I'm having troubles with my network printers not being available in all local applications on my thin clients. Is there a way to make a printer globally available to local applications?
08:49rjune has quit IRC
08:50
<alkisg>
The only relevant thing I know is that when I have a printer connected to my server, to make that printer available to my ltsp-based fat clients (==localapps), I need to go to the printer's configuration dialog on the serer, then on the menu server > settings, and check "Publish shared printers connected to this system".
08:50
This way the clients auto-detect the printer, I don't need to do something on them.
08:51
<grey-monkey>
I'll try that. Thanks

stgraber: would we care (=upstream) for an ltsp-build-client plugin that automates NFS /home sharing with fat clients/localapps? http://paste.ubuntu.com/396721/
09:28
(I guess not, everyone hates NFS, just asking.. :))

it was 10 years ago today that Legal Aid Manitoba deployed an LTSP desktop

12:11anivair has joined #ltsp
12:12
<anivair>
real quick, does anyone know if the thin clients from disklessworkstations.com use full duplex?
12:12
I can't get mii-tool to run locally
12:12
so askibng is the next best option
12:13
(specifically, I'm looking at the term 1220
12:13
)
12:19
<abeehc>
ethtool?
12:21
<anivair>
that won't work because I need root permissions to use it. I don't have admin rights on a local terminal
12:22
(ie: if I run it on a localapps xterm window, I can't run ethtool because I can't run it as root (no display) and I can't sudo (no sudo)
12:23laron has joined #ltsp
12:24Lns has joined #ltsp
12:25
<laron>
is there a good ltsp client graphicall manager?
12:25
<alkisg>
like iTalc?
12:26
<anivair>
what it seems like I really need is a way to check to see if a given thin client is using full duplex. right now I've got nothing
12:26
all I know is that the server is
12:27
which doesn't help when running things on the thin client
12:30
really, it's a permissions issue. I don't have admin privelidges on hte localapps
12:30
so there's not much i can do that touches the nic
12:31
<Lns>
anivair: why not create a script during bootup to tell the server somehow (append to text file?) ?
12:32
or simply log into tc chroot
12:32
<anivair>
you lost me
12:33
you mean create a script to tell me at bootup whether or not they're using full duplex?
12:33
<alkisg>
anivair: put SCREEN_02=shell in lts.conf
12:33
This way you'll get a root shell in the client
12:33
<anivair>
good call
12:33
<alkisg>
Then you can run mii-tool or ethtool etc..
12:34
[Default]
12:34
SCREEN_02=shell
12:34
SCREEN_07=ldm
12:34
<Lns>
alkisg: why not just ctrl+alt+f1? Isn't there always a client shell there?
12:35
<anivair>
there is, but no login
12:35
<alkisg>
Lns, he'd need to unlock the root account to login there
12:35
set a password, update the image etc... more difficult
12:35
<anivair>
will i need to reload the kernel after editing lts.conf? or just reboot?
12:35
<alkisg>
Just reboot
12:35
<Lns>
alkisg: this just dumps you into a shell itself?
12:35
<alkisg>
(the client)
12:35
Lns, yup
12:36
<Lns>
..wow
12:36
didn't know that one!
12:36
<alkisg>
Hey!
12:36
How did you debug problems so long?! :)
12:36
<Lns>
I never really had many on the clients.. =)
12:36
<alkisg>
OK, then maybe I should also tell you the secret lts.conf setting to get a 10x speed boost... :D
12:36
<Lns>
and I always set root pw anyway
12:36
alkisg: hahaha
12:37
surely you mean LTSP_10X = True
12:37
to force 100mbit cards to 1Gbit, right?
12:37
like overlocking
12:38
overclocking*
12:38ogra_cmpc has quit IRC
12:38
<alkisg>
Yup, and also FORCE_GLX=True which enables 3d hardware acceleration on all cards...
12:39
<Lns>
nice one
12:39
personally I like LTSP = ponies..for magical ponies to dance around at random times

Thanks, that worked like a charm

(though ltsp = ponies was less successful)

(though it did look good next to my SOUND_DAEMON=bubba entry)
13:05
<Lns>
=p
13:05
<anivair>
that last one is not a joke, either. I like ot think of it as a little present for the person who replaces me here someday.

