04:59

hi :-)
05:23
morning
05:24zoro has joined #ltsp
05:26cdealer has joined #ltsp
05:26
<zoro>
I have a current setup of around 70 client machines, all running Windows 2000 (along with Office, FireFox, IE6 and a few other minor apps), and a Windows PDC running on a dual xeon with 2gigs of ram
05:27
i'm looking into the possibilty of using Edubuntu and LTSP to setup a network that can be expanded alot easier than what is there at the moment
05:27
<johnny>
zoro, it's kinda early atm :)
05:28
<zoro>
as its for a school, the major uses of the systems is basically just MS Office usage and web browsing
05:28
johnny: i know - i'll idle :p
05:28
<johnny>
migth have to wait for a bit :)
05:28
<zoro>
johnny: besides, it's 11:28am here in Dublin :D
05:28
<johnny>
sure but your question will prolly be lost in the shuffle
05:28
so you'll have to ask again :)
05:28
<zoro>
yup
05:28
i'm an idler-veteran :D
05:29
<PerfDave>
Whoo Dublin :)
05:29
<zoro>
still though, i've found that quiet times are good for getting answers too ;)
05:29
o/ PerfDave
05:29
<johnny>
zoro, many of the folks active in here are in the US
05:30
some even on the west coast
05:30
one of the most active ones is for sure
05:30* zoro sighs
05:30
<zoro>
:p
05:30
<PerfDave>
zoro: If you're desperate for MSOffice, you'll want to look into WINE or Crossover Office or something. Or just use OpenOffice.org, koffice or similar.
05:30
<zoro>
PerfDave: yeah i know about that already. i'm an ubuntu user myself so i use openoffice
05:31
honestly, the hardest part will be convincing the computers teacher in there that an LTSP would be useful for the school
05:31
so i want to make sure i've done all my homework and bring in a pre-setup server to demo the whole thing with him
05:31
<PerfDave>
zoro: One thing you might want to consider is setting up the LTSP server on a seperate machine to the PDC, then you can switch between your existing setup and LTSP just by choosing to boot off the HDDs or the NICs on the clients.
05:31
<johnny>
zoro, a good demo .. is virtualbox vm with server
05:31
and a couple clients :)
05:31
<zoro>
if he doesn't like it, fair enough, but i want to mke sure i do it right
05:32
<johnny>
that's how i test my clients atm
05:32
software wise
05:32* zoro nods
05:32
<johnny>
got ubuntu in a vm.. and another vm that does networkboot
05:32
works nicely
05:32
<PerfDave>
zoro: You could also have your LTSP server use the Windows Active Directory stuff for auth (and possibly even mounting home directories using Samba), to keep the systems compatiable during any transition period.
05:32
<johnny>
or fire the computer teacher :)
05:33
and hire a better one
05:33
<zoro>
hehe
05:33
<ogra>
geeez
05:33
<zoro>
he's actually my old teacher :) this is for the school i used to go to :D
05:34
<ogra>
http://afp.google.com/article/ALeqM5iU4Lq7tOR_WVOJLZ3IeRaIH03x6w
05:34
<zoro>
i'm their netadmin - and i want to make it as easy as possible for him to run, maintain and expand if i'm not around
05:34* PerfDave likes the idea of having LTSP supplement a Windows setup, work transparently with it, then slowly migrate :)
05:34* ogra needs to teach the gendarmes about ltsp :)))
05:34
<johnny>
ogra, !
05:34
welcome!
05:35
<ogra>
hey hey
05:35
<johnny>
still learnin the python
05:35
still hackin the sabayon :)
05:35
<ogra>
we should look into sabayon thins week ... i'd like to avoid to have to write an UVF exception :)
05:35
<johnny>
UVF ?
05:35
<ogra>
14th is feature freeze
05:35
upstream version freeze
05:36
(the freezes are the same this release due to its LTS nature
05:36
<johnny>
well upstream is already frozen :)
05:36
<PerfDave>
Oh, Sabayon's the Gentoo derivative, right?
05:36
<johnny>
no
05:36
well yes
05:36
but not what we're talking about
05:36
it's a user profile tool for gnome
05:36
<PerfDave>
Oh, right.
05:36
<zoro>
PerfDave: well, i'd rather just do a "Big Switch", and get them out of the hole they're digging themselves into
05:36
<johnny>
unfortunate naming conflict
05:36
<ogra>
johnny, that freeze is from ubuntu, meaning no new upstream versions after that point of the release schedule
05:37
<PerfDave>
zoro: You might, but you might find it easier (politically rather than technically) to add to what's there already and then switch back.
05:37
<ogra>
johnny, well, sabayon was there forst :P
05:37
*first
05:37
<johnny>
which one? :)
05:37
<ogra>
hehe
05:37
choose :P
05:37
<johnny>
as a gentoo user.. i decline to answer :)
05:38
next version will support xephyr..
05:38
but too late for this gnome release
05:38
<zoro>
PerfDave: Yeah I see your point, and its a valid one ;) In my case I have it pretty easy though - there's only 1 person to convince. The school doesn't care about technology - the teacher does. So if I can sway him in 1 sitting, I can just do it
05:40
<ogra>
oh i really love that article :)
05:40
"He also added that "the Linux interface is ahead of other operating systems currently on the market for professional use.""+
05:40
<johnny>
?
05:40
article?
05:40
<ogra>
johnny, the url i pasted above
05:40
http://afp.google.com/article/ALeqM5iU4Lq7tOR_WVOJLZ3IeRaIH03x6w
05:40
<johnny>
aha..
05:40
i didn't know what afp was :)
05:41
<ogra>
the whole french police switches 70000 desktops to ubuntu
05:41
<zoro>
that's a whole lot of money
05:42* johnny wonders if the canonical folks can handle this kinda workload :)
05:42* ogra wonders if they pay with desktops where zoro lives
05:42* ogra tries to imagine zoro's wallet
05:42
<zoro>
:)
05:42
<ogra>
johnny, the article doesnt say that they buy support at canonical :) (yet)
05:42
ubuntu != canonical :)
05:43
<johnny>
i meant both really
05:43
as in.. more user bug reports
05:43
more folks in the irc
05:43
etc
05:43
<ogra>
ah well, we'll manage another 70000
05:43
<johnny>
more servers for download
05:43
etc
05:43
i'd like to work for canonical some day..
05:43
<ogra>
its unlikely that all of them will show up on IRC or file bugs :)
05:43
<PerfDave>
zoro: But if you go for a complete replacement, and something goes wrong, you end up with an unusable IT system and you and he end up looking foolish and maybe getting into trouble.
05:44
<ogra>
johnny, all i can point you to is http://www.ubuntu.com/employment :)
05:44
<johnny>
i don't think i'm ready yet ..
05:44
<PerfDave>
Is it hard to get a job with Canonical?
05:44
They seem to hire everybody.
05:44
Or at least, to try to.
05:44
They're worse than Google ;)
05:44
zoro: You also need to make it as easy as possible for people to migrate. Letting them use their existing Windows domain accounts and file shares is a good way to do that.
05:45
<johnny>
i've been doing web devel for years, using gentoo, i'm just now playing wit debian/ubuntu since july
05:45
<ogra>
PerfDave, we try to hire th best :)
05:45
<johnny>
so now i'm more deeply learning autotools
05:45
<PerfDave>
ogra: That'll be why they haven't approached me then. Or perhaps that's because I don't use Ubuntu :)
05:45
<ogra>
(at least people with better grammar skills than me :P )
05:46
PerfDave, well, preferred are people that already worked with ay of the devs and have a recomendation through contributing ...
05:46
but indeed not all jobs can be filled like that
05:46
<PerfDave>
ogra: Yeah, I have no interest in contributing to Ubuntu :)
05:46
<zoro>
PerfDave: Yeah I understnd. Either way I can't do anything until I have an LTSP server setup for testing in my own environment, so I'll be getting onto that in the next few days. Thanks though :)

