did they take out hda_intel_sound of the kernel(?) with 9.04 ?
00:25
or do something different. after some thought, i'm beggining to think it's related to pulse & the intel 82801 sound
00:28
think i've got it finally. pulseaudio which sits on top of alsa. the intel chip is ich2, which does not appear is supported by alsa
00:28

00:47
so it appears that the server kernel has the module for the intel sound. the alsa doesn't show support for 82801BA but does show it for 82801AA
00:47
so i'm hoping that it will work the same
00:48
soo .... do i need to load that kernel module on the server side to get the client to work properly?
00:54
provided i can get sound resolved, the thin clients have ati rage 128 video cards in them. is there a way to utilize the video cards in them?

does anyone know good ways to make firefox lighter? i'm trying to run it as local_app on futro A250 client (geode@500mhz and 256mb ram) and it's quite slow and with youtube it's even slower

hiya
02:46
so like... i cant get the init scripts going on my gentoo system
02:47
do they actually do anything to improve performance? because i can easily log in and run X on my client
02:47
without ldm etc etc
02:51
<nelson__>
this i an interesting question. I read about ltsp-cluster, but i can't figure out what it can give to me that i can't achive splitting my client between the two servers i have

vagrantc: "question" is if you have a question about ltsp, please go ahead and ask it, and people will respond if they can. please also mention the linux distro and release you're using. :)
08:35
<coordinador>
suddenly i lost keyboard layout and gnome theme, and the new configs doesnt take effect
08:35
i rebooted
08:35
i logon as root
08:36
but cannot change config, even i checked with gconf editor and there appeared es,latam (correct) but it just doesnt take effect
08:37
im desperated since yesterday and people will come, i ve searched in web but cannot fix it, i really dont know what it should be
08:39
and i ve just discovered that i cannot put the keyboard layout thing in the panel because it crashes
08:40
my ubuntu is 9.04 and its fully updated
08:41
this is the element> OAFIID:GNOME_KeyboardApplet
08:43
<alkisg>
coordinador: this isn't really an ltsp question, but anyway, why do you use the gnome keyboard layout instead of using sudo dpkg-reconfigure console-setup ?
08:43
The latter affects all users, not only the current user...
08:44
<coordinador>
ill check with that command
08:45
i selected international 105keyboard and i got
08:45
Unsupported settings in configuration file
08:45
:s
08:45
"The configuration file /etc/default/console-setup specifies a keyboard layout and variant that are not supported by the configuration program."
08:46
<alkisg>
coordinador: upload this file to pastebin
08:46
!pastebot
08:46
<ltspbot>
alkisg: "pastebot" is The LTSP pastebot is at http://pastebot.ltsp.org. Please paste all text longer than a line or two to the pastebot, as it helps to reduce traffic in the channel. A link to the content will be pasted in the channel.
08:47
<coordinador>
ok
08:48
<ltsppbot>
"coordinador" pasted "/etc/default/console-setup" (49 lines) at http://pastebot.ltsp.org/459
08:50
<coordinador>
alkisg, done.
08:51
<alkisg>
coordinador: moment...
08:55
ok, back
08:55
coordinador: I don't know what the typical settings for "es" are
08:55
How do you change languages? E.g. in greece we use alt+shift...
08:56
So for me, XKBOPTIONS="grp:alt_shift_toggle,compose:menu,grp_led:scroll"
08:56
<coordinador>
ive never done that, is that configuration bad?
08:57
<alkisg>
I don't know, but it's something that dpkg-reconfigure console-setup doesn't know about
08:57
<coordinador>
there is something wrong in the file?
08:57
i think 'es' is for spanish
08:58
is it bad configured, i ve never touched that file
08:58
?
08:58RobertBerger has joined #ltsp
08:59
<alkisg>
Do you usually use alt+shift to change between es / us ?
08:59
<matttttt>
is there anything faster than nxagent for slow links?
08:59
is nomad or rdp any faster? or do they require less bandwidth to be usable
08:59
we have a few sites that we'd like to have clients at that are connected by t1, my tests using 1 client over a full t1 (simulated between to netopias @ 1.54mbit) is painfully slow.
09:00
<coordinador>
alkisg, i ve never used that, i dont need us keyboard layout
09:00
ive discovered another thing, ill use pastebin, i think thats the problem
09:00
<matttttt>
enabling nxagent didn't even make a perceptable difference in performance
09:00
and it takes like 5 minutes for a client to boot :(
09:01
<ltsppbot>
"coordinador" pasted "after execute gnome-settings-daemon in console" (11 lines) at http://pastebot.ltsp.org/460
09:01
<alkisg>
(04:35:20 μμ) coordinador: but cannot change config, even i checked with gconf editor and there appeared es,latam ==> what is "latam" ?
09:01
<coordinador>
latam is latin american keyboard layout
09:02
<alkisg>
So you do need to switch between 2 keyboard layouts. What keyboard combinations do you use to switch?
09:02
<coordinador>
this configuration was set by keyboard configuration application automatically, not by hand
09:02
check what ive pasted
09:03devilbues has joined #ltsp
09:04
<coordinador>
when i run gnome-settings-daemon, besides this error, the configuration takes effect for half a second
09:05
(the theme configuration, ive not checked the keyboard configuration but the problem could be generated by the same cause)
09:05* alkisg leaves this for someone that has actually used a spanish layout
09:05
<alkisg>
But coordinador you'd better ask in #ubuntu, this isn't ltsp specific...
09:05
<coordinador>
ok, ill do, thanks for all, you guided me

