5 How can I make multiple virtual IP-numbers?

On a Linux machine

       For multiple IP numbers the Linux aproach which works best is with the dummy interface.
       First you recompile a recent kernel, including the possibiliy of modules. In the kernel, do not
       include the dummy interface. Next you do a "make modules", and a "make
       install-modules". After you have rebooted you can add extra ip numbers by doing (you can
       also add this to your /etc/rc.d/rc.local): 

       # Add dummy modules
       ######################################
       /sbin/insmod -o dummy0 ./dummy.o
       /sbin/insmod -o dummy1 ./dummy.o

       # Add interface params, route arp addr
       ######################################
       /sbin/ifconfig dummy0 www.click.es up
       /sbin/route add www.click.es dummy0
       /sbin/arp -s www.click.es 00:20:A9:0B:49:D5 pub

       /sbin/ifconfig dummy1 www.ibercaja.es up
       /sbin/route add www.ibercaja.es dummy1
       /sbin/arp -s www.ibercaja.es 00:20:A9:0B:49:D5 pub

       Note that the hardware address is YOUR ethernet hardware address. You can get it from
       the ifconfig eth0 output.
