| 06:35 | <asymptote> How do you create accounts for ltsp clients to login - or are they just regular user accounts you create on the LTSP server with System->Administration->Users&Groups?

| 07:56 | <Appiah> asymptote: do you only use one server?
| |
| 07:56 | then yes its regular users on the server
| |
| 07:56 | <asymptote> Appiah: yeah
| |
| 07:56 | oh ok
| |
| 07:56 | <Appiah> if you use multiple servers consider using ldap
| |
| 07:57 | <asymptote> well I'd probably just put ldap on the ltsp server if I wanted to do that
| |
| 07:57 | I would like to get into using ldap at some point but for now I just want to try getting this ltsp to work
| |
| 07:58 | i'm going to try it now
| |
| 08:01 | Appiah: yeah I can't seem to get past the "verifying password" screen
| |
| 08:02 | <Appiah> do you get a error?
| |
| 08:02 | "no response from server" or similar
| |
| 08:02 | <asymptote> yeah
| |
| 08:02 | I haven't googled that error
| |
| 08:02 | it's prolly common I assume
| |
| 08:02 | <Appiah> well it can mean
| |
| 08:02 | <asymptote> I dunno if I even built the client image - I thought it did that automatically
| |
| 08:02 | <Appiah> * wrong user/password
| |
| 08:03 | * run ltsp-update-sshkeys and ltsp-update-image
| |
| 08:03 | <asymptote> yeah I'm pretty sure I have the right user//pw depending on if I created the user account correctly
| |
| 08:03 | update-image seems to be doing something
| |
| 08:03 | btw I really appreciate you replying
| |
| 08:05 | bah, no response again
| |
| 08:06 | looks like it worked this time
| |
| 08:06 | after I ran update-image, I tried logging in again and it didn't work, so the client rebooted
| |
| 08:06 | and it said "newer version of the image available - rebooting in 10 secs"
| |
| 08:06 | and then I tried logging in again on the client and it worked this time
| |
| 08:07 | so Appiah thanks a lot
| |
| 08:07 | dual nic works - got a network connection on the client
| |
| 08:09 | Appiah: let me ask your opinion - don't you think on this wiki http://is.gd/c1g0A it should say "create a user account and then run ltsp-update-image ?
| |
| 08:09 | <Appiah> Nono
| |
| 08:10 | it has nothing to do with creating users
| |
| 08:10 | <asymptote> mmmm
| |
| 08:10 | well I don't see how ltsp will work if you don't create a user account for the client
| |
| 08:10 | <Appiah> but ltsp-update-sshkeys and ltsp-update-image can fix "no response from server" when something recently changed and you forgot to run ltsp-update-image
| |
| 08:10 | like switching ip or updating kernel
| |
| 08:11 | was just a possible solution
| |
| 08:11 | <asymptote> I disagree with you and I'm editing the wiki anyway
| |
| 08:11 | what good is ltsp if a client can't login
| |
| 08:11 | <Appiah> I think you are mistaking me now
| |
| 08:12 | if you read the mailinglist and check for people who had the problem "no response from server" it usally fixes with ltsp-update-image
| |
| 08:12 | <asymptote> ok sorry if I was
| |
| 08:12 | <Appiah> hence I suuggested you do that
| |
| 08:13 | but check /var/log/messages
| |
| 08:13 | it should give you a hint on why the client couldnt log in
| |
| 08:13 | <asymptote> but if you don't create a user account
| |
| 08:13 | or any account for that matter
| |
| 08:13 | how can the ltsp client login ?
| |
| 08:13 | <Appiah> the server should have one user already?
| |
| 08:13 | all ubuntu installs make you create a user right?
| |
| 08:14 | anwyas asymptote check /var/log/messages , it should tell you exactly the error "no response from server" is a pretty general error in LDM
| |
| 08:14 | can be a problem in lts.conf too
| |
| 08:15 | <asymptote> yes the server should have 1 user
| |
| 08:15 | definitely
| |
| 08:15 | I just think that would be a little clearer
| |
| 08:15 | I dunno - I'm a newb so that's prolly why
| |
| 08:15 | as for the error message yes you can find that but it seems you should run that command regardless
| |
| 08:16 | <Appiah> I dont know what the quick installer does and not so sorry cant comment on the wiki
| |
| 08:16 | <asymptote> as a final step to any installation
| |
| 08:16 | k np
| |
| 08:16 | <Appiah> like I just wrote, I dont know what the alternate does and does not
| |
| 08:16 | jammcq has joined #ltsp | |
| 08:17 | <jammcq> hey kids
| |
| 08:17 | <Appiah> I do my LTSP installs by hand
| |
| 08:17 | jammcq is a expert he might know :)
| |
| 08:17 | <jammcq> heh
| |
| 08:17 | <Appiah> but just check /var/log/messages asymptote it will be much easier
| |
| 08:17 | <jammcq> been a long time since I knew anything helpful in ltsp
| |
| 08:17 | <Appiah> aaw cmon jammcq :)
| |
| 08:18 | and I got to go now \o
| |
| 08:18 | <asymptote> yes I see the error message I just think the error can be avoided if on the wiki it states you run ltsp-update-image
| |
| 08:18 | <Appiah> asymptote: did it help?
