| 13:47 | <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?
| |
| 13:50 | cyberorg 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
| |
| 14:04 | andygraybeal has left IRC (andygraybeal!~andy.gray@obsidian.casanueva.com, Read error: Connection reset by peer) | |
| 14:04 | <alkisg> Two shell commands? Hmmm :)
| |
| 14:05 | <garymc> ok so i need to find out what i need
| |
| 14:08 | andygraybeal 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

| 14:12 | alkisg has left IRC (alkisg!~alkisg@ubuntu/member/alkisg, Ping timeout: 252 seconds) | |
| 14:12 | <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

| 15:27 | <frederickjh> 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.

| 21:24 | <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.
