| 08:52 | <sbalneav> Morning all
| |
| 08:54 | <Appiah> hello
| |
| 08:55 | <CAN-o-SPAM> hey sbalneav
| |
| 08:56 | Brian_H has joined #ltsp | |
| 08:58 | rjune has quit IRC | |
| 08:59 | <Appiah> is italc still under development?
| |
| 08:59 | rjune has joined #ltsp | |
| 09:01 | bieb has joined #ltsp | |
| 09:05 | <sbalneav> Appiah: Far as I know.
| |
| 09:06 | I think stgraber's maintaining the package.
| |
| 09:06 | <Appiah> ah oki
| |
| 09:08 | <sbalneav> CAN-o-SPAM: Morning
| |
| 09:08 | <alkisg> Appiah: it's "on hold" - we're waiting for the developer to release italc 2.0
| |
| 09:08 | <CAN-o-SPAM> any of the white stuff up there yet sbalneav?
| |
| 09:09 | <alkisg> Appiah: he said that would happen somewhere in 2010...
| |
| 09:09 | * alkisg wishes that italc supported multicasting in demo mode... :( | |
| 09:10 | <Appiah> arggh
| |
| 09:11 | somewhere 2010..
| |
| 09:11 | dec ? :)
| |
| 09:11 | <dro> alkisg: I'm getting ready to do my testing with proxydhcp and 9.10
| |
| 09:11 | <Appiah> How about sabayon then?
| |
| 09:12 | <alkisg> Appiah: I'd wish... I hope that he doesn't completely abandon the project. Or, if he does, that he posts whatever code he has ready for italc 2.0, so someone else can pick it up... unfortunately he don't have any other good open source alternatives to italc :(
| |
| 09:12 | <Appiah> two things I miss from my LTSP setup
| |
| 09:12 | ideal setup*
| |
| 09:12 | <alkisg> dro: nice, if you need any help ping me
| |
| 09:12 | <Appiah> alkisg: hope so too
| |
| 09:13 | <alkisg> Appiah: are you using it? and if so, in what network? (gigabit)?
| |
| 09:13 | <Appiah> iTalc? no , didnt work last time i tried
| |
| 09:13 | over 6 months ago..
| |
| 09:13 | <alkisg> Heh...
| |
| 09:13 | <Appiah> gonna give it another try in a labb soon
| |
| 09:13 | <alkisg> No it's really easy to set it up
| |
| 09:14 | Brian_H has quit IRC | |
| 09:14 | <Appiah> sometimes I couldnt connect to the clients
| |
| 09:14 | <alkisg> In LTSP, you *only* need to do "apt-get install ltsp-master" - nothing else
| |
| 09:14 | <Appiah> impossible to group the clients etc
| |
| 09:14 | Brian_H has joined #ltsp | |
| 09:14 | <dro> alkisg: my only concern is having 2 proxydhcp ltsp servers, they won't fight with each other will they?
| |
| 09:14 | <alkisg> 2??!!! Why?
| |
| 09:14 | <dro> alkisg: the current stable one, and the beta testing one
| |
| 09:14 | <alkisg> (2 ltsp servers, ok, but 2 *proxy* ones?)
| |
| 09:15 | dro, how will the client know which one to select?
| |
| 09:15 | <dro> alkisg: is there is a way I can push the proxy 9.04 one to use the 9.10 new one
| |
| 09:15 | squarepeg has joined #ltsp | |
| 09:15 | <dro> alkisg: as soon as I get the 9.10 tested and working, the old one will be shut off
| |
| 09:16 | ogra_ has joined #ltsp | |
| 09:16 | <alkisg> Well you can tell them to answer or not to answer at specific mac addresses...
| |
| 09:16 | ...but I don't know the exact dnsmasq.conf syntax for that - I bet you can find examples, though...
| |
| 09:17 | <dro> alkisg: no worries, they're both virtualized, I'll just use the internal nic
| |
| 09:17 | alkisg: on my test box and the test ltsp server
| |
| 09:17 | <alkisg> You'll need a real internal dhcp server then...
| |
| 09:17 | ogra has quit IRC | |
| 09:17 | <sbalneav> CAN-o-SPAM: We had some this weekend when I shut down the cottage.
| |
| 09:17 | <alkisg> dro: ...or you'll need to change ltsp.conf to tell dnsmasq to provide real leases
| |
| 09:18 | <dro> alkisg: i'll just run them side by side then, and shut off the old one's nic while I do my testing
| |
| 09:18 | <sbalneav> Appiah: sabayon is working in Karmic, or at least it should be. If it doesn't contact me. I'm maintaining the package.
| |
| 09:18 | <Appiah> hmm
| |
| 09:18 | how about Jaunty then? :)
| |
| 09:18 | <alkisg> dro: just do: `sudo invoke-rc.d dnsmasq stop` on the old one for a while.
| |
| 09:18 | <sbalneav> Appiah: You can install a jaunty sabayon package from my ppa
| |
| 09:18 | <dro> alkisg: ok, cool ty
| |
| 09:19 | <Appiah> I tried one last week on a ltsp amd64 server
| |
| 09:19 | crashed when I clicked edit
| |
| 09:19 | <Brian_H> with samba handling permissions is pretty easy, how do you do manage them with nfs? Is there a way to prevent one ltsp user from modifying anothers home directory?
| |
| 09:19 | <sbalneav> Appiah: Did you install the one from my ppa?
| |
| 09:19 | <Appiah> yupp
| |
| 09:20 | <sbalneav> Did you file a bug?
| |
| 09:20 | <Appiah> not yet
| |
| 09:20 | <sbalneav> when you do:
| |
| 09:20 | <Appiah> can do tonight
| |
| 09:20 | <sbalneav> or, if you'd like to debug it right now...
| |
| 09:21 | <Appiah> hmmm
| |
| 09:21 | gimme a few mins
| |
| 09:24 | oki
| |
| 09:25 | ogra_ has quit IRC | |
| 09:25 | ogra has joined #ltsp | |
| 09:26 | <sbalneav> ogra: I'm going to package up that thing you pointed me to this week.
| |
| 09:26 | <Appiah> sbalneav: http://pastebin.ca/1653178
| |
| 09:26 | <sbalneav> So we can start playing with it.
| |
| 09:26 | <ogra> sbalneav, its unmaintained since 2 years (or longer) and its not complete
| |
| 09:27 | it should serve as a base for what we plan though
| |
| 09:27 | <sbalneav> right
| |
| 09:27 | we may have to maintain it :)
| |
| 09:28 | <ogra> i'm also not sure about how sane it is ... we should talk to Keybuk about it
| |
| 09:28 | <sbalneav> Appiah: yeah, that's useless debug information.
| |
| 09:28 | <ogra> i guess he will rather propose something thats similar but directly integrated into dbus
