| 03:22 | <siji_> hi
| |
| 03:23 | richguit>,goodmorning
| |
| 03:26 | <richguit> siji_: found the pxe probs?
| |
| 03:26 | <siji_> yes
| |
| 03:26 | I fix it
| |
| 03:26 | it's working now
| |
| 03:29 | <richguit> cool :) , did you take a look at the existing knoppix ltsp variants, maybe they contain good ideas for your project?
| |
| 03:35 | <siji_> ok
| |
| 03:35 | but first I just wants to run ltsp
| |
| 03:35 | all the others are ready
| |
| 03:35 | I have to test it only
| |
| 03:38 | <richguit> ok, what was the prob with pxe?
| |
| 03:46 | sep has quit IRC | |
| 04:11 | <siji_> The path of the kernel image was not correct

| 04:56 | <killsalad> hi all
| |
| 04:58 | i've got a problem with sound on a terminal - dell optiplex gx1 which has cs424something card
| |
| 05:00 | durnig startup there is a mesage which says that sound card is busy - is there any chance to run sound on this terminal?

| |
| 07:02 | ey hey
| |
| 07:02 | <Gadi> guten tag
| |
| 07:05 | <jammcq> Bom dia
| |
| 07:05 | Avatara has quit IRC | |
| 07:05 | <ogra> jammcq, !
| |
| 07:06 | jammcq, do you have a common method to test NFS speed properly ?
| |
| 07:06 | i'm juat starting the ltsp-profiling spec and want to list tools/mechanisms to use
| |
| 07:07 | <jammcq> what I did was using my laptop, I have both the Debian and Ubuntu chroot's. I configured dhcpd to cause the thin client to boot debian, and while it was running, I used a stop watch and ran iptraf
| |
| 07:08 | recorded the time and throughput
| |
| 07:08 | then did the same for ubuntu
| |
| 07:08 | i'm thinking there's probably some better tools for doing that
| |
| 07:08 | <ogra> hmm, rather something empiric with no stopwatch involved :)
| |
| 07:08 | <jammcq> well, yeah
| |
| 07:08 | but, ultimately, the user IS the stopwatch
| |
| 07:08 | <ogra> i.e. creating a 10M file with "dd" and measuring with "time" ...
| |
| 07:09 | sure
| |
| 07:09 | but my colleagues will want something like bootchart :)
| |
| 07:09 | <jammcq> that's probably a good test
| |
| 07:09 | <ogra> and mdz too i guess
| |
| 07:09 | <jammcq> bootchart will probably help us alot
| |
| 07:09 | <ogra> well
| |
| 07:09 | so so
| |
| 07:09 | bootchart wont work on 32M systems
| |
| 07:10 | even with 128 it takes about 15mins to create the lng in the end here
| |
| 07:10 | <jammcq> or 256
| |
| 07:10 | <ogra> *png
| |
| 07:10 | (bootchart has a java based converter that maes a png from the raw data after booting)
| |
| 07:11 | <jammcq> whcih machine creates the png?
| |
| 07:11 | <ogra> so testing with bootchart can take a lot of time :) since you cant log in while it generates the chart
| |
| 07:11 | <jammcq> seems like we could take the raw data from the workstation and turn it into a graph on the server
| |
| 07:11 | <ogra> the machine its installed on ... in this case the client ...
| |
| 07:11 | right
| |
| 07:11 | that will need hacking
| |
| 07:11 | <jammcq> might be worthwhile hacking
| |
| 07:11 | dunno what's involved
| |
| 07:12 | if it were perl, I'd do it :)
| |
| 07:12 | <dem> is there any easy way of testing ldm localy on Xnest?
| |
| 07:14 | <ogra> only the greeter ...
| |
| 07:14 | you can cd into /opt/ltsp/i386/usr/shar/ltsp-client/greeters and execute the gtk binary ...
| |
| 07:15 | but that wont give you the functionallity of the backend indeed
| |
| 07:15 | <dem> i was wondering if there was some magical way of doing it
| |
| 07:15 | <ogra> its ot supposed to be run outside a client environment ...
