[14:17] <inoex135> hi all
[14:17] <inoex135> i want to ask some tips how to increase the speed of my ltsp
[14:18] <inoex135> i use amd 64 bit with 1 Gb memory and 5 client
[14:21] <ogra> 1gig is pretty low for 5 clients with full desktop at the same time
[14:22] <inoex135> ogra, but i read in the requirement
[14:22] <ogra> (depending on what your users do indeed )
[14:22] <inoex135> edubuntu just need 128 Mb for each user
[14:22] <ogra> well, its 128M x number of clients + 256M for the server
[14:23] <ogra> whats slow for you ?
[14:23] <inoex135> yesterday all of the client run tuxmath :D
[14:23] <inoex135> and the tuxmath run so slowly :((
[14:23] <ogra> yeah, thats a design issue of tuxmath ...
[14:24] <inoex135> i don't know, is it right that when the users run same aplications will make the system run slowly?
[14:24] <inoex135> because when they run different aplication, the system run faster
[14:28] <ogra> is that with a certain application ?
[14:28] <ogra> or with all of them
[14:39] <inoex135> not with office
[14:39] <inoex135> because i implement in school
[14:39] <inoex135> the students just use tuxmath and some game like chess
[17:17] <stgraber> RichEd-1: Good news from iTalc, italc's author contacted me by jabber and really seems to want to help debugging it
[17:23] <laga> ogra: i think i have found a workaround for the unionfs nfs bugs. create a ext2 image on the nfs share and mount that. haven't tried it yet, though :)
[17:26] <ogra> laga, well, then you can as well take squashfs and nbd :)
[17:26] <ogra> plus ext3 image for the writable pieces
[17:27] <ogra> (i wouldnt use ext2 )
[17:28] <laga> yes, that's the plan. or do you mean i should use nbd for the writable pieces as well? that's a bit more complicated because you can't easily create new images then
[17:28] <laga> i'd ideally use one image per client
[17:28] <laga> ogra: ext3 sounds good as well
[17:28] <ogra> have a look at nbdswapd
[17:28] <ogra> it creates the swap files/images on the fly
[17:29] <laga> yes, i've already done that. i don't see how i can easily create a relation between one specific client and its own overlay
[17:29] <laga> (overlay == cow directory)
[17:29] <ogra> you got the ip
[17:30] <laga> ip does not work well in DHCP environments
[17:30] <ogra> but that can change indeed
[17:30] <laga> right now, i use the mac address
[17:30] <laga> which should work pretty well
[17:30] <ogra> usually one client gets the same ip all the time
[17:30] <laga> still not reliable enough :/
[17:30] <ogra> unless you have more clients than IPs
[17:30] <ogra> right, you cant rely on it
[17:31] <laga> i wonder if nbdswapd even "sees" the ip address of the client since it's run from inetd
[18:22] <laga> ogra: daniel holbach posted  i need to go through the usual sponsor ship process for getting my patches included into ubuntu. do you still plan on applying them or should i do was i was told?
[19:06] <ogra> laga, you dont i clearified that
[19:06] <ogra> he just goes blindly over all bugs that have patches attached
[19:06] <laga> ogra: great.
[19:07] <ogra> the locales patch will be in the next upload ...
[19:07] <laga> ogra: it looks like i'll get a proper unionfs patch as well.
[19:07] <laga> <- happy. :)
[19:07] <ogra> :)
[19:09] <laga> ogra: do you want the other patches in one big patch or broken into several smaller patches?
[19:10] <ogra> depends how big that big one is
[19:10] <laga> good answer. i'll try to go easy on you ;)
[19:11] <ogra> sorry, but i have to leave now for a company dinner ...
[19:11] <ogra> ets talk about the other one tomorrow
[19:11] <laga> have a nice night
[19:49] <Goosemoose> hi guys, has the addon for hardy been finished to enable the simple authentication against an AD domain?
[20:15] <Delcastanher> Hello!
[20:15] <Delcastanher> I need some help with LTSP
[20:15] <Delcastanher> anyone can help me?
[20:15] <laga> just ask a question :)
[20:16] <Delcastanher> is it possible to use an USB Printer on thin client?
[20:16] <Delcastanher> im googling it all day :P
[20:19] <Delcastanher> knock knock?
[20:19] <laga> relax.
[20:19] <laga> if someone has an answer, they will answer
[20:19] <johnny> i assume it should work in theory
[20:20] <johnny> never tried tho
[20:20] <Delcastanher> i read that its possible... but looks like it needs the lp_server package
[20:21] <Delcastanher> and it package is not in repository
[20:21] <johnny> lp_server.. i've never even heard of that
[20:21] <johnny> i figured cups would take care of it
[20:21] <johnny> just like it does for everything else printer related
[20:22] <Delcastanher> as i read, the server's cups will access the client's printer... but the client needs the lp_server running
[20:24] <Delcastanher> look:
[20:24] <Delcastanher> http://ltsp.mirrors.tds.net/pub/ltsp/docs/ltsp-4.1-en.html#AEN696
[20:26] <johnny> edubuntu doesn't use ltsp 4
[20:26] <johnny> in any recent release
[20:26] <johnny> afaik
[20:26] <johnny> you can't really count on any ltsp 4 docs
[20:28] <Delcastanher> but i didnt find anything about ltsp printing at ubuntu docs, or wiki...
[20:29] <johnny> well.. that is a problem for sure
[20:29] <johnny> but you still can't use ltsp 4 docs in any case
[20:29] <johnny> the design is totally different
[20:33] <Delcastanher> yes... i think i will google everything again...
[20:33] <Delcastanher> i found something now: http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/customizing-thin-client.html#id529611
[20:34] <johnny> yeah.. the handbook is good
[20:34] <Delcastanher> but i think that i tried it before... but ok... i will try again :)
[20:34] <johnny> if it doesn't work.. check the bugs on launchpad
[20:37] <Delcastanher> thank you! i will reboot my thin client now.
[20:37] <Delcastanher> wish me luck :D
[20:41] <Delcastanher> you are right
[20:41] <Delcastanher> ltsp 5 is not 4.1
[20:41] <Delcastanher> :)
[20:42] <Delcastanher> the only thing i change: use mac address between [ ] instead use ip or machine name...
[20:42] <Delcastanher> now is working
[20:42] <LaserJock> great
[20:45] <Delcastanher> thank you very much
[20:45] <Delcastanher> and good night (it is night in Brazil) :P
[20:46] <johnny> night
