<map7>
Is it possible for clients to burn using their cd burner within their thin client?
00:36
<johnny>
not really
00:36
perhaps someday
00:36
it's a hard problem to solve
00:36
<map7>
what about if I run the program as a local app?
00:36
<johnny>
yes, then you can
00:37
it should see the local device, but then where are the files :)
00:37
just make sure the file chooser can perhaps point them in the right direction
00:37
instead of shoving them off in / instead of /home/user
00:37
<map7>
ok but what about permissions, is there anything I have to change in the chroot relating to permissions?
00:38
<johnny>
chroot i don't think so
00:38
i'm just trying to imaging where the files are going to go , (the temp cd files)
00:38
it defaults to /tmp, but temp on the client is mounted in ram
00:38* johnny is still waiting for the xdg user temp file spec
00:39
<map7>
I have installed brasero and xcdroast as local apps but they cannot see my cd/dvd burner
00:39
<johnny>
hmm.. they should be able to see your drive...
00:39
if you run a local terminal, can you see the drive?
00:39
<map7>
yes
00:39
and if I put in a CD with something on it I can read it through gnome
00:39
<johnny>
try burning it with cdrecord if you know how
00:39
get that working first
00:39
that way you'll know what the problem is quicker
00:40
<map7>
cdrecord as a local app?
00:40
<johnny>
probably best to try with some iso
00:40
yes
00:40
try with an ubuntu iso
00:40
iso recording is easier with cdrecord than trying to assemble it yourself
00:40* johnny doesn't like the cli interface to cdrecord
00:40
<map7>
ok yeah I've played with the cdrecord
00:41
<johnny>
and?
00:41
oh.. before.. not this time with local apps :)
00:41
<map7>
I mean I've played with it before yeah
00:41
<johnny>
sorry.. i'm kind of in the middle of other stuff at the the same time :(
00:41
but i'll try to check back in a few
00:42
brasero seems like it wouldn't be the best to run locally :(
00:42
apps that use gconf tend to have problems that require manual work to correct
00:53
<map7>
cdrecord finds the device
00:53
<johnny>
but will it burn?
00:53
if you hae a spare...
00:54
<map7>
it seems to be, the write light is flicking away
00:57
<johnny>
hmm.. well cdroast should work then too
01:03
<map7>
ok well the problem I'm having with xcdroast is permissions, I'm reading the readme now
01:04
The burning completed and I've checked the contents of the CD and it worked with cdrecord fine.
01:17
ok looks like xcdroast has a bug in it still under Ubuntu
01:18
johnny can you recommend any other cd burning program which may work on the thin client?
01:18
<johnny>
does it work normally?
01:19
on a non thin client?
01:19
<map7>
no
01:19
https://bugs.launchpad.net/ubuntu/+source/xcdroast/+bug/380144
01:19
I found that and it looks like I've got the same error
01:21
<johnny>
ah, well that would probably work if it was fixed :)
01:21
you're going to have the best luck with applications that don't depend on a desktop environment
01:22
you could try k3b locally.. it might potentially look better
01:22
but then you have install most of kde to your chroot
01:22
<map7>
so basic frontends for command line tools
01:22otavio has quit IRC
01:23
<johnny>
map7, well gconf gives us alot of trouble, i'm glad gnome folks are making it possible to work without out
01:24
map7, in my situation, i just decided it'd be better to go the thick/fat client way
01:24
of course, that's only possible if you have a decent amount of ram

hello guys
02:34ogra_ has joined #ltsp
02:35
<nesusvet>
i have some trouble with kernel after loading
02:35ogra has quit IRC
02:35
<nesusvet>
i mean "kernel panic"
02:38
I am using ubuntu 10.04
02:38
when i will try to load kernel from HDD, everything is ok
02:38
but over LTSP everything is bad
02:41
<alkisg>
nesusvet: do other clients boot OK?
02:41
<nesusvet>
yes
02:41

