j'ai un petit soucis avec mon serveur ltsp
02:02
<highvoltage>
feel free to ask. might be a while since someone answers (most people in europe are sleeping atm and about to in the americas)
02:03
<superman>
quand je lance mon client leger plusieurs erreur apparaisse du genre "negociation error server close connection via plan A
02:03
<IAssBurger>
I fixed the time issue on my fat client by simply setting NTP_SERVER=TRUE in the conf
02:03
yeeee
02:07
<superman>
my client launches busybox. the error are: negotiation error server closed connection via Plan A
02:08
and 2nd error is failled to connect to NBD server
02:09
an idea ?
02:14
<highvoltage>
superman: you could check /etc/inetd.conf and check if the nbd entries are in there, you can also telnet to the nbd port on that host (it's usually 2000) to check that it's running
02:15
superman: you could also check /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default, I've had it before that it specifies the wrong port
02:16
(I'm really tired and need to get some sleep, but leave details about your operating system and which versions you're running, someone is sure to be able to help you with that problem)
02:17
<superman>
thank you I look at it right away
02:20
<IAssBurger>
hey on the ndb server make sure the ports are open in iptables if you have iptables installed
02:20
and make sure your /etc/exports file is setup properly
02:21
I had similar errors last night and it was because iptables was blocking some critical ports
02:22
I believe there was more than just port 2000 that I had to open
02:22
<superman>
how to make sure it does not block the port?
02:22
<IAssBurger>
also need to make sure your ssh server is listening on the server interface if your clients are relying on ssh based authentication
02:23
well do you have iptables installed?
02:23
do "aptitude search iptables" if aptitude isnt installed apt-get install aptitude, of course thats how I do it
02:23
if its installed itll show an i next to it
02:23
if its not installed itll have a p next to it
02:24
or just
02:24
iptables --help
02:24
lol

08:44
btw. has any of you tried this opensuse kiwi-ltsp project lately?
08:46
<IAssBurger>
Mava Mudkips
08:47
:)
08:48
<Mava>
mmh, was just wondering that how is it going on and can we find it reasonable good when considering usability
09:00
<Hyperbyte>
Mava, there's not a lot of kiwi-ltsp users here, afaik. There's a #kiwi-ltsp IRC channel on Freenode.
09:05
Good morning by the way, everyone. :-)
09:06
<Mava>
hehe, good morning to you too =) and thanks for info
09:06
<cyberorg>
Mava, you can find it reasonably good :)
09:07
<Hyperbyte>
cyberorg, is kiwi-ltsp much different from regular ltsp?
09:07
<cyberorg>
Mava, get the latest openSUSE Edu iso to try from here: http://sourceforge.net/projects/opensuse-edu/
09:08
Hyperbyte, only the way image are built, ltsp, ldm, ltspfs are same as upstream
09:08
we get a lot of features that comes with kiwi
09:09
<Mava>
it would be worth to try and see do I get a kick out of it
09:09
still it wont be any huge problem to pump it as virtualized
09:10
<Hyperbyte>
cyberorg, kiwi has extra features on top of ltsp?
09:10
<cyberorg>
Mava, you can boot up iso in a VM and set up server in there for testing
09:10
<Mava>
yah
09:10
<cyberorg>
follow http://en.opensuse.org/SDB:LTSP_quick_start_12.1_Edu
09:12
Hyperbyte, lots, http://en.opensuse.org/Portal:KIWI-LTSP/Featured_article
09:13
apart from aoe, now multiple image is supported with nbd as well
09:15
<Hyperbyte>
You could create multiple mountpoints with NFS easily as well, couldn't you?
09:16
<cyberorg>
Hyperbyte, other than that openSUSE uses clicfs, fuse based, so no squashfs, aufs, unionfs, bind mounts etc needed
09:18
Mava, iso is live OS, with everything needed for ltsp already installed
09:21
<Hyperbyte>
cyberorg, that sounds pretty nice alltogether actually... why isn't it more popular?
09:22
Or is OpenSUSE just not that popular?
09:23
<cyberorg>
Hyperbyte, may be that or positively everything works out of the box so no one comes here ;)
09:24
<Hyperbyte>
cyberorg, people come here not because Ubuntu LTSP doesn't work out of the box, but because they dive in without understanding how it should work and then starting messing around. :-)
09:26
So I don't really buy that argument. :P Still, kiwi-ltsp seems very nice.
09:32
<Mava>
very likely opensuse itself is not that popular nowdays, the ubuntu is the main stream so naturally everyone wants to have ubuntu with lts

