<uniconformist>
vagrantc: do you know if i could use webcams on client machines?
04:21
<vagrantc>
uniconformist: i do not know.
04:24
uniconformist: your best bet is to run an LTSP5 implementation and run all applications locally.
04:29
<genjix>
You people should come to our conference! http://crystalspace3d.org/main/Main_Page ;)
04:40pere_Zzzz is now known as pere
04:44
<uniconformist>
vagrantc: when you say locally, do you mean the server?
04:44
<vagrantc>
uniconformist: no... not logging into the server at all. running your window manager and all applications on the thin client
04:44
uniconformist: to get your webcam working
04:45
uniconformist: though installing the webcam on the server is an option, if you only need one webcam
04:46
<uniconformist>
vagrantc: what do you mean by "window manager"? i'm thinking you'd need to log into the server from the terminal and therefore have capabilities to run apps and use hardware on the terminals.
04:47
vagrantc: unless that's what you mean.
04:47
<vagrantc>
uniconformist: ok ... so usually, you log into the server and run all your applications on the server itself.
04:47
<uniconformist>
yes.
04:48
<vagrantc>
uniconformist: if you want to use a webcam attached to the thin client, you should run all your applications on the thin client instead of the server.
04:48
that's the easy way.
04:48
<uniconformist>
yes.
04:48
strange how that works. using hardware on terminals with apps from the server.
04:49muh2000 has joined #ltsp
04:50
<uniconformist>
so it's like loading a servers harddisk into RAM, then using RAM to get to local hardware by having local RAM access hardware locally.
04:51
sorry to sound technical.
04:51
technicality for simple objectives.

<vagrantc>
ogra-classmate: not cloop?
11:09

11:11
<cliebow>
how goes the fiight??
11:11
<vagrantc>
ogra-classmate: it is a complicated concept.
11:11

ugh
11:15
<cliebow>
rjune is the Man
11:15
<william>
how can i find out
11:15
<rjune>
cat /etc/fedora-release IIRC
11:16
GNOME or KDE, what do you have the sound server set to in lts.conf?
11:16
<cliebow>
like esd or nasd?
11:16
rjune:nice to have you here..
11:17

11:17fernando1 has joined #ltsp
11:19
<william>
it is set to nasd
11:19
i however have tried both
11:20
<cliebow>
william:did you lok on the wiki for rjune's discussion?
11:20
<william>
where is that at
11:20
<rjune>
what is 6 zod?
11:20
<william>
my verision
11:20
<rjune>
william: http://wiki.ltsp.org
11:20
ah, ok.
11:20
<william>
version even
11:20
<rjune>
you using KDE or GNOME?
11:21
<william>
i use kde the kids use gnome
11:21
<cliebow>
http://wiki.ltsp.org/twiki/bin/view/Ltsp/Sound
11:21
<rjune>
You'll want to use ESD for your backend, you may have to rebuild arts to support esd backend
11:22
<william>
and how do i do that
11:22
<rjune>
grab the arts srpm, and rebuild it with esd and esd-devel installed
11:23
<cliebow>
rjune:is that the old rpm --rebuild trick?
11:24
<rjune>
cliebow: rpmbuild --rebuild
11:24
<cliebow>
ah yes..that sakes my cage
11:25
ah yes..that shakes my cage...
11:25
<william>
lmao
11:25
so all i need to do is redownload arts and it will rebuild
11:26
<rjune>
you'll need to install esd and esd-devel. then grab the srpm and rebuild it.
11:26
it's not an automatic process
11:26
<william>
how do you rebuild it
11:26
sorry i am new to this
11:27
<rjune>
rpmbuild --rebuild SRPM.RPM
11:27
<william>
k
11:28
i will try it
11:31McDutchie has quit IRC
11:33
<william>
k in the package manager i don't see eds devel
11:34
esd even
11:35

