| 05:11 | <vykarian> hi all
| |
| 05:11 | jammcq, there?
| |
| 05:13 | does someone know something about beowulf clustering and LTSP?
| |
| 05:13 | <vagrantc> using LTSP for beowolf clusters?
| |
| 05:13 | <ogra> heh ... nice
| |
| 05:14 | vagrantc, still up ? or already ?
| |
| 05:14 | <vagrantc> ogra: still up, yes. :)
| |
| 05:14 | <ogra> crazy guy :)
| |
| 05:14 | <vagrantc> ogra: someone in india has been using simple-cdd (a debian-cd wrapper) and i've been helping them
| |
| 05:15 | and fxing bugs all along the way
| |
| 05:15 | <ogra> nice
| |
| 05:15 | i'll have to dig into dbein-cd as well soon :(
| |
| 05:15 | <vagrantc> vykarian: you'll have to convince ogra to accept my future patches to split ltsp-client
| |
| 05:15 | <ogra> *debian (indeed)
| |
| 05:16 | <vagrantc> vykarian: otherwise you'll have X running on your beowulf nodes.
| |
| 05:16 | debian-cd is evil.
| |
| 05:16 | there should be a massive campaign to rewrite it.
| |
| 05:16 | <ogra> vagrantc, i still dont understand why you want to split the -client and not the -server since you talk about ltsp-build-client
| |
| 05:16 | <vagrantc> ogra: i want to split both
| |
| 05:16 | <ogra> aha, thats not what you said yesterday
| |
| 05:17 | and thats what confused me
| |
| 05:17 | <vagrantc> ogra: it's maybe not what you saw ... and i didn't clarify it.
| |
| 05:17 | or, didn't clarify well enough ...
| |
| 05:17 | <ogra> ("i want to split ltsp-client to have ltsp-build-client separated")
| |
| 05:17 | <vagrantc> i think that was a typo.
| |
| 05:17 | <ogra> ah
| |
| 05:17 | <vagrantc> one typo leads to days of confusion!
| |
| 05:17 | <ogra> heh
| |
| 05:17 | well, sorted
| |
| 05:18 | <vagrantc> hopefully.
| |
| 05:18 | ogra: so now, with some sleep behind you, and some clarification, what do you think? :)
| |
| 05:18 | <ogra> so whats in -server-core then, only ltsp-build-client and the plugins ?
| |
| 05:19 | i guess the other one would be ltsp-server-services (hmm, bad name) and a meta ltsp-server
| |
| 05:19 | <vagrantc> yeah, probably just ltsp-build-client + plugins ... maybe not all of the plugins (like the stuff that copies the files to the tftp dir)
| |
| 05:19 | if it weren't for the ltsp-client-builder .udeb, i would probably just call it ltsp-build-client
| |
| 05:21 | <ogra> what i'm fearing a bit is that every split will make it more complicated for other distros to grasp muecow
| |
| 05:21 | <vagrantc> and then, i think ltsp-client-core, would just be the barebones what you need to handle read-only NFS root, with hooks for custom scripts ... and then ltsp-client would plug in everything into those hooks.
| |
| 05:21 | gigabytes has joined #ltsp | |
| 05:22 | <ogra> the initial implementation was very easy to understand, the plugins already make it complicated ... now we even split it up and you need to understand debian packaging
| |
| 05:22 | <vagrantc> ogra: well, i think i would be (ostly) satisfied with one more split. and i really think we should consider dropping ltsp-server-standalone ...
| |
| 05:23 | <ogra> how would you do the dhcp config then ?
| |
| 05:23 | i mean you will still need to do the same we do currently
| |
| 05:23 | <vagrantc> recommends on dhcp3-server , install the file the same way ...
| |
| 05:23 | <ogra> you just move oit around to somewhere else
| |
| 05:23 | ltsp-server already has the recommends
| |
| 05:24 | <vagrantc> ah great, even smaller diff :)
| |
| 05:24 | <ogra> -standalone has the dependency that makes sure it really gets installed
| |
| 05:24 | thats the only purpose of -standalone
| |
| 05:24 | <vagrantc> yeah ... and it just doesn't seem like it should warrant a whole package for something that fits the textbook definition of recommends.
