LinuxChix Los Angeles

Hello all Linux Chix!

First of all, just wanted to remind everyone that the SCALE 8x talks are available to listen to via mp3 downloads from the SCALE 8x Conference Schedule page:

http://www.socallinuxexpo.org/scale8x/conference-schedule-feb-19-2010

Make sure to listen to the WIOS talks with Amber Graner; Rikki Kite; Malakai Wade, Mirano Cafiero, & Saskia Wade Etc. Etc. and many of the other talks at SCALE 8x that you may have missed!  I have been enjoying listening to the talks that I went to a second time as well as those I missed

Second, last week was the Google I/O Developers Conference in San Francisco!  Some very important and exciting announcements about Android Frojo and Google TV where made.  Google gave out two Android smart phones, a Verizon Droid and the Sprint HTC Evo, to whoever attended the keynote speeches!  Make sure to watch Day 2 coverage of Google I/O 2010 on TWIT with Leo Laporte:

Third, I just discovered a wonderful new blog:

http://www.womenwithdroids.com/

In the Women With Droids WWD Profiles section Gina Trapani, Google developer and tech-guru, is highlighted!  Here is a wonderful interview with Gina that is linked from the Women With Droids site:

http://androidandme.com/2010/01/news/interviews/celebrity-android-user-gina-trapani/

I listen to the wonderfully talented and geeky Gina Trapani every week with Leo Leporte on the This Week in Google netcast.  A must listen for every Linux Chix:

And, of course, last week TWIG also covered Google I/O:

Either by Tux or by Droid, Linux Rules The World!

This recent inbox deposit got my attention.

• Subject: UPS Delivery Problem NR.6256171
• (Visible) Sender: Manager Rosella Edwards
• (Visible) Return email: manager@ups.com

 

There was also a not implausible message body considering that is right around the time that lots of Xmas presents get shipped off to various locations.

Hello! We were not able to deliver the package you have sent on the 1st of December in time because the recipient’s address is inexact. Please print out the invoice copy attached and collect the package at our department. /S/ United Parcel Service of America.

 

Of course it was sent to a public ‘info’ address which is not generally used. First Flag. It contained a .zip which I was instructed to open. Second Flag. And the IP where the email was originally sent (obtained from the view headers option in my email client) pointed to a location in Silesia. And Delete.

No. I didn’t open the attachment, which likely contained some variant of a Windows executable malware that wouldn’t have affected my lovely Ubuntu system. I wasn’t that curious, but I was impressed with social engineering involved in this particular bit of malware delivery.

Lesson? Don’t open zips from UPS reporting delivery problems. You’d be p0nwed!

UPDATE 9/15: Issue is gone (I hope!). Everything I wrote about fsockopen, cURL, etc. forget it. It was a server firewall issue. The reason for the ad hoc creation of dynamic rules which intermittently blocked outbound http requests is still under investigation, but the installation of a firewall that had better integration with the backend web administration interface looks to have helped.
UPDATE 9/13: Issue is back. All outside connections, including rss feeds, are out. Damn.

Hi Betty!, and to all those LinuxChix and LinuxGuys who need to recover files
or partitions off dead flash drives, usually fried by Windows, or any hard drive
or removable media

Here is the website for the TestDisk and PhotoRec software that
was used to recover your flash drive in Linux at our last LinuxChixLa meeting at
Philippes:

http://www.cgsecurity.org/wiki/Main_Page

It is also available for Windows and Mac OSX.

To install and run TestDisk and PhotoRec In Ubuntu Linux:

“sudo apt-get install testdisk” from a terminal and then run
“sudo testdisk” or “sudo photorec”
Both the photo recovery program and test disk are included in the
debian package.
The PhotoRec software is what was used to recover the files off your
dead flash drive.  It will recover many types of files, not just multimedia

The detailed instructions for running PhotoRec are demonstrated on the
PhotoRec main site:
http://www.cgsecurity.org/wiki/PhotoRec_Step_By_Step

TestDIsk/PhotoRec is usually faster at data recovery than Ddrescue, but
Ddrescue is more thorough and efficient:
http://www.gnu.org/software/ddrescue/ddrescue.html
Ddrescue and fdisk is what I always used to use until Chad gave us the heads-up
on TestDisk

Knoppix Linux Live CD has TestDisk/PhotoRec and Ddrescue already installed!
Here are the instructions for using these utilities in Knoppix:
http://www.cgsecurity.org/wiki/Damaged_Hard_Disk#Booting_from_Knoppix.2C_a_Linux_LiveCD

The Ubuntu Rescue Remix Live CD (http://ubuntu-rescue-remix.org/) is also a great option.  It includes TestDisk and Ddrescue as well.

