after booting the clients every once in a while the keyboard doesn't react anymore - we cannot even switch NUM on or off or so. Stuck at ldm and only option is to reboot 1-5 times so it will work again. any ideas?

<johnny>
sounds like some sort of kernel panic
02:04
well.. one suggestion would be add an ssh server on your client chroot
02:04
and then ssh into it
02:05
see if you can get to it, if you can.. then you read logs while you trigger the failure

johnny, sorry had another problem to take care of; why do you think it could have something to do with ssh?
04:28
my problem seems similar to that bug: https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/58981
04:29
but on some clients a ps/2 works just fine and on some i need to reboot several times until it works
04:29
-> stuck at login screen (ldm) and cannot even switch to terminal or so ..
04:33
<masus>
hi all , have one server with debian amd64 and want to connect from one client but get an message like "Your CPU does not support long node.Use a 32Bit Distribution"
04:33
can anybody help ? Thanks

keyboard dies on login screen: http://www.omgili.com/mailinglist/debian-edu/lists/debian/org/BAY105-W2470842C1C2ED56844EB90A2350phxgbl.html - - - all the values are set to default (no lts.conf exists), so i don't know how that "SCREEN_01 = startx" thing could be the issue here?
04:44
<johnny>
masus, that means you need to use ltsp-build-client --arch=i386
04:44
Briareos1_, i said you could use ssh to discover the problem
04:45
by logging into it remotely
04:45
<Briareos1_>
johnny - i am logged in via ssh
04:45
<masus>
i have do before only ltsp-build-client. do ┼čahve to uninstall it before ?
04:45
<Briareos1_>
johnny but what exactly could i look for?
04:45
<johnny>
to the client?
04:45
<masus>
johnny: *do i have to uninstall it before?
04:46
<johnny>
masus, i don't think so
04:46
it uses different directories
04:46
Briareos1_, logs ?
04:46
<masus>
johnny: ok thank u very much ...
04:46
<johnny>
or see if ssh freezes. or just the display
04:46
or rather.. just the keyboard
04:49
<Briareos1_>
johnny ah okay sorry - you mean ssh'ing to the client - not the server; well as the problem is not "active" at the moment I can't
04:49
<johnny>
well you would still have to rebuild your chroot , since it isn't there by default
04:49
you would have to install the openssh-server package
04:49
it is 6am for me.. i must go to sleep
04:50
but i'll be back later i'm sure
04:50
<Briareos1_>
k sleep well :)

my keyboard "dies" when reaching the login screen. No input possible. Only with PS/2, but on the other hand not on all clients. Any ideas how to fix that?

WITHIN the ltsp client i start a Citrix ICA terminal window to connect to a windows NT4 TS. Problem is: Sometimes that window doesn't get refreshed correctly. any idea?
08:45
windows are then blurred and shifted and one cannot really work like that
08:45
(on that winNT-TS is our main accounting software)
08:45
<ogra>
did you ask citrix ?
08:46
<Briareos1_>
nope. i suspect ltsp to be the problem here (on normal client it works well - same version)
08:47
<ogra>
are you 100% sure it's the same X version ?
08:47
<Briareos1_>
maybe it doesn't recognize that there is something to refresh within that window (though I admit i have too little knowledge - just know that from VNC)
08:47
ogra - no - i meant the same ica client version
08:47
<ogra>
right
08:47
i suspect its not compiled against the current X libs
08:48
<Briareos1_>
hmm it came as a ready package
08:48
<ogra>
how old ? when was it built
08:51
<Briareos1_>
gotta check - by the way: one employee is working more with using the mouse and the other merely uses the keyboard -> the problem is worse when using keyboard only to switch thru the windows in the TSC
08:53
ogra: the ica clientsoftware is from June 2007

