| 01:57 | <superman> bonsoir
| |
| 01:59 | <highvoltage> bonsoir
| |
| 02:01 | <superman> 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

| 02:24 | vagrantc has left IRC (vagrantc!~vagrant@75-150-46-245-Oregon.hfc.comcastbusiness.net, Quit: leaving) | |

| 02:24 | <IAssBurger> deviant:/home/devadmin/source/aircrack-ng# iptables -v
| |
| 02:24 | iptables v1.4.8: no command specified
| |
| 02:24 | oh well Im no good with vmware
| |
| 02:25 | thats gunna require a special setup I am unfamiliar with, perhaps one of these other guys might be able to help

| 08:39 | <elias_a> Mava, muppis : Keskitytäänpä asiaan - let us concentrate on LTSP
| |
| 08:42 | <Mava> we should
| |
| 08:42 | and forget these weird languages o.0
| |
| 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

| 14:55 | <Hyperbyte> 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 | <JesseC> Anybody familiar with fat client setups?
| |
| 15:07 | <alkisg> !ask
| |
| 15:07 | <ltsp> alkisg: ask: Don't ask to ask a question, simply ask it, and if someone knows the answer, they'll respond. Please hang around for at least 15 minutes after asking a question, as not everybody constantly monitors the channel.
| |
| 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
| |
| 15:10 | <alkisg> !fatclients | echo JesseC:
| |
| 15:10 | <ltsp> 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!
| |
| 15:11 | <alkisg> !docs
| |
| 15:11 | <ltsp> alkisg: docs: For the most current documentation, see https://sourceforge.net/apps/mediawiki/ltsp/index.php?title=Ltsp_LtspDocumentationUpstream
| |
| 15:12 | <JesseC> I just wanted to know that single portion before I commit a ridiculous amount of hours to reading. ;)
| |
| 15:12 | Than you.
| |
| 15:12 | Thank even.
| |
| 15:12 | <alkisg> Feel free to modify any wiki pages you think need fixing
| |
| 15:14 | JesseC: which distro/version are you thinking of using?
| |
| 15:14 | risca 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.
| |
| 15:15 | komunista has left IRC (komunista!~slavko@adsl-195-168-242-217.dynamic.nextra.sk, Ping timeout: 244 seconds) | |
| 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
| |
| 15:18 | zevlag 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
| |
| 15:27 | thank you

| 15:32 | <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
| |
| 15:47 | bengoa has left IRC (bengoa!~bengoa@2001:1291:229:2:216:cbff:feab:6cc9, Remote host closed the connection) | |
| 15:47 | <JesseC> Well, I don't know if I figured it out 100%
| |
| 15:47 | but this guide seems promising
| |
| 15:47 | http://www.tuxradar.com/content/ltsp-thin-clients-made-easy
| |
| 15:48 | or not.. it doesn't have what I was looking for
| |
| 15:49 | Parker955 is now known as Parker955_Away | |
| 15:49 | <JesseC> I'll let you know if I find something else.
| |
| 15:49 | <zevlag> yeah, I just skimmed and couldn't find it

| 15:56 | <||cw> 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 | err PXE
| |
| 16:13 | <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 | checking the wiki..
| |
| 16:18 | <alkisg> type: /topic
| |
| 16:19 | <JesseC> not enough paremeters?
| |
| 16:19 | !topic
| |
| 16:19 | <ltsp> JesseC: I do not know about 'topic', but I do know about these similar topics: 'topics'
| |
| 16:19 | <alkisg> /topic, not !topic
| |
| 16:20 | What irc client are you using?!
| |
| 16:20 | <JesseC> I tried it
| |
| 16:20 | mirc
| |
| 16:20 | <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
| |
| 16:23 | superman has left IRC (superman!~superman@171.248.6.93.rev.sfr.net, Remote host closed the connection) | |
| 16:23 | <JesseC> I guess my only concern was running a full ubuntu desktop image
| |
| 16:23 | on a disless workstation with only 4gb of ram or so
| |
| 16:24 | I'll give xubuntu a go
| |
| 16:24 | <||cw> 4GB is plenty for x32. 2GB is enough
| |
| 16:25 | 1Gb is pushing it
| |
| 16:25 | <zevlag> What is the most lightweight LTSP Fat client image one could run? The only thing I want to run in mine is VirtualBox
| |
| 16:27 | <JesseC> according to that list, xubuntu ~10.04
| |
| 16:27 | and lubuntu 12.04
| |
| 16:28 | both are lightweight
| |
| 16:28 | xsl has joined IRC (xsl!~silence@unaffiliated/xsl) | |