alkisg, I sent a mail to ltsp-discuss few hours ago. Do these things need to be approved, or does it usually take a while, or.... ?
14:56
<alkisg>
Hyperbyte: plain text or html too?
14:56
(although I think that even html messages are now allowed automatically....)
14:56
I usually takes less than an hour to be delivered
14:56
<Hyperbyte>
I think my mail client sends both html as plain text, but prefers plain text.
14:56
<alkisg>
*it
14:56
<Hyperbyte>
Hrm...
14:57
Well the "few hours ago" is greatly exagerrated
14:57
<alkisg>
At some point, manual approval was required for mails with an html part
14:57
<Hyperbyte>
It feels that way though, but it's been 30 minutes.
14:57
Slow day....
14:57
<alkisg>
So they were received even weeks later
14:57
OK, 30 mins is not too much for sourceforge :)
14:57
Better wait a bit more

15:06
<alkisg>
hfranco1: sure, just create a login script that does whatever you want, it's not LTSP-related
15:06
You can e.g. put it in /etc/xdg/autostart
15:07

15:08
<alkisg>
Hyperbyte: just got your mail
15:09
<JesseC>
I'm just curious on how this works exactly. You simply setup the "fat client" to pxe boot and it pulls the set image down from the ltsp server correct?
15:09
<hfranco1>
thanks alkisg. i'll try that

JesseC: fatclients: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
15:10
<JesseC>
I read all of that.
15:10
but it didn't answer my question. ;(
15:10
<alkisg>
Well, fat clients are ltsp clients
15:10
So if you read the other docs about nfs and nbd you should have answered your question
15:11
In short, yes, a fat client pxe boots and uses a networked disk
15:11
Usually nbd or nfs, and authenticates to the server and uses sshfs (or nfs) for his home dir
15:11
One read only image serves any number of clients
15:11
<JesseC>
great!

Feel free to modify any wiki pages you think need fixing
15:14

15:14risca has joined IRC (risca!~risca@wi-secure-3639.cc.umanitoba.ca)
15:15
<JesseC>
alkisg: I'm not sure yet. I need a linux based thin client that support spice, and there are no major vendors that do.
15:15
I've attempted to modify thier software to add spice, but it never fully works like it should.

15:16
<JesseC>
So probably a stripped down version of ubuntu.
15:16
Ram is much much cheaper than disk on module.
15:16
<alkisg>
JesseC: if you only need one or some local applications, maybe you don't need fat clients but localapps
15:16
I.e. you install a thin ubuntu chroot and then install any local program you want on top of it
15:17
Doesn't spice come with a method for client booting?
15:17
<JesseC>
It does, but I'm using it with a virtual provider that requires going through a website to initiate the session.
15:18
So I have to at the least provide spice/iceweasel
15:18zevlag has joined IRC (zevlag!~zevlag@intranetgateway.etv.net)
15:18
<JesseC>
my thinking is the thin client will also be much faster having everything loaded into ram
15:18
as well as cheaper because of not needing any storage on it
15:18
and being able to change the image by just rebooting the thin client
15:19
<alkisg>
Thin vs fat aren't much different from the ltsp prespective, all have network disks, all can run apps locally, all don't need local disks
15:19
There's thin, localapps, remoteapps, and fat in the mix
15:19
<JesseC>
well I also dont want to put any strain on the server because it will be running a pretty dense population of virtual machines
15:20
with the fat client, I plan on modifying it so that the home directory doesn't reside on the server
15:20
but loads on the "fat client" as well
15:20
albiet read-only
15:20
if thats even possible, I should say
15:20
<alkisg>
Errmmm I have some objections or remarks there but anyway do a start and you can ask later on for the details
15:21
<JesseC>
I'm open to any remarks and objects. ;)
15:24
<zevlag>
Is there a way for me take a physical booted ubuntu machine and convert it's drive to LTSP Fat chroot image or whatever? I'm just finindg it difficult to make changes and customizations in just the chroot, I'm not getting X running etc...
15:25
<alkisg>
zevlag: just install 12.04 ubuntu precise
15:25
I just committed fixes to support just that
15:26
<zevlag>
hmm, where do I find 12.04....
15:26
<alkisg>
Google for download ubuntu 12.04
15:26
Then install it to a normal machine, and when you're done install ltsp-client
15:26
<JesseC>
zevlag: what version of ubuntu are you running at the moment?
15:27
<zevlag>
I was going to build it on 10.04 LTS
15:27
<JesseC>
zevlag: https://help.ubuntu.com/community/PreciseUpgrades
15:27
There is a guide on how to directly upgrade from 10.04 LTS to 12.04 LTS
15:27
<zevlag>
great

