Create a very basic one (we'll make a better one later, but Perl needs it now for doing some tests) 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
