| 05:27 | <alkisg> Good morning. What's the correct preposition? "this software can also be installed on debian-based labs" or "in debian-based labs"?
| |
| 05:35 | <knipwim> software is installed on computers, i would say
| |
| 05:36 | perhaps this installing takes place in debian-based labs
| |
| 05:38 | <alkisg> Thanks, /me updates the epoptes.org site accordingly... :)
| |
| 05:39 | knipwim: if you ever want to do a gentoo package for epoptes, I'd be glad to help however I can :)

| 06:04 | <laurei> hi guys, i have one simple question, how do i know if I am running the thin client or fat client
| |
| 06:07 | drdata has left IRC (drdata!~drdata@pool-173-57-189-158.dllstx.fios.verizon.net) | |
| 06:08 | <alkisg> laurei: run `hostname` and see if you get the server name or e.g. ltsp123
| |
| 06:08 | <laurei> alkisg: ok, what should i look for?
| |
| 06:09 | <alkisg> laurei: how is your server called?
| |
| 06:09 | If you open a terminal on the client, you'll see your prompt like "laurei@server" or "laurei@ltsp123"
| |
| 06:09 | The first means that you're on the server, since you see your server hostname (DNS name) there
| |
| 06:10 | <laurei> oh, yes its digopolis on all my machines
| |
| 06:10 | this means its thin client?
| |
| 06:10 | <alkisg> That means you're using thin clients
| |
| 06:10 | Another way to verify it is to check for the ltsp server package: dpkg -l ltsp-server
| |
| 06:10 | <laurei> not happy, i have gigs of ram, i want a fat client, installed according to directions but didnt work
| |
| 06:10 | <alkisg> Which directions?
| |
| 06:11 | <laurei> help.ubuntu.com/community/UbuntuLTSP/LTSPFatClients
| |
| 06:11 | <alkisg> !fatclients
| |
| 06:11 | <ltsp> alkisg: fatclients: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
| |
| 06:11 | <laurei> running 11.10
| |
| 06:12 | <alkisg> The URL you just posted says: This page is specific to Ubuntu versions 7.10, 8.04, 8.10. For later versions, please read https://help.ubuntu.com/community/UbuntuLTSP/FatClients instead.
| |
| 06:12 | So, delete your chroot and follow the other page
| |
| 06:12 | <laurei> :) thankyou i'll do that
| |
| 06:13 | cant see the forest through the trees
| |
| 06:13 | <alkisg> :)
| |
| 06:13 | <laurei> oh, actually, no i just pasted the wrong url, i did install according to this
| |
| 06:14 | created a config file, seeds, and ran installer
| |
| 06:14 | <alkisg> OK, so, let's start troubleshooting
| |
| 06:14 | On your server, run: ls -l /opt/ltsp/i386/etc/ltsp_fat_chroot /opt/ltsp/images
| |
| 06:14 | What's the output?
| |
| 06:16 | <laurei> both files exist
| |
| 06:16 | is it strange that pxe points to i386.tmp?
| |
| 06:16 | <alkisg> Size of the second one?
| |
| 06:17 | If you have 2 files in images/, I'd like to know :)
| |
| 06:17 | I don't want to lose the forest :)
| |
| 06:17 | So please paste the whole output here
| |
| 06:17 | <laurei> ok i'll try get an ssh, running through teamviewer and through another xen vm manager
| |
| 06:18 | -rw-r--r-- 1 root root 37 2011-10-19 01:30 /opt/ltsp/i386/etc/ltsp_fat_chroot
| |
| 06:19 | total 545392
| |
| 06:19 | -rw -r --r-- 1 root root 558477312 2011-10-18 02:26 i386.img
| |
| 06:19 | this is all
| |
| 06:19 | <alkisg> That's not big enough to be a fat chroot
| |
| 06:20 | Let's try another way: du -sh /opt/ltsp/i386/
| |
| 06:20 | <laurei> 609 M /opt/ltsp/i386
| |
| 06:21 | <alkisg> Yes that's a tihn chroot, fat ones are a lot bigger than 1 Gb
| |
| 06:21 | Delete that chroot and follow the wiki page again, and watch for any errors
| |
| 06:21 | <laurei> so the installer had errors i think
| |
| 06:21 | yes i can check form the scrollback
| |
| 06:21 | i thought it worked because i'd already delted the i386
| |
| 06:21 | and it works

| 06:22 | shawnp0wers has left IRC (shawnp0wers!~spowers@linuxjournal/staff/shawnp0wers, Ping timeout: 255 seconds) | |
| 06:22 | <alkisg> Maybe it didn't install some of the necessary packages that would make it a fat, the errors would tell us
| |
| 06:22 | <laurei> pastebin anwyere?

