<garymc>
I would like to install LTSP ubuntu 64 bit on a server, where can I get a cd to download and install onto my new server?
13:48
<Hyperbyte>
garymc, from the Ubuntu website?
13:48
Or wait, you want an actual cd?
13:49
<garymc>
no i can make a cd from iso
13:49
I just found one
13:49
Alternate Ubuntu 64 bit thing
13:49
<Hyperbyte>
On ubuntu.com I hope?
13:49
Altenate Ubuntu?
13:49
<garymc>
at this link http://releases.ubuntu.com/releases/10.04/
13:49
is this right ^ ?
13:49
<Hyperbyte>
Stop for a second.
13:50
<garymc>
ok
13:50
<Hyperbyte>
You need to slow down, and investigate a little before you go and install something.
13:50
<garymc>
I done a 32 bit install last year, I used Alternate one
13:50
<Hyperbyte>
There are several different spins of Ubuntu... are you going to use Ubuntu in an educational environment?
13:50cyberorg has joined IRC (cyberorg!~cyberorg@opensuse/member/Cyberorg)
13:51
<Hyperbyte>
If so, you might be better off picking Edubuntu.
13:51
Then there's different versions to choose from.
13:52
There are releases every six months I believe, with every two years an LTS release.
13:52
LTS release are supported much longer than the other releases. If you don't plan on upgrading your server constantly, it might be better to use an LTS release.
13:52
11.04 is the current time based release, 10.04 is the newest LTS release.
13:53
Regular Ubuntu you should get from here:
13:53
http://www.ubuntu.com/download
13:54
<alkisg>
Hyperbyte: you might want to write a wiki page with all that info :P :D :D
13:55
<Hyperbyte>
alkisg, there are.
13:55
=)
13:55
<garymc>
so i want to use this software in my business, so my users can access the internet and stuff from their thin clients. Is edUbuntu gonna be my best soloution
13:56
<Hyperbyte>
https://help.ubuntu.com/community/Beginners/FAQ
13:56
:)
13:59
garymc: also useful for you: http://www.psychocats.net/ubuntu/whichbuntu
13:59
<alkisg>
Also, a x64 alternate cd will give you an amd64 chroot by default
13:59
If your clients are i386, you'll need to delete + recreate it with ltsp-build-client
14:03
<garymc>
sounds lik a nightmare

Two shell commands? Hmmm :)
14:05
<garymc>
ok so i need to find out what i need
14:08andygraybeal has joined IRC (andygraybeal!~andy.gray@obsidian.casanueva.com)
14:10
<Hyperbyte>
garymc, would you like to configure a whole system yourself?
14:10
<garymc>
i have before used Alternate disk
14:10
<Hyperbyte>
As in, do you prefer changing every little detail, customizing the configuration to suit your needs, experimenting with different ways of configuration?
14:10
<garymc>
and i currently have a working setup, but the system is slow now
14:11
so I bought more moreful server which is 64 bit
14:11
so I want to upgrade hardware
14:11
my employees only use the email , open office and internet on the system and we use thin clients

<Hyperbyte>
garymc, I get the feeling you have a lot of learning to do about Linux. Keep this in mind while you install LTSP, else you'll get frustrated really quickly.
14:12
Either way, you have the information you looked for, from the links I gave you earlier. I need to get some work done.
14:12
<garymc>
ok thanks

I am having a problem with local devices.
15:27
USB sticks seem to work OK.
15:27
The problem is with CD and DVDs.
15:28
They cannot be played.
15:28
Checked permissions on the folder and files and that seems to be the problem.
15:28
Nautilus says the user can not access the folder.
15:29
Checking on the command line give this:
15:29
:/media$ sudo ls -l ahenderson/
15:29
ls: cannot access ahenderson/cdrom: Permission denied
15:29
total 0
15:29
d????????? ? ? ? ? ? cdrom
15:29
Really weird.
15:30
Anyone got CD and DVD playing on local devices on the clients?
15:30
<Hyperbyte>
Of course "anyone" has. LTSP isn't a broken piece of software. :)
15:31
<frederickjh>
I meant any one on list. ;)
15:31
Any ideas what I should check?
15:31
Or is there a how to somewhere?
15:32
<Hyperbyte>
Well, I know there's a problem with UDF formatted disks in the LTSP included with Ubuntu.
15:32
<frederickjh>
The USB sticks seem to work out of the box on LTSP 5.2 but the CD and DVDs not.
15:32
UDF? What is that?
15:33
Interestingly the CD drive shows up on the server in Nautilus.
15:34
However I can not access in and if I go to the folder it should be in /media/username/ it is empty.

