<Guest89884>
hallo! Is this chat supposed to post a question for ltsp or should I better user a forum?
12:03
<kione>
You are in good hands, here

<Guest89884>
Thanks! Unfortunately right now, I am the only one to administer our ltsp-server, and didn't set it up so I just have an idea of how it works and some basic knowledge.
12:09
All I want for now, is to install an application for every user. It's an java app, so all I have to do is to put the folder to a place where everybody can start the script-file. Afterwards I would like to put a .desktop entry and add it to the auto start programs. Everything I tried didn't work, because the files disappeard afterwards.
12:09
Where should I put ot or, how can I found out where to put it? In the ltsp-server or the chroot image? There is a "rofs"-folder, could this be the place?
12:10
I know that some folders are handed through from ltsp to chroot
12:11
we are running ubuntu 12.04 with cinnamon desktop
12:12
I am grateful for any hint
12:15
I put it to /usr/local/bin/ in the ltsp-server, and can reach it from client, but it won't start
12:22
and any tips about the .desktop files and autostart thing? I read through a lot of documentation, but our implementation seems to be different

<kione>
ltsp-pnp? according to the wiki https://wiki.debian.org/LTSP/Howto you should re-create the squashfs-image after adding software to the server

Guest89884: if you have an /opt/ltsp/i386 folder, then you're using a chroot. Are you using a chroot?
16:51
Also, if you have the /opt/ltsp/i386/usr/share/xsessions folder, it means you're using fat clients.
16:51
So in order for us to tell you where to put the .desktop file etc, we need to know if you're using a chroot (or ltsp-pnp), and thin (or fat) clients

17:06
<Guest89884>
ok, than it's fat-clients with chroot
17:07
great, in my further research I just thought about to ask how to find this out ^^
17:10
well I knew about fat-clients, but not about the implementation

17:20
<Guest89884>
second question after where to put .desktop-file is, do I have to rebuild the chroot after doing so?
17:30
<alkisg>
Guest89884: so, you have to put the .desktop file to /opt/ltsp/i386/etc/xdg/autostart if you want it automatically started on login
17:30
Also, when joining IRC, it's best to come up with a nickname, so that we recognize you in the future and continue from the last chat
17:30
So, type /nick your-nick-name
17:31
Select something rare that isn't registered by others
17:37
<Guest89884>
ok, thank you so much!
17:37
do I have to rebuild than?
17:37Guest89884 is now known as jeremaier
17:37
<alkisg>
ltsp-update-image
17:38
I.e. you need to recompress the chroot with ltsp-update-image, not rebuild it with ltsp-build-client
17:39
<jeremaier>
but could I use rebuild, too?
17:39
my friend make a script which I usually use
17:40
<alkisg>
If you rebuild, then /opt/ltsp/i386 is regenerated, so your /opt/ltsp/i386/etc/xdg/autostart changes are lost
17:40
It doesn't make sense to rebuild
17:41
If you want to make things easier for you, and depending on your use case, you might want to take at look at ltsp-pnp:
17:41
!ltsp-pnp
17:41
<ltsp>
ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
17:41
<alkisg>
Then you don't have to get used to ltsp chroots as you won't be using one
17:42
<jeremaier>
ok thanks for the hint
17:42
I tink for now I have to rebuild, now I understand why my changes always disappear
17:43
and where to put when I want to rebuild?
17:44
<alkisg>
I didn't understand what you're asking, could you rephrase it or explain it more?
17:45
<jeremaier>
uhm I never used the ltsp-commands by myself. but the way my friend installed it, there is a script that always rebuilds the image (and makes a backup copy and a developing surrounding)
17:46
so that's why my .desktop-files got lost all the time, as I understand now
17:46
and where can I put them, so that the rebuild process includes them?
17:47
<alkisg>
How can we know what the script does and where to put them?
17:47
It's a custom script, we can't guess what your friend did there
17:47
Normally, ltsp-build-client regenerates everything, so you can't add things automatically after that
17:48
<jeremaier>
and regenerates out of what? I thought that I have to put my files there. do I make sense?
17:48
<alkisg>
From the internet
17:49
ltsp-build-client gets the configuration from a small file at /etc/ltsp/ltsp-build-client.conf, and the packages from the internet
17:49
It doesn't get any other local files that you may have somewhere in your disk.
17:49
If it does, it's a local script that only you and your friend know about, no other ltsp users do that
17:50
<jeremaier>
ok, thank you, you are really helping me in understanding. I'll have a look at the script once again
17:50
<vagrantc>
ltsp-build-client should only be run once, to build the image
17:50
ltsp-update-image is run after you've made changes to the image
17:51
<alkisg>
jeremaier: it's possible that your friend didn't understand ltsp well, so you'll be learning the *wrong* way to do things
17:51
So it might be better to start from scratch, then follow his instructions
17:51
If you describe your use case, we might be able to help there
17:51
*than, not then
17:54
<jeremaier>
you're probably right - well I think his mistake was first of all to say 'rebuild' but meaning 'recompress' because in the script he uses 'ltsp-update-image'
17:55
you helped me a lot, I will try this again
17:55
<vagrantc>
you could also paste the script somewhere ...
17:56
<alkisg>
!pastebin

17:59
<jeremaier>
oh that's so kind! I think I should try what you told me, first, before wasting your time
18:04
But one last question before my next attempt: the application is a java app started through a script ( no need to install). where would you place the app folder, also in /opt/ltsp/i386/ - and then which subfolder? Every user should autostart it.
18:05
<alkisg>
Are the files there read-only, or the users also need write access there?
18:07
<jeremaier>
have to admit that I am not sure about that
18:08
<alkisg>
Try it without ltsp, put it somewhere where you don't have write access and run it
18:08
Or check the file dates there to see if they were recently written to
18:09
<jeremaier>
ah ok, will do that. I guess read-only, as I know it stores user-settings into homes
18:10
no I checked date, probably no changes made by my usage
18:11
so it's read-only!
18:11
<alkisg>
You could put it anywhere you want then, e.g. /opt/ltsp/i386/usr/share/<program>, or /opt/ltsp/i386/opt/<program>... it's not related to ltsp, you can read the file system hierarchy standard for more details
18:13
<jeremaier>
I will try that now
18:13
ok alkisg, thank you very, very much! I really lost at least 1,5 days by trying on my own until now... really frustrating when you know it's just a small that thing that you don't know.
18:13
I owe you a beer or any beverage you like, I would say!
18:14
