<adbenitez>
hello
15:25
can some one give some advice on where I must to put scripts to be excecuted by the thin clients? I read about /opt/ltsp/<arch>/usr/share/ldm/rc.d/ but that dir doesn't exists in my chrootless setup
15:26
<alkisg>
executed on boot as root, or on login as the user?
15:27
On boot => systemd unit. On login => /etc/xdg/autostart.
15:27
(or, INIT_COMMAND_XX for very early boot before services start)
15:28
(or, RCFILE_xx)

any links to a clean way to allow all thin clients to be able to login via ssh? when i plug in a new device it hits dhcp and gets 192.168.168.X then X=hostname and username and password. i can only log in as of now if i manually create each user (ltsp77) on the ltsp server
18:37
<alkisg>
spaced0ut: what? they already login via ssh...
18:37
ldm is using ssh as the backend
18:37
<spaced0ut>
it cant get that far
18:37
unless i create the user manually
18:37
i see the failures in auth.log
18:38
<alkisg>
spaced0ut: do you mean that you haven't been able to get ltsp towork at all?
18:38
!install
18:38
<ltsp>
install: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
18:38
<spaced0ut>
sec
18:39
<alkisg>
This is a tutorial for ubuntu, if you haven't managed to set up thin clients before...
18:39
Users are created on the server, not in the chroot etc
18:40
<spaced0ut>
So am I misunderstanding that there is a way on the server to set LDM_AUTOLOGIN=True and have clients dynamically generate machine/usernames and add them to the server?
18:41
<alkisg>
Yes, those accounts need to preexist
18:41
<spaced0ut>
wowow
18:41
<alkisg>
But, do you want a kiosk style thing?
18:41
Start with stating your specifications
18:42
<spaced0ut>
Lightweight desktop environment. Non-persistent when changes are made on the client side.
18:42
Fat clients. They'll be running browsers mainly and there will be about 200 of them so no need to put that load on the server
18:43
<alkisg>
OK, here's the workflow:
18:43
you create a single user named ltsp, with password qwer1234
18:43
You specify LDM_USERNAME=ltsp, LDM_PASSWORD=qwer1234, LDM_AUTOLOGIN=True
18:43
All that's left is to create a "local" home for the users, so that it's different for each "client"
18:44
So, on the server, you set up your /home/ltsp folder as you want it, with the light desktop environment and the browser and the setting etc etc,
18:44
then you make a squashfs image out of it, and you sent it as a template for client /home with nbd
18:44
This way the clients *think* they have a local /home/ltsp, so that you don't need multiple users, when it's actually a cow view of the image you prepared on the server
18:45
<spaced0ut>
right on
18:45
thank you so much
18:45
<alkisg>
If you want professional help in setting that up quickly, i'm available
18:46
<spaced0ut>
I'll get back to you on that monday but i think i can handle it from here.
18:46
<alkisg>
np
18:47
<spaced0ut>
in my nbd-server.conf the files are readonly
18:47
yet changes on the client side still save across reboots. i just found this out a few minutes ago and was surprised
18:47
exportname = /opt/ltsp/images/amd64.img
18:47
readonly = true
18:47
authfile = /etc/ltsp/nbd-server.allow
18:48
<alkisg>
client /home/username by default is served by sshfs, not nbd
18:48
It needs a special cow setup
18:51
<spaced0ut>
the single user is working beautifully so far. just have to tackle that part now

ugh. sorry to keep bugging you guys. i'm so close. man nbd-server has examples and when you use them theyre out of date. does anyone have an example nbd-server/conf.d/ltsp_amd64.conf file that specifies a directory being exported? does that also need to be configured on nbd-client as well? it looks like it automounts everything by default but havent confirmed
