00:25* vagrantc uploads ltsp 5.1.98-1 to debian unstable...
00:26
<vagrantc>
and i already have a commit in my bzr branch that didn't make it into the upload... :)
00:52
i keep meaning to update ltsp-docs in debian, and never get around to it. i'd best handle that before the freeze.

ogra, stgraber, would you care to sponsor a MIR for libsdl1.2debian-pulseaudio? It would be the first step in solving LP #203158 (the second one being, changing the seeds)

Hello. Is there a way to reload /etc/lts.conf on a client w/o rebooting?
06:34
<alkisg>
Distro/version?
06:34
<vlt>
Ubuntu 8.04 LTS
06:35
<alkisg>
That would be /var/lib/tftpboot/ltsp/i386/lts.conf, then, and no, it's not easy to reload it without rebooting the client.
06:35
<vlt>
I edited the client's (copy of) lts.conf manually and restarted X but it seems that the values were not taken from the changed file.
06:37
I want to test some X settings w/o rebooting the client every time ...
06:37
<alkisg>
Why don't you try X -config <file> then?
06:39
I guess you could also insert an eval /usr/bin/getltscfg -a in a startup script...

hey all
08:04
anyone in here familiar with cluster? I am trying to figure out how to apply a hardware profile to a node...

shawnp0wers: did you figure out how to apply hardware profiles in cluster?
08:29Ahmuck-Jr has joined #ltsp
08:29
<shawnp0wers>
Figure out, yes -- utilize, no.
08:30
<_UsUrPeR_>
I got the node part (thanks :) but can't figure out how to apply hardware profiles to nodes/MAC addresses...
08:30
<shawnp0wers>
Basically, you pick a specific bit of hardware (like CPU speed or something), and make a hardware profile based on that
08:30
<_UsUrPeR_>
huh
08:30
<shawnp0wers>
I don't have cluster installed anymore, but
08:30
if you look at a specific computer
08:30
and it tells you all the nitty gritty about it
08:31
like, cpu speed, ram size, etc
08:31
<_UsUrPeR_>
ahh
08:31
<shawnp0wers>
and you make a hardware profile based on one of those strings
08:31
<_UsUrPeR_>
brb
08:31
<shawnp0wers>
it should apply that hardware profile to the computers in the list
08:31
I assume it supercedes other groupings
08:31
(like node listings)
08:31
to separate by MAC addres, you'd create a new node
08:31
and assign settings to that node
08:32
hardwaer profiles are only if you want to specify a certain type of hardware, or something "below" a certain Ghz or something
08:32prpplague has left #ltsp
08:32
<shawnp0wers>
to make groups of compuers, you'll still want to make a new node

<_UsUrPeR_>
shawnp0wers: ahh.
08:44
<shawnp0wers>
Does that help?
08:45
<_UsUrPeR_>
shawnp0wers: I'll check it out. I'm looking through options right now
08:45
<shawnp0wers>
One of my biggest beefs was that many lts.conf options were missing
08:45
like shutting off sound for specific groups
08:45
that sorta thing
08:45
<_UsUrPeR_>
shawnp0wers: Did my hints about adding options via psql changes help at all?
08:46
<shawnp0wers>
In theory yes, but I was too uncomfortable with the "alpha" feel of Cluster to fiddle too much.
08:46
Not a shot, but I just felt too out of control
08:47
if I can't figure out *why* something is working, it worries me to depend on it
08:47
if that makes any sense
08:47
I'm just going to manually load balance between LTSP5 servers, using a common symlinked lts.conf file
08:47
the fact that lts.conf no longer contains the server IP address is *awesome*
08:49
<_UsUrPeR_>
hey, according to 2 Fast 2 Furious, "If you're not out of control, you're not in control."
08:50
<shawnp0wers>
Yeah, but at least then I have a clutch, gas, and brake to soothe me. :)
08:50
<_UsUrPeR_>
err wait, that was fast and the furious: tokyo drift :)
08:55
anyway, it's alright. I live my life a quarter mile at a time.

