is there a way to resume a failed ltsp-build-client on *buntu ?
04:22
it seems to download a topn of files and I was wondering where it stored those files so I can keep them so thye dont need to be downloaded again ?
04:23
does it not access the local apt archives cache ?
04:23estong_ has joined #ltsp
04:23
<vagrantc>
/opt/ltsp/i386/var/cache/apt/archives
04:23
dean_za: but you would have to modify the script that checks if there's already a directory present, and blow that away.
04:23
well ...
04:24
you would have to modify the script that checks for the presence of a directory, as it will not proceed if the directory already exists.
04:25
<dean_za>
doeas it create it as soon as it starts ?
04:25
i could rsync the contents back in hile it was running
04:25
would save me some time
04:25
<vagrantc>
easier just to disble the check ...
04:26
<estong_>
ltsp5 now running on my etch server but "mount failed error" occurs at times.
04:26
nfs-kernel-server restart seems to address it.
04:26
is this a bug?
04:27marek82_ is now known as marek82

<vagrantc>
dean_za: copy /usr/share/ltsp/plugins/ltsp-build-client/common/020-rootpath to /etc/ltsp/plugins/ltsp-build-client/020-rootpath
04:28
dean_za: exit it and comment out the "exit 0" line
04:28
dean_za: but then you have to make sure everything *but* the packages are deleted
04:29
estong_: when exactly do you get the error message ? can you consistantly reproduce it ?
04:29
<estong_>
after reboot.
04:30
<vagrantc>
estong_: what happens after rebooting what?
04:31
estong_: please be specific. it really speeds up the process for everybody.
04:31
<estong_>
when i reboot the ltsp5 server, the thinclients give the mount failed error when i boot them
04:31
i use pxe booting
04:31
<vagrantc>
estong_: do they eventually suceed? or only after you restart nfs ?
04:32
<estong_>
only when i do the nfs-kernel-server restart
04:32
<vagrantc>
estong_: is nfs running at all before you restart it ?
04:33
<estong_>
yes
04:33
i checked it with exportfs
04:33
<vagrantc>
estong_: can you mount it from the server ?
04:33
estong_: i.e. mount 127.0.0.1:/opt/ltsp/i386 /mnt
04:33
<estong_>
that i haven't tried doing manually
04:33
i will try
04:34
mount: 127.0.0.1:/opt/ltsp/i386 failed, reason given by server: Permission denied
04:35

estong_: grep ltsp /etc/exports

<meeri>
hi folks
04:38
<vagrantc>
estong_: ps aux | egrep portmap
04:39
<meeri>
I´m having some problems wioth the 4.2 version
04:39
<estong_>
daemon 2511 0.0 0.0 1684 372 ? Ss 17:27 0:00 /sbin/portmap

root 3366 0.0 0.0 2852 712 pts/0 R+ 17:37 0:00 grep -E portmap
04:40
<meeri>
The first one is, i´m booting and geeting this error "exec of init (/sbin/init)failed!!!: 2--Kernel panic-not syncing,...
04:41
<vagrantc>
estong_: not sure what else to check ... and it just starts working if you restart it?
04:41
<estong_>
yes.
04:43
is automating the restarting of the nfs-kernel-server command a possible quick fix?
04:43
<meeri>
forget it guys, prob is fixed
04:43
<vagrantc>
estong_: ugly, but if it works for you ...
04:43
<estong_>
any suggestion on how i can do that?
04:44
<vagrantc>
estong_: you'll have to play around with it ...
04:44
<estong_>
ok.
04:44
<vagrantc>
estong_: do you have ltsp-utils installed ? if so, that might be causing problems.
04:44
<estong_>
yes. i think it is in there.
04:44
<vagrantc>
as the ltsp5 and ltsp 4.x stuff is largely incompatible
04:45
<estong_>
so ltsp5 does not need it?
04:47
<vagrantc>
nope
04:48
in fact, if you run it, it has often caused lots of problems for people.
04:48
<estong_>
ops! i checked, ltsp-utils is not installed.
04:48
<vagrantc>
post-etch, we actually conflict with it
04:50
<estong_>
so, is it a bug? or, am i the only one having this kind of issue?
04:52
<vagrantc>
first i've heard of it ...
04:53
estong_: is the ltsp line the only line in /etc/exports (other than commented lines)
04:54Q-FUNK has joined #ltsp
04:54
<estong_>
yes
04:54
and exportfs give me: /opt/ltsp <world>
04:55
<vagrantc>
what manual configuration have you done ?
04:56
<estong_>
>
04:56
?
04:56
<vagrantc>
how did /etc/exports get configured, dhcpd, etc ...
04:56
did you run ltsp-build-client ?
04:56
what's in /opt/ltsp
04:57
<estong_>
dhcpd.conf - i did that
04:57
ltsp-build-client - i ran that
04:58
/opt/ltsp has the i386 folder
04:58
<vagrantc>
hmmm...
04:58
perplexing.
04:58
<estong_>
may be the logs can tell something. and, what about inetd?
04:59
the order by which services should be running
04:59
<vagrantc>
grep filename /etc/*/dhcpd.conf
05:00
inetd just runs tftp typically ...
05:00
if output is really long, please use the pastebot:
05:00
!pastebot
05:00
<ltspbot>
vagrantc: "pastebot" is The LTSP pastebot is at http://pastebot.ltsp.org. Please paste all text longer than a line or two to the pastebot, as it helps to reduce traffic in the channel. A link to the content will be pasted in the channel.
05:00
<estong_>
filename "/var/lib/tftpboot/ltsp/i386/pxelinux.0";
05:01
<vagrantc>
ok, that looks good
05:01
<estong_>
just 1 line coz i commented the nbi.img
05:01
<vagrantc>
so, nfs-kernel-server is broken... restarting it manually fixes it ... gah.
05:01
<estong_>
ha ha ha
05:01
i wonder if i can delegate the task to the students
05:02
for now i can only restart it as root
05:02
and i am the only root.
05:02
<vagrantc>
only thing i can think of is that somehow your init scripts got re-ordered so that nfs-kernel-server is starting before some of the other needed services
05:02
but the defaults should just work fine
05:03
<cyberorg>
vagrantc: hi there, where can i find your three line delayed_mounter replacement changes?
05:03
<vagrantc>
cyberorg: i'm not away of such changes

