Here's the script I use for virtual hosts.  Make sure your kernel either
supports ip_alias, or you have built ip_alias.o.  I wrote it, and hereby
give whoever feels like using it, permission to do so.

#!/bin/bash

names="host1 host2 host3 host4"

count=0

if [ "$1" = "stop" ]; then
  for addr in $names
  do
	/sbin/route del $addr
	/sbin/ifconfig eth0:$count- $addr
	let count=$count+1
  done
elif [ "$1" = "start" -o "$1" = "" ]; then
  for addr in $names
  do
	/sbin/ifconfig eth0:$count $addr
	/sbin/route add -host $addr dev eth0:$count
	let count=$count+1
  done
else
  echo 'Usage: '$0' [start|stop]'
fi