is enabling nxagent the same thing as: http://www.ltsp.org/twiki/bin/view/Ltsp/FreeNX ?
10:12
that page is quoted saying "because protocols used by FreeNX are extremely efficient you can use it to access an LTSP server over a remote WAN access. Some people have also stated that the performance is more than acceptable over dial up." uh, i just tried 1 client over a dedicated t1 with no other traffic happening and it took over 5 minutes to boot and was almost unusable it was so slow once logged in, am i missing something?

hi
10:22
<alkisg>
I'm using nfs for the first time, I just tried "cp -a <some-local-folder-with-6-gb> <nfsshare>". That's on a 100 mbps network. I'm waiting for 5 minutes, how slow is nfs?!!!
10:32
<rjune_>
can be pretty slow
10:36nelson__ has quit IRC
10:38l0C0 has quit IRC
10:39
<alkisg>
Well, 20 minutes later, still waiting :( Can I use <ctrl+Z; bg> or will that break the transfer?
10:39coordinador has quit IRC
10:44
<rjune_>
you can use it
10:45
<alkisg>
thanks, rjune_ :)
10:45
<rjune_>
I think cp -av would clue you in where it was
10:45
where it is.
10:45
Look up performance nfs, IIRC, setting noatime on nfs is a big perf boost
10:46
but yeah, NFS is pretty slow usually.
10:46coordinador has joined #ltsp
10:46
<alkisg>
Ah, I'll try that, though my files are extremely large so I don't think it'll have any boost
10:46
I.e. 100+ Mb each
10:46
<rjune_>
Ah, probably not then.
10:46
still, google nfs performance.
10:46
there's probably a bit you can do
10:46
<alkisg>
I tried another ssh shell, and `ls`, and it stuck there
10:47
<rjune_>
it will
10:47
are you doing cp from local to the nfs mount?
10:47
<alkisg>
Does the copy need to finish before any other requests are served?
10:47
Yes
10:47
<rjune_>
Usually for big transfers like that I use rsync over ssh or scp
10:47
<Lumiere>
yea
10:47
rsync over ssh is the best way
10:47
<rjune_>
nfs is in the kernel, so it'll block things in strange ways.
10:47
<Lumiere>
cause if it fails
10:47
you just kill it and restart
10:47
and it picks back up
10:48
<rjune_>
alkisg: rsync -Wav --progress -e ssh /path/to/src user@server:/path/to/dest
10:48
<alkisg>
Yeah, the problem is that I have limited access to the other machine, all I could convince the admin there to give me was this louzy nfs share :(
10:48
<rjune_>
Ugh.
10:48
<Lumiere>
wait
10:48
they'll give nfs
10:48
but not ssh?
10:48
<rjune_>
Still, in general I prefer rsync to do copies.
10:48
<alkisg>
Yup :)
10:48* Lumiere attempts not to fall over laughing
10:49
<rjune_>
rsync -Wav /src /dest
10:49
<alkisg>
I don't even have an account there
10:49
<rjune_>
alkisg: you have to have something, NFS requires a unix id
10:49
<alkisg>
It's the "web server" for a repository I'm trying to set up
10:49
rjune_: guess so, but I wasn't notified of any passwords or other login data
10:49
<Ahmuck>
u have a trust issue
10:50
<rjune_>
you won't have a password. just a uid.
10:50
<Ahmuck>
u'll need to resolve that first
10:50
<rjune_>
though they may be doing anonymous nfs
10:50
<alkisg>
rjune_: Hmmm ok, can that uid help me somehow?
10:50
<rjune_>
nope
10:50
it's used by the server for permissions
10:50
<Ahmuck>
trust issues can be ok, provided they are not arcane. however i've found where there are trust issues, i normally don't work for that company if those trust issues are inhibiting my ability to get the job done
10:51Gadi has joined #ltsp
10:51
<Ahmuck>
anywhwo. so i think i may have stumbled upon my sound issue
10:51
<alkisg>
Ahmuck: I don't really need/want an account to their web server... It's just that I didn't know nfs was so slow. I'd ftp the files for the first time and use nfs later, if I knew that..
10:52
<Ahmuck>
i think it's intels 80210 chipset
10:52
from what i can gather, the kernel module is on the server, but 1. i've never inserted a module, and 2. should this be done server side or client side?
10:54
what bugs me, is that this is the second round of "older" computers that i've tested, and something's usually broke in 9.04. this causes me concern that ltsp may not be the mouse's cheese party as one might suppose
10:55
hrm, looks like i killed the conversation. /me needs to do some paperwork ...