<zevlag>
So, for a LTSP server, I'm running Fat Clients, amd I better to run Desktop or Server install for LTSP?
15:33
Or use the altrnate CD and choose LTSP?
15:36
<alkisg>
Desktop
15:37
<zevlag>
Just so I can learn, why?
15:39
<alkisg>
Less to download
15:39
bbl
15:39
<zevlag>
thanks, ttyl
15:40
<alkisg>
(you can also use the server cd for the server itself, as it doesn't need X for fat clients only)
15:40
(but for the client the desktop is better, as it's a normal os installation)
15:41
<JesseC>
hmm
15:43
Is it possible to boot something such as crunchbang
15:43
with the ltsp server being ubuntu headless?
15:44
I see the option during the client setup to choose, but can't seem to find a list of supported distros
15:46
scratch that, I got it. ;)
15:46
<zevlag>
JesseC, I was curious baout the same thing a while ago
15:46
can you elaborate what you figured out

is there a fat client howto? and would it be an appropriate setup if the client only use rdesktop?
15:57
<JesseC>
||cw: https://help.ubuntu.com/community/UbuntuLTSP/FatClients
15:57
I don't think a fat client setup is going to give you much
15:57
if you're just using rdesktop
15:58
and nothing is really needed locally on the thin client as far as resources
15:58
most cheap linux thin clients even come with rdesktop built in
15:59
<||cw>
I'm using old pc's. also, the main use case is wireless clients
16:00
hoping for a way to centrally manage that part
16:00
<JesseC>
ah gotcha
16:00
that guide should help you out as far as getting it all setup then
16:01
me and zevlag are still trying to find out what other distros you can load though
16:02
<||cw>
I think I've seen this, seems to be missing a way to support thin and fat from same server, or am I assume things?
16:02
<JesseC>
its' there, sec
16:02
it even lets you set it to automatically choose
16:02
based on the ram available on the thin client
16:02
<||cw>
interesting, so low ram goes fat?
16:02
<JesseC>
based on the amount you choose
16:03
the low ram machines would run as thin clients
16:03
<||cw>
ah, since fat have more room for localapps
16:03
<JesseC>
and nything above the threshold would automatically load as a fat client
16:03
I just gotta find where I read it again.
16:04
Here we go, its on that same guides page at the bottom
16:04
<||cw>
and for updating the fat clients with new images, what does that?
16:04
<JesseC>
search for FAT_RAM_THRESHOLD
16:04
all on that same page, I haven't actually created my first image yet
16:05
as I'm trying to find a way to load something like crunchbang as my image
16:05
instead of ubuntu
16:06
<zevlag>
||cw, fat clients get a new image when they reboot, they still don't have a hard drive
16:07
<||cw>
so basically I'm stuck manging a local install for wireless
16:07
<JesseC>
well
16:08
you can configure the image you use
16:08
to install the needed drivers and such
16:08
before you deploy it
16:08
they just might have to click on the network and type the password
16:08
after each reboot
16:08
<||cw>
guess I was thinking fat client meant it got an hdd image, as apposed to "centrally managed locally running"
16:08
<JesseC>
nah, all runs in RAM
16:08
<||cw>
yeah that's not gonna happen
16:08
<JesseC>
and mounts its home directory on the server
16:09
you might be able to write a script that runs when it boots up
16:09
to connect to the wireless network
16:09
just need to install the needed drivers, make sure you can connect manually
16:09
<||cw>
sure, but it's gotta boot from an hdd
16:09
<JesseC>
ah
16:09
<||cw>
can't pxe boot on wifi
16:09
<JesseC>
oh yeah thats right
16:09
forgot
16:10
<||cw>
actually there is one card that allows it, but it's rare and so expensive
16:10
the card itself joins the wifi at boot, which is pretty damned slick
16:11
<zevlag>
https://help.ubuntu.com/community/UbuntuLTSP/LTSPBootingClientsWithoutPxe
16:11
<alkisg>
||cw: you can easily boot from a local kernel and a *remote* network disk like nbd or nfs
16:11
The main problem you might bump into is that wireless is not good enough for many clients
16:12
<||cw>
rdesktop works ok
16:12
<alkisg>
rdesktop and x2go are good options, yes
16:12
But not X or VNC
16:12
<||cw>
had some driver issues with this card, newer kernel and dropping back to WEP helped
16:12
right
16:12
<zevlag>
||cw, that link I sent you explains how to boot LTSP witohout LTSP
16:12

