Channel log from 4 July 2007   (all times are UTC)

00:03* vagrantc_ concurs with MrMoo's assesment of the situation
00:03
<chupacabra>
i never saw a switch like that
00:04
mostly self contained
00:05
<jvin248>
Yes, PXE seems to work. Breakdown seems to happen at the second switch (client attached to switch1/port3 just booted up. a third Client on switch2/port4 just hung).
00:05
<chupacabra>
prolly dhcp.conf
00:05
<jvin248>
What I have are non-dedicated clients - so they need IP addresses from the modem to do Linux/windows on their own as well as other times LTSP. So some network thinking yet...
00:06
<vagrantc_>
put two network cards in your LTSP server, and configure your server to do NAT
00:06
<chupacabra>
not a good idea
00:07
<vagrantc_>
or, disable your modem's DHCP server, and just have your LTSP server handle DHCP.
00:07
<chupacabra>
set up dhcp to give them the same addy everytime
00:07
exactly vag
00:08
<jvin248>
The LTSP server is not on all the time (so regular users will have fits with no Internet access)... the server has a static IP address currently.
00:09
<vagrantc_>
or, configure your modem to hand out the appropriate information for LTSP ... but not all routers support arbitrary DHCP options, or the options needed for LTSP
00:10
or ...
00:10
<jvin248>
what information for LTSP should I look to hand out?
00:10
so I can check the modem?
00:10
<vagrantc_>
root-path and next-server
00:11
root-path a.k.a. dhcp option 17
00:11
don't know the number for next-server
00:11
<jvin248>
I don't think I saw those as options, could there be another name?... ok not sure I saw "option 17" in the modem either.
00:12
<vagrantc_>
most likely, there's no way to do it
00:12
but i have seen some that allow you to specify arbitrary options based on the numbers
00:13
but they are rare
00:13
<chupacabra>
ltsp is easy to debug
00:14
unless it is wack
00:15
<vagrantc_>
jvin248: which linux distro is this ?
00:16
<jvin248>
kubuntu 6.10
00:17
<vagrantc_>
if your PXE clients only respect DHCP servers that hand out the filename option ... you can configure pxelinux.cfg/default to tell it which server to use.
00:17
<jvin248>
modem doesn't list any options to change regarding root-path, next-server, or option 17. I had tried the "authoritative" option in LTSP dhcp server but that didn't seem to work.
00:17
<vagrantc_>
really, you need a real DHCP server.
00:18
and disable the modem's DHCP server.
00:18
anything short of that, unless you really know what you're doing, is going to be headache.

<jvin248>
Where's the pxelinux.cfg file? I searched the /opt/ and /etc/ folders (thought it would be in ltsp there).
00:23
<MrMoo>
tftpboot / lts / * /
00:31
<jvin248>
How about this.. I make the LTSP server DHCP "authoritative" and use "option root-path "IP:/opt/ltsp/i386"" where IP is the LTSP server static IP? That way when the machine is off the modem can hand out IPs?
00:31
Still didn't find the pxelinux.cfg (though my dhcp config file on ltsp server shows path should be pxelinux.0 but I don't see the file...
00:33
clip from ltsp dhcpd.conf ... if pxeclient then ... filename "/ltsp/i386/pxelinux.0";
00:37
(googling) found "http://www.naos.co.nz/papers/diskless/examples/pxelinux-config.txt" if I save a modified version of that as pxelinux.0 can that direct clients?
00:38
<cyberorg>
jvin248: you need to save it as /tftpboot/pxelinux.cfg/default
00:44
<jvin248>
ok. I found /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default! it has one line: "DEFAULT vmlinuz ro initrd=initrd.img quiet splash" ... so add with correct IP and maybe verify directories "APPEND root=/dev/nfs nfsroot=192.168.254.10:/var/wsroot"?
00:45
(add line copied from the above link)
00:54
Well, you've given me some things to think about and experiment with. too bad I'm tipping over sleepy and have to go. I'll leave the log on if you have some other ideas I should try. Thanks!