<Nubae>
hi there... I've got a question about using LTSP serving a fat chroot
07:52
I've got authentication working against an LDAP directory
07:53
but under Gutsy, the startup sequence hangs at starting system log daemon...
07:53
I believe this has to do with xorg
07:53
<PerfDave>
Why are you serving a FAT chroot?
07:54
<Nubae>
because I have a bunch of core 2 duo laptops with 2 gigs of ram
07:54
which are totally wasted otherwise
07:54
<PerfDave>
I'll guess that it has something to do with FAT not supporting Unix-style file permissions, and something hanging because of that.
07:55
<Nubae>
fat = fully installed edubuntu desktop chroot
07:55
not the file system
07:55
fat 'thin' client
07:55
<ogra>
Nubae, can you take out quiet and splash from the bootoptions ?
07:55
<PerfDave>
Ah, you should be more specific :)
07:55
<ogra>
it should reveal more info then
07:55
(in the pxe defaults file)
07:56
<Nubae>
ah, will do
07:56
<ogra>
also note that this setup will required some tweaks ... the ltsp-client scripts are likely interfering with a normal boot sequence here
07:57
but dropping splascreen and quiet should give you some hints
07:57
<Nubae>
yeah, I know I'm close though, this must have something to do with the xorg starting up part
07:57
everything else seems to be working allright, but let me give you the output
07:57
I've exported /home through nfs too, thats correct no?
07:58
<kysucix>
hi
07:58gonzaloaf has joined #ltsp
07:58
<kysucix>
I've got nfs timeout problems...
07:58
I tried with sleep 10 method, changing rsize or wsize but it doesn't work :(
07:59krishna has joined #ltsp
07:59
<kysucix>
the weird thing is that opening /bin/sh to the client and making the same command it works!
07:59
<Nubae>
well, went all the way through to login prompt
07:59
<kysucix>
do you have any suggestion? I'm totally lost
07:59
<Nubae>
but no X startup
07:59
<zoro>
.:13:52:28:. < Nubae> hi there... I've got a question about using LTSP serving a fat chroot
07:59
.:13:53:47:. < PerfDave> Why are you serving a FAT chroot?
07:59
.:13:55:23:. < Nubae> fat 'thin' client
07:59
brilliant
08:00
excellent misunderstanding :D
08:01
<Nubae>
yeah indeed
08:01
<PerfDave>
Stranger things have happened, I'm sure ;)
08:02
<Nubae>
ogra any ideas? startup goes through to login prompt, I can login there and startx from the command line
08:02
but no gnome
08:06
actually, when I login to the terminal, I get a message cannot find name for group ID such and such (2 times) and then a prompt that shows I have no name!@fatclient
08:06nicoAMG has quit IRC

