  • 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.

  • Unix Command Line; Editors
    Unix command line; editors Karl Broman Biostatistics & Medical Informatics, UW–Madison kbroman.org github.com/kbroman @kwbroman Course web: kbroman.org/AdvData My goal in this lecture is to convince you that (a) command-line-based tools are the things to focus on, (b) you need to choose a powerful, universal text editor (you’ll use it a lot), (c) you want to be comfortable and skilled with each. For your work to be reproducible, it needs to be code-based; don’t touch that mouse! Windows vs. Mac OSX vs. Linux Remote vs. Not 2 The Windows operating system is not very programmer-friendly. Mac OSX isn’t either, but under the hood, it’s just unix. Don’t touch the mouse! Open a terminal window and start typing. I do most of my work directly on my desktop or laptop. You might prefer to work remotely on a server, instead. But I can’t stand having any lag in looking at graphics. If you use Windows... Consider Git Bash (or Cygwin) or turn on the Windows subsystem for linux 3 Cygwin is an effort to get Unix command-line tools in Windows. Git Bash combines git (for version control) and bash (the unix shell); it’s simpler to deal with than Cygwin. Linux is now accessible in Windows 10, but you have to enable it. If you use a Mac... Consider Homebrew and iTerm2 Also the XCode command line tools 4 Homebrew is a packaging system; iTerm2 is a Terminal replacement. The XCode command line tools are a must for most unixy things on a Mac.

  • Introduction to Cron - Goals
    Introduction to cron - Goals • Goals: – Understand how cron works – Understand crontab files – Understand our conventions 1 What is cron? • cron is a Unix daemon program • cron automatically runs programs at given times • cron is different from at, which is a queued batch job facility • We are moving to use cron for batch jobs, as opposed to at 2 Crontab files (Part 1) • Each user on each machine has a crontab file. • So, ecogdev has its own file on each of sid & soltrane, as does ecogdba. • This file consists of lines that look like this: 15 03 * * * /ecog/ecogdev/src/reports/timezone/timezoneauto 15 03 * * 0 /ecog/ecogdev/src/reports/swog_prots/swog_protsauto 30 0 * * * /ecog/ecogdev/bin/ftpschema 3 Crontab Files (Part 2) • Here is one line from a crontab file: 30 0 * * * /ecog/ecogdev/bin/ftpschema • Six fields on this line (* is a wildcard): – 1. Minute of the hour (0-59) – 2. Hour of the day (0-23) – 3. Day of the month (0-31) – 4. Month of the year (1-12) – 5. Day of the week (0-6 with 0=Sunday) – 6. Command line • Quiz: When does this job run? 4 Crontab Files (Part 3) • Here is that crontab line again: 30 0 * * * /ecog/ecogdev/bin/ftpschema • The rightmost field is the command line • Best to use absolute paths, as in this entry • Commands can be executable programs or shell scripts • Put #!/bin/csh at top of C Shell scripts 5 The crontab command • The crontab command allows you to install and edit per-user crontab files. • These are the installed crontab files.