| |
| 09:28 | <Appiah> oki so what do you need
| |
| 09:28 | <sbalneav> hold on, I'll give you the magic you need to get something useful
| |
| 09:29 | <Appiah> I got some strace too?
| |
| 09:29 | <sbalneav> did you?
| |
| 09:29 | Egyptian[Home] has quit IRC | |
| 09:30 | <sbalneav> Appiah: OK, you need to create, in root's home dir, a file called sabayon-debug-log.conf
| |
| 09:30 | with the following information:
| |
| 09:31 | <ltsppbot> "sbalneav" pasted "sabayon-debug-log.conf" (3 lines) at http://pastebot.ltsp.org/1
| |
| 09:31 | <sbalneav> Then re-run sabayon.
| |
| 09:34 | <Appiah> looks about the same now
| |
| 09:34 | I think I did something wrong
| |
| 09:34 | artista_frustrad has quit IRC | |
| 09:37 | <Appiah> sbalneav: the log looks exactly the same
| |
| 09:37 | artista_frustrad has joined #ltsp | |
| 09:37 | <Appiah> after adding that file
| |
| 09:40 | <sbalneav> so you created /root/sabayon-debug-log.conf
| |
| 09:40 | right?
| |
| 09:41 | <Appiah> yupp
| |
| 09:41 | rjune_ has joined #ltsp | |
| 09:41 | <Appiah> i inserted that text that you pasted
| |
| 09:41 | 3 lines
| |
| 09:41 | Ahmuck-Sr has joined #ltsp | |
| 09:42 | <Appiah> oh wait
| |
| 09:42 | adrien has joined #ltsp | |
| 09:42 | <Appiah> i named it .sabayon-debug-log.conf for some reason
| |
| 09:42 | my bad
| |
| 09:43 | got some output now
| |
| 09:43 | <sbalneav> bingo.
| |
| 09:44 | dro has quit IRC | |
| 09:44 | dro_ has joined #ltsp | |
| 09:44 | <Appiah> http://pastebin.ca/1653203
| |
| 09:45 | <ltsppbot> "dro" pasted "Alkisg, you want me to replace" (12 lines) at http://pastebot.ltsp.org/2
| |
| 09:46 | <dro_> alkisg: will you took a look at that pastebin
| |
| 09:48 | <sbalneav> Appiah: So where, exactly, is it crashing?
| |
| 09:48 | <Appiah> when I push edit
| |
| 09:48 | on the profile
| |
| 09:49 | <alkisg> dro, thanks, I have some time now, I'll take care of that wiki page...
| |
| 09:49 | btw, did it work for you?
| |
| 09:50 | <dro_> alkisg: the command I posted in the pastebin didn't work
| |
| 09:50 | <sbalneav> So you highlight the profile, press edit, and get an immediate crash? No window attempts to load?
| |
| 09:50 | <dro_> but I believe I need to create: /opt/ltsp/i386/etc/ltsp/update-kernels.conf first for it to work
| |
| 09:50 | <alkisg> dro_: you also need the mkdir
| |
| 09:50 | <dro_> alkisg: just noticed that, ty
| |
| 09:50 | <alkisg> dro_: wait, let me fix the page, and you follow the instructions there to see if they work
| |
| 09:51 | ok
| |
| 09:51 | <Appiah> sbalneav: pretty much , I get an error box saying that I should send the log to bugzilla
| |
| 09:51 | <sbalneav> ok. Can you do this for me?
| |
| 09:51 | getent passwd sabayon-admin
| |
| 09:51 | <Appiah> to launchpad or to bugzilla?
| |
| 09:51 | <sbalneav> should be one line, you can just paste it here
| |
| 09:51 | <Appiah> oh wait
| |
| 09:52 | sabayon-admin:x:2100:2003:Sabayon user::/sbin/nologin
| |
| 09:53 | <dro_> alkisg: ok I will be testing in about 5 minutes
| |
| 09:53 | <sbalneav> yeah, that's whong for sure.
| |
| 09:53 | ok
| |
| 09:53 | <Appiah> how did this happen? :)
| |
| 09:53 | <sbalneav> so, let's purge the package.
| |
| 09:53 | <Appiah> aw crap
| |
| 09:54 | <sbalneav> you probably installed an older version of the package, that had a packaging bug
| |
| 09:54 | <Appiah> 2000 thats where the ldap users begin >_>
| |
| 09:54 | <sbalneav> right
| |
| 09:54 | <Appiah> k
| |
| 09:54 | let me purge then
| |
| 09:54 | <sbalneav> apt-get purge sabayon
| |
| 09:54 | then we might have to manually do some cleanup
| |
| 09:54 | <Appiah> i did apt-get remove sabayon --purge
| |
| 09:54 | is that the same?
| |
| 09:55 | <sbalneav> maybe
| |
| 09:55 | give it a try
| |
| 09:55 | <Appiah> well its done already
| |
| 09:55 | <sbalneav> ok
| |
| 09:55 | so, getent passwd sabayon-admin should return nothing
| |
| 09:55 | <Appiah> the user is gone
| |
| 09:55 | yupp nothing
| |
| 09:56 | <sbalneav> getent group sabayon-admin should return nothing?
| |
| 09:56 | <Appiah> its empty
| |
| 09:56 | <sbalneav> ok
| |
| 09:56 | and there should be no /var/run/sabayon-admin dir, right?
| |
| 09:57 | <Appiah> no such dir
| |
| 09:57 | <sbalneav> ok
| |
| 09:57 | and you've got my ppa in your sources.list, right?
| |
| 09:57 | grep sbalneav /etc/apt/sources.list
| |
| 09:57 | <Appiah> i put it in a seperate file
| |
| 09:57 | <sbalneav> ok
| |
| 09:57 | that's fine.
| |
| 09:57 | <Appiah> sources.list.d/ppa.list
| |
| 09:57 | <dro_> alkisg: it worked, but it didn't give me the extra boot option like before
| |
| 09:58 | <sbalneav> so install sabayon then, lets see if we get the right user.
| |
| 09:58 | <alkisg> dro_: what extra boot option?
| |
| 09:58 | <Appiah> sabayon_2.27.91-0ubuntu6~ppa6_amd64.deb
| |
| 09:58 | <dro_> alkisg: before it said, press f8 to boot locally
| |
| 09:58 | <Appiah> sabayon-admin:x:116:61:Sabayon user:/var/run/sabayon-admin:/bin/sh
| |
| 09:58 | looks better
| |
| 09:58 | <alkisg> dro_: it should also have that now. Can you put your dnsmasq.d/ltsp.conf to pastebot?
| |
| 09:59 | <Appiah> still crashes =/
| |
| 09:59 | tstafford_ has joined #ltsp | |
| 09:59 | <sbalneav> ok, but lets see the log now.
| |
| 10:00 | <ltsppbot> "dro" pasted "# Sample configuration for dns" (58 lines) at http://pastebot.ltsp.org/3
| |
| 10:00 | <Appiah> http://pastebin.ca/1653222
| |
| 10:02 | <alkisg> dro_: that looks fine, it should show the F8 menu. Are you using the same client as before?
| |

