Hey buddy,
Instead of using gradebook, use moodle instead.
it support in Ubuntu.
thanks

Hello Tim,
I am also an one man IT shop for a school.

Hello Folks:
I am the One Man IT shop for Medina Christian Academy, and am facing a
potential situation that i am trying to avert in the future. I am currently
a largely Windows XP (fully patched and updated) network built on a Windows
Server 2003 Active Directory domain. I have some samba servers for file
servers and an APACHE web development server. We have ~150 desktops spread
between the classrooms, offices and computer lab. The computers are mostly
roughly 5 year old Pentium 4 gateways mostly have 40 gb hdd, onboard sound
and video cards and between 512 and 1024 mb memory
I take it that the samba servers share the same RID database?
If you switch to Linux, you drop samba for all but remaining Windows hosts.
-- Printing -- we have a number of printers across the network -- couple
of which are all in one type units by keyocera - and all stations/users need
to be able to print -- so that means samba print server -- again -- probably
take some development work but i am pretty sure it can be done.
Been there, done that. You need to configure kerberos and in my case,
-- domain (or whatever its called in linux) -- users need to be able to
sign in on any computer, and have their files accessable similar to what
happens when a user logs into a windows domain.
winbind and add pam authentication via winbind and user info lookup via
winbind. Then you can keep the AD if that makes user management easier for
you or you do not wish to migrate user accounts or you will still have some
Windows clients left.
Best if it works with wine...otherwise, you will still need them XP
-- Our School management software / gradebook -- not available in linux,
but im wondering about using crossover office / wine or possibly VMWARE --
i'll need input on that -- its a client server app sort of the gradebook
writes out text files that are imported into the main application which is
based on microsoft access databases with a custom written interface -- might
have to run a Virtual windows 2003 server to run the server portion of it --
and like wine or something for the users to access it -- i dont know
licenses to run in a kvm guest or something.
You can choose to have one or more online (and maybe offsite) backup server
-- backup -- we have a quantum loader, so one way or another we'll need to
be able to back stuff up
loaded with big fat disks. I do not have tape backup anymore. With 500GB of
data and growing, the tape backup system is no joke. Might as well just do
HA and have multiple backup servers.
NFS, Gluster, lots of choices...all depend on how you want to manage your
-- file servers -- ive got a couple linux file servers now -- but they are
running samba i dont know how to share stuff via linux
data. But first, you first need to make sure that uids/gids are identical
across all Linux boxes...whether servers or desktops. If you will still have
a few Windows desktops for office staff, then it is best you keep the AD if
you need group policies on the remaining desktops or you could consider
converting over to NT style domains instead of AD.
Do you use group policies to limit what the kids can see? If so, the only
im sure there are things that i have forgotten so if anyone has ideas /
suggestions please chime in.
I am tentatively planning to use kubuntu, for the desktop environmen, and
this project (if it goes) at least for now would be deployed summer of 2010
for use beginning in the fall of 2010
easy to use equivalent on desktop environments available in Linux is KDE 3.x
using the kiosktool. With that, you can assign desktop profiles to groups
and control what the different users can see or use on their box.

Date: Sunday, April 5, 2009, 9:06 PMThis may help:
I'm back to using the open drivers right now because the
latest update
crashed the nvidia video on reboot. Downgrading the
proprietary
drivers from 180 to 173 doesn't help. I see that this
xorg issue has
been reported with ATI. Has anyone else experienced this
vith nvidia?
http://www.google.com/search?q=jaunty+nvidia+drivers&ie=utf-8&oe=utf-8&aq=t&rls=com.ubuntu:en-US:unofficial&client=firefox-a
The first hit said the 108.11 driver was the latest recommended driver.
Sorry, haven't installed jaunty yet so can't comment on it. However, it's
not too uncommen having to install a newer driver
especially after a new kernel is installed or perhaps it's a bug. If it
were me I'd do an 'aptitude search nvidia' to see what is availabe in the
proprietary drivers that might suit you needs. Also, reboot in recovery
mode and select xfix, let it run to completion, then continue the boot and
it might fix X. I assume that xfix is still there in Jaunty beta. You might
also google for your video chip+jaunty and perhaps locate the specific
nvidia module recommended for our card/chip. there are lots of googling
possibilities that may help solve your problem. HTH,

I haven't heard of xfix before, and there isn't a man page for it on my
system, nor a binary of that name in my path, and when I searched for it in
Synaptic, I only came up with libxfixes3, and it's companion packages of
libfixes-dbg, and libfixes-dev, no binary named xfix.
You say that it is accessible from within recovery console, where I've
never been before, so I'm assuming it is a menu entry within recovery
console somewhere. Is this right? I guess I really should boot into the
recovery console at least once, just to see what's there, can't learn
anything if I don't explore. 8-)

Greetings,
Previous to using the Jaunty beta, I had been using whatever the latest
version of Linux Mint is (6.x I think?) and their version of
gnome-system-monitor had always correctly displayed my RAM as being
3.0GiB but ever since switching to Ubuntu, it is now 2.9GiB.
While I fully acknowledge that this is superficial and absolutely
frivolous - I'm just curious as to why this could be, maybe a new patch
to gnome-system-monitor which handles the rounding up and down of these
numbers?
I doubt it's a rounding issue. One possibility is you have different
drivers, and an Ubuntu one is reserving some memory.

I do highly recommend a home partition.
Please advise and if it a re-install and accept from live CD welladvise as well, but I do want
a functioning home partition and do what I must do to maintain it's

Backing up and reinstalling would certainly be easiest for a new user.
My theory on repartitioning is that lossless repartitioning is possible
(http://blogcritics.org/archives/2007/04/01/095755.php) but it's never
guaranteed. So, you have to backup first, and if you're going to backup
first...you might as well blow everything away.
As far as advice, not sure exactly what you're asking. It always helps
to paste in your current partition layout when asking such questions. Run:
sudo parted /dev/sda print
That will print your partition table. Then, we can give more informed
advice.

From what I understand, it is dangerous to share /home directories or

other things, incompatibilities can occur.
I want to b able to access with read/write permissions, what is in the

sda8 is to be mounted at /data in your filesystem, nothing wrong with

read/write access, and so I assumed that I would be able to similarly access
these partitions from Ubuntu.

I just thought of something I haven't yet asked you. You did create the
mount points in your filesystem before trying to mount them, didn't you,
or are you expecting them to be created from the info in fstab?
I figured that that would be done on rebooting, after putting the new
entries in the fstab file.

I checked out your town on it's web site. I was pretty much raised in small
towns like that. [32 different ones by the time I was a sophomore in High
School, as my Dad followed heavy construction jobs, wherever they popped up,
for a living.]
I like your door icons for your links. 8-) That's a pretty intuitive
navigation artifice. My last two years of high school I finally got to spend
the rest of, in one school in a very small Indian reservation town, and my
graduating class consisted of 32 graduates, so I'm no stranger to your sort
of town.
I did notice that on your front page, the description text lines with the
black backgrounds beneath the picture of the town, are arranged in four
overlapping rows, with each lower row partially obscuring the text in the
line above it.
Oh yeah, I just remembered that that is probably my fault, as I have the
font sizes in my browser set larger than the defaults, to make it easier to
read web pages, as so many web masters these days seem to be using tiny
difficult to read text for some reason. Old eyes need big text! 8-)