<JesseC>
alkisg: do you know where to get the options for --fat-client-desktop
16:13
<alkisg>
JesseC: distro/version? 10.04, 12.04?
16:13
<JesseC>
It simply says ubuntu-desktop, ebuntu-desktop, among others
16:14
10.04 is what I'm running
16:14
searching isn't turning anything up for me, neither is man or --extra-help
16:14
<alkisg>
Then ubuntu-desktop, edubuntu-desktop, kubuntu-desktop, and maybe xubuntu-desktop. lubuntu-desktop is probably broken on 10.04
16:14
All work on 12.04.
16:14
<JesseC>
so you can't load external distros such as crunchbang?
16:15
<alkisg>
The distro needs to have the ltsp-client package in order to use ltsp
16:15
See the irc topic for distros that do have that
16:16
<JesseC>
I mean, running ltsp-server on ubuntu 10.04, your limits for client images are all going to be ubuntu based
16:17
<alkisg>
2 years ago (in the 10.04 frame) ubuntu was pretty much the only distro supporting ltsp fat clients
16:17
Now, most distros in the topic should be pretty much compatible
16:17
So any fat chroot can connect to any other distro's ltsp server
16:18
<JesseC>
I'm not seeing anything about distros in the topic
16:18
haha
16:18

<alkisg>
The topic for #ltsp is: LTSP-5 is the current version that you should be using. Check out Ubuntu, Debian and Fedora for awesome integration. Gentoo is getting very close and Opensuse has kiwi-ltsp. IRC logs at: http://irclogs.ltsp.org, LTSP Docs: http://docs.ltsp.org
16:20
<JesseC>
Oh, I was looking for a link
16:20
not the mentioning of those 3 distros
16:20
sorry
16:20
<alkisg>
5
16:20
Not 3
16:21
<JesseC>
Hmm
16:22
<alkisg>
So if crunchbang is using the debian repositories, it's possible that it has the ltsp-client package

16:37
<ogra_>
heh
16:38
<alkisg>
lubuntu is using considerably less ram than xubuntu. But of course with 1+ gb ram there's no need to search for a light distro...
16:46
<knipwim>
to mount an ltsp nbd image, do you have to have the loop module on the client?
16:47
in other words, what command do i have to simulate to troubleshoot?
16:47
the nbd-client 192.168.0.1 2000 /dev/nbd0 works
16:48
but mount -t squashfs /dev/nbd0 /mnt/test doesn't work
16:49
<ogra_>
do you have squashfs loaded ?
16:50
(cat /proc/filesystems)
16:51
<knipwim>
yep
16:51
<Llama_be>
knipwim: I had to edit the quickstart profile like this to get it to build correctly: http://pastebin.com/EZVJJxbU
16:51
is that a bug, and should I file it as such somewhere?
16:52
<alkisg>
knipwim: blkid => shows /dev/nbd0 as squashfs
16:52
mount /dev/nbd0 /mnt =>mounts it
16:52
No loop or -t required
16:52
Also, nbd-client <params> => shows negotiation size etc, watch that it is valid
16:53
And "unknown partition" is usually displayed after a couple of seconds by udev rules
16:53
<knipwim>
oke, it can't read superblock
16:54
the server says Read failed: Inappropriate ioctl for device
16:54
<alkisg>
You're exporting a file, not a dir, right?
16:54
<knipwim>
nbd_server[1792]: connect from 192.168.0.11, assigned file is /opt/ltsp-images/ltsp-dev-i686.img
16:54
<alkisg>
And the nbd process has read rights to that file
16:54
?
16:55
<knipwim>
ehm
16:55
<alkisg>
(in case it doesn't run as root etc etc)
16:56
<knipwim>
also not working for mode 777 on the image

