muppis, sir i got this and i am using it right now : https://fedorahosted.org/k12linux/wiki/RHEL5Server
00:24
is this perfect??
00:27
<muppis>

Something odd.. I tried to install xbmc my wife's laptop. Complained about missing OpenGL support, so tried to install closed source ATI's with no joy. Yesterday I booted to LTSP to just test my dnsmasq config. It booted with my htpc/xbmc image and xbmc was launched nicely.
02:05
<Appiah>
so xbmc launched one driver
02:05
and ltsp another..
02:06
check Xorg log for which one and check version on xbmc vs your ltsp
02:07
<muppis>
Why xbmc could have it own drivers for gpu?
02:09dobber has joined #ltsp
02:11
<Appiah>
"own" ?
02:12
there are like 3-4 different drivers for ATI cards..
02:13
ati , radeon , fglrx
02:13
<muppis>
I think it was fglrx as only which 'supports' Radeon 200M
02:13
As didn't work at all.
02:14
<Appiah>
so both are running the same driver and the same version?
02:15
<muppis>
In LTSP I haven't installed any ATI related.
02:15
<Appiah>
is radeon and ati not included by default?
02:16
(in your dist)
02:16
<muppis>
xserver-xorg-video-radeon is installed by default, even on this machine.
02:17
<Appiah>
and which one does X start with?
02:18
<muppis>
No clue. Not at home right now and I don't think wife got laptop turned on right now.
02:18
And my homeserver doesn't respond to ssh.
02:20
Sure thing.. DDNS got wrong IP.
02:22
But what could be problem? I installed nvidia-current to chroot. Client hangs after init-bottom -script.
02:22
Or where I should start looking at.
02:22
<Appiah>
nvidia? :)
02:22
<muppis>
For my HTPC. :P
02:22
<Appiah>
:D
02:23
hmm..
02:24
a recent card? some nvidia cards cant runnt current so you have to run nvidia-185 something
02:24
-nt
02:24
<muppis>
8400gt, if I remember correctly.
02:26
Had to try that one then.

hello guys n gals
05:21
a new ltsp user needing some networking config advice
05:21
<muppis>
Tell us.
05:21
<tech_dvo>
thanks! -- oky
05:22
first off -- client booting is slow -- at 26KB/s then stopped/hang when 'done'
05:23
i'm using ubuntu 10.10 amd64
05:23
clients are i386 machines
05:24
network wiring setup : https://help.ubuntu.com/community/UbuntuLTSP/LTSPWiring choice number 2
05:24
I am not sure about my /etc/ltsp/dhcpd.conf though
05:25
i'm guessing it's working because the booting works -- at the beginning though at a slow slow pace
05:27
<muppis>
Clients can't access to internet?
05:28
<tech_dvo>
not even there yet -- because the thin clients hangs even before a login screen is presented
05:30
<muppis>
Remove words quiet and splash from /var/lib/tftboot/ltsp/i386/pxelinux.cf/default and then try boot client.
05:30
/var/lib/tftboot/ltsp/i386/pxelinux.cfg/default should be
05:33
<tech_dvo>
okay