Hello, i'm having trouble to login on ltsp 5 client. I have tested with the command "X -broadcast" on client and then, showed the gdm screen and i have logged in. But, with the login screen of the ltsp 5, i inform the user and password, get the message "Verifying password. Please wait...". Then the background goes black (but i can see the mouse cursor) and, after 3 seconds the X server restart
12:14
<Lns>
juanpaul, well i'm not sure why you're doing an 'X -broadcast' since LTSP does a full boot from PXE on the client - but the 3 seconds/x restart is usually because the user typed in a wrong password
12:22elisboa has joined #ltsp
12:33
<juanpaul>
Lns, i'm doing 'X -broadcast' to connect on the server GDM via xdmcp and, it worked ok. Isn't wrong user/password because i can log via xdmcp. I've retyped the password many times (one user password is '1234')
12:36
<Lns>
juanpaul, i might be missing something but what do you mean by being able to 'log in' via xdmcp? xdmcp is the protocol to connect to a login manager (at least afair)
12:36
do you mean log in via the server console?
12:39
<juanpaul>
Lns, i call the X -broadcast on ltsp client, then it found my X server on the main server, connect to it and show the gdm login screen, using this i can authenticate the user (logon on gnome, show menus, everything appears to be ok) that i've created to be accessed via ltsp client.
12:39
but via LTSP way not go
12:40
i'm using Gentoo
12:41
<Lns>
juanpaul, hmm - well ldm should authenticate the same way as gdm... unless you have some weird setting in your lts.conf ..? Not sure, never encountered that issue before
12:41
actually
12:42
have you changed server IP addresses?
12:42
might want to try ltsp-update-sshkeys
12:42
<johnny>
why are you using gdm ?
12:42
if it doesn't work.,. you're kinda on you're on juanpaul .. i haven't touched anything but making ldm work
12:43
ldm is the only thing i will make adjustments for atm
12:43
Lns, how would ldm auth the same was as gdm?
12:44
it's somewhat similiar.. but ldm makes a direct external ssh connection
12:44
<Lns>
johnny, via pam ?
12:44
<johnny>
sure.. but one happens directly on the server itself, and one happens from afar
12:44
and via different pam path
12:45
<Lns>
so it's an ssh issue i would assume..?
12:45
<johnny>
what he's trying wont' work with ssh
12:45
just xdmcp
12:45
<Lns>
no, he says he can login via xdmcp, right?
12:46
<juanpaul>
yes, i can login via xdmcp
12:46
<johnny>
well.. don't :)
12:46
<Lns>
just not via "ltsp" (I'm assuming via the full pxe boot)
12:46
<johnny>
ok
12:46
messages were confusing
12:46
<juanpaul>
johnny, i will use the local screen of this server as an X terminal too
12:47
<Lns>
yea the xdmcp is a weird route but it does prove that the pw isn't wrong
12:47
<juanpaul>
here is the ldm.log output: http://www.pastebin.org/44000
12:47
<Lns>
juanpaul, did you change IP addresses of the server?
12:47
<johnny>
juanpaul, check your server logs for ssh
12:47
see what happened
12:48
<juanpaul>
Lns, no. I can login ok from ltsp client to server using ssh
12:48toscalix has quit IRC
12:48
<johnny>
juanpaul, does it ask you any questions?
12:48
other than the password
12:49
<juanpaul>
no
12:49
<johnny>
if it says anything but the password, it will have problems.. like asking you whether you trust the host
12:49
when connecting to a new server
12:49
Lns, he's testing the alpha version of ltsp5 for gentoo, first person other than me to ever use it
12:49
<Lns>
ooooh
12:49
;)
12:50* Gadi thinks ldm tries to run /etc/X11/Xsession which you do not have
12:50
<juanpaul>
johnny, no, only ask for the password. This seems that know_hosts is OK
12:51
i've found this message on sshd log: debug1: x11_create_display_inet: Socket family 10 not supported
12:51
<johnny>
Gadi, how would you know that? :)
12:51
<Gadi>
ldm.log he pasted
12:51
expect saw: sh-3.2$ Warning: No xauth data; using fake authentication data for X11 forwarding.
12:51
expect sees a shell prompt
12:51
<johnny>
hmm.. i think i still get that warning
12:51
and it works
12:52
<Nubae>
anyone here heard about usb based thin clients built into monitors?
12:52
using displaylink technology... I've seen a video that claims they are doing ltsp that way, but find it hard to believe
12:52
<johnny>
juanpaul, do you have the xdm package installed?
12:53
<juanpaul>
Gadi, i've linked /etc/X11/Xsession to /etc/X11/Xsession/Sessions/Xsession on the server
12:53
<johnny>
that won't work i think juanpaul
12:53
remove that
12:53
install xdm instead
12:53
it includes a session chooser shell script
12:53
i thought i made that mandator
12:53
mandatory*
12:54
<juanpaul>
johnny, i don't have xdm installed, beside, i have gdm installed
12:55
<Nubae>
http://www.ndiyo.org/systems/hubster/basics