05:04
<cyberorg>
hmm, i thought you made some changes in init scripts, must be one of the other devs
05:04
<envite>
Hello all from Spain
05:05
<estong_>
is this recommended "pkg-ltsp.alioth.debian.org", using newer ltsp files may just address the issue.
05:06
<vagrantc>
estong_: it's not going to fix anything with your broken NFS
05:06
<estong_>
ok
05:06
<vagrantc>
estong_: but i'd be happy if you tried the newer packages :)
05:07
<estong_>
i anticipate that u wud say that. i'll tell u more later. :)
05:07
<vagrantc>
i haven't yet tried the 5.0.8debian2 version on etch, but it should be very nice :)
05:13
<estong_>
ok. bye all for now.
05:13estong_ has left #ltsp

with ltsp4.2 setting SCREEN_01 = "rdesktop" in lts.conf gave me rdesktop, but there is no screen.d/rdesktop in ltsp5, like in ltsp4.2. pointers welcome.

vagrantc: i have another small problem on a different instalation , the thin client boots , gets to the login screen and then when i tr login its looks to be authenticating and then just goes back to the login screen
05:36
where can i look to see what the problem is
05:39
<seveneleven>
Does anybody know how to get work sound on a K6.ltsp terminalclient ?
05:41
<cliebow>
klausade, you can look that rdesktop screen script over..see if there is anything 4.2 specific in iot..Gadi would know..
05:42
<klausade>
cliebow: from a quick look it looks rather 4.2 specific, but i'm no expert, so I thought I'd ask you guys. I can't be the only one asking this?

i keep forgetting to merge them

05:45
<klausade>
vagrantc: I have a school (sadly) moving away from Skolelinux&ltsp, over to windows terminalserver. They will use ltsp (4.2 or 5) together with rdesktop.
05:46
<vagrantc>
for shame.
05:47
<klausade>
vagrantc: yes, but next year we just remove rdesktop and replace it with ldm or xdmcp :-)
05:47
<cliebow>
klausade, waait til Gadi comes in..though he may be in bethel this week
05:47
<vagrantc>
klausade: so... you're moving to windows terminalserver ... only to move back the following year ?
05:47
klausade: or you just suspect that's what will happen :)

hi everybody

I have no /dev(dsp

i got ltsp 5 running
05:50
<envite>
/dev/dsp
05:51

but i would like to set up local apps
05:51
can someone help me

<iverson_3333>
my aim is firefox + flash running locally
05:51
<vagrantc>
iverson_3333: unfortunately, you're on your own at this point
05:51
<seveneleven>
envite: dev/dsp ?
05:51
<vagrantc>
iverson_3333: there's no built-in support for local apps on LTSP5 yet
05:51
<envite>
seveneleven: yes, I have the module loaded but no /dev/dsp in the client
05:52muh2000_ has joined #ltsp