| |
| 05:24 | <ogra> well
| |
| 05:24 | its a metapackage
| |
| 05:25 | <vagrantc> we should shove more stuff into it, then.
| |
| 05:25 | more dependencies!
| |
| 05:25 | <ogra> yeah, thats what i wanted
| |
| 05:25 | nah
| |
| 05:25 | but more settings ...
| |
| 05:25 | <vagrantc> well, at any rate ...
| |
| 05:25 | <ogra> i.e. syslog and a syslog config
| |
| 05:26 | (one that sets up default remote logging)
| |
| 05:26 | * vagrantc realized syslog handling is broken by the RC whitelisting stuff | |
| 05:26 | <ogra> not in edgy
| |
| 05:26 | i whitelisted syslog and klog in ubuntu
| |
| 05:27 | <vagrantc> oh. well isn't that simple.
| |
| 05:27 | <ogra> and in edubuntu i even install a syslog setup that logs by default to the server
| |
| 05:27 | wroks properly
| |
| 05:28 | <vagrantc> i still probably have time to fix syslogging in etch...
| |
| 05:29 | <ogra> for the client i think about finally using the not yet existing ubuntu-thin-client package
| |
| 05:29 | <vagrantc> i also might fix the boolean handling :)
| |
| 05:29 | (for the shell scripts)
| |
| 05:29 | <ogra> i know jammcq would like to get the term ltsp out of the face of the users ... that should be a first steop
| |
| 05:30 | <vagrantc> ???
| |
| 05:30 | <ogra> we discussed it in mountainview
| |
| 05:30 | <vagrantc> i don't have any idea what you mean
| |
| 05:30 | <ogra> ltsp is not a term all admins will know, whereas they can imagine something under "thin client"
| |
| 05:30 | <vagrantc> ah!
| |
| 05:31 | <ogra> so jammcq wants to replace ltsp with thin client where possible
| |
| 05:31 | <vagrantc> got it.
| |
| 05:31 | <ogra> i.e. ltsp-manager will be called thin-client-configurator in the future
| |
| 05:31 | so we should think about the naming scheme for the metapackages with that in mind
| |
| 05:32 | <vagrantc> i'm amenable.
| |
| 05:32 | <ogra> the low level packages can still be ltsp-something ...
| |
| 05:32 | <vagrantc> though other thin-client implementations might want that.
| |
| 05:32 | <ogra> which ones ?
| |
| 05:33 | ubuntu doesnt have any others packaged
| |
| 05:33 | who comes first gets served first ;)
| |
| 05:33 | <vagrantc> well, sure.
| |
| 05:33 | it's mostly a "don't grab too generic a name to prevent namespace clash" sort of philosophy ...
| |
| 05:34 | <ogra> sure
| |
| 05:34 | <vagrantc> of course, with ubuntu, you're much more free to select a given application as THE ubuntu choice.
| |
| 05:34 | <ogra> but for me personally its very unlikely that we will get a different thin client solution into ubuntu main
| |
| 05:35 | so the "*ubuntu*-thin-client" package will provide what we support
| |
| 05:35 | <vagrantc> right.
| |
| 05:35 | <ogra> debian is lacking the "no duplication in main" policy here :)
| |
| 05:35 | <vagrantc> exactly.
| |
| 05:36 | <ogra> that keeps me safe in ubuntu :)
| |
| 05:36 | if you still have so much time before etch, you should get jetpipe in to not lack printing
| |
| 05:37 | <vagrantc> i think that's a new feature
| |
| 05:37 | <ogra> well
| |
| 05:37 | its a code replacement
| |
| 05:37 | <vagrantc> code that's been removed from debian for months
| |
| 05:38 | <ogra> but you probably wheer to fast with ripping lp_server out so the RM tream might see it like new
| |
| 05:38 | *were
| |
| 05:38 | <vagrantc> i was called out on copyright issues.
| |
| 05:38 | <ogra> yeah, i know
| |
| 05:39 | well, i think i'll make a separate package for it ... so you can at least backport it ... (which indeed doesnt give you the needed hooks in ltsp)
| |
| 05:39 | <vagrantc> so, rather than getting ltsp removed entirely, i removed the violating code.