And the Ultimate Boot CD (http://www.ultimatebootcd.com/), one of my favorite
boot cds, includes TestDisk as well.

Have fun recovering files

I ‘fess. I’m a packrat. I save everything. And since I’m ‘fessing things, I admit to not having a good system, well, ANY system, to archive digital files.

When I either change or upgrade my hardware I’ve copied my old home directories and saved them in their entirety as a archive folder in my new fresh clean home directory, and then move individual files up to work on them as needed. The plan was always to go back and systematically organize and consolidate the contents. Which never happened.

The folly of my packrat ways was highlighted when I made a backup of the files on my penultimate computer to an external usb harddrive in preparation to wipe and install a home server. Well, 5 hours and 25 GBs later the archived home directories from my last five computers finished the transfer.

So my external drive now contains the nested archived home directories from:
-> hardy.laptop
—> gutsy.laptop
—–> dapper.desktop
——-> redhat73.desktop
———> windows98.desktop

So I’ve learned that I have to Organize, Consolidate, and Delete: a.k.a. OCD

Wandering out on the web in search of apache python information and found a sweet site with some quick tips for all things *nix from nixCraft. I found what I needed on configuring Apache2 with mod_python (and you’ll be hearing all about it at our April 19th meeting), plus so much more. If the sampling below doesn’t inspire you to add the nixCraft FAQ to your RSS reader of choice, me and my minions are coming to your house and taking all your penguins away.

• Explain: php_self or $_SERVER['PHP_SELF'] Usage

What’s the connection? On behalf of Ada Lovelace Day LinuxChix Los Angeles is highlighting Terri Haber’s in-the-trenches-sysadmin presentation at linux.conf.au in Hobert, Tasmania. And Terri brought back a Tuz from linux.conf.au! And what’s a Tuz? In addition to being the mascot for linux.conf.au, Linus Torvald is replacing Tux with Tuz for the Linux kernel release 2.6.29 to highlight the plight of the endangered Tasmanian Devils whose population is plummeting in the wild due to a contagious facial tumor disease.

And yes, that is Terri watching Linus save shave the 27 year-old-beard of Bdale Garbee to benefit Save the Tasmanian Devil foundation. (Complete slide show of the shave.)

Now back to LinuxChix Los Angeles and our contribution to Ada Lovelace Day. Ada Lovelace Day is all about highlighting the contributions of women in technology. So why Terri? Because Terri did a most difficult thing, she contributed. Contributing is hard, being visible is hard, and Terri was visibly contributing when she shared what she knew at linux.conf.au. And in her contribution, Terri advanced women’s visibility in technology. So thanks Terri, thanks for visibly contributing.

Hello linuxChix and linuxDudes too! I can’t wait for SCALE! Yeeeaaaahhhhh!!!

Hope everyone had a wonderful holiday season and has a happy new year!

Since our last LinuxChix LA meeting I have been writing some info and tips on how to install linux on a flash drive and what portable apps can be installed on USB drives. I wanted to be as prepared as possible for this topic because we decided this is what we are going to demonstrate at our booth and I wanted to make sure that I wouldn’t forget any of my findings on this wonderful subject. Running linux and apps from flash drives is one of my favorite geeky things to do, and one I have been excited about since the introduction of USB technology. Anyways, here are the notes that I have written on this subject. If anyone finds them useful I would be happy to print out lots of copies for our LinuxChix SCALE booth for us to use or to hand out as flyers. Just thought I would run this past everyone and see what you thought

