fli4l (flexible internet router for linux, before floppy isdn for linux) is a Linux distribution, actively developed by German developers since 2000. The projects main task is to provide a small Linux system that turns almost every machine into a router. The distribution can run from a floppy disk and was created with the aim of simple configuration and support for older hardware.
Characteristics and requirements
The hardware requirements for fli4l are low, a 486 with 16 MiB RAM and (depending upon the configuration) one or two network interface controllers is quite adequate. A hard disk drive is not required, but can be used by fli4l too.
Newer versions of fli4l provide also the possibility to create a working installation on a CF card in a card reader, which card then in turn can operate from a CF adapter in an IDE slot. Also the generation of an ISO image is supported to run from a CD-ROM as well as from DOC/DOM for Embedded systems.
There are two development branches for fli4l, a stable and a development version.
The present stable release is based on a 2.6 kernel and contains virtualization by means of Xen. USB and Wireless LAN are supported to a great extent as well as current embedded hardware as ALIX, Soekris and EPIA series.
The development version uses a 3.x.y kernel.
fli4l is a modular system using so-called OPT-packages. To create an individual configuration, only software packages for those options, that are needed, are downloaded and unzipped into the directory tree. To extend the basic functionality, a wide range of applications is available in the so-called OPT-database; for example, optional packages can be used for monitoring traffic or an fli4l can function as a printserver. This process easily allows own developments, that can be made available to other users via the OPT-database.
An fli4l router can be controlled and monitored with a browser-based interface. Besides, the program imonc (isdn monitor client) is available for Windows and Linux (GTK). imonc allows extensive control as well as remote-controlled update of the router's software.