| |
| 05:40 | ogra: we can add custom hooks using RC scripts or something ...
| |
| 05:40 | <ogra> (even though its maintenance sillyness to keep 50 lines of code in a separate package)
| |
| 05:40 | <vagrantc> RCFILE_NN
| |
| 05:41 | ogra: yeah, or even 0 lines of code :P
| |
| 05:41 | <ogra> well, 0 lines for a binary from a source that has several k lines is fine imho :)
| |
| 05:41 | <vagrantc> the LTSP in etch will be good enough that we can easily backport missing features.
| |
| 05:41 | or so i think.
| |
| 05:42 | <vykarian> sorry delay, i was afk
| |
| 05:42 | so...
| |
| 05:42 | night in bed..
| |
| 05:42 | i have a beowulf cluster
| |
| 05:42 | and have something like 10-15 LTS clients
| |
| 05:42 | which are celeron 2.53
| |
| 05:42 | running only shell
| |
| 05:43 | <vagrantc> ogra: i was thinking we should move most of the ltspfs-specific code out of ltsp*init/ldm and into scripts in ltspfs ...
| |
| 05:43 | <ogra> heh
| |
| 05:43 | what a waste of CPU
| |
| 05:43 | <vykarian> yeah..
| |
| 05:43 | <ogra> vagrantc, sounds sane
| |
| 05:43 | <vykarian> so.. if I could put that inside the beowulf cluster would be nice ^^
| |
| 05:43 | is there already some effort for that?
| |
| 05:43 | <ogra> is there a 2.6 variant of beowulf already ?
| |
| 05:44 | <vykarian> yeap
| |
| 05:44 | 1 min
| |
| 05:45 | <ogra> i'm doing ubuntu, so i'm bound to the ubuntu kernel which only accepts patches that will (or is likely to) go in the upstream branch on kernel.org ... so i'm likely the wrong person to ask, but theoretically it should be possible to use beowulf with ltsp
| |
| 05:45 | <vagrantc> ogra: did i tell you i split the init scripts into plugins ?
| |
| 05:45 | ogra: as a post-etch possibility ...
| |
| 05:46 | <ogra> got a branch of that ?
| |
| 05:46 | <vagrantc> ogra: yes.
| |
| 05:46 | <ogra> i'll take a look for feisty :)
| |
| 05:46 | so you get it tested before etch ;)
| |
| 05:46 | <vagrantc> ogra: http://llama.freegeek.org/~vagrant/bzr/ltsp/features/vagrant-ltsp-initscripts
| |
| 05:46 | ogra: :P
| |
| 05:48 | ogra: that branch includes most of the debian changes that you haven't merged yet, though.
| |
| 05:48 | gigabytes has quit IRC | |
| 05:49 | <ogra> i merged over 100 revisions three or four weeks ago
| |
| 05:49 | there shouldnt be much i'm missing
| |
| 05:49 | <vagrantc> ogra: there's some things...
| |
| 05:50 | ogra: i sent you an email about a few relatively minor patches for mainline
| |
| 05:50 | <ogra> yep
| |
| 05:50 | they are trivial
| |
| 05:50 | did you merge gadis screen_scripts branch ?
| |
| 05:51 | the one he did in detroit ?
| |
| 05:51 | <vagrantc> speaking of trivial: http://llama.freegeek.org/~vagrant/bzr/ltsp/features/vagrant-ltsp-boolean/
| |
| 05:51 | it's so simple.
| |
| 05:51 | ogra: i merged some of gadi's stuff, but not much.
| |
| 05:52 | <ogra> why ? was it to bad ? :P
| |
| 05:52 | <vagrantc> i hink i was just focused on other things ...
| |
| 05:53 | <ogra> ok ... i will look through them as well
| |
| 05:54 | MoL0ToV has quit IRC | |
| 05:56 | <ogra> ok, merged and pushed the -mainline changes
| |
| 05:56 | <vagrantc> excellent.
| |
| 05:56 | <ogra> it will take a moment for LP to sync it ...
