LTSP Setup Question: I want to put LTSP terminals in my house. The home network has a star topology, with all nodes connected to a central router. That router serves DHCP. Do I need to switch off the router's DHCP feature and give the job to a daemon on my linux server box? Thanks.
00:54
<vagrantc_>
|Philip|: if you can configure your router to give out the filename, next-server and root-path options, you might be able to just use that for the DHCP servr.
00:55
|Philip|: some routers can't do that, some are really hard to figure out... so it might just be easier to use the LTSP server as your DHCP server and shut off DHCP on your router.
00:55mistik1 has joined #ltsp
00:55
<|Philip|>
Thanks for answering. I don't think my router is smart enough to do all that. Do you use any network gadget (router/switch/hub)? Can you briefly outline your setup?
00:56
<vagrantc_>
the other option would be to put two network cards in your LTSP server, and set up a separate physical network for the thin-clients ...
00:57
typically, i've got a DHCP server plugged into a switch/hub. sometimes that DHCP server is the same as the LTSP server, sometimes it's another linux box. doesn't make too much difference.
00:58
<|Philip|>
I'd rather play with software than install new hardware. I think I might have a spare network card somewhere, but then I would also need a hub for the LTSP subnet. So I'll first try to copy the setup you are using.
00:59* vagrantc_ just uses /usr/share/doc/ltsp-server/examples/dhcpd.conf with ip addresses adapted to the network
01:00
<|Philip|>
I'm not too worried about this: DHCP is actually overkill for my current setup, because all my machines are static and their IP addresses are static, too. My first move will be to switch all boxes over to static IP addresses and see if the network can function with no DHCP server at all. Then I will try to start dhcpd on a network machine and work up from there. Do you think this could work?
01:02
<vagrantc_>
well, if you mean no DHCP for all non-LTSP machines, sure. but trying to set up LTSP without DHCP is a lot of work.
01:04
<|Philip|>
Yes, I meant reconfiguring all the working non-LTSP machines I have already to avoid DHCP so that I could keep the rest of the family functioning happily while going through the pain of organizing DHCP so that LTSP can be added.
01:05
Now I should check out and try some of this. Thanks a lot, fellow Cascadian, for helping me decide my next move. Bye!
01:05
<vagrantc_>
that shouldn't be hard.
01:06
glad to be of help
01:06
|Philip|: whereabouts in cascadia are you ?
01:07
<|Philip|>
Vancouver, Canada. I told this to the KVIrc client I installed 5 mins ago for the express purpose of learning more about LTSP. It has worked beautifully, thanks to you. Now I'm really really going. Bye!

