I would like to thank Brad Hards, the primary author of the Linux CDCEther kernel driver for graciously volunteering several useful bits of information.
Also, I would like to thank Marla, who has cheerily tolerated the time I've spent sifting through documentation and endless typing while completing this and other projects. Without you I'm lost.

If you have an earlier (e.g., 3000 series) or later (e.g. 5000) series Surfboard and have it working in linux, please contact me with any model-specific setup information so we can update this document!
The following conventions are used in this document and are outlined here for those who may not yet have a complete understanding of how to access and control the underlying operating system in Linux, which is almost always the bash shell.
First, filenames are referenced in a paragraph like so: /path/file
Commands in Linux are executed (or 'called') at the command prompt, otherwise known as the 'command line.' If you are in the non-graphical (text-based) environment you will usually be presented the bash shell prompt which is a dollar sign:
...or the hash mark:
...if you have logged in as root or have acquired root, or 'superuser' privileges. You can also access the bash shell in the X window system, otherwise known as X or X11, with an xterm or similar X-terminal-emulator. Commands to be performed at the bash prompt, but referenced in a paragraph of this document, usually look like this: do this now
Commands and/or the resulting output of commands may also be outlined with screen output in their own paragraph or heading:
$ date Sun Jul 27 22:37:11 CDT 2003
When a command is written in front of the bash prompt (e.g. $ date above), it is assumed the [Return] or [Enter] key has been depressed after the command, possibly followed by the output on a new line (e.g., as in the date in the above example).