15:43
<frederickjh>
Hyperbyte, does this work on your LTSP setup?
15:44
Being able to access a CD or DVD in a drive on the client?
15:48
<Hyperbyte>
Yes, it works, even with a USB CD/DVD drive.
15:48
I'm sorry, I'm too busy to help you debug this at the moment.
15:48
Stick around.

frederickjh: put the cd in your server or in another ubuntu machine, and see if nautilus says "udf volume", or if `sudo fdisk -l` reports it as udf

<frederickjh>
alkisg, I did the `sudo fdisk -l` command and the CD does not even show up. My harddrive and the partion and also the USB stick but the CD does not show up.
21:24
<alkisg>
frederickjh: does sudo blkid show it?
21:25
Or, cat /proc/mounts
21:26
<frederickjh>
sudo blkid does not show it but the command mount does.
21:26
<alkisg>
Is it udf?
21:26
<frederickjh>
/dev/sr0 /media/VOYAGE_OF_THE_DAWN_TREADER_DVD udf ro,nosuid,nodev,relatime,uid=1000,gid=1000,umask=77,iocharset=utf8 0 0
21:26
<alkisg>
Yup, udf
21:26
Known problem, it was fixed in later ltsp versions
21:26
<frederickjh>
Do you meant utf?
21:26
Ah
21:27
now I see it.
21:27
<alkisg>
There are 2 main filesystems for CDs
21:27
<frederickjh>
udf
21:27
<alkisg>
iso, and udf
21:27
Which distro/version are you using?
21:27
<frederickjh>
Lucid Ubuntu 10.04
21:27
LTS
21:27
<alkisg>
The fix came after lucid
21:27
So you need a backport to see it
21:27
<frederickjh>
And has not been backported.
21:28
<alkisg>
Not officially, I guess you can find it in ppas
21:28
<frederickjh>
Let me check if I have backports enabled.
21:28
<alkisg>
No need
21:28
There are no official backports for lucid
21:28
<frederickjh>
Oh, ok
21:28
Ah, OK
21:28
<alkisg>
Only in PPAs, or if you backport it manually
21:28
Search the irclogs, you can find many people having the same problem + links to the solution
21:29
<frederickjh>
What would I be looking for in the PPAs?
21:29
ok
21:29
<Hyperbyte>
alkisg, I think the UDF fix isn't in any Ubuntu distribution. I had the same problem on Natty.
21:29
<alkisg>
http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltspfs-trunk/revision/148
21:30
There's the fix
21:30
So ltspfs 0.8 is needed
21:30
<Hyperbyte>
You gave me a cdpinger binary which fixed it for me.
21:30
<alkisg>
http://packages.ubuntu.com/search?keywords=ltspfs
21:30
Natty has 0.7-2, so it's not there
21:30
Oneiric has 0.9
21:30
So it's fixed there
21:31
There's an ltsp daily builds ppa, it's surely there too
21:31
https://launchpad.net/~ltsp-upstream/+archive/daily/+packages
21:32
And specifically, frederickjh you can manually install one of the debs there: https://launchpad.net/~ltsp-upstream/+archive/daily/+sourcepub/1856303/+listing-archive-extra
21:32
(in the chroot)
21:32
This one, probably: https://launchpad.net/~ltsp-upstream/+archive/daily/+files/ltspfsd-core_0.9%2Bbzr152%2B201108121617-0ubuntu1%2B3%7Elucid1_i386.deb
21:33
(or you can extract it and get the cdpinger executable)
21:33
<frederickjh>
ok, thanks alkisg and Hyperbyte for the help and info.
21:36
Do I just need to install this on he server?
21:36
Or the client too?
21:38
So, with the cdpinger is that fix basically replace the binary after extracting it from the deb?
21:39
<alkisg>
Yes
21:39
On the server chroot, and run ltsp-update-image
21:39
<frederickjh>
So actually it need to go on the client image.
21:39
Not on the server.
21:39
<alkisg>
Yes
21:40
<frederickjh>
Thanks again. I am going to call it a night. Bye for now.