can anyone give me documantation for debian ltsp
07:51
this onw is not http://wiki.debian.org/LTSP/ enough
07:52
<sep>
masus, you read the /usr/share/doc/ltsp* files ?
07:52
<masus>
i'll see one mom
07:53
<ogra>
!debian
07:53
<ltspbot`>
ogra: "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
07:53
<ogra>
!ubuntu
07:53
<ltspbot`>
ogra: "ubuntu" is a Debian based GNU/Linux distrubution that includes a Ubuntu specific version of LTSP. It can be found at http://www.ubuntulinux.org. to install ltsp on ubuntu: https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
07:53
<ogra>
both pages will have info
07:53
since LTSP is largely developed in ubuntu the docs apply for both distros mostly
07:53
<masus>
but i have do what is there but i get an error like PXE not found
07:54
<ogra>
did you use the -standalone package or only ltsp-server ?
07:54
<masus>
only ltsp-server
07:54
<ogra>
that doesnt set up the dhcp server
07:54
you need to do that yourself then
07:54
<masus>
i have do
07:55
<ogra>
PXE not found usually means your client doesnt get the right inf from the dhcp server
07:55
<masus>
http://pastebin.ca/705834
07:55
pleaselook at there , it's my dhcpd.conf
07:56
<ogra>
on a separate server
07:56
i assume
07:56
looks fine so far
07:56
are you using etch ?
07:56
<masus>
yes
07:56
debian etch
07:57
<ogra>
etch's initramfs had a bug where it couldnt split root-path properly into ip and path
07:57
<masus>
so what i can do
07:57
<ogra>
add nbdroot="<ip>:<path>" to your PXE defaultfile
07:57
err
07:57
nfsroot
07:57
<masus>
filename "/opt/ltsp/i386/usr/lib/syslinux/pxelinux.0
07:57
<ogra>
(sorry my head is on next gen ltsp already, we dropped nfs there)
07:58
<masus>
to this file
07:58
<ogra>
"/opt/ltsp/i386/usr/lib/syslinux/pxelinux.cfg/default
07:58
just add it to the end of the one line in there
07:58
<masus>
ok i'll try
07:58
<ogra>
ERRR
07:58
STOP !
07:58
thats totally wrong
07:59
filename "/opt/ltsp/i386/usr/lib/syslinux/pxelinux.0"; isnt a path you can see via tftp
07:59
must be filename "/ltsp/i386/pxelinux.0";
08:00
fix that in your dhcpd.conf first
08:00
<masus>
ok
08:00
<ogra>
if it still doesnt work *then* make the nfsroot fix
08:00
<masus>
but i have try it first
08:00
s ihave changed
08:00
but i'll fix it
08:01
i dont have this /opt/ltsp/i386/usr/lib/syslinux/pxelinux.cfg/default
08:02
<ogra>
no
08:02
as i said ... totally wrong path
08:02
did you make the fix in dhcpd.conf an try to boot a client ?
08:02
<masus>
yes
08:02
no
08:02
i don'try now
08:02
but for 30 minutes i have try
08:02
<ogra>
(dont forget to restart the dhcp server after changes ;) )
08:03
<masus>
yesy i have restart
08:03

08:08
<masus>
can u give me more tips :S
08:08
or how to fix this, i want to test the ltsp
08:09
<Guaraldo>
masus: verify the "file" parameter in your DHCP configuration file...
08:09
masus: Check if the file exist...
08:10
<masus>
http://pastebin.ca/705847
08:10
here is my dhcpd.conf file
08:10
u mean this file to check ? filename "/ltsp/i386/pxelinux.0";
08:11
"/opt/ltsp/i386/usr/lib/syslinux/pxelinux.0"
08:11
<sbalneav>
that's wrong
08:11
<masus>
hmmm
08:11
and how to fix it :)
08:11
<sbalneav>
you should look in /var/lib/tftpboot/ltsp/i386
08:12
What tftpserver do you have installed?
08:12
on the server?
08:12
<masus>
tftpd-hpa - HPA's tftp server
08:13Uranellus has left #ltsp

and /var/lib/tftpboot/ltsp/ is empty

:S
08:14
<sbalneav>
Well, there's your problem
08:14
run ltsp-update-kernel
08:15
<masus>
http://pastebin.ca/705850
08:15
i have do it now can u look if it's right now ?
08:15
do i have to change now something on dhcpd.conf
08:16
<sbalneav>
No, but now your should have something in /var/libtftpboot
08:17
<masus>
yes i have
08:17
<sbalneav>
ok
08:17
<masus>
"/var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default"
08:17
<sbalneav>
thats good then.
08:18
<masus>

dpkg -|grep ltsp
08:28
lets see what you have all installed over there
08:28
<masus>
ok
08:29* ogra hopes ltsp-utils isnt in that list ... etch has a bad bug that lets you install ltsp 4 and 5 alongside which usually breaks
08:29
<masus>
dpkg -| grep ltsp / dpkg: need an action option
08:29
<sbalneav>
dpkg -l
08:29
<ogra>
thats a small L
08:30
<masus>
no it's not
08:30
<ogra>
not a pipe :)
08:30
err
08:30
whoops, my bad