| |
| 07:15 | so no development effor has been put into such a finctionallity
| |
| 07:15 | <dem> right, except when your trying to test your changes
| |
| 07:16 | <ogra> feel free to send me a patch ;)
| |
| 07:16 | (to make that work i mean)
| |
| 07:16 | also note that next iterations will be written in C/GTK
| |
| 07:16 | not in python anymore
| |
| 07:17 | <dem> i'll have some time later on this week, so i'll probably "fix" it up to not really on any hard coded paths, etc so i can test it out of the bzr branch dir
| |
| 07:17 | <ogra> https://launchpad.net/people/ogra/+branch/ltsp/ldm-greeter <- new code for the october release
| |
| 07:17 | <dem> ldm, the greater or both
| |
| 07:17 | <ogra> the greeter for now ...
| |
| 07:17 | <dem> what's the reason for writing it in c?
| |
| 07:18 | <ogra> even though i'd love to switch the actual bianry over as well, but thats something for later releases
| |
| 07:18 | speed
| |
| 07:18 | size
| |
| 07:18 | <dem> does it matter that much?
| |
| 07:18 | <ogra> well, size does
| |
| 07:18 | spees is subjectively biased ...
| |
| 07:19 | <dem> well to be honest, i don't care much for the greeter but rather for the rest of ldm
| |
| 07:19 | <ogra> a relogin with the C code takes 4-5 seconds while one with the python gui takes 8-10
| |
| 07:19 | the python code uses gnomecanvas wich is huge and slow to load
| |
| 07:19 | the C code only uses gtk standard widgets
| |
| 07:19 | <dem> well afaik the olpc guys done a lot of work to speed up gtk/python startup on applications
| |
| 07:20 | <ogra> might be, but C is still the fastest ...
| |
| 07:20 | and smallest
| |
| 07:20 | <dem> i guess i don't see the need
| |
| 07:20 | <ogra> the need is jammcq complaiing about long boots :P
| |
| 07:21 | ltsp 4.2 -> 20secs or so ... ltsp5 rather 90secs
| |
| 07:21 | we want to try to get the 5.x version at least near that
| |
| 07:21 | <jammcq> heh
| |
| 07:22 | hey, I'm only Pre-complaining. the users will do the real complaining
| |
| 07:22 | <ogra> in bootchart speak below 30 secs is my target for gutsy ...
| |
| 07:22 | cliebow has quit IRC | |
| 07:22 | <ogra> (which would be 50 secs or so in jammcq's measuring)
| |
| 07:22 | <jammcq> ogra: is that from kernel startup to LDM ready ?
| |
| 07:22 | missing bios and kernel download?
| |
| 07:23 | <ogra> http://people.ubuntu.com/~ogra/feisty-20070405-1.png
| |
| 07:23 | i want to get this below 30
| |
| 07:24 | <jammcq> well, that needs to be below 30 on the e2300
| |
| 07:24 | <ogra> i.e. sped up the module loading and the ltsp-client config (specifically X here)
| |
| 07:24 | <jammcq> which means it should be much better on the 1220
| |
| 07:24 | J45p3r has joined #ltsp | |
| 07:24 | <ogra> that is a 1220
| |
| 07:24 | <jammcq> yeah, I'm saying we need the e2300 to do sub-30 seconds
| |
| 07:24 | <ogra> well
| |
| 07:24 | <jammcq> well
| |
| 07:24 | <ogra> i dont see that yet
| |
| 07:25 | simply because of the HW the e2300 has ...
| |
| 07:25 | whats that ? 233 or 300Mhz ?
| |
| 07:25 | <jammcq> ltsp-4.2 does it in 41 seconds, power-on to login
| |
| 07:25 | 200mhz
| |
| 07:25 | <ogra> phew
| |
| 07:26 | i know what ltsp 4.2 does ... ;)
| |
| 07:26 | <dem> i guess i'm just not seeing why worry about a micro optimization when there are bigger fish to fry (boot chart)
| |
| 07:26 | <ogra> get some bootchart to work :)
| |
| 07:26 | <jammcq> it's NOT the hardware, it's the SOFTWARE that is the problem
| |
| 07:26 | <ogra> dem, bootchart ?
| |
| 07:26 | <dem> esp for the extra effort
| |
| 07:26 | <jammcq> dem: becuase 4 minutes and 45 seconds is WAY too long for a workstatoin to boot
| |
| 07:26 | <dem> modprobe is like 50% of that chart
| |
| 07:26 | <ogra> yes
| |
| 07:26 | <dem> vs worrying about ldm which is extra 5 seconds (if that)
| |
| 07:27 | <ogra> thats what i said above :)
| |
| 07:27 | <jammcq> dem: considering LTSP-4.2 does the same thing in 41 seconds.