02:41
<alkisg>
So it's probably an issue with the specific network module?
02:41
Any other messages besides "kernel panic"?
02:42
<nesusvet>
nothing
02:42
whait
02:42
sorry for my bad english
02:43
Kernel panic - not syncing: Attempt to kill init
02:43
<alkisg>
No I mean before that line
02:43
<nesusvet>
nothing
02:43
<alkisg>
Do you know what network card that client has?
02:44
<nesusvet>
pls wait, i will try to ask my assistant. I am not near with client
02:49
maybe i can to find the name something in shell
02:49
maybe dmesg
02:50
<alkisg>
You get a shell on the client? after kernel panic?!
02:50
<nesusvet>
Broadcom NetXtreme II BCM5709 1000Base-SX (C0) PCI Express found at mem da000000, IRQ 36,
02:50
The base part the same as client
02:51
<alkisg>
Is that on the server? Which module does that use? (lspci -k)
02:51
<nesusvet>
yes it on the server
02:52
bnx2
02:52
<alkisg>
(and is that the same network card as the client?)
02:52
<nesusvet>
yes
02:54
<alkisg>
OK, you need to add that module to the client initrd.img

<nesusvet>
thanks a lot i will try
03:02
the sudo chroot /opt/ltsp/i386/ /usr/share/ltsp/update-kernels does't work
03:03
there is no file in the directory /usr/share/ltsp/update-kernels
03:03
can i make only sudo ltsp-update-kernels
03:03
?
03:03
i have made sudo chroot /opt/ltsp/i386/ update-initramfs -u
03:05
<alkisg>
You should have a file /opt/ltsp/i386/usr/share/ltsp/update-kernels
03:06
So you should be able to chroot and run it
03:06
<nesusvet>
i see only this file
03:06
update-alternatives update-fonts-dir update-icon-caches update-mime update-passwd update-usbids
03:06
update-bootsystem-insserv update-fonts-scale update-inetd update-mime-database update-pciids

03:06
update-fonts-alias update-gtk-immodules update-locale update-pangox-aliases update-rc.d-insserv
03:06
<alkisg>
It belongs to ltsp-client-core, you can't have ltsp without it
03:06
<nesusvet>
ahh ok
03:07
<alkisg>
Don't forget the chroot command in front
03:07
In other words, just paste the whole command, don't write it :)
03:08
<nesusvet>
thanks
03:12
i have installed ltsp-client-core but i still can't find update-kernels
03:12
:(
03:13
what i did wrong
03:13
/opt/ltsp/i386/usr/share/ltsp/update-kernels - nothing
03:14
<alkisg>
nesusvet: you don't need to install ltsp-client-core, it's automatically installed when you run ltsp-build-client
03:14
Do you have an i386 chroot or an amd64 chroot?
03:14
<nesusvet>
yes
03:14
<alkisg>
What do you get with this command?
03:14
<nesusvet>
amd64
03:14
<alkisg>
That's why there's no i386 then...
03:15
What do you get with: ls -l /opt/ltsp/*/usr/share/ltsp/
03:15
Paste the output in pastebot
03:15
!pastebot
03:15
<ltspbot`>

http://ltsp.pastebin.com/8PNiEgU1
03:16
<alkisg>
OK, see the update-kernels there?
03:16
That's the one...
03:16
So ok just run this: sudo chroot /opt/ltsp/amd64 /usr/share/ltsp/update-kernels
03:17
The same for the other commands too
03:17
You need to substitute i386 with amd64
03:17ogra_cmpc has quit IRC
03:17
<nesusvet>

Skipping yaboot configuration. install yaboot package if you need it.
03:17
Skipping etherboot images. Install the mkelfimage package if you need them.
03:17
<alkisg>
That's succesful output, the command ran OK
03:18
<nesusvet>
ahh ok
03:18
:)
03:18
starnge output
03:19
strange output
03:22
Thanks it's working