ltsp-utilsis not installed
08:30
<ogra>
onyl ltsp-server ?
08:31
<masus>
oh sorry it is :|
08:31
<sbalneav>
That's a problem.
08:31
<ogra>
did you run any of the tools ?
08:31
i.e. ltspadmin
08:31
<masus>
ii ltsp-server 0.99debian11 Basic LTSP server environment
08:31
rc ltsp-utils 0.25 Provides server support program for use in a
08:31
i have do it yesterday but after i ahve learn that ltsp-utils is old version i have deinstalled
08:31
<ogra>
dpkg --purge ltsp-utils (so *everything* gets claned up)
08:32
ou still have the config files
08:32
<masus>
Removing ltsp-utils ...
08:32
<ogra>
(rc indicates that)
08:32
does /tftpboot exist ?
08:32
<masus>
no
08:33
have delete it yesterday
08:33
<ogra>
ok
08:33
oh
08:33
<masus>
:)
08:33
<ogra>
check that it doesnt show up in inetd.conf
08:33
then rm -rf /opt/ltsp/i386
08:33
ltsp-build-client
08:34
wait a while until its done ...
08:34
boot a client
08:34
<masus>
http://pastebin.ca/705872 inetd.conf
08:34
oh i have to wait 2 hours until it's finished
08:35
can i download the cd form anywhere
08:35
<ogra>
there is no tftp stanza at all in your inetd.conf
08:35tux_440volt has joined #ltsp
08:35
<ogra>
any debian CD should do
08:35
<masus>
ok , is my inetd.conf right ?
08:35
<ogra>
if you have one around, mount it and use ltsp-build-client --mirror file:///cdrom
08:36
no
08:36
it should contain tftp
08:36
<masus>
afterltsp-build-client it will be conatin tftp
08:36
?
08:36
<ogra>
nope
08:36
thats adjusted by ltsp-server iirc
08:36
<sbalneav>
ogra: So, we've got a couple of widescreens here (14-something by 1060 something). Before I had to specify custom xorg.conf's for them. Now they autodetect right out of the box. \o/ for configure-x.sh
08:37
<ogra>
yay
08:37
<masus>
so firs remove ltsp-server
08:37
<ogra>
no
08:37
<masus>
and build-client
08:37
hmm
08:37
<ogra>
remove ltsp-utils
08:37
then apt-get install --reinstall ltsp-server
08:38
(that will give you the tftp entry)
08:38
<masus>
dpkg - warning: ignoring request to remove ltsp-utils which isn't installed.
08:38
<ogra>
(unless debian hacked that up)
08:38
did you purge it before ?
08:38
<masus>
yes
08:38
<ogra>
ah, k
08:38
apt-get install --reinstall ltsp-server
08:38
check inetd.conf afterwards
08:39
<masus>
ok
08:39
http://pastebin.ca/705881
08:39
the new inetd.conf
08:40
after --> apt-get install --reinstall ltsp-server
08:41
maybe i have to install another tftpd server
08:41
<ogra>
tftpd-hpa
08:41
should be a dependency of ltsp-server anyway
08:41
<masus>
tftpd-hpa - HPA's tftp server this is teh one i have
08:42
nothing changed in inetd.conf
08:46Gadi has joined #ltsp
08:51
<masus>
i'll make again a fresh installation :)
08:51
again again until it works :D
08:54
<ogra>
no
08:55
dpkg-reconfigure tftp-hpa
08:55
that should give you the entry if you answer yes to the question about inetd/standalone