Hello edlima
10:44
<edlima>
Hi!!! Do you know if exist a room about sane on ltsp?
10:45
<sbalneav>
This would be it.
10:46alkisg has joined #ltsp
10:47
<edlima>
Sorry! someone called me in another room!
10:47
<sbalneav>
alkisg: Morning, thanks for adding a use case
10:47
<ball>
What is sane?
10:47
<alkisg>
Hi sbalneav
10:47
<edlima>
Hi sbalneav! I just want to know about scanners in ltsp
10:48
<sbalneav>
ball: Scanner Access Now Easy, i.e. scanning for ltsp thin clients.
10:48
edlima: What do you want to know?
10:48
<edlima>
ball, sane is a project created to run scanner on Linux
10:49
<ball>
Ah okay. I thought perhaps the name had been recycled.
10:50
Is it possible to attach a scanner to the USB port of an ltsp terminal and have it visible to software running on the application server?
10:50
(where the desktop is running)?
10:50
<edlima>
sbalneav, I have one scanner connected on my thinclient and I want to make this scanner work in this station
10:51
<Gadi>
edlima: SCANNER=True
10:51
in lts.conf
10:52cliebow has quit IRC
10:52cliebow has joined #ltsp
10:52
<edlima>
ball, is it! The scanner is connected in a terminal via usb, I installed the sane an change the lts.conf file, but nothing
10:53
Gabi, I put it in lts.conf, but nothing yet
10:53cliebow has quit IRC
10:53cliebow has joined #ltsp

<edlima>
Sorry about my english, I don't know very well
10:54
<Gadi>
edlima: grep -i SCANNER /opt/ltsp/i386/etc/init.d/ltsp-client-setup
10:54
or: grep -i scanner /opt/ltsp/i386/usr/share/ltsp/ltsp-init-common
10:55
if both of those come up empty, then you have too old a version of ltsp
10:56
<edlima>
Gabi, I have the first one, but when I type this command nothing is showed to me
10:56
<ball>
...and that scanner only attaches to the desktop of the user who's logged in at that terminal?
10:57
<Gadi>
ball: yeah, but any user should be able to see it (i believe)
10:57
it is simply a network scanner
10:57
<ball>
Hmm...
10:57
<Gadi>
edlima: if it returns nothing, then you have too old a version of ltsp
10:58
<edlima>
ball, can be, can be... My first idea was the scanner plugged in this desktop and all the people access this
10:58
Gabi...hummm
10:58
<Gadi>
edlima: what distro are you on?
10:59
<edlima>
I'm using Ubuntu 8.04 + LTSP 5
10:59
Ubuntu LTS 8.04 ins the name
10:59
<Gadi>
yeah - much has changed since hardy
10:59
<edlima>
hardy heron...rsrsrs
11:00
<Gadi>
you can try building a karmic chroot
11:01
sudo ltsp-build-client --dist karmic
11:01
or some such
11:01
<edlima>
well, When i plug the scanner on a terminal and type in TC lsusb, is showed to me the scanner map
11:01
Gabi. Is it possible?
11:01
<Gadi>
or look at the patch in launchpad that added scanner support
11:02
edlima: what have you got to lose?
11:02GGD has joined #ltsp

hello GGD
11:05
<edlima>
The server whos have this system is too important here! I have to take much care! rsrsrs... but I will try to do it! But in the night, when the people go home!
11:05
Can I build a karmic client in hardy heron server?
11:06
I didn't know!
11:08* ball struggles with Sun Ray Vs. ltsp
11:09
<edlima>
Gabi, I typed in lts.conf one line with "XINETD_SERVICES = saned", is it necessary?
11:11
<Gadi>
edlima: no - that was ltsp4
11:16
<edlima>
hmmm...ok... I thought that was more easy, but can be my limitation...rsrsrs
11:17
Ok, after I put here if I have success or no!
11:17
Thank U so much Gabi!
11:18
Bye ball
11:18
See U!

