802.11N Support in Freebsd (For the Run(4) Driver)
802.11n support in FreeBSD (for the run(4) driver) 15412 F’19 1 / 15 Motivation ● “Do something with operating systems” – OS Junkie: Ubuntu → Fedora → Arch Linux → Gentoo → FreeBSD ● Do something for the community – So much free (not free as in free beer) software out there for use – Time to give something back! ● Faster WiFi doesn’t hurt – Makes FreeBSD more usable ● Less angry users: “But this works on Lunix!” 2 / 15 FreeBSD ● Open source, UNIX ● Official webpage: freebsd.org ● Large, helpful community – IRC Channels on Freenode (#freebsd) – Forums (forums.freebsd.org) – Mailing lists (lists.freebsd.org) ● Latest Release: FreeBSD 12 (2018) 3 / 15 802.11 ● IEEE 802.11: Standard for WiFi – 802.11b: 2.4GHz, Max rate 11 Mbps, range 150 ft., Year 1999 – 802.11g: 2.4 GHz, Max rate 54 Mbps, range 150 ft., Year 2003 – 802.11n: 2.4GHz or 5 GHz, Max rate 300 Mbps (single antenna), 450 Mbps (MIMO), range 175 ft., Year 2009 4 / 15 Ralink ● Produces WiFi chips – See https://wikidevi.com/wiki/Ralink for list of chips ● Linux driver: rt2800usb (USB Ralink 802.11n devices) ( https://wiki.debian.org/rt2800usb). ● FreeBSD driver: run (see https://www.freebsd.org/cgi/man.cgi?run(4) ) – Caveats : “The run driver does not support any of the 802.11n capabilities offered by the RT2800, RT3000 and RT3900 chipsets.“ 5 / 15 Existing code base ● The run driver supports several chipsets and adapters (such as ASUS USB N-66) but without support for 802.11n – This means reduced speeds – This means it will misbehave when you turn on your microwave ● run(4) also has annoying ‘device timeout’ errors where the card stops responding. -

The Development of Unix
The development of Unix ∗ By Kasper Edwards Departmnent of Technology and Social Sciences, Technical University of Denmark Building 303 East, room 150, 2800 Lyngby, Denmark. (email: [email protected]) ABSTRACT This paper tells the story of the development of the Unix time sharing system. The development at AT&T and the MULTICS roots are uncovered. The events are presented in chronological order from 1969 to 1995. The Berkeley Software Distribution (BSD) are presented as well as the Free Software Foundation and other. Note: This is a working paper. Short sections of text, no more than two paragraphs may be quoted without permission provided that full credit is given to the source. Copyright © 2000-2001 by Kasper Edwards, all rights reserved. Comments are welcome to [email protected]. ∗ I would like to thank Keld Jørn Simmonsen, Ass. Prof. Jørgen Lindgaard Pedersen of the Technical University of Denmark and Ass. Prof. Jørgen Steensgaard for helpful comments and suggestions on earlier drafts on this paper. I assume full responsibility for any remaining vulnerabilities. Page 1 of 31 1.1 Introduction This thesis about Linux, however Linux is called a Unix clone in the sense that it looks like, and are designed on the same principles as Unix. Both Unix and Linux are POSIX (Portable Operating System Interface) compliant (described in paragraph 3.29). In short POSIX describes the Unix user interface, i.e. commands and their syntax. Some Unix’es are certified POSIX compliant but no one have yet been willing to pay a third party company to test the POSIX compliance of Linux. -

Jargon File, Version 4.0.0, 24 Jul 1996
JARGON FILE, VERSION 4.0.0, 24 JUL 1996 This is the Jargon File, a comprehensive compendium of hacker slang illuminating many aspects of hackish tradition, folklore, and humor. This document (the Jargon File) is in the public domain, to be freely used, shared, and modified. There are (by intention) no legal restraints on what you can do with it, but there are traditions about its proper use to which many hackers are quite strongly attached. Please extend the courtesy of proper citation when you quote the File, ideally with a version number, as it will change and grow over time. (Examples of appropriate citation form: "Jargon File 4.0.0" or "The on-line hacker Jargon File, version 4.0.0, 24 JUL 1996".) The Jargon File is a common heritage of the hacker culture. Over the years a number of individuals have volunteered considerable time to maintaining the File and been recognized by the net at large as editors of it. Editorial responsibilities include: to collate contributions and suggestions from others; to seek out corroborating information; to cross-reference related entries; to keep the file in a consistent format; and to announce and distribute updated versions periodically. Current volunteer editors include: Eric Raymond [email protected] Although there is no requirement that you do so, it is considered good form to check with an editor before quoting the File in a published work or commercial product. We may have additional information that would be helpful to you and can assist you in framing your quote to reflect not only the letter of the File but its spirit as well. -
