Morning all
08:54
<Appiah>
hello
08:55
<CAN-o-SPAM>
hey sbalneav
08:56Brian_H has joined #ltsp
08:58rjune has quit IRC
08:59
<Appiah>
is italc still under development?
08:59rjune has joined #ltsp
09:01bieb 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
09:14Brian_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
09:14Brian_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
09:15squarepeg 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
09:16ogra_ 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...
09:17ogra 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
09:25ogra_ has quit IRC
09:25ogra 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?
09:29Egyptian[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
09:34artista_frustrad has quit IRC
09:37
<Appiah>
sbalneav: the log looks exactly the same
09:37artista_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
09:41rjune_ has joined #ltsp
09:41
<Appiah>
i inserted that text that you pasted
09:41
3 lines
09:41Ahmuck-Sr has joined #ltsp
09:42
<Appiah>
oh wait
09:42adrien 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.

09:45
<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 =/
09:59tstafford_ has joined #ltsp
09:59
<sbalneav>
ok, but lets see the log now.

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
10:09

10:10dan_young has joined #ltsp
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...

<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>

sbalneav: all my users are on a long list at the server

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?

No. Not that I know of

_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 :)

<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:) )
12:01dan_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

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

you have to mv chroot chroot.bak

after installing a new chroot

only server side config is changed.. nothing in the chroot

laga was the one who worked on it
13:26

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

which is needed to build a new file tree under /opt/ltsp/i386
13:28Ahmuck-Sr has quit IRC

mythbuntu is basically ubuntu with some extra packages

lacking the graphical choice, i'm trying to use excactly that

13:30
https://help.ubuntu.com/community/MythTV/Install/Hardy/Diskless

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

notice that that docy ou linked says HARDY
13:37
where is laga when you need em

perhaps just try installing whatever option you need that you see
13:38
in 030-mythbuntu

and see how it works out

it seems there is a new version of the plugin floating around, but it is not easy to find

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

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.
15:59
<Gadi>
sbalneav: just don't write the companion wikidoc of how to exploit suid-perl
16:00
:)
16:00
<_UsUrPeR_>
gadi: holy crap
16:00
I'm going to have to test that out
16:00* Gadi wonders why nobody looks at the wiki
16:00
<Gadi>
:)
16:01
<_UsUrPeR_>
I did! His name is Gadi! ;D
16:01
<Gadi>
hehe - thats why I write these things so infrequently, that I inevitably screw something up on the wiki

<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?

sbalneav: hey...tried sabayon...how do I get the system to use the profiles over the ones that were there?
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?

Shouldn't be.