I have a host with an Intel e1000 NIC, I'm trying to PXE-boot it, but it stops at the "TFTP..." stage.
11:48
Server is 192.168.1.4, client gets 192.168.1.5. tcpdump: 18:27:35.109357 IP 192.168.1.5.2071 > 192.168.1.4.tftp: 30 RRQ "grub2pxe" octet blksize 1456

<jelly-bean>
we have 3 dif users logged in as dif ubuntu users
11:50
but they are all browsing the same intranet site in firefox
11:50
and it appears to be sharing some session data
11:51
because when one user logs in they like all become the same person
11:51
is this any kind of known issue
11:51
<sbalneav>
rhodan_: What tftp server are you using?
11:51
<rhodan_>
tftp-hpa
11:52
<sbalneav>
rhodan_: what's with all the mtftp stuff then?
11:52
<rhodan_>
Don't I need it?
11:52
<sbalneav>
jelly-bean: could be the web site itself
11:52
<rhodan_>
I must admit I copied it from a HowTo...
11:52
Which parts can I remove?
11:53
<sbalneav>
jelly-bean: if it's only tracking users by IP, all users are coming from the same server with LTSP
11:53
<Gadi>
rhodan_: you define the filename as part of a class but dont use the class anywhere
11:53
<sbalneav>
rhodan_: Use/modify the dhcpd.conf file that normally ships with ltsp
11:53
should be in /etc/ltsp/dhcpd.conf
11:54
<rhodan_>
sbalneav: Can you nopaste it? I don't have LTSP. I want to make a diskless client with NFS-/.
11:57
<sbalneav>
http://ltsp.pastebin.com/m7545dd1c
11:57
If you don't have ltsp, you're going to have to modify that.
12:00
<alkisg>
rhodan_: also, grubpxe isn't really mature to be used in pxe booting. Better use pxelinux for that.
12:00
<sbalneav>
LTSP also supports the chroot via NFS
12:00
<rhodan_>
Grub2 is pretty good.
12:00gfarras has quit IRC
12:00
<alkisg>
rhodan_: yeah it's good, but it doesn't support pxe properly yet
12:01
Have you actually booted anything with grubpxe?
12:01
<rhodan_>
grub*2*pxe
12:01
<alkisg>
Right
12:02
I sent a query to the grub-devel list about some problems I was having with grub2 and pxe, and the developer replied to me a week ago and said I should wait for him to include some modifications
12:02
So I'm waiting... I guess in a couple of years it'll be mature enough :)
12:03
<sbalneav>
rhodan_: Besides, if you're NOT using ltsp, and you ARE trying to use grub to pxe boot, wouldn't #grub be better?
12:09
<rhodan_>
sbalneav: I'm not having a GRUB problem ATM.
12:10
And for TFTP/DHCP problems, this is a better place to ask.
12:12ball has left #ltsp
12:15etyack has joined #ltsp
12:16
<alkisg>
rhodan_: so for your other hosts, you're able to boot them with grub2pxe and then with nfs?
12:17
...and the problem is just this one host?
12:17
<rhodan_>
I have only this host, for testing.
12:17
If I get the whole thing to work, I'll deploy it.
12:17
<alkisg>
(07:50:12 μμ) rhodan_: TFTP is up and running, I can fetch grub2pxe from other hosts without any problems.
12:17
What do you mean by that? ^^^
12:17
<rhodan_>
alkisg: yes, tftp 192.168.1.4
12:17
tftp> get grub2pxe
12:18
tftp> quit
12:18
<alkisg>
Ah, not by booting them... got it
12:18
<Gadi>
rhodan_: the dhcpd.conf file you posted never told the clients the filename to get
12:18
it was only defined within a class
12:18
<rhodan_>
But they requested it according to txpdump...
12:18
*tcpdump
12:18
<Gadi>
hmm..
12:19
do you have next-server in there?
12:19
<alkisg>
Gadi: they wouldn't accept the dhcp address then
12:19
Ah it's gpxe, they wuld
12:19
would
12:19
<Gadi>
I guess it is matching the client to the class
12:19
nevermind

