Hello. On some clients I need /var/spool to be mounted with much larger size than the default value of half the RAM (yes, I got swap over NBD). Any idea what to edit here?
03:15
<vagrantc>
vlt: ubuntu, debian, or ?
03:16
<vlt>
vagrantc: Ubuntu (Dapper 6.06)
03:17
<vagrantc>
vlt: using ltsp5 and such ?
03:18
<vlt>
vagrantc: according ogr_a it should be v5
03:18
<vagrantc>
just want to make sure you're not using ltsp-utils and ltspadmin and stuff

vlt: look for a line in /opt/ltsp/i386/etc/init.d/ltsp-client-setup like this: mount -t tmpfs -o mode=0755 tmpfs $tmpfs_dir
03:20
<vlt>
vagrantc: I already unzipped /opt/ltsp/i386/initrd... but can't find exactly where to place the size paramater for the ...
03:20
vagrantc: Yes, found the line
03:20
<vagrantc>
vlt: change it to: mount -t tmpfs -o mode=0755,size=XXXXm tmpfs $tmpfs_dir
03:21
<vlt>
vagrantc: I'll try, thank you.
03:21
<vagrantc>
where XXX is the number of megabytes of ram
03:21
<vlt>
vagrantc: Any quick idea how to apply this to certain clients only?
03:21
<vagrantc>
vlt: nope
03:22
<vlt>
ok
03:22
<vagrantc>
well, actually ...
03:22
you could set some sort of variable in lts.conf
03:23
and then put the size stuff in an if statement
03:23
<vlt>
vagrantc: Aah, yes, sounds good.
03:24
<vagrantc>
if [ "$SOME_VARIABLE" = "true" ]; then mount -o remount,size=XXXXm $tmpfs_dir ; fi
03:24
something like that
03:25
dapper is kind of antique for LTSP
03:26
i'd best get some sleep

Hello (ogra), now that Ubuntu 7.10 is out would you reccommend "upgrading" from 6.06 LTS in a production LTSP environment?

doing great

how's things there?

I'm doing well, Jen and Morgan are sick.
08:44
<jammcq>
bummer
08:44

which means Jen's remembering why it is she married me right now. :-)

08:59* sbalneav taps microphone
08:59
<sbalneav>
Is this thing on... Is this thing on...
08:59
<jammcq>
nope, can't hear you
08:59
<sbalneav>
Who is it who does that in their comedy routine?
08:59
<jammcq>
umm
08:59
every comedian on a bad night
08:59
<sbalneav>
heh
09:00
well, yeah.
09:00
But there's one who does it all the time in his act. It'll come to me eventually.
09:03
exodos: Pinging again...
09:08pwest has joined #ltsp
09:08
<sgonzalez>
sbalneav: I'm not exodus, but I'll answer ;) Good morning. Last week we chatted a bit about the server freezing on me and you suggested a memtest86. In 48 hours it finished 39% of the test with no errors. I don't have 4 days to let it run until we get to Thanksgiving. However, I'm skeptical about memory being the issue. I talked to David Trask (tech person at school in Maine running edubuntu). He doesn't run kernel because it doesn't work for him either
09:08
. I would really like my 6gb... any other thoughts? (sorry for the really long post!)
09:09
<pwest>
Is it possible to change the interface language of the LDM to, in this case, German?
09:10
<sbalneav>
pwest: I don't think there were any translations done for de yet.
09:11
<pwest>
okay, so it can't yet be changed
09:11
<sbalneav>
sgonzalez: None. This is a server kernel issue, so I'd simply file a bug.
09:11
pwest: Yeah, by next time, I'd expect we'll have a fuller set of translations.
09:11
<pwest>
I thought it would be a matter of installing a language-pack and setting some locale variable
09:11
great thanks for the info
09:12
<sbalneav>
Well, it would be.
09:12
<pwest>
but
09:12
<sbalneav>
but if the strings aren't translated, then there's nothing to sub in :)
09:12
<rjune_>
pwest: sounds like a translator is needed.
09:12
<sbalneav>
Plus, it's entirely possible that my i18n work I did on LDM is completely and utterly wrong :)
09:13
<pwest>
okay, I assumed it would grab strings from the GDM trl's
09:13
<sbalneav>
seeing as how I have no clue as to how to do i18n in C :)
09:13
<pwest>
let's hope not
09:13
<sbalneav>
I followed some examples, and crossed my fingers.
09:14
<sgonzalez>
sbalneav: I meant to ask you this at the beginning: Are you the right person to ask these types of questions? You tend to have answers so I keep asking you, but let me know if I should bug someone else! And where do I file a bug (another question... sorry!)
09:14
<sbalneav>
I'll leave it up to people who need other languages to check my work and send me patches :)
09:15
sgonzalez: Well, launchpad's the place to file bugs for ubuntu/edubuntu, and I try to help as much as I can, but this isn't anything I know about in detail. I have IBM X series servers, and the -server kernels work fine for me, so there's not much I can offer.
09:15
<pwest>
I'm just a foriegner here in Germany myself, so I can't really do great trl'ing
09:15Clown-MG has joined #ltsp
09:16
<sgonzalez>
Thanks :) I'll go look on launchpad and see what I can find there.
09:16
<sbalneav>
I'm pretty much at the point where we should all just learn to speak and read/write esperanto. Think of the amount of coding it would save! :)
09:17
Plus, I found a poster on the weekend telling me how to order a beer in Esperanto, so I'm pretty much set now :)
09:17
<pwest>
thanks for your work