hi
06:53
I need few explanation about LTSP
06:54
I just installed on monday for the first time a LTSP server-basic on Debian
06:55
But I cannot find a guide for the LTSP n°5?
06:56
There are available only for 4.2 version!
06:56
<ogra>
!debian
06:56
<ltspbot>
ogra: "debian" is is a GNU/Linux based operating system that makes an excellent LTSP server. You can find it at http://www.debian.org. for information about LTSP on debian see http://wiki.debian.org/LTSP
06:56
<ogra>
since most developent is done in ubuntu that might help too:
06:56
!ubuntu
06:56
<ltspbot>
ogra: "ubuntu" is a Debian based GNU/Linux distrubution that includes a Ubuntu specific version of LTSP. It can be found at http://www.ubuntulinux.org. to install ltsp on ubuntu: https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
06:57
<filorp>
yes that kind it's "too quick"
06:57
<ogra>
apart from that a fulltext search for ltsp5 should retun some docs as well on wiki.ltsp.org
06:57
look in the UbuntuLTSP folder, there is a bunch of docs
06:58
https://help.ubuntu.com/community/EdubuntuFAQ might also have some hints
07:01
<filorp>
ok I'm searching....
07:01fernando1 has joined #ltsp
07:01
<ogra>
which debian is that ?
07:01
etch or sid ?
07:01
note that etch's ltsp is pretty old (older than ubuntu edgy)
07:02
there are backports somewhere ... (should be noted on the debian page)
07:02
<filorp>
etch
07:07
I don't figured how logically ltsp works... for example, my client download a kernel from my tftp server, that kernek is named "2.6.18-4-486", so I did a research in my server's folders with "find"...but
07:07
nothing this file doesn't exist!!
07:08
where ltsp take the kernel for the clients and how to modify it?
07:08
it's a mistery for me
07:09
<ogra>
it exists in /opt/ltsp/i386/boot and in /var/lib/tftpboot/i386 ;)
07:14
<filorp>
ooo yes thank you , it's named with a prefix nbi...
07:14
<ogra>
no
07:14
thats the etherboot image
07:14
the PXE bootimage is just called vmlinuz
07:15
<filorp>
aaaah ok , maybe my client download the etherboot image?
07:16
<ogra>
only if you use etherboot :)
07:16
at least in ubuntu with the autogenerated dhcp config it defaults to automatically select etherboot or PXE depending on the client
07:17
i know debian changed stuff of that autosetup
07:17otavio has joined #ltsp
07:17
<filorp>
I use a floppy image from ROM-O-MATIC ..it is pxe or etherboot
07:17
?
07:17
<ogra>
depends what you selected when you generated it
07:18
the rom-o-matic images can emulate PXE via etherboot ...
07:18
(i think thats the defaultnowadays, but i'm not sure)
07:19
<filorp>
I selected the default one "floppy ROM bootable image"
07:19
I can try anotherone
07:21mistik1 has quit IRC
07:21
<filorp>
there is also "PXE bootstrap loader format rom image"
07:21
I try this one
07:21
<ogra>
well, you should see it saying something about starting PXE during bot somewhere

Hi! ... I set LOCALDEV = TRUE , installed and loaded the fuse module, installed the ltspfs, added the user to the fuse group ... what more I need to make my local dev available to the clients?
07:53
O.o
07:58
when the ltsp client boots it retrieve the groups and passwd information from /etc or from /opt/ltsp/i386/etc?
08:01
<ogra>
cdealer, there are no users in the client environment ... so the servers file counts indeed
08:02
<cdealer>
[ogra]:: hey ... the last time I was asking the samequestion about localdev, and worked... now after a reinstall I cant make it work again...
08:03
<ogra>
was that uuntu or debian ?
08:03
*ubuntu
08:03
<cdealer>
[ogra]:: ubuntu 7.04
08:03
<ogra>
ah, right
08:05
you have done everything from https://wiki.ubuntu.com/EnableLTSP5LocalDevices i guess
08:06
(actually that should be there already if you used the ltsp-server-standalone package)
08:07
<cdealer>
[ogra]:: its impressive how I neve found these links you sent... lol ... but I done the ltsp-server-standalone, openssh, dhcp3, ltspfs
08:09fernando1 has quit IRC
08:10
<ogra>
dhcp3-server and ltspfs are dependecies of ltsp-server-standalone ... they get installed automatically
08:10
did you fiddle with the lts.conf any further `
08:10
?
08:11
(the default lts.conf in ubuntu has LOCALDEV=True already)
08:11fernando1 has joined #ltsp
08:12
<cdealer>
[ogra]:: yeah... its all like is supposed to be... those things at the link you paste I just made and now the user are getting access to the server drivers... not his own
08:12
<ogra>
paste you lts.conf to the pastebot :)
08:12
<cdealer>
ok

08:20
<cdealer>
[ogra]:: =)
08:20
<ogra>
looks good
08:21
can you add SCREEN_07=ldm and SCREEN_02=shell to the default section and boot a client ?
08:21
thn switch wih ctrl-alt-f2 to console after booting
08:23
... then plug in your USB stick (or whatever device you test there) and check with the dmesg command if its recognized by the clients kernel
08:24
there should be messages about sda/sdb or sdc in the output ...
08:24
<cdealer>
[ogra]:: ok ... lets see...
08:27
[ogra]:: didnt boot yet... but when I take off or plug again the device it outputs a message on the booting screen
08:27
<ogra>
let it finish booting and plug it in then
08:28ogra has quit IRC
08:31
<cdealer>
ogra, ok, now when I plug the usb device it recognize and sets it to the sda1, buuut the sda1 that is mount on the client is the server disk (it start to appear after changing the user account proprerties like said on the link you first give)