12:55
<johnny>
you need xdm
12:55
<Nubae>
is that possible?
12:55alkisg has quit IRC
12:55
<johnny>
that's the conclusion dberkholz and i came to, at least in this juncture of the current gentoo xorg setup
12:55
i should see what outstanding patches i have
12:56
looks like none..
12:56
guess i need to make ldm a required dep on the server
12:56
<Nubae>
I see this part as being highly unlikely: Our software can explore the hierarchy of the USB connections, work out which components are connected to which hubs, and automatically make intelligent decisions about how to group them into terminals.
12:57
<johnny>
Nubae, that seems feasible
12:57
they all have usb ids..
12:57
they are all connected to specific root hubs
12:57
<Nubae>
so u think they'll automatically route?
12:57
<johnny>
it is feasible
12:57
<juanpaul>
johnny, ok, uninstalling gdm and installing xdm
12:57
<Nubae>
hmmm... well then its damn interesting
12:57
<johnny>
don't know if their stuff does
12:57
juanpaul, i didn't say that
12:57
you do need xdm is all i'm saying
12:58
doesn't mean you need to uninstall gdm
12:58
<Nubae>
for 5-10 client setups it would be amazing...
12:58
<johnny>
Gadi, there's a patch in ldm specifically for gentoo, to match the hacks for other locations for other distros
12:59
juanpaul, i'll be in and out, it is my work day
12:59
so don't expect instant responses
12:59
but i will be around at various times, so you should probably idle in this room until we get it worked out
13:00
<Nubae>
still the hardware vendors only mention multiple monitors on one system... but it could be tested easy enough
13:00
<juanpaul>
johnny, ok, no problem
13:00deavid has quit IRC
13:00
<johnny>
Nubae, gimme the system with 30 usb ports :)
13:00
:)
13:01
Nubae, i've seen how flexible udev is.. so i'm sure amazing feats are possible
13:01
juanpaul, got xdm yet?
13:01* johnny anxious to know what happens
13:02
<Nubae>
hmmm... how come this is the first I've ever heard of this... its not mentioned anywhere... and seems so simple
13:02Gadi has quit IRC
13:02
<Nubae>
and they mention wireless usb!! now that would be cool
13:02
<johnny>
wireless usb is happening..
13:03
nice patches coming into the kernel to control security of such external devices
13:03
initially brought about by wireless usb necessities for controlling what you can and can't hook up to the system
13:03
<Nubae>
so totally wireless thin terminals for almost no cost... the mind boggles
13:03
<juanpaul>
johnny, it's compiling (it's a Celeron 500...). I'm installing xdm-1.1.6
13:03
<johnny>
Nubae, don't forget about the batteries
13:03
i wouldn't use wireless keyboards
13:04
or mice
13:04
<Nubae>
I can sell this to OLPC :-)
13:04
they've been against ltsp because of the wired aspect
13:04
<johnny>
the price point isn't there yet for the wireless usb
13:04K_O-Gnom has quit IRC
13:04
<Nubae>
true
13:04
<johnny>
eventually yes.. just not now
13:04
<juanpaul>
johnny, WoW great, it's working.
13:04
<johnny>
juanpaul, i'll update my ebuilds later today
13:04
<Nubae>
still, if the terminals are next to each other, being able to dump ethernet is a good selling point
13:05
do you know anyone who has tried that kind of setup johnny?
13:05
<johnny>
wait.. then pxe won't work
13:05
i didn't notice you say anything about the network being wireless..
13:05
juanpaul, so.. you're logged into gnome and editing stuff?
13:05
or doing stuff?
13:07Gadi has joined #ltsp
13:08
<juanpaul>
johnny, i'm get logged into my gnome session. It's working like i've running the programs on the server. Now, lets set lts.conf
13:10
<johnny>
set lts.conf for what
13:11
you're about to expose something :)
13:11
none of the X_ stuff except X_CONF works
13:11
cuz the configure-x script keeps crashing
13:11
so CONFIGURE_X defaults to off for now
13:11
you're venturing into more uncharted territory.. past where even i've gone :)
13:12
i've only tested a few parameters
13:12
dberkholz, looks like stuff works :)
13:13
so.. i guess soon i'll keyword this stuff ~x86 then :)
13:13
<juanpaul>
johnny, i need to lower the screen resolution (my monitor isn't DPMS capable)
13:14
<johnny>
uhmm... that's not supported atm
13:14
unless you can figure out why the configure-x crashes
13:14
you can force enable it by setting CONFIGURE_X=T
13:15
right now it defaults to using xorg's own config generation
13:15
dberkholz, so.. we have success
13:15
juanpaul, i updated the ltsp-server ebuild to require xdm
13:18
<juanpaul>
johnny, sorry. English isn't my native tongue. Are you saying that the lts.conf have being ignored by the ltsp client?
13:24
<johnny>
no.. saying that all the X_ stuff will be ignored
13:25
<juanpaul>
johnny, so i can pass this option 'X_MODE_0 = 800x600' with 'CONFIGURE_X_MODE_0 = 800x600'

