vagrantc: why do the Vcs-Browser fields use launchpad instead of the loggerhead on alioth?
16:49wwx has quit IRC
16:49
<vagrantc>
Ryan52: because they were put in before loggerhead was in alioth
16:50
<Ryan52>
ah :)

<petre>
so, I've been away from ltsp for a bit and forgotten everything I knew. To add a package, can I just chroot to /opt/ltsp/i386 and then use yum or rpm to install the package for the client (this is on fedora)?
18:44
<stgraber>
hi petre
18:44
yes, it should work, in some cases you may need to mount bind /dev /proc and /sys too but it's not always required
18:45
<petre>
hey stgraber, how are you?
18:45
<stgraber>
very good and you ?

<petre>
doing well, but busy at work these days so not much time for ltsp :-(
18:51
the good news is the work is fun: building a customized livecd respin of Centos.
18:52
I see people are gearing up for LTSP By the Sea again.
18:53
Sadly, I don't think I can make it this year, no vacation time or money.
18:57
hmm, no vi in the chroot
19:28cliebow has joined #ltsp
19:41
<nubae>
wow loggerhead is a cool little known app
19:41
how awsome to publish your bzr branch via the web so easily

19:44adrien has joined #LTSP

<adrien>
hello, can someone help me with some connection issue?
19:47
i'm trying to have some windows workstations to connect to the internet through LTSP server at my school, but with no luck. I tried everything I could find in the doc but nothing seems to work
19:49
they get an ip address from the LTSP dhcp server fine, we can share files using samba, but the connection to the internet is not working (while it's works perfect for the thin clients connecting to the server)
19:50
is there something special to do or is it just impossible?
19:55
can someone read me?
19:56
<Guest72697>
you need to setup nat
19:57
the thin clients don't need nat since they are actually using the servers connection
19:57Guest72697 is now known as johnny
19:57
<johnny>
but usually this isnt' a good time for this channel adrien
19:57
most people aren't here
19:57
in fact.. i'm usualy not even at this time
19:58
you just got luck
19:58
<adrien>
ok thanks, this is my first time I was'nt sure people could read me
19:58
<johnny>
yes.. just most people are only here on weekdays
19:58
during "business hours" of europe and usa
19:58
<adrien>
I tried to set up nat with an iptable rule, but I'm not sure I'm doing the right thing
19:59
<johnny>
well your distro might include a tool that makes it easier
19:59
than trying to do it manually
19:59
<adrien>
I tried this through webmin
19:59
<johnny>
probably not the best tool either
20:00
<adrien>
what do you recommend?
20:00
<johnny>
i'd suggest joining your distro chatroom
20:00
and asking them the easiest way to setup nat
20:00
for that distro
20:00
some include specific graphical interfaces
20:00
<adrien>
ok, but it is possible then. this is just a nat problem
20:01
<johnny>
yes.. definitely possible
20:02
<adrien>
can you just tell me then which interface needs configuration? I've got eth0 connected to the internet and eth1 to the thin clients and windows workstations
20:06
<johnny>
eth1 needs to forward to eth0
20:07
<adrien>
allright. I'm going to look for some information on the net on how to do that. Thanks for your help!
20:08
<stgraber>
nubae: well, it's the branch viewer developed for and used by launchpad, so not that little known :)
20:09
<nubae>
well little known in the way its used... I guess the code itself is extremely known
20:09
I just didnt know it would be so easy to do that
20:09
<johnny>
adrien, there are simpler tools to make it easy tho.. you should try those first..
20:09
<nubae>
unless everyone is using loggerhead and I'm just not with it yet
20:10
johnny... have u seen my python app?
20:10
<adrien>
thanks johnny, I'll look this way
20:10
<johnny>
nubae, have i told you you are awesome?
20:10
no.. i hven't seen it
20:10
<nubae>
:-(
20:11
<johnny>
just wanted to tell you you that you are awesome
20:11
<nubae>
why the sarcasm, u're usually never sarcastic with me
20:11
:-)
20:11
<johnny>
lol
20:11
i wasn't being
20:11
wanna see a picture i took last summer that i was showing off today? :)
20:11
http://localmomentum.net/~johnny/img_2023-3.jpg
20:12
<nubae>
bzr branch lp:~vcs-imports/pyclic/trunk
20:12
its autobazaared from the sugarlabs git repo
20:12
how cool is that
20:12
ummm... u're train?
