====== Set Static IP on RedHat ======
  * # check the connected interface - usually eth0 but could be eth1, this affects what file we want to edit
  * ifconfig
  * # backup the config file of that interface 
  * sudo cp /etc/sysconfig/network-scripts/ifcfg-eth0 /home/scotty/backup/ifcfg-eth0.backup
  * # A Config File without a static IP will look like :