rhodan_: while trying grub***2***pxe, I also had the same problem with it just hanging
12:21
<rhodan_>
Really? I'll try syslinux.
12:21
<alkisg>
After 1-2 days of tried, I got it to not hang on 1 of the 3 test-pcs
12:21
<Gadi>
is grub2pxe in the tftpboot root?
12:21
<alkisg>
But it just got me to the rescue> prompt
12:21
Then I mailed the list. That was in the summer. One week ago, I got the reply that it's not ready yet.
12:22
<Gadi>
ah, you fetched it with tftp
12:22
rhodan_: you can make tftp more verbose, restart inetd, and check syslog
12:23
<rhodan_>
alkisg: Oh, but for me, it hangs at "TFTP."
12:24
TFTP..
12:24
TFTP...
12:24
<alkisg>
Yes, I had that on my first try
12:24
But it might also be a different problem
12:24
What I'm saying is that it'd be easier to get it going with pxelinux, and if you want, try grub2pxe later...
12:25
(easier to debug, that is...)
12:26
How did you call grub-mkimage? with what parameters?
12:27
<rhodan_>
These. http://grub.enbug.org/PXEBOOT
12:27
<alkisg>
Yeah that's what I tried too, they're wrong
12:27
gpxe tries to load grub as a multiboot image, so it doesn't work
12:28
Anyway if you ever get it going with grub2pxe, do tell me how you did it...
12:36highvoltage has quit IRC
12:36
<rhodan_>
Same results with pxelinux.0
12:39
<alkisg>
What gpxe version are you using?
12:39
I think they had some problems with e1000 until recently...

I use the built-in PXE.

Do put a next-server directive, maybe it needs it.
12:46hersonls has quit IRC

But it already requests the PXE image at the TFTP server, as tcpdump says.

"Bouncing the TFTP server fixed it. I should have just bounced the service but it was a "nuke from orbit" type day and the server is not a production box." -what's "bouncing"?

So it's still the orignal?

What server's this on?
13:03
<rhodan_>
192.168.1.4
13:03
Same as the DHCP server.
13:04
<sbalneav>
I mean, what kind of linux distro are you using?
13:04
<rhodan_>
Gentoo Linux.
13:05
<sbalneav>
Have you tried a different network card other than the E1000? It could be it's pxe implementation is broken.
13:05
Either that, or it could be a problem with gentoo's tftpd
13:05
Or, you have a smart switch that's blocking tftp traffic. We've seen that before.
13:07

What do I do now? :(
13:32
<alkisg>
rhodan: ask in #etherboot, they may have some hints for you. E.g. with my limited experience on this, I've seen pxe roms who failed to boot if root-path wasn't provided, even if nfs wasn't used as a boot method...
13:32
Otherwise, just use gpxe (etherboot)
13:32
<rhodan>
But how do I get the machines to boot etherboot when I am not allowed to modify the disk?
13:33
<alkisg>
disk? Are those windows machines?
13:34
You can use floppies/cds/usb sticks, but if they have hard disks, it'll be easier if you put "boot from network" as a boot option on the disk
13:35
<rhodan>
Then I could just use GRUB and don't use PXE at all, tight?
13:35
I mean "right"...
13:36
<alkisg>
grub *with* gpxe, right...
13:36
(or grub4dos if those are windows pcs and you don't want to use a different boot manager)
13:36
<rhodan>
So, would gpxe load GRUB or the other way around?
13:37
<alkisg>
The other way around
13:38
<rhodan>
And where would it load gpxe from?
13:38