11:04* Gadi waves, pondering the spread at a mouse's cheese party
11:07RobertBerger has joined #ltsp
11:08
<matttttt>
hmm, appaently enabling nxagent w/ ltsp is not the same thing as full on freenx server/client, this thing is completely usable over my slow wan link.
11:08
shame i can't make ltsp be that usable
11:09* vagrantc waves to Gadi
11:10
<Gadi>
matttttt: there is a difference between connecting to an LTSP server over NX and booting a thin client from an LTSP server over a t1 line
11:11
<ogra>
Gadi, what ?!?
11:11
unbelivable :P
11:11
<matttttt>
well, the bootup process doesn't concern me, i know it's going to be slow unless i have pxeboot servers on the local side of the slow wan link for each remote site that uses a t1, however
11:11
the actual performance of the session is amazingly fast w/ freenxserver as apposed to ltsp
11:11
<Gadi>
sure
11:12
well, no you need to rephrase
11:12
its amazingly fast compared to X-over-ssh
11:12
<matttttt>
well, yes.
11:12
that did need rephrasing :0
11:12
<Gadi>
you can always boot the thin client with LTSP and have it run nxclient
11:12
instead of ldm
11:13
but, you would still be booting over a t1 line
11:13
<matttttt>
oh? i was just following the opensuse guide for 'enabling nxagent for slow links' which just said to change my LDM_COMMAND to /usr/bin/nxagent-gnome or whatever, but that didn't seem to make a big difference.
11:13
maybe i was missing some piece
11:14
yeah, the bootup is going to suck, but if i stick with ltsp i think i can convince them to just put a junky pxeboot server at each site, hardware requirements are silly low for that.
11:14
i found out i'm onlypulling 45-49m of my 150m image from power on to ldm screen, but even that takes like 5+ minutes over a t1
11:14
<Gadi>
seems like what opensuse is trying to do is use ldm+nxagent
11:15
not sure how that compares to just running nxclient
11:15
<matttttt>
gadi, yeah. i wasn't impressed with the results, i did see the nxagent splash
11:15
i'm doing nxclient from a live cd right now, and running nxserver on my server, hauls proverbial ass.
11:15
<ogra>
i dont think we support LDM_COMMAND at all upstream
11:15
<matttttt>
i even rate limited my t1 to half speed and it's still zippy
11:15
<Gadi>
right
11:16
<ogra>
so that must be a suse hack
11:16
<Gadi>
I would just write an nxclient screen script
11:16
<ogra>
right
11:16
didnt you once have one ;)
11:16
you should probably forward port it
11:16
<Gadi>
thanks, boss
11:16
:)
11:16
<ogra>
*g*
11:17
<vmlintu>
ldm+nxagent doesn't compress data, it does only round-trip suppression
11:17
<matttttt>
vmlintu: ah, that'd explain my barely perceptible improvement
11:17
vs. full on nxclient
11:17
<vmlintu>
It helps the most if you use ssh connection with slow clients
11:17
<ogra>
ldm+nxagent really sounds like an insane hack vs a proper screen.d script
11:18
why involve ldm at all
11:18
<matttttt>
perhaps the login screen is prettier?
11:18
<vmlintu>
I've seen impressive performance boosts for firefox and friends with ldm+nxagent
11:19
But if you have fast network and fast thin clients, there's no improvement
11:19
<matttttt>
vmlintu, not sure if you read above but i just provisioned a test "t1" link between two netopia cpes and put a client on one end and my server on the other, no nxagent = barely usable with one client connected. i'm talking menus taking forever to popup, etc. ldm+nxagent had a barely perceptible improvement, still unusable on this link
11:20
<vmlintu>
ldm+nxagent doesn't need any changes to the chroot
11:20
<matttttt>
booted a livecd with nxclient, connected to the nxserver on my server and blam, super fast.
11:20
almost seems local
11:20
cut the t1 in half, same results.
11:20
<vmlintu>
t1 is like 2mbps?
11:20
<matttttt>
1.54
11:21
<vmlintu>
never see those over here
11:21
<matttttt>
the defacto lease line standard in the usa
11:21
sadly people still use them :(
11:21
so slow
11:21
<vmlintu>
I wouldn't use ldm+nxagent with anything slower than 100mbps
11:21
<alkisg>
Is that full-duplex?
11:21
I.e. 1.5 upload + 1.5 download?
11:22
<matttttt>
yes
11:22
well if i can figure out how to boot opensuse ltsp into nxclient instead of ldm i'll be set it seems. ah, more work
11:23coordinador has quit IRC
11:24
<vmlintu>
basically ldm+nxagent doesn't reduce bandwidth requirements at all. I've been running it at some production sites for a year and it looks like slow thin clients with ssh encryption get the biggest boost from it.
11:24
It takes away the sluggish feeling when the cpu cannot encrypt ssh data fast enough for all x roundtrips

