<markit>
Empiric: I don't know, I'm not an expert, just curiosity... "some of my thinclients".... are them different in hardware / config?
00:04
<Empiric>
ya
00:04
they are
00:04
basiacally are of them r local machine
00:05
machines
00:05
its only 3
00:05
any idea how i fix them
00:05
i have defined X_MODE_0= 800x600
00:06
X_MODE_1=1024x768
00:06
but no use
00:06
how i check my thinclients are reading lts.conf
00:09
<markit>
I've no idea, sorry
00:09
what about not setting it at all? should find the best resolution automatically
00:09
but what do you mean with "blinking"?
00:10
the image is ok but is going on and off? or is distorced / ruined?
00:12
or check a good value pair for the X_HORZSYNC parameter
00:13
or you can force the video chipset, if it does not recognize it automatically, like with XSERVER = via
00:13
if you have a via one (or ati...)
00:13
I mean, if you have ati, write "ati" instead :)
00:14
in any case, the X-Window SERVER is run on the client side, so google to find how to see how to know what setting is it using
00:23
<Empiric>
yes its going on nad off
00:23
can u hhave exact things whete i put X_HORXSYNC
00:27
<markit>
what do you mean? look at your monitor hardware specifications
00:28
if you are asking me what values use
00:28
Empiric: where are you from? are you an asterisk pbx expert?
00:33
<Quintin>
is there an LTSP client that runs on top of win32?
00:36
markit: blinkenlights! woot
00:38
<markit>
Quintin: blinkenlights ?
00:38
<Quintin>
markit: blinkenlights!
00:38
<Empiric>
hai
00:38
<Quintin>
Empiric: hi2u
00:38
<Empiric>
why u r asking that?
00:44
markit
00:44
?
00:48fxrsliberty has quit IRC
00:50
<markit>
Empiric: because I have troubles understanding your english, and because I see "asterisk" in your irc signature
00:51
<Empiric>
ok
00:51
i have some thinclients
00:52
<markit>
yes, you told me
01:00
wondering if Empiric is a secret agent, that can't answer my previous questions...
01:00
<Empiric>
which when boot starts bliking
01:01
well sory i was on phone
01:01
where i put X_HORIZSYNC
01:02
<markit>
well, where are the other X options for that specific client
01:02
of course in lts.conf
01:05
like
01:05
[ws008]
01:05
# ATI Card with ViewSonic P815 21" monitor running at 1800x1440
01:05
#
01:05
X_MODE_0 = 1800x1440 250 1800 1896 2088 2392 1440 1441 1444 1490 +HSync +VSync
01:05
X_HORZSYNC = 30-115
01:05
X_VERTREFRESH = 50-160
01:05
or better sampel for an LCD
01:05
[ws009]
01:05
#
01:05
# 17" flat panel. Had to add the X_HORZSYNC, otherwise it would do only 1280x960
01:05
#
01:05
X_MODE_0 = 1280x1024
01:05
X_HORZSYNC = "60-70"
01:06
(info taken from internet, or from some other ltsp documentation, don't remember)
01:11
<Empiric>
i have 15' LCD
01:12
hai i have no entries in /etc/hosts
01:17
so what i do
01:27
<markit>
get an installation guide, I'm not expert, and to be sincere, is long time I don't look at ltsp
01:28
but don't think that /etc/hosts is needed
01:28
and don't know how it could be related with your video blinking, no?
01:28
if you specify IP in your configs, hosts is not necessary, I guess
01:35
<Quintin>
so, I got this ltsp-server thingie installed
01:35
is there a LiveCD with the client?
01:36
<markit>
Quintin: to boot? you need a PXE or whatever boot rom in your ethernet adapter, or prepare a floppy boot, as far as I remember
01:37
better check the documentation :)
01:37
<Quintin>
markit: ewwwwwwwww I just want it to werk :P
01:37
there is some PXE crap when I power up this computer
01:40
<markit>
if you have correctly configured dhcp, it should find it and load the OS from the ltsp server
01:40
and boot
01:40
dhcp on the server side,of course
01:46
<Quintin>
duhhhh
01:46
I have a diff box that is dhcp server...
01:53
hum
01:53
couldn't a livecd using remote X login replace all this ltsp stuff? :P
01:56
<neuralis>
Quintin: sure, if you want to manage 50 cd-rom drives and 50 cds for your 50 terminals.
01:58
<Quintin>
neuralis: cd's never fail. unless you do something dumb like put a bunch of stickers on one side. cd-roms almost never fail
01:58
er, cds, not "cd's", oops
01:58
<vagrantc>
Quintin: CDs fail *way* more often than boot roms.
01:59
most network cards support PXE these days- it's a simple matter of turning it on.
01:59
<Quintin>
my test client box supports PXE, yes
02:00
but why setup all these services etc.. when I can just boot a livecd and login with x.. seems to be more work
02:00
<vagrantc>
anything that is easily removable will be removed. and people will want to put their audio CDs in, and wonder why everything stopped working...