| |
| 07:27 | <ogra> <ogra> i.e. sped up the module loading and the ltsp-client config (specifically X here)
| |
| 07:27 | * jammcq has to shutdown now. mfdutra is coming to pick us up soon | |
| 07:27 | <ogra> jammcq, it doesnt ... it does the same thing in 20 ;) stopmeasuring stuff we cant measure ;)
| |
| 07:28 | <jammcq> ogra: the user doesn't give a rats-ass what's going on during the boot. they know when they hit the power button, and they know when they can log in. That's the ONLY important thing to them. That's the thing that I'm timing
| |
| 07:28 | <ogra> right
| |
| 07:29 | not taking into account that tftp will be totally bound to netwrok speed for example ...
| |
| 07:29 | <jammcq> sometimes people get all caught up in the instrumentation, when the best thing to do is use a simple stop watch
| |
| 07:29 | <ogra> what i want to measure is stuff that doesnt change, which i really can compare in an empiric way...
| |
| 07:30 | <jammcq> ok, what I want to do is make users happy
| |
| 07:30 | <ogra> well, we have bootchart which is the tool we use in our distro to measure bootspeed :)
| |
| 07:30 | right, me too
| |
| 07:30 | <jammcq> surely there's a way we can do that
| |
| 07:30 | <ogra> can you bring a 2300 to seville ?
| |
| 07:30 | <dem> imho there's bigger bang optimizing xorg.conf setup (it does a dkpg-reconfigure on boot)
| |
| 07:30 | <ogra> i'll try to make sure we'll get a monitor
| |
| 07:30 | <jammcq> bootchart is good for analyzing what parts are slow
| |
| 07:30 | but in the end, power-on to login is the important thing
| |
| 07:31 | yes, I'll bring a e2300
| |
| 07:31 | <ogra> dem, there is currently no other proper way to configure X reiably
| |
| 07:31 | <jammcq> I'm hoping to bring 2 of them
| |
| 07:31 | <ogra> good
| |
| 07:31 | even though one will suffice :)
| |
| 07:32 | dem, for feisty we sped it up a bit by queueing the dbconf-comunicate calls into a single one ...
| |
| 07:32 | *debconf
| |
| 07:32 | but beyond that we'll likely have to wait for Xorg to not need a config anymore
| |
| 07:33 | <jammcq> ok, see you kids later
| |
| 07:33 | <ogra> ciao :)
| |
| 07:33 | jammcq has quit IRC | |
| 07:33 | <dem> it be nice to have linux bios on some of these things
| |
| 07:34 | <ogra> heh
| |
| 07:34 | well, not in the focus of ltsp yet ...
| |
| 07:34 | and surely not an area where i want to get my hands dirty :) imagine the trashed BIOS chips if you accidentially introduce bugs :)
| |
| 07:35 | <dem> well i'm thinking more of the boxes jim sells, have them come with linux bios
| |
| 07:35 | cliebow has joined #ltsp | |

| 08:52 | <vanya> ogra, I was reading your conversation about speeding up LTSP 5 and one crazy idea just hit my head :)
| |
| 08:53 | I am using suspend2 to hibernate my machine here, on fat client, this gives me real quick start up time
| |
| 08:53 | can't we use this on thin clients? :)
| |
| 08:54 | but we'll need to transfer large amuount of data in order to wake up our thin clients
| |
| 08:54 | <vagrantc> i think some sort of suspend is/was already supported
| |
| 08:55 | obviously not suspend to disk, but suspend to ram ...
| |
| 08:55 | <vanya> I'm using suspend to disk
| |
| 08:55 | it restores my desktop very quickly
| |
| 08:56 | don't you think that could work for thin clients?
| |
| 08:56 | <vagrantc> so, how would you use suspend to disk without a disk?
| |
| 08:56 | <vanya> we can store images on server
| |
| 08:56 | but the problem will be to transfer those images back to client
| |
| 08:56 | <vagrantc> it would require very low-level support
| |
| 08:56 | right.
