anyone there to help with ltsp-5 in debian ??
10:53
i try to start a client with PXE. the client boot but no graphical display is coming up. i am using gdm
10:56
<rjune_>
netstat -anp, look for 166
10:56
I think.
10:56
it's been a while.

i have install ltsp-server 5.0.39debian1 and than ran ltsp-build-client
11:03
with --dist etch
11:04elisboa has joined #ltsp
11:07
<vagrantc>
mitmobiler: is ltsp-server installed on an etch or lenny system?
11:08
<mitmobiler>
vagrantc: ltsp-server is installed on lenny but the chroot environment is etch
11:09
<vagrantc>
mitmobiler: 5.0.39debian1 of ltsp-server will not correctly install an etch chroot without some manual configuration
11:09
mitmobiler: i'd recommend following the instructions on http://wiki.debian.org/LTSP/Howto for using the etch backports
11:12
<mitmobiler>
vagrantc: txs i will try now
11:13
<vagrantc>
mitmobiler: you should be able to just use the ltsp-server package from lenny, but you'll need to pass the --extra-mirror option and set up apt's gpg keyring with apt-key

I did this and now I got some mount errors while booting a PXE client
11:31
mount: Mounting /dev/nbd0 on /rofs failed: No such device
11:31
>> mount: Mounting unionfs on /root failed: No such device
11:32
>> mount: Mounting /rofs on /root/rofs failed: Invalid argument
11:32
etc ...
11:33
<vagrantc>
ah.
11:34
hmmm...
11:34
that shouldn't happen if you built an etch environment
11:34
mitmobiler: dpkg --root=/opt/ltsp/i386 -l initramfs-tools | egrep ^ii
11:35
<mitmobiler>
after installing ltsp-server in lenny i build chroot with
11:35
ltsp-build-client \ --extra-mirror "http://pkg-ltsp.alioth.debian.org/debian etch-ltsp-backports main" \ --apt-key /etc/apt/trusted.gpg
11:36
<vagrantc>
mitmobiler: so it probably built a lenny chroot
11:36
mitmobiler: dpkg --root=/opt/ltsp/i386 -l initramfs-tools | egrep ^ii
11:36
<mitmobiler>
ii initramfs-tools 0.91d tools for generating an initramfs
11:36
<vagrantc>
either lenny or sid
11:36
mitmobiler: why do you want an etch LTSP on a lenny server?
11:37
mitmobiler: dpkg --root=/opt/ltsp/i386 -l 'ltsp*' ldm | egrep ^ii
11:37
<mitmobiler>
i don't but I had the same issues as now with lenny in chroot
11:37
<vagrantc>
mitmobiler: it's fixed in sid
11:37
mitmobiler: --dist sid
11:38
<mitmobiler>
dpkg --root=/opt/ltsp/i386 -l 'ltsp*' ldm | egrep ^ii
11:38
ii ldm 5.0.39debian1 LTSP display manager
11:38
ii ltsp-client 5.0.39debian1 LTSP client environment
11:38
ii ltsp-client-core 5.0.39debian1 LTSP client environment
11:38
ii ltspfsd 0.5+debian1 Fuse based remote filesystem daemon for LTSP
11:39
I can give it a try with sid
11:39
<vagrantc>
should hit lenny within a couple days

<mitmobiler>
vagrantc: what do you mean ??
11:42
<vagrantc>
mitmobiler: there is a package in sid which fixes your problem, and it should make it into lenny tomorrow, the next day, or the day after that
11:43
<mitmobiler>
ok thanks

rjune_, 177: for xdmcp..most are using ldm so no need for it?
12:23
<ogra>
vagrantc, what squashfs version does sid have atm ? i have soem changes in ubuntu that i'd like to push upstream soon, but one requires an option only in the latest squashfs relese
12:24
<vagrantc>
ogra: squashfs-source | 1:3.3-1 | unstable | all
12:24
<ogra>
ah, cool
12:24
that needs the -lolzma option ... else it will default to lzma compression
12:24
<rjune_>
cliebow: I don't know how it works anymoe.
12:24
anymore.
12:25
<vagrantc>
ogra: is it better compression... faster... ?
12:25
<rjune_>
*sigh*, I'm so behind LTSP
12:25
<ogra>
(which is a cool thing (about 1/3 higher compression rate) ... beyond the fact that no kernel can unpack it yet :P )
12:25
we need to keep it until the kernel module can handle lzma
12:26
<cliebow>
rjune_, it progesses so fast none of us old fogies can keep up
12:26
<rjune_>
LOL
12:26
did you see the movie of my new toy?
12:26
<ogra>
and after testing all clients i got here i finally switched over to the -generic image
12:26
rjune_, another BMW ?
12:26
<rjune_>
heh no
12:26
this was brand new.
12:26K_O-Gnom has quit IRC

