| 07:14 | <bieb> Ollie hows it going??
| |
| 07:14 | shawnp0wers has joined #ltsp | |
| 07:22 | <bieb> I had some issues with my ltsp image, Gadi and I worked through a bunch of stuff Friday, the outcome was to move the i386.img and recreate one by running ltsp-build-client.. all seemed to work fine except for 1 issue.. I am using likewise for my students to authenticate against our current AD server. The previous setup had their home dirs mapped to /home/JOHNMARSHALL/%user% and they were locked so no one but the user could get into them. Aft
| |
| 07:22 | Or.. what is the easiest way around this issue?
| |
| 07:29 | <alkisg> ...so no one but the user could get into them. Aft ==> the message was truncated at that point because it was too long
| |
| 07:33 | <bieb> sorry
| |
| 07:33 | After the rebuild the new home location is /home/local/JOHNMARSHALL/%user% and these dirs are open. How can I change the home dir mapping?
| |
| 07:34 | <alkisg> I don't think the chroot has anything to do with the home dir location
| |
| 07:34 | So AFAIK your question is, "how can I move the home dir to a standard Ubuntu installation?", and has nothing to do with LTSP
| |
| 07:35 | So if I get it right, you can change that with `usermod` for existing users
| |
| 07:35 | For new users, it depends on how you create them
| |
| 07:36 | sathis has quit IRC | |
| 07:37 | <bieb> alkisg: what creates the /home/local/JOHNMARSHALL/%user% directory in the newest Ubuntu/Ltsp vs /home/JOHNMARSHALL/%user% from Ubuntu 9.04?
| |
| 07:38 | <alkisg> bieb: maybe likewise? The standard home for Ubuntu LTSP systems is always in /home
| |
| 07:38 | <bieb> hmmm..
| |
| 07:38 | <alkisg> So that /home/local/JOHNMARSHALL/%user% might be likewise-specific, so asking there would probably help you more than asking here in #ltsp
| |
| 07:39 | <bieb> ok.. will have to look into likewise info..
| |
| 07:39 | I updated likewise during the upgrade and rebuild of the client
| |
| 07:39 | <alkisg> The chroot doesn't matter
| |
| 07:39 | You don't have to even mention that you're using LTSP
| |
| 07:40 | If you just login on the server, you'll get the same home dir as if you login on the client
| |
| 07:40 | <bieb> gotcha

