Routing in Linux

Check that TCP/IP networking is installed properly by trying to ping 127.0.0.1, then check that ipchains is installed by typing "ipchains -L" (note: the machine set up as a router for this article used a Server install of RedHat 6.2, and all networking services were installed and set up properly by the installation program)
