<gbaman>
vagrantc: You about?
19:18
<AustriaBound>
Absolutely enjoying my first experience with Linux and LTSP. Love the Ubuntu flavor of dist, but wondering how difficult it would be to build a mint flavor. I've tried with a custom lts.conf file but didn't work for me.
19:18ben_nabiy is now known as bennabiy
19:18
<vagrantc>
gbaman: somewhat
19:18
<bennabiy>
!mint17
19:18
<ltsp`>
mint17: ppa:bennabiy/testing contains updated packages which are already patched for mint 17.
19:19
<gbaman>
vagrantc: how possible would getting the server IP from proxy DHCP be for pis?
19:19
<bennabiy>
AustriaBound: If you either manually update your files with the changes made upstream, or just install your ltsp files from my ppa, you will have mint support
19:20
<vagrantc>
gbaman: how are you getting DHCP now?
19:21
<gbaman>
Does it not get an IP when it starts booting?
19:21
*the client
19:21
<vagrantc>
gbaman: basically, you'd have to get your DHCP client to support it.
19:21
which is probably non-trivial
19:22
<gbaman>
hmm
19:22
<bennabiy>
AustriaBound: if you are trying to build it on an Ubuntu machine, you might be hit and miss. You might just need to do --mint-dist qiana --dist trusty after you update your plugins
19:22
<gbaman>
would certainly make things a lot more stupidly simple
19:22
<vagrantc>
gbaman: you're still loading the kernel and initrd off of SD, yes?
19:23
<gbaman>
yip
19:23
<bennabiy>
vagrantc: did you get any more response about pushing on getting LTSP6 going?
19:23
<vagrantc>
i only think genuine PXE implementations support proxyDHCP, but i could be wrong.
19:23
<AustriaBound>
bennabiy: I've looked through some of the code and it looks like it is trying to copy the repositories. So a "ltsp-build-client --arch amd64 --mint-dist qiana" would work?
19:23
<vagrantc>
bennabiy: just sbalneav and i planning on being around fo the 5th-10th to put some solid time into it
19:23
<bennabiy>
Well, you might need to patch your plugin a little if you do not have a mint server
19:24
AustriaBound: ^
19:24
<AustriaBound>
bennabiy: That might have been the problem. I was building everything on a headless Ubuntu server.
19:24
<bennabiy>
vagrantc: I cannot be around the whole time, but I will see what I can do.
19:25
AustriaBound: It would be a simple change to add the mirror to the script
19:25
rather than copy it
19:25
<AustriaBound>
I'll give that a try.
19:26
<bennabiy>
If you need the mirror info, I can pastebin it
19:26* bennabiy runs only on mint :)
19:26
<AustriaBound>
That would be great.
19:28
I've got a 50 client network as a working prototype. Looking to convince the school and neighboring schools to adopt LTSP. Any plans for paid support? Schools like that.
19:35
<vagrantc>
nothing "official"

