This section is provided for the non-Linux user. It gives a brief overview of the concepts and actions necessary to get around in the Dachstein firewall. Note that this is not by any means a comprehensive 'Getting Started with Linux' tutorial, nor will it help much with a full Linux distribution such as RedHat, Debian, or Slackware. It simply gives you some of the commands and concepts to get through the Dachstein installation and configuration. For more in-depth resources on Linux and networking, see Appendix B, Resources.

The Lrcfg Script

Once Dachstein boots, you will be at the main menu for the lrcfg program. This program automatically loads by default. It is a simple menu-driven user interface to backing up the firewall, and editing the various configuration files. Press a number or letter, then the [Enter] key to select the respective feature or function. This is a good time to check out the Dachstein readme file and the network.conf readme. They go into some detail in configuring Dachstein through the menu system. There really isn't much Linux knowledge required here in the menus. If you press the [q] key, then [Enter], now you are in the Linux space, and should read on.