<sunru>
hi
10:29
<sbalneav>
Hello sunru
10:30
<sunru>
ok i've just realized i've been reading the 4.0 docs
10:31
sbalneav: hi just a bit stuck on the whole root mounting part.
10:33
<sbalneav>
Well, first off, how about telling us what version of ltsp you're running on what server?
10:34
<sunru>
server running gentoo
10:34
LTSP-5?
10:34
<jammcq>
you wish
10:34
ltsp-5 doesn't exist on gentoo yet
10:34
it's prolly ltsp-4.2 you have
10:37
<sunru>
how does the client have access to the server applications? is the root in /opt/ltsp/ temporary?
10:37
<jammcq>
the client doesn't have access to those apps
10:37
<sunru>
i'm just stuck on that bit.
10:37
<jammcq>
you use the thin client to log into the server
10:37
you run all apps ON the server
10:37
but they are displayed on the client. the miracle of the X Window System
10:37
<sunru>
yes i know that.
10:38
<jammcq>
if you know that, then why are you asking how the client has access to the apps?
10:38
<sunru>
what are the client roots in /opt/ltsp/
10:38
<jammcq>
thats the root filesystem for the client
10:38
/opt/ltsp/i386 is mounted via NFS on the client
10:39elisboa has quit IRC
10:39
<sunru>
ok
10:39
<jammcq>
but there's no applications there
10:39
only operating system things
10:39
<sunru>
so for the client to "execute" /usr/bin/oowriter on the client requires /usr to be mounted via NFS?
10:40
<jammcq>
no
10:40
<sunru>
on the server rather.
10:40
<jammcq>
you don't get it. the client doesn't "execute" oowriter
10:40
the user actually has a session on the server
10:40
the SERVER "executes" oowriter
10:41
<rjune_>
I executed oowriter.
10:41
<sunru>
are you done making corrections on symantecs?
10:41
<rjune_>
the sumbitch was using too much RAM
10:41
<jammcq>
sunru: you are asking how things work. I'm telling you
10:41
but it seems you don't understand
10:41
<sunru>
jammcq: no your being a smartass
10:42
<rjune_>
uh oh
10:42
<jammcq>
i'm trying to help you here
10:42
I'm telling you the apps don't run on the client
10:42elisboa has joined #ltsp
10:43
<sunru>
so is /usr mounted via NFS ?
10:43
<jammcq>
when you log in via a thin client, your entire session is running on the server
10:43
Gnome, KDE, whatever, it's all running on the server, displaying it's output on the client
10:43
<sunru>
jammcq: NO SHIT!
10:43
<jammcq>
NO, /usr is not mounted via NFS
10:43
<sunru>
typical IRC wanker
10:43
<jammcq>
only /opt/ltsp/i386 is mounted
10:44
ok, someone else wanna explain to this guy how it works. apparently i'm not able to
10:44
<Blinny>
Wow.
10:44
<cyberorg>
sunru, btw jammcq is the smartass who started whole of ltsp project that we all love
10:44
<rjune_>
magic.
10:44
<Blinny>
sunru: Checkit. The client boots and yes, there is a minimal system mounted via NFS or NBD
10:44
<rjune_>
it works on magic
10:45
<sunru>
so server /usr is a symlink -> /opt/ltsp/i386?
10:45
so server /usr is a symlink -> /opt/ltsp/i386/usr
10:45
<jammcq>
no
10:45
<Blinny>