@vagrantc but can i use it on ltsp 4?
05:52
<vagrantc>
!localapps
05:52
<ltspbot>
vagrantc: Error: "localapps" is not a valid command.
05:52
<seveneleven>
envite: just a moment I'm checking it on my system right here
05:52
<vagrantc>
iverson_3333: search on wiki.ltsp.org for local app support for ltsp 4.x ...
05:52
<envite>
seveneleven: thx
05:53
<iverson_3333>
what??
05:53
so it works on ltsp 4
05:53
??
05:53
<vagrantc>
well, it's not *easy*
05:53
it would probably be easier on LTSP5 at this point, but it's still a fair amount of work.
05:54
<iverson_3333>
but do someone succeeded in running firefox and flash locally?
05:54
<vagrantc>
you need to set up some sort of network authentication, mount home directories, and well... i guess that's it.
05:54
oh
05:54
and you need to figure out a way for the server to know you want it to run locally
05:54
<iverson_3333>
but dows it work on ltsp 4.2?
05:55
<vagrantc>
iverson_3333: if all you want to run is firefox + flash locally, that is easy. but if you want some things running on the server and some things running on the client, that's hard.
05:55
<iverson_3333>
i need ltsp but firefox and flash to be processed by rthe clien cpu
05:55
i need ltsp but firefox and flash to be processed by the client cpu
05:56
<vagrantc>
well, you can run everything on the client CPU, but use LTSP instead of installed hard disks....
05:56
at any rate, it's going to require some work on your part.
05:56
it's not supported out of the box.
05:58Q-FUNK has quit IRC
05:59
<vagrantc>
iverson_3333: the short answer is, it's possible to do what you want to do, but it's not going to be easy.
06:01
<ogra>
wow, scott's really made it, ldm2 rocks
06:02
<klausade>
vagrantc: I suspect they will not be happy with windows terminalserver, and since the swicth back to linux will be short and quick ....
06:02
<vagrantc>
klausade: ah, good. :)
06:03
ogra: his commit messages are ... *too* cute. :)
06:03
<ogra>
heh
06:03
vagrantc, did you try todays ldm2 ?
06:03
i just added reboot and shutdown and fixed autologin
06:04
<vagrantc>

oops
06:04
<seveneleven>
envite: How did you check it ?
06:04
<ogra>
if we got that and ldminfod integration for session and lang, we're done
06:04
<vagrantc>
ogra: passed through security review yet?
06:05
<ogra>
well, done in the sense of, we have what we had before but way faster and more beautiful
06:05
nah#
06:05
<vagrantc>
heh
06:05
<ogra>
we have to go through the code anyway first
06:05
<envite>
seveneleven: I entered in the client console and ls /dev/dsp
06:05
<ogra>
i'd like to switch as much as we can to glib
06:05
<envite>
and there were no /dev/dsp
06:05muh2000__ has joined #ltsp
06:05
<envite>
but I think I've found the problem, let me check
06:05
<ogra>
that prevents somewhat from the worst
06:06muh2000_ has quit IRC
06:06
<ogra>
scott's using functions like fgets, popen etc ... that wont pass any ubuntu security review
06:08
in any case its a big improvement
06:09
<envite>
seveneleven: I found it
06:10
I used snd-via82xx as suggested in wiki, but now I changed to via82cxxx_audio and it worked
06:10
<seveneleven>
envite: I've checked it here on my machine (client) it's here. Also I've checked it on the server. The same result.
06:13
envite: Your glad. the sound on my client won't work :(. I don't know why.
06:13

<jammcq>
ogra: wow, looks like you are making some great progress
06:25
<ogra>
jammcq, 44.24 in the second run
06:25
i think thats it :)
06:25
<jammcq>
when you say 'x configuration' is that the new xorg autoconf? or the old style building of the xorg.conf file?
06:26
<ogra>
indeed the e2300 will be slower, but my squashfs stuff with scotties ldm2 seem to have done it
06:26
<jammcq>
did you get past the problems with ldm2 from yesterday?
06:26
<ogra>
when i say x configuration i mean i let it configure X the old way
06:26
<jammcq>
ah
06:26
<ogra>
like we always did
06:26
<jammcq>
cool
06:26
<ogra>
i'm pondering a new way here
06:27
<jammcq>
so, without the x-configuration, you are relying on xorg's auto-conf?
06:27
or are you providing a custom xorg.conf file?
06:27
<ogra>
Xorg -configure produces wonderful files to run sed on :)
06:27
autoconf
06:27
<jammcq>
suweeeeeeet
06:27
<ogra>
ltsp-build-client removes xorg.conf completely from the chroot
06:27meeri has joined #ltsp
06:27
<ogra>
if you dont run the configurator there is no file :)
06:28
one issue is left here, somehow the fbdev doesnt get freed so respawning doesnt work yet
06:28
but i guess thats an easy one
06:28
<jammcq>
is ldm2 fixed?
06:29
<ogra>
most of it, yes
06:29
<jammcq>
cool
06:29
so scotty found the problem from yesterday?
06:29
<ogra>
i just added the reboot and shutdown functions
06:29
and fixe the autologin stuff
06:29
that works as well now
06:29

jammcq, works now but I cant shutdown the client only logoff or standby
06:46
<jammcq>
hit the power button
06:46
that's all you need
06:46
<meeri>
is it possible to generate a shutdown script and include a desktop shortcut by default
06:47
<jammcq>
hmm, probably, but it's not included in ltsp right now. LTSP-5 has such capability, but that's only available in Ubuntu and Debian at the moment
06:48
<meeri>
ok, just press the shutdown button
06:48
<jammcq>
yep. you might need to hold the button in for 5 seconds or so