| |
| 08:18 | alkisg has joined #ltsp | |
| 08:19 | <asymptote> yes it did
| |
| 08:19 | <Appiah> oh
| |
| 08:19 | <asymptote> running that command did
| |
| 08:19 | <Appiah> did you change IP after installing the LTSP?
| |
| 08:19 | <asymptote> yeah but I ran update-ssh-keys or whatever per the wiki's instructions
| |
| 08:19 | <Appiah> ah
| |
| 08:19 | <asymptote> also I did an amd64 installation and you have to modify anything that says i386
| |
| 08:20 | <Appiah> then I see why you want to edit the wiki
| |
| 08:20 | its old
| |
| 08:20 | <asymptote> to amd64
| |
| 08:20 | well
| |
| 08:20 | fall of 09
| |
| 08:20 | yeah I'll edit it
| |
| 08:20 | <Appiah> Are you installing on Hardy btw?
| |
| 08:20 | <asymptote> oh hell no
| |
| 08:20 | 10.04 man
| |
| 08:20 | <Appiah> well then thats why
| |
| 08:20 | I think the ltsp-update-sshkeys changed since then
| |
| 08:20 | so the wiki might not be wrong
| |
| 08:20 | Eghie has joined #ltsp | |
| 08:20 | <Appiah> just not updated for 10.04
| |
| 08:21 | <asymptote> that command works
| |
| 08:21 | <Appiah> now I really gotta run
| |
| 08:21 | <asymptote> I ran it before
| |
| 08:21 | k well ty for the help
| |
| 08:21 | <Appiah> yes but what the script DOES maybe changed!
| |
| 08:21 | :D
| |
| 08:22 | maybe request it to be updated for 10.04 instead of changing it for people who still want to run hardy for some reason >_>
| |
| 08:22 | <asymptote> I can just put in a 10.04 section
| |
| 08:22 | <alkisg> That would be best. Which page is that?
| |
| 08:22 | <asymptote> http://is.gd/c1g0A
| |
| 08:23 | <alkisg> ...and what is it that changed in 10.04?
| |
| 08:24 | <asymptote> I don't know of anything that did - but Appiah was suggesting that perhaps the update-sshkeys script may have changed
| |
| 08:24 | <alkisg> It did change, but not its general functionality
| |
| 08:24 | <Appiah> *sigh*
| |
| 08:24 | <asymptote> all I wanted to do was add some entries like stating that you have to run ltsp-update-image
| |
| 08:24 | <alkisg> I don't see anything in that wiki page that needs to be changed... am I missing something?
| |
| 08:24 | <Appiah> he couldnt log on , and i suggested he ran ltsp-update-image and it worked
| |
| 08:25 | <asymptote> well I had to create an account too
| |
| 08:25 | alkisg: you cannot log into a client with the directions that are present on that install guide
| |
| 08:25 | <Appiah> and I'm just saying maybe alternate installer is different from 8.04
| |
| 08:25 | _maybe_
| |
| 08:25 | <asymptote> look i'm going to edit it and if someone else wants to remove it that's their business but I think it's incomplete
| |
| 08:25 | and misleading
| |
| 08:25 | <Appiah> and the wiki needs to be updated for 10.04
| |
| 08:26 | <alkisg> asymptote: you should. I you couldn't, and you needed to run ltsp-update-image without your IP being changed, then that's a bug
| |
| 08:26 | Not an error on the wiki
| |
| 08:26 | <Appiah> clear!
| |
| 08:26 | * Appiah waves | |
| 08:30 | <asymptote> well editing the wiki will take much less time than a bug being fixed
| |
| 08:30 | so in the meantime
| |
| 08:30 | the wiki will be changed
| |
| 08:31 | oh actually
| |
| 08:31 | it says to run update-image
| |
| 08:31 | already
| |
| 08:31 | hmm...I didn't see that before
| |
| 08:32 | <alkisg> asymptote: please don't change the wiki if it is a bug
| |
| 08:33 | Either file a bug (the best option) or wait for someone else to file it.