sunru: However, that system is only there to open a connection to the server. When you run something (OpenOffice, FireFox, etc) you're running applications directly on the server. There is no symlink, there is no mounting.
10:45
<jammcq>
why does the thin client need /usr ?
10:45
answer.... it doesn't
10:45
<Blinny>
You_work_on_the_server.
10:45
sunru: Think of it as a very long cable for your mouse, keyboard and monitor, connected directly to the server.
10:45
<sunru>
gawd
10:45
<Blinny>
That's what the software does. Just makes a very long software cable.
10:46
So, if you have GIMP installed on the server, you can run it from the client.
10:46
<sunru>
yes i know.
10:46
<Blinny>
If you have ____ installed on the server, you can run it from the client.
10:46
<jammcq>
"From" the client, but not ON the client
10:46
<sunru>
yes i know.
10:46
<jammcq>
ok, then what's the problem?
10:47
<Blinny>
The questions you're asking don't jive with you knowing that point.
10:47
<sunru>
/opt/ltsp/i386/usr is mounted via NFS as / on the client correct?
10:47
<jammcq>
no
10:47
but you are close
10:47
/opt/ltsp/i386 is mounted as /
10:47
<sunru>
ugh sorry i meant that.
10:48
sigh
10:48* rjune_ bows to jammcq. You're *VERY* patient
10:48
<sunru>
the problem is i know you know what im trying to get at.
10:49
<jammcq>
umm, apparently I don't, cuz we have this "mismatch of ideas" here
10:49
have you tried it yet?
10:49
<sunru>
on the server oowriter is in /usr/bin/
10:49
<jammcq>
yes
10:49
probably there
10:50
<sunru>
right so where is it in /opt/ltsp/i386?
10:50
<jammcq>
it's not
10:50
doesn't need to be
10:50
only thing the thin client needs is a kernel, some libraries, a shell, and the X stuff
10:50
with that, you can connect to the server and get a session running on the server
10:51
so now, your session is executing on the server's CPU.
10:51
all apps you run are running on the server, not the client
10:51
the client just gets you there
10:51
<nonsparker>
jammcq: does it work the same way with kiosk?
10:51
<sunru>
oh ic
10:51
jammcq: im sorry for the misunderstanding.
10:51
<jammcq>
nonsparker: kiosk means alot of things to alot of people
10:51
sunru: ok then, you starting to understand it?
10:52
<sunru>
yes
10:52
<jammcq>
cool
10:52
<nonsparker>
the build-kiosk
10:52
<jammcq>
nonsparker: sorry, dunno about that
10:52
<sunru>
i removed X from the equation
10:52
nonsparker: i cant see why not?
10:52
<Blinny>
sunru: In the future, you may wish to keep 'wanker' from your vocabulary when you're asking for help.
10:52
<nonsparker>
ltsp-build --kiosk
10:53
<sunru>
Blinny: sorry me and IRC don't mesh to well.
10:53
so whats the problem with LTSP-5 and gentoo?
10:53
<jammcq>
it's just not been integrated yet
10:54
it's quite a bit of work. ltsp-5 builds upon the distro packages, and needs to be carefully integrated into each distro
10:54
<sunru>
ok
10:56
<nonsparker>
so no one knows about the ltsp-build --kiosk?
10:57
ltsp-build-client --kiosk
11:00
no one?