kk, one last question, I´m having various clients here, and the really new ones ( ab 1 year) are making probs: could not automatically detect the NIC, it´s an Asus A8N-Vm motherboard with the nforce410 chipset, are there any drivers out there
06:51subir has quit IRC
06:51
<jammcq>
I think the driver is there, it's just not auto-detecting it
06:51
the driver is called 'forcedeth' I think
06:52
you may need to pass 'NIC=forcedeth' on the kernel command line
06:52
http://wiki.ltsp.org/twiki/bin/view/Ltsp/KernelOptions
06:52
check that article for info on how to do that
06:54
<meeri>
yeah i know the 128 and 129 option, thx for the name, is there a site listed with all the kernel argument names
06:54
<jammcq>
no, not 128/129
06:54
you are probably using PXE for that
06:54
so that's different
06:54
and I don't know of a list of kernel args

is there support for plain etherboot clients in ltsp5? all howto's point to configuring PXE clients.
07:55vykarian has joined #ltsp

<vykarian>
hi guys.. I'm having some problem with PXE boots.. the DHCP gets the DHCPDISCOVER and DHCPOFFER but not the DHCPACK.. after about 20 minutos of try thats go..
07:56
does someone can help on that?

08:05
<vykarian>
fgiraldeau http://pastebin.ca/576317
08:05
like that.. that keeps looping
08:06
<fgiraldeau>
Biz. Try : tcpdump -i eth0
08:07
Only to see what packets are beeing transferd
08:07
<vykarian>
and after a few minutes that get the DHCPACK packet and boot-up normally
08:07
that only works with ASUS mobos with PXE boot
08:08meeri has quit IRC

Are you saying that it works well with one computer but not another?
08:09meeri has joined #ltsp

kinda..
08:09
thats a hibrid network
08:09
with some PXE and others etherboots
08:10
this error only occur sometimes (early in the morning) with the PXE clients
08:10
and started to occur a week ago
08:10
before that everything ran 100% by a month
08:11
<jammcq>
any chance there is another dhcp server on your network?
08:11
that's what it sounds like to me
08:11
maybe a router or another pc or something
08:12
<vykarian>
hmm..
08:12
that's a remote office
08:13
do u know a way/chance to check that through tcpdump?

meeri, how much ram is in your clients ?
08:30
<meeri>
uhhm, 64mb
08:31
<ogra>
which ltsp version and distro ?
08:31
<meeri>
4.2, fedora C6
08:31
<ogra>
that should suffice normally ...
08:32
64M is good for all ltsp versions ...
08:32
<meeri>
hm, the home dir is /home/username
08:32
<ogra>
do you have any flash sites open while that happens or so ?
08:32
<meeri>
no
08:33

did you check if it also happens if you log in directly on the server with that user ?

