<Q-FUNK>
ogra: I have figured out a way to generate 3 images in the update script
04:24
pxe, nbi and elf. nbi uses the old nbi tool for deprecated etherboot implementations, elf uses this new tool, while pxe uses the existing method
04:24
<ogra>
well nbi defaults to mkelf anyway
04:24
<Q-FUNK>
which, as you might recall, failed for the dbe60
04:25
<ogra>
we didnt use mknbi since several releases how do we make sure that doesnt clash ?
04:25
but works on all others :)
04:25joebake1 has joined #ltsp
04:25
<Q-FUNK>
what was the instruction of making images for older etherboot using nbi, then?
04:26
<ogra>
a proper thing would be to replace mknbi ... but then we need the guarantee that this other tools works with all other implementations
04:26
mkelf-linux ....
04:26
<Q-FUNK>
not really
04:26joebaker has quit IRC
04:26
<ogra>
for main inclusion we do
04:26
thats the way ubuntu works
04:26
<Q-FUNK>
if we have pxe, nbi (mknbi) and mkelfImage, we have 3 targets. that's what i have now.
04:27
<ogra>
one tool for the task ... the one that matches the majority
04:27
well, mkelfimage does the same mkelf-linux does but omits the BIOS calls as i understand it
04:27
<Q-FUNK>
the only tricky part is configuring the dhcp server to sort out which image to send, between nbi and elf