<kysucix>
adding "-o retrans=10" to
08:06
/opt/ltsp/i386/usr/share/initramfs-tools/scripts/nfs solves nfs timeout problem
08:07
<Nubae>
I cannot unfortunately do a su root in the chroot, cause authentication fails, and trying to create a password for root in the chroot fails too
08:07gundul- has joined #ltsp
08:07
<gundul->
hello
08:07
i have problem in ltsp access local device
08:07
<Nubae>
result is I cant see the log files to see where its failing
08:07
<gundul->
anyone can help ?
08:07
<ogra>
Nubae, how do you try to set that pw ?
08:07
<Nubae>
passwd
08:08
<ogra>
it works fine here
08:08
<Nubae>
on a fat client?
08:08
<ogra>
sudo chroot /opt/ltsp/i386 passwd
08:08
then sudo ltsp-update-image
08:08
(which might take quite long with a whole desktop installed there) :)
08:08
<Nubae>
actually, doesnt... its quite fast
08:09
<zoro>
does it only send the differences?
08:09
<Nubae>
passwd: Authentication information cannot be recovered
08:09
passwd: password unchanged
08:09
<zoro>
or does it resend the entire desktop install?
08:09
<Nubae>
differences (I believe)
08:09
<zoro>
Nubae: have you kept a blog or anything of how you setup your ... well, setup?
08:10
<Nubae>
yeah, I'm writing it up in the ubuntu wiki
08:10
<zoro>
linkage \o/
08:10
<Nubae>
but... first I want to see X before I shout success
08:10* zoro nods
08:10
<zoro>
i'm just looking for reading at the moment anyway
08:10
looking to setup a rather large network using edubuntu myself
08:11
<Nubae>
zoro, well, I'm working on it at the moment, but wont publish until its fully functional
08:11
<ogra>
Nubae, gdm is installed i suppose
08:11
<Nubae>
should ahve been pulled in through apt-get installed edubuntu-desktop, no?
08:11
<ogra>
yes, usually
08:11
but re-check please
08:11
<Nubae>
well gdm at the command line does not work
08:11
<zoro>
Nubae: no problem. i'm looking forward to reading it
08:12
<ogra>
another thing is that X is configured by the ltsp-client-core initscript
08:12
might be that gdm tries to start before there is X configuration
08:12
(which actually shouldnt matter though with gutsys xorg)
08:12
<Nubae>
hmmm.... well, doing apt-get install gdm is pulling through a lot of crap
08:12
xfce stuff
08:13
<ogra>
huh ?
08:13
<gundul->
mm... anyone can help me with access local device ?
08:13
<ogra>
that sounds massively wrong
08:13
gundul-, not if you dont tell us the symptoms :)
08:14
<Nubae>
sorry :-/ me reading too fast... its under recommended packages that xfce stuff is mentioned
08:14
<gundul->
i plug usb drive in client, but it didn't seem to be automounted
08:14
<Nubae>
ok, what about the pam.d gdm file, should that have anything special to allow authentication from ldap?
08:15
<ogra>
gundul-, which distro and ltsp release ?
08:15
<Nubae>
ogra, is lts.conf looked at in any way by the fat system?
08:16
<gundul->
ltsp 4.2 and I use mandriva 2005
08:16
<ogra>
Nubae, ltsp-client-core uses it
08:16
gundul-, oh, thats ancient and unmaintained ...
08:16
<Nubae>
so yes then
08:16
<ogra>
look at the ltsp.org wiki, there migh be more info
08:16
i think there is a troubleshooting guide for 4.x localdev somewhere
08:17
<gundul->
which one is ancient ?
08:17
ltsp or mandriva ?
08:17
<Nubae>
should I edit the initscript?
08:17
both :-)
08:17
<ogra>
ltsp 4 wasnt touched for about three years
08:17
so newer HW wont work and rthere might be security holes
08:17
<gundul->
so i have to use this LTSP-5.0 ?
08:18
<ogra>
i fear there is no ltsp5 for mandriva ... i dont think anyone has put time into integration
08:18
ltsp5 requires the distributor to integrate it
08:18
so 4.x might be your best bet ... but people knowing the fixes and workarounds get rarae nowadays
08:19
Nubae, well, first you really need gdm installed ...
08:19
<gundul->
thank you
08:19
<Nubae>
it is
08:19
<ogra>
ok
08:19
and if you try to start it on a running client whats the error you get ?
08:19
look in xorg.6.log
08:19
or in any other log you find
08:20
<Nubae>
so u think the authentication error when trying to create the root pass is related to not having gdm installed?
08:20gonzaloaf has quit IRC
08:20
<ogra>
no
08:20
you should be able to set a password nn the chroot
08:20
<Nubae>
ok, this is what I get: passwd: Authentication information cannot be recovered
08:20
<cliebow_>
gundul-: i think localdev troubleshooting is on wiki.ltsp.org in 4.x
08:20
<ogra>