[ogra]:: password expiration is not working in gutsy ?
11:14

sure it is
11:14

11:15
<cdealer>
ok, will ask to him
11:17
<sbalneav>
Should work.
11:17
<cdealer>
[sbalneav]:: hey... password expiration isnt working on gutsy ? Here after doing a usermod -e EXP_DATE user when trying to login it stays in the Verifying password... plase wait
11:18
<sbalneav>
Well, was working for me.
11:18
<cdealer>
[sbalneav]:: you do like I did ?
11:19
<sbalneav>
No, I use ldap, so usermod doesn't work well, so I have to edit the ldap entry manually.
11:19
I'll check right now.
11:19Guaraldo has joined #ltsp
11:19
<cdealer>
ok
11:19
<ogra_cmp1>
i think plain usermod -e worked here
11:19
when i tried
11:19
<Guaraldo>
sbalneav: Can you help me with an inssue?
11:19
<cdealer>
[sbalneav]:: are you using othe box with ldap for authentication? Im thinking about doing something like this here too
11:20
Im thinking about making webmail, logins and other stuffs to authenticate directly from a ldap box ...
11:20
<sbalneav>
I have a separate ldap auth server, yes.
11:20
<Guaraldo>
sbalneav: If I have the LTSP5 chroot on a server, but connecting on another server, how can I sync the ssh-keys?
11:21
<sbalneav>
Have a look at the edubuntu handbook. We've got a section in there on that.
11:21
ltsp-update-sshkeys --export

