| 01:46 | <Guest10205> hello
| |
| 01:46 | <muppis> Hello.
| |
| 01:46 | <Guest10205> can anyone help me?
| |
| 01:46 | I have a problem booting via etherboot an ltsp ubuntu 10.04 version
| |
| 01:47 | pxe boot is working, but I need etherboot
| |
| 01:47 | I get a bunch of dots.....done and after that nothing happens
| |
| 01:48 | someone suggested to install mknbi on the server and tsp-update-kernels, but no luck yet
| |
| 01:48 | any ideas?

| 02:03 | <Guest10205> anyone here with etherboot experience?

| 02:10 | <muppis> Guest10205, I think most of those still sleeps. :/
| |
| 02:12 | <Guest10205> ooh, at least someone
| |
| 02:12 | just installed this new version ltsp and can not boot my client
| |
| 02:12 | <muppis> Yep, but I don't have any experience from etherboot. :(
| |
| 02:13 | <Guest10205> understand
| |
| 02:13 | <muppis> I've been lucky getting everything working with PXE.
| |
| 02:14 | <Guest10205> that works here too, but I need etherboot as well
| |
| 02:14 | dobber has joined #ltsp | |
| 02:15 | <Guest10205> do you know what is the difference between ltsp-update-image and ltsp-update-kernels ?
| |
| 02:17 | <muppis> Guest10205, if I remember correctly, -image rebuilds only imagefile from chroot. -kernels updates files under /var/lib/tftboot/ltsp/
| |
| 02:18 | <sweetpi> -image recreates the nbd image, -kernels updates your tftp environment
| |
| 02:18 | <Guest10205> oh, thx
| |
| 02:18 | <sweetpi> ^ what he said
| |
| 02:19 | <Guest10205> i need to wait then until someone here can help with booting via etherboot
| |
| 02:20 | <sweetpi> you just need to set the path to pxelinux, there are examples iirc on the wiki
| |
| 02:21 | <Guest10205> where is that? please?
| |
| 02:21 | btw, pxe boot is fine, but I need etherboot
| |
| 02:22 | <sweetpi> what dhcp server?
| |
| 02:25 | alkisg has joined #ltsp | |
| 02:25 | <Guest10205> i am on ubuntu 10.04
| |
| 02:25 | <sweetpi> actually, what problems are you having? I dont remember any special setup except where your fetching gpxe and then trying to boot normally
| |
| 02:26 | <Guest10205> problem is: boot starts and after a bunch of ......done nothing happens
| |
| 02:27 | normal mainboard-based pxe is booting fine
| |
| 02:27 | but for some machines I need etherboot
| |
| 02:29 | <sweetpi> there shouldnt be any special setup iirc, check logs. however, etherboot will use REAL pxe, so if you have a dhcp server that supports it, make sure its also configured or the boot will fail

| 02:30 | <sweetpi> dnsmasq usually causes that problem when its only setup to send a boot filename

| |
| 02:31 | <Guest10205> ooh gusy this is above my level, I neew some kind of step-by-step to fix this