| |
| 06:28 | the last line is LTSP client install ended abnormally
| |
| 06:29 | <alkisg> Run: sudo chroot /opt/ltsp/i386 apt-get install xdiagnose
| |
| 06:29 | So that we see why it doesn't want to get installed
| |
| 06:29 | <laurei> btw a brand new ubuntu alt install on xen
| |
| 06:30 | 386
| |
| 06:30 | <alkisg> It's possible that in oneiric, network-manager is an indirect ubuntu-desktop dependency, that's why it fails, the above command should tell us

| 06:33 | <laurei> some packages couldnt be installed, this may mean you requested impossible situation or if yoou'r using unstable distro taht some req. packs aren't created or have been moved from incoming. following info may help:
| |
| 06:33 | the following backs have unmet deps:
| |
| 06:33 | xdiagnose: depends: apportbutit is not installable
| |
| 06:33 | e:unable to correct probs, you have held broken packs
| |
| 06:34 | <alkisg> Continue with: sudo chroot /opt/ltsp/i386 apt-get install apport
| |
| 06:35 | <laurei> pack apport is not avail. but is referred to by another pack. missing, obsolete, or is only available from another source
| |
| 06:35 | <alkisg> Ah ok, got it
| |
| 06:36 | <laurei> e: Package 'apport' has no installation candidate
| |
| 06:36 | <alkisg> ltsp-trunk/server/plugins/ltsp-build-client/Ubuntu/030-fat-client:Package: network-manager modemmanager ubufox apport jockey-common
| |
| 06:36 | <laurei> this is a command?
| |
| 06:36 | <alkisg> The fat client plugin blacklists apport, it needs to be removed
| |
| 06:36 | No, so, here's what you need to do:
| |
| 06:36 | sudo vi /usr/share/ltsp/plugins/ltsp-build-client/Ubuntu/030-fat-client
| |
| 06:37 | In line 43 you'll see "apport" somewhere
| |
| 06:37 | Remove that word, then save the file, and delete your chroot and run ltsp-build-client again
| |
| 06:44 | * alkisg updates the wiki page... | |
| 06:44 | <laurei> its started
| |
| 06:45 | took 10 mins last time at least
| |
| 06:45 | do you think this would cause a fatal?
| |
| 06:45 | i guess it threw me because i removed the whole chroot but it started working again after the install
| |
| 06:46 | <alkisg> This this is fatal
| |
| 06:47 | OK, I updated the wiki about the Oneiric problem
| |
| 06:51 | <laurei> will my user accounts be the same in thin/fat?
| |
| 06:51 | <alkisg> Yes
| |
| 06:51 | <laurei> im just wondering how my network image scanner will cope with this
| |
| 06:52 | it has a scan to button, and not sure if it just listens or sets to a hostname
| |
| 06:53 | big wonderful world of ltsp

| 09:30 | <DawnLight> hey everyone
| |
| 09:31 | how is everyhone
| |
| 09:31 | khildin has left IRC (khildin!~khildin@ip-80-236-227-20.dsl.scarlet.be, Ping timeout: 252 seconds) | |
| 09:36 | <Hyperbyte> DawnLight, answering that question would require global telepathy.
| |
| 09:45 | <DawnLight> Hyperbyte: i'll ask the illuminati to GPL that library
| |
| 09:46 | i'm researching about the use of linux desktop sessions over the internet
| |
| 09:46 | the problem i immediately think of is video playback
| |
| 09:47 | any comments on that?
| |
| 09:47 | particularly very helpful insights
| |
| 09:48 | <alkisg> nx is a good way to have sessions over the internet
| |
| 09:48 | For video inside the session over e.g. adsl line, nothing would work, except for mounting the video file locally and playing it locally