08:56
s/tftp-hpa/tftpd-hpa/
08:56
then build the client ..
08:57
<highvoltage>
ogra: have you ever considered replacing dhcp3-server with dnsmasq? It has a build-in tftp server too
08:58
<ogra>
highvoltage, nope
08:58
we have one dhcp server in main which i use ...
08:58
and we wont drop that one in favor of dnsmask ...
08:59
neither will we support two
08:59
<highvoltage>
ah, right
08:59
<masus>
ok
08:59
<ogra>
there is an example config shipped in the ltsp docs in case you want dnsmasq
09:00
<highvoltage>
nice. I just thought it would make it easier to support if you could replace two programs with one
09:00
dnsmasq is also easier to configure (and reconfigure)
09:00
(and provides easy dns caching, site blocking, etc)
09:00
<ogra>
it would make it totally not easier for sure
09:00
<highvoltage>
oh wow, really?
09:01
<ogra>
guess how many people wound just install dhcp3-server because the docs for the old releases say so
09:01
<highvoltage>
ah yes, absolutely.
09:01
<ogra>
and then end up with broken tftp for example
09:01
<highvoltage>
yes, that would be terrible.
09:01
<masus>
ogra: tftpd-hpa or tftp-hpa
09:02
<ogra>
tftpd-hpa
09:02
<masus>
u have wrote this one dpkg-reconfigure tftp-hpa
09:02
and i hace installed
09:03
tftp-hpa
09:03
is it a problem
09:03
<ogra>
no
09:03
thats the client
09:03
nothing to care about
09:04
reconfig the daemon as well :)
09:04
<masus>
ok after reinstall dpkg-reconfigure tftpd-hpa nothing change in inetd.conf
09:04
reconfig
09:04
<ogra>
dpkg-reconfigure tftpd-hpa asks y question
09:04
*asks you a
09:05
<masus>
yes
09:05
<ogra>
what did you answer ?
09:05
<masus>
should teh server stated by inetd
09:05
yes
09:05
<ogra>
right
09:05
that should add a stanza to inetd.conf
09:06
<masus>
"dpkg-reconfigure tftpd-hpa / Stopping HPA's tftpd: in.tftpd. / Starting HPA's tftpd: in.tftpd."
09:06
<ogra>
huh ?
09:06
not if you answer yes
09:06
<masus>
http://pastebin.ca/705911
09:06
this is the last inetd.conf
09:07
<ogra>
something more fundamental seems to be broken in your system
09:07
<masus>
maybe i write it manual
09:07
<ogra>
if you say yes to that question, update-inetd is run and the stanza is added
09:07
well, that would work around the issue, but not fix it
09:08
your issue seems to be that debconf doesnt do the right thing
09:09
wait for vagrantc, he maintains the debian port, no idea what debian did here
09:09
<masus>
"#Defaults for tftpd-hpa / RUN_DAEMON="yes" / OPTIONS="-l -s /var/lib/tftpboot" "
09:09
<ogra>
tftpd-hpa usually defaults to be run by inetd ...
09:09
<masus>
in /etc/defaults/tftpd-hpa
09:09
<ogra>
its weird that it doesnt for you after install
09:10
so something is really wrong here
09:10
<masus>
hmm
09:10
<ogra>
vagrant will be able to tell i guess
09:10
<masus>
ok i'll wait
09:10
thanks
09:10
<ogra>
run your ltsp-build-client meanwhile :)
09:10

