04:53 | <alkisg> !learn non-pae as To allow non-pae thin clients to boot in Ubuntu 12.04+, one can install the debian 486 kernel in the chroot: https://packages.debian.org/wheezy/linux-image-3.2.0-4-486
| |
04:53 | <ltsp> The operation succeeded.
| |
04:53 | <alkisg> urly: see above ^
| |
05:00 | <urly> hi! how to install this ?
| |
05:02 | <alkisg> How to install a .deb package? Ask in #ubuntu...
| |
05:02 | Or just google and read the first hit...
| |
05:03 | <urly> ok with .deb . then remove other kernels ? ltsp-updates-kernels ? & ?
| |
05:05 | <alkisg> No need to remove other kernels, you can leave them. You'll need ltsp-update-image.
| |
05:06 | <urly> ok. and with modules (especially sound modules) it will be ok with hardware support ? http://ubuntu.5.x6.nabble.com/PAE-server-with-no-PAE-thin-client-td5048837.html
| |
05:07 | <alkisg> It should, it's the same kernel
| |
05:08 | <urly> the same kernel than 14.04?
| |
05:08 | <alkisg> No, as 12.04
| |
05:08 | The kernel in 14.04 is about the same as in jessie, the next version of debian
| |
05:09 | I don't know if it needs a newer initramfs version than the one found in 14.04 though, that's why I'm suggesting 3.2, I've tried it with 14.04 server and non-pae clients and it worked fine

| |
05:11 | <alkisg> Yes. But if you see that, then pae is NOT your problem
| |
05:12 | With the pae problem, you don't get to see busybox, it stops before that

10:05 | ogra_ has joined IRC (ogra_!~ogra_@p5098ed03.dip0.t-ipconnect.de) | |
10:05 | <alkisg> Hello
| |
10:05 | <Ano> I'm searching for tutorials to install LTSP, I have searched some of course but they are too old or unclear
| |
10:06 | <alkisg> Which distribution are you interested in?
| |
10:06 | And, what kind of clients, thin or fat?
| |
10:07 | <Ano> The distribution of the server is Debian 7 and I'm interested in Mint Debian as Os for the thin client.
| |
10:08 | <alkisg> If it is a thin client, the client os doesn't matter
| |
10:08 | !fatclients
| |
10:08 | <ltsp> fatclients: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
| |
10:08 | <alkisg> Read the intro there to learn what an ltsp fat client is
| |
10:08 | For normal thin client ltsp, if you wanted mint for the clients, you'd install mint on the server
| |
10:09 | That's not the case for fat clients; there, you'd install mint in the chroot

| |
10:13 | <Ano> Ok, I have checked. So to reformulate : a thin client has all services on the server. A fat client has some services mounted on itself.
| |
10:13 | Is that right ?
| |
10:13 | <alkisg> Ano: most services on itself. yes.
| |
10:13 | alphabet: is that the client, or the server? I.e. did you run that on the client shell screen?
| |
10:14 | <alphabet> on the client shell
| |
10:14 | <alkisg> That doesn't seem very old... so, `less /proc/cpuinfo` there says P4?
| |
10:14 | How much RAM?
| |
10:14 | `free`
| |
10:15 | <alphabet> give me a second i need to switch from pc to pc
| |

| |

| |

| |
10:20 | <ltsp> Error: "thinclients" is not a valid command.
| |
10:20 | <alkisg> Ano: what are you client specs? RAM, CPU?
| |
10:21 | alphabet: try startx there on screen_02, does it start X?
| |
10:21 | <Ano> I'm searching that at the moment
| |
10:21 | <alkisg> alphabet: or, X -configure
| |
10:21 | <alphabet> yes it does startx and xinit both work with iceweasel that is
| |
10:22 | <alkisg> alphabet: and it only doesn't work when booted as a kiosk? and the rest of the clients boot fine? that's odd...
| |
10:22 | Put SCREEN_02=shell and SCREEN_07=kiosk etc etc, so that you have the usual boot process, AND a troubleshooting shell...
| |
10:23 | <alphabet> yeah i find it odd myself too

11:10 | <alkisg> Hi prem, ltsp-cluster isn't really maintained, debian doesn't include it, and it'll probably be removed in ltsp 6...