20:12
<johnny>
yes
20:13
<nubae>
u totally threw me... I dont know what to think now... its clearly a picture u took.... and then I'm thinking, why would he take a picture of a train...
20:14
unless u're were riding it or something
20:14
<johnny>
why wouldn't i take a picture of a train?
20:14
<nubae>
we're u driving the train? did they let u do that?
20:14
<johnny>
that was a train near a train i was on
20:15
so.. why would i use bzr ?
20:15
when i could just use git?
20:15
<nubae>
dunno, because some people dont like git
20:15
like ogra
20:15
<johnny>
i still don't know why i would ever use bzr over hg
20:15
<nubae>
he refuses to use it
20:15
<johnny>
bzr seems poorly designed
20:15
<nubae>
so just in case, I have both
20:15
<johnny>
you can also pull git from hg too
20:15
<nubae>
I run my git through bazaar for those that want it
20:16
<johnny>
well.. don't show the bzr link by default :)
20:16
<nubae>
I agree, I prefer git too
20:16
I dont know why ogra hates it so
20:16
<johnny>
hg is good too..
20:16
hg > bzr as far as i can tell
20:16
<nubae>
what is hg?
20:16
<johnny>
mercuriral
20:16
mercurial*
20:16
gajim and mozilla projects use it.. among others
20:16
<nubae>
oh, I've heard of that, but never used it
20:17
git is good enough for me, and bazaar I'm forced to use sometimes
20:17
but if I have a choice I create a git project
20:17
just so much friendlier
20:17pmatulis has quit IRC
20:18
<nubae>
though to really understand git... I mean like really get it... that I dont wanna do... someone once tried to teach me at work... I had to spend half a day learning intricacies of git
20:18
god... never again
20:19
<johnny>
you think git is friendlier?
20:19
<nubae>
anyway, my app... just run python pyclic.py, tell me what u think
20:19
<johnny>
even i don't agree
20:19
don't i need other bits ?
20:19
<nubae>
well, I'm just more used to it
20:19
I'd imagine u have pygtk and pycairo installed
20:19
<johnny>
truly
20:19
<nubae>
pango too?
20:20adrien has quit IRC
20:20
<johnny>
yeah.. everything already in a standard gnomeish distro
20:20
<nubae>
then u need nuaght.... though I did just do a commit without testing it...
20:20
heh wait wait
20:20
dont pull yet
20:21
<johnny>
it is asking me for a luanchpad login
20:21
<nubae>
have to fix something I went and commented EVERYTHING today on the bus ride home...
20:21
huh?
20:21
<johnny>
but i haven't changed nothin.. and can still commit to ltsp
20:21
<nubae>
why would it do that?
20:22
<johnny>
i got the revs
20:22
i'm just suprised i can commit to ltsp
20:22* vagrantc held out long enough on trying git that it seems to actually finally be useable
20:23
<johnny>
so.. lemme know when you finish it nubae
20:24petre has quit IRC
20:25
<nubae>
screwed up my indents
20:25
<johnny>
vagrantc, see that pic i mentioned earlier?
20:25
i'm proud of it..
20:26
<nubae>
ok pushed
20:27
<vagrantc>
johnny: wow. that looks like a classic amtrak postcard
20:27
<nubae>
johnny: also did something else I'm really proud of... I used the moodle DB module in a really really cool way, take a look: http://www.linux-for-education.org/mod/data/view.php?id=2747
20:27
<vagrantc>
johnny: only no mountains
20:27
<johnny>
vagrantc, yeah.. it was outside of forth worth
20:27
no mountains there :)
20:27
fort worth*
20:28* vagrantc needs to learn how to open glass doors before walking through
20:28
<vagrantc>
anyways... see y'all later
20:28vagrantc has quit IRC
20:28
<nubae>
vagrantc: I'm gonna make a python to data module for moodle...