still have the same problem
07:06
thin client hangs
07:07
<muppis>
Does it show any errors there?
07:07
<tech_dvo>
no errors
07:07
just .......then the word done in bold letters
07:10bobby_C has quit IRC
07:11
<muppis>
What it says before those dots?
07:11
<tech_dvo>
it finds the dhcp server then
07:11
says what ip address is assigned
07:11
then something with i386 file being copied?
07:12
I cannot exactly say because the message has scrolled way up because of the dots
07:16zz_evil_root is now known as evil_root
07:17
<muppis>
Strange.
07:17
<alkisg>
tech_dvo: distro/version?
07:19
<tech_dvo>
ubuntu 10.10
07:19
<alkisg>
tech_dvo: sudo gedit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default, remove "quiet splash" from there, and reboot the client
07:20
Also, what arch is your server and what your chroot? i386?
07:20
<tech_dvo>
that's what muppis made me do
07:20
server amd64 thin client i386
07:20
<alkisg>
Ah, I didn't see any previous chat, I thought you just joined the channel.
07:21
<tech_dvo>
maybe something wrong with my thin client boot?
07:21
I am using gPXE
07:21
but I'm not sure if I made it right
07:22
i managed to boot a netbook with a boot rom -- I think it worked because it's displaying the login screen now
07:22
<alkisg>
So, only the gpxe client is having problems? Which gpxe version?
07:24
<tech_dvo>
is this right: eb-5.4.4-rtl8139.iso?
07:24
<alkisg>
Yes, it's right, and no, it isn't gpxe :D
07:25
It's an old, unsupported version of etherboot
07:25
Replace your disk, use a recent gpxe version
07:25
!gpxe
07:25
<ltspbot>
alkisg: "gpxe" :: the successor to etherboot (http://etherboot.org). To download bootable floppy, cd, usb, kernel etc images, visit http://rom-o-matic.net/
07:26
<tech_dvo>
ok -- i'll do that -- i'm excited already because I just made my netbook boot over ltsp
07:29
by the way -- why do I have to remove those things?
07:30
<robehend1>
by removing quiet splash, it allows us to see any errors that are made
07:32
<alkisg>
tech_dvo: your problem is that you're using etherboot, which loads nbi.img, and that fails (known bug)
07:32
So don't change pxelinux.cfg/default, it doesn't make any difference anyway if you're using etherbot
07:32mrcarrot has joined #ltsp
07:32
<alkisg>
When you switch to gpxe it will just work
07:33
<tech_dvo>
ok, I'll try making a cd
07:33
<mrcarrot>
i am not at any ltsp environment, but i want to check if anyone knows if ldm is reading .xsession
07:34
<alkisg>
tech_dvo: Or floppy. Or usb stick. Or put it in the hard disk, if it has one.
07:34
<mrcarrot>
or is it at all possible to put for one user another wm, that he would have in his home directory
07:34
<tech_dvo>
i don't know how to put it in hard disk since the hdd has windows in it
07:34
<alkisg>
tech_dvo: We've made an "ltsp-loader.exe" that puts gpxe to the windows boot manager. Which windows version?
07:35
<tech_dvo>
windows xp pro
07:36
<alkisg>
Here's the exe: http://ts.ts.sch.gr/docs/docs-software-support/docs-software-ypepth/doc_download/327-ltsp-loader
07:36
...and here's the relevant bug description for debian win32-loader, so that they include it upstream in newer versions:
07:36
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=607417
07:37
You just run the .exe and it puts gpxe to the windows boot loader, as simple as that. If you don't want it later you can uninstall it as usual.
07:38
<tech_dvo>
does that mean I can choose windows xp or gpxe to run when powering the computer?
07:38
<alkisg>
Right
07:38
<tech_dvo>
that's pretty convenient! I'll try that, thanks!
07:39
<alkisg>
mrcarrot: I think, but I'm not sure, that ldm reads ~/.dmrc
07:39
<tech_dvo>
what do I do with the bug description?
07:39
<alkisg>
Nothing, it's just some extra info if you want to read it
07:39
You don't need to, though
07:40
<tech_dvo>
:) I'm guessing I won't --
07:40evil_root is now known as zz_evil_root
07:41
<mrcarrot>
okay, thanks. i will check it out
07:41
<cyberorg>
mrcarrot, alkisg yes you can use .dmrc
07:42
<robehend1>
alkisg: tried out the new Virtualbox version yet?
07:42
<alkisg>
robehend1: yup, it's fine, I can't wait until it comes to debian/ubuntu
07:43
<tech_dvo>
alkisg: is it in english version?
07:43
<robehend1>
alkisg: you use the OSE or the Oracle one.
07:43
<alkisg>
tech_dvo: multilingual, default english, but we *might* have left some greek-only text there. You just need to press "next" though...
07:43
robehend1: there won't be an -ose/oracle distinction for vbox 4
07:44
There will be 1 single opensource version + the proprietary "additions"
07:44
<robehend1>
classic Oracle.
07:44
<alkisg>
expansion pack how the call them
07:44
<robehend1>
bet they make USB support an addition
07:44
<alkisg>
Yup
07:44
<robehend1>
eh well, it still good for basic things
07:44
<alkisg>
But still that's much better than how sun did it
07:44
<robehend1>
agreed
07:45
<alkisg>
And I also liked the new folder organization scheme, I converted all my old VMs to it
07:45
<robehend1>
how'd it change?
07:45
<alkisg>
Instead of having ~/.virtualbox/disks / vms etc, you have ~/Documents or something/Virtualbox/VM1, VM2
07:46
I.e. organized per VM, not per "disk / snapsnot / xml etc"
07:46
<robehend1>
oh t hank goodness. finding the right disk before was never fun
07:47* alkisg wants to try out the windows version of vbox, to see if he can prepare an "ltsp vbox appliance" for labs with windows servers...
07:47
<robehend1>
what you mean, ltsp_vbox appliance?
07:47
<alkisg>
A whole ubuntu/ltsp/fat chroot installation in a VM,
07:47
<robehend1>
oh..
07:48
<alkisg>
so that teachers with windows labs can just download the VM + install vbox, and have an LTSP lab ready
07:48
<robehend1>
thats how i originally setup my setup
07:48
had the Ubuntu LTSP box sitting in VBox, and thats how clients booted.
07:48
<alkisg>
No wubi or partitioning involved. They work with that for a year, and when they're ready they can then switch to the normal setup
07:49elias_a_ is now known as elias_a
07:49
<robehend1>
alkisg: i think i have some notes from when i did something like that, actually, let me see what i can dig out after this faculty meeting
07:53
<alkisg>
Nah I'm not concerned about ports etc, I'm sure all that can be managed. I'm more concerned about networking / flow control problems
07:58
<tech_dvo>
alkisg: the exe file operated well but I'm only at starting ltsp client..... then nothing
07:59shawnp0wers has joined #ltsp
07:59
<alkisg>
tech_dvo: "starting ltsp client"? Do you mean that the kernel booted, you saw the ubuntu logo etc?
08:00
<tech_dvo>
no logo
08:00
the cd iso works, though
08:00
<alkisg>
Did you remove "quiet splash"? If yes, that's why you didn't see any logo.
08:01
I don't understand at what point you're having a problem.
08:03
<tech_dvo>
Begin: running scripts /init-bottom.... done
08:04
<alkisg>
That means that the kernel and initrd were loaded
08:05
gpxe only fetches the kernel. So if you say that it works from the cd iso and not from the hard disk, I don't understand how that's possible.
08:08
<tech_dvo>
the cd works on another client same model as the one with the exe
08:09
<hahlo>
does fatclient use swap, and if so where is the fatclients swap?
08:09
<tech_dvo>
i tried the cd with the exe installed -- it still hangs
08:09
so i think the cpu is suspect
08:09
<alkisg>
tech_dvo: Let's not compare different clients. The issue there may be your network card module.
08:09
tech_dvo: remove "quiet splash" and paste here the last lines that you see, 3-4 of them.
08:10
hahlo: fat clients, like thin clients, use swap if you tell them to
08:10
NBD_SWAP, USE_LOCAL_SWAP etc, lots of options