11:23 | <prem> alkisg, so is there any other option in ltsp to have a centralised management tool like that
| |
11:23 | <alkisg> prem: I've no idea what tools ltsp-cluster had, I've never even seen it
| |
11:24 | <prem> am looking for a good tool to manage the ltsp clients in the network., like adding new users, pxe configuration and monitoring the usage
| |
11:24 | <alkisg> ltsp-cluster had utilities to add users?!
| |
11:25 | You shouldn't need any special pxe configuration except for extreme cases
| |
11:25 | And, monitoring tools are not specific to ltsp either
| |
11:25 | So I don't think the tools you're asking for are ltsp-related...

11:29 | <alphabet> VGA compatible controller [0300] S3 unichrome pro [1106:3344]

11:29 | <alkisg> alphabet: yeah I think that's not using KMS, so it might be the reason it's working without root
| |
11:30 | Try playing with `nomodeset` in pxelinux.cfg/default
| |
11:30 | But the real fix would be to fix the kiosk code to use root in all cases...
| |
11:30 | alphabet: to make sure, boot a client that works, and run `ps` from SCREEN_02, to see if X runs as root or not
| |
11:31 | <alphabet> will do
| |
11:38 | X :7 vt7 depth runs as root on a working client
| |
11:38 | xinit and iceweasel runs as kioskuser

12:04 | <inpothet> good day
| |
12:04 | i have a question
| |
12:05 | how can i set the kernel that the clients will recive
| |
12:06 | <alkisg> Distribution/version?
| |
12:07 | <inpothet> ltsp-5 edubuntu 12.04.4.4
| |
12:07 | <alkisg> You install the kernel you want in the chroot
| |
12:08 | What is the exact problem?
| |
12:08 | <inpothet> the clients i have are non pae but the 12.04 only comes with 32 bit pae kernel
| |
12:08 | so i need to set a other kernel but im new to the ltsp system
| |
12:09 | <alkisg> Install the non-pae kernel that 12.04.1 has
| |
12:09 | sudo apt-get install linux-image-generic etc etc in the chroot
| |
12:09 | Now you have linux-image-generic-lts-backport-saucy or something...
| |
12:09 | I.e. the 12.04.4 kernel, which needs pae
| |
12:10 | <alphabet> nomodeset dind't work for me
| |
12:11 | <inpothet> can this be dont from the live disk because for some reason it wont boot after install so i can only run it from live eviroment
| |
12:12 | thanks i will try this when i get back to the server
| |
12:13 | i got notified at the last moment that he want to use ltsp because remote desktop was to laggy
| |
12:16 | alkisg does that get the kernel of the same arch or can i set it to get 32 bit
| |
12:16 | <alkisg> In Ubuntu it needs to be the same arch
| |
12:17 | You can create a 32bit chroot once you've installed it
| |
12:17 | <inpothet> ok
| |
12:18 | can i do this from live disk
| |
12:18 | <alkisg> If you have many many GBs of RAM available... sure
| |
12:18 | <inpothet> 4 gb
| |
12:19 | <alkisg> You could try it, dunno
| |
12:19 | It's surely harder than installing it to the disk
| |
12:19 | Or just boot with edubuntu 12.04.1 i386
| |
12:19 | So that you don't need to do anything

12:22 | can you mabey tell me how to make a cgroot

12:22 | *chroot
| |
12:22 | <alkisg> Download the edubuntu 12.04.1 i386 dvd and boot with that
| |
12:22 | That contains everything you need, the appropriate kernel and chroot etc
| |

| |
12:24 | <inpothet> i did
| |
12:25 | <alkisg> alphabet: in /usr/share/ltsp/*, but I can't walk you through that, it would require _me_ looking at the kiosk code... :)
| |
12:27 | <inpothet> alkisg : i can only find 12.04.2 does that work to ?