| 10:02 | MainThread 2009/11/02 16:56:47.0620 (proto-session): Clobbering existing processes running as user 'sabayon-admin': ['/usr/bin/pkill', '-u', 'sabayon-admin']

| |
| 10:02 | Hm
| |
| 10:02 | MainThread 2009/11/02 16:56:47.5647 (admin-tool): Got fatal error: sabayon-session exited with a FATAL ERROR (exit code 1)
| |
| 10:02 | <dro_> alkisg: yes, I'm rebooting the ltsp server now
| |
| 10:02 | <sbalneav> Appiah: Do you have any processes running as sabayon-admin?
| |
| 10:02 | <alkisg> dro_: also, the tftp directory is wrong (both on the wiki and your file), I'll correct that now...
| |
| 10:03 | <Appiah> sbalneav: lemme check
| |
| 10:03 | ps ax says I'm not
| |
| 10:03 | <sbalneav> k, try this
| |
| 10:04 | Appiah: how are you running sabayon? from the administration menu?
| |
| 10:04 | <Appiah> terminal
| |
| 10:04 | <sbalneav> How?
| |
| 10:04 | <Appiah> sudo sabayon
| |
| 10:04 | <sbalneav> bad boy
| |
| 10:04 | gksu sabayon
| |
| 10:04 | <Appiah> :)
| |
| 10:05 | <sbalneav> Try it from the admin menu LIKE YOUR SUPPOSED TO
| |
| 10:05 | <Appiah> and it worked
| |
| 10:05 | I feel ashamed
| |
| 10:05 | * sbalneav slaps Appiah with a wet trout. | |
| 10:05 | <sbalneav> \o/ problem solved!
| |
| 10:06 | <Appiah> reason why I'm not trying from menu now is beacuse I'm working remotly (ssh -X)
| |
| 10:06 | <sbalneav> ah, ok
| |
| 10:06 | <Appiah> gaah should have thought of that
| |
| 10:06 | <sbalneav> use gksu, sudo doesn't set up the X environment correctly
| |
| 10:06 | <Appiah> well thanks , Now we can start using your PPA package
| |
| 10:06 | ye I noticed the .xauth in the terminal
| |
| 10:06 | <sbalneav> sudo for command line stuff gksu for X stuff
| |
| 10:07 | <Appiah> well thanks alot!
| |
| 10:07 | <sbalneav> Perfect, well glad we got that sorted.
| |
| 10:07 | <Appiah> or should I say .. for now ? :)
| |
| 10:07 | <sbalneav> Well, any further problems, gimme a ping
| |
| 10:07 | <Appiah> I will
| |
| 10:07 | Now it's time for me to go home
| |
| 10:07 | <alkisg> dro_: the wiki page should be OK now.
| |
| 10:07 | <dro_> alkisg: ok i'll make the change
| |
| 10:08 | alkisg: but once again, the problem I hoped the upgrade would fix is happening again, darn it
| |
| 10:08 | <alkisg> What was that?
| |
| 10:08 | <sbalneav> I should probably add a check to sabayon so that it will refuse to run if then environment's not right.
| |
| 10:08 | * sbalneav makes note | |
| 10:09 | <stgraber> sbalneav: hey, did you send me that WM code ? I didn't receive anything but it could have been eaten by my anti-spam.
| |
| 10:09 | <dro_> these client computers have an internal speaker that plays music/sound, and I want it to be silent/off
| |
| 10:09 | alkisg: I want it to where the clients only get sound if they plug in headphones, or external speakers
| |
| 10:09 | <Ahmuck-Sr> dro_: bios
| |
| 10:09 | <alkisg> dro_: didn't you solve this by setting VOLUME=0 ?
| |
| 10:09 | <sbalneav> stgraber: Argh
| |
| 10:09 | <alkisg> Ah
| |
| 10:09 | <sbalneav> sorry
| |
| 10:09 | I'll do it in 5
| |
| 10:09 | <Ahmuck-Sr> dro, you need to disable it in the bios

