3. Base configuration

Since fli4l 2.0 the distribution is designed to be modular and consists of multiple packages which have to be downloaded separately. The package fli4l-3.10.17.tar.gz contains only the base software for a pure ethernet router. For DSL, ISDN, and other software you will have to download further packages and extract them into the directory fli4l-3.10.17/. In order to allow free choice of the fli4l's linux system kernel, the kernel has been removed from the base package and was put into an own package. This implies that at least both the base and kernel packages are required. Table 3.1 gives an overview of additional software packages.

The files necessary for configuring the fli4l router are placed in the directory config/. They are described later in this chapter.

These files can be edited with a simple text editor, or alternatively with an editor specially designed for fli4l. Miscellaneous editors can be found under

If you need to adapt/extend the fli4l system in addition to the possible settings described below, you will need a working Linux system in order to adjust the RootFS. The file src/README will provide you with more information.
