<perb>
hi, have some serious trouble with my k12ltsp installation
05:21
my clients will freeze after a short while
05:21
i get to log in, and the desktop is showing, but then it freezes after approx. 5 secs
05:22
any ideas what to do?
05:28
<sepski>
perb, any problems on the server itself ? how it' it's load ? my first guess is shoddy network.
05:41
<perb>
no problems at the server itself
05:42
but got an gdm_slave_xioerror in the message log
05:46
also get an error on the server in the message log saying: server pcscd: winscard.c:219:SCardConnect() Reader E-Gate 0 0 Not Found

morning al
10:01
all
10:02
I've got a client machine with builtin S3 video with 2MB video ram
10:03
X won't start, keeps giving me an 'out of scan range' error
10:04
is this just a monitor problem?

hi all
10:15
hi petre
10:16
hi dm
10:17
<petre>
hi AbuSami
10:18
<AbuSami>
can we discuss something
10:20
petre ?!
10:25
<petre>
sorry, stepped away for a moment
10:25
what's up?
10:27
<AbuSami>
I did you every heared about mille-xterm
10:27
peter ,
10:27
http://www.linuxjournal.com/article/9097
10:28
<petre>
yeah, I think it's some folks up in Quebec doing 'remote display with thin clients' kinda stuff
10:28
similar to ltsp, but separate
10:28
<AbuSami>
yeah,
10:29
can you help me about
10:29
they are talking about 1000 clients
10:29
<petre>
right, not quite sure how they're doing it, though
10:30
unless they're using really big hardware
10:30
<AbuSami>
I don't have enough resources
10:30
<petre>
messages from them occassionally appear on the ltsp mailing list
10:30
what are you trying to do?
10:30
<AbuSami>
do you think !
10:31
I want to scale out numbers of supported clients
10:31
is this possible ?
10:31
<petre>
how many clients per server do you have now?
10:32
<AbuSami>
I'm using DELL , 1G , P4, it holds 7 clients
10:32
<petre>
sounds about right
10:32
you could probably get to 10 clients depending on the apps the users are running
10:33mistik1 has quit IRC
10:33
<petre>
if you use a lighter weight desktop than gnome or kde, you might get a few more clients
10:33
<AbuSami>
hmm, normal applications, OpenOffice, QCad..
10:33
not that heavy one
10:33
<petre>
rule of thumb is 100mb ram per client
10:34
usually don't need that much, but if you go by that, you won't overload the server
10:34
<AbuSami>
do you have any idea to do this !
10:34
<petre>
1000s of clients?
10:34
<AbuSami>
yeah, they are talking about this number, read the site http://www.linuxjournal.com/article/9097
10:34
<petre>
QCad might be graphically intensive
10:35
yeah, I remember reading the LJ article (been a subscriber many years)
10:35
<AbuSami>
hmm
10:36
about QCad , rarley used, OpenOffice widely
10:36
<petre>
If you look at the diagram in the article, you'll see they're using clusters of servers
10:36
<AbuSami>
yeah,
10:36
<petre>
some for display, some for apps, etc.
10:36
<AbuSami>
it seems nice
10:37
<petre>
I don't think it's 1000s of clients on a single box
10:37
You can scale up to this by dedicating apps to specific servers
10:37
<AbuSami>
no, they said that based on cluster
10:37
<petre>
Largo, Florida does this.
10:37
One app per server
10:37
<AbuSami>
what he did
10:37
how this could be ?
10:38
<petre>
The got their per desktop memory down to 13MB
10:38
<AbuSami>
waw.. great
10:38
<petre>
on terminal server, but remember it was running no apps like OOo or anything, just dekstop
10:39
<AbuSami>
hmm.
10:39
<petre>
If OOo, say, is your biggest use and memory consumer, install that on a separate machine
10:39
have it NFS mount the /home from the LTSP server
10:40
then give user an icon that calls 'ssh appserver ooo' and ooo will run on the app server rather than the ltsp server
10:40
you could do this with each app
10:40
<AbuSami>
very goof idea
10:40
good *
10:40
<petre>
if you have multiple servers, ldap really helps centralize authentication
10:41
but you can start small with just one app server
10:41
<AbuSami>
you mean, server for LTSP ( DHCP,TFTP.. ) and the another one for application server for each application
10:41GodFather_ has joined #ltsp
10:42
<petre>
keep the IDs & PWs in sync by using rsync to copy passwd, groups, and shadow over to app server
10:42
<AbuSami>
very nice and effective idea
10:42
<petre>
yes
10:42
simple, too
10:42
<AbuSami>
yes
10:42
I will try it
10:43
<petre>
although K12ltsp's smbldap installer script is pretty easy from what I've read; haven't tried it.
10:43
bbiam
10:43
<AbuSami>
I was thinking so far about cluster it self ( OpenMosix )
10:44
I use LTSP 4.2, I never tried K12
10:44
to get one side cluster pool and intermediate LTSP server and another side Clients pool
10:45
peter ?
10:45