| 10:10 | <alkisg> dro_: `man lts.conf` and search for VOLUME, maybe one of those is what you're looking for.
| |
| 10:10 | <Gadi> dro_: another approach is to run ltsp-localapps xterm from a terminal, and then while playing a sound, run alsamixer and play with muting the channels
| |
| 10:10 | <dro_> There are hundreds of these guys all over all my client's installs, and I'm sure they'll get a ton more. I have been pulling the speakers but would love to resolve it at a central point. A desktop install of 9.04 didn't work, but when I installed 9.10 on one of them by default the internal speaker didn't work
| |
| 10:11 | <Gadi> once you find the channel for the internal speakers, you can set only *its* volume to 0 in lts.conf
| |
| 10:11 | <Ahmuck-Sr> dro_: r u tyring to disable sound altogather?
| |
| 10:11 | <dro_> Ahmuck-Sr: no, i just want only the headphone/speaker jack to work
| |
| 10:11 | <Ahmuck-Sr> or just the local speakers in the pc?
| |
| 10:12 | <Gadi> volume parameters in lts.conf are: <channel_name_in_caps>_VOLUME
| |
| 10:12 | <dro_> Gadi: ty I will look into that
| |
| 10:16 | <Gadi> fyi: if the channel name has a space, replace the space with an underscore in the parameter name, iirc
| |
| 10:18 | <dro_> Gadi: is there a list of all channels?
| |
| 10:20 | <alkisg> I got an HP T5000 thin client. Is there any keypress to load the BIOS setup? And/or to boot from a usb stick?
| |
| 10:21 | <sbalneav> F2/F12?
| |
| 10:21 | <alkisg> Hmmm I only tried "Del", trying... :)
| |
| 10:23 | Ah, bless syslinux, I can boot from the usb stick using syslinux...