and you say that as if it works.
12:27
http://www.bravegnuworld.com/~rjune/mov005.mod <-- dicky got a new toy
12:27
it's wintertime, so I need to go see about fixing that old car
12:28* ogra has a dissembled prosche in the garage .... since over a year now ...
12:28
<ogra>
about the same age as your bmw
12:28
<rjune_>
heh
12:28
so I'm in good company then.
12:28
I hope to be driving it this summer
12:29* vagrantc needs to get the bicycle working *again*
12:29
<ogra>
heh, think about trashingit .. i simply dntfind the time
12:29
s/think/i think/
12:29
<vagrantc>
first thing i do for the year is break a bike pedal... and then a couple days later my tire dies
12:29
<rjune_>
unfortunate. I bet an old porche would be fun
12:29
jeebus
12:30
<ogra>
its only a 924 ... rather an audi than a porsche ...
12:30
<rjune_>
heh
12:30
<ogra>
but only takes 7l/100km .... i never had a car taking so less
12:31
(thats less than i.e. a vw golf)

cool
12:31
<putnum>
can ltsp serv windows apps to linux thin clients?
12:33
<cliebow>
putnum, that is tough
12:33
ive never gotten crossover or wine to work on any of the apps i needed
12:33
<ogra>
putnum, some .... through wine/codeweaver ... but you usually break the licensing through that heavily
12:34
<putnum>
yea
12:34
thought so
12:34lns has joined #ltsp
12:34
<putnum>
i am looking for a good open source alteritive to citrix
12:35
i have linux thin clients and i want them to be able to access windows apps from the backend
12:35
<cliebow>
ltsp rocks..unless you have like teachers glued to special ed windows apps
12:35
you "can" use rdesktop
12:36
if you have aserver that will rub rdp
12:36
<putnum>
yea i saw that
12:36
<cliebow>
/rub/run
12:36
<putnum>
is it pretty stable?
12:36
<cliebow>
very
12:36
<rjune_>
fairly
12:36
<putnum>
this is for my house
12:36
not a business
12:37
<cliebow>
i suppose you could even vnc into a win boxen for win apps
12:37
<putnum>
and i can run it seamless? and what about when i have two users accessing two windows apps at once how does that work?
12:38
<cliebow>
errrrr..prob not so hot..you must have a big family
12:38
<putnum>
well not really
12:39
i am wanting the thinclients to boot up and only have access to certain windows apps and the internet via the windows server
12:39
kinda like citrix meteframe
12:39
<cliebow>
leave the internet on linux..
12:40
<putnum>
k
12:40
<rjune_>
do you expect multimedia heavy usage?
12:40
<cliebow>
any one win app you "really" want?
12:40
rjune_ has a point..
12:40
<putnum>
well i am a photographer so i use photoshop heavily and my wife wants only ie7
12:41meduxa has joined #ltsp
12:41
<putnum>
and i use outlook 2007
12:41
<cliebow>
gimp rocks as a clone to photoshop
12:41
<rjune_>
ie7, that doesn't bode well. for YouTube? or such? that would be multimedia
12:42
<cliebow>
you could get used to evolution..in time
12:42
<rjune_>
and historically terminals don't work so well for that
12:42
<vagrantc>
(always hears people who are really intensive users of photoshop claim gimp isn't worth it)
12:42
<putnum>
lol
12:42
<cliebow>
vagrantc: i see..
12:42
<putnum>
well i know ps already
12:42
<ogra>
vagrantc, i would oppose that as someone who worked in graphics business for three years :)
12:42
<vagrantc>
i mean, for most people, gimp is probably fine
12:43
ogra: you're one of the few, then
12:43
<ogra>
gimp was always far beyond PS if you come to web graphics development
12:43
<putnum>
so i could use rdesktop and i would only be able to run one app at a time which would be fine
12:43
<vagrantc>
the real answer to that question is: try gimp and see if it works for you
12:44
<ogra>
at least back around 2000 when i worked with it and made my co workers jealous with my gifs that were cretaed like a breeze while they had to push it through ten apps to get similar results ;)
12:44
i think Ps won a lot here in the years i didnt see it
12:45
<putnum>
can i have my linux clients boot up into a rdesktop session?
12:46
<vagrantc>
putnum: yup
12:46
<putnum>
with out having access to the apps on them locally?
12:46
how?
12:46
<ogra>
needs some manual work, but yes
12:47
vagrantc, btw, shoudlnt we add rdesktop to ltsp-client deps ?
12:47
(without enabling it indeed)
12:47
<cliebow>
sounds like a good idea..
12:48
<vagrantc>
ogra: well... depends on if we require the functionality to be present on a "standard" ltsp setup, or think of it as an optional feature.
12:48
<ogra>
optional but to enable without having to install anything
12:49
i'd like to have the binary there at least
12:49
<vagrantc>
it's reasonably small, looks like
12:49
<ogra>
with nbd you need to chroot ... install, rebuild the image ...
12:49
versus just enabling an lts.conf option
12:49
<vagrantc>
sure
12:50
sounds reasonable to me...
12:50
<ogra>
i'll add it after the freeze to the ubuntu deps
12:50
(friday)
12:51
<vagrantc>
oh.
12:51
<ogra>
alpha3 freeze started today and with it ltsp and the installer pieces moved on the ubntu alternate CD :)
12:51
<vagrantc>
there's 1 RC bug on debian for rdesktop that's been there for 92 days...
12:51
<ogra>
*ubuntu
12:51
<vagrantc>
definitely won't make it a hard dependency until that goes away :)
12:52
<ogra>
whats that ?
12:52
<vagrantc>
#445780: rdesktop segfaults connecting to Windows 2000/2003 server
12:53
<ogra>
wow, thats RC ?
12:53
there is an easy workaround ... set your colors to 16bit
12:54
oh, i should read to the end :)
12:56
<vagrantc>
no comments from the maitainer in 90+ days on a release-critical bug. not a good sign.
12:56cyberorg has quit IRC
12:57
<vagrantc>
at least it allegedly works fine on the version in testing
12:57
<ogra>
sounds a bit similar to https://bugs.launchpad.net/ubuntu/+source/rdesktop/+bug/104332
12:59putnum has left #ltsp