08:33
<ogra>
grep sda1 /etc/fstab
08:33
des that print any output if run while the device is plugged in ?
08:33
(on the client)
08:34
(on the server side a usb device like that would be called usbdisk-sda1)
08:35
<cdealer>
yeah
08:35
<ogra>
yeah ?
08:35
you mean you got it in fstab on the client ?
08:35
<cdealer>
[ogra]:: its in /dev/sda1 /var/run/drive/usbdisk-sda1
08:35
<ogra>
good, so the client side works
08:36
check with: ps ax|grep ltspfsd
08:36
if the ltspfs daemon runs on the client
08:36
you should get one master process and one for every attached device in the processlist ... (i.e. two in your case)
08:37
<cdealer>
[ogra]:: no... only one ltspfsd -a process and the grep process itself
08:37
<ogra>
ok at least its there ...
08:38
unplug the device and log in in X ....
08:38
<cdealer>
[ogra]:: the ltspfsd must be installed direct on the server or in the chroot enviroment ?
08:38
<ogra>
only in the chroot
08:38
never ever install it on the server
08:38
that breaks
08:38
<cdealer>
[ogra]:: so there is the problem
08:38
<ogra>
well, it isnt installable
08:39
<cdealer>
[ogra]:: I will do it now on the chroot
08:39
<ogra>
ogra@laptop:~$ apt-cache show ltspfsd|grep Depends
08:39
Depends: libc6 (>= 2.5-5), libx11-6, libxau6, python (>= 2.4), ltsp-client
08:39
no !
08:39
<cdealer>
why?
08:39
<ogra>
its there already if you have seen it with ps ax
08:39
you cant install it on the server ...
08:39
it needs ltsp-client installed which is not installable on normal systems
08:40
<cdealer>
but I tryied on the server and receive some erros like saying it wont be installed because depends of the ltsp-client... but I installed the ltspfs
08:40
<ogra>
right
08:40
ltspfs is the stuff you need on the server side
08:40
<cdealer>
Ah .. ok ...
08:40
<ogra>
probably do a: sudo apt-get remove --purge ltspfsd
08:40
to make sure there is no cruft left from your attempt
08:41
(on the server)
08:41
<cdealer>
its freeing 130kb
08:42
<ogra>
good
08:42
<cdealer>
must I try again with the usb stick ?
08:42
<ogra>
yes
08:42
see what happens
08:42
<cdealer>
I will reboot the thin client
08:42
<ogra>
i dont think thats needed
08:43
your client side seemed proper
08:43
<cdealer>
too late... hehe ...one sec it will be back
08:44
<ogra>
rather reboot the server to make sure udev was restarted properly and all the ltsp client rules are gone
08:44
<cdealer>
ok
08:47
[ogra]:: !! worked now =D
08:47
<ogra>
:)
08:47
good
08:48
<cdealer>
the more funny about this is that before I tryed to install the ltspfsd it wasnt working .... but must be the step in the guide you passed about allowing the user to mount fuse devices
08:48
thank dude... you are the ltsp man hehe
08:50
<ogra>
well, i wrote a lot of it ;)
09:03Guaraldo has joined #ltsp
09:04
<cdealer>
[ogra]:: let me hook you in another question (i think this is a bit more dificult)... some clients will need to use skype (or any voip program that works on ltsp) after searching a litle I found a guide about using pulseaudio to make this available, but I noticed that in the installation it already install pulse-esd-compat but still get an audio error when trying to use skype (xmms, rhythmbox, etc, works good)
09:05
<ogra>
talk to MrMoo about that, he wrote the guide
09:05
he is in some US timezone i think
09:05
so might come around soon
09:17

takes about 2secs to generate the file now ...
09:49
<jammcq>
wow
09:50
anybody seen scotty ?
09:50

and it finally supports X_MODE ;)
09:50

well, i just use what Xorg -configure gives me and sed through it
09:51
<jammcq>
nice
09:51
<ogra>
i think i'll just replace the Xorg binary with it if CONFIGURE_X is true
09:52
and have a call for the real binary in the end ...
09:52
(of the script)
09:52
so we ca ame sure it works on all setups ...
09:52
*can make
09:52
<jammcq>
so the default will be auto-configure ?
09:52
<ogra>
no
09:52
unless it proves itself to be better
09:52
<jammcq>
oh
09:53
<ogra>
no config is still the fastest :)
09:53
<jammcq>
that's what I meant
09:53
the default will be no config file at all
09:53
?
09:53
<ogra>
Xorg -configure needs to start the server once ... so we will have a flashing screen
09:53
not sure yet, i have to see how it wrks out ..
09:54

ah

09:56

there are also some cards that seem to not free the framebuffer without config file ... (i.e. the sis driver) so it doesnt restart properly ...
09:57

