| 02:18 | <iqpjgfj> Hi, after creating ltsp.conf (only for IMAGE_TO_RAM=1) I can't login on my client anymore. Fixed clients with MAC addresses arent an option since I want to use the image for diagnosing old laptops which come and go. How do I enable just using my host OS's login credentials? It works fine without ltsp.conf
| |
| 02:25 | <alkisg> Unfortunately the developer that contributed the IMAGE_TO_RAM code isn't very active in user support. Why do you need it for old laptops though? It just wastes RAM...
| |
| 02:35 | <iqpjgfj> It's just a measure of comfort, and 99% of the time the models I work with require a separate proprietary LAN adapter - which bottlenecks the amount of systems that can be tested at the same time. With ramboot I can just swap the cable to the next system.
| |
| 02:36 | Just tested it and its indeed the IMAGE_TO_RAM option that prevents me from logging in, and not the .conf file itself
| |
| 02:38 | <alkisg> Patches welcome, but personally I don't want to maintain code that I'm not using ..

| 14:54 | <RodrigoAlves[m]> Hello, can anyone help me?
| |
| 14:55 | I'm trying to configure a startup script in crontab ltsp, via /etc/ltsp/ltsp.conf, but the crontab configuration doesn't work
| |
| 14:55 | <alkisg> What's the ltsp.conf line for that?
| |
| 14:56 | <RodrigoAlves[m]> first I try to do it the way it is in the example in the documentation, but it still won't, and I also tried following the following plan:
| |
| 14:56 | https://github.com/ltsp/ltsp/discussions/454
| |
| 14:56 | woernie has left IRC (woernie!~werner@p5b296168.dip0.t-ipconnect.de, Remote host closed the connection) | |
| 14:57 | <RodrigoAlves[m]> alkisg: CRONTAB_x="50 11 * * * root /usr/sbin/poweroff"
| |
| 14:58 | it's in the customers section
| |
| 14:58 | <alkisg> So the startup script you're running is to poweroff at some specific time?
| |
| 15:01 | <RodrigoAlves[m]> no, no. I haven't put the script yet. first I'm testing the way it is in the documentation, but it doesn't work
| |
| 15:02 | <alkisg> So you put that exact line, and you run `ltsp initrd`, and you waited until 11:50, and the client didn't poweroff?
| |
| 15:03 | Are you sure you want a system script and not a user script, that runs inside the user session?
| |
| 15:03 | Because user session scripts are NOT the same as cron scripts
| |
| 15:05 | <RodrigoAlves[m]> alkisg: exactly
| |
| 15:05 | <alkisg> OK, run `sudo crontab -e` in the client and see if the line is there or not
| |
| 15:06 | <RodrigoAlves[m]> alkisg: are you saying this because of the "root" column?
| |
| 15:06 | <alkisg> No, because cron scripts do not have access to xorg (graphics)
| |
| 15:06 | <RodrigoAlves[m]> alkisg: Ok
| |
| 15:06 | <alkisg> They are background scripts, not session scripts
| |
| 15:07 | Also run this on the ltsp client: cat /etc/cron.d/ltsp
| |
| 15:08 | <RodrigoAlves[m]> alkisg: this path does not exist on the server...
| |
| 15:08 | <alkisg> Yes, try on the client, not on the server
| |
| 15:09 | <RodrigoAlves[m]> Ooww ok
| |
| 15:11 | <alkisg> "Are you sure you want a system..." <- I didn't understand here. Why would it be a system script? I have the CRONTAB option inside ltsp.conf
| |
| 15:11 | <alkisg> Cron is for running services in the background. /etc/xdg/autostart is for running scripts inside the user sessions
| |
| 15:14 | <RodrigoAlves[m]> only a moment
| |
| 15:34 | <alkisg> "OK, run `sudo crontab -e` in the..." <- there is nothing there, he opened the File "/tmp/crontab.qbiaE4/crontab" by nano, but my command is not there, and all lines are commented out
| |
| 15:34 | <alkisg> What about cat /etc/cron.d/ltsp ?
| |
| 15:45 | <RodrigoAlves[m]> sorry for the delay...
| |
| 15:46 | it displays my command, "50 11 * * * root command"
| |
| 15:46 | and says that it was generated by ltsp init
| |
| 15:56 | vagrantc has joined IRC (vagrantc!~vagrant@2600:3c01:e000:21:7:77:0:20) | |
| 16:03 | <alkisg> Ltsp does it's work then just fine
| |
| 16:04 | Was the command actually /usr/sbin/poweroff or something else?
| |
| 16:06 | <RodrigoAlves[m]> that was exactly
| |
| 16:06 | I will test with my script to see if it works
| |
| 16:07 | in that case should I allow the execution of the script right?
| |
| 16:09 | I put it like this: * * * * * root bash /iniciliazacao.sh
| |
| 16:22 | the script did not run... in "crontab -e" there is nothing. In "cat /etc/cron.d/ltsp" it shows my command, but even so it doesn't execute "* * * * * root bash /inicializacao.sh" ;(
| |
| 16:32 | <alkisg> Can you put your script to pastebin so that we can see why it doesn't run properly via cron?
| |
| 16:33 | For example it might be trying to access xorg
| |
| 16:55 | <RodrigoAlves[m]> <alkisg> "Can you put your script to..." <- you are saying no to put no /bin
| |
| 16:55 | ?

| |
| 17:28 | <alkisg> Rodrigo Alves: put inicializacao.sh there in paste.debian.net
| |
| 17:29 | Or test with a simple script, for example: CRONTAB_X="* * * * * root date >>/tmp/cron-test"
| |
| 17:33 | <RodrigoAlves[m]> <alkisg> "Rodrigo Alves: put inicializacao..." <- what is this channel about?
| |
| 17:34 | <alkisg> "Or test with a simple script..." <- Do I put it exactly like this?
| |
| 17:44 | <alkisg> "Rodrigo Alves: put inicializacao..." <- paste.debian.net/hidden/62e480e6
| |
| 17:45 | thus?

| 17:55 | <alkisg> Rodrigo Alves: yes, thus. Yes, the problem is that you can't run rdp from cron
| |
| 17:56 | Cron is about NOT GRAPHICS tasks, that do not show anything on the screen
| |
| 17:59 | <RodrigoAlves[m]> sorry, this is still getting on my mind ;(
| |
| 17:59 | do you know how i could do the specified task?
| |
| 18:01 | <alkisg> It's been discussed many times: https://github.com/ltsp/ltsp/discussions?discussions_q=xfreerdp
| |
| 18:01 | You just need a custom /usr/share/xsessions/your-session.desktop script
| |
| 18:01 | It's not related to cron at all
| |
| 18:06 | <RodrigoAlves[m]> Got it, I'll take a look. sorry for the mess