| |
| 05:56 | <vagrantc> ogra: may as well merge the boolean changes
| |
| 05:56 | <ogra> i really need to move that branch to LP
| |
| 05:57 | yep thats the next one
| |
| 05:57 | <vagrantc> he initscripts changes will result in a lot of conflicts ...
| |
| 05:57 | <ogra> well
| |
| 05:58 | <vagrantc> i've done some test merges ... the changes are big, but there's a lot of conflicts, some of which are difficult to merge.
| |
| 05:58 | <ogra> i'm careful about the init stuff anyway ... i'd like to have it as upstart compliant as possible from the beginning
| |
| 05:58 | <vagrantc> i basically just implemented the plugins system for ltsp-client
| |
| 05:58 | both init scripts ...
| |
| 05:58 | it was really easy.
| |
| 05:59 | i did something a little different from the ltsp-server stuff, though ... instead of installing all the vendors, i just install the plugins specific to that vendor ...
| |
| 05:59 | i.e. it only includes the Debian plugins
| |
| 06:00 | that way, we don't have to run lsb-release twice for each boot, which actually takes a couple seconds even on some moderately fast thin-client hardware.
| |
| 06:00 | <ogra> younds good
| |
| 06:01 | but still i have to look into upstart for feisty and make the ubuntu side work with it
| |
| 06:01 | <vagrantc> i was even thinking we might want to move ltsp-server in that direction, just to keep the binary packages slightly smaller.
| |
| 06:01 | <ogra> it will give us instant booting at some point ;)
| |
| 06:01 | <vagrantc> sometimes, things like upstart make me feel so.... linear.
| |
| 06:04 | <ogra> heh
| |
| 06:04 | seems a lot of debian guys are helping with upstart already, so it might be in etch+1
| |
| 06:05 | whats etch+1 called btw ?
| |
| 06:05 | <vagrantc> in many ways, though, i look forward to it. it seems petty slick, and possibly much easier to implement some things.
| |
| 06:05 | lenny
| |
| 06:07 | looks like upstart in debian/experimental is even current with ubuntu/feisty
| |
| 06:11 | <ogra> yeah
| |
| 06:11 | die sysvinit
| |
| 06:12 | <vagrantc> heh
| |
| 06:12 | we should just implement ltsp-build-client as upstart hooks or something.
| |
| 06:12 | <ogra> haha
| |
| 06:13 | i think that would slow donw booting a tad
| |
| 06:15 | <vagrantc> ogra: are you planning on getting locales working for feisty? it would probably reduce the ubuntu diff a lot.
| |
| 06:16 | <ogra> well, i was planning to, yes, but that wont reduce the diff i fear
| |
| 06:16 | for me its just apt-get install language-pack-base-$LANG
| |
| 06:17 | <vagrantc> well, you won't have to fork all your LC_ALL=C hacks anymore, though.
| |
| 06:17 | <ogra> that sets everything correctly
| |
| 06:17 | right
| |
| 06:17 | <vagrantc> so that will decrease the diff :P
| |
| 06:17 | <ogra> but i'll require the language pack
| |
| 06:17 | which in turn forces me to set the keymap etc ....
| |
| 06:18 | and indeed forces translations for ldm ...
| |
| 06:18 | <vagrantc> heh.
| |
| 06:19 | ogra: are you planning on splitting ldm into it's own source package for feisty?
| |
| 06:20 | <ogra> i wasnt, but shouldnt be a prob to do so ...
| |
| 06:21 | <vagrantc> i think it would make backporting easier.
| |
| 06:21 | gigabytes has joined #ltsp | |
| 06:21 | <ogra> even though i dont see a reason why we should have anouther source ... we'll drown in branches
| |
| 06:21 | <vagrantc> ldm is the primary reason it became difficult to backport to sarge.
| |
| 06:22 | <ogra> right, but more sources make our life a lot harder
| |
| 06:22 | <vagrantc> though the newer python policy should make that less of a problem...
| |
| 06:22 | <ogra> i'm not sure a backport justifies the extra work
| |
| 06:22 | especially since you'll soon have a stable release to point users to
| |
| 06:22 | <vagrantc> i'm not as set on the split as i once was...