Maybe a graphics card module problem then
08:17
Try putting SCREEN_07=shell in lts.conf
08:17
..and if you get a shell there, run: ltspci -nn -k | grep -A 2 VGA
08:17
bbl
08:17
<tech_dvo>
what's bbl?
08:18
where is lts.conf?

08:22
you'll have to make it, if you've never used it
08:24
<tech_dvo>
i'll look into it
08:32
I have a syntax error lts.conf line 1
08:32
<robehend1>
did you put [Default] there?
08:32
it needs one
08:32
<tech_dvo>
no -- where 1st line?
08:32
<robehend1>
yep, first line of lts.conf HAS to be [Default]
08:32
regardless of what your doing with it

08:51
I'm finally running some thin clients --
08:56
What if I have different types of thin clients?
08:56
some works with vesa and others don't?
09:00
<robehend1>
then, you need to setup different drivers for each one, and show that in the chroot
09:01
good example would be https://help.ubuntu.com/community/UbuntuLTSP/AtomIon
09:05
<tech_dvo>
robehend1: do I have to set up user names for each student?
09:05
<robehend1>
depends on how you want them to login
09:06
<tech_dvo>
can I just let one class use 1 account at the same time?
09:06
<robehend1>
i'd recommend it, or you can have LTSP authenticate to active directory through other methods. Really, up to you and you renviroment
09:06
Well, you *can*. However, if your using say, local firefox apps, that can get difficult. Also, they'd all have the same home folder, which can lead to all kinds of shennaigans
09:07
<tech_dvo>
is there a good way of managing these many accounts?
09:07
<robehend1>
ldap
09:07
<tech_dvo>
i heard about that
09:08
does it have a GUI manager or something?
09:08
<robehend1>
many of them, actually.
09:08
google search of ldap gui gives tons of options

<moldy>
hi
11:12
some days ago, the guest login button on my clients disappeard (ubuntu 10.04). what could be the cause for this?
11:15
<Gadi>
moldy: did something change in your lts.conf?
11:15
<moldy>
Gadi: i set LDM_USERNAME and LDM_PASSWORD for some clients
11:16
<Gadi>
perhaps you introduced a syntax error?
11:16
<moldy>
i am not sure if this is related, though. the guest button disappeard on all clients
11:16
<Gadi>
I would log into a client, bring up a local xterm and try: getltscfg -a
11:16
<moldy>
that sounds like a good command to be aware of :) thx
11:17
getltscfg -a shows nothing
11:17
<Gadi>
in that case, you are not even getting an lts.conf
11:17
it is not being tftp'd
11:17
<moldy>
hm, ok
11:17Kicer86 has quit IRC
11:17

so i guess i was editing the wrong one the whole time? that is weird
11:18

any changes to tftp?

