| 09:42 | <alkisg> Check your ltsp.conf for errors
| |
| 09:49 | <tru_tru> alkisg: as expected, lts2004-desktop based ltsp server + "ltsp image /" works out of the box
| |
| 09:49 | <alkisg> 👍
| |
| 09:52 | <tru_tru> what is the usual procedure to add a package on a booted ltsp client? ie I want to add https://github.com/apptainer/apptainer/releases/download/v1.1.5/apptainer_1.1.5_amd64.deb, I assume wrongly that I just neede to apt install from the ltsp server and it would magically appear on the client. I also tried to apt instll from the client without success.
| |
| 09:53 | <alkisg> You apt install it to the server and then run ltsp image
| |
| 10:11 | <tru_tru> ok, I will boot my toy system and try :P

| 14:58 | <tru_tru> ltsp image: done, but the client is not seeing the newly installed package on the server, I assume that I also need to reboot the client
| |
| 16:14 | <alkisg> Yes

| 18:23 | sunweaver is now away: not here ... | |
| 18:34 | ricotz is now away: I'm busy | |
| 19:54 | <quinox> you can apt-install on a running client to get packages to show up, it all disappears on shutdown in that case
| |
| 19:55 | I give all my users the root password to apt-install, then they can test stuff and tell me what to install on the server later

| 21:12 | <tru_tru> quinox: that is what I was expecting (being able to install on some kind of tmpfs overlay) on the "live" desktop/ltsp client
| |
| 21:14 | that is exactly what I have been doing on compute/diskless warewulf nodes, I am trying to do the same kind of tricks on ltsp for a classroom
| |
| 21:14 | rebooting the client for installing a package is annoying, imho
| |
| 21:15 | it's fine if it is side installed on a NFS read-only mount point, but clumsy if I need something from the distrib.
| |
| 21:24 | <quinox> oh, 1 trick: you need to run `apt update` first
| |
| 21:24 | since LTSP deletes the apt cache inside the client image to save space
| |
| 21:25 | so to install new software to test: `sudo -i; apt update; apt install <my-package>; exit; my-package`
| |
| 21:29 | <alkisg> Is warewulf similar to LTSP? I haven't heard about it before...
| |
| 21:42 | <tru_tru> alkisg: it was design a long time ago for HPC purpose, head node diskfull, compute node pxe and diskless mostly with infiniband and ethernet
| |
| 21:44 | it is not geared for classroom at all, ie GUI, or fancy epoptes to broadcast screen, lock users ...
| |
| 21:45 | warewulf is the framework used on openhpc.org to deploy the cluster nodes
| |
| 21:47 | lstp is the only tool that I am aware of that is teacher friendly (and not only geek/IT tuned)
| |
| 21:48 | I am just reluctant on the ubuntu dependancy, that why I will try to learn to only use debian, once I am fluent enough!
| |
| 21:49 | next stage is having ldap/freeipa as authentification method and then nfsv4 for shared HOME
| |
| 21:51 | or having /home on the local storage and eveything else LTSP managed to avoid network overloaded (ie designated user <-> desktop for the class duration),
| |
| 21:53 | * tru_tru waves good night | |