| |
| 06:23 | well, the ldm split. i'm still set on the ltsp-server/ltsp-client split.
| |
| 06:24 | <ogra> on a binary base thats totally fine with me ... on a source base we'll have to discuss each bit ... i really dont want to get into maintenance hell
| |
| 06:24 | <vagrantc> sure.
| |
| 06:25 | i mean, i was kind of hoping to move this project to a totally unmaintainable state, but i realize not everyone shares that goal.
| |
| 06:25 | <ogra> haha
| |
| 06:27 | what about the switch to pulse, can you do that in debian easily ?
| |
| 06:27 | <vagrantc> it looks like all the packages are there.
| |
| 06:27 | in etch, even.
| |
| 06:27 | so it probably wouldn't make backporting to etch hard
| |
| 06:28 | <ogra> cool
| |
| 06:28 | i hope to get that done this week or the weekend
| |
| 06:29 | so i can finally control the volume on my music thinc client ;)

| 11:53 | <pscheie> Gadi: !!!!!!!!!
| |
| 11:53 | Your X_HORZSYNC = "30-80" suggestion to get 1600x1200 display worked like a champ!
| |
| 11:58 | <Gadi> nice. which proves the theory that im full of it :)
| |
| 11:58 | whatever it is
| |
| 11:59 | <pscheie> More precisely, I had to set it to X_HORZSYNC = "30-90" to get 16x12
| |
| 11:59 | X_HORZSYNC = "30-80" only got me to 1280x1024
| |
| 11:59 | but even that was an improvement
| |
| 11:59 | oddly, setting it to 90 always gives me 16x12 no matter what res I specify
| |
| 12:00 | what exactly is X_HORZSYNC specifying?

| 12:03 | primeministerp has quit IRC | |
| 12:07 | <Gadi> horizontal sync frequency of the video card (to match that of the monitor it is plugged into)
| |
| 12:07 | you need higher frequencies to get higher resolutions
| |
| 12:07 | cascade has quit IRC | |
| 12:08 | <Gadi> but, old CRT monitors will break if you specify too high a frequency
| |
| 12:08 | so the defaults are kept low
| |
| 12:08 | <pscheie> If I understand things correctly, when I switch to the client machine's local install of FC6, which gives me 16x12,
| |
| 12:09 | the monitor reports its scan rate as 59hz
| |
| 12:09 | or so it says
| |
| 12:09 | <Gadi> most distros use a utility to probe the monitor to ask it what frequencies and such it supports
| |
| 12:10 | LTSP does not
| |
| 12:10 | so, it uses a Xorg default (31-59)kHz
| |
| 12:10 | but, for many monitors, you need a higher frequency range to get higher resolutions
| |
| 12:12 | <pscheie> I seem to recall from the manual for the monitor that it will handle frequencies up to around 150
| |
| 12:12 | speculating wildly here, would there be an advantage if ltsp had such a probing tool?
| |
| 12:12 | putting aside how much work it would take to develop such a thing
| |
| 12:13 | <jammcq> LTSP-5 does, in Ubuntu (I'm assuming that Ubuntu already has that)
| |
| 12:13 | <pscheie> ah, good things come to those who wait ;-)
| |
| 12:14 | what about multiple resolutions? that is, setting X_MODE_1 and X_MODE_2 never work for me
| |
| 12:14 | or rather, pressing Ctl-Alt-+ never does anything for me

| 12:20 | <jammcq> pscheie: how about on a normal Linux box, does Ctrl-Alt-+ work there?
| |
| 12:21 | <pscheie> yes--well, it has in the past; I haven't tried it on this FC6 install yet
| |
| 12:22 | <Gadi> !seen ogra
| |
| 12:22 | <ltspbot> Gadi: ogra was last seen in #ltsp 5 hours, 52 minutes, and 41 seconds ago: <ogra> so i can finally control the volume on my music thinc client ;)
| |
| 12:24 | <Gadi> anybody here using Ubuntu's LTSP (via ldm)?
| |
| 12:24 | don't everybody jump at once
| |
| 12:26 | <pscheie> jammcq: I recall a few years ago getting the multiple X_MODEs working under LTSP but the lower resolutions ran the desktop off the screen
| |
| 12:26 | <jammcq> yes
| |
| 12:26 | <pscheie> isn't there a command, something like xdandd or some such that fixes that, at least in a fat client?