What's the standard way to mix client images and configure dhcpd.conf to act according to client arch?
13:21
In https://help.ubuntu.com/community/UbuntuLTSP/LTSPCrossArchSetup - I see a way to configure for ppc vs. i386, possibly I can rework the wiki page to reflect this with AMD64 also (since atom thin clients are amd64)

I'm having another go at the Xnest "problem" on ltsp5. For me, it certainly doesn't work, just the black window mentioned in various web posts. Just now I have been able to get an exported desktop using sabayon but it just gives the default ubuntu desktop, not the xterm clients's fluxbox desktop. How might I get this X forwarding working without an ancillary app?

I have also set the Dissallow TCP stanza in /etc/gdm/gdm.schemas to False.
13:44
<laron>
how can i view the individual client's ip address? from the server and locally on a client?
13:46
<Lns>
laron: from the client you can log into the chroot (by lts.conf having a "SCREEN_02 = Shell")
13:47
<laron>
ok
13:48
<alkisg>
Here's a script which outputs the clients mac address and ip address (assumes ubuntu/nbd): http://paste.ubuntu.com/396863/
13:49
<Lns>
alkisg: do you run multiple arch chroots?
13:49
<alkisg>
Lns, nope
13:49
<Lns>
darn
13:49
<alkisg>
I don't even use dhcpd :)
13:49
<Lns>
seems nobody does..i want to get ahead in the 64-bit client game and figure out how to run multiple chroots side by side
13:50
<alkisg>
Lns, I don't think dhcpd can detect i386 vs amd64
13:50
<Lns>
specially since localapps/fatclients could benefit from it
13:50
<alkisg>
There's a new pxelinux.0 that can do that, though
13:50
<Lns>
alkisg: i've been looking into vendor-class-options and friends for dhcpd..haven't found much
13:50
<alkisg>
It's still alpha/beta something, but if you want to be ahead of the game, you might give it a try...
13:50
<Lns>
oh really
13:50
<alkisg>
Lns, an i386 will have the same nic as an amd64, afaik
13:51
<Lns>
alkisg: oh that's just for the nic?
13:51ogra has quit IRC
13:51
<alkisg>
So code is needed to be executed on the client to know if it's i386/amd64
13:51
So you need pxelinux.0 for that
13:51
<Lns>
alkisg: you have any links for the new pxelinux.0 ?
13:52
<alkisg>
No, I've read it somewhere by hpa, but I don't have the URL
13:52
Try his site first..
13:52
<Lns>
ok, thx for the info

found this on the k12ltsp wiki: K12LTSP is considered to be LEGACY software that is usable with old hardware until CentOS5 support ends in the year 2014.
14:11
will any other distros be doing the same?

alkisg: sure
14:35* alkisg would prefer a .vmdk disk for that :D
14:36
<Lns>
that would be cool too =) or .dd.gz? =p
14:36
<alkisg>
.vmdk ==> boot the fat client image directly with vbox and install/configure whatever...

Hello..!!! all
15:12
<sbalneav>
Hello
15:12
<epaphus>
In order to PXE i need to buy a supported PXE NIC and aside from that my BIOS should support it?
15:17
<alkisg>
epaphus: or you can use gPXE
15:17
!gpxe
15:17
<ltspbot>
alkisg: "gpxe" :: the successor to etherboot (http://etherboot.org). To download bootable floppy, cd, usb, kernel etc images, visit http://rom-o-matic.net/
15:17
<epaphus>
right.. but i need true pxe
15:17
<alkisg>
It's true pxe, it's just on a different medium
15:18
But yeah, other than that, you'd need nic + bios
15:18
(or a good nic with embedded bios)
15:18
Or if your nic is flashable, you could flash gpxe on it
15:21
<epaphus>
thanks
15:22
What happens when I connect a USB pendrive to my thin client?
15:22
nothing?
15:22
<alkisg>
When do you mean?
15:22
When the client is working?
15:22
<epaphus>
Yeah.. lets see i booted using PXE...
15:22
and i connect a usb pen drive
15:22
<alkisg>
If you've enabled LOCALDEVS, the user there can see the contents
15:22
If not, nothing happens.