19:37gbaman has joined IRC (gbaman!~gbaman@host81-130-113-138.in-addr.btopenworld.com)
19:39
<AustriaBound>
One thing I would like to work on in the short term is random login themes. I've had the students design a few and would like to randomize them each session. Is the lts.conf file loaded each session start or just on boot?
19:40
<vagrantc>
just on boot
19:40
typically
19:40
there are probably hooks you could drop that could update LDM_THEME= on reload
19:42
<AustriaBound>
I'll let you know of our progress.
19:43
Also wondering if it could be possible to boot to a menu that would allow for loading of multiple images? So could the pxeconfig file switch directories for images? or is it fixed?
19:44
<vagrantc>
yes, you can create a menu that can boot different images
19:45
ideally all the images would be hosted on the same server, as you need the kernel + initrd from each image
19:45
<AustriaBound>
That would be just too cool. Once I get my mint image up I'll make that happen.
19:45
Same server, same home directory, same ldap. Would be a great demo for some IT departments.
19:46
<gbaman>
vagrantc: you got any uboot experience?
19:47
<AustriaBound>
Nope. This marks my 4th month with Linux.
19:48
Couldn't more excited though. Converted all my students over and not going back. I'm jealous for all experience you all have.
19:53
vagrantc: By the way, I was able to get my scripts working. I now have creation of new users after server authentication from LDAP. The benefit is that I do not have caching service or pam_mkhomedir.so on the server which means I do not have duplicate users and directories.
19:53
All home directories are on the remote NFS server.
19:53
Thanks for your help.
20:02
<gbaman>
as vagrantc, I might now have uboot working...
20:07
<vagrantc>
gbaman: well, i've only been working on the next upload of u-boot to debian for the last week or so... :)
20:08
been working more on u-boot packaging than ltsp lately, actually
20:08
<gbaman>
well thats convenient..
20:08
seeing as I know nothing about it :)
20:08
<vagrantc>
AustriaBound: that sounds really nice
20:09
<gbaman>
and am blindly playing with it
20:09
so expect some questions in a few mins :)
20:09
<vagrantc>
gbaman: i had u-boot working, but the video resolution was horrible
20:09
gbaman: on the rpi
20:09Phantomas1 has left IRC (Phantomas1!~phantomas@ubuntu/member/phantomas, Remote host closed the connection)
20:10
<gbaman>
I have yet to ever get it working properly before
20:11
<AustriaBound>
If I had students ( or myself ) interested in to contributing to the development. Where would be the best starting place?
20:12
<gbaman>
*Cough* Documentation *Cough*
20:12
:)
20:12
<AustriaBound>
That is very true.
20:13
Ok. I'll ask for volunteers in the morning.
20:13
<gbaman>
:)
20:15
I could be wrong (and vagrantc is better to ask) but a huge amount of LTSP documentation is out of date
20:15
so work on it would be amazing
20:16
<AustriaBound>
I have several students looking for a project. They want more coding, but documentation is just as important.
20:16
<gbaman>
I have spent the past month doing documentation, an important skill to work on
20:17
the key thing with documentation though is they have to actually try it to see if it works
20:19
<AustriaBound>
I've got a lab. It's pretty amazing. Working on getting it documented. Not going to impress NASA, but it consists of several Atom CPU servers. Those servers are the only machines with hard drives in them. So 23 servers and 50 clients are running on ~350 watts of server power.
20:19
<gbaman>
not too shabby :)
20:20
<AustriaBound>
Clients are AMD moblie units that consume under 20 watts. Performance is great. Most of the power savings is due to LTSP.
20:20
They can try it out, makes sure it works, then document it.
20:22
I see the .pdf and the html file in the repository. Is that where they would need to start or the wiki?
20:22
<gbaman>
also a graphical interface for configuration and management would be nice..
20:22
similar to sch-scripts...
20:22
<AustriaBound>
I've got one started with one student.
20:22
<gbaman>
but not in greek...
20:22
<AustriaBound>
Writes lts.conf files.
20:23
<gbaman>
you may want to point him towards my project for ideas if he is bored at some point http://gbaman.github.io/RaspberryPi-LTSP/
20:23
LTSP for use with Raspberry Pis
20:23
But with a full control panel
20:24
2000+ lines of bash...
20:24
<AustriaBound>
Nice. We have some BeagleBone Blacks we want to use for that as well.
20:24
<gbaman>
and the new documentation site - http://pi-ltsp.net/index.html
20:24
<AustriaBound>
Very very nice.
20:25
<gbaman>
designed for teachers with 0 linux experience
20:25
so everything must be extremely simple
20:25
still work in progress though
20:26
with only 5-10 schools currently using it
20:26
anyways, brb
20:27
<AustriaBound>
I've got a good group of about 5 students that are ready for some great projects. LTSP is a great one.
20:37
<Hyperbyte>
Why is pi-ltsp.net not integrated in wiki.ltsp.org?
20:37
Or even in the regular LTSP codebase?
20:38
<gbaman>
back
20:39
Hyperbyte: because it is technically a separate project. Trying to keep it apart as the documentation is for teachers. Don't want them getting confused by the rest of the normal LTSP documentation if you get where i am coming from?
20:40
plus, Raspi-LTSP does not actually work (currently) with anything else other than Pis :)
20:40
is extremely heavily customised
20:42
problem being I *just about* have enough time to work on Raspi-LTSP :(

22:49

(thank goodness for UART)
22:50

22:50
vagrantc: look familiar by any chance? :)
22:52
<vagrantc>
heh
22:53
<gbaman>
not sure how to actually script it though..
22:53
(or how to fix video)
22:53
<vagrantc>
the way i had it set up was to download a bootscript over the network...
22:54
my mind is foggy with how i did it with the rpi ... it's certainy the weirdest board of them all.
22:54
<gbaman>
don't get uboot though... It isnt just a bash script...
22:54
I can't just seem to put a bash script on the tftp server and point it using uenv file...
22:54
as I get "unknown comand: setenv"
23:07
vagrantc: going to call it a day
23:07
might give it a go tomorrow evening