08:06* vagrantc ponders how people can reply directly to the right post and have it end up in the wrong thread...
08:07
<vagrantc>
how do you *do* that?
08:12
<_UsUrPeR_>
vagrantc: I have been having a lot of trouble with corrupted .deb packages being downloaded from dists recently. has this been an issue for you at all?
08:12
<vagrantc>
nope
08:12
<_UsUrPeR_>
it's been like this about 2 days for me
08:12
hmm. ok
08:12
thanks
08:12
<vagrantc>
what mirror?
08:12
<_UsUrPeR_>
main server
08:13
ubuntu 10.04 x64
08:13
hmm
08:13
ok, so I have switched interfaces on the server I am working on, I have switched internet service providers in our office, and I have switched network cables
08:13
but I am still getting hash errors
08:13
what does that sound like to you?
08:14
<vagrantc>
saw a problem a few days back with broken packages in the ubuntu archive
08:14
<_UsUrPeR_>
ahh
08:14
<vagrantc>
but sounds like this is an entirely different problem
08:14
<_UsUrPeR_>
because right now, I can't run ltsp-build-client without having corrupt .deb packages
08:14
<vagrantc>
i.e. the mirror was doing it's job fine, the content it was serving was borked
08:15
<_UsUrPeR_>
yeah
08:15
I had that a couple days ago
08:15
<vagrantc>
but that was just with the kernel package having impossible dependencies
08:15
<_UsUrPeR_>
hmm. the issue I was having was also with the kernel package, but the md5sum check was coming back as incorrect
08:15
that actually just resolved itself yesterday for me
08:15
<vagrantc>
_UsUrPeR_: you behind an http proxy? transparent or otherwise?
08:16
<_UsUrPeR_>
no. As a test, I put this directly off our router on our backup internet connection
08:16
which is through a cable company. There isn't even a firewall in the way
08:17* vagrantc hunts down breakfast
08:17
<vagrantc>
good luck

Nope.

johnny: time for a quick question?
11:28
cause the funtoo stages are no longer offered in tar.bz2 format, but in tar.xz
11:28
we still offer a fallback stage download for those
11:29
but quickstart has no support for tar.xz
11:29
so i was thinking, either remove the funtoo fallback
11:29
or make some changes in quickstart
11:31
i prefer to remove the funtoo fallback, because it's incompatible with ltsp anyway
11:35
<redbaritone>
I'm interested in building my own thin clients, but Googling for pertinent web sites is fruitless, because any time you combine the words "build" and "linux", they're talking about building your own distribution. Are there any good web sites to go to, to find out what hardware people are using to build their own thin clients?
11:36alkisg has joined #ltsp

<grantk>
I like intel atom mobos w/ a small case and some memory redbaritone
11:36
can come in around $130.00 if you do not need hardisk
11:36
<vagrantc>
redbaritone: anything supported by the distro that has pxe boot should work
11:37
<johnny>
redbaritone, just dont' add linux
11:37
the important thing is what video chipsets are there
11:37
everything else is usually pretty good
11:37
it's video that you have to worry about
11:37
<knipwim>
i was thinking of HP's t5325 with ARM proc
11:37
<johnny>
redbaritone, i just went with msi wind nettops
11:37
knipwim, sure, i agree
11:38
<knipwim>
check
11:38
<johnny>
knipwim, so are you hearing that dracut will be finished soon for gsoc?
11:38
<knipwim>
yup
11:38
<redbaritone>
It's just that I'm having a hard time finding _appropriate_ hardware. What case "style" should I use, mini-itx? I'll take individual link, but I'd prefer a good web site that has those links already.
11:39
<knipwim>
i'm following aidecoe's blog
11:39
<redbaritone>
Link?
11:40
Thanks for the tip on the video chipset. I'll watch out for that.
11:42
Is there a link to aidecoe's blog?

Anyone know what shell runs get_hosts? I am getting errors with echo -e option.
12:45hawkI has quit IRC
12:47
<johnny>
what shell?
12:48
get_hosts is an ltsp option, you probably set something invalid in your lts.conf
12:48
either that, or the code is buggin in the clustering case
12:49
<grantk>
well, I guess I should not call it a shell, sorry, I was watching the boot logs and was seeing the get_hosts script fail with an error for echo -e

I see an Intel BOXD510MO Intel Atom mini-itx Mobo on Newegg for $77. It has Intel GMA 3150 onboard video chipset. Has anyone here used this, or something similar to it, for building a thin client? Any problems? Other recommendations?