11:18

something is fishy

tftpd log shows this: Jan 20 18:16:48 whserver in.tftpd[24589]: RRQ from 192.168.0.173 filename /ltsp/i386/lts.conf
11:19
.173 is the client i am testing with right now
11:19
umm wait... could be permissions on the lts.conf
11:20
now i remember :) doh
11:20
i set it to 600 after putting passwords in there
11:21
does lts.conf need to be world-readable?
11:21Gremble has joined #ltsp
11:21
<Gadi>
it needs to be readable by the user that the tftpd runs as
11:21
I believe
11:21
<rpm_>
I am running an ubuntu 10.04.1 ltsp-cluster and I was wondering what packages need to be installed to the ltsp image in order to run firefox as a local app with support for wma and quicktime files?
11:22
<Gadi>
rpm_: the same things you had to install to get that support on the server
11:22
<moldy>
Gadi: thanks
11:23Gremble has quit IRC
11:24
<Ghidorah>
Does anyone know how one would go about disabling pulseaudio or audio altogether on LTSP?
11:25
<Gadi>
SOUND=False
11:25
<rpm_>
That's what I figured but I can't seem to get the right combination, does anyone have a list of packages or know of a site that lists the specific pacakges? I can't get it to play embedded in the browser, I have to download it first and open it outside of firefox.
11:26
<Gadi>
rpm_: try installing vlc or something in the chroot
11:26
<rpm_>
tried that
11:26
no joy
11:26
<moldy>
hm, giving user tftp read permission does not seem to work
11:28
<rpm_>
Gadi: What about downloading the fat client image and running that instead? Do you know if that has the support I am looking for?
11:28
<alkisg>
rpm_: try installing ubuntu-restricted-extras
11:29
<rpm_>
I have those installed as well
11:30
<alkisg>
rpm_: and what do you have currently? Firefox as a localapp but without wma etc support?
11:31
<rpm_>
Yes, it seems to load a player in the browser but does not play the video.
11:31
<alkisg>
moldy: ps -ef|grep tftp, as what user does it run? (I'm using dnsmasq so I can't see for myself...)
11:35
rpm_: do you have a URL handy for testing?
11:38
<rpm_>
I am having trouble with this site http://www.californiastreaming.org/new.asp?error=badAccess&redirectUrl=%2Fstreaming%2FdigitalHome.asp but I can't give out the login credentials on an open forum
11:38
I am also having trouble on the quicktime trailers site
11:38
anything that is flash works fine
11:41
alkisg: What do you think about using the fat client imaged refered to on this site http://www.stgraber.org/2010/01/ ? Do you know if it has the support for quicktime and wma files?
11:45
<alkisg>
rpm_: sure, I had no problem watching quicktime trailers from fat clients

I'll give that a try then
11:54
<robehend1>
rpm_: also, could go nuts and give it the whole ubuntu-restricted-extras package in the chroot

<yeedl>
any of yall got any experience with ltsp+rdesktop?
12:00
cant seem to get sound redirect workin
12:08
<rpm_>
robehend1: I actually tried that, I think something has gone wrong with my image so the fat client image is looking more atractive to me because it may require less setup time and better performance at the terminal. Thanks everyone!
12:10
<yeedl>
unsure if its an rdesktop issue or an ltsp issue. a)rdesktop on screen7. no sound. b) regular ldm to gnome session. yes sound. c) regular ldm to gnome session to rdesktop, no sound.
12:10
suppose all signs point to rdesktop? hmph
12:11
<Gadi>
yeedl: what params do you pass to rdesktop?
12:12
do you pass: -r sound:local
12:26
<robehend1>
rpm_: I'm using fat clients for that very reason, does a great job
12:28
<Ghidorah>
Are there multiple ways to load balance in LTSP? More specifically is DHCP round robin the only way?
12:29
<robehend1>
i thought cluster could go by load on the servers as well. no clue how though, if it can
12:30
<yeedl>
yea, only -r sound:local
12:30
rdesktop -f -r sound:local
12:33
seems like it is rdesktop, if i rdesktop from the ltsp machine (its a virtualbox machine) sound also doesnt work.
12:33
<robehend1>
yeedl: could be virtualbox, since you dont have the extensions installed
12:35
<yeedl>
but i do get sound just fine when i have a normal ldm+gnome ltsp session from a client computer
12:35
and i do get sound from the ltsp machine just fine.
12:35
dunna how virtualbox can effect rdp if sound already works on my ltspmachine
12:36
<robehend1>
cuz virtualbox has to pass the sound to your hardware as well, could be the bottleneck. Try the rdesktop thing on a client pc, make sure it doesnt work there?
12:36
<Gadi>
yeedl: have you enabled rdp sound in windows?
12:36
it is disabled by default
12:38
<mgariepy>
Ghidorah, ltsp-cluster can loadbalance users on different applications servers by looking at load, avalaible cpu, avalaible memory, munber of sessions etc.
12:39yeedl_ has joined #ltsp
12:39
<Ghidorah>
mgariepy: Do I have to use a linux DHCP server in order to use ltsp-cluster?
12:39
<yeedl_>
erm. accidently restarted this vbox.
12:40
i supose if i can get sound working on the ltsp, clients rdesktop sound would work too
12:40
<mgariepy>
Ghidorah, not really, depend on what you want to do.
12:40
<yeedl_>
alright, gunna head over to #rdesktop heh
12:40yeedl has quit IRC
12:40yeedl_ is now known as yeedl
12:41
<mgariepy>
you can have a simple setup like: on server to boot and get your configuration and 4 applications servers
12:41
<Ghidorah>
That is what I'm looking to do
12:41
<mgariepy>
everyone would boot from the same nbd image and they will uses different applications server to log in
12:42
<Ghidorah>
Right now I have 2 different LTSP servers
12:42
where I manually do a DHCP reservation to specifiy which one a client goes to
12:43
I'm looking to add an additional app server to provide better performance
12:48
mgariepy: Do you have any suggestions on how to set it up? I've looked at this documentation but it requires a linux DHCP server. https://help.ubuntu.com/community/UbuntuLTSP/LTSP-Cluster
12:52
<rpm_>
robehend1: Yes cluster does balance the load but when using multimedia like flash, quicktime videos, etc. with firefox it performs very poorly. I also get issues with sound when I have lots of students logged into the servers. I want to only run those apps as local apps but that seems to be too time consuming so running a fat client is the best way.
12:57
<alkisg>
rpm_: what are your client specs, ram/cpu?
13:00yeedl has quit IRC
13:06vagrantc has joined #ltsp
13:19
<rpm_>
alkisg: I have 90 intel atom clients with 1 gig of ram each, and then I have a mix match of about 40 older 1.5 to 2.0 GHZ intel celerons with 256 mb to 512 mb of ram
13:19
<alkisg>
I'd use a fat chroot for all those, with FAT_RAM_THRESHOLD=300 MB
13:20
<robehend1>
random question: If i was to copy a working /opt/ltsp/* folder, plus the associated /var/lib/tftpboot/ltsp/* folder, and configured inetd.conf to match on a new server, should it work
13:20
alkisg: you can set a max for fat_cam in the lts? wooo
13:20
er..fat ram..
13:20
<alkisg>
Yup. Either that, or hardcode mac addresses and specify LTSP_FATCLIENT=true/false...
13:21
<rpm_>
if I do this do I even need the app servers anymore? It looks like the system would run completely off of the image, is that right?
13:21
<robehend1>
yours is easier ;)
13:21
<alkisg>
robehend1: about the server, sure, and specifically you only need /opt/ltsp/i386, the others are generated with ltsp-update-image --force.
13:21
rpm_: right
13:21
<robehend1>
alkisg: nice. redoing a server, and wanting to throw it on a backup for the mean time
13:22
<rpm_>
Where would the user profiles be stored then?
13:22
<robehend1>
server
13:22
<alkisg>
sshfs or nfs home on some server
13:23
<rpm_>
Where do I specify that?
13:23
the server to use I mean
13:24
<alkisg>
By default the clients authenticate on the boot server, and use sshfs for /home on that server
13:24
You can change things there, e.g. set LDM_SERVER, or NFS_HOME or other stuff, depending on what you want
13:25
<rpm_>
I am authenticating to AD by way of likewiseOpen, would I just install that on the root server or is it not possible?
13:25
<robehend1>
yes, rpm
13:26
I've got it on my server, and it runs fantastically
13:28
haven't gotten around to trying it with cluster, though.
13:28robehend1 has left #ltsp
13:28
<rpm_>
With cluster, wouldn't the app servers be doing authentication?