ltsp 4.1 on ubuntu does not work for me because: rc.localdev fails with *''SERVER = 192.xx.xxx.x command not found* its a double quotation mark at the beginning. seems to me like the eval `getlstcfg -a`in rc.localdev does not correctly parse the line SERVER = 192.xx.xxx.x. hints?
15:19
<jammcq>
did you edit the /etc/ltsp.conf file? or the /opt/ltsp/i386/etc/lts.conf file ?
15:20
<gmanic>
just to match the correct adresses. but it fails no matter what i have first after [default]. it always gets the two single quotation marks when i run getlstcfg.
15:21
<jammcq>
why do you have ANY quotation marks ?
15:21
you shouldn't need them
15:21
<gmanic>
i dont know. i do not have any in the lts.cfg. they show up with getltscfg and eval of course bails out.
15:22
the lts.conf shows in that particular line only
15:22
SERVER = 192.168.178.99
15:22
nothing else.
15:22petre has joined #ltsp
15:24
<cliebow>
gmanic:erase it with vim and retype..it would work for me but i never make any spelling errors..so i dont have to
15:25
<jammcq>
gmanic: show me a couple of lines leading upto that SERVER line
15:25
<gmanic>
as for me. i'll take nano, though.
15:25
[Default]
15:25
SERVER = 192.168.178.99
15:27
and this is the output (ok, not the client, but the same happens there):
15:27
root@server:/opt/ltsp/i386/etc# ../bin/getltscfg -a -c lts.conf
15:27
''SERVER="192.168.178.99"
15:27
the two quotations at the beginning are two single quot. marks.
15:28
<jammcq>
hmm, i'm thinking youv'e got some control chars embedded in the file. there's no reason that getltscfg would insert any extra chars in there
15:31
<cliebow>
jammcq: did you look at thoe packet captures?anything jump out at you?'
15:31
<gmanic>
ok, i'll delete including the [default] and retype. be back in a min.
15:32
<jammcq>
cliebow: sorry, I haven't looked at it
15:32
<gmanic>
now, the file starts with [default] and the next line is that SERVER def. output reads the same. two single quot. marks causing eval to bail out.
15:33
<jammcq>
gmanic: do this:
15:33
od -x -a lts.conf
15:34
and paste the results
15:36
<gmanic>
pastebot does not work for me, shall i paste here?
15:36
<jammcq>
yeah, should be short

sorry, my irc got mixed up somehow. anything on the paste output?
15:51
<cliebow>
jhammcq says looks fine
15:52
<gmanic>
hm. what else could cause the two single quotations marks, then?
16:07
<jammcq>
what happens if you run the thin client?
16:07
running getltscfg from the server isn't how it was intended to be run
16:09
<vagrantc>
jammcq: speaking of getltscfg ... wouldn't it be faster to output 'export FOO="bar"' instead of 'FOO="bar"\nexport FOO' ?
16:09
<jammcq>
vagrantc: 'export FOO=bar' isn't supported on all shells
16:10
although it's probably supported on the shells that we care about
16:10
<vagrantc>
jammcq: it's supported by all POSIX shells ...
16:10
<jammcq>
but.... 'export' is built into the shell, so does it really matter?
16:10
<vagrantc>
actually, i='m not certain it's supported by all posix shells ...
16:10
<jammcq>
I have a hunch you would never notice a speed difference between the two ways of doing it
16:11
<vagrantc>
yeah, probably not.
16:11
<jammcq>
I know for certain it's not supported on SCO, although who really cares about that anymore?
16:12
<vagrantc>
it's supported by bash, dash and posh ...
16:14
jammcq: and don't you forget what the L in LTSP stands for :P
16:14
<jammcq>
heh
16:14
good point
16:15
I wrote getltscfg about 8 years ago, when I was still doing an awful lot of work on SCO Openserver
16:36
<cliebow>
posh.there is a new onr
16:37
<vagrantc>
cliebow: it basically aims to be a plain ol POSIX compliant "sh".

