This section describes the design of the Dachstein distributions, as well as the Linux operating system they create after booting. This knowledge is essential for a good understanding of how to configure and modify the firewall.
Notice, that there is more than 1.44 Mb of information on the disk. That is because this disk is formatted to 1.68 Mb (using the same format as the Microsoft .CAB file disk). Notice also, that even though we are dealing with the Linux operating system, the format of the Dachstein floppy disk appears to be in MS-DOS format. This means that you can use Microsoft Windows to add and delete files to and from the disk, as well as modify the SYSLINUX.CFG file.
On the disk, there are the following files: <anyfile>.LRP (files ending in .LRP are packages that load into Linux after the Linux kernel boots up), LINUX (the kernel), SYSLINUX.CFG (the disk configuration file), SYSLINUX.DPY (the firewall boot-up screen), and readme.txt. Of particular interest to you is the SYSLINUX.CFG file. This file dictates which packages get loaded when the system is booted. Depending upon which application you use to edit this file, its text may appear on one line, or up to 6 lines. If you locate the part of this file that begins with LRP=, you will see the names of packages which load at boot time. You can insert, or delete different package entries from this line to make certain packages load, or keep others from loading. The thing to remember is that there should be no spaces in between the commas and package names, and that the package names are identical to the file names, without the ".LRP".
