vagrantc: got a minor issue.. OverlayFS replaces AUFS in Debian 3.18 kernel, but it has been renamed to Overlay, which in turn breaks LTSP. Suggestions?
gbaman: the code doesn't use "OverlayFS" anywhere, but it does use "overlayfs" ... so what exactly has changed?
the module name has changed?
the module is now called overlay
gbaman: sounds like we need to update the relevent code to handle that as a third option
Or it is in Debian 3.18 kernel I have been told
"have been told" ?
which has in turn been pulled and used with the Raspbian team kernels
and it is in under overlay
|00:22||* vagrantc doesn't want to write code based on heresay :)|
Might be worth talking to Plugwash when he is next about in #raspbian, we noticed this at the weekend
Assuming there was an update done, any idea how long might take to filter through?
"filter through" ?
As in, make it through into normal Debian repos
Given that usually takes a while :)
Which would in turn end up in Raspbian repos
it's not an appropriate change for Debian jessie or wheezy, so it will have to wait till after the release of Jessie.
given that the kernel in Jessie uses aufs.
What kernel version is Jessie using?
Raspberry Pi now uses 3.18
So you are saying, will be 6 months+
and even then, it won't be in raspbian jessie
|00:28||* vagrantc first wants to verify that it's a real issue|
Sounds like I will just have to edit the initramfs manually
don't edit the initramfs, use fixed scripts to generate the initramfs
Yip, that is my plan
at least rpi2 will support Debian armhf :)
But will still be using normal Raspbian for a while yet
|00:33||* vagrantc wonders if the rpi community will make any better effort at getting kernel support upstreamed properly|
would make raspbian irrelevent

wow. it's worse than I thought.
overlay in the 3.19 kernel doesn't support NFS. :(
|02:15||* vagrantc wonders if it would support NFS images...|
mounting a squashfs image over NFS is more broken due to "improvements" in the initramfs-tools NFS script...
so basically I need to fork the nfs boot script...
ok, well, NFS with a squashfs image can still work with initramfs-tools with some commandline workarounds.
well, committed and tested support for "overlay" fs to ltsp.
and figured out some workaroudns to use squashfs images on NFS...

Just made fresh install of Lubuntu 14.04. From client I can login to server with ssh, but not from LDM. No lts.conf defined, other than screens required to get shell.
muppis: when logging in from ldm, do `tail -f /var/log/auth.log` on the server, do you get a successful login?
And immediate logout.
Which desktop environment?
There's a bug in lubuntu.desktop file

Hello folks. Steve Cook here. Need some advice on how to fix the lock screen issue on pnp ltsp clients.
At the moment, if a client machine is left it locks, but then wont recognise the user password to come out of lock. The only option is to kill the session and re-log back in. i have set the clients up temorarily so that the lock is disabled....cont....
but this is not really satisfactory, so need to now how to fix it

|13:34||championofcyrodi has joined IRC (email@example.com)|
I've fopund that file you linked to. Is it a bacsh scrip and, if so, do I need to set it to run at start up. If so, is it a start up for the client or for the server or both. do i need to update the image?
sorry folks, that last set of questions is directed as alkisg
Put it in /usr/share/ldm/rc.d in your server and then run ltsp-upate-image -c /
brilliant, will do. willg et back and report in the next ten mins if you are still around

hi alkisg. Didn;t work I am afraid. Or, at least, i should add, I forced a lock screen and it wouldnlt acdept the password to come out of lock. Was that right, Or, should i have left it to go to lock scren by itself. Would that have made any difference? If not, would the solution be to do a full reinstall of a lter version of ltsp?
You can test if it worked with `su - logged-in-username`
If you're able to authenticate, then it has stored your password
You've also put LDM_HASH_PASSWORD in lts.conf, right?
What's your lts.conf like now?
I'll just go and re-check that though...hang on
|13:48||fiesh has left IRC (firstname.lastname@example.org, Quit: system reboot)|
yep, i put this in the bottom of the lts.conf yeasterday ...."LDM_PASSWORD_HASH=true"
without the quotes, of course
hang on, your hash is in a different place to mine,. does thaty make a difference?
Mine was wrong, yours is correct, but do you have correct [sections] in your lts.conf?
Can you pastebin it?
|13:53||* alkisg will be back in 30'|
|13:53||alkisg has left IRC (alkisg!~alkisg@ubuntu/member/alkisg, Remote host closed the connection)|
will do alkisg
erm....how do i pastebin folks?