02:00
Quintin: if you think it's easier with a livecd, implement it with a livecd :P
02:01
i'll stick to network boot, thank you very much.
02:01
<Quintin>
so how well does something like playing a movie work with this?
02:03
Not Found
02:03
The requested URL /documentation/index.php was not found on this server.
02:03
lame! :\
02:05
the prices on some of these 'thin clients' are enough to buy a whole regular PC
02:07
<vagrantc>
are they the fanless kind?
02:07
<Quintin>
nope
02:07
<vagrantc>
tend not to break down as much without any moving parts.
02:11
<Quintin>
hmmm
02:11
maybe you are all crazy :p
02:12
<vagrantc>
yeah. thousands of happy users can only be wrong.
02:13
<Quintin>
all depends on what you are doing
02:13
probably more useful for 100 seat net than 10 seat
02:13
<vagrantc>
i tend to find the usefulness at about 3 seats, myself.
02:15
as it's essentially one computer.
02:15
<Quintin>
you didn't answer my question.. how is playing video .. ??
02:16
can something like that be done effectively? or is there too much network overhead ?
02:16
<vagrantc>
video can be hard if you're using encrypted connections. sometimes the remote sound gets messed up. but you can also run movies using local applications.
02:17
like many things, it depends
02:17
<Quintin>
local applications?!
02:18
<vagrantc>
yes- running some or all of the applications on the local hardware, rather than the server.
02:18
<Quintin>
that sort of defeats the purpose doesn't it? can that be automated? the making applications local bit
02:20
<vagrantc>
if all the machines are using the same root filesystem, you only still are essentially managing one installation for however many seats.
02:20
and what do you mean by automated?
02:20
<Quintin>
well the clients don't have disks.. so how can the app run locally?
02:21
<vagrantc>
the same way they run at all.. over the network.
02:21
<Quintin>
I'm lost :)
02:21
<vagrantc>
but the applicaion is using the local machines CPU and RAM.
02:22
but the filesystem is over the network.
02:22
does that clear it up?
02:22
<Quintin>
sort of. how would you make the app use local resources instead of server resources?
02:22
<vagrantc>
there are numerous ways to set it up.
02:23
<Quintin>
here is a probably very silly question
02:23
<vagrantc>
the simplest, is to just run all the applications locally, and just have your server be a file server.
02:24
<Quintin>
mmhm..
02:24
here is question showing my ignorance, eh :P
02:24* vagrantc waits only slightly patiently
02:24
<Quintin>
let's say you have app xyz, that uses 16m of core. 100 users have it open .. server uses 1600m of ram?
02:25
<vagrantc>
only if it's a very poorly written program.
02:25
<Quintin>
well I made it, so.....
02:25
<vagrantc>
most programs in linux use shared memory
02:25
<Quintin>
but let's say it's GAIM. or k3b. or or or .. firefox
02:25
or opera. that's a good one
02:26
<vagrantc>
it varies widely, but generally each additional instance of an application is only an additional 5-20% RAM used.
02:27
<Quintin>
mmm
02:27
to do a basic network boot... there is transfer of like 5m or so, ja? in setup as you describe, to have all things run locally and have the server used only as file server.. how much data is transferred when booting?
02:28
<vagrantc>
though firefox is prone to wasting lots of memory ...
02:28
<Quintin>
firefox on linux = sux
02:29
<vagrantc>
hmmm... well, a traditional thin-client eats maybe 5-20MB at boot.
02:30
but if you start to add applications running locally, it will entirely vary based on the size of the application.
02:30
<Quintin>
can you recommend any thinstations with usb and cdrom or dvdrom?
02:31
<vagrantc>
i generally just use recycled equipment
02:31
so i don't have a lot of recommendations for buying stuff.
02:31
<Quintin>
mmm
02:31
what kind of setups have you done with ltsp?
02:31
<vagrantc>
i know disklessworkstations.com actually supports ltsp development pretty directly.
02:33
<Quintin>
mmm
02:33
?!
02:33
<vagrantc>
my main installation was done at freegeek ... about 20-50 machines at a time. though that was all using lessdisks, which is very similar. i've started merging my efforts into ltsp.
02:34
we also did small 3-terminal installs at coffee shops and stuff.
02:34
i did a small computer lab at a school
02:34Egyptian[Home] has joined #ltsp
02:34
<vagrantc>
i know in norway, there are schools with hundreds of computers running ltsp
02:35
and there's telecentres in brazil with many seats as well.