<lindi->
do you now a way to benchmark "desktop responsiveness" in thin clients? http://iki.fi/lindi/xblink.c updates the display quite slowly under VNC (with 100Mbps ethernet), tcpdump shows that the data is transmitted fast so I'd like to figure out where the viewer is spending its time
12:10
(i'd like to have a simple and stateless thin client software solution i could run on 300-800MHz x86, and VNC seems to be the nicest for this)
12:12
<cliebow>
nx??
12:12
<lindi->
cliebow: yes but how do i benchmark it?
12:13
clearly i'd first like to know what causes the slowdown with VNC
12:13
and i've already ruled out lack of bandwidth
12:14
<cliebow>
i am unclear what you are doing..but cant help with benchmarking..what does vnc havve to do with thin client per se
12:14
<lindi->
cliebow: vnc is just one approach to do it?
12:15
<cliebow>
rather than x on the clients and an nfsmount?
12:15
this is ltsp?
12:16
<lindi->
cliebow: X isn't stateless, if there's a power outage on the client programs will die
12:16
ah, i thought ltsp was generally about free thin client solutions
12:17
xdmcp and nfsroot are cool things though
12:17
<cliebow>
yes...our formula involves netboot and x on clients with nfs mounted root filesystem...you'd better talk to jammcq when you can
12:18
we 9ogra) has an ldm in lieu of xdmcp.you can use either there for login
12:18
<lindi->
i use such a setup at work but didn't read about ltsp when i configured it
12:19
i'm probably going to use netboot with vnc viewer too since hard disks are just useless here
12:19
cliebow: anyways, xdmcp would benefit from a benchmark suite too
12:19
<cliebow>
want to look over wiki.ltsp.org..it might get a handle on this project..
12:20
the big guns are ubuntu dev sonference so the channel is awful quiet
12:21
<lindi->
i've found a research paper on benchmarking VNC but it only looks at network traffic
12:22
<cliebow>
lind-:sosrry i cant he;lp you there...in ltsp4.2 clients boot in under 30 seconds..never thought about benchmarking beyond that
12:23
ltsp5 will have dramatic speed improvrments\\
12:23
in time
12:24
<lindi->
cliebow: when i hit alt-2 to switch to another workspace i can clearly see how the graphics is updated from top to bottom
12:24
it's at least 100 ms
12:24
<cliebow>
in vnc..rigght
12:24
<lindi->
yep. xblink tries to make this easier to reproduce
12:25
<cliebow>
it ltsp there is minimal lagtime..even on a p133
12:25
<lindi->
is there any way to sniff what xvncviewer talks to the X server over unix socket?
12:25
cliebow: can you test xblink on that? ;)
12:25
compare against remote and local execution
12:25
<cliebow>
maybe tomorrw at work..
12:26
<lindi->
ok, no worries
12:26
<cliebow>
hmm i dont see xblink..int apt or on my macvhine
12:27
<lindi->
http://iki.fi/lindi/xblink.c
12:27
it just alternates between black and white background
12:27
<cliebow>
ahh i see
12:28
<lindi->
very artificial of course but that's what basically happens when i switch workspaces
12:29
<cliebow>
keep an eye out for sblaneav or jammcq they are 6 hours away from EDT..in sPain..

Hello, I was planning a large LTSP deployment and had questions about limitations of LTSP.
13:34
Some of the issues may be distro related
13:35
But I was wondering how many clients can LTSP support?
13:38
<japerry>
damntech: LTSP doesn't have any client limitations really
13:38
damntech: its limited by your hardware
13:39
<damntech>
Ok great.
13:39
I work for a School District, they want to acheive 1 to 1 where desired by instructor.
13:40
We have a HS with 2500+ students
13:40
I couldn't imagine more than 1500 of them accessing the servers.

I have already tested LTSP under the K12LTSP and Edubuntu distros on a DellXPS laptop and 8 clients simultaneously accessed our webbased educational resources, no sweat. The websites used embedded Quicktime, Flash and Java.