13:50 | <Ano> Halo again
| |
13:51 | <nick2_> http://pastebin.com/Be34YQrp
| |
13:51 | <Ano> I'm searching help to install thin clients with i386 on a amd64 server
| |
13:52 | Help about how to do and what is possible to do or not
| |
13:53 | <alkisg> Ano: ltsp-build-client --arch i386. But you usually don't need to do that, just install an i386 cd on your server.
| |
13:55 | <Ano> Yes but I have other services on this server and I would let it in 64x
| |
13:56 | <alkisg> OK, then use the command I wrote
| |
13:56 | <Ano> Ok
| |
13:58 | <alkisg> nick2_: did you try with only PRINTER_0_DEVICE in lts.conf?
| |
13:58 | nick2_: also, don't use 2 times the same [mac:address]
| |
13:58 | in that case, only the second one takes effect
| |
13:59 | <Ano> Then; how do I do to build ltsp client whitout using internet mirror ?
| |
14:00 | <nick2_> Ok, let my try that
| |
14:03 | my=me
| |
14:08 | <||cw> Ano: mount the cd and use --mirror file://cdrompath/{something}
| |
14:08 | I haven't tested that though
| |
14:09 | and {something} is a cdrom path that depends on the distro/version you have
| |
14:10 | <Ano> ok, is it possible to do that with a .iso ?
| |
14:10 | <||cw> mount isofilename /cdrom -o loop
| |
14:10 | <Ano> (it has to be mounted ok
| |
14:12 | <||cw> if you have an apt/sources.list file with the cdrom source in it, whatever path that has is what you'd use
| |
14:13 | <Ano> all right
| |
14:14 | <alkisg> Adding a cd doesn't also select the target architecture... it just saves a bit of bandwidth (after you've downloaded the second cd...) so you'd need --arch i386 again
| |
14:14 | <nick2_> still nothing any ideas
| |
14:14 | <alkisg> Do you have the /dev/lp device on the client?
| |
14:14 | <Ano> Yes those questions are asked to buil my ltsp-buil-client command =)
| |
14:16 | Is it during the installation that I chose the desktop and programs of the client ?
| |
14:16 | <alkisg> Ano: you've decided to use thin clients, not fat clients, right?
| |
14:17 | <nick2_> How can i check that?
| |
14:17 | <alkisg> !screen_02
| |
14:17 | <ltsp> screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
| |
14:19 | <Ano> Yes alkisg my clients do not have hard disk drive, they do not look like they could support fat config
| |
14:19 | <alkisg> Ano: fat clients don't need a hard drive
| |
14:20 | Tell us their specs like I asked you... RAM and CPU
| |
14:22 | <Ano> CPU very weak / ram 256 or 512 mega
| |
14:22 | <alkisg> OK, thin clients then
| |
14:23 | <Ano> I can't be more pecise sorry
| |
14:23 | <alkisg> So, the desktop of your clients is whatever you install on your server
| |
14:23 | <||cw> Ano: as long as the flient is capable of working with a livecd, it'll "work" as a fat client. and actually it can still work even if it doens't have enough ram to run the livecd. but whether or not it's suitable depends on what applications you want to run
| |
14:23 | <alkisg> i.e. when you install your server, not when you run ltsp-build-client
| |
14:25 | <Ano> ok if it is a thin client it will use the exact system I have on my principal server
| |
14:27 | ||cw do you mean a live cd introduced in the client ?

