Setting up Basic Networking

Here will be set up basic networking now that all the necessary software has been installed. There isn't all that much to do, really, just creating a basic /etc/hosts file, and downloading some high-quality network information files.

The first step is to create /etc/hosts. This file contains information allowing resolution of host names to IP addresses. Create a very basic one (we'll make a better one later) with the following command:

echo "127.0.0.1 $(hostname) localhost" > /etc/hosts

Now unpack the Lfs-Utils tarball again, as we're going to copy two necessary files from it. One is /etc/services, which is used to resolve service numbers to human-readable names, and the other is /etc/protocols, which does the same for protocol numbers. Copy them with the following command after you have entered the Lfs-Utils directory:

cp -f etc/{services,protocols} /etc