<ogra>
(sorry, still 1600 mails to go, i didnt read them yesterday due to CD testing duties)
04:28
<Q-FUNK>
oh :|
04:28
well, you'll get there :)
04:28
<ogra>
yeah
04:29
<Q-FUNK>
but I still think that getting -amd and this new tool into main would be desirable
04:29* ogra waits for the spam filter to finish ... should cut that in half :) )
04:29freet15 has quit IRC
04:29
<Q-FUNK>
LOL
04:29
<ogra>
-amd will be in main for the release
04:29
<Q-FUNK>
great! :)
04:30
<ogra>
the tool is a question of code qualit, convincing the TB about the need for duplication in main etc ...
04:30
oh, and indeed it will get a full security review
04:31
<Q-FUNK>
that's just it, there's no duplication. mkelf produces a tagged elf image which relies upon bios calls, while mkelfimage produces an elf image that doesn't use any bios call.
04:31
code quality is ok, but their makefile is needlessly complicated and buggy. i have to do a lot of silly things to get this thing to build cleanly every time.
04:34
<ogra>
hmm, k
04:34
we could advetise it as full linuxbios compatibility :)
04:34
<Q-FUNK>
:D
04:34
<ogra>
marketing would like that :)
04:35
<Q-FUNK>
here, I'm gonna flash eproms for a couple of old ISA cards, using a purposely cripled ethrboot.org without pxe emulation (only bootp and tftp support), on monday.
04:36
this should give us a good idea of whether mkelfImage can safely replace mkelf-linux or not on traditional hardware.
04:38
dbe60 already fails if i use this, but thankfully we can build an up-to-date image that works the exact same way as the one on the dbe61, so it's no big deal
04:39
the strange thing is that mkelf-linux should work as it is on the deb60. we used that succesfully before.
04:39
<ari_stress>
hello, is it possible to install additional packages into ltsp5? i'm on feisty
04:39
<Q-FUNK>
ari_stress: the chroot or what people see on the desktop?
04:40
<ari_stress>
Q-FUNK: yes, i've chrooted to /opt/lts/i386
04:40
i'm trying to install xfce on it
04:40
<Q-FUNK>
xfce is outside the chroot
04:41
<ari_stress>
oh? you mean i should install it on the host ubuntu instead? not the chroot/client env?
04:41
<Q-FUNK>
exit the chroot and install the xubuntu metapackge
04:41
on the server host, yes
04:42
the chroot is only used to bootstrap the thin client
04:42vanya has joined #ltsp
04:42
<ari_stress>
ok, thanks Q-FUNK :D.
04:42
you make it clear :D
04:43
<Q-FUNK>
the chroot basically provides just enough of a basic ubuntu system to start the thin client and configure X, then the login manager connects to the server
04:43
so, any application you wanna see on the desktop, you install _outside_ the chroot.
04:44
<ari_stress>
cool
04:44
anyway., ltsp 5 seems very different than 4. it seems to be very simple.
04:44
<Q-FUNK>
yes indeed
04:45
<ari_stress>
it even doesnt include examples in the lts.conf anymore?
04:45
where can i get reference for any parameter in lts.conf?
04:45
<Q-FUNK>
ogra: that reminds me, would it be possible to include ntpdate in the default chroot and to start the network earleir, to avoid all those "timestamp of foo is in the future" messages?
04:46
ari_stress: if you really need to configure anything there, there's some ubuntu tutorials which show the options. however, since ltsp5, almost everything is done automatically, including guessing the monitor's resolution and graphic card capabilities.
04:48
<ari_stress>
Q-FUNK: you mean we dont need to put anything else in lts.conf anymore? or does lts.conf from v4 still apply in v5?
04:49
<Q-FUNK>
about older v4 config applying in v5, that, i wouldn't know
04:50
<ari_stress>
so, let's say i plug an usb printer in the client. it will magically detected by ltsp?
04:53
<Q-FUNK>
usb sticks are, but I never tried with a printer
04:54
<ogra>
Q-FUNK, i dont want an additional port open on te server ...
04:54
Q-FUNK, the plan was to recieve a timestamp with the locale and session list in ldm
04:54
and set the clock from there
04:56
<Q-FUNK>
ogra: some thin client hardware doesn't have any RTC battery. we could compensate by setting the clock early with ntpdate.
04:57
<ogra>
Q-FUNK, yes, but have another open port to take care of
04:57
ntpdate was an should stay optional
04:58
its trivial to install if you want it
04:58
<Q-FUNK>
installing it is trivial, but it barely helps because the network starts so late in the boot process
04:59
I agree to keeping it optional, but network start would still need to be earlier than it is in the boot process.
05:16
<ogra>
the networks starts from initramfs
05:16
and doesnt change after that
05:16mistik1 has quit IRC
05:19* ogra wonders if thats understandable for usual LTSP users https://help.ubuntu.com/community/UbuntuLTSP/LTSPWithoutNFS
05:31
<Q-FUNK>
ogra: ok. not the case here on etch. it starts much later.
05:31
and ntpdate is run from if-up.d
05:34
<ogra>
right
05:34