09:57
<cdealer>
[ogra]:: where do I change the background image of the client login screen ??
09:57
<McDutchie>
hi all, i am trying to get two LTSP 4.2 terminals to work with two new AG Neovo K-A19 widescreen TFT monitors, and I can't for the life of me get the proper resolution of 1440x900 to work... when I specify the mode as simply "1440x900", /tmp/mnt/xorg.log says "no mode by that name" and when I give it a full modeline calculated with `amlc', it says "not using mode 1440x900 because there is no clock available". help! anyone any ideas?
09:58
<jammcq>
McDutchie: you prolly also need to provide X_HORZSYNC and X_VERTREFRESH
09:59
<McDutchie>
jammcq: yes, I have done that, according to the manual that is 31.47 - 80.0 and 50.0 - 75.0 respectively
09:59
<jammcq>
hmm
09:59
<ogra>
cdealer, there is no easy way atm ... look where /opt/ltsp/i386/etc/alternatives/ldm-theme points to (note that will appear broken outside the chroot) and to replace bg.png in there
09:59
<McDutchie>
it still won't take at all. :(
09:59
<jammcq>
set SCREEN_01 = shell
09:59
then at the shell prompt, run: startx
09:59
then go look in /tmp for the Xorg log file
09:59
<McDutchie>
i have SCREEN_03 = shell already so I can access the log file right now
10:00
<jammcq>
ok
10:00
<ogra>
McDutchie, you dont happen t use an intel graphics card with that ?
10:00
<jammcq>
that should tell you why it's not liking things
10:00
<McDutchie>
ogra: no, it's a VIA VT8378 [S3 UniChrome]
10:00
<jammcq>
oh
10:01
<ogra>
chack if its using the via driver
10:01
*check
10:01
<jammcq>
via's can be problematic
10:01
<McDutchie>
jammcq: yes, it does, it says "no mode by that name" or if I give a modeline, "no clock available for that mode"\
10:01
<ogra>
vesa might not go above 1024x768
10:01
<McDutchie>
ogra: oh, it decided to give me 1600x1200 (too high for that monitor)... so i doubt that's it :)
10:01
<ogra>
ah
10:02
<McDutchie>
ogra: yes, it's using the via driver (just checked)
10:02
<jammcq>
how did you come up with the modeline ?
10:03
<McDutchie>
jammcq: calculated with amlc ("another modeline calculator"), see http://amlc.berlios.de
10:03
jammcq: i don't know how else to make them, it's greek to me :/
10:03
<jammcq>
can you boot a live cd, like ubuntu or knoppix ?
10:03
<McDutchie>
jammcq: yes, can boot knoppix
10:03
<jammcq>
well, see how that configures it
10:04
<McDutchie>
jammcq: i don't think that detects it either but i'll try and make sure.
10:04
<jammcq>
well, if you can't get it working with knoppix or ubuntu, it's gonna be really hard to get it working with ltsp
10:05
<ogra>
if you get it working with an ubuntu liveCD its sure that ltsp5 would work at least :)

jammcq: darn :(
10:05
ogra: unfortunately ltsp5 won't work on our slackware server
10:05
<ogra>
McDutchie, why ?
10:05
there are tarballs
10:06
<McDutchie>
ogra: oh, i thought ltsp5 needed to be integrated in the distro
10:06
<ogra>
it does
10:06
but we made tarballs of the client chroots ...
10:06
you can set up the server side manually and just use these for your nfsroot
10:06jsgotangco has quit IRC
10:06
<ogra>
the client env will then be ubuntu ...
10:07
<jammcq>
before you worry aabout that, get it working with a live cd
10:07
<ogra>
(or debian if you choose that(
10:07
yeah
10:07
<filorp>
hi all
10:07
<jammcq>
and IF you can get it working with a ubuntu live cd, you can steal the modeline and use it in LTSP-4.2 if you want, OR, you can install the ltsp-5 tarball on slackware
10:07
<ogra>
in ubuntu ltsp5 uses the exactly same autodetection for X the liveCD uses
10:07
<jammcq>
hey filorp
10:07
<ogra>
so if that works ltsp5 will d as well
10:08
s/d/do
10:08
<filorp>
I have kernel panic..
10:08
<McDutchie>
jammcq: does it need to be a ubuntu live cd or is knoppix (5.0.1) good enough?
10:08
<filorp>
I read few post on google about my error..
10:08
<jammcq>
McDutchie: whichever one works for you. if knoppix doesn't work, try ubuntu
10:08
<McDutchie>
jammcq: ok. i may have some downloading to do, then.
10:08
<jammcq>
filorp: you need to tell us more about your panic message
10:09
<filorp>
ok
10:09
<McDutchie>
jammcq: how do i 'steal the modeline'?
10:09
<jammcq>
look at the generated Xorg.conf file and find the modeline
10:09
copy it into your lts.conf file
10:09
<McDutchie>
jammcq: what if it's just a resolution without a modeline?
10:09
<jammcq>
or take the entire xorg.conf file and use that
10:10
McDutchie: there's likely a complete modeline in that file
10:10
<filorp>
look my output on boot:
10:10
after many lines:
10:10
<McDutchie>
jammcq: ok. going to try that. i'll be back in a bit. thanks so far