This is one of the best applications for installing Linux/BSD on a flash drive:
UNetbootin from http://unetbootin.sourceforge.net/
It installs in almost every Linux Distro and Windows and has
a very easy to use GUI!
Here is a list of some of the default Linux/BSD Distributions you
can automatically download and install:
-Arch Linux
-BackTrack
-Damn Small Linux
-Debian
-Elive
-Fedora
-FreeBSD
-FreeDOS
-Gentoo
-0penSUSE
-Puppy Linux
-Slax
-SliTaz
-Ubuntu, Kubuntu, Xubuntu
Etc. Etc. Etc.
And it doesn’t stop there! Using UNetbootin you can also install any Linux ISO
of your choice to a flash drive !!! That also includes floppy disk images
as well as your own custum kernel and initrd !!!
UNetbootin can also be used to install any distro to your hard drive as well
!

Qemu, Qemu Launcher GUI For Linux, Qemu Manager GUI For Windows, VirtualBox Virtual machine emulators are a great way to test that your flash drive linux Etc. distribution has been installed correctly!
Here is a sample of testing your flash drive in a linux console:
qemu -m 512 -hda /dev/sda [Or sdb Etc. Do not include the partition number of the drive, just the name! -m is for the amount of memory you would like to emulate. It could be -m 64 or -m256 Etc.]

Of course most modern Linux Live CD distros have there own applications for creating a bootable flash drive. Ubuntu, Puppy Linux, Damn Small Linux, Gentoo, PCLinuxOS are just to name a few.

Mk-boot-usb: a Script to Create Multiple-Bootable USB Keys
can be downloaded from:
http://people.ofset.org/~ckhung/p/mk-boot-usb/index.php

BootFlashDOS For Windows
Small utility that will format and make DOS bootable your USB Flash Stick.
http://wareseeker.com/System/bootflashdos-1.0.zip/403111

PeToUSB 3.0.0.7 For Windows
Application for formatting and making bootable, USB Flash Memory Drives and USB HardDisks.
http://wareseeker.com/System/petousb-3.0.0.7.zip/403112

HP bootable flash utility for Windows
http://www.thepcspy.com/read/bootable_usb_flash_drive

Go to http://distrowatch.com/ for all the latest linux distro ISOs !

QTParted for Linux is the best app for repartitioning and reformating
your USB device!:
http://qtparted.sourceforge.net/index.en.html

Keep all USB drives formated in FAT32 or FAT16. Many computers, including
the ASUS EeePCs, will only boot a USB Drive formatted in FAT. There are
exceptions to this rule though.

Bootable Flash Drive Linux Distros For The ASUS EeePC :

ubuntu eee–An Ubuntu Linux Distro of course!:
http://www.ubuntu-eee.com/index.php
You have to have at least a 4gig drive to install on the Eee.
Boots to a window manager enhanced with an EeePC
Desktop. Sweet !

Breeezy for the eee–A Puppy Linux Distro:
http://minipc.org/safepup/index.php?file=Breeezy%20for%20the%20eee.htm
This is one of my favorites! And it works great on the 2gig Surf !

#! CRUNCHBANG LINUX–A Lightweight Ubuntu Linux Distro that comes in
Standard Desktop Edition, Lite Edition and now CrunchEee Eee PC Edition:
http://crunchbanglinux.org/
This is also one of my favorites and it also works great on the 2gig
Surf . I am running an older Lite Edition on my Eee, but the new
CrunchEee already has the enhanced Eee PC Linux Kernel included so no
compiling and updating is needed and everything works out of the box !

Enjoy using open source apps and operating systems with yuor USB flash drives

Well, maybe love isn’t quite the right word. More like deal, as learning to deal with run levels.

When I moved over from Redhat to Debian I really missed chkconfig, a wonderful helper script that obviated the need to manually mess around with the symbolic links in the /etc/rc.* family tree.   Ah, but sysvconfig to the rescue.

As an example, while I have Apache installed on my laptop I prefer to run this service selectively on an as needed basis. I mean, I don’t necessary want to make a web server available on my laptop when sipping coffee at my local wifi spot.  While there are other options, like update-rc.d, sysvconfig is, IMHO, the easiest and most intuitive method to enable/disable local services.