Quintin: well, i hope ltsp works well for you, despite your doubts. or that you find something that works better for you.

Hm... I figured out why my ltsp server wasnt working but now i'm trying to do somthing else, but dont know how
10:28
I'm trying to use LTSP as a Point of Sale server.
10:28
<chupacabra>
im looking for some gpl POS software
10:29
<surferdude>
ditto, i'm going to try and code one myself
10:29
<chupacabra>
k that is what I been thinking after grokking about
10:29
but first, naptime
10:30
<surferdude>
what i want to be able to do is when a client connects to the server and logs in, i want to be able to connect to their X screen
10:31
i know theres a way to do it on the server

Maybe.
11:39
(TODO: Ask.)
11:39
my crystal ball was broken last night
11:40
<aa>
I am trying to configure LTSP Server on a Knoppix Live CD. I started the knoppix-terminalserver
11:40
And when it comes to Checking DHCP Connection it fails It says
11:40
Sending DHCP broadcast from device eth0 Operation failed
11:40
I start the client using Etherboot Floppy It Says Searching for Server(DHCP).... NO IP Address
11:40
Well The DHCP itself fails
11:41
What can be the reason?
11:41
<vagrantc>
does etherboot find the network card?
11:42
<aa>
yes It finds the network card
11:42
as if the LAN wire is not attached to the Other PC it gives error saying cable wire problem
11:42
<vagrantc>
any log messages on the knoppix machine?
11:42
/var/log/syslog
11:42
or other files in /var/log/
11:43
is the dhcp server running on the knoppix machine? ps aux | egrep -i dhcp
11:43
<aa>
well on the server it says "Sending DHCP broadcast from device eth0 Operation failed"
11:46
actually i tried this at my office and I am using this bot from Residence and so can't say the output of the command
11:46
The entire problem is listed at http://pastebin.ca/264710 Can you provide me the various ways to solve the same
11:48
<vagrantc>
knoppix terminal server is weird. i'm not real familiar with it, but i don't think it's even really LTSP
11:50
<aa>
it is ltsp
11:50
<vagrantc>
aa: this is just a guess, but try a new network card on the server? or a new switch/hub?
11:50
i think it may be *like* ltsp, but i'm pretty sure it is not ltsp.
11:51
<aa>
I am not connecting this to any hub/switch I am connecting it directly from the PC to PC
11:51
and in the knoppix you can try ltspconfig and ltspadmin
11:51
<vagrantc>
with a crossover cable?
11:51
oh, perhaps i was mistaken, then.
11:51
<aa>
yes I think so as I had used the same cable for Windows to Windows networking
11:51
<vagrantc>
it used to be it's own weird thing.
11:52
so, i have demonstrated that i really know nothing about knoppix terminal server. :)

hello. Does anyone know if kernel 2.6.17 already come with Boot splash implemented or do I need to re-compile Kernel to do it? Thanks
18:55
<vagrantc>
you'll need to recompile or use a user-space bootsplash alternative.
18:57surferdude has quit IRC
18:57
<gargula2005>
user-space? The best I could do was a boot splash during bizintroimage charge, but it disapears when kernel starts.
18:58surferdude has joined #ltsp
19:05
<vagrantc>
the user-space tools i know about are called usplash and splashy. pretty debian/ubuntu-specific.
19:06

Anyone here familiar with upstart?
19:31
<vagrantc>
only in the sense that it sounds cool.
19:32
<PMantis>
heh
19:33
<cliebow>
PMantis:Just a howdy!
19:33
<PMantis>
hi cliebow
19:33
<cliebow>
what are you working on?
19:34
<PMantis>
My LTSP server is now a fresh install of Edgy, except using LDAP auth.
19:35
However, upstart brings up udev before slapd - causes udev to hang for a *long* time, and other headaches before I can *finaly* get a console and start them in the right order.
19:35
<cliebow>
oh yeah..there have been some bug reports..
19:36
one way is to do a soft
19:36
err
19:36
<PMantis>
So far, I've received no response in #ubuntu, and many comments in #ltsp - even if it's just to say 'Hi'.
19:36
...typical. :)
19:37
<vagrantc>
ubuntu's so easy to use, it must be user error.
19:37
<cliebow>
i just went thru this in edgy..with ldap
19:37
soft
19:37
hell cant remember
19:37
lemme lok
19:39
bind_policy soft in /etc/libnss-ldap.conf
19:40
udev may also faial
19:41
<PMantis>
vagrantc, Thanks for the vote of confidence. :)
19:42
<cliebow>
libnnss-ldap is def a major stumbler
19:42
<PMantis>
I never made that change to the school server
19:42
Both were scratch edgy installs
19:43
Wonder what the difference is.
19:44
<cliebow>
i know just what you mean..it never bothered my laptop
19:45
anyway...i can look in my server upstairs if you need a cross chevk on anything
19:46
#edubuntu is SO much more useful
19:48
oh yeah the other hack was to addd a user nvram
19:48
oh yeah the other hack was to addd a group nvram
19:48
sorry
19:48
https://launchpad.net/distros/ubuntu/+source/libnss-ldap/+bug/67404
19:52
<PMantis>
heh
19:52
thanks, I'll look
19:57
Well, I'll change to soft for now - school server is not plugged in so I can get at it.
19:58
Can't test right now though - wife using a thin client.