08:21mccann has joined #ltsp
08:21
<ogra>
mccann, hey
08:21
<Nubae>
I need the root pass or I cant see the ologs
08:21
<ogra>
sme movement going on in sshd :)
08:21
*some
08:21
<mccann>
ogra: yo
08:21
ogra: cool, like what?
08:21
<ogra>
cjwatson was just discussing his changes in #ubuntu-devel a minute ago :)
08:22
<Nubae>
well, I'll just rebuild the image and see if I can at least start gdm now
08:23gundul- has quit IRC
08:23
<Nubae>
just so you know, there is an error in the ltsp-update-image script...
08:23
I have to do this to get my image built: sudo ltsp-update-image -a fati386 -b /opt/ltsp -p 2003
08:24
really the fati386 should be here: -b /opt/ltsp/fati386 but that sets it up wrong
08:25
maybe my inability to create a passwd is related to ldap being used for authentication in the chroot?
08:26
<ogra>
mccann, see the bottom :) http://irclogs.ubuntu.com/2008/01/30/%23ubuntu-devel.html (last lines from 13:57 on)
08:26gundul- has joined #ltsp
08:26
<ogra>
hmm, thats not having everything yet
08:27
but it looks like he wants it in sshd directly
08:27
at least for ubuntu ...
08:27
<gundul->
how to insert mount command after usb drive detect ?
08:27
<ogra>
no idea how upstream sees that
08:28
<mccann>
ogra: you'd probably want each client to be on its own seat (just like we do for xdmcp)
08:29Daggett has joined #ltsp
08:29
<Nubae>
ok, nss_ldap is saying it cant bind to ldap server, invalid credentials... but on startup it did connect, whats going on here? (this is after doing gdm form the console)
08:30
<ogra>
mccann, right
08:32Blinny has joined #ltsp
08:32
<ogra>
Nubae, in gutsy you need to use ldap-auth-client or so to set it up ... did you do that ?
08:33gundul- has quit IRC
08:34
<Nubae>
yes
08:34
it wouldnt have come this far if it wasnt working
08:34
<ogra>
well, root shouldnt be handled by ldap though
08:34
<Nubae>
right, but now I'm talking about the gdm error above
08:34
<ogra>
at least *i* wouldnt do it like that :)
08:35
<Nubae>
where does gdm look at for authentication via ldap¿
08:35
?
08:35
<ogra>
gdm needs the gdm user in place
08:35
and runs as such
08:35
<Nubae>
yeah ok, so I add the user and group to ldap
08:37
gdm user exists in ldap already
08:37gonzaloaf has joined #ltsp
08:37
<ogra>
check /etc/passwd on the client :)
08:37
i be the user and group id's are broken then
08:37
*bet
08:38
system groups and users shouldnt come from ldap
08:38
<Nubae>
hmm... ok, so should I copy across the users and groups from the server to the chroot?
08:38
<ogra>
simply because usually packages create the system users ... during install there might be no ldap
08:38
(i.e. if you install in a chroot ;) )
08:39
<Nubae>
gotcha
08:39
<ogra>
i'd make everything below uid 1000 come from /etc/passwd ...
08:39
<Nubae>
indeed no gdm in /etc/passwd
08:39
<ogra>
from iud 100 upwards ubuntu creates normal user accounts
08:39
*1000
08:40
so you will still have a working system even if your ldap server ot the net is down
08:40
*or
08:40
<Nubae>
but the fat client needs to authenticate somehow
08:41
I'm only using ldap for the fat clients
08:41
fat 'thin' clients
08:41
<ogra>
yeah, make sure the order in nsswitch.conf is right so it first looks in passwd
08:41
<PerfDave>
ogra: All non-root accounts should come from LDAP!
08:42
<ogra>
then make soure to have no duplicatesd system users/greoups in ldap and passwd/group
08:42
PerfDave, that means a lot stuff wont work
08:42
as soon as your ldap is gone
08:42
<Nubae>
I have no gdm in /etc/passwd, should it be there?
08:42
<ogra>
udev needs the udev user to even create devices
08:42
you dont want that in ldap
08:43
<PerfDave>
Meh, just have a resilient LDAP setup :)
08:43
<ogra>
Nubae, well, the packages postinst should have created that