| 10:35 | <Ahmuck-Sr> ubuntu ltsp has a loooooooong login choice screen. is there a way to restrict the logon window to a username/password?
| |
| 10:35 | <dro_> Gadi: will you explain how to run lts-localapps xterm from a terminal?
| |
| 10:38 | <_UsUrPeR_> dro_: open a terminal on the desktop of the TC that you intend to use xterm on
| |
| 10:38 | dro_: In that terminal, enter the following: "ltsp-localapps xterm"
| |
| 10:38 | dro_: that should be it for you
| |
| 10:39 | <dro_> _UsUrPeR_: ty
| |
| 10:42 | <sbalneav> Ahmuck-Sr: What do you mean, turn off the menu at the bottom?
| |
| 10:42 | <dro_> _UsUrPeR_: ok I have the xterm open now, but I tried to run alsamixer but it failed
| |
| 10:42 | <_UsUrPeR_> dro_: what's the error?
| |
| 10:43 | <dro_> _UsUrPeR_: function snd_ctl_open failed for default: No such file or directory
| |
| 10:43 | <Ahmuck-Sr> sbalneav: all my users are on a long list at the server
| |
| 10:44 | so one has to scroll the list to find the correct user and then click to login
| |
| 10:44 | <sbalneav> On the thin client?
| |
| 10:44 | <Ahmuck-Sr> server
| |
| 10:44 | the thin client is still using 9.04 login screen
| |
| 10:44 | <sbalneav> That's got nothing to do with ltsp
| |
| 10:44 | that's gdm on the server.
| |
| 10:44 | <Ahmuck-Sr> it appears that the 9.04 login screen did not change to 9.10
| |
| 10:45 | <_UsUrPeR_> dro_: running ltsp-localapps with any program (or xterm run via ltsp-localapps) creates an active terminal session which is running directly off the TC. That meants that if the program is not installed in the chroot, it, by all rights and purposes pertaining to the OS, does not exist. Did you install alsamixer in the chroot?
| |
| 10:45 | <sbalneav> the ltsp login screen is it's own thing: LDM
| |
| 10:45 | <Ahmuck-Sr> before gdm only showed one user login, now it shows the entire class
| |
| 10:45 | <sbalneav> Ahmuck-Sr: right.
| |
| 10:45 | <dro_> _UsUrPeR_: nope, i'll do that now
| |
| 10:45 | <sbalneav> that's ubuntu's new login screen.
| |
| 10:45 | <Ahmuck-Sr> ok, i'll try to find the gdm login screen and try to restrict it to one user
| |
| 10:45 | oh, is there a one user option that you know of?
| |
| 10:46 | <sbalneav> No. Not that I know of

| 11:03 | <dro_> _UsUrPeR_: when I choose sound card pref in gnome-alsamixer it crashes lol, i'll try alsamixergui
| |
| 11:04 | <_UsUrPeR_> dro_: You may need to set SOUND = false in /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 11:04 | dro_: what is your intention pertaining to alsamixer? Why are you using that instead of gnome's volume controller?
| |
| 11:04 | <dro_> _UsUrPeR_: already set
| |
| 11:05 | _UsUrPeR_: gadi suggested that I run it, to see what audio channels are running, and turn the one running my internal speaker off
| |
| 11:05 | When I go into the regular audio controls, I can set it to be "headphones" and everything works fine, sound only works with headphones or external speakers
| |
| 11:06 | <_UsUrPeR_> dro_: is your intention to use both at the same time?
| |
| 11:06 | <dro_> _UsUrPeR_: no my intention is to turn the internal speaker off
| |
| 11:07 | <_UsUrPeR_> dro_: aah. Bummer. Are you using a thin client or a PC?
| |
| 11:07 | <dro_> that way only speakers/headphones work
| |
| 11:07 | _UsUrPeR_: this is a reg pc, but it's very small
| |
| 11:09 | <_UsUrPeR_> dro_: this may seem rudimentary in comparison, but is unplugging/removing the internal speaker an option? The reason I ask, is it may not be possible to separate the two audio feeds.
| |
| 11:10 | <dro_> _UsUrPeR_: that is the last option I want to take, we have deployed over 400 of those guys
| |
| 11:10 | <Ahmuck-Sr> sbalneav: no workie
| |
| 11:10 | <dro_> _UsUrPeR_: spread across a couple different customer's sites
| |
| 11:10 | _UsUrPeR_: it's not all this model either, just any model that has an internal speaker
| |
| 11:11 | <Ahmuck-Sr> dro_: again, i'd turn off the internal speaker in the BIOS
| |
| 11:12 | <_UsUrPeR_> Ahmuck-Sr/dro_: that may work as well :)
| |
| 11:12 | <dro_> Ahmuck-Sr: I know that is an option, and I have for a lot of them, but once again there are a ton of these already deployed and I would like to search for a centralized fix
| |
| 11:13 | I thought for sure the audio config file would be in 1 central point and I could make the changes there
| |
| 11:14 | <johnny> "When I go into the regular audio controls, I can set it to be "headphones" and everything works fine, sound only works with headphones or external speakers"
| |
| 11:14 | ok.. so what's the problem with that
| |
| 11:14 | ?
| |
| 11:15 | duplicate that setting in either chroot alsa config or chroot pulse setup
| |
| 11:15 | probably pulse
| |
| 11:15 | if none of the lts.conf settings are doin it fora
| |
| 11:15 | for ya*
| |
| 11:16 | dro_, we don't use the distro installed pulse configuration with ltsp in the chroot, as it is both different per distro, and wouldn't work by default anyways
| |
| 11:17 | so you would have to modify the init scripts
| |
| 11:18 | <sbalneav> Ahmuck-Sr: Well, file a bug against gdm then :)
| |
| 11:19 | <Ahmuck-Sr> i'm still looking