| 09:50 | <DawnLight> how about using fat clients and "local apps"
| |
| 09:50 | alkisg: does local apps work like that?
| |
| 09:51 | <alkisg> DawnLight: start with "how do I boot LTSP over the internet"? first...
| |
| 09:51 | <DawnLight> that part would seem to at least in first thought be doable
| |
| 09:51 | <alkisg> And, even before that, "why do I need ltsp to boot over the internet"?
| |
| 09:52 | <DawnLight> yes, or at least that i would not need to
| |
| 09:52 | the bandwidth is what a bit worries me
| |
| 09:52 | <alkisg> You usually already have an OS there, right? so why would you need ltsp?
| |
| 09:52 | You can mount a dir from the ltsp server to your home, that would be something like a fat client
| |
| 09:52 | <DawnLight> well i'm not sure i need ltsp but in this channel i figured i would get some answers
| |
| 09:53 | <alkisg> True, so start by telling us what do you need. Is it remote sessions? Only remote files?
| |
| 09:53 | <DawnLight> i thougt there was a 'local apps' feature. why do you suggest mouting stuff like this
| |
| 09:53 | what i'm looking for is
| |
| 09:53 | but you have to keep it a secret
| |
| 09:53 | cloud desktop
| |
| 09:54 | <alkisg> The channels are logged in public, but don't worry, only the internet users will know
| |
| 09:54 | * Hyperbyte laughs out loud | |
| 09:54 | * Hyperbyte high fives alkisg | |
| 09:54 | * alkisg high fives back, but with closed fingers :P | |
| 09:54 | <Hyperbyte> :(
| |
| 09:54 | <alkisg> (the mountza stuff we talked the other day :D)
| |
| 09:54 | <Hyperbyte> Yes. :(
| |
| 09:54 | I remember. :(
| |
| 09:54 | * Hyperbyte sulks | |
| 09:55 | <alkisg> DawnLight: LTSP is best suited for LAN, e.g. an ADSL line doesn't suffice to boot or use LTSP clients
| |
| 09:55 | They'd go very slowly
| |
| 09:55 | <DawnLight> don't cry
| |
| 09:55 | <alkisg> What bandwidth are you thinking of?
| |
| 09:55 | 1 mbps? 20?
| |
| 09:55 | <DawnLight> ahm... i'm thinking of 100
| |
| 09:55 | down
| |
| 09:55 | <alkisg> Eh, ok, if you have 100 mbps for *each* client that's a lot
| |
| 09:56 | But I was talking about the client side
| |
| 09:56 | <DawnLight> yes
| |
| 09:56 | ogra_ has left IRC (ogra_!~ogra@p5098ed03.dip0.t-ipconnect.de, Excess Flood) | |
| 09:56 | <DawnLight> 100mbps is like... not expensive here
| |
| 09:56 | <alkisg> Well if you have 100mbps bandwidth for each client, then that's no normal internet :D You could use LTSP with that, sure
| |
| 09:56 | <DawnLight> again, the problem is video
| |
| 09:56 | <alkisg> Nope
| |
| 09:57 | With fat clients video isn't a problem
| |
| 09:57 | Or localapps etc
| |
| 09:57 | <DawnLight> oh
| |
| 09:57 | so what are you saying
| |
| 09:57 | <alkisg> Also, video isn't much of a problem with regular thin clients, with 100mbps for each
| |
| 09:57 | <DawnLight> not each
| |
| 09:57 | <alkisg> (12:55:56 μμ) alkisg: Eh, ok, if you have 100 mbps for *each* client that's a lot
| |
| 09:57 | <DawnLight> right
| |
| 09:57 | <Hyperbyte> DawnLight, let me blunt: LTSP isn't what you're looking for.
| |
| 09:57 | ogra_ has joined IRC (ogra_!~ogra@p5098ed03.dip0.t-ipconnect.de) | |
| 09:58 | <Hyperbyte> *be.. blunt
| |
| 09:58 | <DawnLight> please be
| |
| 09:58 | nx, you're suggesting?
| |
| 09:58 | <alkisg> DawnLight: so, will your clients have 100mbps connections to your server?
| |
| 09:58 | If so, ltsp is fine
| |
| 09:58 | <Hyperbyte> alkisg, his server will only have one 100mbps connection
| |
| 09:59 | <alkisg> Hyperbyte: fat clients can live with that
| |
| 09:59 | <DawnLight> how much do you think each client should have for streaming those common 480 youtubes
| |
| 09:59 | the server could have more
| |
| 09:59 | <alkisg> 1 mbps
| |
| 09:59 | <DawnLight> really
| |
| 09:59 | <alkisg> Fat clients, yes
| |
| 09:59 | Trixboxer has joined IRC (Trixboxer!~Trixboxer@office.supportdepartment.net) | |
| 09:59 | <alkisg> They'd need about 30 mb to boot
| |
| 09:59 | <DawnLight> so and the fat clients actually work seemlessly?
| |
| 09:59 | <Hyperbyte> DawnLight, doesn't matter if you have fat clients. The videos would be played locally.
| |
| 09:59 | <alkisg> Then it's just a remote file system with 100mbps speed, shared
| |
| 10:00 | <DawnLight> what? the videos are plaid locally?
| |
| 10:00 | <alkisg> Yes
| |
| 10:00 | <Hyperbyte> How are you going to PXE boot over the internet? You'd need a local DHCP server for every client, wouldn't you?
| |
| 10:00 | <alkisg> No, a cd with gpxe is fine
| |
| 10:00 | <DawnLight> you mean that the video is streamed from the streaming lets say youtube server to the CLIENT directly/