damntech: if you need quicktime and flash, ltsp probably isn't the best solution for you
13:52
<damntech>
Yeah that's what I wondering
13:52
<rjune>
which state?
13:52
<damntech>
how will it scale
13:52
<sep>
damntech, for regular office/web usage i can run 40-50 clients on a dual xeon with 4GB ram, but that drops to 10 if they use falsh or java based things
13:52
and it depend a _LOT_ on the quality of the flash/java
13:52
<rjune>
you mean how many terminals can your server support?
13:52
<sep>
some flash things on webpages sucks bigtime. while others play quite nice
13:53
so how many you can use at the time depends greatly on the quality of the flash/java programmer that made the flash/java in question.
13:54
<rjune>
You'll also run into bandwidth problems
13:54
<damntech>
These are educational apps sometimes they vary
13:54
<sep>
damntech, we use a combination of ltsp for ligth tasks. and diskless workstations for heavier tasks
13:54
<rjune>
320 x 240 x 16 x 30 == a fair bit of bandwidth
13:54
<sep>
damntech, yes they vary a lot. and they and not suited for ltsp
13:55
<damntech>
Ok diskless workstations? How has this worked for you sep?
13:56
<sep>
quite well.
13:56
but ofcourse there are some webbased edu apps that require activeX (the fuckers!!)
13:57
<damntech>
actually I had made sure none of ours do.
13:57
<sep>
generaly the problem is allways non compatible applications. that the teachers have never heard about but they "MUST HAVE"
13:57
<damntech>
We have only purchased cross platform apps
13:57
<sep>
even tho it runs on windows only
13:57
and there are 3 equal or better FOSS versions.
13:57
it's the windows version they need
13:58
damntech, here in norway the goverment have a lot of services available
13:58
and it's not all cross platform
13:58
<damntech>
Yeah, I know thats why we are looking at adding linux to our services and likely making it central to all our services
13:59
We were mainly aming for low maintence solutions
14:00
we deployed >300 machines this year and will deploy even more next year. We havent got the humanresources for that
14:00
everyone wants 1 to 1
14:01
but it costs +2000 per endpoint after computer, network, server.
14:01
<sep>
damntech, well with diskless workstations the clients pxe boot, and use the server as their harddrive
14:01
<damntech>
That's what I was looking at about a year ago
14:01
but got into this ltsp thing
14:01
Ok great
14:02
have any suggestions
14:02
<sep>
that means all aplications start across the network
14:02
you need some bandwith
14:02
<damntech>
we can handle it
14:02
<sep>
for ltsp you require 2Mbit/sec for each client. and it must be low latency
14:02
<damntech>
we have 1G and 10G to core
14:02
<sep>
i do that by having a separate switch for the ltspserver->client network's
14:03
and i scale by adding a new server and a new switch with 40 new clients
14:03
that way the network server-> clients is predictable to avoid lag.
14:03
<damntech>
Ok, have say 1 server per wing 300 endpoints?
14:03
<sep>
then you'd need lots of cpu and ram on the server
14:03
:)
14:04
<damntech>
yeah I don't care how we acheive it. I just want to get there.
14:04
on the diskless systems you suggest is there any hardware vendows that worked well for you?
14:05
<sep>
we use all kinds of stuff
14:05
as long as the linux kernel have the hardware support it just works
14:06
<damntech>
Yeah, I was just looking for a starting point.
14:06
<sep>
damntech, depends if you want support or not :)
14:07
i user debian so i like hp
14:07
but i dont use support so *shrug* we run all kinds of hardware
14:07
<damntech>
Ah, yeah we were becoming wooed by ubuntu
14:08
<sep>
well that's ok.
14:08
ubuntu is based on debian so i can't see any large difference in hardware support
14:09
i use debian-edu
14:09
it's debian preseeded for schools
14:09
<damntech>
Ok, Ill check that out.
14:10
<sep>
damntech, but with ltsp you can have 50 clients in a classroom with 0 noice using embedded devices. that's quite a cool feature imho
14:10
with diskless workstations they still need to be workstations with the hardware management that needs.
14:10
you might also look at FAI
14:11
<damntech>
Yeah, every lab we have deployed required power upgrades and ac upgrades costing over $20,000
14:11
<sep>
that way you have 100% workstations but automatically installed and configured thru FAI
14:11
damntech, with ltsp you can get quite low power devices
14:11
damntech, here too.
14:13
<damntech>
Our deploys have been fast with apple and ms quick deploy tools. I have been monitoring tools like kickstart and fai
14:14
<sep>
damntech, i deploy windowsxp using RIS and unattended from our debian-edu servers too.
14:14
have a list of mac addresses that get a optin in the pxe boot meny to install windows xp localy.
14:15
those machines dualboot linux diskless workstation or windows local boot
14:16
<damntech>
Wow, thats a great idea.
14:16
<sep>
those that are not in the list pxe boot as diskless workstations only
14:18
<damntech>
On your diskless systems is there a non ltsp option to utilize local processing and ram?
14:19
<sep>
umm.. ? i dont understand the question..
14:19
you mean like a compute cluster ?
14:20
<Q-FUNK>
like workstations using nfs root but runing applications locally
14:20
<damntech>
Yeah
14:20
<sep>
all the diskless workstations does that
14:20
that's what i mean when i say diskless workstation
14:20
it's nfs root and local cpu/ram/processes.
14:20
<Q-FUNK>
as opposed to thin client (ltsp)
14:21
<sep>
yes
14:21
<damntech>
Ok, that's sounds like the direction I should be heading since multimedia will chew up resources
14:22bobby_C has joined #ltsp
14:22
<Q-FUNK>
it can still be etherbooted. the main difference is that a thin client would only bootstrap an XDMCP client, while a diskless workstation would boot a kernel capable of mounting root over NFS.
14:23
or well, it wuld bootstrap a whole OS over NFS
14:23
<damntech>
Yeah just needs a swift line to access it's NFS
14:23
<Q-FUNK>
same client device, different bootstrap image served by the boot server.