| |
| 08:33 | You could make a referense to the bug number in the wiki,
| |
| 08:33 | <asymptote> why
| |
| 08:33 | I'm not going to because it says in the wiki to run those commands
| |
| 08:33 | but suppose it didn't
| |
| 08:33 | <alkisg> but it wouldn't be OK to change the instructions so that the people assume that that's the correct way to do things, when it isn't
| |
| 08:34 | Generally, you don't need to run ltsp-update-image after installing from the alternate cd
| |
| 08:34 | <asymptote> so I'd just add an entry and say "oh btw a bug report has been filed"
| |
| 08:34 | <alkisg> If one needs to run it, then he either changed his ip, or it's a bug
| |
| 08:36 | <asymptote> well guess what alkisg
| |
| 08:36 | you DO need to run it, it IS a bug, and someone put a wiki entry stating that
| |
| 08:37 | so either way you lose
| |
| 08:37 | <alkisg> What do I lose?
| |
| 08:37 | <asymptote> unless you want to just waltz in there and remove the entry
| |
| 08:37 | <alkisg> If it's a bug, just file it on launchpad so that we can fix it
| |
| 08:38 | I do know that ltsp-update-sshkeys was a little broken
| |
| 08:38 | <asymptote> it's been filed, as I've already stated
| |
| 08:38 | <alkisg> OK, what's the bug # ?
| |
| 08:38 | <asymptote> 144296
| |
| 08:38 | <alkisg> OK, just mention that bug # in the wiki.
| |
| 08:38 | <asymptote> it says it at the bottom of the wiki
| |
| 08:38 | IT'S ON THERE
| |
| 08:38 | <alkisg> ok
| |
| 08:38 | <asymptote> AR EYOU BLIND
| |
| 08:39 | I TOLD YOU THREE TIMES NOW
| |
| 08:39 | <alkisg> asymptote: are you ok man?
| |
| 08:39 | <jammcq> whoa
| |
| 08:39 | <asymptote> nah ttyl
| |
| 08:39 | asymptote has left #ltsp | |
| 08:39 | <jammcq> someone needs to settle down
| |
| 08:39 | I guess someone woke up grumpy this morning
| |
| 08:40 | <alkisg> Did I say anything wrong without realizing it?
| |
| 08:40 | <jammcq> nothing that I could tell
| |
| 08:40 | <alkisg> Ty... :-/
| |
| 08:41 | BTW, #144296 is a gutsy bug... not valid on lucid...

| 09:23 | <bcgrown> hi, anyone know how I can connect to an LTSP server from within xubuntu?
| |
| 09:24 | i've installed ldm but i'm not sure how to use that instead of gdm

| |
| 10:45 | F-GT has joined #ltsp | |
| 11:04 | bcgrown has joined #ltsp | |
| 11:05 | <alkisg> bcgrown: are you trying to install ldm on a standalone machine and connect to an ltsp server with it?
| |
| 11:05 | <bcgrown> alkisg, yeah. i have an xubuntu laptop that i want to use as a client. i also want to retain the normal xubuntu functionality, though
| |
| 11:06 | <alkisg> bcgrown: we usually don't use ltsp in that case, but e.g. neatx or something similar
| |
| 11:06 | (vnc, xdmcp, ssh -X etc)
| |
| 11:07 | <bcgrown> alkisg: I don't want to do that because I use the server as a htpc
| |
| 11:07 | alkisg: I haven't found a good way to run a whole gnome-session over ssh _X
| |
| 11:07 | <alkisg> bcgrown: and? neatx runs a gnome-session over ssh...
| |
| 11:07 | <bcgrown> hm
| |
| 11:07 | i didn't know that
| |
| 11:07 | <alkisg> (==freenx, nx server etc)
| |
| 11:08 | bcgrown: what distro/version is the ltsp server?
| |
| 11:08 | <bcgrown> alkisg: 5.2.1 running on mythbuntu. it sounds like nx might be easier though?
| |
| 11:09 | <alkisg> bcgrown: I meant the distro version... is that e.g. like karmic or like lucid?
| |
| 11:09 | <bcgrown> lucid
| |
| 11:09 | <alkisg> OK, then neatx is your best option
| |
| 11:09 | sudo add-apt-repository ppa:freenx-team
| |
| 11:09 | sudo apt-get update
| |
| 11:09 | sudo apt-get install neatx-server
| |
| 11:10 | That's all on the ltsp-server side
| |
| 11:10 | On the client, you just download the nx client from the nomachine site
| |
| 11:10 | (google it it comes first on the results)
| |
| 11:10 | <bcgrown> but I will have to install ubuntu-desktop on the server, right? the last time i tried that it didn't play too nicely with the existing xfce desktop
| |
| 11:10 | <alkisg> No reboots/logoffs etc necessary, it just works...