| 10:00 | <alkisg> For fat clients, yes
| |
| 10:01 | And also it may not even use your server connection to reach youtube (if you prefer that)
| |
| 10:01 | It can just take the os + /home from your server
| |
| 10:02 | Imagine booting the clients from a usb stick, and mounting /home from your server - that would be the result wrt performance
| |
| 10:02 | <DawnLight> if the firefox/flashplugin is local then why would it use the server connection to reach youtube?
| |
| 10:02 | <alkisg> (except they'd use the server nbd image instead of a usb stick)
| |
| 10:02 | It's configurable, you may want to filter things and use nat on your server to do it
| |
| 10:03 | <DawnLight> it is configurable?
| |
| 10:04 | * DawnLight sits quitely but inside is in awe of the mighty glory of god | |
| 10:05 | <alkisg> Summary: you put gpxe in a floppy, cd, usb stick, or hard disk
| |
| 10:05 | A user boots his diskless pc with that
| |
| 10:05 | It gets an ip from the local dhcp server, e.g. a router
| |
| 10:05 | Then it sets next-server=your server
| |
| 10:05 | And downloads the kernel etc from there, and mounts the nbd disk from there, etc etc
| |
| 10:05 | Then the user logs in on your server, but the apps run locally
| |
| 10:06 | <Hyperbyte> DawnLight, your 100mbit connections, do they use static of dynamic IP's?
| |
| 10:06 | <alkisg> Now, if you want to use your server as a proxy, of course you can configure that
| |
| 10:06 | <DawnLight> dynamic
| |
| 10:06 | <Hyperbyte> Okay
| |
| 10:06 | <DawnLight> the server could be behind static and have a ginormous bandwidth
| |
| 10:06 | <alkisg> And the user files are stored in your server and accessed with ssh (ldm uses that for login) for security
| |
| 10:07 | <DawnLight> and this means that constant bandwidth for the /home is use
| |
| 10:08 | at least on some use cases
| |
| 10:08 | but if it is mostly just browser stuff...
| |
| 10:08 | what about the /tmp directoy?
| |
| 10:09 | for example it would be funny if a streaming video gets streamed from the streamer like youtube to the client which is a fat client only to be stored in the /tmp on the ltsp server
| |
| 10:11 | <Hyperbyte> tmpfs on /tmp type tmpfs (rw,nosuid,nodev)
| |
| 10:11 | <DawnLight> so it is ram?
| |
| 10:11 | or what are you trying to say?
| |
| 10:12 | <Hyperbyte> http://en.wikipedia.org/wiki/Tmpfs
| |
| 10:12 | <DawnLight> i don't know how i deduced that
| |
| 10:12 | <Hyperbyte> (you deduced correctly)
| |
| 10:13 | <alkisg> You can also use local storage, if your clients have that
| |
| 10:13 | Do they?
| |
| 10:13 | <DawnLight> i'd very much like to get rid of local storage
| |
| 10:13 | <alkisg> Well then what were you planning to use instead of the server /tmp?
| |
| 10:14 | <DawnLight> i'm aiming at centralization of all resources
| |
| 10:14 | i wasn't planning i'm exploring the possibilities
| |
| 10:14 | <alkisg> Your clients will use the tmpfs, and if you provide them with (encrypted?) NBD_SWAP, they'll swap over the network in the server /tmp
| |
| 10:14 | <DawnLight> and you're helping me mucho
| |
| 10:15 | <alkisg> That should be a good plan, to use the tmpfs first and nbd_swap if the tmpfs gets full
| |
| 10:16 | <DawnLight> is there some kind of combination that would allow using the server's processing resource while still having critical stuff like videos sent to the thin clients directly?
| |
| 10:16 | or is there no need for that at all?
| |
| 10:16 | <alkisg> If your clients can play youtube videos locally, they have the cpu to run all other things too, imho
| |
| 10:17 | <DawnLight> as it would be ok to just have the video streamed once from the youtube to the server and the x session to the thin clients
| |
| 10:18 | is this a question of bandwidth only or is there something more?
| |
| 10:19 | <alkisg> That's called "localapps". I don't see any advantage with localapps vs fat clients in your case.
| |
| 10:19 | Localapps are handy for "install an app on the server, and all the clients get it instantly"
| |
| 10:19 | But they require more bandwidth because of the X traffic for the session etc
| |
| 10:20 | <DawnLight> they get it instantly anyway, don't thye?
| |
| 10:21 | i mean they are logged in to the server aren't they? or are you talking about using local apps with fat clients
| |
| 10:21 | i realize i'm making a mess

| |
| 10:43 | <andygraybeal> :))) heya
| |
| 10:43 | what'd you mess up?
| |
| 10:43 | was there a conversation going before i joined?
| |
| 10:43 | you don't have to catch me up if so
| |
| 10:44 | <alkisg> DawnLight: nope, if you have questions that weren't answered above, just ask them again
| |
| 10:52 | <DawnLight> well i was wondering since you mentioned something about 1mbps being enough... as long as clients have enough bandwidth would video playback be cool if they were completely thin clients?
| |
| 10:52 | <alkisg> It would be enough for the question you asked, not in general
| |
| 10:52 | I.e. "how much bandwidth to stream a youtube video for fat clients"
| |
| 10:53 | That's the same question as "how much bandwidth do I need to stream youtube video from youtube"
| |
| 10:53 | Video playback needs width * height * bits per pixel * frames per second
| |
| 10:54 | For 1024x768 full screen youtube video, that's about 300 mbps
| |
| 10:54 | Xvideo is more conservative, it needs video width * video height * 12 bpp * frames per second
| |
| 10:54 | For a divx video, that's about 50 mbps
| |
| 10:55 | But flash doesn't use xvideo
| |
| 10:55 | Also you need to take into account your latency, not only your bandwidth
| |
| 10:55 | Latency shows much more on X sessions (thin clients) than on disk access (fat clients or localapps)