| |
| 10:18 | <bieb> alkisg: I looked through some stuff at likewise.. I am not finding the setting.. I am going to copy the user home dirs over.. is this the best way to copy??
| |
| 10:18 | yes | cp /home/JOHNMARSHALL/* /home/local/JOHNMARSHALL
| |
| 10:19 | obviously I would do this as sudo..
| |
| 10:19 | :)
| |
| 10:19 | <alkisg> bieb: sudo mv /home/local/* /home/
| |
| 10:19 | patrickmw has joined #ltsp | |
| 10:20 | <alkisg> Ah moment
| |
| 10:20 | I misread
| |
| 10:20 | <bieb> will a move "merge" directories
| |
| 10:20 | <mnemoc> hi, has anyone tried ltsp using efika mx clients? (cortex a8, good ubuntu support) they just dropped them to $129
| |
| 10:20 | <alkisg> bieb: JOHNMARSHALL is the domain? And you have homedirs under that?
| |
| 10:21 | jhutchins_lt has joined #ltsp | |
| 10:21 | <bieb> yeah.. the old setup had them in /home/JOHNMARSHALL now they go to /home/local/JOHNMARSHALL
| |
| 10:22 | shawnp0wers has quit IRC | |
| 10:22 | <vagrantc> mnemoc: yes, i've been working with the efikamx
| |
| 10:23 | <ogra> mnemoc, 129 is for the netbook, the nettop is a 95 afaik
| |
| 10:23 | <vagrantc> wow
| |
| 10:23 | <mnemoc> ogra: 95€ or USD$129
| |
| 10:23 | <ogra> oh, indeed
| |
| 10:24 | <mnemoc> vagrantc: worths the try? can one use adapter for vga or only digitial dvi?
| |
| 10:24 | <vagrantc> mnemoc: they don't support booting from the network, so you need to copy the kernel to SD or flash...
| |
| 10:24 | mnemoc: i think you can get DVI adapters for cheap, but VGA adapters are expensive
| |
| 10:24 | <ogra> you should be able to boot from network if you have a proper u-boot config
| |
| 10:24 | but u-boot still needs the SD
| |
| 10:25 | <mnemoc> their uboot code is available from gitorious
| |
| 10:25 | <vagrantc> ogra: i've been told by the efikamx devs that because the ethernet is implemented in usb it won't support network booting any time soon
| |
| 10:25 | <alkisg> bieb: one method: sudo rsync -av /home/JOHNMARSHALL /home/local/JOHNMARSHALL
| |
| 10:25 | <ogra> vagrantc, ah, yeah, that might be
| |
| 10:25 | <mnemoc> maybe tftp sopport faking pxeboot could be added...
| |
| 10:25 | <ogra> mnemoc, wont help
| |
| 10:25 | <vagrantc> which brings up another point, the ethernet on the efikamx is usb ... so it's not particularly fast
| |
| 10:25 | <mnemoc> vagrantc: ouch :(
| |
| 10:26 | <ogra> if you dont have the NIC available in the bootloader, tftp wont work
| |
| 10:26 | <bieb> alkisg: awesome.. thanks
| |
| 10:26 | <alkisg> maybe they could add a gpxe driver and put that to local storage
| |
| 10:26 | <vagrantc> mnemoc: i did work on some hacks to use KEXEC so that you could load a kernel from SD/flash, boot to the network, and load a kernel/initrd off the network
| |
| 10:26 | <mnemoc> vagrantc: worked?
| |
| 10:26 | <vagrantc> that way you can always run a current kernel without having to reflash all the time
| |
| 10:27 | mnemoc: i haven't had a kernel that supports the efikamx and kexec
| |
| 10:27 | worked on i386, though
| |
| 10:27 | ogra: any recommendations for an arm-based thin client?
| |
| 10:28 | <ogra> vagrantc, beagle XM ... cheap, available, many ports onboard, u-boot has support for the usb NIC builtin
| |
| 10:28 | <mnemoc> manufacturers abuse in the prices of x86 thin clients, they should all die
| |
| 10:28 | <ogra> 800MHz/512M
| |
| 10:28 | needs microSD for booting ...
| |
| 10:29 | <mnemoc> ogra: chassis is a problem with those TI boards.... cool for your own desk, but can't be deployed safely in the wild
| |
| 10:29 | <vagrantc> sounds like the efikasb is US$200, and the smarttop is US$130
| |
| 10:29 | <mnemoc> vagrantc: yes
| |
| 10:29 | smarttop has 8G of storage
| |
| 10:30 | <ogra> mnemoc, ??
| |
| 10:30 | they are sold with cases
| |
| 10:30 | if you order at the right place
| |
| 10:30 | <mnemoc> ogra: url?
| |
| 10:30 | <vagrantc> i was given an efikamx smarttop to test out Debian LTSP ... mixed results
| |
| 10:31 | <ogra> it should theoretically work
| |
| 10:31 | <vagrantc> ogra: what sort of video output does beagle XM have?
| |
| 10:31 | <bieb> alkisg: Do I need an asterisk after johnmarshall in the first part?? udo rsync -av /home/JOHNMARSHALL/* /home/local/JOHNMARSHALL
| |
| 10:31 | <ogra> i had LTSP booting in ubuntu with the imx51 babbage board
| |
| 10:31 | largely the same arch
| |
| 10:32 | <mnemoc> is the idea of running the client from the internal SSD (instead of network) too evil?
| |
| 10:32 | <vagrantc> not necessarily...
| |
| 10:32 | <mnemoc> client doesn't need to change that much...
| |
| 10:32 | <alkisg> bieb: no, but I missed a slash: sudo rsync -av /home/JOHNMARSHALL/ /home/local/JOHNMARSHALL
| |
| 10:32 | <mnemoc> i mean, updating once per semester should be enough.... :p
| |
| 10:32 | <ogra> just defeats the purpose of central maintenance
| |
| 10:33 | <vagrantc> i like to keep current on security updates
| |
| 10:33 | <bieb> alkisg: great!! thanks...
| |
| 10:33 | <vagrantc> but you could set them up to auto-update or something, probably
| |
| 10:33 | <ogra> especially in school environments you should care for security updates regulary :)
| |
| 10:33 | <mnemoc> good point :)
| |
| 10:34 | <alkisg> Some people here are using windows 98. They don't bother with security updates :D
| |
| 10:34 | <vagrantc> doesn't mean they can't start thinking about it :)
| |
| 10:34 | garymc has joined #ltsp | |
| 10:34 | <ogra> yeah, you should be able to have a script in initramthat checks /boot against the running kernel and updates the SD automaticallyfs
| |
| 10:34 | *initramfs
| |
| 10:35 | <alkisg> It'd be nice to have the ltsp initramfs scripts auto-detect if they're booting locally or from nbd/nfs etc
| |
| 10:35 | <garymc> Hi anyone know if WYSE thin clients work with LTSP?
| |
| 10:35 | I cant seem to get them to PXE boot
| |
| 10:35 | <alkisg> So that the user would only change the kernel param, not call update-initramfs and stuff
| |
| 10:36 | <ogra> alkisg, initramfs.conf has that ;)
| |
| 10:36 | <alkisg> ogra: we're messing it up though
| |
| 10:36 | Forcing BOOT=ltsp_nbd etc
| |
| 10:36 | <ogra> fix it :)
| |
| 10:36 | <alkisg> There are some parts to the ubuntu packaging tree, I don't have access to that
| |
| 10:36 | I filed bugs though
| |
| 10:37 | dobber has quit IRC | |
| 10:40 | <garymc> so anyone any idea?
| |
| 10:41 | <alkisg> Mentioning specific error messages might help
| |
| 10:41 | <vagrantc> garymc: some models are just regular computers, but if you can't get it to PXE boot, you won't likely get it to work with LTSP ... unless you can figure out a way to load gPXE/iPXE/etherboot
| |
| 10:47 | <garymc> there ar eno specific error message, they just boot up and its like a windows enviroment and looks for Citrix server.
| |
| 10:48 | I just thought they might have had boot options like my HP thin clients

| |

| 11:13 | <tyrion-mx> Hello I installed ltsp and configured dnsmasq to act as a proxy dhcp
| |
| 11:14 | I can login with a thin client, but I get an empty desktop
| |
| 11:14 | I can't even logout, is this normal?
| |
| 11:20 | <garymc> anyone used WYSE thin clients for LTSP?

| 11:53 | <bieb> alkisg: after the rsync of the directories, the students cant login, the error is "Could not chdir to hom directory /home/local/JOHNMARSHALL/%user%, permission is denied
| |
| 11:53 | <alkisg> bieb: did the old directories have the same UIDs/GIDs?
| |
| 11:53 | upload this to pastebin: ls -l /home/local/JOHNMARSHALL
| |
| 11:54 | <bieb> userIDs are the same.. how do I check GIDs?
| |
| 11:57 | shawnp0wers has joined #ltsp | |
| 12:08 | <bieb> alkisg: I figured it out.. when the rsync does it's initial touch of all the directories, it sets them to drwx------ and root:root, once it completes the sync of the students directory it changes back allowing them to login