we've noticed some monitors cant figure out how to display properly in ubuntu ltsp. if we switch the monitor, the resolution appears fine. but some monitors don't show the whole screen, or they do but it seems stretched and the fonts are not easy to read because they appear kind of smeared
14:12
is that just a display driver issue? or how to fix?
14:22
<Appiah>
you sure its a _ubuntu_ and/or _ltsp_ issue?
14:23
not a xorg and monitor issue?
14:25
<alkisg>
jelly-bean: about the floppy, make sure each user has its own primary group
14:26
<jelly-bean>
Appiah: no not sure
14:26
<alkisg>
jelly-bean: about the monitors, you'll need to provide more info (graphics card, what monitor, xorg.log etc)
14:26
<jelly-bean>
theres no errors
14:26
it just doesnt look right
14:26
and the same machine works fine when u switch monitors
14:26
so its def the monitor
14:26
<alkisg>
Xorg.log provides info about the available modes
14:26
<jelly-bean>
vs. xorg could be
14:27
i c
14:27
i can check that
14:27
<alkisg>
Based on the card, the driver and the monitor's edid
14:27
xrandr also can tell you the modes, but only the available ones
14:28

if you have a usb stick
14:28
put the same ubuntu version on that stick as your ltsp setup

boot it from usb and see if you have the same issue

Hey all - does anyone know of a "session timer" for things like limiting a user's session to, say, 1hr. a day (think of things like public internet terminals in libraries, etc.)
14:28

an example user has adm, dialout, fax, cdrom, tape, audio, dip, video, plugdev, fuse

how many do they really need? all they do is firefox and openoffice

your method's a little bit more elegant than mine.

what if i only want some users to be rdp
15:03
or can they be prompted to choose?
15:03

Some *users*? Not some pcs?
15:03
<jelly-bean>
i could setup dhcp rules per-mac-address to have custom boot images per user class
15:04
<alkisg>
lts.conf supports per-mac-address settings,
15:04
<jelly-bean>
right. its all because of user prefs that we are even considering M$ crap
15:04
<alkisg>
but you're talking about users, not pcs...
15:04
<jelly-bean>
they want office vs. openoffice and some other crap like quickbooks
15:04
yeah
15:04
we have 40 pcs acting as thin clients and they are all the same hardware
15:04
i want them to be able to sit down at any machine
15:04
<alkisg>
You can offer them both environments, i.e. both ldm & rdp
15:04
<jelly-bean>
and be able to choose
15:04
like via grub or some way
15:04
<alkisg>
And they can choose whatever they want with alt+ctrl+f7 / f8
15:05
<jelly-bean>
ya that sounds promising
15:05
<alkisg>
They can even use them simultaneously
15:05
<jelly-bean>
how do i set that up alkisg
15:05
<alkisg>
And of course, there's always the option to let them logon to gnome, and then rdp to windows from inside their gnome session...
15:05
<jelly-bean>
ya but nah thats too hard for them
15:05
<alkisg>
Why? just a shortcut on their desktop
15:05
<jelly-bean>
i know they're tards
15:06
<alkisg>
ok
15:06
<jelly-bean>
if they could do that we'd run it in virtual box

Read the link about lts.conf, get rdp working, and then ask again about using hem simultaneously