| 11:59 | <Gadi> dro_: btw, I apologize for being afk. I should have told you to run: alsamixer -c0 in the xterm window
| |
| 12:00 | the -c0 is required, because we currently set pulse as the default alsa sound card even in the chroot environment
| |
| 12:00 | er, localapps environment
| |
| 12:00 | * _UsUrPeR_ makes a mental note about that for the future\ | |
| 12:00 | <Gadi> so, -c0 tell it to run alsamixer on the first real soundcard
| |
| 12:01 | <Brian_H> do you do that in the chroot all the time or can you do it from an ltsp client? (I'm about to setup ltsp for our business here:) )
| |
| 12:01 | dan_young has quit IRC | |
| 12:01 | <Gadi> to find the channels, you can either look in alsamixer, or run: amixer -c0 scontrols
| |
| 12:02 | Brian_H: do what exactly?
| |
| 12:02 | <Brian_H> use the command you specified above to set audio
| |
| 12:03 | <Gadi> the alsamixer command was not to set audio, but rather to run in a localapps xterm window to discover the audio channels on the client
| |
| 12:03 | since dro_ wanted to do some fine-tuning with audio
| |
| 12:04 | in the end, to set the audio levels, he added parameters to lts.conf
| |
| 12:04 | namely, in his case, VOLUME and HEADPHONE_VOLUME
| |
| 12:04 | to fine-tune any audio channel volume, you can use the parameter <channel_name_in_caps>_VOLUME
| |
| 12:05 | the channel name depends on the sound driver
| |
| 12:05 | many sound driver have a "Headphone" channel, for example, but not all
| |
| 12:05 | <Brian_H> ahh ok
| |
| 12:06 | <ogra> more monopols !!!