ok
10:25
I see him on this channel
10:25
but he's probably busy
10:25
<cliebow_>
he has it on all the time..takes about three days just to say hello to him
10:25
<john_s>
ooooh
10:25
all right
10:25
well I'll just muddle along then
10:26
<cliebow_>
you trying his installer?
10:26
<john_s>
I think I will.
10:26
It's hard to tell from the documentation if its what I want
10:27
<cliebow_>
sure..it is pretty simple to make a cvs and add users
10:27
<john_s>
but I guess I'll find out
10:27
<cliebow_>
do you need better containers?
10:27
<john_s>
well that's good
10:27muh2000_ has quit IRC
10:27
<john_s>
Well the deal is my users are created in active dirctory
10:27
and I am not able to make it go away yet
10:27
so I am using winbind
10:27
for the ltsp stuff
10:28
now I am scaling the ltsp server and putting a backend file store in another location
10:28
but everyone still needs the same uid/gid maps
10:28
<Guaraldo>
sbalneav: Pasted... did you read?
10:28
<cliebow_>
ldap is the way to fly..
10:28
<john_s>
yeah
10:28
<cliebow_>
we have three independent servers//files..ldap..ltsp
10:28
all auth to ldap
10:29
<john_s>
did you ever migrate from AD or did you start fresh with LDAP
10:29
<cliebow_>
yes..i used winbind for three yearsd
10:29
<john_s>
I don't want another domain right now, just a file server and serveral LTSP servers that can share ldap
10:29
<cliebow_>
but it was built brand new
10:29
<john_s>
so did you migrate users and their files?
10:30
<cliebow_>
yes to their files
10:30
for the who;le district...6 schools
10:30
<john_s>
yes
10:30
that is essentially what I am trying to do
10:30
3 schools
10:30
1500 users
10:31
<cliebow_>
about the same as me then..working flawlessly for me
10:31
<john_s>
well good.
10:31
<cliebow_>
i wrote a shelll script to set up the skeleton
10:31
<john_s>
elaborate please
10:31
<cliebow_>
so staff would esch belong to their school..and students by year of graduation
10:32
<john_s>
good. That sounds like what I want to do
10:32
<cliebow_>
ill send you a copy of the script if you like..ubuntu? or fedoira?
10:32
<john_s>
ubuntu
10:32
<cliebow_>
the only difference id the first entry
10:32
<john_s>
that would be great
10:32
<cliebow_>
k..give me a sec
10:32
<john_s>
is this migration process spelled out anywhere?
10:33
I've looked at the LTSP wiki, SAMBA docs, etc and everything looks partial
10:34
<cliebow_>
john_s:i dont thin there is anything hardcoded in there for my school..keep it under your hat if there is
10:34
sent
10:34
<john_s>
Thanks I just got it.
10:35
<cliebow_>
then we can talk about what pices do if you need it
10:35
<john_s>
I just read your previous email as well
10:35
ok
10:35
<cliebow_>
s/pices/pieces
10:35
<john_s>
I think you are right about containers
10:35
I do want some depth
10:35
<cliebow_>
yuo'll see ldifs made to set them up in therte..
10:35
<john_s>
like /home/domain/2005, /home/domain/2006
10:35
etc
10:35
thanks
10:35
very much!
10:36
<cliebow_>
ill be around..
10:36
<john_s>
ok, I'll read through this
10:40
cliebow this looks like it adds the samba schema to ldap
10:40
do I read that correctly?
10:40
among other things of course
10:41
<cliebow_>
umm..it builds an smb.conf
10:41
oh yeah..samba.schema is usualyy buried in the depths
10:41
until; you go get it
10:41
<john_s>
ok
10:42
so that part you have automated
10:42
?
10:42
<wpgmb>
guys: out of curiousity... where are those schools you're talking about?
10:42
<cliebow_>
Maine
10:42
<wpgmb>
How
10:42
<john_s>
Vashon Island SD
10:42
<wpgmb>
How'd you convince schoolboards to "leave" MS in favor of LTSP?
10:43
<john_s>
Well its considered a cost saving measure mostly
10:44
also will add bells and whistles that we have't set up for MS
10:44
<cliebow_>
Money!
10:44
i had a foreward thinking tech director
10:44
<wpgmb>
still... *tips his hat* .. well done!
10:44
<john_s>
same here
10:45

cliebow, it looks like this makes your samba server a pdc
10:47
is that correct?
10:47
preferred master=yes
10:47
domain master=yes
10:47
I assume that I can leave that commented out
10:48
and it will still automagically do the rest
10:48
<cliebow_>
errr..not sure..you can have three or four pdc on a network if you like
10:49
<john_s>
interesting.
10:49
What I don't want to do is offer other domains
10:49
because I don't want to have to join computers to it etc
10:49
I just want file sharing for those still on xp
10:49
sorry, I am just reading and asking questions as I go. I'll stop that and read
10:50
I appreciate this very much. Very impressive!
10:50
<cliebow_>
you wont have to join linuxboxes to the domain..just windersboxen
10:51
<john_s>
yes. But I don't want to do that
10:51
if i can avoid it
10:51
<cliebow_>
that script sets up bothe client side and server side..
10:51
<john_s>
hmm
10:51
what do you mean client side?
10:52
<cliebow_>
john_s, i guess i am confused
10:53
<john_s>
I guess I am more confused :-)
10:53
sorry to be confusing
10:53
I am sort of trying to do something that doesn't require me to add domains
10:53
<cliebow_>
you want a fileserver available from linux windows..macosx?
10:53
<john_s>
yes
10:53
thanks
10:53
:-)
10:54
And it should scale and handle auth for several LTSP installations
10:54
I now that the other way to approach it would be to install unix services for windows
10:54
but I hope to get rid of Windows *someday*
10:54
so i don't want to go in a direction that ties us to AD in some other form
10:55
Please tell me to get my head out of my ^%^&% if I am badly confused
10:55
P:-)
10:55
<cliebow_>
not at all..wish laprag were here..
10:56
<john_s>
who dat?
10:58
ok can I ask you another question?
10:58
it looks like you put the students in various ou's by year
10:58
then you put there homes in a flat /home
10:59
am I reading that right? And if so would it be very difficult to put them in something resembling
10:59
\home\gradyear
10:59* ogra shades his eyes
10:59
<john_s>
whoops that should read \home\grad_year\
11:00
ogra is that good or bad?
11:00
should i go away?
11:00
<ogra>
backslashes !
11:00
i havent seen them since some years, its always a shock :)
11:01
<john_s>
ah
11:01
right
11:01
<ogra>
nah dont go ... i'm just joking :)
11:01
<john_s>
that should read /home/grad-year/
11:01
whoops
11:01
yes
11:01
I live in both worlds
11:01
:-)
11:02
ok, well I'll just settle down here. Too much coffee, and I still have the rest of the summer to figure this out. Thanks again Cliebow, you rock!
11:06
<wpgmb>
can someone send me a link that will explain to me the file structure for an ltsp setup that shows where the different clients have their /home? Or am I thinking wrongly here?
11:08
<vykarian>
/say / =]
11:08
/home/grad-year/
11:09
<wpgmb>
vykarian: is that an anwer to my question?
11:10
<vagrantc>
wpgmb: typicalyl, the users log into the server and /home is the /home of the server.
11:10
wpgmb: there is no separate home per client
11:11
<wpgmb>
vagrant: ah...
11:11
how can an admin, by looking at /home, discern whose files belong to whom?
11:11
<ogra>
vagrantc, sbalneav, jammcq, doesn anyone see a reason to keep any of the old slow ldm in an ldm1 package or something ?
11:12
<sbalneav>
Hmmm
11:12
<ogra>
(i wont wipe it from the source yet, just talking about a binary package)
11:13
<sbalneav>
I think there's still a few things that ldm1 does that ldm2 might not do yet. I keep referring to it, so don't make it disappear quite yet :)
11:13
<ogra>
what would that be ?
11:14
apart from session and lang selection the new ldm does everything the old one did .... plus autologin
11:14
<sbalneav>
right
11:14
hey, I've got a problem with my tree here.
11:14
<ogra>
wsession and lang stuff shoud be fixable until release :P
11:14