<matttttt>
ah
11:29
so can someone point me in the right direction for booting opensuse ltsp into nxclient instead of ldm? what should i go read? i know nothing about screen scripts
11:29
i'm very exciting about this find :) i was beginning to think it was hopeless to have any clients at these t1 sites.
11:30
<ogra>
basically take a look at the scripts in the ltsp screen.d directory
11:30
for opensuse specifics rather go to #kiwi-ltsp
11:31
<Gadi>
matttttt: http://www.ltsp.org/~sbalneav/LTSPManual.html#screen-scripts
11:31
<ogra>
regarding screen.d its likely easiest to copy the rdesktop script as a base and modify it
11:32
<Gadi>
matttttt: nxclient stores config files in: ~/.nx/config/$sessionName.nxs
11:33
matttttt: you can start nxclient with a particular config with: nxclient --session /path/to/file.nxs
11:33
the rest is left as an excercise for the reader

how can i change keyboard layout in terminals? (directly working on server, it worked fine)
11:36
<ogra>
did you set the proper values in lts.conf ?
11:37
<coordinador>
i have ltsp4.2 and i think values are ok, since it happened suddenly
11:38
just in case i added XKBLAYOUT=es in /tftpboot/ltsp/i386/lts.conf
11:38
but nothing happen
11:39
it happened after an ubuntu 9.04 update yesterday
11:39
<Gadi>
coordinador: ltsp 4.2 has config in: /opt/ltsp/i386/etc/lts.conf
11:39
<coordinador>
the system asked to reboot and when i back , that happened
11:39
Gadi, i have ltsp4.2 and ltsp5 at the same time, thats why i have it in another dir
11:40
<Gadi>
well, it won't have an effect on ltsp 4.2 in that directory
11:41
in any event, get a shell on the thin client and check the layout in /etc/X11/xorg.conf
11:41
<devilbues>
hi, anyone managed to get rdesktop using local devices with windows 2008? I keep getting this 0x8007048f error

er, 0.5.13
11:43

Gadi, i havent /etc/X11/xorg.conf in shell terminal

gadi: ubuntu 9.04 server, 0.5.10

coordinador: are you on a 4.2 client with SCREEN_01 = startx, SCREEN_02 = shell ?
11:43
<coordinador>
yes gadi
11:43
exactly that way
11:44
<Gadi>
coordinador: ah, look in /tmp or /var
11:44
I think the Xorg.conf is there in 4.2 somewhere
11:44
<coordinador>
ok
11:44
ill check
11:45
<Gadi>
devilbues: are you following: https://help.ubuntu.com/community/UbuntuLTSP/RdesktopLocaldev
11:45
<coordinador>
tmp/X11R6Config.1 is the only file that looks like xorg.conf
11:45
<Gadi>
thats the one
11:45
<coordinador>
how can i configure permanently?
11:45
<Gadi>
well, first checck if the layout is correct
11:46
if it is not correct, then you are not setting lts.conf properly or it is in the wrongplace
11:46
you can look at /etc/lts.conf from the shell to check your config
11:47
<devilbues>
Gadi: yes, i can see the device, and it works correctly with windows 2003, but in windows 2008 gives-me this error when I copy something: "error 0x8007048f: the device is not connected"
11:48
<Gadi>
hmm... I have not seen that
11:48
<coordinador>
i checked the correct lts.conf for ltsp4.2, it hasnt specified the keyboard layout, ill put XKBLAYOUT=es, it worked for 4.2 right?
11:49
<devilbues>
Gadi: do you use it with windows 2008?

