| 05:04 | <alkaff> Hello
| |
| 05:04 | I'm new to LTSP and would like to set up a test cluster
| |
| 05:05 | I plan to have 2 diskless fat clients and 1 LTSP server as a start
| |
| 05:06 | So far I've followed the tutorial (https://ltsp.org/docs/installation/) using the chrootless method for the image and it seems to work
| |
| 05:07 | Now I would like to enable SSH on start on the diskless clients so that I can remote access to the clients from the LTSP server after netbooting
| |
| 05:08 | I've found that by manually entering "ssh-keygen -A" and "service start ssh" on the clients works but is there a way to do it automatically?
| |
| 05:10 | I've also tried including RCFILE_01="ssh-keygen -A" and RCFILE_02="service ssh start" in the /etc/ltsp/ltsp.conf file but it doesn't seem to work
| |
| 05:10 | Currently I'm running Debian Buster x64 as the OS
| |
| 05:11 | Could anyone help me please?
| |
| 05:52 | <quinox> SSH daemon gets disabled by default
| |
| 05:52 | there is some setting you can use to not disable it
| |
| 05:53 | https://ltsp.org/man/ltsp.conf/ search for ssh
| |
| 05:53 | it describes KEEP_SYSTEM_SERVICES and MASK_SYSTEM_SERVICES
| |
| 06:10 | <alkisg> alkaff: ssh in the chroot is unsafe, as the private keys as exposed to the public
| |
| 06:11 | That's why epoptes is recommended instead
| |
| 06:11 | Nevertheless, if you do want ssh, yeah, just put it in KEEP_SYSTEM_SERVICES
| |
| 06:11 | And also omit the ssh keys from ltsp-image.excludes
| |
| 06:12 | See OMIT_IMAGE_EXCLUDES ltsp.conf parameter

| 15:23 | <markit> hi, how can I disable ubuntu from checking for updates? I've (I think) 2 problems, the automatic "OS based" check and the KDE "discovery" check. I've not been able to disable Discovery and probably I will have to purge it (sigh!)
| |
| 15:24 | don't want 30 clients to fetch sources at every boot... not notify the users about possible updates they, in any case, can't install
| |
| 15:34 | <||cw> for the package lists, /etc/apt/apt.conf.d/10periodic
| |
| 15:35 | seem like it would be a good idea for ltsp to disable this by default when building clients
| |
| 15:35 | <alkisg> LTSP automatically disables updates for clients, but I think NOT for snap
| |
| 15:35 | * alkisg isn't using snap | |
| 15:35 | * ||cw didn't check | |
| 15:36 | <||cw> I purge snap first thing on my sytems :)
| |
| 15:36 | early versions had some real resource hogging issues. maybe that's been fix?
| |
| 15:40 | <alkisg> No idea, I purge it too. I do not like it, I think it solves the wrong problem in the wrong way..
| |
| 15:43 | <markit> alkisg: magic! how do you disable updates for clients?
| |
| 15:44 | <alkisg> markit: you mean ltsp? Check /usr/share/ltsp/client/init
| |
| 15:45 | <markit> ||cw: in kubuntu 20.04 I've no /etc/apt/apt.conf.d/10periodic

| 15:49 | <markit> alkisg: maybe in addition to gnome-software-service you should disable also /etc/xdg/autostart/org.kde.discover.notifier.desktop :)
| |
| 15:50 | <alkisg> Put it to MASK_SESSION_SERVICES
| |
| 15:50 | !ltsp.conf
| |
| 15:50 | <ltspbot`> ltsp.conf: Configuration file for LTSP: https://ltsp.org/man/ltsp.conf/
| |
| 15:50 | <markit> great, I'll have a look thanks