19:12DigitalNinja has joined #ltsp

19:15
<DigitalNinja>
LTSP 5 doesn't have a lot of documentation. Can you install this from scratch?
19:15
I'm on Ubuntu Dapper
19:20
<cliebow>
at the risk of being slapped up side of the head....sudo apt-get ltsp-server-standalone
19:20
then ltsp-build-client
19:21
<DigitalNinja>
I was looking at that
19:21
However, I didn't see any audio support
19:22
local device support required fixing and or patching a few things
19:22
<cliebow>
coming in feisty i understand.working the bugs out of pulseaudio
19:23
<DigitalNinja>
can I download and install 4.2 and get local device and audio support?
19:24
<petre>
cliebow: do you know if sound will work better w/feisty, or is it just the groundwork being laid?
19:24
that it, the apps have to be built for pulseaudio, don't they?
19:25
s/it/is/
19:25
<DigitalNinja>
petre: What distro are you using?
19:25
<petre>
fc5 & 6, k12ltsp
19:26
<DigitalNinja>
Do you get audio and local device support?
19:26
<petre>
ltsp 4.2
19:26
lda=yes
19:26
sound=mostly
19:26
75%
19:26
or so
19:26
<DigitalNinja>
What's with "sound=mostly"?
19:26
That doesn't "sound" good
19:26
<petre>
sound in mplayer with Quicktime doesn't work, for me anyway
19:26
<cliebow>
my sound works..i think..i dont have but one clienr with a sound card..
19:27
<petre>
Flash sound works
19:27
<DigitalNinja>
I need flash sound
19:27
<petre>
that works now
19:27
<DigitalNinja>
good
19:27
It looks like I need to get ltsp 4.2 and install that from the LTSP package
19:28
<petre>
apt-get is your friend
19:28
<DigitalNinja>
petre: It is but will I get audio and local device support
19:28
<petre>
if you install 4.2, you should
19:29
that's not to say you're guaranteed to not have trouble
19:29
<DigitalNinja>
I've used the Ubuntu Dapper packag but I don't think it supports local devices or audio. I've never tired it though
19:29
<petre>
try it;
19:29
<DigitalNinja>
do you know if there are any instructions for this
19:29
<petre>
for lda support, there's a checklist on the wiki for troubleshooting it
19:30
<DigitalNinja>
I'll take a look
19:30
<cliebow>
i have some edgy installs..but nnever really tried
19:31
<DigitalNinja>
I'm wondering if the ssh stuff will get in the way. You do know that the client connects to the server over ssh?
19:31
<petre>
DigitalNinja, there's a Documentation section on ltsp.org, that covers installing 4.2
19:31
plus the wiki
19:31
<DigitalNinja>
I'll check it out
19:31
It would be nice to use the Dapper package and then tweek it for audio and local device support
19:32
I'm not sure if the Dapper package is 4.1 or 4.2 though
19:32
<petre>
it's do-able; just try it and worry about the problems when the come up, 'cause they might not
19:32
cliebow, you any good with scan rates?
19:33
<DigitalNinja>
Then you need to know what release or revision
19:33
<petre>
DigitalNinja: I don't know
19:33
<DigitalNinja>
I guess I need to get off my butt and just jump in
19:34
<petre>
That's one nice thing about K12ltsp: the ltsp bits are already included
19:34
including lda
19:34
and sound mostly
19:34
<cliebow>
petre:not so hot..for an oddball monitor you mean?
19:34
<DigitalNinja>
I'll take a look at edubuntu. That has LTSP in it
19:34
<petre>
no, video
19:35
got a P166 with a S3 video
19:35
X fails for everything except 640x480
19:35
<cliebow>
wasnt there something on wiki about s3 and the old 3drivers?
19:35
<petre>
I've used the monitor for 1024x768 before
19:36
hmm...
19:36* petre goes to wiki
19:36
<cliebow>
http://wiki.ltsp.org/twiki/bin/view/Ltsp/VideoCards#S3_and_S3Virge_cards
19:38
<petre>
ah, that looks good
19:38
the machine only has 2mb video ram; does setting it to 4096 still work, do you know?
19:41
guess I'll just try it...
19:43
<cliebow>
best i can say is perhaps 8~)
19:45
<petre>
I think that page is outdated: I get a 'file not found' error if I set the xserver to xf86_s3
19:45
I think X is detecting the video correctly
19:45
I just can't get any resolution above 640x480
19:45* petre scratches head
19:46
<petre>
with 2mb video, I'd think I'd get at least 8x6
19:47
ironically, the point with this client is to show how *easy* it is to use old hardware for clients ;-)
19:52
okay, using the vesa driver, I can get 800x600; go figure
20:04
<cliebow>
heh
20:06
<vagrantc>
ubuntu edgy certainly supports local devices and audio. pretty sure dapper supports audio.
20:06* vagrantc is a little slow on the response
20:08
<vagrantc>
and edubuntu should be a pretty easy way to get ltsp installed
20:10
look in /usr/share/doc/ltsp-server/ for various bits of documentation

should an ltsp server be 32 bit if its supporting 32bit clients ?
21:15
<vagrantc>
64 bit servers should be able to host 32 bit clients without troubles.
21:15
other way around is trickier
21:17* vagrantc says this having never touched a modern 64 bit machine

I've just installed K12LTSP 6.0 on a PIII server in my office, replacing one running K12LTSP 4.1. My thin clients run fine, but my two Macs that rely upon the server for internet routing are not connecting. I'm assuming something in my service configuration needs to be turned on, but don't know what. Any assistance gratefully appreciated.
21:21
Well, thanks anyway.