| 03:09 | <Guest10205> etherboot anyone else?
| |
| 03:10 | <Appiah> what dns server are you using?
| |
| 03:10 | when you use etherboot(same as gpxe right) you can debug and see what options your client is reciving
| |
| 03:10 | maybe need to add an option
| |
| 03:11 | <Guest10205> appiah: can you give me more detail?
| |
| 03:11 | i am using this method: http://etherboot.anadex.de/
| |
| 03:12 | the image is booted from a hdd
| |
| 03:12 | <Appiah> no I never used etherboot
| |
| 03:12 | <Guest10205> all if fine under ubuntu 8.04 ltsp
| |
| 03:12 | oh, ok, I guess then I am stuck
| |
| 03:12 | <Appiah> yupp
| |
| 03:12 | start debugging
| |
| 03:13 | that looks really old
| |
| 03:13 | http://etherboot.org/wiki/start thats more recent?
| |
| 03:14 | 2005 was the last update on the link you gave..
| |
| 03:16 | <alkisg> Guest10205: don't use anadex.de, it's ancient
| |
| 03:17 | Use gpxe instead
| |
| 03:17 | !gpxe
| |
| 03:17 | <ltspbot> alkisg: "gpxe" :: the successor to etherboot (http://etherboot.org). To download bootable floppy, cd, usb, kernel etc images, visit http://rom-o-matic.net/
| |
| 03:17 | <alkisg> You can put that on a hard disk as well
| |
| 03:19 | <Guest10205> oh, I see
| |
| 03:20 | just a sec
| |
| 03:22 | the website I mentioned (anadex.de) provided an image that had (eb-net.com) in it that I put on the hard drive to boot
| |
| 03:22 | <alkisg> You can use the usb image for that
| |
| 03:22 | <Guest10205> can I just replace the file from rom-o-matic
| |
| 03:23 | <alkisg> There are also other possibilities, e.g. if your client hard disk has ubuntu installed, you can install "grub-gpxe" which will add "boot from network" to grub,
| |
| 03:24 | <Guest10205> no, I just need something I can replace the older anadex's .com file
| |
| 03:24 | <alkisg> if they have windows, you can install ltsp-loader.exe, etc etc
| |
| 03:24 | If they don't have any os, use the usb image for gpxe
| |
| 03:24 | From rom-o-matic, and dd that to the disk
| |
| 03:25 | <Guest10205> it has an old dos/win 95 boot menu
| |
| 03:25 | and users can choose to load either an old dos porgram or to boot ltsp
| |
| 03:26 | this was done via anadex's method
| |
| 03:26 | so I am asking what do I need to replace that .com file with?
| |
| 03:26 | <alkisg> Nothing
| |
| 03:27 | If you don't want to change the clients, you can change the server
| |
| 03:27 | I think the version of etherboot that anadex uses is recent enough to support pxelinux.0
| |
| 03:27 | So
| |
| 03:27 | sudo gedit /etc/ltsp/dhcpd.conf
| |
| 03:27 | And remove that "if" that sends "nbi.img" to your clients
| |
| 03:28 | This way they'll always get pxelinux.0 and boot with no problems (afaik)
| |
| 03:28 | <muppis> alkisg, I wonder why that if -statement has put there in first place?
| |
| 03:28 | <alkisg> muppis: for older etherboot clients, in a ROM
| |
| 03:28 | Some thin clients have ancient etherboot versions in their firmware
| |
| 03:28 | <muppis> alkisg, ah.
| |
| 03:29 | <Guest10205> I would like to keep the old menu and the old dos program on the hdd so users can choose
| |
| 03:29 | <alkisg> Guest10205: ok, so edit /etc/ltsp/dhcpd.conf like I wrote above. You don't need to change your clients then.
| |
| 03:30 | I don't remember what menu anadex uses for windows 9x
| |
| 03:31 | But there are better/more recent alternatives. Well anyway you don't have to change anything in your clients.
| |
| 03:31 | Just change dhcpd.conf in your server.
| |
| 03:32 | <Guest10205> one more: if I remove the if would pxe based machines also work still?
| |
| 03:32 | <alkisg> Yes
| |
| 03:32 | <Guest10205> btw, anadex only provided an image on a .com format, then I edited my autoexec.bat to boot it
| |
| 03:33 | <alkisg> No they also had an "install to hard disk" method on their boot disk
| |
| 03:33 | But that's ancient and unsupported, so for new installations it's better to use more recent tools
| |
| 03:33 | gpxe-based

| 03:39 | <Guest10205> I undesrtand this, and sorry for my lack of undesrtanding...
| |
| 03:40 | Uzzi has joined #ltsp | |
| 03:40 | <Guest10205> I undesratnd I ndeed to use gpxe now, just one thing I am missing is that how can I boot to it from hdd?
| |
| 03:41 | and to keep my old dos program too
| |
| 03:42 | <Appiah> follow the instructions on the website
| |
| 03:43 | <Guest10205> or if I remove nbi.img from dhcp than I can keep my old anadex version to boot? I am puzzled
| |
| 03:43 | <Appiah> why dont you just start by reading the first steps?
| |
| 03:43 | and kind of , start over
| |
| 03:44 | get to know how it works
| |
| 03:44 | !gpxe