<stefan__>
hello, i have a question about serverSizing. I know there is a lot in the wiki, and on the mailinglists, but could not find an answer. What king of CPU do i need for 6 Clients working with OpenOffice and two are yousing videoplayer or Youtube? My old Server (P4 2Ghz, 1GB RAM,100 Mb Nics) cant handle youtube videos. Its very choppi even with one Client (533 Mhz, 128 MB Ram).
11:23
<rjune_>
Youtube is likely network bandwidth not CPU
11:23cyberorg has quit IRC
11:24
<rjune_>
upgrade the NIC to 1Gb and that should help
11:24
<ogra_cmp1>
in ltsp5 use LDM_DIRECTX
11:24
that will disable encryption of teh X traffic
11:24
<stefan__>
i tried both, ltsp42 and 5, and 4.2 is a lot faster.
11:24
<rjune_>
even still, video uses lots of lan
11:25
and he just told you why
11:25
<stefan__>
DO Ireally need 1GB Nic for simpoe youtube viedeos?
11:25
yep
11:25
<rjune_>
well, lets do the math
11:25
320 x 240 x 16 x 30
11:26
== 36.8 Mb/s for a 320 x 240 video at 16bit color and 30fps
11:26
there was work on XDamage so that only stuff that changed got updated, but I don't know where it's at
11:27
<joebaker>
Hmm... it would make sense to distribute the codec uncompressor to the thin client, wouldn't it?
11:27
<ogra_cmp1>
joebaker: half breeded :P
11:27cyberorg has joined #ltsp
11:27
<rjune_>
you would have to compress the entire X streem then
11:27
<ogra_cmp1>
run FF on the client
11:27
<rjune_>
stream
11:27
<stefan__>
whats FF?
11:27
<rjune_>
local apps are the historic way around it
11:27
FireFox
11:28
<joebaker>
No... FFMpeg
11:28
<ogra_cmp1>
no, firefox :)
11:28
<joebaker>
oh.
11:29
<ogra_cmp1>
ideally we'd have the XDamage fix rjune_ mentioned ...
11:29
<sbalneav>
cdealer: You might want to check on the thin client, with SCREEN_02=shell, and look at /var/log/ldm.log
11:29
<joebaker>
There are problems with running FF locally on the tc. I hope we can figure out how to integrate it with gnome to do this right.
11:29
<stefan__>
well.... should be a 1 Gb Nic on Serverside and 100 Mbit Nic for the thinclients enough?
11:30
<cdealer>
[sbalneav]:: I will first reinstall, im not sure if my backuped 7.04 files made some messy in the new instalation ... them I will try expire the logins again to see if the problem persists
11:30
<sbalneav>
cdealer: Did you rebuild the chroot?
11:30
<joebaker>
We need some sort of proxy between gnome apps and gconfd so applications on the local thin client and apps on the Terminal server all talk to the same gconfd daemon.
11:31
<sbalneav>
joebaker: That's a big job. Someone from Gnome will have to step up to the plate and offer assistance on that.
11:32
Since gconfd isn't network aware, it's not likely to happen soon, since gconfd's going to need some major work.
11:32
<ogra_cmp1>
thats why consolekit exists
11:32
<cdealer>
[sbalneav]:: I just backuped the some /;etc files, like password and shadow, I think the proble may be in here... all the ltsp instalation was made all again....
11:32
<rjune_>
ogra_cmp1: so xdamage isn't an option yet?
11:32
<ogra_cmp1>
rjune_: no idea :)
11:33
seems you followed close than i did :)
11:33
*closer
11:33
<rjune_>
stefan__: you should get much better performance from it, have you used anything to track network usage on the server?
11:33
ogra_cmp1: my info is a year old at best, so that's scary
11:33
<stefan__>
not yet.... what is the best tool for it?
11:33
<ogra_cmp1>
stefan__: also note there is more that makes a network ... its not only NICs
11:33
<rjune_>
MRTG + SNMP is easy
11:34
<joebaker>
Gconfd uses Orbit (iirc) which is network aware but there doesn't seem to be much documentation on it.
11:34
<rjune_>
heh, I did assume your switch supported at least one gigabit port
11:34
<ogra_cmp1>
well, just dont use HUB :)
11:34
<rjune_>
oh god.
11:34
that's wrong
11:34
a Gb hub?
11:34* rjune_ shudders
11:34
<ogra_cmp1>
people do it
11:35
nah, not GB
11:35
<stefan__>
i have only a 100 Mbit Switch at the moment
11:35Guarald1 has joined #ltsp
11:35
<rjune_>
stefan__: then a gigabit nic won't help
11:35
<stefan__>
so will to get one with 1 GB itlink
11:35Guaraldo has quit IRC
11:35
<stefan__>
o know ;)
11:35
<ogra_cmp1>
but having one HUB in your network can even make the network die if your server is connected via a gigE switch
11:35
<stefan__>

ogra_cmp1: I had a support call over the weekend with a customer that paid somebody twice what I make. It was so depressing
11:36
<joebaker>
I bet I could hack together some sort of gconfd proxy to make it network transparent.
11:36
<ogra_cmp1>
rjune_: time to raise the prices eh ? :)
11:36
<sbalneav>
By all means, start hackin :)
11:36

I was pretty close to offering him my services.

Hi! I have problems figuring out the dhcp settings for ltsp. Do /etc/dhcp.conf and /etc/tlsp/dhcp.conf have to be identical, or what's the difference between them?
12:05

/etc/ltsp/dhcpd.conf overrides all others
12:06

13:20
wifi connects me to dsl
13:21
<sbalneav>
ok, so you haven't set an ip address for he wired interface then, right?
13:21
You'll have to set a static IP address.
13:21
<upro>
sbalneav: no, it's all dhcp (from the dsl modem)
13:21
<sbalneav>
Something like 192.168.0.254
13:21cyberorg_ is now known as cyberorg
13:23
<upro>
sbalneav: a static adress for the server nic?
13:23

Yes.