oin$ bzr conflicts
11:14
Conflict: can't delete client/ldm2-0.1/autom4te.cache because it is not empty. Not deleting.
11:15
<ogra>
you ran autogen in your tree and didnt revert that before commit i guess
11:15
<sbalneav>
ah, nm, fixed it.
11:15
bzr resolv
11:15
<wpgmb>
May I re-ask: how can an admin, by looking at /home, discern which files belong to which client?
11:16
<ogra>
my tree doesnt have autom4te.cache
11:16
<sbalneav>
wpgmb: They don't
11:16
Dirs in /home belong to users, not clients
11:16
since any user can log in at any client.
11:17
<vagrantc>
never used the new ldm so i really can't make any comments
11:17
my tendency is to wait for it to prove itself :)
11:18
<ogra>
well, i want it in gutsy in any case
11:18
so getting testing earlier is better
11:19
<vagrantc>
sure. get it in. worst case is we revert back.
11:19
<ogra>
right
11:19
<vagrantc>
it's not like the code disappears.
11:19
kind of annoying to switch back, but...
11:19
<ogra>
heh, no, it rather grows all the time
11:20
sbalneav, i think it would make sense to port the ldm.c code to glib at some point, that will prevent many security headdaches
11:23
<wpgmb>
sbalneav: Ok. I understand that. Is it possible to separate / create (home)directories per user, independent of the client they're using?
11:23
*that would be "create" only*
11:24
<sbalneav>
ogra: I've never used glib, but I'd be more'n happy to learn.
11:24
<vagrantc>
wpgmb: that is the way it is.
11:24
<sbalneav>
wpgmb: Well, home dirs ARE independent of the client.
11:24
<ogra>
it makes froking and file operations easier ...
11:24
<vagrantc>
wpgmb: there are only user directories. no client directories.
11:24
<ogra>
and we dont have to care :)
11:25
<sbalneav>
ogra: Got a good tutorial on glib somewhere?
11:25
<wpgmb>
vagrantc: ok - those user directories - they can be looked at individually?
11:26

sbalneav, does that help ? http://developer.gnome.org/doc/API/2.0/glib/index.html

<vagrantc>
wpgmb: what do you mean?
11:27
<wpgmb>
vagrantc: sorry for my ignorance.. What I'm getting at is this - some of you use LTSP with many, many clients, and many different users. If an admin is asked to "filter" a certain individuals' files - how would he/she do that?
11:28
<ogra>
sbalneav, http://www.gtk.org/tutorial/c2025.html
11:28
<vagrantc>
wpgmb: well, all a user's fileswill be in their home directory.
11:28
wpgmb: i don't really know what you mean by filter
11:30
<wpgmb>
vagrantc: "look at" "backup" "delete" "whatever" .. I was under the impression from earlier answers, that all files created by users are stored in one massive directory. Now I'm back to the impression that every user has their own "/home" directory, from what you just told me
11:30
<vagrantc>
wpgmb: yes, every user has their own home directory.
11:31
<Gad1>
wpgmb: in Linux, user's home dirs are usually: /home/<username>
11:31
to backup all, backup /home
11:31
to backup one, backup /home/<username>
11:32
<wpgmb>
Gad1: Yep - that I know. But with LTSP being used, I seemed to have gotten some mixed answers, messages from other forums. That's why I'm asking
11:32
<Gad1>
or you can adjust home dirs to some other convention, but this is default
11:32
LTSP doesnt touch the way Linux servers work
11:32
just boots diskless clients to them
11:32
everything else works the same
11:33
<wpgmb>
ok - I'll set it up at home, and have a look. I'm one of "those people" who likes to have insight in things before they are obvious :o)