cvergara: is the user a member of the "fuse" group?
13:34
<cvergara>
yes
13:34
<Gadi>
is the "fuse" module loaded on the server: lsmod|grep fuse
13:34
<cvergara>
in xterm right?
13:34
<Gadi>
yes
13:35
on the server
13:35
or through your session
13:35
<cvergara>
yes, its loaded
13:35
<johnny>
juanpaul, no.. you can't
13:35
juanpaul, they don't work unless you can make CONFIGURE_X itself work
13:35
<Gadi>
cvergara: do you have ltspfs installed?
13:35
<johnny>
you can see if it crashes your thin client like it did mine by CONFIGURE_X=T
13:35
<cvergara>
yes I have
13:35
<johnny>
but that option is required for the X_ variables to work
13:35
<Gadi>
is it a partitioned USB drive?
13:36
<cvergara>
yes, it is
13:36
<Gadi>
ie, does it have a single FAT partition?
13:36
<johnny>
juanpaul, it's two seperate parameters
13:36
<cvergara>
yes, it worked directly plugged into server
13:36
<johnny>
CONFIGURE_X=T
13:36
X_MODE=yourmode
13:36
<Gadi>
cvergara: that doesnt mean its a partitoned USB drive
13:36
do this:
13:37
<juanpaul>
johnny, ok. changed the lts.conf. Let's see if its work
13:37
<Gadi>
plug it into the server, open a terminal window on the server, run dmes
13:37
make note of the sd device letter (sdc, for example)
13:37
and then do: fdisk -l /dev/sdc
13:37
that should tell you how it is partitioned
13:37
(or if it is)
13:38
<cvergara>
yes, device is /dev/sdc, it has only 1 partition /dev/sdc1, and its a fat16
13:38
<johnny>
Gadi, what should i do if have a like 4 different floppies showing up on my desktop
13:38
it keeps showing fake floppies :)
13:38
and they keep adding up