| 10:57 | khildin has joined IRC (khildin!~khildin@ip-80-236-227-20.dsl.scarlet.be) | |
| 10:57 | <DawnLight> so if i want decent video in multiple ltsp clients i won't be opting for completely thin clients - can i deduce that?
| |
| 10:58 | considering we're talking about over-the-internet-ltsp
| |
| 10:58 | or over-the-internet-x-session
| |
| 10:58 | or not x session
| |
| 10:59 | <alkisg> Yes, you can deduce that

| |
| 12:39 | <alkisg> Did you download gpxe?
| |
| 12:39 | <DawnLight> will do
| |
| 12:40 | i didn't know where to start
| |
| 12:40 | and which ports to open on the server
| |
| 12:40 | and the whole process i'd like to understand
| |
| 12:40 | <alkisg> DawnLight: use google translate on this forum post: http://alkisg.mysch.gr/steki/index.php?topic=1451.msg24373#msg24373
| |
| 12:40 | First install ltsp locally, to understand how it works
| |
| 12:40 | Then you'll open the necessary ports and use gpxe like I say above
| |
| 12:41 | <DawnLight> i've done ltsp over lan before there's nothing much only the dhcp server to configure
| |
| 12:41 | and the tftp server
| |
| 12:42 | and to build the client images
| |
| 12:42 | thats about it
| |
| 12:42 | <alkisg> Right, so you're only missing the gpxe bit and the ports then
| |
| 12:42 | <DawnLight> aight thanks

| 12:53 | <laurei> strange bug! LTSP logs in perfectly fine but after it's logged in the same password doesnt work for authenticated tasks
| |
| 12:53 | on fat client
| |
| 12:54 | <alkisg> It's not a bug, it's a feature :D
| |
| 12:55 | The password is not stored in the client /etc/shadow for security purposes
| |
| 12:55 | Why would you need sudo on a fat client?
| |
| 12:55 | <laurei> i tried on the real machine to install mythtv-frontend and it worked, i rebooted a fat client and its not installed, so i decided to do it from the client
| |
| 12:56 | <alkisg> It wouldn't work from the client, it would only install it to the client RAM, not on the server disk
| |
| 12:56 | Did you run ltsp-update-image?
| |
| 12:56 | <laurei> i need to do this every time i install something?
| |
| 12:56 | <alkisg> !ltsp-update-image
| |
| 12:56 | <ltsp> alkisg: ltsp-update-image: If you use NBD (e.g. Ubuntu), every time you change something in your chroot (e.g. /opt/ltsp/i386), you need to run ltsp-update-image and reboot the thin clients for the changes to take effect
| |
| 12:57 | <alkisg> So yes, unless you switch to NFS (which is slower)
| |
| 12:57 | <laurei> oh sweet, thanks, doing admin tasks from real machine is fine for me, just a gotcha. i'll update image

| 13:05 | <laurei> how would i do admin tasks eg install software that needs gui configuration
| |
| 13:05 | from a vendor package
| |
| 13:08 | <alkisg> Unfortunately chroots and X and dbus and gconf and other services don't mix well
| |
| 13:09 | If you absolutely have to, you could bind-mount the server /proc, /dev etc in the chroot, and run xhost + in your server, and then launch the app inside the chroot
| |
| 13:10 | Or you could expose your chroot via NFS, read-write, and netboot a single client over that
| |
| 13:10 | * _UsUrPeR_ tips his hat | |
| 13:10 | <alkisg> You can't do it with a trivial method
| |
| 13:10 | <_UsUrPeR_> hey all. Does ltsp_localapps=true no longer work in 11.04/11.10?
| |
| 13:10 | <laurei> sounds hardcore, i just want to install printer utilitys for an all in one brother
| |
| 13:10 | <alkisg> Or you could wait until fat clients support booting a chroot via virtualbox :)
| |
| 13:10 | <Hyperbyte> Hi Joel. :)
| |
| 13:11 | <_UsUrPeR_> helloooo
| |
| 13:11 | <alkisg> Hi _UsUrPeR_
| |
| 13:11 | <Hyperbyte> I believe it's LOCALAPPS=True, not LTSP_LOCALAPPS
| |
| 13:11 | And it's True by default, so wouldn't have any effect anyways.
| |
| 13:12 | Localapps worked out of the box for me in 11.04, if that's what you're wondering about.
| |
| 13:12 | It's even LOCAL_APPS, according to the manpage, by the way.
| |
| 13:13 | And according to the manpage it's defaulting to false as well.
| |
| 13:13 | I stand corrected.
| |
| 13:13 | !lts.conf
| |
| 13:13 | <ltsp> Hyperbyte: lts.conf: http://manpages.ubuntu.com/lts.conf
| |
| 13:15 | <alkisg> Hyperbyte: no, don't stand, sit down again and read the man page again
| |
| 13:16 | It mentions localapps 2 times, I belive
| |
| 13:16 | The first time it says it's false, the second true
| |
| 13:16 | The true part is true :P
| |