| 15:52 | <markit> "See /usr/share/ltsp/client/init/56-rm-services.sh for the default" but I've not that file, I've /usr/share/ltsp/client/init/56-mask-services.sh if you want to fix the man page
| |
| 15:53 | <alkisg> Sure, let me fix that... (it's been renamed in the mean time)
| |
| 15:53 | <markit> the advantage of having a dumb "sysadmin" like me is that I can find every mistype of wrong file name in the doc ;P
| |
| 15:55 | btw, /etc/xdg/autostart/org.kde.discover.notifier.desktop is not a service, is just an "autostart", so I think I just have to empty it at POST_INIT_XX right?
| |
| 15:56 | <alkisg> Those are called services too, but session services instead of system services
| |
| 15:57 | <markit> so in MASK_SESSION_SERVICES I can just write MASK_SESSION_SERVICES=org.kde.discover.notifier.desktop ?
| |
| 15:57 | <alkisg> MASK_SESSION_SERVICES=org.kde.discover.notifier

| 16:16 | <markit> mmm doesn't work
| |
| 16:16 | I've the try icon with the notification of updates available
| |
| 16:16 | <alkisg> Was the file deleted?
| |
| 16:16 | Did you run ltsp initrd?
| |
| 16:16 | <markit> I did run ltsp initrd, what file deleted?
| |
| 16:17 | oh, in the client, let me check
| |
| 16:17 | <alkisg> Open a root shell from epoptes and see: ls /etc/xdg/autostart/org.kde.discover.notifier.desktop
| |
| 16:18 | <markit> the file has been deleted, so maybe there is something more
| |
| 16:18 | so frustrating.... would love "discover" program had some related setup
| |
| 16:20 | <alkisg> Doesn't KDE have user support? Can't you just ask them (or google) how to disable discover?
| |
| 16:20 | GodFather has joined IRC (GodFather!~rcc@wsip-66-210-242-210.ph.ph.cox.net) | |
| 16:20 | <alkisg> Why do you need to discover how to disable discover? :P
| |
| 16:20 | <markit> I've googled a lot, a lot of frustrated users, or old and not applicable (old "muon") solutions
| |
| 16:21 | <alkisg> Hrm, it's silly then if they don't allow users to easily blacklist some services
| |
| 16:21 | <markit> I'll try in the -dev channel, but I've had not that happy experiences in the past
| |
| 16:21 | <alkisg> No activity in askubuntu or stackexchange?
| |
| 16:21 | Usually there's good quality of answers there...
| |
| 16:22 | <markit> I've no more the notification in the "can'tsayhowcallit" part of the panel, but the "updates available" icon appears in any caseo
| |
| 16:22 | well, "who is so mad that does not want to have notification about updates?" whas the last answer I saw... I'll dig again tomorrow :)
| |
| 16:23 | <alkisg> True, notification about updates shouldn't hurt
| |
| 16:23 | Did you update before ltsp image?
| |
| 16:23 | <markit> I've also compared 14.04 to 20.04 performance (also real hw vs VMs), and 20.04 with new kde is 2x SLOWER
| |
| 16:23 | alkisg: ehm, no, I did not
| |
| 16:23 | I don't update because I'm trying to hide the notification...
| |
| 16:24 | so I need an "updatable system" that I don't update and I don't want to know about ;P
| |
| 16:25 | <alkisg> The updates in the clients aren't updated nor changed
| |
| 16:25 | They reflect the state when you run ltsp image
| |
| 16:25 | If you had updated then, the clients will never see an update message
| |
| 16:25 | If you haven't, they'll always see it
| |
| 16:25 | <markit> I see
| |
| 16:25 | <alkisg> It's not related to what you have on the server now. It's only what you had right before ltsp image
| |
| 16:26 | Frozen at that point; it doesn't check for even newer updates etc

| 17:27 | <douglas_br> Hello all
| |
| 17:29 | I did install windows in VM at LTSP. How does client run windows in client side? from Remina, maybe?
| |
| 17:39 | markit has left IRC (markit!~marco@mail.ammdomus.it, ) | |
| 17:39 | <alkisg> If you have good clients, they can run VMs too
| |
| 17:39 | Otherwise you need xfreerdp or remmina
| |
| 17:49 | <douglas_br> @alkis ahh yeah, sorry my stupid brain