| |
| 11:11 | Hmmm I'm not sure about that. Shouldn't neatx work with other desktops? I really don't know...
| |
| 11:11 | Did you try neatx or freenx?
| |
| 11:11 | <bcgrown> yeah but i want to keep the xfce desktop on the server and run a gnome desktop on the client
| |
| 11:11 | <alkisg> Er, wait, how are you planning to do that?
| |
| 11:12 | Install both desktops on the server?
| |
| 11:12 | <bcgrown> yes
| |
| 11:12 | <alkisg> Sure, the client has an option for the desktop in that case
| |
| 11:12 | You just select "gnome" from the nx client
| |
| 11:13 | <bcgrown> alkisg: the problem is that gnome installs some things that conflict with xfce, like the volume daemon for instance. speaking of which... i also want to be able to send audio to the client, and use the client's usb devices
| |
| 11:13 | which is why I thought LTSP was the thing to use
| |
| 11:14 | the whole reason for doing this by the way, is that my server is fast and my laptop (client) is old and slow
| |
| 11:14 | <alkisg> ltsp doesn't play nice if you don't boot with it
| |
| 11:14 | It'd be nice to have ldm work like you say, and it may be implemented in the future.
| |
| 11:14 | But currently, just installing ldm to a standalone pc doesn't work as expected...
| |
| 11:15 | Why don't you want to boot with ltsp?
| |
| 11:15 | <bcgrown> an X-forwarded gnome session still uses the server's USB i believe\
| |
| 11:15 | <alkisg> Yes. And it also uses the sound card of the server...
| |
| 11:15 | komunista has joined #ltsp | |
| 11:15 | <bcgrown> well i've read that can be forwarded with pulseaudio
| |
| 11:15 | <alkisg> Sure, that's what ltsp does
| |
| 11:15 | <bcgrown> alkisg: boot ltsp on the client? i have no problem with that
| |
| 11:16 | <alkisg> bcgrown: that's what ltsp is for
| |
| 11:16 | To boot the client with it, so that everything (sound etc) plays out of the box..
| |
| 11:16 | <bcgrown> yeah that's not a problem, i can dual-boot with xubuntu
| |
| 11:17 | <alkisg> Do that then, it'll be much more straightforward
| |
| 11:17 | <bcgrown> i thought edubuntu could do it but when i tried the livecd it only had an option to test an ltsp server
| |
| 11:17 | is there a better distro to use?
| |
| 11:17 | (for the client)
| |
| 11:17 | <alkisg> test an ltsp server ==> isn't that what you want?
| |
| 11:17 | (test, and then, install it...)
| |
| 11:18 | You don't need an OS on the client
| |
| 11:18 | It boots from the network
| |
| 11:18 | <bcgrown> hm
| |
| 11:18 | no wonder i couldn't find it then!
| |
| 11:18 | <alkisg> You don't install anything on the client, it doesn't even need to have a disk
| |
| 11:18 | <bcgrown> lol
| |
| 11:18 | can that be done over wifi
| |
| 11:18 | <alkisg> Nope
| |
| 11:18 | (not easily)
| |
| 11:18 | <bcgrown> what's the difficult way?
| |
| 11:19 | it's no use to me if i have to be wired
| |
| 11:19 | <alkisg> In your case, you could put the ltsp kernel in your local disk, include the wifi driver in it, and modify the initramfs to setup the connection, and then chainload to the ltsp server
| |
| 11:19 | <bcgrown> ugh
| |
| 11:19 | <alkisg> I'm not sure if it's worth it
| |
| 11:20 | <bcgrown> isn't there any software that can retrieve the relevant boot info over the network? that i could use with a minimal linux or something
| |
| 11:21 | <alkisg> Generally, wireless booting isn't easy
| |
| 11:21 | <bcgrown> durn
| |
| 11:22 | <miklove> How do I re-create nbi.img without doing a ltsp-build-image?
| |
| 11:37 | <bcgrown> alkisg: trying to boot pxe wired now... but I'm a little confused about DHCP. won't my router try to give the client an IP address?
| |
| 11:37 | <alkisg> bcgrown: typically an ltsp server has 2 nics. The second one is on a different switch, so it gives IP addresses to the thin clients connected there.
| |
| 11:38 | If you got everything on the same switch as the router, and you don't want to disable dhcp on it, a suitable solution is this: https://help.ubuntu.com/community/UbuntuLTSP/ProxyDHCP
| |
| 11:38 | <bcgrown> ugh, that looks complicated
| |
| 11:56 | hmm, doesn't seem to work on my old machine anyway :(