08:43
<Nubae>
didnt
08:43
<ogra>
bug
08:43
<Nubae>
the group is there, user isnt
08:43artista_frustrad has joined #ltsp
08:44
<ogra>
gdm:x:109:119:Gnome Display Manager:/var/lib/gdm:/bin/false
08:44
you should have something like that
08:45
(while the group is created dynamically ...)
08:45
so the numbering will differ
08:45
err
08:45
s/group/id/
08:45
<Nubae>
nope... not in /etc/group or /etc/passwd now I've checked properly
08:45
<PerfDave>
getent group | grep gdm
08:46
<ogra>
that doesnt help
08:46
getent will use ldap
08:46
<Nubae>
gdm:x:118:
08:46
indeed
08:46
comes from ldap
08:47
<ogra>
ogra@ceron:~/isos/hardy$ grep adduser /var/lib/dpkg/info/gdm.*
08:47
/var/lib/dpkg/info/gdm.postinst: adduser --system --ingroup gdm --home /var/lib/gdm gdm
08:47
/var/lib/gdm is likely owned by the wrong uid in your case
08:48
<Nubae>
gdm.gdm (how do I find the uid?)
08:49
<johnny>
id gdm
08:49
or look in /etc/passwd
08:49
<ogra>
its 118
08:50
you should do that chrooted :)
08:50
not in the running client that definately uses ldap ;)
08:50
<Nubae>
uid=108(gdm) gid=118(gdm) groups=118(gdm)
08:50
<ogra>
right
08:51
<Nubae>
but thats from ldap
08:51
<ogra>
first fix your nsswitch.conf
08:51
make sure it checks the local file first
08:51
make sure there are only system users in passwd/group locally
08:52
<Nubae>
ok, I've got ldap then files
08:52
<ogra>
then all your real users should come from ldap while system functionallity is provided by local system accounts
08:52
right, flip that order
08:52
files then ldap
08:52
<Nubae>
ok, done
08:53
so I remove system users from ldap?
08:53
<ogra>
yes
08:54
<Nubae>
every last one?
08:54
:-)
08:54
<ogra>
but only if you are sure they are in passwd :)
08:54
<Nubae>
they're not... gdm is only in ldap
08:54
<ogra>
ubuntu starts assigning non system users from uid 1000 on
08:54
look at everything with smaller uid
08:55
udev and messagebus for example come to ming
08:55
*mind
08:55
<Nubae>
ok, to be clear then, system users in ldap, but not in /etc/passwd should be copied to /etc/passwd?
08:55
<ogra>
not copied :)
08:55
you cant rely on the fact that your client has the matching UI free
08:56
<Nubae>
ok, copied and verify the UI is unique?
08:56
<ogra>
grep for the adduser command in /var/lib/dpkg/info/<packagename>.postinst
08:56
and use that
08:56
<Nubae>
ok do what the postinst would do... but shouldnt that be the same as the user created in ldap?
08:56
<ogra>
and make sure $HOME permissions match
08:57
well, you had ldap ordered first ...
08:57
it likely is
08:57
but double check that
08:57
<Nubae>
I mean, I'd imagine when I installed gdm, the user was created in ldap
08:57
ok
08:57
gotcha... btw.. this is far more complex than just apt-get install edubuntu-desktop ;-)
08:57
<ogra>
yeah
08:58
thast why i didnt add it as option to ltsp-build-client yet ;)
08:58
<Nubae>
heh, ok, well I'm documenting at putting in wiki.ubuntu.com
08:58
<ogra>
if we have a proper ldap setup that works without any manual setup i'll consider it ...
08:58
<Nubae>
ldap is pretty easy now
08:58
<ogra>
currently i think fedorea will be ahead once they have ltsp5 in ... they simply have the auth-server bits we're missing in ubuntu
08:59
its easy, on the client side
08:59
<Nubae>
server side too
08:59
<ogra>
but not at all on the server side
08:59
<Nubae>
if you dont do ssl or tls
08:59
I set it up in about 20 minutes
09:00
<ogra>
and my expectation of calling ltsp-build-client --fat is that you dont have to do anything beyond
09:00
as long as we cant provide that with distro tools in ubuntu i wont add that feature
09:00
<Nubae>
well, the smbldap-installer works too
09:00
for setting up the server
09:01
and then just migrate-unix-accounts