| 12:15 | <lupine_85> how difficult is it to configure LTSP to use NX?
| |
| 12:15 | my distribution seems to have some packages regarding it for an ltsp /cluster/ - but nothing for a single LTSP server
| |
| 12:16 | <ogra> beyond packages you also need to write a screen script that starts NX ... and set your lts.conf to use that instead of ldm
| |
| 12:16 | <dro_> Gadi: it's all good dude, I'm just glad it's working
| |
| 12:17 | <lupine_85> ogra: righty-ho. so not particularly baked in :)
| |
| 12:17 | <ogra> nope
| |
| 12:17 | i think Gadi once had such a screen script for ltsp 4.x ...
| |
| 12:17 | <lupine_85> (I'm in charge of setting up my work's new LTSP server, and it's on the list of 'nice to have extras if it's not too much hassle')
| |
| 12:17 | <ogra> we should probably include it
| |
| 12:18 | (and port it to 5.x)
| |
| 12:18 | <lupine_85> doesn't ldm facilitate the sound and such as well, though - so one would need to write custom gubbins for all that too?
| |
| 12:19 | (we're really loving the ease-of-use of the current LTSP setup. works great out of the box)
| |
| 12:19 | <ogra> likely for a bunch of stuff, yes
| |
| 12:19 | <lupine_85> although it shocked me a bit to discover that a youtube video expands to ~150Mbit/sec over the local network!
| |
| 12:19 | <ogra> sound might be easy, i think NX cares for it
| |
| 12:19 | <lupine_85> that's X for you, I guess
| |
| 12:19 | <ogra> local devices or local apps will be tricky to achieve
| |
| 12:20 | <lupine_85> yeah, we like localdevices very much and, for what NX gives us, we can probably use LocalDevices instead
| |
| 12:20 | <ogra> you should use localapps for youtube
| |
| 12:20 | <lupine_85> erm, localapps
| |
| 12:20 | yeah
| |
| 12:20 | <ogra> right
| |
| 12:20 | <lupine_85> Java applications as well - nasty
| |
| 12:20 | welll. nastier
| |
| 12:20 | <ogra> if you use firefox on the server the yourtube strem is decompressed on the server indeed
| |
| 12:21 | <Gadi> lupine_85: are you using DIRECTX?
| |
| 12:21 | <ogra> so the 30fps go over the thin client network uncompressed
| |
| 12:21 | <Gadi> er, LDM_DIRECTX
| |
| 12:21 | <lupine_85> yeah, LDM_DIRECTX and we disabled compression too
| |
| 12:21 | <Gadi> have you tried:
| |
| 12:21 | !flash
| |
| 12:21 | <lupine_85> we've got twelve cores to play with but didn't really want sshd to take an entire one for itself ;)
| |
| 12:21 | <ltspbot> Gadi: "flash" is Yes, flash sucks. Make sure you have LDM_DIRECTX=True in your lts.conf file, or if it's just youtube you're after, try the HQtube plugin. Install greasemonkey for firefox, and see http://userscripts.org/scripts/show/24999
| |
| 12:22 | <lupine_85> hmm. HQTube has an interesting top result in google... :p
| |
| 12:22 | <Gadi> short of running firefox as a local app, the above seems to be one of the few server-based ways to tame flash
| |
| 12:23 | <lupine_85> we're fine with getting into localapps more, I think
| |
| 12:24 | ta for the insights

| |
| 13:24 | <alkisg> Is mythbuntu special, as far as ltsp is concerned? Or is it just like ubuntu?
| |
| 13:25 | <vagrantc> i seem to recall it having some particular LTSP tweaks
| |
| 13:25 | laga was the one who worked on it
| |
| 13:26 | <staalej> i just upgraded to 9.10, and they removed the graphical way of configuring it
| |
| 13:26 | and there is supposed to be a special 030-mythbuntu plugin
| |
| 13:27 | which is needed to build a new file tree under /opt/ltsp/i386
| |
| 13:28 | Ahmuck-Sr has quit IRC | |
| 13:28 | <staalej> mythbuntu is basically ubuntu with some extra packages
| |
| 13:28 | <Lns> I know there's an ltsp-build-client --mythtv (or similar) switch
| |
| 13:29 | <staalej> lacking the graphical choice, i'm trying to use excactly that
| |
| 13:29 | erm, exactly
| |
| 13:30 | https://help.ubuntu.com/community/MythTV/Install/Hardy/Diskless
| |
| 13:32 | <johnny> the mythbuntu plugin is in there
| |
| 13:32 | just open up the file and see what option you need to pass
| |
| 13:34 | <Brian_H> whats the best method of installing ltsp on ubuntu? Installing via the server then the packages or installing the desktop edition as a server? I want the users to have the best "desktop experience" possible
| |
| 13:34 | <alkisg> Brian_H: using the alternate CD, and pressing F4 and "install an ltsp server" while booting.
| |
| 13:34 | <Brian_H> simple enough :D
| |
| 13:36 | <staalej> johnny: the docs say it should need --keep-mythbuntu-user-credentials, but my 030-mythbuntu plugin has no such option
| |
| 13:37 | <johnny> notice that that docy ou linked says HARDY
| |
| 13:37 | where is laga when you need em
| |
| 13:37 | <staalej> :-)
| |
| 13:38 | <johnny> perhaps just try installing whatever option you need that you see
| |
| 13:38 | in 030-mythbuntu
| |
| 13:38 | and see how it works out
| |
| 13:38 | <staalej> it seems there is a new version of the plugin floating around, but it is not easy to find
| |
| 13:38 | <johnny> the plugin is in ltsp proper

| 13:51 | <johnny> Lns, it's what people are talking about

| 14:10 | <squarepeg> Gadi: any bright ideas why a tftp download would just quit at packet 1229?
| |
| 14:11 | <Gadi> ah... packet 1229....
| |
| 14:11 | :)
| |
| 14:11 | <squarepeg> 1229
| |
| 14:11 | Balls!
| |
| 14:11 | 12229
| |
| 14:11 | <Gadi> oh!!! packet 12229...
| |
| 14:11 | <squarepeg> now he sees
| |
| 14:12 | <Gadi> perhaps it is downloading something too large
| |
| 14:12 | ?
| |
| 14:13 | <squarepeg> hmmm it is the vmlinux for powerpc..
| |
| 14:14 | shawnp0wers has quit IRC | |
| 14:14 | <Gadi> vmlinux or vmlinuz?
| |
| 14:15 | <squarepeg> just doublechecking
| |
| 14:15 | pretty sure vmliux
| |
| 14:15 | Carp!
| |
| 14:16 | yep vmlinux.. 8090626 bytes
| |
| 14:17 | <Gadi> perhaps 8MB is just too much
| |
| 14:19 | <squarepeg> maybe..
| |
| 14:19 | * squarepeg cliebow looks at inetd | |
| 14:19 | <Gadi> how much per packet?
| |
| 14:20 | <squarepeg> ill run again
| |
| 14:21 | pmatulis has quit IRC | |