20:28
oh, hes gone :-(
20:29
well, I'll tell u then johnny
20:29
its called pydamoo
20:29
<johnny>
no revvs..
20:29
<nubae>
isnt that just the cutest names?
20:29
name
20:29
<johnny>
still
20:29
<nubae>
oh, u pulling through bazaar or git?
20:29
just git clone from sugarlabs.. hang on
20:30
git clone git://git.sugarlabs.org/pyclic/mainline.git
20:30
of course... takes time for the VMS to take the changed git repos and process them into bazaar trunks
20:30
<johnny>
oh
20:30
ok .. that would be smarter
20:31
<nubae>
yeah, so its not immediate immediate
20:31
it all reminds me of Obs...
20:31
these automated services where u have to wait for the VMs to do batch processing
20:31
we're really moving backwards in time
20:32
batch processing is totally back in vogue
20:32
<johnny>
i have no idea what is happening with that thing
20:32
it says open an image
20:32
but none of my images show up :)
20:32
<nubae>
oh wait a png image
20:32
does it not say png image?
20:33
shit... I have to fix the instructions... they are a little off of course
20:33
I spent most of my time commenting code
20:34
oh my god, I just found another total awsome use for my program...
20:35
u know how u have to show steps on how to use shit sometimes... like first click here, then click there, then write in that box, then this one... for complex web apps
20:35
this could totally be used for that...
20:35
I just need to adapt it to spit out a generated image with labels
20:35
instead of what it currently does
20:36
screenshot labeler, heh
20:37
anyway, thats the admin interface for the real thing which is a collaborative quiz
20:37
that works with xmpp
20:37
thats why I generated XML docs out of everything, image included, for easy transport
20:38
the idea is, questions pass from student to student, if u get it wrong, loose 25 points, get it right win 25 points, and for -15 points u can ask for a hint
20:39
scores are stored, and the end idea is there will be lots and lots of quizzes created by teachers who want a quick way of getting their students doing something
20:40
at work I have a demo of a solarsystem quiz, containing all the planets...
20:40
but really there is something for every subject... us creatures are very visual, so these kinda quizzes make sense
20:41
am I now talking to myself or are u still around?
20:41
<johnny>
sorta still here

23:18
<Shinhung>
hello
23:18
<tylerfixer>
howdy
23:18
<Shinhung>
can I get help here?
23:18
<tylerfixer>
most likely, it depends on your question.
23:19
<Shinhung>
is it possible to set up an individual web server per client, each with its own 'localhost'?
23:20
<tylerfixer>
so, you want to run a web server on each thin client, and be able to have the client browse to "http://localhost" and have it be something different for each?
23:20
<Shinhung>
yes
23:20
I've been getting the strangest questions from my clients, that's one of those.
23:21
<tylerfixer>
i'm not sure if you could do it as "localhost", since the "localhost" you'd be seeing would be of the server...
23:21
maybe you could use a script that'd find the IP of the current client and open a browser to the correct location
23:22
or even run a web server on the thin client server that auto-redirects to the ip address of the client somehow
23:22
(not sure how to do that off the top of my head, though)
23:22
<Shinhung>
mm
23:23
<tylerfixer>
yeah, that is a pretty strange question
23:24
you might be able to find the ip address of the connected client through checking the xsession files... a quick bash script to find an ip in the session state files and redirect would do just fine, i think... but a more elegant solution would be better of course :)
23:25
I do have a question of my own to pose to the smarter people than I, however.
23:25
<Shinhung>
what might that be?
23:25
<Guest98031>
hm...
23:25
<tylerfixer>
I have a hp t5520 thin client, and for some reason the cpu usage is always pegged at 100% on the xorg process
23:26
BUT, when I'm at the LDM login screen, the cpu usage is below 1%
23:26
I have tried the vesa driver, the via driver, and the openchrome driver
23:26
they all bring the cpu usage to 100% as soon as i login
23:26
and I do have LDM_DIRECTX set to true
23:26
any ideas?
23:26
<Shinhung>
and stays so even after a while?