vagrantc: just got a client running 5.0.27debian1~0.fg.1 on etch running. But, no X, and the chroot is just 400M, while my 5.0.8debian3 chroot is about 500M.

feisty was a bit over 300M
10:47
(thats gutsy above)
10:47
500M is just obscene :)
10:47
<vagrantc>
we just use xorg, rather than picking out individual font sets and such
10:48
<ogra>
yeah, i'll probably switch that back
10:48
even though that was a massive speedup
10:48
it doesnt affect the nbdroot anymore
10:48
<vagrantc>
though the 400M vs. 427M is probably a better comparison

seeing as it's more similar versions

Hi... I had to recompile the kernel for some ltsp clients on Fesity to get a new NIC card supported (driver is not included on the ubuntu releases), but after I install the image on the ltsp chroot client complaints that modules.dep is not found.... anyone have an idea of what I'm missing?
10:52
<vagrantc>
klausade: that's with etch, right ?
10:52
<klausade>
vagrantc: yes.
10:52
<ogra>
jmbp, you didnt use module-assistant and built it as module ?
10:52
jmbp, i guess best is then to ask in #ubuntu-kernel, that message has nothing to do with ltsp
10:53
(and we ususally dont touch kernels in ltsp :) so expetise might be better over there)
10:53
<klausade>
vagrantc: the buildline I just used is at http://paste.debian.net/37675. Trying to use a line as close to the original debian-edu as possible. not sure if that is a good or bad thing.
10:55
<jmbp>
ogra: no, i didn't use the module assistant... i was suggested to recompile the kernel including the driver, but i wonder that that will be easier... I have tested the driver on the live cd and works fine, but I dont know how to just build that driver for the ltsp chroot on Fesity... any ideas?
10:55
<ogra>
never ever compile a full kernel (at least in ubuntu) to just get a NIC driver :)
10:56
<jmbp>
ogra: yes, I was wondering that I've choosen the hard way... :(
10:56
<vagrantc>
klausade: that should work, as good as one can expect, anyways
10:57
<klausade>
jmbp: can't you just add the module to /opt/ltsp/i386/etc/initramfs-tools/modules and rebuild the kernel in the chroot with linux-image, and then run ltsp-update-kernels outsiude the chroot?
10:57
jmbp: thats how I did it when I need sky2 for a new client.
10:59
<vagrantc>
klausade: i should try the backport with a static X config ...
10:59
<ogra>
s/linux-image/update-initramfs -u/
10:59
<vagrantc>
klausade: just to see that everything else works...
10:59
<klausade>
ogra: yes, probably better, been a while since I had to do that, and my memory ....
11:00
<vagrantc>
klausade: it's working good on sid and lenny, so far
11:00masus has joined #ltsp

11:00
<ogra>
klausade, i dont think we have linux-image in ubuntu at all :)
11:00
(as command)
11:01
masus, looks good :) your PXE prob is fixed
11:01
<masus>
:)
11:01
<vagrantc>
klausade: but i really think a decent etch backport will get us some good feature testing from those who aren't willing to run lenny or sid
11:01
<ogra>
masus, now add the nfsroot parameter as i told you in the very beginning
11:01
to override the broken root-path
11:01
<masus>
no i havent add it
11:02
can u write again
11:02
<ogra>
in your pxe config add nfsroot="<ip>:<path>"
11:02
the same you have in dhcpd.conf for root-path
11:02
<masus>
ok
11:03
option root-path "10.0.0.1:/opt/ltsp/i386";
11:03
uthis one right ?
11:03
<ogra>
masus, i told you all you have to do ... scroll back to the beginning of the conversation

11:05
<masus>
:) ok
11:05
<ogra>
vagrantc, masus uses etch btw
11:05
<vagrantc>
ah, yes.
11:06
masus: you're probably encountering: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=387808
11:06
masus: which wasn't fixed until after etch released
11:07
and the fix was so simple...
11:07* vagrantc kicks vagrantc for not figuring it out sooner
11:07
<vagrantc>
masus: but why don't you just use next-server instead of putting the ip address in root-path ?
11:08
<masus>
i use next-server in dhcpd.conf
11:08
next-server 10.0.0.1;
11:09
option root-path "10.0.0.1:/opt/ltsp/i386";
11:09
<vagrantc>
masus: so just use: option root-path "/opt/ltsp/i386";
11:09
<masus>
hmm
11:09
<vagrantc>
much simpler.
11:09
<masus>
ok i'll try
11:09
<jammcq>
next-server is for tftp, not for nfs
11:09
<vagrantc>
jammcq: that's not how we've interpreted it.
11:09
<jammcq>
oh?
11:09
<vagrantc>
jammcq: and that's not how the in-kernel nfsroot code handles it
11:09
<jammcq>
the initramfs has some logic to use next-server for nfs ?
11:10
hmm, ok
11:10
<masus>
be right back
11:10
<jammcq>
news to me
11:10
<vagrantc>
jammcq: initramfs, as well as linux kernel
11:10masus has left #ltsp
11:10
<jammcq>
I consider the in-kernel nfsroot to be dead, as linus has threated for years to yank it out
11:11
<vagrantc>
well, sure, but i see it as the existing convention
11:11
<jammcq>
ok
11:11
<vagrantc>
and it's been threatened for years and managed to stay in
11:11
<ogra>
thats not the whitepaper behavior though
11:11* vagrantc remembers the days of compiling kernel after kernel with nfsroot support
11:12
<ogra>
next-server by definition doesnt define anything for nfs
11:12
<vagrantc>
it defines a boot server
11:12
<ogra>
for tftp
11:12
<vagrantc>
is it explicitly tftp only ?
11:13
i was pretty sure it said boot server.
11:13
<ogra>
if initramfs-tools really uses it for nfs, thats wrong ... but i wont chnage it unless users complain :)
11:13
well, define "boot"
11:13
<jammcq>
"boot server" to me means where to get a kernel from. not what to mount as a root fs
11:13
<vagrantc>
no less wrong than assuming next-server is the same as the dhcp-server
11:13
<jammcq>
but hey, if it works, i'm all for it
11:14
<ogra>
++
11:14
<vagrantc>
hard to boot without a root filesystem
11:14
<ogra>
why
11:14
if you shut down your nfs server you do that all the time :P
11:14
<jammcq>
you could boot memtest. it doesn't need a root fs
11:14
<vagrantc>
ah, whatever.
11:14
<jammcq>
:)
11:14
<ogra>
initranfs is a root fs :P
11:15
<vagrantc>
ogra: you use next-server in ubuntu all the time, you just hide it from your users.
11:15
<jmbp>
klausade: how do I re-build the kernel in the chroot?
11:15
<vagrantc>
ogra: and your code is dependent on it.