but if yu have an nbdroot it *cant* start later
05:34
dont judge by the network initscripts ;)
05:35
you would use / if they had any effect n the interface
05:35
<ari_stress>
hm.. what is the max amount of ram supported by feisty? to be exact, how many ram is needed to support 80 LTSP clients that open openoffice?
05:36
<ogra>
ari_stress, tons :)
05:37
nah, i'm lying
05:37
if all just use the same program there is a lot ram shared
05:37
<ari_stress>
ogra: is there any formula to plan for the ram? will 40gb enough?
05:37
<ogra>
especially for ooo
05:37
it really depends on the other stuff you run ;)
05:38
a ubuntu gnome desktop where you want to use ooo eats usually 128M per user
05:38
256 are needed to run te server itself
05:40
<ari_stress>
128M x 80 = 10,240M, nice :)
05:40
<ogra>
given that a lot will be shared (even a lot of the desktop apps will do that) you could even get through eith less
05:40
*with
05:40
but make sure to run a -server kernel flavour on the server
05:40
the -generic one wont address more than 4 i think
05:41
(4Gig that is)
05:42
<ari_stress>
ogra: how to use another kernel in ltsp? is it installed in the host or the chroot?
05:42
<ogra>
you only need it on the server
05:42
<ari_stress>
ok
05:42
<ogra>
the client kernel should always be -386 since many clients only speak 568 instruction sets ...
05:43
(-386 is compiled for 486 and above, -generic for 585 and above)
05:43
errg
05:43
<ari_stress>
when this project is done, i'll write a success story on ltsp.org
05:43
:)
05:43
<ogra>
-generic for 686 and above indeed
05:43
ari_stress, cool 1
05:43
!
05:44
i played a bit with the -lowlatency flavore for thin clients, but that didnt have any big speedup effect ...
05:44
<ari_stress>
ogra: you are one of the ltsp developers, right?
05:45
<ogra>
after gutsy released ad we have the ubuntu mobile flavour out i'll have a look at their kernel, that might actualy speed up :)
05:45
yep
05:45
vagrantc, sbalneav and me are usually doing the main work ... and there is a bunch of occasional patch committers in here :)
05:46
<ari_stress>
cool
05:47
i always admire developers
05:47
i wish i could do some code
05:47
<ogra>
and not to forget about jammcq, he's our lead and brain :)
05:47
well, if you find things you want to fix (even if its a one liner) let us know about ;) it might be the solution to a longstanding prob we never saw, who knows
05:48
every small bit counts ;)
05:50
<ari_stress>
ok :)
05:50
<ogra>
btw, would you understand the link i pasted above ?
05:50
https://help.ubuntu.com/community/UbuntuLTSP/LTSPWithoutNFS
05:50
since you are not a coder you might match the audience i wrote it for :)
05:51
(well, its rather for teachers that do admin work and have at least a slight understanding, but i'm tired to answer the questions over and over ;) )
05:53
i want it to be a foolproof explanation, but i think i'm to much into it to even explain it properly for non tech people
05:53
<cliebow>
ogra:nice job with that page..
05:54
<ogra>
thanks :)
05:54
feel free to change it where you find errors/misexplanations
05:54
<ari_stress>
i'm looking at it,. sorry many interuptions here :D
05:55
<cliebow>
ogra:you were saying next door you have a smoothwall deb??
05:55
<ogra>
cliebow, on the server-addon CD, yes
05:55
<cliebow>
that is smoothie 2 or 4?
05:55
whoops 3
05:55
<ogra>
i'll need to set that up once to write a proper howto :)
05:56
<ari_stress>
ogra: the link is cool. i can understand it. but maybe because i;m a sysadmin?
05:56
<ogra>
ari_stress, thats enogh for a start :)
05:56
argh
05:56
cliebow, its indeed not called smootwall
05:57
its shorewall
05:57
:)
05:57
<cliebow>
ok..now i understand
05:57
<ogra>
mark loves it :)
05:57
thats why we have it in main
05:59
<cliebow>
"In the past we used a read-only nfs mount to /opt/ltsp/i386 as a client's root file system.We now create a squashfs image of that filesystem."
06:00
does that explain to those who have used early ltsp?
06:00
<ogra>
i hope so
06:01
i hope debian will follow (its still possible to use nfs, thats why we also still have the chroot in /opt/ltsp)
06:01
so its up to them to either switch over or keep the old setup
06:01
its a two line change to revert
06:01
<cliebow>
yep..
06:02
<ogra>
Q-FUNK, got to the mail thread (finally)
06:02
"then there could be a new define: LINUXBIOS=yes"
06:02
thats what i thought
06:02
we should merge it into mkelf-linux
06:02
<Q-FUNK>
mkelf-linux simply won't work.
06:03
there's nothing to merge.
06:03
the linuxbios dev already established that a separate new tool was needed
06:04
ideally, mknbi's mkelf-linux would have incorporated the new code and allowed --options to disable bios calls for linuxbios.
06:04
in practice, this didn't happen
06:09
about mkelf-linux, it produces images that the deb60 doesn't like, on Etch.
06:10
ah, define for which of the two tools to use. yes. in lts.conf ?