<MasterOne>
any clue, when resuming an existing session & session takeover will be implemented?
13:51
these features are kind of a showstopper for me right now :(
13:52
<johnny>
who knows..
13:53
they are too busy cleaning up the ltsp code and splitting it up to actually work on a lot of new features it seems
13:53
<MasterOne>
that's bad
13:54
actually a solution based on FreeNX would better fit my requirements
13:54
<johnny>
no.. it's good
13:54
for ltsp
13:54
great in fact
13:54
will be a lot easier to hack upon in the future
13:55
<MasterOne>
yes, I understand, I'd just wish LTSP5 would be already further right now
13:55
<johnny>
not enough folks working on it
13:55
all people want more stuff, but don't want to put any effort to making it happen
13:56
<MasterOne>
some merge of the LTSP5 concept + FreeNX would be the desired solution
13:56
<johnny>
i bet doing that wouldn't be too hard
13:56
<MasterOne>
FreeNX can do both, session resume & takeover
13:56
<johnny>
replacing X with freenx can't be that difficult
13:57elisboa has quit IRC
13:57
<johnny>
maybe X itself can do it.. i just don't know how it's done\
13:57Q-FUNK has joined #ltsp
13:57
<MasterOne>
another approach could be x11vnc, which also allows VNCing into an already running session