robehend1: With cluster, wouldn't the app servers be doing authentication?
13:30
and nothing else, or did I missunderstand?
13:30
<robehend1>
im not sure on that, to be honest. I'm still trying to wrap my head around cluster. I'd think its whatever server you setup as the root though, isnt it? since thats what your authetnticating into?
13:30
<mgariepy>
Ghidorah, I don't have more documentation then this and i'm not quite familiar with using other dhcp server.
13:31
<alkisg>
mgariepy: is something special needed on the dhcp server for cluster?
13:31
<mgariepy>
no
13:31
<rpm_>
No, with cluster all you get from the root is the image and then you log into the app server that the load balancer sends you to.
13:31
<alkisg>
mgariepy, Ghidorah: Then the current documentation on the wiki about windows dhcp servers or proxy dhcp servers should apply...
13:31
<rpm_>
It makes central profile storage interesting to say the least.
13:32
<mgariepy>
the only thing different with ltsp-cluster is this file : /etc/ltsp/getltscfg-cluster.conf
13:32
<Ghidorah>
So basically I just have a root server that does load balancing
13:34
<rpm_>
Yup, and there is a web page that allows you to basically administer the settings you would normally put into lts.conf
13:34
<alkisg>
And how is /home and user accounts handled between app servers?
13:35
<robehend1>
thats what i'm wondering, myself
13:35
i thought the homes were on the root server, while the app servers just supplied, apps.
13:35
<rpm_>
each app server has it's own directory but you can link them all together with an nfs share
13:35
<alkisg>
And user accounts?
13:36
<robehend1>
just keeping the uid's the same..
13:36
<rpm_>
each app server needs an identical set
13:36
<alkisg>
Is that done automatically? Or the sysadmin needs to transfer the uids/gids?
13:36
passwords etc etc?
13:37
<mgariepy>
we usualy uses an ldap server for accounts and a nfs server for homes.
13:37
<rpm_>
you need to create a file for bulk user import and add them using the newusers command (I think, let me check on that)
13:38
I would us ldap but we already have AD so I have to use it for now and I just don't have time to learn ldap since I am still learning ltsp-cluster
13:38
<alkisg>
OK I do have a python app for user account backup/restore that I could use - I was just wondering if it was somehow done automatically
13:38
<rpm_>
no, not that I know of. If you find a way please let me know!