no, all files are in latin aphabet
13:42
<Gadi>
hmm...
13:42
grep DISPLAY /usr/sbin/ltspfsmounter
13:42
<cvergara>
wait, I'll try something
13:42
ok
13:42
with usb plugged?
13:43
<Gadi>
doesnt matter
13:43
but from an xterm
13:43
if you have a line like "localhost:10", comment that out
13:43
<cvergara>
damn... an error
13:44
It says that doesn't exist..
13:44
<Gadi>
really?
13:44

yes
13:44

13:44
dpkg -l ltspfs

can you list the files in that rpm?

13:48
<cvergara>
Gadi, when i logged into client as root, i can perfectly use usb disk
13:48
i just discovered that
13:49
<Gadi>
try this:
13:49
as root:
13:50
chmod +s /usr/bin/fusemount
13:50
chmod 666 /dev/fuse
13:50
then log in as a normal user
13:51
<cvergara>
IT WORKS!
13:51
:)
13:51
thanks Gadi
13:51
<Gadi>
cvergara: you will need to edit a udev rule to make the /dev/fuse perms permenant
13:51
I will leave that as an exercise for the reader
13:51

Hi all. I'm trying to get local devices working on our Ubuntu thin clients. I found the page at https://wiki.ubuntu.com/DebugLocalDev and followed the steps up until it tells me to write to y'all :) The error I'm getting when I manually issue a mount command is this: /dev/fuse not writable
14:45
<Gadi>

I noticed on that page that I didn't have ltspfs installed

So I installed it
14:47

is it installed now?

(again, on the client)
14:54
<Gadi>
and you were logged in as hallmant thru ldm at the time?
14:54
<hallmant>
yup
14:55
<Gadi>
on the server, can you check the contents of /media/hallmant
14:55
?
14:56

Hmmm... there is no /media/hallmant

just /media/cdrom

how about /tmp/.hallmant-ltspfs

14:57

has the server been rebooted since you installed ltspfs?
14:57
<hallmant>
no
14:57
<Gadi>
go ahead and give it a reboot, if you can
14:58
<hallmant>
Is there a particular daemon I could restart instead? I have a number of users on it right now :-/
14:58

ah, ok
14:58

is fuse loaded?

try that command from the client again
15:00

No dice :-/
15:00
Same error
15:01
I could try a reboot... I'd just have to politely ask a number of folks to take a coffee break
15:01

yeah
15:01
if you could

I think it would clear things up

Hi again... sorry, Gadi... still not working :(
15:15

No, I narrowed it down to something in the kernel, but it was most annoying. I couldn't EVER get it to repeat reliable.
15:15
<Gadi>
elwell642: :(
15:15
sbalneav: I find it happens on certain websites
15:15
<sbalneav>
it would go for days without a problem, then hang up 3 times in one day.
15:15
<elwell642>
I still don't have a /media/hallmant
15:15elwell642 is now known as hallmant
15:15
<Gadi>
it is completely usage-related
15:15
<sbalneav>
It would actually COMPLETELY hose the USB interface.
15:16* Gadi nods
15:16
<Gadi>
hallmant: same error?
15:16
<sbalneav>
Even if you killed udev, manually unloaded all the USB drivers, and restarted udev, it didn't even see that the USB interface was in the machine anymore.
15:16
<Gadi>
sbalneav: a switch to vesa driver seems to clean it up
15:17
so, its definitely the driver
15:17
it sounds to me like it is writing to a place in memory it should not
15:17
<sbalneav>
It must be something really whacky, to completely knock out the USB device
15:17
agreed
15:17
<Gadi>
like the place that holds the USB interface info
15:17
:)
15:17
<hallmant>
Gadi: Same
15:18

I never liked video cards that used systems memory, for that exact reason.
15:18

btw: hallmant is having localdev issues, where it claims his /dev/fuse is not writable when it is
15:18
(ltspfsmounter croaks)
15:19

I followed all the steps on https://wiki.ubuntu.com/DebugLocalDev, and that led me here
15:19

15:19
tell me if you have any localhost:10 lines in there...
15:19
:)
15:20
<sbalneav>
hallmant: ls -l /dev/fuse, and then in a shell window, do an "id"
15:20
<hallmant>
Gadi: that command didn't yield anything
15:21

I don't know if this matters, but my server is a amd64 arch while the clients are i386s
15:24
<sbalneav>
Shouldn't. I notice you've got a VMWARE group. You haven't got a virtual server, do you?
15:24
<hallmant>
Not on this machine
15:25
I get the group stuff from LDAP. I run vms on other servers which also uses that LDAP info
15:25
<sbalneav>
getent group fuse
15:25
then grep fuse /etc/group
15:25
<hallmant>
I'm in the fuse group...
15:26
<sbalneav>
fuse is 107 on my hardy install
15:26
yours is listing 118
15:26
maybe you've got one fuse in /etc/group, and one in LDAP, on different numbers.
15:26
<hallmant>
Ahhhh
15:26
Indeed... it does look that way

Depending on your use case, you might want to:

a) modify the local /etc/group to match ldap
15:29
b) modify your udev rules to set mode of 0666 on fuse.