17:04
<knipwim>
ah, i see
17:05
the file i posted doesn't work until 5.3
17:05
and the problems are fixed there
17:06
so, yes
17:06
it's a bug
17:06
<Llama_be>
should I install 5.3? My install is not yet live yet, so currently it's just a playground for me :)
17:07
<knipwim>
if you like to play, yes
17:07
but i could also provide a patch for 5.2.19
17:07
<alkisg>
knipwim, if you don't mind installing nbd-client on the server itself, you could run modprobe nbd; nbd-client <params> there...
17:08
<knipwim>
alkisg: what would i test in that case?
17:09
<alkisg>
That there's no networking/firewall problem involved or incompatible nbd client/server versions...
17:09
<knipwim>
hmm, no nbd-client kernel support :(
17:10
on the server
17:10
<alkisg>
You could also export any file with nbd and just run md5sum on it
17:10
No need for it to be btrfs, it can be a plain text file
17:10
<JesseC>
alkisg: Doesn't it load the entire OS into RAM? If the distro is a ~4GB install, then you would need the same in ram correct? Or is part of the OS also mounted over the network for fat clients?
17:10
<alkisg>
JesseC: no, imagine booting from a usb disk of 1 Tb
17:10
Do you need 1 Tb ram?
17:10
<Llama_be>
knipwim: it's currently a playground, but it should go into "production" in the (not so very distant) future
17:11
<alkisg>
JesseC: NBD and NFS are network file systems, the client fetches the disk "sectors" that it needs when it needs them, it doesn't download the whole image
17:11
So it doesn't make any difference, speed or RAM -wise, if your image is 200 MB or 200 Gb.
17:11
<JesseC>
I see
17:12
<knipwim>
Llama_be: my intentention is to move 5.3 to stable very soon
17:12
<JesseC>
Thanks for all your help and patience alkisg. Gonna go pxe boot this machine now and give it a go.
17:12
<knipwim>
Llama_be: because the USE flag maintanance is much more simple
17:12
<Llama_be>
ok, then it's better for me to start using 5.3 so I can help you track down bugs ;)
17:13
<alkisg>
JesseC: ok, make sure to read the docs at _some_ point :)
17:13
<knipwim>
Llama_be: some reading: http://wiki.gentoo.org/wiki/LTSP#Portage_Profile
17:13
and http://wiki.gentoo.org/wiki/LTSP#5.3_Client
17:13
<JesseC>
alkisg: I do! I'm just in rapid mode right now, trying to please a client and your help is invaluable. =p
17:14
<knipwim>
Llama_be: also, i can recommend watching the wiki page for any changes
17:14
if anything changes in functionality, i'll document it there
17:15
<Llama_be>
ok. And should I encounter bugs, should it just go in the bugtracker in the one large bug for ltsp?
17:17
<knipwim>
yeah. if it's gentoo specific
17:17
otherwise in:
17:17

is it practical to have 1 big bug entry for all of ltsp in the gentoo bugtracker?

17:26
<knipwim>
perhaps backup your quickstart.profile, but etc-update will also work
17:26
you should have ltsp-server-5.3.5 btw
17:27
<Llama_be>
that's what it says it's going to upgrade to :)
17:27
but with a download of 0kb and no other dependencies?
17:27
<knipwim>
nice, and withhout X and pulseaudio :)
17:28
<Llama_be>
[ebuild U ~] net-misc/ltsp-server-5.3.5 [5.2.19] USE="dhcp nfs -X -doc -examples -nbd -pulseaudio" 0 kB [1]
17:28
<knipwim>
it's pulling from the upstream bzr branch, so no size can be calculated
17:29
and no new dependencies since 5.2
17:29
<Llama_be>
ok, that was a quick upgrade, took maybe 5 seconds :)
17:29
<knipwim>
and some postinst to read :)
17:30
you'll see separate 5.2 and 5.3 installer profiles in /etc/ltsp/profiles/.
17:31
and also, each profile refers to the /var/lib/layman/ltsp/profiles/ ltsp profile for
17:31
with specific environment settings for an ltsp chroot
17:32
<Llama_be>
I'll just also delete my chroots and start over, to be sure :)
17:32
<knipwim>
the 5.2 install is basically the same as you had
17:32
or backup if you're not entiry sure
17:33
<Llama_be>
it's a playground, backing up is not something to do there ;)
17:33
<knipwim>
going to the supermarket, leave you're questions, i'll read them later \
17:33
<Llama_be>
and which is better, quickstart or kicktoo?
17:34
<knipwim>
quickstart isn't maintained anymore
17:34
on the long run i'll probably move to kicktoo only
17:34
but i'll keep supporting quickstart profiles for a looong time
17:34
<Llama_be>
ok, then I'll use kicktoo... It will take a while to build, but I'm going too, going to do some sports :)
17:35
will talk to you later should anything come up
17:35