best to note down on a piece of paper that your config files for ltsp4 and 5 are in different places ;)
11:52
<coordinador>
i dont know why i must to configure manually the keyboard layout again, it happened suddenly...
11:53
yes, ill do
11:53
<Gadi>
were you doing something silly like bind-mounting the config files so you would only have to edit one and then on reboot not have the mount happen automatically?
11:53
<ogra>
so yu remember it in a few weeks if you want to change the next thing :)
11:55
<devilbues>
Gadi: what distro are you using
11:55
<Gadi>
same as yours
11:55
devilbues: though, you might want to see if ltspfs 0.5.13 is packaged anywhere
11:56
we fixed a few things for local ltspfs
11:56
I wonder if stgraber has it in his ppa
11:56
<coordinador>
haah..This layout problem and a problem with gnome theme, both things happened suddenly, but the gnome theme was fixed unchecking a keyboard plugin entry of gnome-settings-daemon, with gconf-editor, maybe that is a bug, ill report it
11:56
<ogra>
stgraber might have it in PPA

i think my sound problem with ltsp is related to intel sound chip on the client
12:09
<Lns>
000000########00000###
12:10
<Ahmuck>
in previous versions of my distro, it appears intel sound was dropped from the kernel
12:10
<Gadi>
really?
12:10
<Ahmuck>
i do get sound briefly in ubuntu 9.04, but it stops
12:10
<ogra>
thats a bad distro
12:10
<Gadi>
what driver?
12:10
<Ahmuck>
should i assume that the kernel module for intel sound is not getting loaded properly?
12:10* ogra guesses inter hda
12:11
<ogra>
*intel
12:11

never assume
12:11
<Ahmuck>
yes, hda_intel
12:11
<Gadi>
get a shell on the client
12:11
<Ahmuck>
it shows intel 82801BA-ich2
12:11
k, how do i do that?
12:12

well, you could set: SCREEN_07=ldm SCREEN_08=shell in lts.conf

the server need not have a video card or sound card in LTSP
12:56
<Lns>
^^^ =) love that
12:56
<maginot>
I'm having some issues with keyboard so i make a xmodmap file and I'm loading it per user but on the ldm login screen I want to make use of this xmodmap setting.... anyidea on how to do that??
12:56
<Ahmuck>
on sdl apps, is it possible that ltsp is not using the correct video configuration for the client?
12:56
<Gadi>
video works like this: application --> xserver on thin client (or application --> SSH Xproxy --> Xserver on thin client)
12:57
sound is: application --> alsa on server --> fake pulseaudio soundcard --> pulseaudio daemon on thin client --> alsa driver on thin client --> thin client soundcard

Gadi: do you know of any virtual audio card drivers for windows, so you don't have to install a physical card to get it in rdesktop?
12:58
<Gadi>
maginot: you can create an I* script in /opt/ltsp/i386/usr/share/ldm/rc.d/
12:58
<Lns>
(install physical card in server that is)
12:59
<Gadi>
Lns: RDP also uses a virtual soundcard - the RDP Virtual Sound Driver
12:59
thats what Windows uses by default
12:59
in RDP sessions

Gadi: really? so you don't need a sound card in the windows server?
13:00
<Gadi>
nope
13:00
<maginot>
Gadi, I* script? If I put Xmodmap inside /etc/X11 on chroot isn't going to work ?
13:00
<Lns>
heh...maybe I *won't* use those subcontractors for windows terminal server help when i need it then ;) they were dead set on saying you needed it
13:00
<Gadi>
maginot: I didn't say /etc/X11, did I?
13:00
<Lns>
i had to go out and install 7 of em
13:00
<Gadi>
take a look in that directory
13:01
<Ahmuck>
another issue, which i need to address later is that closing firefox sometimes leaves a hanging process and upon loging back in, or rebooting, firefox won't open cause it think's it's already open
13:01
<Gadi>
Lns: I have definitely had w2k3 servers with no sound card and sound through rdp
13:02
<Ahmuck>
kewl -- a new version is avaialbe, rebooting in 10 sec
13:02
<maginot>
Gadi, no, but I'm going in a diferent line of thinking ;P... I'have already looked inside rc.d of ldm dir, there are a bunch of scripts, so by this way what should I do, make an script using xmodmap -e command lines ? (makes sense)
13:02
<Gadi>
right -
13:02
if you preface with "I" it runs on ldm initialization
13:03
those scripts are sourced
13:03
<maginot>
Gadi, like Imykbsetting.sh ?
13:03
<Gadi>
no, look at the format
13:03
it is: I<number>-<name>
13:03
so it gets sourced in order
13:04
<maginot>
Hmm sure, I was just guessing cause I'm not in the server at this moment, now I understood.. very simple in fact
13:04