14:33 | <alkisg> What's the output of `ps aux|grep jetpipe` ?
| |
14:34 | <Ano> Ok because I have no cd player on my client, so definitively thin client ?
| |
14:36 | <||cw> Ano: usb boot? though if it's not a dual core cpu then thin client is almost certainly better

| |
14:38 | <alkisg> Then jetpipe is not running
| |
14:39 | (jetpipe is the daemon managing the printer)
| |
14:40 | <Ano> Yes I asked myself the question ||cw, however; clients need huge work to allow usb boot it's not possible consequently.
| |
14:43 | I have to adapt my work to the material I have. I know it's impossible to have the best LTSP configuration possible.
| |
14:48 | How does it work to install a programm for the client ?
| |
14:48 | <nick2_> Alkisg: but then how my network printers work ok? or did i screw up somewhere?
| |
14:49 | <alkisg> nick2_: network printers are accessed through the server cups, while client printers on thin clients through jetpipe
| |
14:49 | Different things
| |
14:50 | There was a bug about jetpipe not starting, check that you have all updates...
| |
14:57 | <nick2_> Is this ok : 2174 0.0 0.1 4400 792 tty2 s
| |
15:15 | <Ano> Thanks for your help today.
| |
15:15 | I wanna continue to work and come back to speak about the point I do not succeed to understant
| |
15:15 | Good bye
| |
15:15 | support rather than help by the way
| |
15:31 | <alkisg> Ano: it's like remote desktop
| |
15:32 | The clients are dumb devices that just connect to the server and run whatever programs the server has

15:45 | zamba has left IRC (zamba!marius@flage.org, Ping timeout: 250 seconds) | |
15:45 | <alkisg> Ano: if you want to follow my advice, first thing tomorrow is to come with your exact client specs
| |
15:45 | And server/network specs too
| |
15:45 | E.g. the best route might be to buy ram for the clients... or some other option... it depends
| |
15:47 | <Ano> I know those informations are very important to have good advice, I have everything about the server. I'll do my best for the clients but my only solution is to open it.
| |
15:49 | I'll find solutions for that, I need to have the minimal configuration because the only means into the budget is to buy more ram for the server may be. Depends of the price.
| |
15:49 | <alkisg> What are the server/network specs?
| |
15:49 | <Ano> old
| |
15:50 | proc : intel pentium D 3ghz, for the moment 1gb ram could upgrade to 8gb
| |
15:50 | <alkisg> That's not an appropriate server for thin clients.
| |
15:50 | How many clients?
| |
15:50 | <Ano> 4 or 5
| |
15:50 | <alkisg> Gigabit network or not?
| |
15:51 | <Ano> not the server interface
| |
15:51 | <alkisg> Check the client specs, if they're P4's you can put some RAM into them and use them as fat clients
| |
15:51 | Otherwise it's not worth it, the server is very old
| |
15:52 | <Ano> I'll speak with my boss about that.
| |
15:52 | I really have to go, thanks for the support
| |