15:39
<hallmant>
sbalneav: I just logged out and back in
15:39
Should I need to reboot?
15:39
<sbalneav>
Yeah, because it picked that up during the fuse kernel driver install.
15:39
you could just unload the fuse driver
15:39
rmmod fuse/modprobe fuse
15:40
that should recreate the node with the right perms
15:40
Of course, if something's using fuse, then you won't be able to rmmod

16:01

did you do the --config?

after I did --remove /usr/bin/gnome-session

Maybe you have to restart kdm

it said only one choice, nothing to configure when I did --config
16:01
did that too
16:01

then "man kdm" and start readin :)

Nothing seems to happen when I plug something in

I don't use kdm, so I don't know where it's config files are.

x86, by default it uses ldm which is kind of a graphical ssh client
16:07
<x86>
hmm
16:07
<ogra>
all features (i.e. localdev and sound ) are developed towards it
16:07
<x86>
my thin clients only support RDC, citrix, and XDMCP
16:07
don't care about local devices nor sound
16:07
<ogra>
using XDMCP means you will lose these features or have to implement them yourself

<hallmant>
sbalneav: do you have further thoughts for what might be wrong with my local devs?
16:18
<ogra>
hallmant, are you sue you dont see the devices in /media/$USER ? (if youre logged in through a ltsp client
16:18Nubae has quit IRC
16:18
<hallmant>
Yeah... media only contains cdrom
16:19
(and cdrom0, but it's just the symlink from cdrom)
16:19Nubae has joined #ltsp
16:19
<hallmant>
The client is definitely seeing the device... dmesg tells me so
16:20
<ogra>
what releae is that ?
16:20
<hallmant>
Of what?
16:20
<ogra>
(and distro)
16:20
<hallmant>
I'm using Ubuntu Hardy and LTSP 5
16:22
<ogra>
hmm, that should just work
16:22
did yo apply all updates ?
16:22
*you
16:22
<hallmant>
Yup
16:22
I went through the steps of https://wiki.ubuntu.com/DebugLocalDev
16:22
And I noticed that I didn't have ltspfs installed, so I did that
16:23
<ogra>
well, that shouldnt be needed, did you create an lts.conf file ?
16:23
<hallmant>
And then Scott pointed out that I was grabbing the fuse group locally when I really needed my LDAP settings. So I removed the local group and it was looking better, but it's still not working
16:24
I did... but the only special stuff in there is for some dual monitor config
16:24
<sbalneav>
I'll pop in later tonight. Off home for the day.