Ok, so how does one go about use the new feature in 12.04 to create a chroot image from a live ubuntu machine?
18:48
<alkisg>
Just install ltsp-client and copy the whole disk to your server
18:48
Will you be using a VM, or a real client?
18:48
<zevlag>
right now it's a real client, in the future, VM's
18:49
<alkisg>
(remember that you need 2 installations now, one for server and one for client)
18:49
<zevlag>
*nod*
18:49
<alkisg>
VM's are easier to copy, but it's just a copying, nothing too difficult
18:49
You just need ltsp-client on the client, copy, and run ltsp-update-image
18:50
(and ltsp-update-sshkeys before ltsp-update-image)
18:50
If you export the client disk with nfs or nbd you can even do it on the fly, without copying first
18:50
<zevlag>
cool
18:53
<alkisg>
Another easy way to test is to install the server to partition1 and the client to partition2 of the same disk, and then just export partition2 with nbd
18:53
No need for copying or running ltsp-update-image in that case

19:51
<IAssBurger>
w/e ima ssh into the client and watch my syslogs to see whats going on
19:51
so when it locks again
19:51
I can try to figure out why
19:51
but its a hard lock wehn it happens, no keyboard lights or anything
19:51
<knipwim>
the bugreport tells me it's a known bug

IAssBurger: if you mind your language a bit, more people will be inclined to help you
19:52
<IAssBurger>
mmhmm
19:52
<alkisg>
And again, you shouldn't be using gdm
19:52
<IAssBurger>
wtf
19:52
u want me to remove GDM from my server??
19:53
im not going to do that
19:53
<alkisg>
OK, I won't help you anymore until you mind your language
19:53
<IAssBurger>
well if your going to be a proper asshole about things, I dont want your help
19:53
since apparently your fragile sensibilities are easily offended
19:53
<alkisg>
You already had a problem with Hyperbyte the other day
19:54
Calling people cunts isn't going to get you help
19:54
<IAssBurger>
if you find the phrase "wtf" offensive
19:54
maybe you shouldnt irc
19:54
<highvoltage>
IAssBurger: alkisg really isn't an asshole
19:54
<alkisg>
4 years in here, you're the first person to insist on using such language
19:54
<IAssBurger>
complaining about someone using the term "wtf" makes you an asshol
19:54
<alkisg>
Maybe *you* shouldn't be using irc.
19:54
<knipwim>
well IAssBurger, this channel is rather civilized
19:54
<IAssBurger>
complaining about someone using the term "wtf" makes you an asshole
19:54
<highvoltage>
IAssBurger: I suggest you reread your text and think about how others could perceive it
19:54

dont be an asshole
19:55
Im sure there is something in the terms about being an asshole

Anyway, back to work...
19:55* vagrantc wants to make IPAPPEND 2 the default pxelinux menu option
19:55
<alkisg>
vagrantc++
19:55
<vagrantc>
it shouldn't hurt anything, and can definitely help.
19:56
presuming my patches to initramfs-tools still work...
19:56

The udhcpc ubuntu script does take BOOTIF into consideration

<vagrantc>
yes, it should.
19:58
every day, i am more and more convinced we need to re-write network boot menu configuration from scratch.
19:59
there might be some code we can re-use, but it needs to be redesigned.
19:59
i even lost some sleep one night scheming how it could/should work.
20:00
<alkisg>
I wonder if we could stop requesting a new lease, by using IPAPPEND 3 in the initramfs, and dhclient --renew-the-lease-somehow from init-ltsp.d
20:01
pxelinux tries to find a way to pass the pxe lease to initramfs, afaik
20:01
I think I read something about it in the syslinux mailing lists...
20:01
<vagrantc>
that would be cool.
20:03
alkisg: ssvncviewer, eh?
20:03
<alkisg>
vagrantc: well, stgraber insisted on 24bpp :P
20:04
I'd like to switch to ssvncviewer or xtightvncviewer completely, but they don't support disabling the f8 menu
20:04
And we don't want students to just quit the broadcast from there :)
20:04
<vagrantc>
alkisg: i saw that fotis got rid of zenity in at least one place ... but it's still used in several others...
20:05
<alkisg>
Ah, indeed, thanks, we should reuse the code server-side too
20:06
...although we're also using it for remote support notifications... hmm....
20:06
<vagrantc>
we could fork ldm-dialog...
20:06
or make it it's own package/source package