| 03:45 | <Appiah> http://etherboot.org/wiki/howtos

| |
| 03:46 | <Guest10205> thanks
| |
| 03:46 | Guest10205 has quit IRC | |
| 03:47 | Guest10205 has joined #ltsp | |
| 03:51 | <alkisg> Guest10205: *all* you need to do is change 1 line in dhcpd.conf
| |
| 03:54 | <Guest10205> like this? option root-path "/opt/ltsp/i386";
| |
| 03:54 | # if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
| |
| 03:54 | # filename "/ltsp/i386/pxelinux.0";
| |
| 03:54 | # } else {
| |
| 03:54 | # filename "/ltsp/i386/nbi.img";
| |
| 03:54 | # }
| |
| 03:54 | }
| |
| 03:55 | <alkisg> No
| |
| 03:55 | <Guest10205> commented out the lines
| |
| 03:55 | joelgsm has joined #ltsp | |
| 03:55 | <alkisg> No it doesn't send any filename at all
| |
| 03:56 | You need this uncommented: filename "/ltsp/i386/pxelinux.0";
| |
| 03:56 | Also you forgot to comment the last }
| |
| 03:59 | <Guest10205> let me try ,
| |
| 03:59 | do I have to restart the service?
| |
| 04:02 | <alkisg> Ye
| |
| 04:02 | s
| |
| 04:02 | sudo invoke-rc.d dhcp3-server restart

| 04:07 | <Guest10205> alkisg, it is now not booting the normal pxe mode since i removed that line
| |
| 04:07 | so I understand what you are trying
| |
| 04:08 | but the old anadex thing isn't booting either
| |
| 04:08 | what I need to figure out is how to put that gpxe on the hdd
| |
| 04:08 | <Appiah> did you read the page I linked you?
| |
| 04:09 | <Guest10205> etherboot.org?
| |
| 04:11 | <alkisg> Guest10205: can you paste your dhcpd.conf?
| |
| 04:12 | Maybe you still have that syntax error with the }
| |
| 04:12 | !pastebin

| |
| 04:12 | <Guest10205> ok
| |
| 04:14 | http://ltsp.pastebin.com/xsQqWuSk
| |
| 04:14 | <alkisg> Guest10205: yeah, it's completely wrong
| |
| 04:14 | Let me paste you a correct one
| |
| 04:14 | <Guest10205> ok
| |
| 04:14 | jhutchins has joined #ltsp | |
| 04:15 | <alkisg> http://ltsp.pastebin.com/im9U745v
| |
| 04:17 | <Guest10205> alkisg: so you only wan to boot the pxe
| |
| 04:17 | <alkisg> Not exactly. All will boot with pxelinux.0
| |
| 04:17 | Including your etherboot clients
| |
| 04:18 | Don't forget to restart dhcp3-server
| |
| 04:18 | <Guest10205> ok, I go and try it :)
| |
| 04:18 | <alkisg> Yup, it's about time. :)
| |
| 04:22 | <Guest10205> well, it loads the dots again, and now I get 2 more lines after ....done
| |
| 04:22 | pxe linux ... peter anvin and then stops
| |
| 04:23 | <alkisg> Hmmm maybe you don't have the latest anadex version? maybe your etherboot it's too old...
| |
| 04:23 | <Guest10205> but remeber I still have the old etherboot thing
| |
| 04:24 | Mobe_ has joined #ltsp | |
| 04:24 | Mobe has quit IRC | |
| 04:25 | <Guest10205> mine is 5.4.0 I think it is the latest
| |
| 04:25 | but ok, I am willing to replace anadex's version to gpxe if possible
| |
| 04:26 | just not sure if I can
| |
| 04:27 | <alkisg> To load linux from win98, you have some options:
| |
| 04:27 | 1) install grub (or grub4dos)
| |
| 04:27 | 2) use loadin
| |
| 04:27 | 3) use a .com file. I don't think gpxe offers one
| |
| 04:27 | So currently you're in (3) and you want to go to (1) or (2)
| |
| 04:28 | (The last etherboot is 5.4.4 afaik)
| |
| 04:30 | <Guest10205> alkisg: you are right, and many thanks for hleping
| |
| 04:34 | can you please paste this entire converation to pastebin for later use?
| |
| 04:34 | <alkisg> See the topic for the irc logs url
| |
| 04:37 | <Guest10205> oh, right,
| |
| 04:39 | alkisg: once I have either grub4dos or loadlin, what would be the concept? what do I have to achieve?
| |
| 04:39 | <alkisg> To load gpxe.lkrn
| |
| 04:39 | That's gpxe in a linux kernel format, so that grub or loadlin can load it
| |
| 04:39 | You can get that from rom-o-matic
| |
| 04:40 | E.g. for grub2:
| |
| 04:40 | menuentry "Network boot (gpxe)" {
| |
| 04:40 | linux16 /boot/gpxe.lkrn
| |
| 04:40 | }
| |
| 04:41 | <Guest10205> aha, that is a lot of help
| |
| 04:43 | i think it will be ok: https://help.ubuntu.com/community/UbuntuLTSP/grubgpxe
| |
| 04:46 | <alkisg> Yup I wrote that a couple of years ago before switching to native packages
| |
| 04:46 | But for windows 98 it's still the best option
| |
| 04:47 | <Appiah> win98 and best in the same sentence ^^
| |
| 04:47 | <Guest10205> hehe
| |
| 04:48 | i will try it to install it to my hdd and somehow keep my other dos program intact
| |
| 04:49 | in fact I am providing in my autoexec.bat a menu
| |
| 04:49 | <alkisg> loadlin might suit you better than grub/bootlace
| |
| 04:49 | <Guest10205> it is like :program1 ....... :eb.net.com
| |
| 04:49 | <alkisg> This way you get to keep your existing menus & structure
| |
| 04:50 | So instead you'd do: program1 .... loadlin gpxe.lkrn
| |
| 04:50 | <Guest10205> and the 2md loads etherboot
| |
| 04:52 | <alkisg> http://youpibouh.thefreecat.org/loadlin/loadlin-1.6e.exe
| |
| 04:52 | <Guest10205> etherboot wich is now gpxe :)
| |
| 04:57 | oh, I see what you mean
| |
| 04:58 | I do not have to use https://help.ubuntu.com/community/UbuntuLTSP/grubgpxe
| |
| 04:58 | alkisg has quit IRC | |
| 04:58 | <Guest10205> instead use loadlin to load gpxe