I am getting an error when creating my thin clients
13:30
http://pastebin.org/428276
13:30knipwim has joined #ltsp
13:31
<atomic007za>
seemingly a package is corrupt
13:31
how could I rectify this?
13:32
<muppis>
Run sudo chroot /opt/ltsp/i386 apt-get update
13:33
<atomic007za>
I am running a 64 bit OS with x86 clients.
13:33
so I can still do this?
13:33
<muppis>
Yes.
13:34
<atomic007za>
chroot: cannot run command `apt-get': No such file or directory
13:34
I get this
13:35Blinny has joined #ltsp
13:35
<muppis>
Then there is something totally wrong under that directory.
13:36
Try aptitude instead of apt-get
13:39
<atomic007za>
same thing
13:39
chroot: cannot run command `aptitude': No such file or directory
13:39
chroot: cannot run command `aptitude': No such file or directory
13:40
<muppis>
Hmm..
13:41
<atomic007za>
evn if I do: sudo cp /etc/apt/sources.list /opt/ltsp/i386/etc/apt/sources.list
13:41
I get: cp: cannot create regular file `/opt/ltsp/i386/etc/apt/sources.list': No such file or directory
13:42
<muppis>
What you have under /opt/ltsp/i386 ?
13:42
<atomic007za>
debootstrap/ var/
13:43
<muppis>
Ouch..
13:43
<atomic007za>
debootstrap/ and var/
13:43
is my sytem finished?
13:43
<muppis>
Then there's no choice than try to run ltsp-build-image again.
13:44
<atomic007za>
with or with out --arch i386
13:44
<muppis>
With, if you want x86.
13:45
btw, you can put /etc/ltsp/ltsp-build-image.conf and /etc/lts/ltsp-update-image.conf line ARCH="i386" so you do not need remember use --arch i386 in command.
13:46
<atomic007za>
cool will do it now
13:50

13:53
I have a ltsp-build-client and a ltsp-update-image, but no ltsp-build-image. And if I run the ltsp-build-client I get the above error
13:53
should I have a ltsp-build-image?
13:54
<vagrantc>
ltsp-update-image
13:55
<atomic007za>
but I have no client
13:55
<vagrantc>
sounds like ubuntu's mirrors are (hopefully temporarily) messed up
13:56
well, you start with ltsp-build-client ...
13:56
which downloads files from ubuntu's mirrors...
13:56
and the mirrors are seemingly broken...
13:57
<atomic007za>
:-(
13:58
<muppis>
atomic007za, my bad. Names of .conf -files are same as related program.
13:58
<atomic007za>
np
13:59
vagranttc: So does this mean I cant build a client?
13:59
Is there a way I could try a different Mirror?
14:00
<muppis>
fi.archive.ubuntu.com works.
14:00
<atomic007za>
ok sorry, but how do I import that mirror?
14:01
<muppis>
You must edit /etc/apt/sources.list
14:01
<atomic007za>
I hav till the morning to fix this or they pull the plug
14:01
cool will start there

Is my system completely broken?

Running with sudo ?
14:17

Try this, I just tried it and it works for me: sudo ltsp-build-client --arch i386 --mirror http://gr.archive.ubuntu.com/ubuntu
14:17
If it doesn't work for you, yeah there's something broken, e.g. the network or a proxy server or something

Hi...

If my server don't work in the ssh port 22, i need to chroot, configure the right port in the /etc/ssh/ssh_config? or there is other way?

anyone know how toturn off flowcontrol for a realtek 8169 gig NIC?

ethtool doesnt work

No can't do
16:32
The realtek driver doesn't yet support it
16:32
<atomic007za>
damn
16:32
<alkisg>
If you compile some version from their site and manage to do it, I'm all ears
16:32
I've been advicing teachers here to buy intel instead
16:32
(7 € vs 25 €)
16:32
<atomic007za>
ic
16:33
<alkisg>
If you have a good managed switch maybe that supports turning off flow control
16:34
<atomic007za>
ok well I have 2 , and I think I migt have chatted to you the other night when I was not sure if the network was actually running @ a gig speed
16:34
damn
16:34
<alkisg>
netperf or iperf running locally on the client is the best way to verify
16:35
Each client should be able to cause 100 mbps of traffic, up to 10 clients
16:35
So if with 3 clients running netperf you only get 100mbps, then flow control is on...
16:36
(as opposed to 300 mbps, measured on the server nic)
16:36
<atomic007za>
so I run it on the thin client and watch iftop on the server?
16:36
ic
16:37grantk has left #ltsp

