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	?

17:20	<alkisg> !paste
17:20	<ltspbot> paste: To avoid channel flooding, please upload text longer than 3 lines to http://paste.debian.net. Don't forget to paste the resulting URL here.
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