06:14kaminski-ltsp-br has quit IRC
06:14kaminski-ltsp-br has joined #ltsp
06:18
<ogra>
lts.conf doesnt affect the image building
06:18
<Q-FUNK>
where would we configure this then?
06:19
<ogra>
/opt/ltsp/i386/etc/ltsp/update-kernels.conf would be the place for the update tool ...
06:19
but i want it automated
06:19
no fiddling in config files for users
06:20
so for the switch that should rather be an option to ltsp-build-client
06:20
not a variable in a file
06:20
<Q-FUNK>
that sounds good
06:21
<ogra>
nyway i'D like to hear indrek about the opportunity to merge the tools
06:21
(i just sent a mail)
06:23
<Q-FUNK>
merging the tools would imply becoming upstream for both mknbi and mkelfImage
06:23
then merging them
06:24
this needs feedback from the community at large at linuxbios and etherboot.org
06:24
if they have no problem with merging this, great.
06:29kaminski-ltsp-br has quit IRC
06:29fernando1 has quit IRC

we dont need to become upstream for both if its possible to just patch mknbi ;) we need to become upstream for that patch though

Q-FUNK, well, the gutsy version works ... might as well be a kernel thing
07:18
<Q-FUNK>
kernel loads, but somethign goes wrong with the initrd
07:18
however, with mknbi-linux, both load as exepcted
07:23jammcq has joined #ltsp
07:23
<jammcq>
g'morning all
07:26
<ogra>
hey jammcq
07:26
good suggestion for the lts.conf ... i'll do it that wax
07:26
*way
07:27
<jammcq>
I shoulda done that years ago, so I could change the name from lts.conf to ltsp.conf
07:27
<ogra>
yeah
07:27
should we do that alongside ?
07:28
<jammcq>
umm, well. we could keep kicking ourselves, saying we "shoulda" done it :)
07:28
<cliebow>
where will lts.conf reside ?
07:28
in tftproot?
07:28
<jammcq>
ltsp == linux terminal server project. lts = long term support
07:29
<ogra>
cliebow, yes, as described on the wikipage i posted before
07:29
<cliebow>
good..my test server calved on Wednesday..so im just reinstalling at school..

07:43

i'm not sure anymore if it was "illegal" or terroristic"

sadly trees over 10m are protected in germany ...

Is there a way to broadcast a message to all the thin client displays from the root
09:37
account on the server?
09:38
NX has this neat command nxserver --broadcast "Everybody pretend you're on Windows"
09:46
<sbalneav>
joebaker: yeah, I beleive that TCM will do that for you
09:48
<Blinny>
I'd love to use that. What is TCM?
09:49
<sbalneav>
Thin Client Manager
09:49
<Blinny>
Is this an ubuntu-specific thing?
09:51
<sbalneav>
I think so, but it's fairly easy to do outside of a tool
09:51
All you need to do is find out the DISPLAY of the client
09:52
set the XAUTHORITY environment variable to point to the users xauth file (you'd do this as root)
09:52
then you could just use something like zenity or whatever little gui box to pop up on the client's display
09:53
<gvy>
err... gxmessage?
09:53
<sbalneav>
just march through all the logged in users.
09:54
gxmessage, xmessage, Xdialog, zenity, etc.
09:54
there's a tonne of them.
09:55
Probably be a 10 line shell script. I beleive someone posted one on the mailing list a few years ago.
10:01
joebaker, Blinny: does everyone on your servers use the same window manager?
10:02
<jammcq>
for it to work, you MUST disable X access control
10:02
<Blinny>
sbalneav: Yes.
10:02
<jammcq>
which opens a security whole
10:02
<sbalneav>
What, you mean xhost +?
10:02
<Blinny>
Well, I haven't rolled it out officially yet. Still trying to keep clients from crashing randomly.
10:03
<jammcq>
no, you'd have to set it in lts.conf
10:03
or get each user to do 'xhost +'
10:03
but it's easier in lts.conf
10:04
<sbalneav>
Even if you set the XAUTHORITY?
10:04
hmmm, let me check...
10:04
<jammcq>
you want some NON-YOU user to be able to display a message on YOUR screen?
10:04
you better give them access
10:05
this conversation ALWAYS starts with "eh, should be a 10 line script"
10:05

heh

Eventually, everything will be a 10-line script.

<monteslu>
hey guys, there's a CLI utility to check if an ethernet cable is plugged in, does anyone remember the name of it?