16:38
<alkisg>
Either iftop or the netperf server
16:38
(you need the netperf or iperf server anyway...)
16:38
<atomic007za>
ok, I will install it
16:39
just hope they are not running @ 10 mbps
16:39
<alkisg>
Heh
16:39
<atomic007za>
clints were so slow the other day
16:39
*clients
16:39
<alkisg>
flow control == off is totally worth giving 25 € to buy an intel nic for the server. It'll speed up the network 10 times.

alkisg: I have a gig network
18:36
<alkisg>
atomic007za: so?
18:36
Are your clients gigabit?
18:36
<atomic007za>
but if the flow control is on
18:37
does it still limit me as far as my 100mbps clients go
18:37
<alkisg>
Flow control is only a concern on mixed gigabit / 100mbps networks
18:37
If _everything_ is gigabit, you don't need to bother with it
18:37
But if your clients are 100mbps, then it's a problem
18:38
<atomic007za>
ok, so if I upgrade to intel nics I will see a even faster boot up?
18:39
(and turn flow ontrol off
18:39
)
18:39
*control
18:39
<alkisg>
So, what clients do you have? gigabit or 100mbps?
18:39
<atomic007za>
100
18:39
<alkisg>
So you don't have a gig network
18:39
You'll see 10x times faster network speeds
18:39
How many clients do you have now?
18:40
<atomic007za>
switches and server is, 35 clients
18:40
switches and server is gig , 35 clients(100mbps)
18:40
<alkisg>
OK, if you boot 4 clients now and see the speed,
18:40
...and then turn flow control off and boot all the 35 clients,
18:40
the speed will be about the same
18:41
<atomic007za>
no 4 clients now are fast, 35 slows down
18:41
<alkisg>
Right. So they'll be about 10 times faster.
18:41
<atomic007za>
cool
18:41
<alkisg>
(network speed, not cpu-wise)
18:41
(i.e. boot speed will be like when you boot 4 clients now)
18:42
<atomic007za>
cpu i7, 35 pc it sits @ 15%
18:42
wow
18:42
<alkisg>
No I mean the client cpu
18:42
<atomic007za>
oh
18:42
range from cel1.6 and up
18:42
<alkisg>
E.g. some really fast clients I have boot in 13 seconds
18:42
...while ancient ones need 1.10
18:43
<atomic007za>
oh ok I see what you mean
18:44
want to try booting 4 slow pc now to see, will be intersting test
18:44
<alkisg>
Right, that's the speed you'll see later on when you turn off flow control while booting all the 35 clients at once

what maintenace needs to be done on the server. eg, the users do a hard shutdown @ the end of the day, do I have to clear temp files?
19:08
<alkisg>
Their processes should be killed after 2 hours
19:08
Except for some evolution-server stuff which you'd need to manually kill
19:08
Temp files are only a problem if you enable NBD_SWAP, at least that I know of

smallest seems to be 1.7 cel, 128m RAM
19:28
<alkisg>
You could make a fat chroot which would automatically boot the low-end clients as thin, and the high-end as fat, offloading CPU from your server
19:29
That would require maintaing programs inside the chroot, but imho it's worth the effort
19:30
<atomic007za>
will look into it
19:31
and ndb is the way to go, not nfs
19:31
?
19:31

NBD is faster. NFS is handy if you need to do a lot of chroot changes, e.g. while debugging etc

I must say, its interesting, when I switch the new pc on with the old they take a long time to load vmlinux

dropped the "mii-diag eth0 -A 0x1e1" on the server

so technically it could be done?

I think so, yeah, at least that's what the driver sources say
19:54
It's just that they don't support ethtool yet, so I don't know how