| |
| 14:33 | on a fat client
| |
| 14:35 | <alkisg> laurei: on a fat client, it's simple. On a fat chroot, it's not.
| |
| 14:37 | <laurei> so if i use a client i can sudo and install software enjoyed by everyone?
| |
| 14:37 | <alkisg> No
| |
| 14:37 | <laurei> im going to cry
| |
| 14:37 | <alkisg> They'd be installed in the tmpfs and lost on reboot
| |
| 14:37 | <laurei> ok
| |
| 14:37 | <alkisg> I told you from the start, the answer is no :)
| |
| 14:38 | You either need to go ..hardcore, or need to wait until we implement an easy method
| |
| 14:38 | ...maybe a couple of years, if the others agree :)
| |
| 14:38 | <laurei> almost every package i need installed uses some front end config tool
| |
| 14:39 | whats the simplest hardcore method :P
| |
| 14:39 | <alkisg> Maybe exporting your chroot with nfs rw for a single client
| |
| 14:39 | I don't know of any docs about either method
| |
| 14:42 | <laurei> nfs export chroot would seem a general enough linux concept if i guess right
| |
| 14:49 | <Gadi> what are you installing that has a front end config tool for system files? usually those gui front ends modify the user's homedir

| 20:38 | <markit> hi alkisg, I need help :)
| |
| 20:39 | I'm in the lab for the Linux Day
| |
| 20:39 | I'm trying to setup a certain screen resolution for a client
| |
| 20:39 | but seems to ignore the settings
| |
| 20:39 | I've in /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 20:39 | [01:00:02:A5:FC:B1:B5]
| |
| 20:39 | X_MODE_0=800x600
| |
| 20:40 | but ldm screen is in full resolution, and the monitor is stressed and could break
| |
| 20:40 | btw, anyone who knows the answer is welcomed :)
| |
| 20:41 | <alkisg> markit: put XRANDR_MODE_0=800x600 instead
| |
| 20:41 | <markit> also I've some random problems in the server, probably due to irq conflicts, right now I can't move the mouse anymore
| |
| 20:41 | <alkisg> markit: also, you have too many numbers there
| |
| 20:41 | A mac address only has 6 bytes
| |
| 20:41 | Remove the 01: in front
| |
| 20:42 | <markit> thanks
| |
| 20:42 | I'll try
| |
| 20:43 | kubuntu splash screen during boot
| |
| 20:43 | then "invalid card number"
| |
| 20:44 | (splash was at high res)
| |
| 20:44 | I've also put XSERVER=vesa
| |
| 20:44 | <alkisg> markit: do you have sch-scripts running on that lab?
| |
| 20:44 | *epoptes
| |
| 20:45 | <markit> yep
| |
| 20:45 | but can't use mouse, and I'm not that good with keyboard
| |
| 20:45 | <alkisg> After invalid card number, did LDM appear?
| |
| 20:45 | <markit> no
| |
| 20:46 | (before worked, then balck screen with invalid card, now instead black and invalid before ldm)
| |
| 20:46 | (ldm did not appeared)
| |
| 20:46 | hope this server troubles are due to the additional network card.. I do hate these problems
| |
| 20:46 | <alkisg> markit: remove any lts.conf entries that you have for that client
| |
| 20:46 | <markit> ok
| |
| 20:46 | <alkisg> Reboot the client, and check if ldm runs
| |
| 20:46 | <markit> remove or just #?
| |
| 20:47 | <alkisg> #
| |
| 20:47 | But also the XSERVER part
| |
| 20:48 | <markit> ok, ldm now
| |
| 20:48 | (probably at 1280x1024)
| |
| 20:48 | <alkisg> OK, but no mouse on the server?
| |
| 20:48 | <markit> no :(
| |
| 20:49 | I've epoptes started now
| |
| 20:49 | <alkisg> Hmmm it'll be difficult to use epoptes then :D
| |
| 20:49 | <markit> hehehe, hope phantomas will fix ;P
| |
| 20:49 | <alkisg> OK, do another try:
| |
| 20:49 | <markit> mmm no pc show in epoptes
| |
| 20:50 | <alkisg> Now put XRANDR_MODE_0=1024x768 under [Default]
| |
| 20:50 | <markit> I could reboot the server and login again
| |
| 20:50 | ok
| |
| 20:50 | <alkisg> So that it surely affects the client
| |
| 20:50 | And reboot the client
| |
| 20:50 | <markit> clever
| |
| 20:51 | <alkisg> (11:49:45 μμ) markit: mmm no pc show in epoptes => did you install epoptes-client in the chroot?
| |
| 20:51 | <markit> I've no memory, but the test before worked
| |
| 20:52 | I was able to see it... just really don't remember of having installed it but seems is there
| |
| 20:52 | (only broadcast teacher screen did not worked)
| |
| 20:52 | <alkisg> Even if you don't install it, you can see the clients after they login
| |
| 20:52 | <markit> (but was able to see thumbails and run vinagre)
| |
| 20:52 | <alkisg> But if you install it in the chroot, you can also see them before login
| |
| 20:52 | <markit> ah
| |
| 20:52 | so I've NOT installed in chroot
| |
| 20:52 | <alkisg> And now this client didn't login, that's why you didn't see it
| |
| 20:52 | Right
| |
| 20:53 | <markit> it's 800x60 as I set in [default]