| |
| 08:56 | <ogra> yeah, that would need a lot of kernel hacking
| |
| 08:57 | <vanya> what is the maximum size of initrd or how is that thing called? :)
| |
| 08:57 | <ogra> hibernate is as well depending on the bootloader ... so pxelinux hacking goes alongside
| |
| 08:57 | EversonCaratti has joined #ltsp | |
| 08:58 | <ogra> it would be a cool to have thing ... but i dont think thats easily to implement
| |
| 08:58 | Avatara has joined #ltsp | |
| 08:58 | <ogra> i'll keep the hibernate option for fat clients in mind for our default install though, thanks for the suggestion
| |
| 08:58 | jammcq has joined #ltsp | |
| 08:59 | <ogra> (at least wit ubuntu fat clients that should be trivial, if not just work out of the box)
| |
| 08:59 | <vanya> yes, that would be great for fat diskless clients
| |
| 08:59 | <jammcq> ogra: lots of questions here in brazil about fat clients
| |
| 08:59 | <ogra> jammcq, as soon as we have natwork auth ...
| |
| 09:00 | <jammcq> yep
| |
| 09:00 | <ogra> *network
| |
| 09:00 | * jammcq is looking forward to that | |
| 09:00 | <vagrantc> skolelinux/debian-edu already has it
| |
| 09:00 | <jammcq> it'll open up a whole world of possibilities
| |
| 09:00 | <vagrantc> they've had it since the sarge-based debian-edu was released
| |
| 09:00 | <ogra> apart from that sudo chroot /opt/ltsp/i386 apt-get install ubuntu-desktop and fiddle with LDAP yourself ;)
| |
| 09:01 | <vagrantc> might have to tweak which directories get put into ram
| |
| 09:01 | for some applications
| |
| 09:01 | though we should look at unionfs again.
| |
| 09:01 | rgusso-ltsp-br has joined #ltsp | |
| 09:01 | <vagrantc> at least for fat clients
| |
| 09:01 | <ogra> in ubuntu its only gdm so far
| |
| 09:01 | for thin clients as well
| |
| 09:01 | i heard there are workarounds for nfs
| |
| 09:01 | <EversonCaratti> hi, I need 2 paralel printer in a ltsp station. I tryed config lst.conf with PRINTER_0_DEVICE=/dev/lp0 and PRINTER_1_DEVICE=/dev/lp1. then, I go cups and config socket://ws033:9100 (lp0) and 9200 (lp1) but don't print in lp1 !!!!
| |
| 09:02 | <ogra> but i'D prefer to look into something like sshfs ;)
| |
| 09:02 | <vagrantc> debian-live uses unionfs with nfs for network boot fat clients
| |
| 09:02 | <jammcq> EversonCaratti: it's NOT 9200. it should be 9101
| |
| 09:02 | we wouldn't waste 100 port numbers just to get to the next printer :)
| |
| 09:02 | 9100, 9101, 9102, ...
| |
| 09:02 | vagrantc: what does unionfs do for you?
| |
| 09:02 | <EversonCaratti> jammcq, tks!
| |
| 09:03 | rgusso-ltsp-br has quit IRC | |
| 09:03 | <vagrantc> jammcq: no need to have a hard-coded list of which directories to put into ram
| |
| 09:03 | jammcq: i.e. FOO need /var/lib/FOO to be writeable ...
| |
| 09:04 | <ogra> jammcq, it merges directories transparently into one FS
| |
| 09:04 | so we have about 20 tmpfs mounts atm if you type mount on a client
| |
| 09:04 | * McDutchie wonders why anyone would want fat clients. it seems to me like it defeats the purpose of LTSP... | |
| 09:04 | <vagrantc> it probably will result in a little more wasted ram, being the downside
| |
| 09:04 | <ogra> with unionfs you will only see / again
| |
| 09:04 | rgusso-ltsp-br has joined #ltsp | |
| 09:04 | <EversonCaratti> jammcq, I need upload any module TO try it ?
| |
| 09:04 | <vagrantc> ogra: no, we have one tmpfs mount and many bind mounts :P
| |
| 09:04 | <jammcq> EversonCaratti: nope
| |
| 09:05 | <vagrantc> not that it's any less ugly
| |
| 09:05 | <ogra> McDutchie, you can runn 1000 clients on a single server for example ... the load gets put on the client by keeping all advantages a thin client gives you wrt maintenance
| |
| 09:05 | vagrantc, well , indeed :)
| |
| 09:06 | <McDutchie> ogra: but all programs would need to boot over the network, that seems very slow -- wouldn't it be better to just rsync everything to the local hard disk from a master image?