10:06
<monteslu>
ahhh, mii-tool
10:06
that's the one, thanks
10:06
<jammcq>
i've heard that ethtool is better, but i've had mixed results with both
10:07
seems on the same machine, they can both report different things

mii has worked for me in the past, but I can never remeber the name of it

10:09
<gvy>
jammcq, ethtool isn't "better"
10:09
there are three ioctls for querying interface status
10:09
<sbalneav>
As root, btw
10:09
<gvy>
and different drivers do different job at [some of] them
10:10
so it's better or worse on a case by case basis...

there's ifplugstatus btw

10:28
<ari_stress>
is it possible to setup dhcpd.conf with dns dynamic update in ltsp configuration, because when i set it up for dynamic update, the client failed to TFTP

10:35
yeah I know xclock is just an example, but if I could substitude gnome-wall "We're going down!" in for 'xclock' then it really is a 2-line script
10:35
(if there is such a thing as gnome-wall)
10:35
<sbalneav>
Well, there's no such thing, that's what we're talking about.
10:36
ok, so, got a user handy for testing?
10:36
<Blinny>
Does my own box count?
10:36
<sbalneav>
No
10:36
We want a terminal logged in as another user
10:36

Uhh yeah one moment.
10:36* gvy dives in a box with test users and picks one
10:37
<Blinny>
Okay ready.
10:37
<sbalneav>
so, what's the window manager? Gnome?

No, I substituted b/c hostname/username is the same in this instance
10:42
DISPLAY=textbox:0.0
10:42
(:
10:42
<sbalneav>
ok
10:42
cat /proc/2111/environ | tr '\0' '\n' | grep XAUTH
10:43
<Blinny>
XAUTHORITY=/tmp/.gdmB3X3VT
10:43
<sbalneav>
Odd place to put it. Usually it's $HOME/.Xauthority
10:43
ok, well lets run with it, see what we get.
10:44
<Blinny>
There is one of those too.
10:44
(for this user)
10:44
<sbalneav>
So, lets run (as root):
10:44
DISPLAY=textbox:0.0 XAUTHORITY=/tmp/.gdmB3X3VT zenity --info --text "Oooga Booga"
10:45
<Blinny>
Do I run this on the test box, or from another sending box where I have a root console
10:45
<sbalneav>
From the root console
10:45
<Blinny>
Ooga booga popped up
10:45
<sbalneav>
perfect.
10:45
<Blinny>
Noice.

Oh, okay. Rock on.
10:47
<Q-FUNK>
this would be a nice fewture to get packaged by standard
10:48
in gnome generally speaking, but even more so on LTSP, where a reboot could kill a number of user's work.
10:51
I've always wondered if "reboot" cold be patched to have an /etc/reboot.d/ and execute whatever it finds there, such as the above script idea
10:52
<Blinny>
reboot is just a symbolic link to halt. Change the symbolic link to run a shell.
10:52
:s;ll.;script.
10:52
<ltsppbot>
"sbalneav" pasted "notify all" (8 lines) at http://pastebot.ltsp.org/222
10:53
<sbalneav>
./scriptname "ooga booga" would be the invocation
10:53
it's very rough, you can clean it up a bit.
10:53
Q-FUNK: We have the feature in TCM
10:53
This is just a quick standalone hack.
10:54
As for the reboot.d, that's already been done.
10:54

