[GRASS-user] grass live CD for education

Hi all,

I am giving GRASS (and open source GIS) workshops every now and then. The next one is in a few weeks. The problem is, I have only windows machines available, and I have had bad experiences with badly installed CYGWIN and GRASS versions in the past. (I have to leave it to the sysadmins).

I have proposed to use linux liveCD's but I am not allowed to use them due to security reasons (access to the HD and network).

Theoretically it does not seem to be too difficult to disable those functions on a liveCD. Although I am an experienced linux user, I have no experience with liveCD's. So before I spend a lot of time trying, I would like the opinion of the mailing list.
Specifically:

- anyone with experience making linux live CD's including grass?

- if so, which distribution to start with (knoppix seems a logical choice and has a good customisation manual)

- any hidden snakes under the grass that anyone knows of?

Cheers

Wouter

There's

which you can combine with the DebianGIS repository:

Certainly, you could create a LiveCD which lacks support for hard
disks and network adapters (although you are going to be rather
limited in the amount of data you can handle if your filesystem has to
fit into RAM).

However, the issue may not be whether the LiveCD is actually safe, but
whether the admins *know* that it is safe, and are willing to make the
necessary changes to accomodate this (I would assume that the machines
are configured not to boot from removable media).

Hi Wouter,

At http://livecd.ominiverdi.org/ you can found more info about our GIS Livecd Project.

The latest stable is the "Desktop Edition 2007.0" with:

GRASS 6.2.1
QGIS 0.8
PostgreSQL 8.1.5
POSTGIS 1.14
GDAL 1.3.2
ecc...

There are also some sample data inside (as file and inside Postgis).

Currently we are working on the "Server Edition 2007.0" and on the "Desktop Edition 2007.1",
but we can't say when will be finished.

If need more info ( like a specific customization), let me know.

Bye

Luca

Dear Wouter,

About LiveCD with GRASS, I suggest to prove the POSEIDON linux distribution. This is Knoppix modified which contain a lot of software for GIS as GRASS, QGIS, SPRING, and other more.
To get this distribution you must go to
http://poseidon.furg.br/index.php?option=com_frontpage&Itemid=1

I used this distrubution to show in my institution that linux ang GRASS are an alternative to other Arc-nnn software.

Sincerely yours

Leonidas

This is an extraordinarily timely request. Linux is a great OS, and a live
CD can make it available to Windows users without installing it. However, if
people are not interested in committing to installing Linux on their own
machine, then training on software that runs only on this OS doesn't help
much. I've taught with GRASS under Cygwin. It was possible, but a real pain
in a lab setting. But now you have a very nice alternative.

I'm copying below a notice that went out to the GRASS developers list within
the past hour. If you want, you CAN get an easy to install Windows version
of GRASS without Cygwin. One of my grad students tried out a version of a
couple weeks ago and reported it to be very nice and fast...and easy to
install. It is simply a zip file. The only thing that you might need to
install extra is a program called Mysys. I think that this is covered in the
readme.

I'm copying the binary maintainer, Moritz Lennert, in case he has something
else to add.

Subject: [GRASS-user] native winGRASS pre-alpha testers needed

Hello,

I have updated the GRASS native win package at

http://moritz.homelinux.org/grass/wingrass/

(see instructions in the README file)

We definitely need testers if we want to speed up development on this. I
don't have much time to spend on testing at the moment. Even though you
can use a variety of modules in winGRASS, we are still far from a really
usable port. Only testing (and fixing :wink: ) will get us there.

Great to hear such positive feedback !

I do wish to warn you, however, that this windows version is still in an early phase and many things do not work as they do in the *nix version. Also note that there are no xmonitors in this version, so the only way to display things is via the tcltk gis manager.

The best thing would be for you to try and see if you can do everything you want to do for your workshop, and if it does, then hope that during the workshop noone wants to try anything else :wink:

In any case, if you try it, please give us a feedback.

You also have to install TclTk. We hope to include this in a future version, but currently this is a dependency.

Msys is necessary if you want to run some of the script modules which are full of *nix "shellisms".

Moritz

You can do *almost* anything from the GUI that you can do from the command
line. Apparently, nviz is the biggest problem--but I don't know why it
shouldn't run.

Maybe Cygwin is a bit improved now? Did you try 6.2.1? We have made
the install a bit easier now with good automatic dependency hinting.

It still takes a little time to install, but should be much smoother- it
might be worth the trouble of re-testing on 1 machine.

http://grass.ibiblio.org/grass62/binary/mswindows/

If all Cygwin, Linux LiveCD, experimental 6.3 Native versions don't
work, there is some access to the GRASS toolbox in QGIS 0.8 for Win?

Using PCLOS as your distro, it is easy to set up a custom install, then run mklivecd to turn your install into a LiveCD. So if your system does not enable network access (you'll still need your loopback device) nor enables HDD access, your LiveCD won't either.

This article describes how to do this with QGIS, but installing GRASS instead/as well will work just as well.

http://qgis.org/content/view/63/65/

PCLOS is focussed very much on ease of use, & I have found non-Linux users to be more comfortable with it than Knoppix LiveCD's. Very much a matter of opinion though :slight_smile:

HTH,