If it's serving terminals, it should have a static address.

13:24
You're a champ!
13:25
sbalneav: if I use 192.168.0.254 as adress, 255.255.255.0 is the subnet, but what will be the gateway?
13:26
<sbalneav>
You don't need a gateway. The terminals themselves don't need to talk to anything but the server. Your applications run on the server, and there, you're using the wifi and it's gateway for internet access.
13:27
<upro>
sbalneav: ok. Then now I'll try to start my thin client...

sbalneav, i had it at 80 initially, and after this, I tried upping it to 95 - same deal.

15:46
the idea is using a softphone in the clients
15:47
<sbalneav>
You should be able to.
15:47
<sgtpepper>
is there any packages already for pulseaudio in ltsp
15:47K_O-Gnom has quit IRC
15:48
<sbalneav>
Yup. Ubuntu and debian use pulseaudio in LTSP5
15:49
<sgtpepper>
I'll try to do it with Fedora 8, or better yet with centos 5
15:53
well I can use the same tarball
15:54
<sbalneav>
Well, probably not, there's only source available for ltsp5
15:54
ltsp5 relies on tight integration with the distro
15:55
I beleive Fedora's currently being worked on now, but it's not available yet.

Is this a good place to ask about serving a floppy disk image using memdisk?
21:35
<sbalneav>
Memdisk?
21:36
<Databastard>
part of syslinux
21:37
<sbalneav>
Doubt many people would know about that here, but ask your question anyway.
21:37
Someone may know.
21:38
<Databastard>
I've also tried booting from a floppy image with "kernel floppy.img" but the PXE client does to multicolored ASCII garbage
21:40
<sbalneav>
Well, you'll need the pxe stuff from syslinux to boot from a pxe network card.
21:41
pxe wants a small boot loader to begin with, and the boot loader will load your floppy image from there.
21:41
Maybe if you tell us exactly what it is you're trying to accomplish, we might be able to help you better.
21:41
<Databastard>
So, if I'm using Edubuntu, I need to scrap all that and run syslinux?
21:41
Okay
21:43
At work, we currently use about 200 USB floppy drives to run a bootable dos disk to a bunch of terminals. The idea is to serve the floppy image from a server with PXE, tftp, dhcp.
21:44
I used Edubuntu which loads a linux kernal right out of the box
21:44
<sbalneav>
right.
21:44
So, what's on this dos disk?
21:45
Etherboot?
21:45Al-Khouli has joined #ltsp
21:45
<Databastard>
So I don't want that, I want to automatically load the dos image with diagnostics
21:45
no
21:45
Does that need to be in the floppy image?
21:45Al-Khouli has quit IRC
21:47
<sbalneav>
I'm sorry, I'm not understanding. What's on this dos image? Are these thin clients you're booting?
21:47BGomes has joined #ltsp
21:50
<Databastard>
It's an image of a floppy disk. The disk is bootable and runs a diagnostic program without user input. The clients have hard drives, but no external drives.