<ogra>
filorp, what distro ?
10:11
<filorp>
ipconfig: etho: SIOCGIFINDEX
10:12
A DEBIAN BASED distro
10:12
<ogra>
filorp, which one exactly ?
10:13
that looks very much like your network card isnt suported by the kernel tats used
10:13
<filorp>
Dreamlinux , using debian repository
10:13
no such device
10:13
<ogra>
whic repo does it use ? sid(unstable) or etch (stable) ?
10:13
<filorp>
ipconfig: no devices to configure
10:13
<ogra>
and which kernel
10:14
<filorp>
init: : 152: can't open /tmp/net-eth0.conf
10:14

yeah, you are missing a driver for your network card

what kernel does that thing use ?
10:14
ls -l /opt/ltsp/i386/boot/vmlinuz
10:14
<McDutchie>
jammcq: well, i'm in ubuntu now, it just gives me the standard 1280x1024, so that's pretty useless... there are modelines in xorg.conf though, as you said.

10:15
<McDutchie>
jammcq: exactly
10:15
<ogra>
filorp, do you know what kind of NIC is in the client ?
10:15
<jammcq>
McDutchie: i'm guessing your monitor is lying about its DDC output
10:16
<McDutchie>
jammcq: how would i override that?
10:16
<ogra>
jammcq, or ddcprobe is to old ;)
10:16
<filorp>
off course is 3com - 3c509b
10:16
isa
10:16
<ogra>
ouch
10:16
isa is very tricky
10:16
<jammcq>
McDutchie: you can override it with your own modeline. problem is, you don't know exactly what values to use
10:16
McDutchie: try ubuntu, see if that works any better
10:16
<ogra>
filorp, do you have a PCI card you could put in there ?
10:17
filorp, ISA cards will cause you *lots* of work to get going properly
10:17
<McDutchie>
jammcq: right. will do. that'll take a long time to download at 80k/sec though, so ttyl (and thanks for your help and patience so far!)
10:17
<jammcq>
ogra: does ltsp-5 have any support for isa network cards?
10:17
<filorp>
I'm new to ltsp, to recompile the ltsp kernel I have to chroot?
10:17
<jammcq>
McDutchie: good luck
10:17
<ogra>
jammcq, well, you could poke it into the chroot indeed
10:17mikkel has joined #ltsp
10:17
<jammcq>
ogra: yeah, but any support via dhcpd or pxe settings?
10:17
<ogra>
jammcq, beyond that you could use the old style dhcp options ...
10:18
<jammcq>
that still works?
10:18
<filorp>
mmmm...
10:18
<jammcq>
NIC=3c509 ?
10:18
<ogra>
sure why shouldnt it ?
10:18
<jammcq>
because your initramfs is so different from mine
10:18
<ogra>
at least i'D expect it to
10:18
but still ISA will cause endless pain ...
10:18
<jammcq>
my initramfs looks for NIC and uses that, instead of auto detecting the nic
10:18
<ogra>
if there is any way to avoid it i'D do that
10:19
hmm
10:19* jammcq hasn't even seen an ISA nic in a couple of years
10:20
<ogra>
hmm
10:20
<filorp>
I have a lot of this kind of isa card :)
10:20
<ogra>
grep -R NIC /usr/share/initramfs-tools/* doesnt reveal anything useful :/
10:21
<filorp>
I try one moment
10:21
<ogra>
but you could put it into /etc/initramfs-tools/modules and regenrate the initramfs
10:21
indeed that works only for one client :/
10:22
or one kind of setup rather ...
10:22
<filorp>
no output
10:22
<ogra>
filorp, ??
10:22
<filorp>
yes
10:22* ogra wonders what filorp is talking about
10:23
<filorp>
I have to add this module in some way
10:23McDutchie has quit IRC
10:23Avatara has joined #ltsp
10:23vanya has quit IRC
10:24
<ogra>
well see above, you could add the module line to /etc/initramfs-tools/modules with all options for IRQ and PORT ... regeerate the initramfs for the clients and then you need to make sure the card setup is the same on *all* clients
10:24
its a lot of work
10:24
<filorp>
this apply to all client?
10:25
<ogra>
and no guarantee that works ...
10:25
yes, if you add it to the module file thats used in initramfs it applies to all clients and will break on all that have a different setup with the same card
10:25
<filorp>
can I use another kernel recompiled?
10:25
<ogra>
that wont help much ...
10:26
you need to set the irq and port settings statically in any case ... if one client doesnt match that it will break
10:26
so it wont matter if you compile your own kernel or use the module way i described above ... the outcome is the same
10:27
the initramfs way is the easier and fater one
10:27
*faster
10:27
chroot /opt/ltsp/i386 vi /etc/initramfs-tools/modules
10:27
add the module line with all the options
10:27
chroot /opt/ltsp/i386 update-initramfs -u
10:28
<filorp>
how to regenerate the initramfs
10:28
?
10:28
<ogra>
ltsp-update-kernels
10:28
thats all you need
10:28
three commands and one file to edit :)