13:44
<alkisg>
Mass user creation, backup + restore
13:44
<robehend1>
i just make the teachers come to me. It scares me to give them access to the servers
13:44
<alkisg>
Nah here the computer teachers are also sysadmins, each one in his lab/school
13:44
<robehend1>
ah, that makes sense then
13:45
ours are still high school teachers..and ya, technical skills arent high
13:45
<rpm_>
We are not blessed with a highly technicall teaching staff either.
13:45

I am trying to install Edubuntu to be a small server in a school environment (ideally to also act as a LTSP server some of the time) I have 3x 500GB drives and was thinking of doing it as RAID5 but that does not seem to be an option during installation. Advice?
15:00
<robehend1>
does your motherboard support raid?
15:01
if not, you need to use the alternate disk, if i remember right.
15:02
<masai47>
is there an alternative disk for Edubuntu?
15:02
<robehend1>
lemme check
15:03
<masai47>
I had an alternative disk for Ubuntu and used that to set up partitions as RAID, but then Edubuntu would not recognize it when I tried to install
15:03
thanks
15:03
<robehend1>
hmm, i dont see an alternate install, guessing since they rolled it onto a dvd, they included it..
15:03
you tried doing the standard manual partitioning setup for ubuntu software raid?

I was working with someone who had an Ubuntu variant for small business servers and we were able to create the partitions (or thought we had) using that as a live CD
15:06
<robehend1>
https://help.ubuntu.com/community/Installation/SoftwareRAID
15:06
try giving that a shot? its 9.10, but should still be relevant. Sadly, I haven't tried the software raid in 10.04
15:07
<masai47>
but when I tried with my Edubuntu live USB it would not recognize the RAID partion (gparted would crash on start up) and disk utility saw the RAID partion but could not mount it
15:07
ok
15:07
thanks
15:07
<robehend1>
no prob, wish you luck
15:18
i should give Edubuntu a shot again, one of these days. havent touched it since 8.10