Hello,

<jelly-bean>
power on computer, login, u r in windows
15:33
not power on computer, login, click an icon, login again, manage a window within a window
15:33
and complain that u want it like it was
15:33
u'd be surprised man trust me
15:34
<Lns>
jelly-bean: no, trust me..i've been through all of this before =)
15:34
<wsuetholz>
I am running a "heavy" implementation of ltsp.. Basically Mythbuntu diskless front end configuration, and I am having some troubles getting Suspend and wake up to work
15:34
The suspend works.
15:34* Lns is beginning to put his own weight behind the fact that "computers aren't MEANT to be user-friendly..the user needs to LEARN how the computer works"
15:34
<wsuetholz>
But the machine locks up on wakeup
15:35
I don't even get the BIOS spash screen showing.
15:35
Suspend and wakeup works ok if no OS is loaded first.
15:37
<alkisg>
wsuetholz: is that ltsp specific? or is it a general linux problem?
15:40
<jelly-bean>
what do u need to have multiple users RDP into a windows box
15:40
we got windows vista ultimate
15:40
do we need server 2003 ?
15:41
<alkisg>
wsuetholz: https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume
15:41
<Lns>
jelly-bean: not sure myself about the vista rdp restrictions..server 2000+ usually has all that stuff built-in, you just need CALs for each user
15:41
I think 2 are built-in
15:43* alkisg thinks so too, for more than 2 you'd need windows server 200x with terminal services, and cal licenses
15:45
<Lns>
and terminal services license manager setup iirc
15:49* Gadi wonders how you wake up from suspend if suspend turns off your network card
15:50
<Lns>
Gadi: power button?
15:51jelly-bean has quit IRC
15:51
<alkisg>
keyboard?
15:51
<Gadi>
I mean, if your network card is off and thus you have no rootfs
15:52
getting everything restored might get tricky
15:57
<Lns>
aaaaaaaah
15:57
Gadi: there's no NBD "restore connection" type functionality eh?
16:00
<wsuetholz>
alkisg: I actually haven't tried it with a non diskless boot, Don't have a spare SATA HD to try with... Other people have reported success with this hardware (Zotac ION Single Core) booting from a HD
16:00
<alkisg>
wsuetholz: well I guess you can try with a live ubuntu usb stick and see if it works
16:02
<wsuetholz>
I'll see if I can manage to set up a live usb boot.. Thank you for your suggestions
16:03
<alkisg>
There's a "create a bootable usb stick" entry in Ubuntu's system > settings menu
16:04
<Gadi>
then, the question is - is it worth the trouble?
16:04
<wsuetholz>
Really?? Wow, I never noticed that before.. Am I blind or what??? Thanks again.
16:04
<Gadi>
the HDD is one of the biggest power savings in suspend
16:04
and you have none
16:04
next are fans which the bios can throttle down
16:05
(in most cases)
16:05
and the CPU, which can usually be throttled down
16:05Sarten-X has quit IRC
16:06
<wsuetholz>
Any way to just "Pause" the CPU? You still need to do memory refreshes though..
16:07
<Gadi>
you always need memory refreshes -> unless - are you planning to suspend to the server hard drive?
16:07
if you suspend to ram, you still need to keep the ram alive
16:07
<wsuetholz>
can you do that?
16:07
<Gadi>
:)
16:07
<wsuetholz>
that == suspend to server HD
16:07
<Gadi>
wsuetholz: not until you code something
16:07
:)
16:08
<Lns>
that would be a cool little hack
16:08
<alkisg>
Booting from ram seems doable... booting directly from the server's hard disk seems impossible to me :)
16:08
<wsuetholz>
That's basically poor man's hibernate

<alkisg>
*resuming

Big enough USB stick to be your swap, and then you can hibernate to that.
16:09
<Lns>
kinda brings up an interesting scenario regarding fast bootup - what if you wanted to have a "standard" suspend image, say...when booting up any ltsp client (myth* or other) for faster bootup times?
16:10
i.e. when you don't need to redetect hardware (standard setups) or go through all the bootup hoopla
16:10
<wsuetholz>
That would be great for like hardware.. But you'd still have to do some startup steps
16:10
<Lns>
almost like a live "time machine" deal
16:10etyack has quit IRC
16:11
<Lns>
sure..but overall bootup time would be reduced to suspend style bootup
16:11
s/bootup/wakeup
16:11
<wsuetholz>
Even "identical" hardware seems to have some differences that need to be checked for at boot time (from what I've read)
16:11
<Lns>
mac addy
16:12
maybe a script to parse these diffs during wakeup
16:14
<wsuetholz>
This whole discussion brings up whether what I've been trying to do with my diskless Zotac ION box is even possible.. Namely suspend to RAM.
16:14
<Lns>
Gadi: is NBD going to be replaced in LTSP at all in the forseeable future, or are we patching upstream to handle new functionality?
16:15
<wsuetholz>
Does it need to have some local storage for things to work, or is that only for suspend to disk (hibernate)
16:16vagrantc has quit IRC
16:17
<wsuetholz>
I do have a script that turns off the display by forcing the dpms to turn off the monitor. The only fan is a case fan, that I've been debating about unplugging anyways. That leaves the CPU, NIC, and Memory.. Like Gadi said.