| 20:53 | brunolambert has left IRC (brunolambert!~brunolamb@nat/revolutionlinux/x-wixzoyoujytnawys, Ping timeout: 256 seconds) | |

| |
| 20:53 | let me check lease file
| |
| 20:53 | <alkisg> markit: it's also possible that it didn't like XSERVER=vesa
| |
| 20:54 | Try again to put that mac address, you can see it from epoptes with right click => properties
| |
| 20:54 | (after you reboot your server to get your mouse back :))
| |
| 20:55 | hughessd has left IRC (hughessd!~hughessd@173-164-117-109-Oregon.hfc.comcastbusiness.net, Quit: hughessd) | |
| 20:55 | <markit> I was not able to see mac , do I have to install client in chroot for that also?
| |
| 20:55 | <alkisg> Yeah :(
| |
| 20:55 | <markit> I'ìve mac UPPERCASE, is it ok?
| |
| 20:55 | <alkisg> It's ok
| |
| 20:56 | <markit> seems to me to remember has to be uppercase
| |
| 20:56 | <alkisg> I think it's case insensitive
| |
| 20:57 | <markit> well, don't ask me why, now works
| |
| 20:57 | thanks very very much!!!
| |
| 20:57 | your help is invaluable
| |
| 20:58 | <alkisg> np
| |
| 21:02 | <markit> btw, is the "card number" a synthom of a different problem?
| |
| 21:02 | also I've one pc whith lcd that seems with the correct resolution, but after a while screen becomes black and you only have the mouse cursor
| |
| 21:03 | <alkisg> Yes, it's an unrelated warning, I read a bug about it somewhere...
| |
| 21:03 | <markit> I'm shocked that this brand new asus MB can't be expanded with additional nic without IRQ conflicts (it has fortunatly 2 on board)
| |
| 21:03 | <alkisg> For the LCD screen, try adding nomodeset in pxelinux.cfg/default
| |
| 21:04 | <markit> ehm, never heard of that settings, can be done "per client" base?
| |
| 21:04 | <alkisg> Yes, but try it from the global file first, it's easier
| |
| 21:04 | !pxelinux.cfg
| |
| 21:04 | <ltsp> alkisg: Error: "pxelinux.cfg" is not a valid command.
| |
| 21:04 | <alkisg> !nomodeset
| |
| 21:04 | <ltsp> alkisg: nomodeset: Unfortunately, Kernel Mode Setting (KMS) doesn't work well with some cards. To disable it, open /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default and replace "quiet splash" with "nomodeset".
| |
| 21:04 | <markit> I can't take notes with copy and paste now, hope a log will be produced by konversation
| |
| 21:05 | interesting
| |
| 21:06 | ok, the client with the (now) lower resolution now has black screen and "invalid card number"
| |
| 21:06 | <alkisg> You mean after the nomodeset change?
| |
| 21:07 | <markit> no, not tried
| |
| 21:07 | <alkisg> It worked before, right? When did it break?
| |
| 21:07 | <markit> no, never worked
| |
| 21:07 | <alkisg> (11:57:31 μμ) markit: well, don't ask me why, now works
| |
| 21:07 | <markit> before I had worse troubles with modem res, and I thought that black screen was due to that
| |
| 21:07 | <alkisg> Were you talking about a different PC there?
| |
| 21:07 | <markit> yep, works = lowe resolution
| |
| 21:07 | I've tried to lowe the resolution in vain
| |
| 21:08 | but still, after some time
| |
| 21:08 | (some minutes, while chatting with you)
| |
| 21:08 | become black with teh "no card number" error
| |
| 21:08 | Steve_the_Pirate has left IRC (Steve_the_Pirate!~Gary@cpc16-haye17-2-0-cust169.haye.cable.virginmedia.com, Quit: Leaving) | |
| 21:08 | <markit> so in any case, the too high resolution was not good for the CTR monitor, but was not the cause of "no card number", I think
| |
| 21:09 | <alkisg> Ignore the "no card number" warning, it's not significant
| |
| 21:09 | <markit> ah
| |
| 21:09 | <alkisg> OK take a step back. Are we always talking about just 1 pc?
| |
| 21:09 | <markit> yes
| |
| 21:09 | <alkisg> (12:02:44 πμ) markit: also I've one pc whith lcd that seems with the correct resolution, but after a while screen becomes black and you only have the mouse cursor
| |
| 21:09 | ^ still one pc there?
| |
| 21:09 | <markit> is another one, but I did not talked about it
| |
| 21:10 | just that note you mention
| |
| 21:10 | <alkisg> So they have the same problem, no?
| |
| 21:10 | <markit> so forget about it
| |
| 21:10 | probably yes
| |
| 21:10 | same hardware also
| |
| 21:10 | <alkisg> OK, which graphics card do they have?
| |
| 21:10 | <markit> only different monitor
| |
| 21:10 | <alkisg> (do you have a mouse now?)
| |
| 21:10 | <markit> I've no idea
| |
| 21:10 | no
| |
| 21:10 | letì's reboot the server :)

