PCWorld is at war with itself over Linux on the Desktop...

So the story all starts with a very misguided reporter,  Tony Bradley,  failed to give Linux a chance to grow and change.  So much so that he declared it dead on the desktop.  He tried linux as his primary machine for 30 days.  Sounds like a good trial?  Well maybe it was but that was almost 2 years ago.  In the last two years for example Unity came from Shuttleworth's dreams to reality.  OpenOffice forked and LibreOffice has seen development explode. In general the world of Linux marches on and at an impressive pace.  Microsoft and Apple have been around for since the 1970's which makes them a little more than 30 years old.  As everyone will remember Linux just turned 20 last summer/fall.  So all things considered it's amazing how far it's come with no major financial backers.  You can read my own account of my life with Linux.  Oh yeah I am still using it as my main OS and using Windows 7 as little as possible.  I have found the latest versions of LibreOffice function nearly flawlessly and transparently with their Windows counterparts.  I digress though because this is supposed to be about the fact that even his fellow reporters at PCWorld don't agree.  This where things get interesting.

Katherine Noyes wrote a rebuttal that pretty much attacked Bradley for saying Linux only makes up 1% of the desktop market.  She goes on to rant amazingly for Linux on the desktop is not dead yet.  She makes some great points and finished by agreeing with us on the fact that while Tablets are here we certainly not seeing the end of the PC era as lots of people would like us to believe.

Bradley can’t seem to just let this die and write another even more insulting response.  He goes off again about how few people are using Linux on the desktop.  He is of course forgetting that Linux is only sold, the numbers he is using, on about 30-40 models of PC’s.  Most of those are from Linux Speciality builders not the mainstream builders.  This isn’t to say none of them are the big builders, except Apple of course, all have a few PC’s you can buy with Linux.  What he is missing is people like me and many friends of mine who are repurposing old PC’s as Linux machines.  I know of a few companies that are also doing this for Kiosks, Point of Sale/Service Machines, School terminal servers and Terminal emulators.  So while Linux may not be a contender yet they are moving in and picking off the low hanging fruit.  So like the improvements we have seen in the interface and easy of install the number of users is growing fast.

At this point I thought the story would be over.  Then the Mayor of Munich came out last week and gave an interview about how easy, fast and cheaply they have managed to switch over to their own custom version of Linux called LiMux.  Even with them spinning their own version, standing up a development environment, hiring staff to do all of this, they still will save 4 Million Euros in the switch.  Then an additional 2.8 Million Euros each year in lowered/eliminated license fees.  Then there is the fact that helpdesk calls complaining about the change dropped from 70 a month to just 46 as the number of PC’s running LiMux increased from 1,500 to 9500.  It’s stories like these that will make CEO’s and more likely CFO’s sit up and take notice.  This isn’t a small business, it’s not a simple environment, it’s a large cities entire infrastructure being converted to Linux.  What else comes close to a modern Enterprise.

So in conclusion, yes you should look to see if you could switch out some Windows machines with Linux.  The exercise and evaluation of whether it’s possible is relatively cheap, fast and low impact.  If you could save even 25% off your Windows related software fees wouldn’t it be worth it?

Does Desktop Linux Need a Steve Jobs?

What an interesting question.  Apple had Jobs and Windows had Gates.  Do we really need a persona like that to get linux on the desktop rolling?  Answering that question is the attempt of this article over at Datamation.com.  The concept seems to completely fly in the face of the community focus that the Open Source strives to be.  At the same time the kernel has Linus.  That one person who everyone knows and associates with it.  One of the big challenges we have with that is that there isn't only one desktop.  Gnome, KDE, XFCE and most recently Unity are some of the biggest.  But there are more.  So which team should be that person?  Let us know.

 

What do you think?

How do I get Xwindows to work when I am using an encrypted Drive?

My friend Mike Jansen pinged me this afternoon with an interesting problem.  

Here is the background:

He has setup a Linux VM and needs to get to it remotely from his PC running Windows.  He has xming(A great free XWindows server for Windows) and connects to the machine over SSH.  He decided he would take security to the next level and encrypted his personal directory.  Interesting fact is that when you do this on Ubuntu your home directory isn't decrypted or mounted until you actually login.  Why is that a problem?  Well as part of the login process SSH puts the magic-coookie XWindows needs to start into your /home/<UserID>/.Xauthority file.  The next thing that happens is that your encrypted directory is decrypted and mounted to /home/<UserID>/ which then hides /home/<UserID>/.Xauthority under the mount.  At that point it breaks X and stops you from running the XWindows Programs.  Unless you do something like what Mike pieced together.  What Mike has below should work system wide for all users.  You should as with all scripts test this out on a non-production system first.

Here is what he gave back to be to post to for everyone:

So I got my issue with encrypted home and ssh/xauth figured out. The solution is actually simple once it's figured out :)

The basic idea for xauth transfer was from http://froebe.net/blog/2008/11/14/getting-xlib-putty-x11-proxy-wrong-authentication-protocol-attempted-i-have-the-answer/

SSHRC

The idea for this came from the man page for SSH. 

I got rid of ~/.ssh/rc and put this in /etc/ssh/sshrc:


if read proto cookie && [ -n "$DISPLAY" ]; then
if [ `echo $DISPLAY | cut -c1-10` = 'localhost:' ]; then
# X11UseLocalhost=yes
echo add unix:`echo $DISPLAY | cut -c11-` $proto $cookie
else
# X11UseLocalhost=no
echo add $DISPLAY $proto $cookie
fi | xauth -q -
MYXAUTH=/home/.ecryptfs/`id -un`/.xauth
xauth list > $MYXAUTH
chmod go-r $MYXAUTH
fi

Mount encrypted home

The idea's behind this section came from this page http://ubuntuforums.org/showpost.php?p=8452729&postcount=7

In /etc/profile, I mount encrypted home (if it's not already mounted):


if test -e $HOME/.ecryptfs/auto-mount; then
mount | grep "$HOME type ecryptfs"
if test $? != 0; then
ecryptfs-mount-private
fi
fi

BASHRC


I got rid of ~/.bash_login and put this in /etc/bash.bashrc:


# Load xauth information from pre-encrypt mounting ssh initialiation
MYXAUTH=/home/.ecryptfs/`id -un`/.xauth
if [ -e "$MYXAUTH" ]; then
xauth add `cat $MYXAUTH`
rm $MYXAUTH
fi

Sample SSH LOGIN after Implementation



Here's what my ssh login looks like now (I have a bunch of outputs to understand the flow and make sure my real and effective uid's are what I expect):


Using username "mike-jansen".

Microsoft isn't really afraid of Linux

According to their latest fillings with the SEC Microsoft claims that Linux is no longer a threat on the desktop.  This story over at Business Insider tries to make more of it than it really is. I personally love seeing Linux getting the Apple treatment.  After playing with PinguyOS for the last couple of weeks I am starting to change my opinion on Desktop Linux.  I am running Windows apps in VMWare just like I have always done with Linux when I am forced to use Windows.  While there are only a few things I need to do in Windows I still can't live without it at work.  So let Microsoft and others keep thinking that Linux can't do the desktop.  Remember they thought the Internet was a FAD also.