| |
| 09:06 | * vagrantc suspects rsyncing regularly will be more slow than loading things on demand | |
| 09:06 | <jammcq> McDutchie: local hard disk? the whole idea of thin clients is to eliminate moving parts
| |
| 09:06 | <ogra> if all 1000 start OOo simultaneously you will get HD speed issues i guess
| |
| 09:07 | rgusso-ltsp-br has quit IRC | |
| 09:07 | <McDutchie> jammcq: yeah, but i thought we were talking about fat clients now :)
| |
| 09:07 | <ogra> but with rsyncing you will add an additional maintanance level
| |
| 09:07 | <vagrantc> well... if they all load it at once, they'll all be loading the same files and it should be cached in ram
| |
| 09:07 | <jammcq> yes, but who says fat clients require hard disks ?
| |
| 09:07 | <McDutchie> jammcq: i guess that's a point... hadn't considered that
| |
| 09:07 | <jammcq> to me, fat clients just have more ram and faster cpus
| |
| 09:07 | * vagrantc has seen "fat client" used to described disked machines | |
| 09:08 | <jammcq> if you are gonna put a hard disk in it, you might as well load a distro too
| |
| 09:08 | <McDutchie> jammcq: that's what i thought, hence my question - but it makes sense if you eliminate the hard disks.
| |
| 09:08 | <ogra> McDutchie, one big advantage i want to put into the ubuntu ltsp is a "golden workstation", one client that mounts the nfs export raedwrite, so the admin using this WS can influence the whole setup for the company
| |
| 09:08 | <jammcq> there's a grey line that can be moved around, when talking about fat vs thin clients
| |
| 09:08 | <vagrantc> the only case i can see for local hard drive is swap space ... much easier to maintain than a distro.

| 09:09 | <jammcq> via is working on a 2Ghz cpu. take that, and 1gb of ram, and you'd have a dandy thin/fat client with no moving parts
| |
| 09:09 | <ogra> yeah
| |
| 09:10 | <vagrantc> even a 1GHz ain't too shabby
| |
| 09:10 | <jammcq> yeah, and those are available now
| |
| 09:10 | put a hard disk in, and the heat goes up and the power consumption also goes up
| |
| 09:10 | <McDutchie> i guess with 1 GB of RAM, you don't need any swap anyway.
| |
| 09:10 | <jammcq> then, you need a fan, and pretty soon, you haven't saved anything

| |
| 09:11 | <vagrantc> well, if it's a hard disk that is only used for swap, and is able to spin down when un-used ... you might come out ok.
| |
| 09:11 | <ogra> well, depends what you do :P
| |
| 09:11 | (thats my normal used laptop )
| |
| 09:11 | <McDutchie> ogra: true, it does :)
| |
| 09:12 | * jammcq wouldn't want to wait for a hard disk to spin back up when a page fault occurs | |
| 09:12 | <jammcq> clearly there's use cases where a hard disk would be fine
| |
| 09:12 | <ogra> jammcq, pfft youre to imaptient
| |
| 09:12 | <jammcq> :)
| |
| 09:12 | <vagrantc> i've never had a problem with swapping to a drive that needs to spin up first
| |
| 09:13 | nicoAMG has quit IRC | |
| 09:13 | <McDutchie> for non-laptop hard disks it can apparently be bad to spin up and down a lot.
| |
| 09:13 | <vagrantc> most of the time, swap is jus a place to put the junk you never really use. if it's anything more than that, you have a problem.
| |
| 09:14 | * ogra gumbles about weird gnome-screensaver bugs ... | |
| 09:14 | <McDutchie> maybe it would be better to eliminate the junk, and the swap, then.
| |
| 09:14 | <ogra> "my screensaver dies if the filesystem is full"
| |
| 09:14 | <jammcq> ogra: any news on release schedule?
| |
| 09:14 | <ogra> *sigh*
| |
| 09:14 | jammcq, we're testing still
| |
| 09:14 | <vagrantc> typically, my machine boot up, caches about 8 megs to swap, and then stays about the same place for days.
| |
| 09:14 | <ogra> apparently for RC atm
| |
| 09:14 | <jammcq> ogra: so is it unlikely to be released on thursday?
| |
| 09:14 | <ogra> yeah
| |
| 09:15 | <jammcq> bummer
| |
| 09:15 | <ogra> rather a weeklate
| |
| 09:15 | <jammcq> ok
| |
| 09:15 | <ogra> were you planninhg a reease party ?