<sbalneav>
Ah, so this has nothing to do with ltsp per se.
21:55
ok
21:55
<Databastard>
all right
21:55
<sbalneav>
Sorry, couldn't understand what you were trying to do
21:55
<Databastard>
No problem
21:56
<sbalneav>
ok, well, you'll definitely need to use the syslinux pxe stuff
21:56
<Databastard>
That's what I was afraid of
21:56
Good night
21:56
<sbalneav>
Well, hold on.
21:56
you want help or not?
21:56
<Databastard>
Sure
21:57
I didn't want to be obtrusive or anything
21:57
<sbalneav>
You're not. It's not like the channels overloaded.
21:57
Hold on, I'm looking at this:
21:57
http://www.smop.co.uk/mediawiki/index.php/PXE_booting_floppy_images
21:58
<BGomes>
sbalneav: hi, how are u! :)
21:59
<sbalneav>
BGomes: I'm fine, yourself?
21:59
Databastard: Looks like that page seems to have some stuff you'll need.
21:59
Most of it will port across nicely to edubuntu. The dhcp server's the same.
21:59
<BGomes>
sbalneav: go back to working in ltsp5 on slackware on last week...
22:00
<Databastard>
This is where I get confused
22:00
<sbalneav>
Databastard: Since you're not using the dhcpd for booting ltsp, what you may want to do is mv /etc/ltsp/dhcpd.conf /etc/ltsp/notinusedhcpd.conf
22:00
<Databastard>
When I use kernel memdisk
22:01
<sbalneav>
then use their dhcpd.conf they provide in /etc/dhcp3/dhcpd.conf
22:01
<BGomes>
sbalneav: we have a progress now.
22:01
<Databastard>
When I use "kernel memdisk" the pXE boot halts and says that memdisk kernel not found
22:01
ah
22:01
<sbalneav>
BGomes: Ah, that's good news. You're using ldm and localdevices?
22:01
<Databastard>
So I need to change the dhcp.conf file
22:02
<sbalneav>
They have an example there you can tweak, at that web address I posted.
22:02
Looks like you'll also need to move /var/lib/tftpboot/ltsp out of the way, and set up the syslinux stuff they post there.
22:02
<BGomes>
sbalneav: we are makeing initrd.img for compatibli with slackware, localdevices woking fine, but ldm have many paths for working ( it next step)
22:03
<sbalneav>
Might need a bit of tweaking, but it looks relatively straightforward.
22:03
<Databastard>
okay
22:03
I'll go with that
22:03
thanks
22:03
<sbalneav>
sbalneav@phobos:~$ aptitude search syslinux
22:03
p syslinux - Bootloader for Linux/i386 using MS-DOS flo
22:03
Looks like syslinux is available in the package archives.
22:03
The writeup's for Debian, so it'll be fairly close of edubuntu.
22:04
BGomes: Congratulations!
22:04
<Databastard>
so I can install it with Synaptic?
22:04
<sbalneav>
BGomes: Got a web page for the project?
22:04
Databastard: Yep.
22:05
I guess the real question is: once you've got it working, what are you going to do with 200 usb boot floppies? :)
22:06
<BGomes>
sbalneav: now, use the wiki of my bussines, but we are to make the website project, in nexts weeks
22:06
<sbalneav>
Sounds awesome!
22:06
<Databastard>
Well, most of them will eventually be destroyed by our loaders :P

Al-Khouli: what u do it?
23:05
<Al-Khouli>
BGomes: sorry , i ddn't get u ??
23:06
<BGomes>
Al-Khouli: what u can read about of ltsp5 ?
23:07
<Al-Khouli>
BGomes: in fact i need this cz i am going to try a cluster over LTSP-5
23:07
<BGomes>
Al-Khouli: what is yout linux dist?
23:07
<Al-Khouli>
BGomes: edubuntu
23:08
<BGomes>
Al-Khouli: you need read of local apps, you can use cluster of edubuntu normal instalation
23:09
<Al-Khouli>
BGomes: i am initially thinking about openmosix
23:10
<BGomes>
Al-Khouli: if you can use cluster on edubuntu you can make some step on root-tree of ubuntu of ltsp5
23:10
<Al-Khouli>
BGomes: i am not sure where can i start from
23:10
<BGomes>
Al-Khouli: read more of edubuntu and openmosix, but openmosix dont woking in kernel 2.6
23:11
<Al-Khouli>
BGomes: what shall i go for then ? any other suggestions ?
23:12
<BGomes>
Al-Khouli: if you can to make cluster on edubuntu machine, you too to make on ltsp5 root-tree, no have diff of edubuntu and root-tree-ltsp5
23:13
Al-Khouli: use openssi for it
23:13
Al-Khouli: all it's possible on ltsp5
23:17
<Al-Khouli>
BGomes: Does this mean that openmosix is obsolete nowadays ?
23:18
<BGomes>
BGomes: yes... see on website project..
23:28
go out...