anyone: do i need 2 ethernet cards to run LTSP?
15:57

hiho, usualy yes.
15:57
it's atlest easier that way.
15:58
<hiho>
i have a network of 30 pcs and apples, and i want to add dozens of ebox-2300's or alike, how would i do that? (thanks!)
16:00
the pc's and apples are using a ms smb file server
16:01
the ms server does dhcp
16:06
<damntech>
Since DHCP decides where PXE goes you would have to configure the DHCP server to select a different PXE boot server. Do you RIS or utilize apple imaging?
16:07
<sep>
i use RIS
16:07bobby_C has quit IRC
16:07
<sep>
you can send each mac to a different pxe in dhcp.
16:07
<damntech>
ah.
16:08
<sep>
but personaly i have only 2 pxe. 1 with rip+diskless and 1 with diskless only. dhcp decide if a host is a windows capeable or not machine
16:09
s/rip/ris
16:09
<damntech>
Oh ok.
16:12
<hiho>
so i can put a static ip on a single ethernet LTSP server, and tweak the MS DHCP server to point PXE on a mac addr basis?
16:15
<damntech>
I am doing it in a MS/Apple environment. sep is doing it in a MS/linux environment. Sounds about right.
16:15
<sep>
hiho, usualy the ltsp server have 1 nic on the LAN with the other machines. and 1 nic on a dedicated separate switch with all the ltsp clients on it
16:15
the ltsp server have dhcp for the ltsp clients
16:15
and the ltsp server may (or mayt not) recive dhcp from the main network dhcp server
16:15
damntech, yes

Gosh I was just crunching numbers price wise. A 16 way server with 32GB ram in worse case senerio as described by rjune would support only 80 devices.
16:43
but thats a $20,000 server
16:44
<sep>
damntech, whats the worst case scenario ?
16:44
i usualy scale by more servers then one huge one. but my users are distributed so its a geografical question too
16:45
<damntech>
rjune said he had a 2way server with 2GB ram and only when people accessed poorly coded java, flash etc... only 10 users will work reasonabley
16:47
<sep>
damntech, yes i see the same thing
16:48
<hiho>
damntech: what is the bottleneck, cpu? memory?
16:48
<damntech>
I would guess memory Java/Flash
16:48pere is now known as pere_Zzzz
16:49
<damntech>
I actually had good results with our supported apps
16:50
I had a Dell XPS laptop with 1 GB ram and I pulled up four webbased apps which used java and flash on 8 clients and they were going full steam with no problems.
16:50
<sep>
damntech, yes it's all depending on the app
16:51
damntech, but many of the apps around here is lousy. and some of the flash based adds on common newspapers is crippeling
16:51
<damntech>
I am assuming that it scales linearly with things like java/flash since they're not the best linux apps
17:02
I guess the TCO for LTSP, minus human resources and power consumption, is practically $500-$1000. Which is half to a quarter of what we are spending right now. HR and power consumption are likely to decrease.
17:05
Ill probably just grab an 8 way system with 16GB and run 70 terminals to see how it goes.
17:05
<sep>
let us know :)
17:06
<damntech>
I will. Thanks for the knowledge. bye.
17:06
<cliebow>
damntech:my old junk is coasting like 5 bucks per terminal; plus labpr 8~)
17:07
<damntech>
Yeah, I know we aren't shooting that low
17:07
People are demanding that certian apps are universally accessible
17:08
1 to 1 where ever someone wants it
17:09
but we dispose of equipment at a linearlly increasing rate, close to matching the purchasing rate. the IT depts human resources are becoming drained.
17:10
we will either stay the path and double our staff and take more out of the classroom. its getting real tight because spending got real loose.
17:11
any how. I think this can change alot for us. we can cover the all needs and many wants.
17:11
well back to what I was doing. thanks again.