<Ahmuck>
is there still a problem with sound in ltsp on client hardware? i've tried a gateway with an intergrated sound card, and it fails, and i've tried a dell with a soundblaster, and it fails
19:02
however, a virtualbox vm works fine
19:05epaphus has quit IRC
19:10
<johnny>
Ahmuck, not generally
19:10
did you try it without ltsp
19:10
and a plain distro?
19:10
that would tell you that it is probably not ltsp related at all..
19:10
unless you have proof
19:10
but you should assume it is the distro's fault
19:10
before ltsp
19:11
<Ahmuck>
it does work without ltsp
19:11
we have windows installed on the hard drives as backup
19:11
boot to windows, sound works
19:12
this is ubuntu. yes, it may be the distro's fault, as one has an intel i8xx chip for intergrated sound which i've uncovered as an issue. from reading iirc, ubuntu unloaded that chipset module from the kernel
19:12
however, the other machine is standard sound blaster
19:13
last evening for the first time, i got to see ltsp actually work correctly. however this was not on older hardware (as advertised by many ltsp zealots) but rather a less than a year old apple laptop running a vm
19:18
<johnny>
standard soundplaster is super old
19:18
who knows if modern kernels still include such drivers
19:18
who knows if the driver is even maintained anymore..
19:19
Ahmuck, remember.. ltsp folks have no control over hte kernel
19:19
you have to take such issues up with your distro
19:19
if you have a hardware problem.. make sure it works in the same version of ubuntu or other distro
19:22
<Ahmuck>
assuming that ltsp will run in 128mb ram on a client, i don't think any modern ubuntu distro will run in that
19:22
<johnny>
i think there is some lxde spin perhaps..
19:35slidesinger has joined #ltsp
19:36
<abeehc>
Ahmuck: they call it xubuntu
19:37
<Ahmuck>
to run ltsp properly then out of box, one needs modern thin client hardware
19:37
<abeehc>
nope
19:38
if you go as far as localapps, yes
19:38
but really it'll boot on these p3 machines i have here with 128mb ram
19:38
<Ahmuck>
Once installed, Xubuntu can run with starting from 192 (or even just 128) MB RAM, but it is strongly recommended to have at least 256 MB RAM.
19:38
<abeehc>
that has nothing to do with ltsp
19:38
it's simply a better baseline
19:39
than "sound works in windows"
19:39
<Ahmuck>
*shrugs*
19:39
<johnny>
the point is just to test the sound Ahmuck ...
19:39
the problem is probably not related to ltsp, but the distro kernel Ahmuck ..
19:39
don't blame it on ltsp until you're sure it's ltsps fault
19:39
<Ahmuck>
yes, ubuntu ltsp channel is edubuntu, and it really has nothing to do with edubunt either :(
19:39
<johnny>
and?
19:40
<Ahmuck>
and it's not your fault ...
19:40
<johnny>
there's also #ubuntu .
19:40
or #xubuntu
19:40
once you determine it is the fault of ubuntu or not
19:42
<abeehc>
anyway there's really no problem with ltsp sound it works better than i'd like in some cases
19:42
and i'm using intel integrated sound
19:43
intel 828
19:43
<Ahmuck>
ya, i won't bother troubleshooting it.
19:43
i'll just pick up some beefeir thin clients from newegg

having a problem with the tftp file not found on pxe boot
22:19
I'm an LTSP newbi
22:19
On ubuntu 9.10
22:23
<johnny>
do you already have a dhcp server elsewhere on your network?
22:23
if so.. the proble is that you need to tell the dhcp server to point to your ltsp server
22:24
<Matthew_>
yes. And I have.
22:25
<johnny>
so.. you have next-server ?
22:25
from another computer.. you should consider installing a tftp client
22:25
and try fetching the file yourself
22:25
<Matthew_>
I have pfsense router. i've enabled network booting on the router, pointed it to the ip of my ltsp server.
22:25