yeah - we made the framework for just such an emergency :)

hmm, no, istn what i thought it was
14:03

it would make debugging pulseaudio in our environment much easier
14:04
since you can tell someone: type: pulseaudio -F /usr/share/ltsp/default.pa -n
14:04

yes, but i would like a proper configfile option instead of a pulse script
14:04vagrantc has quit IRC
14:04

whats the diff?
14:05

default.pa is typically a set of commands you would usually give to pulse on the pulse interpreter
14:05
its not like daemon.conf or client.conf
14:05
<Gadi>
ah - and why do we not use daemon.conf?
14:06
<ogra>
becaue its a conffile
14:06
ucf wuld kick in if you upgade the package and we modified it
14:06
asking the user confusing questions
14:06
<Gadi>
ah - then why do we not use a default.pa script?
14:06
:)
14:07

because it wont have the standard config options but rather script command

14:50
<alkisg>
Yup?
14:51
<Gadi>
got a question regarding your dhcp proxy stuff
14:51
<alkisg>
Shoot
14:51
(but it isn't mine, it's the dnsmasq developer's :))
14:51
<Gadi>
let's say you had a dhcp server behind the proxy that ALSO hands out tftp filename, etc
14:51
does it ignore the server and replace with its own?
14:52
<alkisg>
"behind"? Both of them are usually on the same subnet, it's not a "distant" proxy server...
14:52
<Gadi>
same subnet?
14:53
<alkisg>
Yes, e.g. I have a simple local network, with a router acting as a dhcp server, and the ltsp server with a single NIC acting as a "proxy dhcp" server
14:53
<Gadi>
I had envisioned: enterprise-wide DHCP server -> lots of subnets -> one subnet has a proxy that fills in filename info
14:54
<alkisg>
Let me find the package name that I think you need...
14:54
<Gadi>
so, thin client requests from proxy -> proxy gets IP info from server and adds filename info
14:54
<alkisg>
I think that you need dhcp-relay
14:55
<Gadi>
so, why can't dhcp relay do what dnsmasq does?
14:55
<alkisg>
Dhcp relay = use a single dhcp server on different subnets
14:55
Dhcp proxy = fill in some additional info if you don't have access to the dhcp server
14:56
(afaik)
14:56
<Gadi>
ah, but the proxy must also get the IP from the server and relay it
14:56
it is just adding to it
14:56
<alkisg>
No, the client actually gets two offers
14:56
<Gadi>
as it relays
14:56
<alkisg>
The first one is from the "normal" dhcp server, and contains the IP lease,
14:57pem725 has joined #ltsp
14:57
<alkisg>
and the second one comes from the proxydhcp, and only contains the filename, root path etc
14:57
<Gadi>
shouldn't the client only accept one?
14:57
<alkisg>
No, it's part of the protocol
14:57
The second offer isn't a normal offer, it doesn't contain an IP
14:57
It's a special "proxy dhcp offer" which only contains the filename etc
14:57
<Gadi>
interesting
14:58
and, I take it, there is no: dhcp-proxy package
14:58
<alkisg>
No, but dnsmasq can act as dhcp-proxy *only*
14:58
i.e. no dns, no tftp, no normal dhcp...
14:58
<Gadi>
it would be interesting if you could do dhcp-relay + dhcp-proxy
14:59
<alkisg>
That can be done, but I don't see the reason why...?
14:59
<Gadi>
lets say you don't have control over the enterprise dhcp server
14:59
<alkisg>
Ah, sure, that's the main reason to use a proxy dhcp
15:00
Cheap routers (=non configurable), or dhcp servers that we don't have access to
15:00
<Gadi>
ah, right - and I guess if it were not the same subnet, you would have to change the dhcp server anyway
15:00
nevermind
15:00
I got it
15:00D`aZ is now known as DaZ
15:01
<Gadi>
thx, alkisg
15:01
<alkisg>
That's where the dhcp-relay comes in, to enable a dhcp server to serve many subnets
15:01