23:26
<tylerfixer>
yep
23:26
it's pegged
23:26
<Guest98031>
does your chroot distro version match your host distro tylerfixer ?
23:26Guest98031 is now known as johnny
23:26
<tylerfixer>
nope
23:27
<johnny>
make it so
23:27
it always should
23:27
100% of the time
23:27
<tylerfixer>
haha really?
23:27
<johnny>
yes
23:27
<tylerfixer>
that's so simple
23:27
i didn't even think of that
23:27
<johnny>
you mentioned that
23:27
right before you left last time
23:27
<tylerfixer>
I had downgraded the chroot for some older hardware, but i forgot to re-upgrade it for the new stuff
23:27
<johnny>
last time i was here anyways
23:27
<tylerfixer>
wow, you have good memory
23:27
<johnny>
start it from scratch, don't upgrade
23:27
<tylerfixer>
yeah, i had made a copy of the old chroot
23:27
i'll just rename it back :)
23:28
<johnny>
ok
23:28
Shinhung, why bother running a webserver for each?
23:28
just one one.. and use public_html directories in each ~
23:28
<Shinhung>
I wouldn't
23:28
<johnny>
then they can just browse to localhost/~user
23:28
<tylerfixer>
since i'm not in front of the thin clients right now (I will be tomorrow, however) are there any other ideas if that doesn't work out quite right?
23:28
<johnny>
tylerfixer, not really.. i'm tapped out for now
23:28
<tylerfixer>
okay
23:28
<johnny>
anything else will require you to be there
23:29
in any case
23:29
<tylerfixer>
okay
23:29
thanks again
23:29yanu has quit IRC
23:29
<johnny>
as this is kinda a poke and prod thing now
23:29
<tylerfixer>
yeah, i can't believe I didn't think of that
23:29
<johnny>
well.. you made me realize that we need a script that comes with ltsp
23:29
to capture host distro version, chroot version, and some relevant programs plus specs
23:30
so stuff like this will be easier to come by..
23:30yanu has joined #ltsp
23:30
<tylerfixer>
i think i could write something like that for you if you'd like
23:30
<johnny>
instead of asking all the quetions every time
23:30
well, i'm going to talk to fellow developers about it
23:30
<Shinhung>
I don't understand the part about chroot distro version matching host distro's
23:30
<johnny>
some distros actually have tools
23:30
Shinhung, it's just fact
23:30
don't question it :)
23:30
<tylerfixer>
yeah, for ubuntu you can just cat the /opt/ltsp/i386/etc/issue to find the version of the chroot
23:30
<johnny>
too many possible mismatches
23:31
tylerfixer, but for host distro. there are things like smolt on fedora..
23:31
and something on ubuntu.. i forget which
23:31
<tylerfixer>
i just wonder if xorg is that picky about version to version compatibility on the network
23:31
<johnny>
yes
23:31
seems likely
23:31
at least the way we run it
23:31
but it might not be X at all
23:31
it could be something else causing it
23:32
<tylerfixer>
well, it makes sense I figure
23:32
<johnny>
anyways.. it is the easiest way to match things
23:32
<tylerfixer>
yeah, it's a good suggestion to start off tomorrow
23:32
<johnny>
less variables. the better..
23:32
<tylerfixer>
true
23:32
<johnny>
matching pulse, ssh etc..
23:33
<tylerfixer>
I'm just wondering what was causing the horrendous CPU usage on my geode-based thin clients
23:33
it was almost the same way with them
23:33
xorg at 100% cpu all the time
23:33
<johnny>
well..there are some folks here who know about geode issues
23:33
i'm not one of em
23:33
<tylerfixer>
yeah the more i worked with the geode the less i liked it
23:33
i had to re-write parts of the bios to rid myself of winCE
23:34
<Shinhung>
I plan to order a couple of geode thin clients.. now you're making me think twice
23:34
<tylerfixer>
what speed are they?
23:34
<johnny>
Shinhung, well.. come back and ask the experts
23:34
<tylerfixer>
mine were 300mhz "TCE-100" no-names
23:34
from ebay
23:34
that came with a 8mb DOC and 16mb ram
23:34
<johnny>
my clients are just recycled desktops
23:35
but i wouldn't buy anything with less than 512mb ram
23:35
and > 500mhz
23:35
<tylerfixer>
i agree
23:35
<Shinhung>
lx800?