hmm.. well.. i couldn't tell you whether it's doing the right thing or not

tftp client... how do I tell what port my tftp server is serving on?
22:26
<johnny>
never used pfsense
22:26
you don't need to know the port.. the default should work
22:26
<Matthew_>
thanks for your willingness to help.
22:26
sorry, I meant IP. I have more than one NIC
22:26
<johnny>
it should be serving on all
22:26
<Matthew_>
okay. Thanks.
22:26
<johnny>
i think anyways..
22:27
<Matthew_>
I tried both IPs and got the same error
22:27
<johnny>
same error?
22:27
<Matthew_>
It would start the pxe boot then say tftp file not found (something similar to that)
22:27
the client would do that.
22:28
<johnny>
sure.. but get a tftp client program on one of your other computers
22:28
<Matthew_>
I seem to have everything installed correctly on my Ubuntu server
22:28
<johnny>
and try to talk to your server
22:28
<Matthew_>
okay.
22:28
<johnny>
tftp <ip>
22:28
or whatever the program is called
22:28
but also..
22:28
do you have
22:28
on your server: /var/lib/tftpboot/ltsp/i386/pxelinux.0 ?
22:29
you must have that first.. :)
22:29
<Matthew_>
yes. I do have that.
22:30
that's the file I should be entering into my router, right?
22:30
<johnny>
not the full path
22:30
<Matthew_>
ahhh!
22:30
<johnny>
are you sure you need a path ?
22:30
<Matthew_>
what should be entered then?
22:30
<johnny>
nothing i don't think..
22:30
if pfsense uses isc dhcpd
22:31
<Matthew_>
nothing? Just blank?
22:31
<johnny>
then it would have next-server <serverip> in the generated config
22:31
is pfsense in front of your ltsp box?
22:31
if so.. it could just be a firewall issue
22:32
if not..
22:32
<Matthew_>
both the client and the server are behind the pfsense router on the same subnet
22:32
<johnny>
see if you can paste the generated config
22:32
or whatever dhcp server it is running
22:32
as i have no idea what maps to watch in pfsense
22:32
s/watch/what/
22:33
<Matthew_>
what filename should I paste into the router config? It says I need both a filename and a server to work.
22:33
<johnny>
i have a feeling it's talking about something different
22:33
but i can't tell without having an idea of what the pagel ooks like
22:33
can you find a screenshot?
22:34
/me is assuming you're talking about a web interface
22:35
<Matthew_>
I'm looking for a screenshot. Yes, it's a web interface.

sbalneav, for you too.. neat huh
22:36
<anivair>
quick question (for those that know a thing of three about networking):
22:36
<johnny>
or 4 :)
22:36
i know 4 things :)

I am running some network speed tests on my system. I get much faster times on my own machine than i do running the same speed test (speedtest.net) on a thin client. This happens even when they are in the exact same port on the same switch.
22:37
Is that normal?
22:37
<johnny>
did you also use the same cables?
22:37
are the network cards the same?
22:37
do you mean running speedtest.net from a logged in thin client session? or from the thin client itself?
22:38
<anivair>
the former
22:38
<johnny>
ah
22:38
<anivair>
froma client session
22:38
<johnny>
so.. really it's on the server
22:39
<anivair>
yes. but I'm wondering if the ltsp traffic on the server nic is known to slow down that sort of test
22:39
<johnny>
so.. you did the test while the logged in users were active at all? or not?
22:39
logged in client users*
22:39
<anivair>
not. this is the only thin client on the network
22:40
<johnny>
well.. try running it locally on the server .. while the thin client session is active
22:40
make sure your results aren't poisoned

seems likely that it has nothing to do with ltsp
22:40
just that your network is generally active while you're on the client..
22:40
<anivair>
thanks

johnny: I figured out my problem. thanks for putting me on the right track.
22:49
It was the filename that I had wrong.
22:49
It needed to be just "ltsp/i386/pxelinux.0" instead of the full path.
22:50
<johnny>
there ya go
22:50
good going
22:50
enjoy
22:51
<Matthew_>
It's pretty sweet!
22:52
I'm running a laptop as a client, but the server has 8 GB of RAM. Seems to be working great.