| |
| 07:28 | they worked for months
| |
| 07:29 | one update too many

| 07:29 | <ddunn> except for one thin client for some reason this one still works
| |
| 07:32 | <robehend1> anyone had luck with firefox as a localapp on 256 megs of ram?
| |
| 07:38 | <muppis> robehend1, I think I have.
| |
| 07:38 | <robehend1> hmm, cool. I just had someone email out of the blue about using some old pent ds with 256 megs of ram as thin clients, and while I was 99% sure it'd run decently, figued i'd check
| |
| 07:39 | also, i love Craigslist. a gentleman just sold me 4 Dell Precision 390 workstations, core 2 quad, 8 gig of ram, for 100 bucks each :D
| |
| 07:39 | <muppis> I check with my vm-client

| |
| 07:40 | <robehend1> we can sure try!
| |
| 07:41 | <csaba> I am trying to boot ltsp via
| |
| 07:43 | using loadlin
| |
| 07:43 | and an image from rom o matic
| |
| 07:44 | robehend1 has left #ltsp | |
| 07:44 | <csaba> it loads until tp=192.168.0.23 ........
| |
| 07:45 | sorry IP=192.168.0.23.....
| |
| 07:46 | any ideas why it would hang there?
| |
| 07:46 | i am loading this from a hdd
| |
| 07:47 | <Barcelo> sorry friends!.
| |
| 07:47 | I have one last question.
| |
| 07:47 | Others who work in the pc clients, are created on the server system.
| |
| 07:47 | # adduser user
| |
| 07:47 | or created in the root of the client system.
| |
| 07:47 | # chroot / opt/ltsp/i386
| |
| 07:47 | # # adduser user

| 09:25 | <robehend1> if i'm running fat clients, the server technically doesnt have to have the ram to support all the clients, correct?
| |
| 09:25 | i.e. boot fat clients off a machine with 512 megs of ram, since the clients use their own ram/cpu

| 10:56 | <muppis> alkisg, I noticed when using dhcp-mac in dnsmasq then name is not provided for that client. This can be a bug in dd-wrt, haven't test that yet.