ogra: thanks...
11:20
ogra: general question should be: how to add a module to ltsp kernel image on Feisty...
11:20* vagrantc wonders what's the difference between "filename" and "option bootfile-name"
11:20
<vagrantc>
bootfile-name isn't supported by bootp ...
11:21
the manpage for dhcp-options claims that some clients actually require it
11:21
maybe those obnoxious intel clients fit that category
11:21
<ogra>
jmbp, you use your distros kernel tools to build a module

18:02mistik1_ is now known as mistik1
18:10
<vagrantc>
Uranellus: correct.
18:11
<Uranellus>
hm .. but I could distinguish, by checking wether $DISPLAY contains localhost or is empty .. then it's "probably" ltsp 5
18:11
<vagrantc>
right
18:12
if [ -n "$SSH_CONNECTION" ] && [ -n "$DISPLAY" ]; then LTSP5 ; else FOO; fi
18:13
to do it the other way .. .though you might encounter situations where you're not running LTSP then ... i.e. you ssh -X into the box from a non-ltsp environment
18:21
<Uranellus>
vagrantc: do you know how $DISPLAY would look like if one is connected through xdmcp (ltsp 4.2) ? sry, don't have a possiblilty to test right now (I'm at home)
18:25
<vagrantc>
Uranellus: $hostname_or_ip_address:0.0
18:25
<Uranellus>
but not localhost right?
18:25
<vagrantc>
no, if you logged in locally it would usually be just ":0.0"
18:26
or something like

I guess that'll do it ..
19:07
<vagrantc>
the [[ ]] work ?
19:10
<Uranellus>
I guess so
19:10
the problem is: ssh -X would pass on the first if

ah!

if [ -n "$LTSP_CLIENT" ] && [ -n "$SSH_CONNECTION" ]; then LTSP5

you can't get the ip address from $LTSP_CLIENT, but i *think* the variable should only be present if it's LTSP5

Evening all

19:41
sbalneav: notice anything odd ?
19:43
<sbalneav>
No
19:43
The one in init mkdirs the /var/run/drives, the other starts the daemon later in the process
19:44
If you'd like to merge them all in to one, we can.
19:44
Seeing as how one of them doesn't do all that much other than a mkdir.

