| 09:01 | <eirikb> Hi. I'm trying to run ltsp locally in Debian on VBox. For now I'm just trying to make it work. Are there any scripts online I can follow to make this work? My current solution doesn't work, looks like this: https://gist.github.com/eirikb/5a363214b9e2db29365ce2920771c7ab
| |
| 09:05 | <quinox> TFTP timeout means the client can't connect to the TFTP; is the IP correct? Is TFTP running on it?
| |
| 09:07 | <eirikb> I haven't installed anything beside what is in the gist, so no, nothing like atftpd
| |
| 09:08 | Should I replace isc-dhcp-server with dnsmasq which should also support tftp?
| |
| 10:06 | I was able to make it boot using dnsmasq, will create a gist soon. Must go out for a bit
| |
| 10:15 | <alkisg> !ltsp-pnp
| |
| 10:15 | <ltsp> ltsp-pnp: ltsp-pnp is the recommented method to install and maintain LTSP for "usual" setups. Since it doesn't involve chroots, it requires little to no command line to maintain it. It automatically supports both thin and fat ltsp clients. https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
| |
| 10:15 | <alkisg> This is the recommended method; try as close as this as you can with debian
| |
| 10:15 | Most commands except for the ppa should work
| |
| 10:26 | <eirikb> I need a ppa to install it?
| |
| 10:31 | I have been looking at https://wiki.debian.org/LTSP/Howto and there ltsp-pnp is mentioned under "Installing LTSP with older versions"
| |
| 10:34 | This is my current script: https://gist.github.com/eirikb/5584a378ec76a7a58d2cc4e4a9fcfcce I think that is the minimum to make it work. Script is executed on a plain Debian
| |
| 11:04 | <alkisg> Your script is using isc-dhcp and nfs, while the recommended one nowadays is dnsmasq and nbd
| |
| 11:05 | <eirikb> Not my last gist
| |
| 11:05 | <alkisg> No, you don't need a ppa to make ltsp-pnp work in debian
| |
| 11:05 | The last one says nfs-kernel-server
| |
| 11:06 | <eirikb> Yes, not sure if that is actually in use, it's only in the install. no idea how data is sent to the client. I'm doing a clean install now to see if I need it or not, but it takes a while to install ltsp
| |
| 11:06 | <alkisg> Also ltsp-pnp doesn't use ltsp-build-client at all
| |
| 11:06 | Installing ltsp over an existing installation takes 1 minute + 9 waiting

| 19:24 | <eirikb> I was able to make my previous gist work fine, but not with fat clients, the --fat-client flag wanted an option, but I'm not sure what. Only --fat-client-desktop was mentioned in man, and without any options. This is my current gist using the ltsp-update-image command, but it won't boot on pxe client as /var/lib/tftpboot/ltsp/mnt/pxelinux.0 can't b

| 19:38 | <alkisg> eirikb: you're trying a weird ltsp setup; if it's your first time better stick with the normal setup
| |
| 19:40 | <eirikb> Where can I find a guide for a normal setup?
| |
| 19:40 | <alkisg> !ltsp-pnp
| |
| 19:40 | <ltsp> ltsp-pnp: ltsp-pnp is the recommented method to install and maintain LTSP for "usual" setups. Since it doesn't involve chroots, it requires little to no command line to maintain it. It automatically supports both thin and fat ltsp clients. https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
| |
| 19:40 | <alkisg> I told you before :)
| |
| 19:41 | Just don't add the ppa, since you're using debian
| |
| 19:41 | Reformat and follow that
| |
| 19:41 | <eirikb> Yes, I tried to base my setup on that. I don't actually know what ltsp-pnp is, it's not an executable, not a package
| |
| 20:15 | <alkisg> it's the new recommended way to setup ltsp
| |
| 20:16 | instead of running ltsp-build-client
| |
| 20:16 | it's using dnsmasq instead of isc-dhcp/tftpd-hpa, and the server / as a template instead of a chroot
| |
| 20:17 | <eirikb> I am using dnsmasq. I replaced ltsp-build-client with ltsp-update-image now as in your link
| |
| 20:19 | <alkisg> Did you remove your chroot?
| |
| 20:19 | <eirikb> Where is my chroot?
| |
| 20:19 | <alkisg> ltsp-pnp doesn't use a chroot
| |
| 20:19 | In /opt/ltsp/amd64
| |
| 20:19 | (or i386)
| |
| 20:19 | <eirikb> I haven't run ltsp-build-client
| |
| 20:20 | <alkisg> What's the output of sudo ltsp-info? pastebin it
| |
| 20:20 | !pastebin
| |
| 20:20 | <ltsp> pastebin: try !paste
| |
| 20:20 | <alkisg> !paste

| |
| 20:20 | <eirikb> Before or after my install script has run?
| |
| 20:20 | <alkisg> Whatever; to see what you have now
| |
| 20:20 | (before, if possible)
| |
| 20:21 | <eirikb> Here is before: https://gist.github.com/eirikb/0c09e34b2952a43c0d0c3f34a8d24582
| |
| 20:22 | I can give you after in a while, but the script takes several minutes to run (ltsp-update-image is the slow part). Here is the latest version of my install script: https://gist.github.com/eirikb/3656cda39c00c997933c01b6d9dddf76
| |
| 20:26 | <alkisg> It's -c /
| |
| 20:27 | <eirikb> -c throws the same error
| |
| 20:27 | <alkisg> sudo ltsp-update-image -c /
| |
| 20:27 | Run that command and paste the output
| |
| 20:28 | Also, please read the ltsp-pnp page
| |
| 20:28 | You didn't install the necessary packages
| |
| 20:28 | <eirikb> Script //usr/share/ltsp/ltsp-cleanup does not exist, cannot cleanup the chroot.
| |
| 20:28 | <alkisg> Yes, you didn't read the page yet
| |
| 20:28 | !ltsp-pnp

| |
| 20:28 | <alkisg> 3rd time now :)
| |
| 20:28 | There's an apt-get install line there. Please read it.
| |
| 20:29 | <eirikb> You mean ltsp-client? dnsmasq is already installed, the ubuntu-stuff shouldn't be related, and ltsp-config is also installed
| |
| 20:30 | <alkisg> yes
| |
| 20:30 | <eirikb> Very well, trying that now
| |
| 20:34 | Now the error is gone, thanks
| |
| 20:43 | It works. And from a quick test it seems this time the client is fat (trying to grep in ps if apps on the PXE client are visible on server, and they're not)
| |
| 20:44 | Now I need to see if I can make it run from my /mnt location (mounted vdi image), and if I can prevent ltsp-update-image from installing anything extra
| |
| 20:48 | Hmm, ltsp-client must be installed on the client?
| |
| 20:56 | I could never have guessed that booting an OS from a hdd located on a network could be this difficult
| |

| 21:10 | <alkisg> eirikb: yes, ltsp-client needs to be installed in the vdi file
| |
| 21:12 | <eirikb> What if it's a distro where it might not be easily available? Or perhaps then diskless boot would be difficult anyway? I imagined I somehow could just point to a vdi and let the clients boot from it directly
| |
| 21:16 | I hoped I could simply get the clients to boot from the vdi as if it were a live-cd image, without change to the vdi
| |
| 21:22 | I guess this will suffice for now. I can probably pre-package the client with lstp-client even when it's run locally. Thanks for all the help alkisg