| |
| 09:15 | *release
| |
| 09:15 | <McDutchie> ('junk' like that is the reason why i run IceWM + ROX on $JOB's LTSP server and not bloatware like GNOME or KDE.)
| |
| 09:16 | * ogra goes fr futther iso testing ... bbl | |
| 09:16 | ogra has quit IRC | |
| 09:16 | <vagrantc> McDutchie: yeah. i tend to run low-resource systems. but that's not always an option for everyone.
| |
| 09:16 | <McDutchie> true
| |
| 09:17 | rgusso-ltsp-br has joined #ltsp | |
| 09:17 | <vagrantc> McDutchie: and even running plain icewm without rox or some other "desktop", i frequently see swap happening.
| |
| 09:17 | <McDutchie> at $JOB people mostly run OO.o though, so no need for extensive desktop environments - OO.o is bloat enough all by itself :)
| |
| 09:17 | rgusso-ltsp-br has left #ltsp | |
| 09:18 | <vagrantc> there are some things that are used once at boot, and rarely ever again, that make sense to swap out to free the ram for more active things.
| |
| 09:18 | <McDutchie> yeah
| |
| 09:20 | but even right now on my laptop (256 MB RAM and I do run KDE) only 2.5 meg of swap is used, so it shouldn't be much under slimmer environments unless you start doing photo/video/sound editing or something.

| 10:13 | <vagrantc> there's no reason you can't use freenx on thin clients.
| |
| 10:13 | or vnc
| |
| 10:13 | you just have to figure out how.
| |
| 10:13 | i most definitely can be done.
| |
| 10:14 | but it depends a lot on exactly what you need and how much tinkering you want to do.

| |
| 11:17 | <ogra> which distro ?
| |
| 11:17 | <str4nd> kubuntu
| |
| 11:18 | (because I think, Gentoo + LTSP isn't good idea ;))
| |
| 11:18 | <ogra> hmm, no idea then, i know in ubuntu/gnome you just use the language selector that installs the matching langpack then ...
| |
| 11:19 | <str4nd> umm, how it works in ubuntu?
| |
| 11:19 | <ogra> i guess kubuntu has a tool for that as well
| |
| 11:20 | you run the language selector, make sure the language-support package you want is installed and thats it ... then you can either select the language in ldm on login or set it in gnome via the gnome settings as you like
| |
| 11:20 | <str4nd> Ok. How I can change ldm to kdm?
| |
| 11:21 | <ogra> i wouldnt do that unless you can live without sound and localdev
| |
| 11:21 | <str4nd> Ouch, ok.
| |
| 11:21 | * ogra is still looking for someone to write a qt gui for ldm | |
| 11:22 | <ogra> i'd appreciate something like that for users like you, but there semms to be only user interestm no developer interest
| |
| 11:25 | <str4nd> :)
| |
| 11:26 | <ogra> if you know any QT programmer who would be interested point him/her to me
| |
| 11:27 | it only needs t run a fullscreen window with input field and print out user, pass, session, language it recieved from the gui settings
| |
| 11:28 | <str4nd> sounds easy
| |
| 11:29 | * vagrantc considers an Xdialog implementation | |

| 12:43 | <kevinl--> hello
| |
| 12:44 | i was told that LTSP developed some kernel module so that linux machines can utilize swap space over TCP/IP
| |
| 12:44 | is that correct?
| |
| 12:44 | <ogra> no
| |
| 12:44 | we use the included nbd module
| |
| 12:45 | <kevinl--> i see
| |
| 12:45 | is there any documentation of the implementation of that as it applies to ltsp ?
| |
| 12:46 | im working on a debian-live based network booting "thick" client environment
| |
| 12:46 | <ogra> the kernel documentation i guess
| |
| 12:46 | <kevinl--> with heavy RAM useable on the clients
| |
| 12:46 | useage*
| |
| 12:46 | too much RAM useage unfortunately
| |
| 12:46 | need to swap, but machines dont have hard drives.
| |
| 12:46 | <ogra> yo surely dont want network swapping if you can avoid it ...
| |
| 12:47 | but beyond that debian uses nbdswapd in ltsp5
| |
| 12:47 | <Guaraldo> Jim just have quit Porto Alegre... he is going home...
| |
| 12:48 | <ogra> note that network swapping will slow down extremely ... we use it in thin clients only to avoid that the client hardlocks ...