20:00 | <alkisg> gbaman: that's probably the clients requesting nbd swap from the server, and the server not answering (not configured for swap)
| |
20:01 | <gbaman> they are NFS clients
| |
20:01 | we never did actually get round to testing NBD with the pi
| |
20:02 | <alkisg> gbaman: debian uses NFS by default for the root file system, *and* NBD for swap
| |
20:02 | Try putting this in lts.conf: NBD_SWAP=False
| |
20:02 | <gbaman> what will it use for swap then?
| |
20:02 | <alkisg> Nothing, or a local swap partition
| |
20:02 | It appears that now you haven't configured nbd swap
| |
20:03 | <gbaman> keeping in mind the oldest pis only have 256mb of ram :
| |
20:03 | :)
| |
20:03 | so NFS swap might be a good idea?
| |
20:03 | <alkisg> I'm not suggesting that you should disable swap forever
| |
20:03 | Just to verify that you currently have not configured nbd swap
| |
20:03 | <gbaman> ok, will do for test
| |
20:03 | <alkisg> And that this is indeed your issue
| |
20:04 | Then, just run `ltsp-config swap` to configure nbd swap...
| |
20:04 | Hello_ has joined IRC (Hello_!5e0b87e7@gateway/web/freenode/ip.94.11.135.231) | |
20:05 | <Hello_> Hi :) do you think an inbuilt laptop webcam can work in a thin client?
| |
20:06 | <gbaman> na alkisg, it is still sitting there
| |
20:06 | <alkisg> gbaman: you still see the connection refused message?
| |
20:06 | <gbaman> to clarify, /var/lib/tftpboot/ltsp/armhf/lts.conf
| |
20:06 | yes
| |
20:07 | the config file
| |
20:07 | http://pastebin.com/heDZPJfR
| |
20:07 | does it need to be indented?
| |
20:07 | <alkisg> No, are you use it's read from there?
| |
20:07 | Try `getltscfg -a` once it boots...
| |
20:07 | Hello_: yes, if you use localapps or fat clients
| |
20:08 | <Hello_> Nicee
| |
20:09 | <alkisg> gbaman: the 30 seconds delay is usually (1) by a wrong entry at /etc/network/interfaces, (2) by a DNS timeout, or (3) a wrong fstab entry
| |
20:09 | <gbaman> waiting for client, one sec
| |
20:09 | btw, Raspi-LTSP got a new logon screen :) https://dl.dropboxusercontent.com/u/1122948/temp/Starspi.jpg
| |
20:10 | ok, command run
| |
20:10 | no mention of nfs
| |
20:10 | so there is another one..
| |
20:11 | <alkisg> Haha nice logo
| |
20:11 | <gbaman> Raspberry Pi logo
| |
20:12 | ok, there is another lts.conf inside the armhf image
| |
20:12 | <Hello_> Fat client is ace, only thing is, i want to stop them being able to unplug the network cable and plug the internet in, would i have to build that into the distro config
| |
20:12 | <gbaman> ok, yes that was the one
| |
20:12 | rebooting now
| |
20:13 | why is there 2 lts.conf files??
| |
20:13 | <alkisg> You've probably built 2 chroots for some reason...
| |
20:13 | <gbaman> one in tftpboot
| |
20:13 | and one in the chroot
| |
20:14 | <alkisg> vagrantc likes to use the one in the chroot for NFS
| |
20:14 | ubuntu used nbd, so it couldn't use the chroot one, and moved it to tftp
| |
20:14 | Me, I want to put it in /etc/ltsp/config.d on the server :P
| |
20:15 | <gbaman> well it still sat for just as long :)
| |
20:15 | but no "connection refused"
| |
20:15 | <alkisg> OK, so that was indeed nbd swap
| |
20:15 | Now, to the delay
| |
20:16 | Check /etc/network/interfaces and /etc/fstab in the booted client
| |
20:16 | Paste them to pastebin...
| |
20:22 | <gbaman> alkisg: http://pastebin.com/vZMQHL7f
| |
20:24 | <alkisg> They seem fine, so I can only think it's DNS related
| |
20:24 | Either forward (client to server), or reverse (server can't do reverse dns on the client IP)
| |
20:25 | <gbaman> best way to test?
| |
20:26 | am guessing setting server to use 8.8.8.8 isnt going to help
| |
20:26 | <alkisg> Declare the client IPs in /etc/hosts on the server. There's some Debian.readme somewhere I think... google about ltsp reverse dns , you should find the info...

23:15 | <hermitcl> Hi all - does anyone know where window text (window title, drop-down menus inside the windows, etc) is controlled? I'm administering an 8 client network where all but 2 of the terminals have scrambled window text. Centos 6, XFCE4

23:18 | <Hyperbyte> Hi! This sounds like a #centos question
| |
23:18 | Or #xfce... LTSP just manages the network boot bit. The rest is just your distro at work.

23:18 | <hermitcl> okay - thanks Hyperbyte
