168.2.220, we should now see the result of web02 (because web01 is off)
There should be the Linux/Debian default web page