| 23:02 | <kusznir> Hi all: I've got an ubuntu 10.10 ltsp server I'm trying to commission, but having trouble getting my thin clients to boot (DevonIT). They appear to start booting, then after the tftp screen,t he display goes black (not asleep, just black) and remains that way. I never get an ability to get a console or anything.
| |
| 23:02 | I don't even know how to troubleshoot this as I don't get any debugging output or the opportunity to turn any on...
| |
| 23:11 | pr0d has joined IRC (pr0d!~prod@host86-143-74-202.range86-143.btcentralplus.com) | |
| 23:13 | <pr0d> Can i ask ubuntu LTSP questions in here?
| |
| 23:13 | <kusznir> Yes
| |
| 23:14 | You may need to stick around for a while to get them answered, though. I don't think many of the "experts" are active at this moment.
| |
| 23:14 | <pr0d> Hmm
| |
| 23:14 | * kusznir is not an expert, but an "experienced user" | |
| 23:14 | <pr0d> Well my client is booting to login screen but im getting error "No response from server, restarting..." when i try to log in
| |
| 23:15 | tryed the only google result i got and didnt help
| |
| 23:16 | <kusznir> That error can mean a number of things.
| |
| 23:16 | <pr0d> I thought you might say that
| |
| 23:16 | <kusznir> Generally, you get that when a login is not successful.
| |
| 23:17 | <pr0d> cant login as root either
| |
| 23:17 | <kusznir> Reasons for failure include: 1) unable to reach the server; 2) server's ssh key is unknown; 3) username/password incorrect; 4) server-side user account is incorrectly or incompletely created.
| |
| 23:17 | Can you log in as that user at the server?
| |
| 23:17 | <pr0d> yes
| |
| 23:17 | could be ssh keys
| |
| 23:17 | <kusznir> Is your server also the ltsp netboot server for your thin clients (eg, one server does it all)?

| 23:18 | <pr0d> yes
| |
| 23:20 | <kusznir> I have my thin clients set up so that I can alt-F2 into a shell. i don't remember if that's default, or if I had to specially config that. But I'd recommend turnning that on and assigning a local root password to the thin client. Then, try logging into the thin client itself via the text login and ssh as the user in question to the server and see what you get.
| |
| 23:21 | <pr0d> when i drop into shell ctrl+alt+f1 i cant login with my server creds, what user should i login as?
| |
| 23:21 | <kusznir> The root account you previously created :)
| |
| 23:22 | <pr0d> Hmm i never created a root account
| |
| 23:22 | <kusznir> Log in as root on your server; chroot /opt/ltsp/i386; run passwd and set a password; exit; ltsp-update-image
| |
| 23:22 | Then reboot your thin client and try to log in as root.
| |
| 23:22 | <pr0d> i see
| |
| 23:23 | <kusznir> Any time you want to change something that lives on the thin clients, you've got to do it in /opt/ltsp/i386. then when you're done making changes, run ltsp-update-image. When that finishes, you can reboot thin clients to get the new image.
| |
| 23:25 | <pr0d> Ok thats starting to make sense, never worked with computers in this way before
| |
| 23:26 | thanx for your help :)
| |
| 23:26 | <kusznir> no problem

| 23:29 | <vagrantc> pr0d: most likely your ip address changed and you need to run ltsp-update-sshkeys followed by ltsp-update-image
| |
| 23:29 | instead of setting a root password in the image, just use SCREEN_02=shell
| |
| 23:29 | in lts.conf
| |
| 23:35 | <pr0d> Brilliant, all working now :)
| |
| 23:35 | tyvm :)
| |
| 23:42 | <kusznir> Ok, so I did more troubleshooting. I managed to turn off the quiet boot, and saw what was going on. The kernel boots fine, and then when it starts X, it appears to crash. The screen does go black, but I can't change VTs either.
| |
| 23:43 | I tried running ltsp-install-client on my 10.10 machine to install a natty image, and set all this again, but ran into the same problem.
| |
| 23:44 | Potentially relevent facts in this case: my ltsp-server is a xen VM that is dedicated soley to running the disk image for the thin clients. There's no X on that VM. I have two other VMs that are thin client terminal servers, both ubuntu (different versions).
| |
| 23:44 | Origionally I had copied the ssh keys over and did the update-keys; the natty version doesn't have that yet. However, before that's an issue, I have to get the thin clients to boot up to an ldm login.
| |
| 23:44 | Any suggestions?