10:56
Q-FUNK: Dunno.
10:57
<Q-FUNK>
sbalneav: those are run during shutdown. I'm taling about a directory of tasks to execute before launching the shutdown.
10:57
<Blinny>
Won't taking out that line not set the display though?
10:57iMav has joined #ltsp
10:58
<Blinny>
(meaning it won't iterate through logged-in users)
10:58
<Q-FUNK>
right now, "reboot" already sends a wall to users logged on any console. we'd need that wall to also go to desktop users via their notification area, using zenity and the equivalent kde tool.
10:59
<ltsppbot>
"sbalneav" pasted "fixed" (7 lines) at http://pastebot.ltsp.org/223
11:00
<Q-FUNK>
alternately, gnome and kde would need a standard way of catching wall messages and displaying them.
11:00
<sbalneav>
Q-FUNK: Just number it so that it's the first thing run on shutdown, and do a "sleep (whatever)" after to halt the shutdown process for a bit
11:00
<Blinny>
sbalneav: Yeah, the only computer getting the popup is the testbox. Another box got it once, but the terminal I'm logged in at hasn't yet, even if I run the script from testbox.
11:00
<sbalneav>
There's command line tools to put things in the notification error.
11:01
They have to click on the ok, before the next one will run.
11:01
heh
11:01
put a & after the zenity
11:01
to background it.
11:01
Like I say, I just banged it off.
11:02
<whiprush>

i.e. you've released your updated script under the GPL license?
13:57
<shale_>
nothing so official
13:58
it's just "out there"
13:58
should i put a GPL disclaimer on it?
13:58
<sbalneav>
heh, ARE you willing to release it under a GPL license so we can re-include it in ltsp5?
13:58
<shale_>
of course, it's mostly based off the previous script from 4.2 anyway
13:58
how do i go about GPL'ing it?
13:58
<vagrantc>
Gadi: you sure there isn't just a squashfs-modules package ?

no - its just a module

I need to add it to my initramfs mods to have it in there
13:59
all better
13:59
<sbalneav>
OK, well, if you basically allow us to re-include it in LTSP5, it becomes gpl. Why not add some comments to the script with your names on it so you get attribution?
13:59
something like;
14:00
# mods to Gadi's rdesktop script by:

Just wondering, because it seem ackward for everybody to use pastebot, then work on things,
14:12
pasting it back and forth, then notifying , etc... Sort of like a gabby server only with
14:12
authentication based on google account login.

here's a msg from my sysadmin who wrote the script: "tell the LTSP guys I love their work and wished that Windows would get on the ball and get a fuse file system implementation going."

We mainly use SCCS for doing collaborative stuff. Most of us use bzr
14:14
<joebaker>
I've never gotten much past learning the patch and diff commands. I don't use them
14:14
much either.

Hello,

ZoOl007_: hello
14:18
shale_: Let me know when you've got the new version up, and I'll put it in my tree.

<ZoOl007_>
... what I wanted to ask. I just set up a test lab in a vmware workstation6 an I have ltsp working on ubuntu 7.0 server. Vmware uses vmware-tools. It speeds up networking a lot. I can install it on the server vm, but is there any way to get the thin clients to use their driver. At the moment they are booting over 10mbit...
14:22
<shale_>
sbalneav: ok it's updated: http://akgeeks.net/ltsp-w2k3

<zodman>
someones know how to disable ipv6 on xdm ?
14:28
<sbalneav>
ZoOl007_: Well, you could do it, I suppose, but one assumes you're just TESTING it in vmware, and will have a real rollout at some point?
14:31
shale_: pushed up to my tree on launchpad.

14:33
<Blinny>
heh
14:33
<shale_>
so does that mean it'll be in the next ver of ltsp5?
14:34
<ZoOl007_>
I'm testing... and I'm actually rather new to linux. In my real life I'm a windows sysadmin. You know... ever since I installed Ubuntu I never ever booted my pc in windows. That means something. I read your article regarding the w2k3ts. Impressive... I'm going to try that.

Have pxebooting setup on one system and it works fine. I am setting it up in another system and dhcp works, the requets to tftp happen and the tftp server even sends back the first packets. The file will not transfer. Connecting locally though it transfers fine. tcpwarppers is not in use and there is no firewall running. AThe configs are identicle (literally copied from previous env). Anyone have hints on what is wrong with tftp
16:01
? TIA
16:01
There are no network errors and all other network services work fine on that server. ie: apache, ssh, etc. File transfers via scp are normal speeds...

I have verbose logging on and see no permission denieds or files not found etc. I even tried screwing up the perms and removing files to ensure it would indeed log such things and it does.