13:59cyberorg has joined #ltsp
13:59Guaraldo has quit IRC
14:02
<Gadi>
MasterOne: so, why not use NX?
14:02
you can quite easily make a network-booted thin client that runs nxclient
14:03
<MasterOne>
I already thought about that
14:03
<Q-FUNK>
howdy!
14:03
<Gadi>
even using LTSP5 as the base
14:03
Q-FUNK: howdy
14:04
<MasterOne>
will have to do some more digging, till now I only tested the nomachine NX server + client (which is free, but only allows 2 concurrent sessions)
14:05
Gadi, btw I got Compiz working on the thin client with 1920x1200 ;)
14:05
<Gadi>
were you the one with the sis chip?
14:06
or was it s3?
14:06
something non-ati/nvidia/intel
14:06
<MasterOne>
yes
14:07
<Gadi>
what was the trick?
14:07
<MasterOne>
but the Compiz test was done on a radeon
14:07
<Gadi>
ah
14:07
<MasterOne>
but it should work fine on s3 es well
14:07
<Gadi>
so you never fixed it for that chip
14:07
oh
14:07
I remember issues with direct rendering reporting no on the server but yes on the client
14:08
<MasterOne>
the trick was to disable DRI on the server, and to copy over the Xorg.6.log file from the TC to the server
14:10
it was mentioned somewhere, that DRI disables the GLX remote ability, and compiz checks the Xorg.log file on start if the environment is compatible (which is not the case on the server itself)
14:14
<Gadi>
ah
14:15
MasterOne: if you like, you could comment out the line near the bottom of /opt/ltsp/i386/usr/lib/ltsp/configure-x.sh that calls "append_dri"
14:15
then, you could use CONFIGURE_X=True in your lts.conf
14:16
and all the other X params will be set-able
14:16
<MasterOne>
no need for that, DRI on the TC stays enabled, it just needs to be disabled on the server
14:16* Gadi makes mental note that append_dri should be lts.conf configurable, as well
14:16
<Gadi>
?
14:16
<johnny>
hmm.. but i use my server as a desktop..
14:16
so that wouldn't work for me
14:17
<Gadi>
when does the xorg.conf on the server ever get used?
14:18
<MasterOne>
I didn't find an explanation for that, but that's what I did, and then it worked
14:18
<Gadi>
and you didnt disable dri on the client?
14:18
<MasterOne>
no
14:18
<Gadi>
bizarre
14:18
<MasterOne>
after disabling DRI on the server, the error message in glxinfo output changed
14:19
<Gadi>
smells like an upstream bug in glx
14:19
:)
14:19
<MasterOne>
then it was only the missing Xorg.log, which kept Compiz from starting

14:50
vagrantc: it'll always be frozen due the udeb
14:50
vagrantc: you always need to ask for it approval

14:51

14:56
vagrantc: so it would allow you to update the whole ltsp without this mess
14:57
<vagrantc>
otavio: that would be nice
14:57
otavio: that would be simple to do
14:57
otavio: haven't made updates to the udeb in a long, long time

hi all
15:08
i having problems wick pendrive users, the pendrivers dont mount in user terminals, lookink at terminal dmesg i look that " sda: unknown partition table"
15:08
<PerfDave>
ryudo: Do they mount on non-client machines?
15:09
<ryudo>
yes !
15:09
in my server mount
15:09
but im my old terminals ( celeron 333 + 64 ram + usb 1.0) no
15:09
the pendrivers are usb 2.0
15:09
but my pendrive
15:09
one kingstone 2 gb
15:09
mount normaly in my terminals
15:10gonzaloaf has joined #ltsp

<ryudo>
Some pendrivers mount others not
15:11
kingstone 2 GB mount, but PQI 2 GB pendrive not :(
15:12
<PerfDave>
ryudo: The PQI mounts on the server, but not the client. The Kingstone mounts on both. Is that correct?
15:12
<ryudo>
yes that is !
15:12
sorry perdave
15:12
my english is not good :(
15:12
<PerfDave>
That is OK :)
15:13
<ryudo>
both pendrivers are formating in FAT
15:14
perfdave do you know how i fix it ?
15:14
<PerfDave>
What GNU/Linux distributions are you using for your server and clients?
15:15

ryudo: it is not how they are *formatted* but how they are *partitioned* that matters
15:15
<ryudo>
wich last updates
15:15
<Gadi>
can you plug each into the server, and run: fidsk -l /dev/sda
15:15
(or whatever /dev/ they are)
15:15
on each

it looks for a recognizable filesystem on the drive partition
15:22

i need fix it on terminals ?
15:22
<Gadi>
if there is no partition that it recognizes, it won't recognize the drive
15:22
well, the best thing to do is get one of those drives, and come back for help

hard to fix the problem when you don't have it at the moment

yes gadi

can you get one of those drives?

