View source for Setup linux test client


Linux Test setup, it has been tested on

*Debian 8
*Apache 2.4
*Hostname used for the test: myLVS-LinuxClient

=System settings to configure the loop back adapter=

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<br>

The new myLVS overview should now show the disabled server marked with a red cross:<br>

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)<br>
There should be the Linux/Debian default web page<br>