I'm looking for a little troubleshooting help for LTSP on Ubuntu 9.04. Any gurus in here?
15:10
<Gadi>
Justin1: we're on the edge of our seats :)
15:10
<Justin1>
I have an issue with clients randomly logging out. Alas, my googlefu has failed.
15:11
<Gadi>
are they running the random-logout script?
15:12
<Justin1>
That is a good question. I have never heard of such a thing. The last time I used LTSP was several years ago, and a great deal has changed since then.
15:12
<Gadi>
heh - im joking
15:12
so, is there anything in common with when they log out?
15:12
<Justin1>
I should hope. The first thing that came to mind is when we would ask new guys to change the spark plugs on the diesel engines.
15:13
<Gadi>
nice
15:13
well, first off, does it kick them out to a login screen?
15:13
or do they freeze?
15:13
<Justin1>
Users are just browsing the net. Firefox is the only app running.
15:13
Yes, to a login screen.
15:13
<Gadi>
sounds like ye olde pixmap issue
15:14
<Justin1>
Ah, yes. Ye olde pixmap.
15:14
<Gadi>
is it when they go to a site with mucho large graphics?
15:14
<Justin1>
So, uh, what is that?
15:14
Often during searches.
15:14
Google searches, that is.
15:15
<Gadi>
now, thats odd
15:15
<Justin1>
Likely they are clicking on links. All I hear is, "I was just doing a search!"
15:15
<Gadi>
ah
15:15
how much RAM in the clients?
15:15
<Justin1>
128M, iirc
15:15
<Gadi>
have you modified the lts.conf at all?
15:15
<Justin1>
No.
15:16
<Gadi>
well, you can try enabling NBD_SWAP and seeing if that helps mitigate the problem
15:16
also, there is....
15:16
whats the param...
15:17

15:17

Gadi: would changing allocated video ram in the clients' BIOS help?
15:17CAN-o-SPAM has quit IRC
15:17
<Gadi>
X_RAMPERC = 90
15:17
or so
15:17
video ram in the clients may help to
15:17
*too
15:18
<Justin1>
Hmm. Good suggestions.
15:18
<Gadi>
this is all under the presumption that it is a memory issue
15:18
Justin1: sorry - im being vague
15:18
NBD_SWAP = True
15:18
would enable some network swap space for the clients
15:18
so, if they run out of memory they can swap to the server hard drive
15:19
not ideal, but can prevent logouts a bit
15:19
<Justin1>
That would make sense. When I played with LTSP in days of yore, the only locally running thing was X.
15:19
So memory wasn't much of an issue.
15:19
<Gadi>
yeah, the issue here is that programs like firefox load images into the Xserver memory
15:19
mostly without regard
15:19
<Lns>
Justin1: that's still the case (unless you use localapps)..but yeah, what gadi said ^^ too
15:19
<Gadi>
so, even though you think ff is just using the server's memory.... surprise!
15:20
the ff folks don't use thin clients much
15:20
:)
15:20* Lns remembers chatter regarding an X module that might redirect pixmap calls to the server
15:20
<Justin1>
That actually makes sense. Then again, I was trying to justify the random_logout_script in my head too.
15:20
<Gadi>
anyhow, the X_RAMPERC = 90
15:21
would tell the client to set a ulimit of 90% on the memory for the Xserver
15:21
which is supposed to make Xclients like firefox die before the entire session dies

I am not at the site with the server right now, and I haven't poked a hole in the firewall to use ssh. I am assuming that XRAMPERC is also in lts.conf?
15:22
<Ahmuck>
is there a way to test latency to see if that is what is causing pulse to die?
15:22
how does one allocate more video memory on the client?
15:23
yes
15:23
<Justin1>
I'm glad Ahmuck asked that. I was feeling positively amateurish.
15:24* Ahmuck is an amature
15:25

is that the way it's spelled?

That would be a-mature, like amoral. It means you're young at heart :-)
15:25
<Gadi>
one question at a time
15:26
Justin1: yes (to lts.conf)
15:26
Ahmuck: in the BIOS (to allocating more vid memory - BIOS results may vary)

Since we are on the cause of memory usage in the client, would color depth also affect this?
15:27
<Gadi>
sure
15:28
goes to number of bytes
15:28
:)
15:28
<Justin1>
I'll reduce that as well. Makes sense.

andrey___: do they not mount or do they appear on all displays?