| 11:00 | <xavierb> I'm testing kde4 with ltsp, looking for the best style and window decoration (to decrease network traffic)
| |
| 11:00 | I've currently selected Phase style and Plastik window decoration
| |
| 11:03 | Anyone has idea about better styles to test ?
| |
| 11:03 | I'm looking also for desktop theme
| |
| 11:06 | Users are womens, so I need something beautiful but not too shiny :)
| |
| 11:06 | <muppis> HMm.. You're asking quite difficult things. ;)
| |
| 11:07 | <xavierb> because of kde4 or because of womens?
| |
| 11:07 | <muppis> Women.
| |

| 12:48 | <robehend1> so, fat clients are my new fave thing
| |
| 12:49 | was able to setup 40 fat clients booting off one virtual server with 8 gigs of ram, and the server barely missed a beat
| |
| 12:51 | <Gadi> robehend1: u could prolly use a lot less ram for that
| |
| 12:51 | :)
| |
| 12:56 | <robehend1> Gadi: yep, i'm adapting it this weekend, down to 2, and then pumping up the other servers on the box with more
| |
| 12:56 | <Gadi> this is why LTSP is so rich! So many choices...
| |
| 12:56 | :)
| |
| 12:57 | <robehend1> mhmm
| |
| 12:57 | I now have my entire 1-4th on LTSp
| |
| 12:57 | kids love it
| |
| 12:57 | teachers love it
| |
| 12:57 | <Gadi> how many machines in total?
| |
| 12:57 | <robehend1> in the elementary? 74
| |
| 12:58 | highschool is running 48 at least count, but number is constantly increasing
| |
| 12:58 | <Gadi> very nice
| |
| 12:58 | you giving them MS apps?
| |
| 12:58 | <robehend1> nope
| |
| 12:58 | well, in one lab. our business lab still is on xp, so that they can teach MS office.
| |
| 12:59 | <Gadi> yeah, I find the MS interfacing to be the biggest struggle
| |
| 13:00 | <robehend1> i hate that ribbon with a passion
| |
| 13:00 | <Gadi> are you doing any clustering or just one VM with LTSP for all?
| |
| 13:00 | <robehend1> one vm. I'm been meaning to try clustering, and now that I just had a nice gentleman agree to sell me a decently powerful workstation, i'm going to try to cluster this weekend
| |
| 13:00 | virtual machine clusters, but enough to get my feet wet
| |
| 13:01 | <Gadi> a much better approach
| |
| 13:01 | I mean stepping it
| |
| 13:01 | clustering can introduce more problems than solutions
| |
| 13:01 | <robehend1> haven't come across any IO issues yet, but that could be because they are using samba shares to store the majority of their files, and we're running mostly fat-clients. biggest bottleneck was the network, but an upgrade to it and the ldm_directx = true cleared that right up
| |
| 13:02 | * Gadi has been finding that out the hard way | |
| 13:02 | <robehend1> ewww said
| |
| 13:03 | i think i may have overprovisioned my highschool server as well. its dual quad core xeons and 32 gigs of ram.
| |
| 13:07 | alkisg has joined #ltsp | |
| 13:09 | <robehend1> alkisg: say, dgroos provided me with a link to your sch-scripts. I take it has to run on the server to be fully effective?
| |
| 13:09 | <alkisg> robehend1: as opposed to where? on ltsp, everything runs on the server...
| |
| 13:10 | <robehend1> alkisg: well, my workstation is a fat client, was wondering if I could run it there, and have it affect the other clients. Namely, the screen broadcasting and such
| |
| 13:11 | <alkisg> Ah. If you can make the daemon run only on your workstation, and the sch-client to run in the other clients, and have an entry in /etc/hosts of other clients with the name "server" pointing to that workstation, sure, you could do that
| |
| 13:11 | <robehend1> that makes sense
| |
| 13:11 | <alkisg> But wouldn't it be simpler to let the daemon run on the server and just run the gui part?
| |
| 13:11 | <robehend1> now that you mention it, yes ;)
| |
| 13:11 | <alkisg> (from the workstation)
| |