Yeah... I gotta take off too :-/ I'll stop by again tomorrow morning. Thanks for all your help, folks
16:25
<Gadi>
hallmant: I would have kept the local user and dumped the LDAP user
16:25
<hallmant>
Gadi: Well, I'd love to, but the organization is using LDAP for just about everything
16:26
<Gadi>
*somebody* put fuse into LDAP
16:26
somebody should take it out
16:26
:)
16:26
<ogra>
:)
16:26
<Gadi>
unless you have a user named fuse
16:26
:)
16:27
<hallmant>
haha right... well we were running a Debian server (with LTSP 4.2) for a while and it all worked fine there. So we were hoping to get it working on Ubuntu too
16:27
<Gadi>
you will need to take a look at every file that fuse installed
16:27
and change its ownership to your LDAP's fuse now
16:27
<hallmant>
ohhh
16:27
That's true
16:27
<Gadi>
so, its up to you
16:27
:)
16:28* ogra would like to point out that this is not ubuntu specfic :)
16:28
<hallmant>
Hmmm... is there an easy way to get that list of files?
16:28
<Gadi>
dpkg -L fuse
16:28
er
16:28
dpkg -L libfuse2
16:29
dpkg -L fuse-utils
16:29
<ogra>
fuse-utils ?
16:30
<Gadi>
alternatively, make a note (before you forget) of the local fuse's uid
16:30
er, gid
16:30
:)
16:30
just in case you change ur mind and add him back in
16:30
;)
16:30
<hallmant>
Yeah :) I thought of that, thankfully!
16:30
Thanks guys. I'll try again in the mornin' and let you know how it turns out.
16:30
<Gadi>
system groups in LDAP is BAD
16:31
<hallmant>
Oh yeah?
16:31
<Gadi>
yup
16:31
<hallmant>
Why's that? (I'll pass it along)
16:31
<Gadi>
keep your system groups local
16:31* hallmant is the newbie here :)
16:31
<Gadi>
there is no standard for gids for system groups
16:31
most packages just use the next available one
16:31alekibango has quit IRC
16:31
<Gadi>
when they are installed
16:32
so one machine will have different system groups than another
16:32
<hallmant>
Hmmm
16:32
Makes sense
16:32
<Gadi>
thats why you have different ids for your two fuses
16:33
<hallmant>
Couldn't I just remove the local ones like I did in this case though?
16:33
(that is, why do gids matter?)
16:33
<Gadi>
...if you chown every file that had its id - yeah
16:33
<hallmant>
point taken :)
16:33
<Gadi>
files are never owned by "fuse"
16:33
they are owned by id number "118"
16:34
and 118 is translated to fuse for your benefit when displayed
16:34
<Nubae>
in my ldap, stupid group names reverted to gids, so user john was suddenl 1100
16:34
<Gadi>
if your ldap fuse is 1234
16:34
your file has no idea that it should be owned by 1234
16:34
unless you chown it again
16:34
<hallmant>
But it seems like the downside of that is that I have to add a user to each machine rather than centrally. Though I guess that's pretty normal, huh?
16:35
(Not how it's generally done here.)
16:35
<Gadi>
no - system users are added by the packages that need them
16:35
you would have to add your LDAP users to the local system fuse group
16:35wwx has quit IRC
16:36
<Gadi>
or you can bypass the whole group methodology by making /dev/fuse 666
16:36* hallmant takes notes
16:36
<Gadi>
(ie world writable)
16:36
<hallmant>
right
16:36
<Gadi>
and setuid fusermount
16:36
but, that undermines ubuntu's methodology of using groups to control access
16:36
<hallmant>
right
16:36
<Gadi>
which is why they dont do that
16:36
<hallmant>
thanks much Gadi!
16:36
<Gadi>
np
16:36
<hallmant>
I might be back with more questions, but this is great stuff

Q-FUNK, any update on the geode fun? =)
18:36
<Q-FUNK>
such as?
18:36
<Lns>
Such as not being able to boot into X
18:36
<Q-FUNK>
well, intrepid has newer packages for both -nsc and -geode, which fixes some PCI ID conflicts.
18:37
<Lns>
aha... do you think that's what was causing my issues?
18:37
<Q-FUNK>
but -geode in my PPA should already work for any LX product
18:38
<Lns>
I'm just banging my head because these Koolus were supposed to be ubuntu compatible and I've had nothing but issues with them
18:39
I can't even get LDM (or a tty for that matter)
18:40
stupid rms heh
18:44
<Q-FUNK>
they should indeed work with what's in my PPA, as long as you purge the -amd package after upgrading
18:47
<Lns>
Q-FUNK, so after upgrading to your PPA packages in the chroot I have to apt-get --purge remove the -amd package?
18:47
<Q-FUNK>
yup
18:47
<Lns>
wow well I didn't know THAT... =p
18:47
<Q-FUNK>
then rebuild the boot images
18:48
-amd has just become a transitional package that pulls -geode
18:48
<Lns>
gotcha...
18:52
<vagrantc>
hrm.
18:53
lenny doesn't like my disklessworkstations thin-client + the LCD monitor ...
18:53
<Q-FUNK>
and it will soon be removed, now that Hardy is released and everyone is presumed to have upgrade from -amd to -geode
18:53
<vagrantc>
but i'm actually in position to finally close the usb floppy bug :)