| 16:37 | <alkisg> (06:23:41 μμ) JesseC: on a disless workstation with only 4gb of ram or so ==> only?!!
| |
| 16:37 | We're using fat clients with minimum=512 mb ram here... 1+ gb are more than enough
| |
| 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
| |
| 16:56 | Parker955_Away is now known as Parker955 | |
| 16:57 | <alkisg> And `mount -o loop /opt/ltsp-images/ltsp-dev-i686.img /mnt` on the server works fine?
| |
| 16:58 | Or, blkid /opt/ltsp-images/ltsp-dev-i686.img ==> squashfs...
| |
| 16:58 | <knipwim> Llama_be: i've added the hwdb to the gentoo profile, and also, pciutils -zlib

| |

| 17:02 | <Llama_be> knipwim: I don't know how that file is being used, but without those modifications, it would not build
| |
| 17:04 | <knipwim> Llama_be: what ltsp-server?
| |
| 17:04 | <Llama_be> [ebuild R ] net-misc/ltsp-server-5.2.19 USE="dhcp nfs -X -doc -examples -nbd -pulseaudio" 0 kB [1]
| |
| 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 | !ltsp-bugs
| |
| 17:17 | <ltsp> knipwim: I do not know about 'ltsp-bugs', but I do know about these similar topics: 'ltsp-bug'
| |
| 17:17 | <knipwim> !ltsp-bug
| |
| 17:17 | <ltsp> knipwim: ltsp-bug: To file a bug report for upstream LTSP, go to https://bugs.launchpad.net/ltsp
| |
| 17:17 | <Llama_be> is it practical to have 1 big bug entry for all of ltsp in the gentoo bugtracker?
| |
| 17:18 | <knipwim> for me it is, since i'm not a gentoo dev
| |
| 17:18 | JesseC has left IRC (JesseC!JesseCWor@wsip-98-175-20-126.br.br.cox.net, ) | |
| 17:19 | <knipwim> so new bugs won't be assigned to me
| |
| 17:24 | <Llama_be> upgrading for 5.2 to 5.3 is simply letting emerge do it's work? or might I run into problems?
| |
| 17:26 | risca has left IRC (risca!~risca@wi-secure-3639.cc.umanitoba.ca, Ping timeout: 265 seconds) | |
| 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 | <knipwim> kk
| |
| 17:35 | later
| |
| 17:35 | <Llama_be> again, thanks a lot for all your time :)

| 18:47 | <zevlag> alkisg, FYI, the nbd daemon wasn't running
| |
| 18:47 | <alkisg> Yup that's what I though
| |
| 18:47 | t
| |
| 18:47 | <zevlag> 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

| |
| 19:52 | <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 | <IAssBurger> dont be an asshole
| |
| 19:55 | Im sure there is something in the terms about being an asshole
| |
| 19:55 | <alkisg> 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 | <alkisg> The udhcpc ubuntu script does take BOOTIF into consideration
| |
| 19:56 | [GuS] has left IRC ([GuS]!~MysT@unaffiliated/gus/x-663402, Read error: Connection reset by peer) | |
| 19:58 | <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

| 20:07 | <alkisg> 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.
| |

| 20:23 | <alkisg> 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
| |
| 20:29 | <vagrantc> although i do want to demo epoptes to our education coordinator at freegeek

| 21:14 | <alkisg> srdjo: manpages.ubuntu.com/ieee1284_get_deviceid.3.html
| |
| 21:15 | 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

| 21:20 | <JesseC_W> 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

| 21:27 | <srdjo> 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?