I have some general questions, so might not be in the scope of LTSP, but they came up because of its usage. Just random questions/issues I want to ask about if that is ok
10:58jvin248 has quit IRC
10:59
<Shane-S>
I am sure wireless booting is possible if the system recognizes the network, so it presents an issue of security, anyone know if modern devices can see WLAN networks and ask for security credentials. I guess it can be open, and when the OS is loaded your authenticate then.
11:00
<ogra>
Shane-S, that needs a good bunch or initramfs hacking
11:00
s/or/of/
11:01
<Shane-S>
Next one I had, is lets say you have a max node load of 30 TC per server, would your implement a network re-routing, or perhaps load balancing between the servers?
11:01
<ogra>
initramfs needs all the wireless tools ...
11:01
it needs to respect a kernel commandline option that hands over essid and key for the WLAN
11:01
then it could work
11:01
<Shane-S>
ahh ok thanks, wasn't sure, but would be damn cool to tell people, yep come out on the grassy knoll and load Fedora or Ubuntu with out software :D
11:02
<ogra>
oh, and indeed you will need kernel and initramfs locally somewhere, there is no such thing like PXE or etherboot for WLAN
11:02
so it will only function if you boot from USB stick or CD
11:03
(current kernels wont fit on floppies)
11:03
<Shane-S>
hmmm ok, that sounds resonable, as allowing that sort of thing unsecured wirelessly would present a massive security risk, so a USB key boot option isnt bad
11:04
didnt think of that
11:04
good project for me to work on then if the LAN base takes off
11:04
<ogra>
if i have soe time left this release cycle (which is very unlikely), i will work on it
11:04
<Shane-S>
I could push for a notebook thin client purchase or donation and try and get that working
11:05
<ogra>
its on my TODO since quite some time but has a pretty low prio :)
11:05
<Shane-S>
no major rush on my part, the concept popped in my head are 3:00 AM this morning
11:06
was like wow how awsome it would be to walk up to work and you system netboot wirelessly the OS the business/school/etc. wanted you to have
11:06
but heck, a USB is that can do that is cool
11:06
<ogra>
if you use ubuntu and have slight scripting skills, look at the scripts and nooks under /usr/share/initramfs-tools/
11:07
<Shane-S>
hey visitor, here is your hall pass, security card, ohh yeah, we don't know what is on your system, so here OS USB key
11:07
<ogra>
it shouldnt be to hard to come up with a wlan bootscript if you roughly know what you do
11:07
<Shane-S>
im am a newbie too it, K12LTSP introduced it me
11:07jvin248 has joined #ltsp
11:08
<Shane-S>
but that does exactly what I invisioned, NO os, the server loads it all
11:08
the closest thing I could find Windows wise was embeddedXP
11:08
<ogra>
i think there are way to netboot win ....
11:08
<Shane-S>
and now with Dell shipping Ubuntu, I think I have even more backing to start introducing Linux
11:08
<ogra>
*ways
11:09
commercial ones likely ...
11:09
<Shane-S>
I am sure there are, but in my searching nothing was clear or simple...or free
11:09
<ogra>
yeah, free might be the prob :)
11:09
<Shane-S>
Citrix I know can do it, and all th Terminal Server stuff I loaded you need the RDP client
11:10
and I have old system that can't even run anything above 98
11:10
even Ubuntu is a stretch, so gettign 128MB ram is easy enough, and making a TC works
11:11
ohh anyone tried LTSP in VMWare, or Virtual Box?
11:11
<ogra>
thats how i develop if i travel :)
11:11
(VirtualBox)
11:11
<Shane-S>
ok, but what I mean is Server (VMed) pushing to clients
11:11
<ogra>
we also ship a quemu bootscript in ltsp5
11:11
*qemu
11:12
ah, well, thas possible as well, i personally only use it as test/dev client on my latop
11:12
<Shane-S>
what is that? sorry totally new to this booting and virtualization
11:13
<ogra>
qemu is a free virtual machine
11:13
<Shane-S>
I only ask, because I am not sure how much server I can afford to start, and VMware gives me the flexibility to instantly scales other servers down
11:14
<ogra>
we run a vmware based LTSP server in the ubuntu support center all workplaces are thin clients ... so it seems to work (i havet seen that setup personally yet)
11:15
<filorp>
well done ogra! I added the module for 3c509 card as you told me but without options and no more kernel panic. thank you but now ....
11:15
<ogra>
cool !
11:15
<filorp>
I have another error
11:15
<ogra>
tell us :)
11:16
<Shane-S>
ahh ok...hmm that Qemu, could LTSP boot that and then it load a virtual drive/os off the LTSP server to load say...Windows?
11:16
<filorp>
there is a kind of loop cicle
11:16
ipconfig: eth0 complete
11:16
begin running /scripts/nfs-premount..
11:16
done.
11:17
<ogra>
then you should see a bunch of IP data ...
11:17
and then it should moount its nfs root
11:17
*mount
11:17
<filorp>
begin: retrying nfs mount..
11:17
yes it took the ip settings well.
11:17
then
11:18
restart the same message again and again and again
11:18
<ogra>
Shane-S, qemu is a lot slower than vmware ... the script we ship is only to run a virtual client
11:18
<filorp>
ipconfig: eth0 ...etc etc
11:18
<ogra>
no error message ?
11:18
<filorp>
no is a loop
11:19
<ogra>
there should be an nfs error or something
11:19
<filorp>
never stop
11:19
<ogra>
well the error that causes the loop should show up there anywhere
11:19
<filorp>
after retrying nfs mount ...
11:19
<ogra>
its likely nfs related ...
11:19
in the IP data there should be a line for rootserver
11:19
does the IP match your server ?
11:20
<Shane-S>
orga: Im confused then...a ThinC is essentially just sent a kernal and load it up so it can communicate....what does the purpose of virtual client server?
11:20
<filorp>
suddenly print again the ip settings.. and same messages related to nfs
11:20
<Shane-S>
s/server/serve/
11:20
<filorp>
all the ip matches my network
11:20
<ogra>
filorp, what are the values for rootserver and rootpath ?
11:21
they should appear there
11:21
<filorp>
yes they appear
11:21
one moment
11:22
<ogra>
Shane-S, you can run different server in different vm's on one machine and have a secure environment thats only containing whats needed for one purpose
11:23
indeed the extra VM eats ressources
11:23
<cdealer>
[ogra]:: i have changed the background.png file that are inside the /opt/ltsp/i386/etc/alternatives/ldm-theme for another file that i just made... someelse to do ? No change to the login background yet