23:35
<tylerfixer>
i found that out the hard way
23:35
<johnny>
so i could run voip apps and such things
23:35
and FLASH
23:35
the devil
23:35
<tylerfixer>
haha
23:35
<johnny>
flash == evil
23:35
only solution is to run it locally if you want really great performance
23:35
<tylerfixer>
my server seems to handle flash just fine, and so do the clients, but it's typing games that kill them (these aren't the geode clients)
23:36
<johnny>
ah
23:36
well.. my server was kinda overloaded.. sorta
23:36
<Shinhung>
oh yeah I haven't managed to get mic work on the clients. what's the common issue?
23:36
<johnny>
i don't know anything about mics
23:36
those should just work
23:36
it's video/cpu usage that i'm talking about
23:36
make sure they work outside of flash first

oh hey, that made me think of another question I have... (which may be related to my mismatch of chroot and host OS) is that the volume applet in ubuntu doesn't seem to work, it allows me to click "mute/unmute" and change the volume, but nothing changes
23:39
<johnny>
probably not.. but perhaps..
23:39
pulse audio isn't known for it's compatibility
23:40
between versions
23:40Ahmuck has joined #ltsp

<johnny>
in most cases it doesn't matter.. and few user remote pulse anyways
23:40
<tylerfixer>
okay, so that might be fixed when i make the chroots equal?
23:40
<johnny>
as it is easier to stream the actual data (mp3 file) and not raw sound
23:40
<tylerfixer>
that's true
23:41
<johnny>
most people use zeroconf or mpd or whatever for remote music
23:41
on the lan i mean ..
23:41
<tylerfixer>
honestly, it's not a dealbreaker at all, since i suppose i can just turn off sound if i want to mute it (clients have internal speakers)
23:41
<johnny>
well.. see what you get when you try
23:41
and come back
23:41
<tylerfixer>
okay
23:41
<johnny>
once again.. i have no experience here on that
23:41
because i don't even have speakers at my clients
23:41
<tylerfixer>
yeah i'm probably doing something not standard
23:41
<johnny>
so.. the sound might work. it might not.. i have no idea :)
23:42
nah.. i'm doing internet cafe stuff
23:42
with only a couple computers.. sound would make people stick around too lon
23:42
<tylerfixer>
fun fun :) what kind of clients do you use?
23:42
<johnny>
recycled desktops
23:42
donated computers
23:42
<tylerfixer>
very cool, what kind of server do you use for all this?
23:42
<johnny>
most are around 2GHz... but they are all low on ram.. thus ltsp
23:43
my server is dual core 2ghz.. but 2ghz ram
23:43
err 2GB ram
23:43
that's good enough for my 4 pcs..
23:43
<tylerfixer>
nice
23:43
<johnny>
we don't have room for any more
23:43
otherwise we would probably have more..
23:44
it's at a collectively owned and operated bookstore coffeehouse
23:44
of which i am currently a member
23:44
we run ubuntu there.. altho i run fedora at home.. and started the ltsp port for gentoo..
23:44
<tylerfixer>
wow that's awesome
23:45
you've definately got a lot of people using your work
23:45
<johnny>
we just started a freeschool.. perhaps some day i'll put computers there
23:45
<tylerfixer>
once again, linux is awesome :)
23:45
<johnny>
atm.. the structure is too loose to leave computers around..
23:45
people just come to pick up keys.. and bring em back.. whoever is teaching
23:45
so.. nothing expensive is stickin around
23:45
<tylerfixer>
time for some IP cameras?
23:45
<johnny>
we try to avoid such things
23:46
<tylerfixer>
okay, i suppose that brings up things like privacy issues and the like
23:46
<johnny>
we've had thefts from the store.. but only thing CLOSE to that.. is one of those round mirrors in the corner..
23:46
close to cameras i mean..
23:47
<tylerfixer>
i suppose even a fake camera might have some deterrance value

23:49
<tylerfixer>