I have a diff comparison of two very long nearly-identical single lines (30k+ each) -- is there an easy way to ignore the 99% common stuff and only print part of the lines that are actually different? I was thinking of sed'ing spaces into newlines if there isn't a native diff method.
09:08

who the heck writes 30k+ long lines ?
09:08

Yeah. Output of a javascript

jeez, so I have to wade through the postinst of every package that creates users in the thin client?
09:14
well, calling it a day I'm gonna tackle this tomorrow on a clear head
09:14
thanks for the help ogra
09:16
<ogra>
Nubae, well, the right approach would have been to have your install done in the chroot and *then* set up ldap
09:16
so all system users would have the proper setup
09:17
i wonder if its not easier to actually re-run ltsp-build_client and install the desktop than to wade through the users
09:18
<Nubae>
i thought it was done, didnt realise gdm wasnt installed alongside edubuntu-desktop

11:37
the root-path is valid, but the filename /ltsp/pxeliux.0 is not

well where shold /ltsp/pxelinux.0 be ?
11:43
should I have a pxelinux.0 on my system ?
11:43
<PerfDave>
Your DHCP server needs to tell the client to load a kernel via TFTP. The pxelinux.0 should be on the LTSP server.
11:44
<some_dude>
I'm not finding it on my system at all
11:44
<ogra>
/ltsp/pxelinux.0 should be under the root of your tftp server
11:44
what distro ?
11:44
<some_dude>
and that should be in my /opt/ltsp/i386 ?
11:44
ubuntu
11:44

no

under 7var7lib/tftpboot then

hello
11:49
how can i force acpi in ltsp
11:49krishna has joined #ltsp
11:49
<ogra>
some_dude, you need to run ltsp-update-kernels to create that dir properly
11:50
bartolomeojsimps, you mean use the kernel commandline option acpi=force ?
11:50
<bartolomeojsimps>
yes
11:50

depends on your distro and ltsp version
11:50
<bartolomeojsimps>
ubuntu 7.04
11:50
ltsp 5
11:50