<ogra>
cdealer, bg.png ;) not background.png
11:23
oh, no, wait
11:23
<cdealer>
[ogra]:: ok... but inside was a background.png...
11:24
<ogra>
i only have gutsy here ... thats changed a lot
11:24
<cdealer>
Hmmm vagrantc dont know anything about it ?
11:25
lets see... there are a README file inside
11:25
<ogra>
cdealer, vagrant doesnt touch ugly gui code :)
11:25
<filorp>
rootpath was: 192.168.13.30:/opt/ltsp/i386
11:25
<Shane-S>
orgra: I will let it go...not wrapping my brain around the need of the "virtual client" as each virtual server could still run LTSP, unless for saving those resouce you mean you use the Virtual Client boot so you have one LTSP server and that booter directs them to the proper Virtual Machine on the Virtualized server
11:25
<cdealer>
[ogra]:: hehehe ok
11:25
<ogra>
filorp, try to change that to /opt/ltsp/i386 in your dhcpd.conf
11:26
there were older versions of initramfs with a bug that broke if you have ip and colon in the rootpath, seems your distro uses such a version
11:27
it was fixed some time ago in debian sid ... and today in ubuntu
11:27
vagrantc, do you remember the version number in debian ?
11:28
<filorp>
I think I need to specify that ip, because my dhcp server is another linux pc in my network
11:29
<ogra>
do you use PXE or etherboot ?
11:29
for PXE i have a workaround ...
11:29
<filorp>
I'm using PXE now
11:30
<ogra>
add nfsroot="192.168.13.30:/opt/ltsp/i386" to your PXE config
11:30
usually thats in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
11:31
<Shane-S>
orge, I read somewhere PXE is newer the Bootp,and should be used over it, is etherboot something else? Is that untrue, was just some tech's blog
11:31
<ogra>
append it to he lie in there
11:31
Shane-S, thats true ...
11:31
<Shane-S>
sorry s/orge/orga/
11:31
<ogra>
most newer network cards can do PXE
11:31zodman has joined #ltsp
11:31
<Shane-S>
LTSP supports both though right?
11:31
<ogra>
right
11:32
<Shane-S>
ok, cause I have older systems, like I said K12LTSP was my into, and it just works on an old server out of the box
11:36
<filorp>
ogra , I added that line in my PXE config...
11:37
now , should I restart ltsp in someway?
11:37
maybe not
11:37
<ogra>
just the client
11:37
<filorp>
ok , I run
11:37
;)
11:40
<vagrantc>
initramfs-tools 0.88 fixed the bug with specifying IP in the root-path argument
11:41