<jimcooncat>
can I set up an xnest on my standalone computer, and get a user screen on the LTSP server?
19:46
<sbalneav>
Actually, with the new C cdpinger, I call add_fstab_entry, which does a mkdir -p on /var/run/drives/mount, so really, come next release, we could drop the mkdir altogether, as the first media mounted would make /var/run/drives.
19:46
jimcooncat: Probably. I've never tried.
19:47
<jimcooncat>
want to know how to initiate a connection, please
19:48
<sbalneav>
Don't know, off the top of my head.
19:48
Tried google?
19:48
xnest and ltsp return some hits.
19:50
<jimcooncat>
I tried earlier, as now. All I see are questions, no answers...
19:50
I'm wondering if I'd be better served by a standalone, but the light clients work so well...
19:51Uranellus has left #ltsp
19:51
<jimcooncat>
so that's why I come to the source
19:52
I'm unsure how I could vnc into it, but I suppose I could start vnc while in a session, and leave it open?
19:53
I can't see why it would be a netboot or nothing situation, don't people have remote access?
19:56
I tried doing a netboot through qemu running on my machine, but it looks like I didn't have a recent enough version from the Fiesty repositories
19:57
<vagrantc>
sbalneav: yea, i like the sounds of the new cdpinger stuff
20:02
<sbalneav>
I gotta fork off a new tree this weekend, get that and the new jetpipe in there.
20:04
<jimcooncat>
sorry sbalneav didn't know you was interested thank
20:05
<sbalneav>
ok
20:05
well, here's the quck and dirty way
20:06
gross, but workable
20:06
On your
20:06
display box
20:06
Do a:
20:06
Xnest -ac :1
20:06
That'll open up the xnest server
20:06
<jimcooncat>
ok that would run xnest without access on display 1
20:07
<sbalneav>
now, ssh into your other server
20:07
<jimcooncat>
without access control that is
20:07
<sbalneav>
and do a:
20:07
DISPLAY=<firstmachineip>:1 /etc/X11/Xsession
20:07
<jimcooncat>
ok, got that
20:08
but does that get me into the machine proper, or into the LTSP chroot environment?
20:09
<sbalneav>
It'll give you a session on the remote machine in the xnest window.
20:09
<jimcooncat>
maybe chroot first, then run the Xsession? that might work
20:10
<sbalneav>
WHat do you need the chroot for?
20:10
You said you wanted to use Xnest on one machine to get a session on the other machine.
20:10
the chroot doesn't enter into it.
20:10
that's only for the thin client.
20:10
<jimcooncat>
I want to have the same screen as if I booted from one of the thin clients -- isn't that a different environment?
20:11
<sbalneav>
no
20:11
that gets you exactly the same thing
20:11
<jimcooncat>
oh god I was confused
20:11
<sbalneav>
except in an xnest window.
20:11
<jimcooncat>
shoot, thank you, I would have done that if I wasn't barking up the wrong tree here
20:12
I thought I would have different apps available and /etc
20:12
<sbalneav>
no
20:13
logging in on a thin client's exactly the same as logging in on the console.
20:13
<jimcooncat>
then I must have been looking at the files that just run the thin clients x server
20:13
<sbalneav>
you'll get the same apps, etc.
20:13
<jimcooncat>
you've been a world of help, I can get on with it now. thank you sbalneav

<joebob777as7_>
hey so if i wanted to install nvidia restricted drivers would i just chroot into dir and install normally?
22:52
<sbalneav>
Should, although I've never installed the nvidia drivers, I've never had an nvidia card
22:52
So I can't say for sure.
22:54
<joebob777as7_>
also how do i make it so the amd64 clients boot correctly and the i386 clients boot on the same server?
22:54
<sbalneav>
As usual, the answer is: why not try it and see? :)
22:54
<joebob777as7_>
yeah i'm just an hour away from my server now and wanted to know. ;)
22:55
<sbalneav>
You'd have to serve out the amd64 image on a different port than the i386 image, and set pxe boot options for the amd64 clients to set nbdroot=<ip:port>
22:56
But really, even with 64 bit clients, you won't get much speed improvement over running them in 32 bit mode.
22:56
Your network's the limiting factor.
22:56
<joebob777as7_>
ok so it'd be fine to run them all on i386?
22:58
<sbalneav>
As thin clients, yeah. I mean, past a certain point, your network becomes the speed limiter.
22:58
<joebob777as7_>
do you know if there is a driver white list anywhere? because when i tried to run compiz it says that the driver is not whitelisted