markit: Why do you want a "." in the username?
17:44
<masai47>
I am trying to install Edubuntu on RAID and it does not seem to be working
17:45
<markit>
rpm_: is mole "email - like", seems more easy to use than no separator, or a "-"
17:45
(a-brown)
17:45
masai47: raid with a real raid hardware, bbu and write back? if you are using "on board raid" you'd better give it up, does not make sense
17:46
(is "fake raid", better use softraid from GNU/Linux but better have raid10 and true raid controller with cache)
17:46
<masai47>
this would be software raid
17:47
<rpm_>
Oh, we just use the first inital and last name without a separator, guess it's personal preference.
17:47
<markit>
rpm_: how do you manage duplications ("collisions")?
17:47
like antony brown and andrew brown?
17:48
I'm planning to use last year's birth date (I'm setting up a school ltsp)
17:49
<rpm_>
with student names we either use their student id or there full name with middle initial. Not the most creative but it works for us.
17:50
<masai47>
markit: I have 3x 500GB hard drives and was thinking of doing raid5 (I have no experience with raid) The Edubuntu live USB I used does not give any options for setting up the partitions as raid, so I used a zentel? alternative install CD which worked fine for setting up the partitions (I think) but would not boot into it
17:50
<markit>
rpm_: what are "middle initials"?
17:51
<rpm_>
the first letter of their middle name.
17:51
<markit>
masai47: sorry, I use proxmox (bare metal virtualization), so I only have experience with "hardware raid", a virtualization server needs very high performances and realibility
17:51
rpm_: mmmm like Richard Mattheu Stallman, being Mattheu the "middle name"? In Italy we don't have
17:52
<rpm_>
yes, sorry didn't realize where you were I'm in California
17:54
<markit>
rpm_: so every one in the US has a middle name? really?
17:54
<rpm_>
generally speaking yes
17:55
<markit>
I see
17:55
<masai47>
yeah, this is much lower level. I just thought it would make sense to take advantage of the extra hardrives in this way. on more of an LTSP question, I have a computer with a intel core 2 duo processor, 4GB of ram, do you think this is good enough to run edubuntu on a few thin clients?
17:55
<rpm_>
how many?
17:55
Sup3r5640
17:55
oops i did it again
17:56
<markit>
masai47: sure, with Gbit lan and not too heavy tasks (no blender or video rendering...)
17:57
<masai47>
how slow would it be without Gbit Lan (the second Gbit network card was not in stock and will be installed at a later date)
17:57* markit has to change all his user creation script and documentation, sigh... better avoid dot even if should be ok
17:58
<markit>
masai47: you need to try yourself, I have no "numbers", I wanted to point you to the most probable bottleneck (you need a Gbit switch too, or at least a 100/mbs with a gbit port to connect the server)
17:59
<masai47>
that is the plan
17:59
<markit>
so start with what you have, you can only improve :)
18:00
but I would try to have a 4 core, if possible
18:00
<masai47>
Right now I am still stuck on the installation stage with edubuntu and this is the only channel where I have gotten a response to my questions
18:00
<markit>
just a feeling that works better in multiuser
18:00
<masai47>
really small school in Africa
18:00
<markit>
are you in africa? from africa?
18:02
<masai47>
I dont know much about LTSP, but I was reading about DRBL and wondering if I can take advantage of the fact that the clients all have brand new celeron processors with 2GB ram
18:02
in Botswana as a Peace Corps Volunteer
18:03
<markit>
masai47: ltsp has also a "fat client" config possibility, so programs are run locally
18:03
with celeron and 2gb ram could be viable and better scalable solution
18:03
<masai47>
yeah
18:04
<markit>
so if you are just testing, give up raid and start becoming familiar with ltsp
18:04
once you have a clear picture, and done some test, is also easier tailor hw needs
18:04
<masai47>
right now the clients only have 8GB flash drives for memory and they want to install Windows on them
18:04
ok
18:04
<markit>
why on earth Windows?
18:05
is a suicide for every Free people, and even more for "poor" countries that need independence and knowledge
18:05
<masai47>
you are preaching to the choir
18:06
and I have given up installing windows on the clients
18:07
but I tried installing Edubuntu as well and it wont boot so I am wondering if the school was given a bunch of crap USB drives
18:07
<markit>
btw, where are you from?
18:08
<masai47>
originally California but Africa has been my home for most of my life
18:08
you?
18:08
<markit>
mm so no windows pre-installed, and they have 100$ for license cost + all the related sofware (like antivirus) etc?
18:08
me Italy
18:09
<masai47>
no, they were going to go the illegal license route for now
18:09
<markit>
well, does Kubuntu/ubuntu 10.10 boot or not in those pc?
18:10
<masai47>
but, I cant complain, because the only reason they came to me was that they were open to Linux
18:10
my edubuntu live USB booted fine
18:10
and it seemed like I just installed fine
18:10
but once I removed my USB I now only get a read error
18:11
not sure if I should work on getting a client running as a test or work on the server (and give up on RAID
18:11
<markit>
error at boot time you mean?
18:12
are you new only of ltsp or not very found in GNU/Linux in general?
18:13
<masai47>
I have been using ubuntu as my personal desktop for a few years, but just as a basic user (and this makes me an IT expert here)
18:14
<markit>
GNU/Linux world is fantastic but is not "point and click", you have to get a "low level" knwoledge to troubleshoot fine
18:15
sometime it seems non-sense, a lot to learn just to do little, but in the long term is the right way
18:15
<masai47>
Working on the core2duo with the 3x 500GB any advice on partitioning (hoping this computer can act as a LTSP server, and a general file server and proxy server
18:15
I completely agree, and I find that I have always figured stuff out for myself on IRC or forums
18:16
<markit>
I would install in the first hd, and leave the second for additional storage, and the 3° as "local backup". About partitioning, I can't sugges, I'm confused myself
18:16
I mean, I've tried many solutions but not being able to dinamically resize and reallocate space is a risk
18:16
usually I would create a separate boot one
18:16
<masai47>
but I got asked yesterday to get involved in setting up this computer lab, we bought 9 machines today, and they want them at least partially up and running by tomorrow
18:17
<markit>
ok, if you have to do something for tomorrow, install in the server first... at least you can show a shinning desktop full of fabolous Free (as in Freedom) applications
18:18
then you have some more time to make ltsp work
18:18
you can try ltsp, and if you want to restart, is just a matter of removing ltsp directories and restart from scratch
18:18
without having to reinstall the whole server
18:19
<masai47>
what I wanted to do was have a 300mb /boot partion on each that would be linked as RAID1, 2GB of swap on each, and then the rest linked as RAID5 as an EXT4 flilesystem
18:19
<markit>
(hope you have a good internet connection though... or squid as proxy server with big cache)
18:19
<masai47>
iss Master Boot Record or GUID better
18:19
<markit>
you are going to hurt yourself...
18:19
<masai47>
someone advised squid
18:20
<markit>
with 3 HD, you can't have raid1 + raid5
18:20
<masai47>
ok
18:20
is that my problem
18:21
just do raid5?
18:21
<markit>
what is your goal? redundancy or space?
18:21
<masai47>
redundancy
18:21
<markit>
ok, raid5, but raid is a bad idea OMHO
18:22
it becomes overcomplicated in case of failure
18:22
without dedicted hw has bad performances
18:22
and nothing saves your soul better than a backup
18:22
<masai47>
either way I am not going to be there to help
18:22
<markit>
with raid5 cpu will work for parity computation
18:23
<masai47>
so, there might not be someone making backups
18:23
<markit>
belive me, you can setup a rsync-backup crontab script to the 3° hd
18:23
<masai47>
but if it is RAID and there was a true crash they could probably get someone out who could regrow the array
18:23
<markit>
with the content of the children's homes
18:24
how can they tell if a hd is faulty?
18:24
they will noticed only when the second breaks
18:24
but then nothing will be recoverable
18:25
<masai47>
no, I was going to have it so it would not boot up if all 3 were not working
18:25
<markit>
well, I will not insist :)
18:25
<masai47>
no, I am open to any advice
18:26
you think just install on the first?
18:26
<markit>
that's my opinion
18:26
<masai47>
I am just not sure whats the best way to set it up so someone else can fix it
18:26
<markit>
I've no idea of the skills available there
18:27
<masai47>
and is simple for people who have no experience
18:27
<markit>
maybe they are more found in "format c:" command
18:27
<masai47>
not much
18:27
<markit>
mmmm you can install everything on the first drive
18:27
the CLONE on the second when you are happy
18:27
and leave inside unconnected
18:27
<masai47>
so just install to the 1st Hard drive and figure out what to do with the other 2 later
18:28
<markit>
if something breaks, they can remove sda connection cable and plug in second hd
18:28
3° being the data backup :)
18:29
I go back to my troubles with a user creation script, I will look at this windows time to time, see you later
18:29
(1.30am here, and I have to finish tomorrow morning)
18:30