wpgmb, just imagine a thin client as an additional monitor/keyboard/mouse to the server
11:34
<wpgmb>
ogra: cool, with their own /home WITHIN /home, right?
11:34
<ogra>
does your keyboard ahve a /home in your PC ?
11:34
<wpgmb>
is that a trick question?
11:35
:o)
11:35
<ogra>
no
11:35
:)#
11:35
<wpgmb>
all my standalone's have their own /home, yes
11:35
obviously
11:35
<ogra>
its really noting more than additional IO devices on teh server that run over etherenet ...
11:36
<wpgmb>
ok. so please - humour me - when I log on to the server, and cd to my home, will the path be /user/home/wpgmb, or ...?
11:37
<ogra>
whatever it is on your server
11:37
<wpgmb>
ogra: I must be driving you guys nuts :-)
11:37
<ogra>
its the same path you have as if you would log in locally on the server
11:38muh2000_ has quit IRC
11:39
<ogra>
there is no difference between thin client and local logins ... the clienbt hardware itself is only an I/O device for the server so more than one monitor/mouse/keyboard can be used ... try to forget that they are computers :)
11:40
<wpgmb>
ogra: thanks. So - if I want, assuming I'm root on the server, I can cd to each individual's /home, and do whatever I need to do, JUST like as if there were many user accounts setup on one machine, which in essence, happened in the first place.. AAARGH!!!! I feel like the stupid kid who can't listen to the answer when he rambles off question after question
11:40
I'll go now, and go run into a wall or something
11:41
I do have another question, and sbalneav answered it, I think..
11:41
<ogra>
its not "JUST like as if there were many user accounts setup on one machine"
11:41
<wpgmb>
*gives up*
11:41
<ogra>
there ARE many user accounts setup on one machine
11:41
thats exactly it :)
11:41
<wpgmb>
phew - that is what I meant
11:42
<ogra>
in LTSP all is localized on one machine
11:42
you only need to maintain that one
11:42
<wpgmb>
how do you handle users walking away from their terminal, without logging off.. when you WANT them logged off after a certain time of inactivity?
11:42muh2000_ has joined #ltsp
11:43

there are tools for that
11:43
<wpgmb>
do tell...
11:43
<ogra>
teachertool in ltsp 4.2 and thin-client-manager in ltsp5
11:43
they offer you to lock the screens, log out users, send messages etc
11:44
or start apps on their desktops
11:45
<sbalneav>
wpgmb: You probably don't want them logged off, but rather locked.
11:45
You can set up the screensaver to lock after a certain amount of idle time.
11:45
<wpgmb>
but can this be done unattended - like, I'm not always at my desk watching my kids, telling them what to do
11:46
<sbalneav>
The screen will lock automatically, yes.
11:46
<ogra>
you could pick a very short time for autolocking
11:46
<wpgmb>
sbalneav: I'd sooner they'd be logged off, and let another user have access to that terminal
11:46
<sbalneav>
What happens if they leave a word processing document up on the screen, and didn't save their changes?
11:47
Then they lose it.
11:47
<Gad1>
tough nuggies!
11:47
:)
11:47
(or setup openoffice to autosave :P )
11:47
<sbalneav>
Umm, or just lock the screen. :)
11:47
<Gad1>
yeah, but that ties up the terminal
11:48
suppose another class comes in
11:48
or you're in an internet cafe
11:48
you could prolly wrapper the screensaver lock to wait n seconds after screen lock and then log out the user
11:49
<ogra>
nowadays ldm couold have a time that logs you out ;)
11:49
*timer
11:49

or both
11:50
or makes an incessant beeping noise!
11:50

log you out from your locked screen ?
11:50
<Gad1>
yeah, after being locked for too long
11:50
it aint YOUR workstation
11:50
<ogra>
or lock your screen while logging you out ?
11:50
<sbalneav>
Everyone in my house just stays logged in all the time, so I don't care one way or the other :)
11:50
<Gad1>
sbalneav: you should start charging them ;)
11:51
then, you'd care
11:51
:)
11:51
<sbalneav>
Oh, yeah, start charging my wife and kids.
11:51
<ogra>
Gad1, yes., talk him into that, we're missing a charge plugin for TCM still
11:51
<wpgmb>
so... I should stop being a tight-ass 'bout it, is that what i'm getting? :o)
11:51
<sbalneav>
People who HAVE to charge, can care.

