* In this lab, you will learn the basics of networking by using your Virtual Machines and your c6host '''c7host''' machine.  * You will first set up a virtual private network among your c7host machine at your Virtual Machines. In addition, you will learn to set up '''network names''' (to associate with server's IP Addresses), '''associate network services with port numbers''' for troubleshooting purposes, and learn how to backup files by date/timesetup '''firewall policies''' via the '''iptables''' command.

# Use the CemtOS CentOS GUI program to configure network interfaces with static IP configuration and host name resolution# Use the <code>'''find</code> ''' command to locate the configuration files modified by the GUI network configuration program# To examine some of the Linux's TCP/IP configuration files in the <code>/etc/</code> directory# To configure a CentOS host VM with static network configuration without a GUI tool# To backup more recent files via the '''find''' command and a date/time-stamp file.# To configure the linux firewall <code>'''iptables</code> ''' to allow/disallow/forward different types of network traffic using simple rules