add it to /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

you didnt talk about any error :)
12:03
<bartolomeojsimps>
acpi: bios age (1997) fails cutoff
12:04
the las line is
12:04
IP-Config: eth0 hardware address ----- DHCP RARP
12:04
<ogra>
the acpi message shouldnt prevent you from booting at all
12:05
it just means the system wont use acpi because the bios is to old
12:05
the ubuntu kernel should actually fall back to use the apm module for such HW silently
12:06
what kind of HW is that exactly ?
12:06
<bartolomeojsimps>
amd k6-2 500 mhz
12:06
pcchips 598lmr
12:06
<ogra>
how much ram
12:06
<bartolomeojsimps>
256 mb
12:06
<ogra>
hmm, that should all be fine
12:07
<bartolomeojsimps>
in the las t days i activate local_apps in lts.conf
12:07
but yestreday i quit that line
12:07
<ogra>
there is no localapps support in ltsp5
12:07
and its unlikely to be there before 8.10
12:09
it sounds very much to me that your network card cant be configured right ... you should see a MAC address in that IP-Config line
12:09
<bartolomeojsimps>
yes
12:09
00:e0:06:ee:be:6d
12:10
it happens only in my amd k6 2 based pcs
12:10

hmm
12:10

but they werw working fine
12:10
<ogra>
so since when dont they work anymore
12:10
<bartolomeojsimps>
yes
12:10
<ogra>
you must have changed something then
12:11
find out what that was and change it back :)
12:12
<bartolomeojsimps>
i have touch the lts.conf and i have copy some files from /usr/lib to /opt/ltsp/i386/usr/lib in order to run local apps
12:12
could that be the problem?
12:13
<ogra>
yes
12:13
<bartolomeojsimps>
the strange thing is that my other machines works well
12:13DonSilver has quit IRC
12:13
<ogra>
try to change back what you did
12:13
there is no easy way to run localapps atm ...
12:14
if you want to fiddle with it: sudo ltsp-build-client --chroot testing
12:14
<bartolomeojsimps>
how i know that the files i copy wereĊ„t ther before?
12:14
<ogra>
then you can play around in the testing chroot without doing harm to your actual setup
12:14DonSilver has joined #ltsp
12:15
<ogra>
bartolomeojsimps, well, didnt you look before you copied stuff over existing files ?
12:15
i'd alwas do a backup of files before copying something just over them
12:15
*always
12:16
<bartolomeojsimps>
i did it with sudo, so it didn't ask me confirmation
12:16
am i right?
12:16
<ogra>
indeed
12:16
it expects that you know what youre doing if you use sudo and gain administrative rights
12:17
<bartolomeojsimps>
what if i remove those files, after doing a backup
12:17
<ogra>
one thing you can do is: sudo mv /opt/ltsp/i386 /opt/ltsp/i386.old
12:17
and get a clean client setup with: sudo ltsp-build-client
12:17
that will recreate everything under /opt/ltsp/i386
12:18
before making any changes make a tar archive of that dir ... so you can always play it back
12:18
<bartolomeojsimps>
what info i lose if i do taht
12:18
that
12:19
<ogra>
depends what you already changed in your chroot
12:19
<bartolomeojsimps>
i don't understand, pleas explain me
12:19
<ogra>
you lose only stuff you manually changed in /opt/ltsp/i386
12:22

well, why do you blindly copy files around on a production system ?

how can i know the defalut files that were in the /opt/ltsp/i386/usr/lib directory?
12:26
<ogra>
kysucix, vagrantc can answer that
12:27
bartolomeojsimps, only idf you build a fresh chroot with ltsp-build-client else you cant compare
12:28
<bartolomeojsimps>
can i do it in a testing dir?
12:28
<kysucix>
vagrantc, is unionfs usable with debian ?
12:28
<ogra>
bartolomeojsimps, thats what i said above
12:28
see the command i wrote there
12:28
<bartolomeojsimps>
sudo ltsp-build-client --chroot testing
12:29

kysucix, generally it should work (works in ubuntu since 8 months now) but i dont know the status of the kernel module in debian atm

bartolomeojsimps, exactly
12:29
kysucix, and indeed sid only :)
12:32
<vagrantc>
kysucix: it was working in sid a little while back, but then initramfs-tools dropped "grep" and "tr" from the default... so we either have to re-write the initramfs-tools bits that enable nbd+squashfs+unionfs, or manually add grep and tr to the initramfs
12:32
<kysucix>
ok
12:32
<vagrantc>
but the unionfs part of it was working as of a couple months ago
12:34daya has quit IRC