do i have to install a dhcp server to get ltsp working?
19:07
shouldn't it get the ip from dhcp?
19:07
please help me out i am a newbie
19:19
<cliebow>
you will need some dhcp server
19:19
can your dhcp provide vital info like bootserver and such
19:20
a lnksys router wont necessarily do the trick
19:22
whata linuxdo you want to use?
19:22
as a server
19:27
<kannan1222>
i have debian
19:31
what are the vital information does it need to pass
19:31
i have dd-wrt installed
19:32
<cliebow>
are you pxe booting? need to pass a boot image name to you r pxe client..
19:32
<kannan1222>
yes
19:33
<cliebow>
i must stop as i am so rusty at this..you need someone else to help you
19:33
<kannan1222>
oh okey
19:33
i thought that was the job of the tftp servef
19:34
<cliebow>
do some studying .tftp will do the file transfer after the pxe repsonse passes the filename to request..but
19:34

<kannan1222>
i cant install ltsp-server-standalone
19:42
someone pls help me
19:45
can anyone see this
19:45
<markit>
ltsp-server-standalone is in regular debian repo
19:45
<kannan1222>
it wont install for some reason
19:46
<markit>
btw, is 2.45 am here, and I've no much time/resources to help, sorry
19:46
troubleshooting "some reasons" is beyond my forces now
19:46
<kannan1222>
it says cant find package ltsp-server-standalone
19:46
<markit>
kannan1222: distro?
19:46
<kannan1222>
i don't know if i need to add some sources
19:46
<cliebow>
debian he saya
19:47
<markit>
ok, aptitude update then aptitude install ltsp-server-standalone
19:47
<kannan1222>
debian
19:47
<markit>
the package is in "main" as far as I know
19:48
kannan1222: debian sid? testing? lenny?
19:48
<kannan1222>
lenny
19:48
<markit>
ok, should be there
19:48
but I'm not sure
19:48
<kannan1222>
i am using a live cd though
19:49
<markit>
so what do you want to do with a live cd? you will never be able to make ltsp work, I guess
19:49
<cliebow>
you should install
19:50
<kannan1222>
works after aptitude update
19:50
i have a question
19:50
<markit>
kannan1222: yes, but you will discover that has to build the chroot environment for clients, something you can't do in a live
19:50
<cliebow>
find some pos box and install debian or ubuntu..whatever..wont take much of a box to demonstraat the awesome power
19:50
<kannan1222>
oh oh
19:51
thanks for that info
19:51
you saved me from wasting a lot of time
19:51
<cliebow>
you hav the resources here to alk o the guys that wrote all this
19:51
<kannan1222>
okey now i need to download debian again \
19:51
you can't install debian froma live cd?\
19:51
<markit>
kannan1222: you'd better read some tutorial first or generic info, you seem at too low knowledge of ltsp to make sane decisions :)
19:52
kannan1222: I've no idea, in any case install testing, is almost the new stable
19:52
('squeeze')
19:52
<kannan1222>
whats testing
19:52
<markit>
is the release is going to become "stable"
19:52
in debian you have stable, testing, instable and experimental
19:52
<cliebow>
testing is one iota short of stable
19:53
<kannan1222>
oh okey okey
19:53
oh okey okey?
19:53
<markit>
try http://cdimage.debian.org/cdimage/weekly-builds/
19:53
just download cd1 and start from there
19:54
or try an edubuntu dvd
19:54
<kannan1222>
wow
19:54
theres 53 cd?
19:54
<markit>
(btw, I use kde, not gnome)
19:55
kannan1222: you just need the FIRST one, then will download the necessary packages from internet
19:55
<kannan1222>
that will kill my bandwidth
19:55
<markit>
Free (as in Freedom) software is an ocean of programs you can swim at will :)
19:55
<kannan1222>
i am limited to how muchi can download
19:55
i wouldnt mind if it is like 5r gig\
19:56
it seems like its going to be much more then that
19:56
<markit>
it's much smaller
19:56
<kannan1222>
hm
19:56
ok
19:56
<markit>
but ltsp will download a "mini installation" again in it's subdir
19:56
<kannan1222>
maybe i am looking at the wrong iso
19:56
<markit>
32 or 64 bit?
19:56
if is a test machine, use 32
19:57
http://cdimage.debian.org/cdimage/weekly-builds/i386/iso-cd/debian-testing-i386-CD-1.iso
19:57
or you could go for the net install
19:57
well, sorry, 3am here, I can't even type anymore
19:58
hope someone else will help, or better read documentation first
19:58
and/or watch some video on youtube about ltsp
19:58
or whatever