| |
| 15:29 | <_UsUrPeR_> Gadi: question answered. Thanks for your time.
| |
| 15:29 | <Gadi> hehe
| |
| 15:29 | so formal
| |
| 15:29 | :)
| |
| 15:30 | also, due to the lack of an integrated dbus, there is no way for the desktop environment to unmount the device directly
| |
| 15:33 | <johnny> for now..

| 15:47 | <_UsUrPeR_> Gadi: any luck with using localapps with mounted USB drives?
| |
| 15:48 | <Gadi> _UsUrPeR_: you could cheat
| |
| 15:48 | :)
| |
| 15:48 | <_UsUrPeR_> yeah, yeah :)
| |
| 15:49 | that makes me feel really dirty though :)
| |
| 15:49 | knipwim has quit IRC | |
| 15:49 | <Gadi> one cheat is: ln -s /media/$USER ~/Drives on login
| |
| 15:49 | and tell your users to go to their Drives directory
| |
| 15:49 | <_UsUrPeR_> Gadi: Oh, I thought you were talking about copying the file to the desktop
| |
| 15:49 | <Gadi> another cheat is to see if installing ltspfs in the chroot helps
| |
| 15:50 | but, the latter was not fleshed out enough for local apps, I believe
| |
| 15:50 | so, the first cheat is the better one for now
| |
| 15:50 | specially if ur a user
| |
| 15:50 | :)
| |
| 15:51 | remember, we use sshfs
| |
| 15:51 | which, by default on Ubuntu, follows symlinks
| |
| 15:51 | ;)
| |
| 15:51 | now, aside from the fact that the files have to go over the network twice ... :p
| |
| 15:51 | <_UsUrPeR_> true
| |
| 15:52 | <Gadi> its a quick cheat
| |
| 15:52 | for those inclined to cheat
| |
| 15:52 | <vagrantc> follows symlinks ... i.e. an sshfs mounted homedir with a symlink outside of the home dir will point to files on the server?
| |
| 15:52 | <Gadi> vagrantc: sure
| |
| 15:52 | its a wacky world out there
| |
| 15:52 | :)
| |
| 15:53 | <sbalneav> Gadi: I beleive I've found the "correct" way of handling the perms problem.
| |
| 15:53 | <Gadi> sbalneav: a hair dryer and curlers?
| |
| 15:54 | <sbalneav> We'll have ltspfs "mangle" the perms in the _getattr call, and not pass through real perms, unless a command line switch is added.
| |
| 15:54 | <Gadi> sounds about right
| |
| 15:55 | <sbalneav> I have some free time tonight. If I updated the upstream code, could you roll a package and test?
| |
| 15:55 | <Gadi> Ill let you know in a few minutes - I am actually building a karmic VM on the old ESX server atm
| |
| 15:55 | <_UsUrPeR_> another unfortunate circumstance pertaining to USB drives: how user groups affect what people can see mounted.
| |
| 15:56 | it really complicated an LDAP installation :P
| |
| 15:56 | <Gadi> _UsUrPeR_: thats what we aim to fix
| |
| 15:56 | just remember, its all your fault
| |
| 15:56 | :)
| |

| 15:58 | <sbalneav> The last thing we need is people coming in here with a hacked system because they've installed setuid perl, and now every kid on their system's pwned their server.

| 17:04 | <Brian_H> hmm, after a fresh install from ubuntu 9.10 alternate and selecting "ltsp server" from boot, I can not get clients to boot off the server, my clients get a dhcp address and I can watch the tcpdump on the ltsp server and see the tftp request but the client never boots. Can anyone maybe throw a hint my way?

| |
| 19:51 | sbal
| |
| 19:52 | <sbalneav> Just assign the profiles by user.
| |
| 19:52 | <dtrask> sbalneav: do I need to remove something? In other words I have 3 users...each had logged in before. Then I create new profiles for each with Sabayon....but they don't seem to be working...the changes I made aren't sticking...
| |
| 19:54 | <sbalneav> stgraber: sent
| |
| 19:54 | By default, most of what goes on in sabayon are "defaults", you'll have to mark the changes as "manditory" in the config editor.
| |
| 19:55 | <dtrask> sbalneav: ah....the student one is working....now to see if teacher and eventually admin....or is the admin user kinda' exempt?