11:53

11:54
I've merged the changes, btw.
11:54

the nicest way to make a system call :)
11:54* sbalneav actually feels like he knows what he's doing now with bzr
11:54
<sbalneav>
Man. I've come so far in 5 years.
11:54
<ogra>
thats what i mean by "switch to glib" ... we dont need to switch the whole app, but the critical functions
11:54
<cliebow_>
sbalneav:how would this affect memory requirements..
11:54
in client?
11:55
<ogra>
that'll make it a lot easier to get it past the security team :)
11:55
<cliebow_>
think a 32 meg client could stand it?
11:55
<sbalneav>
I'd expect glib shouldn't add too much
11:55
32 megs works now with python.
11:55
<ogra>
cliebow, well, i ran 28M clients with the old greeter here last week
11:56
<sbalneav>
current LDM2 size is about 20K stripped :)
11:56
<cliebow_>
Coolio...TIME TO MIGRATE 8~)
11:56
<sbalneav>
so I'd say we've got a bit of breathing room.
11:56
<ogra>
with the new automatic NBD swap from initramfs it shouldnt matter anyway
11:56
<cliebow_>
well....still cant load a 2.6 kernal on the little duffers
11:57
<ogra>
cliebow, these boxes have 32M ?
11:57
<cliebow_>
the netvistas i could get 64 pretty easy..just cant get a 2.6 kernel y load
11:57
to load
11:58

ah, so its no memory problem there
11:58
<Gad1>
cliebow_: did you try with apm=off acpi=off
11:58
?
11:58
those old IBM CPUs can have many issues with power management
11:58
<cliebow_>
i have no options whatsoever in the bios..

no, pass those on kernel commandline
11:59
(in pxelinux.cfg/default
11:59

hmmm..
12:00
they require an uncompressed kernel...

"in elf format"??

anybody has any idea about integration of LTSP 5 in Fedora
14:02
<jammcq>
meaning, it'll get done when it becomes important enough for someone to do it
14:02
<sbalneav>
ibt: If you'd like to help code it, it'll get done faster :)
14:03
<jammcq>
shishir_: we've talked to the Fedora guys quite a bit about it, but so far, they don't have the resources to put on getting it done
14:04
<shishir_>
I am really having tough time configuring sound for the thin clients and after trying out the edubuntu i really feel that LTSP 5 is a breeze as compared to earlier versions as far as sound is concerned
14:05
<jammcq>
shishir_: yeah, you've got ogra to thank for that one. The fedora guys understand that it's important to get LTSP-5 integrated. it's just a matter of finding enough hours in the day
14:06

ibt: Currently, the bazaar branch at: https://code.launchpad.net/~sbalneav/ltsp/scotts-gutsy is what I'm working on.
14:06

How well do you think LTSP 5 will run on clients with 64 Mb of RAM and 4 Mb PCI Graphics card with a PIII 667 Mhz processor
14:07
<jammcq>
shishir_: you may need to turn network swap on, but other than that, it should be fine

john_s: I'm on a switched LAN, and actually, the packets are travelling over a WAN. Still, performance is WAY below what it should be. I've gained slight performance boost from switching NFS to run over TCP rather than UDP but it's still beyond slow.
14:09
<ibt>
sbalneav: okay, checking it out
14:09
<jammcq>
gloin: check the blocksize being used by NFS. for slow link, I'd set it to 2k or 4k
14:10
the default is 32k, which is WAY too much for a slow link
14:10
<shishir_>
We have been running around 10 clients from a single server with a 100 mbps switch, do you think we will need to switch to Gigabit network for anything more than 10 clients
14:11
<jammcq>
can't answer that without knowing what kind of apps you are running

jammcq: I can set that in the pxelinux.cfg/default file as I did with changing to TCP, right?

So, ogra, if I wanted to add a message area to the greeter (i.e. "you typed an incorrect password", "please enter a new password", "system admin hates your guts"), I'd need to increase one of the vboxes by one, eh?
14:33* sbalneav frantically searches through his gtk book
14:34
<ogra>
yeah or just generate a new dialog
14:34
<ibt>
i'll bet it'd be even faster if you dumped the fancy images
14:34
<jammcq>
pop-up error messages are a pain
14:34
<ogra>
since the fullscreen thingie is just a gtk window (ulike gdm)we can do nifty things like switching it to insensitive (greying out the main win) while showing dialogs
14:37
<sbalneav>
ibt: the greeter's going to change fairly drastically, as we need to be able to actually interact with it over stdin and out.
14:37
<ibt>
sbalneav: why over stdin and out?
14:38
<sbalneav>
Well, we want ldm to be able to ask the greeter to display a login box
14:38
get the result,
14:38
display a password box
14:38bobby_C has joined #ltsp
14:38
<sbalneav>
oops, display an error message, etc.
14:38
ask for new passwords, etc etc etc
14:39
since the greeter is separate from the display manager, they need to communicate somehow.
14:39
stdin & out seems the most logical way to go.
14:40
<ogra>
sbalneav, for gutsy i'd be fine with popups, really ... i see the current greeter as throwaway code anyway its only purpose is to prevent regressions in usability while we have plenty of time to write something completely new for gtusy+1

14:43
<sbalneav>