so not really
22:46
this is not the best time for such information
22:46
<a1fa_>
:)
22:46
whats a good time
22:47japerry has quit IRC
22:48
<johnny>
best time is somewhere between 1100 GMT and 2300 GMT
22:49
<a1fa_>
i'll try next time
22:49
:o
22:49
currently i am using an old laptop
22:50
but i'd love something fanless that can be turned on and off
22:50
<johnny>
does anybody sell a thin client for less than 100 that can do what you need?
22:50
<a1fa_>
in a nsap
22:50
i dont need cdrom, floppy and etc
22:50
<johnny>
well.. fanless it could be.. but run your apps.. ?
22:50
<a1fa_>
i thought apps would be run on the server
22:50
<johnny>
depends..
22:51
flash is not friendly over the network :(
22:51
<a1fa_>
really?
22:51
what kind of symptoms?
22:51
<johnny>
choppy video :)
22:51
high memory load on the server
22:51
err high cpu load
22:51
lots of memory being used :)
22:51
but that's flash in general :)
22:51
lol
22:52
if you disable hardware accel, it might work better
22:52
but sadly there's no way you can distrube that change
22:52
it comes from their server
22:52
distribute*
22:52
so you can just preset it in a config file for your users!
22:52
can't*
22:52
uggh.. not a good typing night
22:52
<a1fa_>
i was not planning on streaming flash :P
22:52
would 266 mhz be good?
22:52
<johnny>
uhmm..
22:53
<a1fa_>
hehe
22:53
<johnny>
you should check out the specs of some of the well known thin clients before deciding on that..
22:53
<a1fa_>
how about 1Ghz
22:53
<johnny>
how's your server?
22:53
<a1fa_>
it runs mythbuntu
22:53
allready
22:54
22:53:51 up 2 days, 23:34, 2 users, load average: 1.53, 1.55, 1.53
22:54
model name : AMD Athlon(tm) 64 Processor 3200+
22:54
Mem: 2595928k total, 2524648k used, 71280k free, 15328k buffers
22:54
i can probably soup it up a bit
22:55
4gb of ram*
22:55
<johnny>
well, it just depends on what your users are using
22:55
<a1fa_>
openoffice
22:55
<johnny>
how many users?
22:55
<a1fa_>
two computers running open office
22:55
just two
22:55
<johnny>
two.. you'd prolly be ok :)
22:55
openoffice can easily stomp out your memory
22:55
due to the way they use pixmaps in X
22:56
it's alot better now, if you're using 2.4
22:56
so, that sounds ok
22:57
havent had a problem with openoffice at our location so far
22:58
<a1fa_>
how many desktops on what kind of server?
22:58
<johnny>
uhmm
22:59
4 clients, same proc as yours
22:59
2 gb ram
22:59
but it also does our POS and plays music in the store
22:59
they won't let me make the POS machine a thin client yet
22:59
<a1fa_>
any issues so far?
22:59
<johnny>
a few
22:59
don't have flash working properly yet
22:59
too choppy
23:00
<a1fa_>
i wonder how many people you can load on a quad-core with 8gb of ram
23:00
<johnny>
folks around here would know
23:00
just not me :)
23:00
i can't afford such luxuries
23:00
<a1fa_>
;P
23:00

we're just a small collectively run bookstore coffeehouse
23:00
also poor :)

23:01
its ok :)
23:01
where @?
23:02
<johnny>
baltimore, md , usa
23:02

23:02
mostly book inventory focused tho
23:02
but we sell stuff too
23:02
other stuff*
23:02
like coffee and food
23:03
<a1fa_>
cool
23:03
thats nice that you guys share that
23:05

i wonder how windows terminal server copes with flash
23:08plamengr has joined #ltsp
23:10

that works totally differently tho
23:10
plus it uses rdp
23:11
<a1fa_>
it loads windows ce then it uses rdp?
23:11
is that how that POS works?
23:12

huh?