| |
| 12:48 | or crashes the X server ...
| |
| 12:49 | kevinl--: check the nbd-server/-client packages in debian ... also the nbdswapd script that ltsp-server installs
| |
| 12:49 | the client side is set up during client boot by the ltsp-client-setup initscript

| 12:55 | a gente pode falar em portugues ou tem que ser em ingles??
| |
| 12:55 | <Guaraldo> na paz...
| |
| 12:55 | que manda, phls...
| |
| 12:56 | <phls> rapaz, eu tinha uma rede com 5 thin clients pendurados em umn servidor P4 2.8
| |
| 12:56 | com 1 gb de ram
| |
| 12:56 | agora troquei o servidor pra um P4 3.8 HT com 2 Gb de ram
| |
| 12:56 | instalei tudo, está funcionando
| |
| 12:56 | mas os clientes estão MUITO lentos
| |
| 12:56 | a parte grafica deles
| |
| 12:57 | usei o ltsp 2.4 com Debian Etch
| |
| 12:57 | antes o servidor tinha Sarge
| |
| 12:57 | <Guaraldo> 4.2...
| |
| 12:57 | <phls> isso
| |
| 12:57 | <Guaraldo> tás usando swap de rede, phls???
| |
| 12:58 | <phls> humm
| |
| 12:58 | acho que sim
| |
| 12:58 | no lts.conf ta definido um swap
| |
| 12:58 | de 64 mb
| |
| 12:58 | <Guaraldo> Pois é... o swap de rede cria muito trafego de rede e deixa bem lento...
| |
| 12:59 | <phls> uma opcao seria tirar?
| |
| 12:59 | <Guaraldo> desativa o swap de rede e teste novamente...
| |
| 12:59 | provavelmente ficará mais rápido...
| |
| 12:59 | Ah!, e recentemente temos o canal ltsp-br
| |
| 13:00 | e é oficial...

| |
| 19:05 | <cliebow> yhan: i think they are very similaar to the ebox 2300..you need to speak to jammcq on it
| |
| 19:05 | are you in USA?

| 19:06 | <yhan> no in Canada

| 19:06 | http://marc.info/?l=ltsp-discuss&m=116666196119861&w=2
| |
| 19:06 | <cliebow> i tr5ied to get some..but the cost and prospect of wiring money to them put me off
| |
| 19:07 | <yhan> that tiny post seems to say that the term boots ltsp in 30 sec
| |
| 19:07 | <cliebow> jammcq and ogra had some boottime problems witht em in ltsp5..like five minutes
| |
| 19:07 | <yhan> do they look to be unclean ?
| |
| 19:07 | arrghh
| |
| 19:07 | <cliebow> but they may have resolved that
| |
| 19:07 | <yhan> I have now some visara 1783 term
| |
| 19:07 | that I got on ebay for a couple of $
| |
| 19:08 | they boot in 9mins
| |
| 19:08 | <cliebow> all mine are junk
| |
| 19:08 | <yhan> it;s a cyrix 233 mhz
| |
| 19:08 | <cliebow> that in ltsp5?
| |
| 19:08 | <yhan> yes with ubuntu edgy
| |
| 19:09 | <cliebow> netvistas are also cyrix board..they boot very fast in ltsp4.2..well 47 seconds
| |
| 19:09 | <yhan> as I have to use the vesa driver for xorg they are too slow
| |
| 19:09 | I wonder if I could find some netvistas at work
| |
| 19:09 | <cliebow> i use the hmmm cant remember.. nsc driver
| |
| 19:09 | i think
| |
| 19:09 | cyrix driver was useless
| |
| 19:09 | <yhan> I tried the cyrix driver
| |
| 19:10 | I got a black screen with the cyrix driver
| |
| 19:10 | <cliebow> jammcq is still ithink in porto alegre..so pretty much out of touch
| |
| 19:11 | <yhan> so nsc driver is compatible with the cyrix 5530 chipset ?
| |
| 19:11 | <cliebow> the diskless works tation 150 is wicked fast..the netvistas video card is just worn out
| |
| 19:11 | i believe so ..on netvista..i may hve something on the netvista posted on the wiki
| |
| 19:12 | dont quote me
| |
| 19:13 | <yhan> search on google for xorg nsc driver
| |
| 19:13 | and check the first result of the search
| |
| 19:13 | <cliebow> the netvista are perfectly usable except for the video card\