15:30
i thought you spelled it wrong
15:30
until i google spell checked it and was kinda shocked
15:30
<andrey___>
they do not mount
15:31
<Justin1>
English: one screwed up language.
15:32
<andrey___>
not mount due to authentication in Active Directory ... Active Directory does not belong to the group fuse.
15:32
<Gadi>
andrey___: several ways to skin this....
15:32
cleanest would be to use pam_group
15:32
<andrey___>
not mount due to authentication in Active Directory ... Active Directory user does not belong to the group fuse.
15:32
ok
15:32
<Gadi>
andrey___: have you used pam_group before?
15:32
<andrey___>
no
15:33
:)
15:33
<Gadi>
ok - it should be installed by default
15:33
modify: /etc/security/group.conf
15:34
<andrey___>
yes
15:34
<Gadi>
lots of examples in there for the syntax
15:34
<andrey___>
thanks
15:35
<Gadi>
pam_group is session-based group assignments
15:35
all of your other alternatives are a bit messier
15:35
:)
15:36
<andrey___>
ok

you need to change example to default
15:42

I did

oh sorry

<Gadi>
confused by the 2 pastes
15:43
<bieb>
ohh the first paste was a refresh of the browser by accident
15:43
<Gadi>
so, with this lts.conf it fails to boot, but with no lts.conf it boots?
15:43
<bieb>
correct

15:45
<Gadi>
try having *just* those three lines
15:45
remove all the other comments and cruft
15:45
<bieb>
I know.. its not like I have a whole bunch of info in there
15:45
ok.. I will ...
15:45
do i need to run ltsp-update-image??
15:45
<Gadi>
nope
15:46
<bieb>
is it possible that is what caused the issue?
15:46
<alkisg>
bieb: is that the ltsp 4.2 installation, or the ltsp 5 one?
15:46
<Gadi>
not unless you edited something you shouldn't have in /opt/ltsp/i386
15:46
<bieb>
ltsp5
15:46
on ubuntu9.04
15:47
<alkisg>
OK... what do you have in /var/lib/tftpboot/ltsp/i386/lts.conf ?
15:47
<bieb>
I can remove the lts.conf in /opt/ltsp/i386 also
15:47
alkisg: http://pastebot.ltsp.org/463
15:47
<alkisg>
Ah, ok I thought that was the /opt/ltsp/i386 one...
15:48
<bieb>

<bieb>
I wanted to include the location of the file, which shows at the bottom of the screen
15:55
<Gadi>
so, did you reboot the client?
15:56
<bieb>
getting ready to in a second...
15:56
<Gadi>
ah, ok
15:59
<bieb>
same issue
16:00
<Gadi>
bieb: can you try again with no lts.conf?
16:00
<bieb>
yep.. back in a few
16:00* Gadi worries that bieb broke something in his chroot
16:01
<Gadi>
nothing worse than a broken chroot
16:01
unless, maybe, a chroot canal

is there anyway that when you do a ltsp-build-client that you dont have to do it off the net?
17:10
<alkisg>
atomic007za: you can use --mount-cdrom, if you have an appropriate cd-rom (e.g. the ubuntu alternate cd)

If have updated the system, is this still a good idea?
17:13
if so would it be: ltsp-build-client --mount-cdrom
17:14
<alkisg>
No, the sources would need to include the cd rom
17:15
ltsp-build-client --extra-help lists all the options

sound familiar?
18:28staffencasa has quit IRC

<Gadi>
_aegis_: that usually means you either have more than one NIC in your client or you lack the proper network driver in the initramfs
18:33Sarten-X has quit IRC
18:34Sarten-X has joined #ltsp
18:34
<_aegis_>
one nic, and it properly loads the network driver a few lines up
18:35
or seems to
18:35
http://aegis.eat-peet.net/img/diskless.png
18:37pmatulis has joined #ltsp
18:37
<Gadi>
seems the network driver is loaded, but ipconfig is failing
18:38
try editing /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
18:38
and adding: break=mount
18:38
to the kernel comman line
18:38
that should boot the client to an initramfs> prompt
18:38
from there, you can try typing: ipconfig -d eth0
18:39
and see if it works

hey friends
18:41
<_aegis_>
and the network works
18:44
<Gadi>
_aegis_: weird... I think someone else had this issue
18:44
<_aegis_>
I know a ton of people have had a similar issue
18:44
but none of the solutions worked for me
18:45
<Gadi>
I think most cheat and add IPAPPEND 3 to their pxelinux.fg/default file
18:45
<_aegis_>
which does?
18:45
<Gadi>
if you add a second line like that to that file,
18:45
it uses the IP info it gets from the PXE request as the IP for the OS
18:45
without requesting a second time
18:45
<_aegis_>
which is what's supposed to happen anyway...
18:45
<Gadi>
you can try it
18:45
<_aegis_>
because it mounts nfs
18:46
<Gadi>
no, normally, the initramfs runs ipconfig to get the IP
18:46
<_aegis_>
oh okay
18:46
hmm
18:46
<Gadi>
before it mounts nfs
18:46
<_aegis_>
works for me if it works :)
18:46
<Gadi>
hehe
18:46
cheater
18:46
:)
18:46
I gotta run
18:46
good luck!
18:46