11:42* vagrantc smiles at the new basqe translation

damned, that remonds me, i need to add the gettext stuff to ldm ...
11:42
i already started it, but am not done yet ...
11:42

indeed!
11:43

i want at least *some* translations in gutsy
11:43
for the gui
11:44
<vagrantc>
oooh. vietnamese
11:44
<cdealer>
[ogra]:: Welll... chaging things inside ldm-theme doesnt seen to make any difference... but inside there are the file that are being displayed at the login prompt... =//
11:44

cdealer, are yu sure you edit in the right directory ?
11:44
cdealer, which logo do you see on the current ldm screen ?
11:45
<cdealer>
[ogra]:: the UBUNTU title that are in the login screen ... I changed it, I change the colors file to other color and nothing happens
11:46
<ogra>
use /opt/ltsp/i386/usr/share/ldm/themes/ubuntu as the dir and see if that works then
11:47
<cdealer>
[ogra]:: the files inside the ldm-theme folder (that point to /usr/share/ldm/themes/ubuntu)
11:47
[ogra]:: I will give a try
11:47Shane-S_ has joined #LTSP
11:47
<ogra>
also how do you test the new theme ? just restarting X ? that might not suffice ...
11:48
might be necessary to reboot the client
11:48
<cdealer>
[ogra]:: I have reboot both server and client... but I think what you said will work nice
11:48
<ogra>
(its ages ago that i made the themes, cant remember)
11:48
and gutsy has a completely new and different ldm ...
11:49
<cdealer>
[ogra]:: I was editing the /usr/share/ldm/themes/ubuntu but is like you said its inside /opt/ltsp/i386/usr/share/ldm/themes/ubuntu
11:49
<ogra>
ah, right, indeed
11:49
we have galician translations ? wow
11:50
<vagrantc>
ctrl-alt-backspace at least works with the python ldm to reload a theme
11:50
<cdealer>
[vagrantc]:: yeah.. worked here too
11:50

ooooh! i have real hardware to test on!
11:50

vagrantc, for ldm2 thats currentl rather a matter of luck *G*
11:51

i gotta test this newfandangled ldm
11:51
<ogra>
yeah
11:51
i'm eager to test the new stuff sbalneav wrote with the stdin/stdout controlled greeter
11:52
but he's not done yet its nothing i can pull in
11:52
so i'm waiting for his go ...
11:52
but the current one in ubuntu is already very impressing
11:53
vagrantc, yu gotta test nbd/squash/unionfs ;)
11:54* ogra goes to find some dinner
11:54

yeah, i've got lots of testing to do.
12:03

12:16
vagrantc, there is a way through fd 9 and some fifos to get the output of ltsp-build-cient to the installer ui ...
12:17
but its a very complicated redirection you need for that

[ogra]:: ok ... other problem. Im trying to make the webcam to work. Localy its working already. If I try to test using camorama or camstream on the client I cant connect to the /dev/video0 device... but when I go to the shell and make a od -x /dev/video0 I have an output (showing that the device is receiving the webcam)... how do I make this device to work ?

[ogra]:: was to bad the question ? lol
12:34
<jvin248>
How to specify the root-server? I have clients booting thorugh pxe but are failing nfsmount because they are grabbing the router as rootserver rather than the ltsp server.
12:35
I have a mixed dhcp (modem provides it unless ltsp server is on and then it gives "authoritative" command).
12:36
I tried the suggestion for <filorp> but didn't get any farther. Any lines like "option root-server x.x.x.x;" in dhcpd3.conf to do this?
12:36
ltsp server has a static IP
12:38
err.. /etc/ltsp/dhcpd.conf file (running ltsp on kubuntu 6.10).
12:41
<filorp>
what kind of router is your primary dhcp server jvin248?

I have a problem that I'm hoping that someone can help me with. I'm using LTSP 3 and I'm trying to configure an IBM ThinkCentre 8185 as a client. On powering it up it gets as far as: "loading 192.168.2.100:/lts/vmliuz-2.4.19-ltsp-1 .." and then halts.
14:19
I have 11 other clients that work fine. No other ThinkCentres though.

This is for a personal folding@home farm. I don't use it for anything other than that. I got it working a while ago and have been generaly hands-off so I don't risk fubaring it. I haven't been keeping up with releases.

The server CPU is less than half the speed of the one in the ThinkCentre. Does anyone know if a slow server and fast client is a problomatic combination?

18:12

so far, within 24 hours of posting a request for translations for ltsp in debian, i've gotten translations for portuguese, galician, basque, and vietnamese ... and an updated german translation
18:12

nice
18:12
that must be a rewarding felling
18:13

unfortunately, it's not a translation of the other parts of the system, just the debconf questions

jvin248: you need to use update-alternatives to redirect the "default" symlink in that directory
22:53
jvin248: man update-alternatives
22:53
you'll have to update-alternatives --install ... .as well as update-alternatives --config
22:54
jvin248: each of the directories in /opt/ltsp/i386/usr/share/ldm/themes is a theme ...
22:55
jvin248: and /opt/ltsp/i386/usr/share/ldm/themes/default is a symbolic link that points to which directory to use ...