| 13:12 | <robehend1> alkisg: i did try running it through ssh x forwarding, and while lockdown and such worked, I wasn't able to view a students screen or display mine on theirs.
| |
| 13:12 | (from a standalone 10.04 laptop, not a fat-client)
| |
| 13:15 | xavierb has quit IRC | |
| 13:16 | <alkisg> Makes sense, with `ssh -X server` and "broadcast screen" you'd be displaying your server screen, not the standalone ws screen...
| |
| 13:17 | <robehend1> ah, ok. thats what i figured. otherwise, fantastic program
| |
| 13:18 | if i can help with translating or anything, let me know
| |
| 13:18 | not that i'd be any good, since I cant read greek...but the willingness must count!
| |
| 13:19 | <m4xx> i've added alt2 to my chroot's /etc/initramfs-tools/modules, will ltsp-update-kernel rebuild the initramfs or do i need to do this manually?
| |
| 13:21 | <alkisg> robehend1: For Ubuntu 12.04 we'll try to have an i18n version and later on we'll try to push it to debian
| |
| 13:21 | <robehend1> i18n? not familiar
| |
| 13:21 | <alkisg> "internationalization"
| |
| 13:21 | <robehend1> ah
| |
| 13:21 | <alkisg> i -18 letters- n
| |
| 13:21 | <robehend1> makes sense for me
| |
| 13:21 | <alkisg> Silly abbreviation, but that's what they use :D
| |
| 13:21 | m4xx: https://help.ubuntu.com/community/UbuntuLTSP/AddingModules
| |
| 13:21 | <robehend1> hey, it makes sense at least
| |
| 13:23 | <muppis> Sounds like my kids has falled asleep, so it might be time to beat the bit a bit.
| |
| 13:23 | <robehend1> i'm hoping that that is a naughty metaphore, but i cant wrap my head around it
| |
| 13:25 | <m4xx> alkisg: awesome thanks!
| |
| 13:28 | i'm getting "No interfaces found! Aborting..." with my eeepc netbook
| |
| 13:28 | any ideas?
| |
| 13:30 | <robehend1> at boot?
| |
| 13:30 | <m4xx> i get splash
| |
| 13:31 | i hit escape, and i see that
| |
| 13:31 | <alkisg> Sounds like there's still a missing module
| |
| 13:31 | Try the steps of that wiki page from the beginning, lspci -nn -k | grep -A 2 Ethernet etc....
| |
| 13:36 | mgariepy has joined #ltsp | |
| 13:38 | <muppis> robehend1, depends what's your metaphore... I still got XP to install..
| |
| 13:40 | And getting odd problem. Having two different nfs export from server, but client mounts always same no matter which one I try.
| |
| 13:42 | toscalix has quit IRC | |
| 13:43 | <m4xx> It has the atheros chipset when thought i enabled by adding alt2 to the modules file.
| |
| 13:43 | <robehend1> muppis: could be worse, could be ME
| |
| 13:43 | alkisg has quit IRC | |
| 13:44 | <muppis> robehend1, sorry, can't help. ;)
| |
| 13:45 | <robehend1> muppis: no no, Windows ME.
| |
| 13:45 | and now, by saying its name, I feel dirty
| |
| 13:45 | <m4xx> microssoft sam?
| |
| 13:45 | anyone?
| |
| 13:45 | ;x
| |
| 13:45 | <robehend1> I still have a disc of MS Bob around
| |
| 13:45 | <m4xx> that's it
| |
| 13:45 | bob
| |
| 13:45 | not sam
| |
| 13:45 | lol
| |
| 13:46 | everything on google says i should only need to add alt2
| |
| 13:49 | <muppis> robehend1, *grin*
| |
| 13:54 | alkisg has joined #ltsp | |
| 13:59 | <m4xx> w00t
| |
| 13:59 | needed alt1c
| |
| 14:00 | <robehend1> sneaky
| |
| 14:00 | those atheros chipsets can be fun it seems
| |
| 14:01 | <m4xx> where in the chroot does it define what port to use in the inetd.conf ?
| |
| 14:01 | alkisg has quit IRC | |
| 14:01 | <robehend1> m4xx: its in pxelinux.cfg/default
| |
| 14:01 | <m4xx> yes
| |
| 14:01 | but when i rebuild image
| |
| 14:01 | it goes back to the wrong port
| |
| 14:01 | i had made a backup of my chroot
| |
| 14:01 | then made a new image
| |
| 14:02 | <muppis> m4xx, build it with -i, so it doesn't 'fix' your pxe.
| |
| 14:02 | <m4xx> now when i update-image it set's it to 2001 instead of 2000