No we don't need it anymore for dialogs, just for systray icons
20:08
But if we redesign the remote assistance dialog, we could get rid of it there too
20:09
We just need a method to inform the user about (1) that we're trying to connect to a technician pc to get help, (2) about that the connection was successful, and (3) a way to end the connection
20:09
Maybe all those could be in a dialog instead of a systray icon, which doesn't show up in gnome3 anyway...
20:11
<vagrantc>
hmmm.

vagrantc: do you think the notifications about students and clients connecting/disconnecting are useful? Or should we get rid of them completely? Proper notifications are getting hard to manage with all the supported DEs and with gnome-3 etc...
20:26
<vagrantc>
alkisg: not sure i know what you're talking about ... don't have an install handy to test
20:27
i've almost exclusively used LXDE with epoptes
20:27
er, tested, i've not actually put epoptes to use yet.
20:27
<alkisg>
vagrantc: notifications like those : http://blog.resource.gr/wp-content/uploads/2009/05/ubuntu904/ubuntu-notifications.jpg
20:27
We pop up one of those for each connection/disconnection
20:28
And while at first with ubuntu's notifyosd it looked ok, and automatically closed after 10 secs etc, now it's getting a bit ugly
20:28
<vagrantc>
don't know that i've ever seen them on LXDE :)
20:28
<alkisg>
So you wouldn't miss them :D
20:28
<vagrantc>
though again, i haven't ever really used epoptes, just tested it
20:29
<alkisg>
ok
20:29
<IAssBurger>
flash is known to cause thin/thick clients to lockup
20:29
interesting

That's probably the way to find out the ID of the printer that's not autodetected
21:15
We could then put that in the .ppd file that can handle that printer with an lts.conf directive
21:17
And the ppd* commands might be useful in merging the info to the existing ppd
21:18
<srdjo>
I will try it now - It would be fine for simple use with default settings but even for printer name change we would need to modify printers.conf and the printers ppd file - but lets try this first

So I have ltsp all setup, and I have dnsmasq runnig to serve up my pxe image
21:20
but when I try to pxe boot the client, it just says image not found
21:21
however, I checked the path from a windows machine, ex. tftp 10.0.0.250 GET /ltsp/amd64/pxelinux.0
21:21
and it downloaded the file just fine
21:21
this is the same directory that I have under, /etc/dnsmasq.d/ltsp.conf
21:22
any ideas?
21:22
<alkisg>
Enable dnsmasq logging and check the logs
21:23
grep pxelinux /var/log/syslog or daemon.log etc
21:24
srdjo: for hp, the file we want to modify might be /usr/share/cups/drv/hpcups.drv (it's a text file)
21:25
<JesseC_W>
alksig: thanks once again, double 0's on the end of my pxelinux file
21:25
derp

alkisg, foomatic has command line options for ppd file generation - that is the same thing that cups uses
21:28
so we can have ppd generated by id and just copied to chroot
21:28
on boot
21:28
<alkisg>
First I'd like to find out the "correct" solution... what would cups accept to support a new printer?
21:28
E.g. there's a /usr/share/cups/drv/sample.drv file
21:28
<srdjo>
i am reading it
21:28
<alkisg>
Do they want people or vendors to ship them files like those?
21:29
If that's the "upstream" way of supporting new printers, then by following it in ltsp we encourage people to file upstream bugs to get more printers supported
21:30
If the preferred way is to use command line utilities, that's what we should use to
21:31
Did you say that you have a printer that is not automatically installed, but that you can select it from a list without downloading anything?
21:32
<srdjo>
yes I do - Samsung ML-1910
21:34
and I am currently trying to fint where does it gets the data from to generate the ppd file so I can see the id that it uses
21:39
<alkisg>
http://www.openprinting.org/printer/Samsung/Samsung-ML-1910: This printer entry was contributed by a user but was not yet verified or proofread by the site administrators. Therefore it is not included in the Foomatic packages.
21:40
...but if it's not included, where does it get the data when one selects it from the list?