12:34
we still have grep and tr ... i'm 100% sure

ogra: you haven't synced initramfs-tools with debian since edgy, i don't think
12:36

no
12:36
well, we cherrypicked patches afaik
12:36
<vagrantc>
yes
12:36
<ogra>
the nfsroot one is in since gutsy
12:36
but i dont think there is much interest in most of the debian changes
12:37
especially since there is a ton of new stuff being done in ubuntu for hardy atm i dont think they plan to break it by mergeing :)
12:37
the new error handling will be such a relief
12:38
proper messages instead of dumb busybox propmpts without any indicatior
12:38
<vagrantc>
i think maks wanted to get it down to just klibc-utils, and drop anything depending on glibc

I'm putting some lines in /var/lib/tftpboot/i386/lts.conf for testing purposes (X_COLOR_DEPTH=8) and they don't seem to be taking. Is there a log file or something I can check to see what the issue is?
14:09
This is LTSP5 on 7.10

14:42

<vagrantc>
warren: i have patches to ldm's rc.d support to allow /etc/ldm/rc.d, @libexec@/ldm/rc.d and /usr/share/ldm/rc.d simultaneously
14:50
<warren>
what is ldm's rc.d for?
14:50* warren didn't get ldm to actually work on fedora yet
14:51
<vagrantc>
warren: it's where ltspfs hooks get plugged in ... basically scripts that are run at login and potentially logout

warren: i think the patches add a couple more filesystem calls, but overall shouldn't be too harsh of a performance cost, for full backwards compatibility and future compatibility, and gives the sysadmin the ability to override a plugin
14:55
ogra: any thoughts on that?
14:55
<reh>
so

hrhr

<vagrantc>
mcfloppy: what linux distro?
14:56
<mcfloppy>
i use debian last stable ;)
14:56
ltsp5
14:56
and want to run pulseaudio
14:56
<vagrantc>
using the ltsp backports?
14:57
<mcfloppy>
ii ltsp-server 5.0.31debian2~0.etch.1 basic LTSP server environment
14:57
ii ltsp-server-standalone 5.0.31debian2~0.etch.1 complete LTSP server environment
14:57
<vagrantc>
ah, those are quite old.
14:57
i would recommend upgrading and rebuilding your ltsp environment
14:57
<mcfloppy>
should i upgrade?
14:57
ok
14:58
<vagrantc>
!debian
14:58
<ltspbot>
vagrantc: "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
14:58
<vagrantc>
mcfloppy: there should be a howto
14:58
<mcfloppy>
http://wiki.ltsp.org/twiki/bin/view/Ltsp/Ltsp5 this?
14:59
<vagrantc>
mcfloppy: http://wiki.debian.org/LTSP/Howto
14:59
<mcfloppy>
yes i see
15:01
should i use the apt version or the backported?
15:01
<vagrantc>
apt version?
15:01
<mcfloppy>
ah ok.. i must take the backport
15:02
If you want to use newer LTSP related packages (with ltspfs and pulseaudio sound):.....
15:02
<vagrantc>
to get support for pulseaudio, i would recommend following the instructions for the backport
15:02
<mcfloppy>
;)
15:16
damn job :p

back
16:09
so..... i have a new problem :)
16:10
i dont know how to install the binary nvidia driver on my new backport ltsp5
16:10
i cant remind how i did it the last time
16:11
<vagrantc>
the same way you would on a system with a harddisk
16:11
with one difference ...
16:11
chroot /opt/ltsp/i386
16:11
and then run all your commands
16:11
like apt-get install xserver-xorg-video-nvidia-evil-proprietary-driver
16:12
<mcfloppy_>
ok
16:15
hmmm
16:15
nvidia has its own installer
16:16
<PerfDave>
mcfloppy_: nvidia's install script tends to crap all over distribution files though. Most distributions have specific ways for installing the proprietary driver, and they're best followed.
16:18
<mcfloppy_>
hmm
16:18
ok

17:16
<mcfloppy_>
hehe
17:16

17:17
install the same kernel on the server and reboot.... then i can compile my nvidiakernel in chroot ^^
