Greetings,
I run a K12LTSP network in my English class. I regularly get old computers donated to the class but I've had trouble getting them to play nice on the network. I did full linux installs on the soon-to-be clients and set X -query 192.168.0.254 in the .bash_profile to call on the main server to access the network.

A student recently installed DSL .9.1 on a beater box PII in under 15 minutes! I was thrilled! Here it was! A way to squeeze more life out of throw away machines as clients on an LTSP network... but after much fiddling we couldn't get the DSL to call 192.168.0.254 without gettin errors of /tmp/X.11xxx does not exist or is suspicious. And file 1777 is not correct (forgive the garbled error message, I'm not sitting in front of the error message now).

Long story short, there are thousands of old PI and PIIs that could be recycled into a K12LTSP network if I(we) can sort out how to get DSL to play nice on a network using an X -query.

I know that Africa and S. America are using k12ltsp in a big way... getting DSL to act as the client bridge could really significantly expand old computer usage!

You can read more about other client installs to make it easier to build K12LTSP networks here:

Any tips on the X -query problem are most welcome!

best!
Dennis

Just a thought..

If you find this works for you,
we can easily make a remaster to include this for you automatically...
remember, this is only a test. A real version would be seamless.

After booting up DSL, grab the dsl-dpkg.dsl extension, and the
XFree86.dsl extension. They are in the repository..

http://www.ibiblio.org/pub....pkg.dsl
http://www.ibiblio.org/pub....e86.dsl

Installing the dsl-dpkg.dsl file is easy.. Open up emelfm, your file manager ,
highlight the dsl-dpkg.dsl file, and click the myDSL button at the top center of emelfm. ( alternate - from shell prompt - type ' mydsl-load dsl-dpkg.dsl ' )

This will install the dpkg files, and make your system writable.

Basically, for this test, we can install the Xfree86.dsl like any other extension
open emelfm , the file manager, highlight the file, and click the myDSL button .
( alternate - from shell prompt - cd to /home/dsl,
and type ' mydsl-load xfree86.dsl ' )

This Xserver will respond to the X -query request.
It works for me here anyway, without an LTSP server available.

There are some instructions for setup in the xfree86.dsl.info file,
found in the same place where you obtained the extension.

Here's a walkthrough for the instructions for Xfree86..

Now that they are installed , go into your /home/dsl directory,

Look in the Xfree86_config_files directory, and copy the file for vesa support
to a file named /etc/X11/XF86Config-4

Next, grab the file called .xserverrc_for _xfree86 , and copy it to a file
called /home/dsl/.xserverrc ( it will overwrite - it's OK )
( you will need to click on the "H" to see hidden files in emelfm )

Next, exit X by using ctrl-atl-bksp .
At anytime, you can type startx to see if your X desktop works.. it should.

At the prompt, type this.
XFree86 -query 192.168.0.254

The xserver should respond to the request..

If you see the /tmp/.X11-unix issue, the command
' chown root.root /tmp/.X11-unix ' seems to work for me.

Let us know if this works for you.

If at anytime, you want the XKdrive server back, simply exit X,
and at the prompt, type xsetup.sh to reselect your xkdrive options.
then running startx at the prompt will put you back where you started.

Hello DSL team ; any chance xfree86 would be a feature in future releases , I have collected a few pent 1 and would like to take them to El Salvador and set-up an LTSP network with some sort of back-up distro on every machine in case the network fails and DSL is ideal because of its size I'll apreciate your response .

No chance.

XFree86 uses up too much disk space because the #1 rule of DSL is that the livecd must be 50MB in size or smaller in order to fit on a business card sized CD-R.

You can always install the *.dsl file, though.

I tried the tips on the first reply post to the dot but I was unsuccesful so I decided to try apt-get for fun and followed it as if I was installing the xwindows system for first time and it worked now I can log unto my ltsp server with an X -broadcast
I am pretty happy about this
Thanks DSL