okay, seems to work
|14:18||work_alkisg1 is now known as alkisg|
hi alkisg, did you get to take a gander at the script? Is it okay?
for information, the su - test one command in the terminal failed to authenticate
sorry that should have read "su - test1"
I have to dissapear for five mins, but pleased do post any advice alkisg as i will read when I return
|14:41||mikkel has left IRC (email@example.com, Quit: Leaving)|
stevecook: if the script didn't work, try a newer ltsp version
ignore that last post
okay will do alkisg

alkisg, i am just about to do a full re-write of my system. and then install the latest version of pnp LTSP. where can i get hold of that please
stevecook: it's not officially available for 14.04
It's in 15.04 etc
You can get it like you got ldm
Why do you want to reinstall your system?
glad to hear i don't. but was psychologically preparing for the possibility...! so, if I get hold of the ubuntu rust version, that should be recent enough? Addittionally, can i still follow that ubuntu titorial for installing pnp ltap or do i need to do something different given that it will be form local files
Ah nope, 15.04 still has an old ltsp, http://packages.ubuntu.com/search?keywords=ltsp-client
It appears that stgraber haven't synced it from debian
|15:23||gbaman has left IRC (email@example.com, Ping timeout: 244 seconds)|
So if you don't want to copy files like the one i told you manually, the only solution for now is debian jessie
...I think you should just keep 14.04 and try more :)
I copied that file to the relevant location like you said...and then redid the image......but it didnlt make any difference
Maybe another file is missing, you should look to backport the patch yourself
ltsp-source: at http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/files
how do i go about identifying missing files? and how to I backport a patch
I can't teach you that via irc
You might want to find someone more experienced to do that for you
I iunderstand, casn you point me to where I can learn how
Your googling is as good as mine, I can't point you on how to do a small part of being a developer...
So, the latest debian will install pnp ltsp with no screenlock issues
is that right alkisg?
Yes, although that wiki page doesn't describe what you need to do in debian
You need a few different steps there, there's a wiki page in the debian.org site for that
Also I believe that Ubuntu 16.04 will have that issue solved too
And, at some point, I might backport it for 12.04 and 14.04 as well
|15:48||Markus123 has joined IRC (Markus123firstname.lastname@example.org)|
okay, am going to install latest debian and then try and install pnp ltsp. Cheers for now alkisg. I dare say I'll be back for more advice in due course
stevecook: It's not released yet, I don't know if that matters for you
as long as wheezy has what i need, wheezy will be fine. does wheezy have the necessary?
Wheezy still has the lock screen issue?
It was only solved a few months ago
That's why it's not widespread yet
and it is as unfixable in wheezy as it is in ubuntu 14?
I don't know if you can find backports in wheezy
I don't see 5.5.4 for wheezy there
qlso, what's the difference betweem client, client core and client builder?
|15:55||Markus123 has left IRC (Markus123email@example.com, Ping timeout: 246 seconds)|
|15:55||* alkisg doesn't have more time for support for now, sorry|
Google is your friend
Keep irc for specific questions that you can't find in google...
I am bound to report, that the only reason i came here is precsiely becasue such question are rareley of ever adequately answered via a google search. i cam e hare after many weeks of just such unfroutful searches. for example......
"difference between between ltsp client, client core and client builder" has produced pages of material, but form at least the first five of whoch i have just scanned, none of them explain that difference, but simply proceed on a presumably unspoken assunption that reader already knows it
This is typical, particularly when it comes to the finer points of ltsp
This place has provided more information in a few days than many weeks of searching on the internet more brioadly
|16:00||Markus123 has joined IRC (Markus123firstname.lastname@example.org)|
Yes, but support comes at a cost of development time :)
I understand that
So if you can google about the package versions in wheezy, it saves support time ...

|16:01||alkisg is now known as work_alkisg|
|16:01||Markus123 has joined IRC (Markus123email@example.com)|
but, on the other hand, large scale take up of ltsp is only going to happen when this system is accessible by intelligent non specialists
True, but we developers don't really care about that
It's up to you to do it if you want it
We use it in our own setups, and just make it available in case others find it useful
That's open source :)
I suppose my own angle is a non specialist educationalist in the uk mainstream. I need a system that eithe rjust works, or one where the documentation takes one form a starting position of zero knowledge right up to expert
Then open source isn't right for you
Presently, there is a massive hole betweeen those two exptreme
|16:04||FrankBlues has joined IRC (FrankBluesfirstname.lastname@example.org)|
There are some open source companies that might provide what you want for a fee
I am linux though and though and have been for 5 years, so open source is for me I can assure you
And there are non-open source companies that can do that too
I can't type Greek in 14.04 because gnome + ubuntu decided that the old, working way of configuring a keyboard wasn't good enough for wayland
I tried even to send patches but they were needed in 10+ different upstreams, so I gave up
So I'm just not using 14.04 yet
In open source you have to accept that some things stay broken for a long time, or are underdocumented, or crash, or don't do what you want

|19:44||telex has left IRC (firstname.lastname@example.org, Remote host closed the connection)|
How is that question related to LTSP?
Or are you not actually talking about a boot ROM?
Hyperbyte, perhapy he wants to put LTSP client into the spare space :)
|19:46||telex has joined IRC (email@example.com)|
ogra_, putting an LTSP client directly on the chips of the network card. :-D
That'd be one hell of a fast boot though. :P
it would need to shrink a tiny bit though
Well, or bigger ROM chip size. :P
Hyperbyte: I really did mean a boot ROM.
ogra_: I was thinking more in terms of something like bootp but I suspect the machines I'd be putting them in would probably understand PXE anyway
hard to find one that doesnt have PXE support nowadays
|19:56||* lopta nods|