ryud: that pen drive is amongst some that report a false partition table
16:58
these, by default, aren't handled on the terminals, because the mechanism on the terminals tries these false partitions looking for a filesystem that is not there
16:58* Gadi had written some code at some point to work around this, but didn't have a drive like that to test it :)

hi everybody, i wanna ask if the thin-client does have an X server ..
23:19
<sutula>
aboo0ood: It does...that's about all it has (usually)
23:20
<aboo0ood>
sutula, and there's an X server on the LTSP server ?
23:20
sutula, shouldn't the client have an X client instead of X server ?
23:20
<sutula>
aboo0ood: Not used for ltsp...doesn't have to have one at all
23:21
aboo0ood: The X programs are clients running on the server, and talk to the thin-client's X server
23:22* sutula thinks that surely, someone else here can explain it better, as sutula is tired
23:22
<aboo0ood>
sutula, thanx
23:23
anyone can help ?
23:24
<sutula>
aboo0ood: Have you ever logged into a remote machine, then used something like "ssh -X" to send the window from an X application back to your computer? It's basically like that.
23:24
<rjune_>
the X server talks to the graphics hardware. X clients are the programs that talk to the X server
23:24
it's backwards what you would initially think, but it it makes sense
23:26
<aboo0ood>
rjune_, X server is just an interface between progs and the HW ?
23:27
<sutula>
aboo0ood: Yes...an interface that can handle connections from multiple programs and the hardware
23:29
<rjune_>
pretty much
23:31
<sutula>
aboo0ood: Are you just trying to wrap your mind around what ltsp is, or is there something more you're trying to understand?
23:32
<aboo0ood>
sutula, i was reading about X window system trying to understand LTSP
23:34
<sutula>
aboo0ood: Think of it as the thin client providing the screen, keyboard, and mouse that are being used by programs running on a central server
23:35
<aboo0ood>
sutula, i got this point, now i am trying to figure out what's the role of the display manager and how it works !
23:36
sutula, i was reading in wikipedia : "A display manager can run on the same computer where the user sits or on a remote one. In the first case, the display manager starts one or more X servers"
23:36
can more than one X server be started !
23:36
<sutula>
aboo0ood: It makes the initial connection between the thin client and the server...sets up the whole environment so that a user can run programs
23:37
Each thin client has it's own X server, so yes
23:38
aboo0ood: I think terminology gets in the way here
23:38
When X speaks of a display manager, it's like gnome or kde (or a myriad of others)
23:39
ldm (which is the ltsp display manager) is really only for the initial login screen and setting up the connection between the thin client and what ends up running on the central server
23:40
<aboo0ood>
where does LDM reside ?
23:40
<sutula>
aboo0ood: It runs on the thin client as it boots up
23:41
...but that may be misleading because it uses pieces on the server to do what it needs to do as well
23:42tux_440volt has joined #ltsp
23:44
<aboo0ood>
sutula, so after the thin client boots up it runs LDM which initiates communication with LTSP server, which communicates with the X server on the thin client to display the login screen ??
23:44
<sutula>
Yes...I wish I could have answered you that clearly earlier :)
23:48
<aboo0ood>
sutula, wikipedia says : "A display manager can run on the same computer where the user sits or on a remote one. In the first case, the display manager starts one or more X servers, displaying the login screen at the beginning and (optionally) every time the user logs out. In the second case, the display manager works according to the XDMCP protocol."
23:48
and older versions of LTSP used to use XDMCP, so isn't it that LDM resides on the server ?
23:49
<cyberorg>
ldm is client side
23:49
<aboo0ood>
what was XDMCP used for then ?
23:50
<cyberorg>
xdmcp is run on the server, it allows remote X session
23:51
ldm is run on the client and it jsut does ssh -X user@server Xsession among other things
23:51
both almost have same effect but technically they are world apart
23:52
<sutula>
XDMCP provides similar functionality to ldm, but ldm was written later and is specifically for ltsp...it is more tuned for that use
23:53
<aboo0ood>
isn't the ssh -X part done from the server to the thin-client ?
23:53
<johnny>
no
23:57
<aboo0ood>
thanx guys
23:58* sutula nods