| |
| 12:26 | <jammcq> the lower resolutions give you a "view port" of the larger screen
| |
| 12:26 | but that's NOT ltsp that does that
| |
| 12:26 | that's just the way it works in X
| |
| 12:27 | <Gadi> pscheie: ur thinking of xrandr
| |
| 12:27 | mistik1 has joined #ltsp | |
| 12:27 | <pscheie> Gadi: righto!
| |
| 12:27 | does that work on a tc?
| |
| 12:27 | <Gadi> sure
| |
| 12:29 | <pscheie> anyone have any ideas why setting X_MODE_1 & x_MODE_2 wouldn't work?
| |
| 12:29 | <jammcq> I think you need 0 too
| |
| 12:29 | <pscheie> yeah, I've already got that; that's the only res I get
| |
| 12:30 | <jammcq> well, you'd have to make sure that all of the resolutions are supported by the hardware. the xserver will throw away invalid modes
| |
| 12:30 | then, once they are all valid, then it should just work
| |
| 12:30 | if it doesn't, you could get to a shell on the client, and look at the Xorg logfile, and see if it retained those modes you asked for
| |
| 12:30 | <Gadi> pscheie: even if you only specify X_MODE_0, you should be able to change res to any lower resolution in Gnome > Screen Resolution
| |
| 12:31 | (your login screen will always be at the highest resolution)
| |
| 12:31 | <pscheie> the odd thing is if I set the upper end of X_HORZSYNC to 80 I get 1280x1024
| |
| 12:31 | <Gadi> thats not odd
| |
| 12:32 | <pscheie> if I set it to 90 I get 16x12 without changing the X_MODE_0 res
| |
| 12:32 | <Gadi> evidently, to get 1600x1400, you need a horizontal sync greater than 80kHz
| |
| 12:32 | <pscheie> yes, but setting to higher forces 16x12?
| |
| 12:32 | <jammcq> there's an interesting document from eric raymond describing the modelines and the frequencies.
| |
| 12:32 | <Gadi> you mean even with X_MODE_0 specified?
| |
| 12:33 | <pscheie> yes
| |
| 12:33 | <jammcq> pscheie: could we see your lts.conf file?
| |
| 12:33 | <Gadi> are you specifying it in the [Default] section of lts.conf or a specified section?
| |
| 12:33 | <pscheie> jammcq: do you have a link to eric's doc?
| |
| 12:33 | <jammcq> I can find it
| |
| 12:33 | <Gadi> if specified, check the hostname on the client
| |
| 12:33 | your client may not be getting the setting
| |
| 12:34 | because it may not know its hostname

| 15:11 | <g333k_work> hi, where can I get ltsp 5 from? to install in xubuntu
| |
| 15:16 | <jammcq> g333k_work: you should be able to apt-get it
| |
| 15:16 | is it Dapper or Edgy xubuntu?
| |
| 15:17 | <g333k_work> jammcq, yep xubuntu edgy
| |
| 15:17 | jammcq, what pkgs do I need to install?
| |
| 15:19 | <moquist> ogra (anybody): what's the recommended way to get ltspfs in edubuntu (edgy)? last time I had a question like that I just started installing packages, and ya'll said "NOnononono", so this time I'm asking first. :)
| |
| 15:20 | <jammcq> g333k_work: I think it's just "apt-get install ltsp-standalone-server"
| |
| 15:20 | <g333k_work> jammcq, ltsp-server-standalone :p
| |
| 15:20 | <jammcq> yeah, that one :)
| |
| 15:20 | <moquist> jammcq: any comment on ltspfs in ubuntu?
| |
| 15:20 | <jammcq> hey O'Quist
| |
| 15:20 | mistik1 has quit IRC | |
| 15:21 | <moquist> ...if it's supposed to "just work", it isn't. :(
| |
| 15:21 | jammcq: hey hey hey
| |
| 15:21 | <jammcq> umm, i'm not sure what package you need
| |
| 15:21 | <moquist> np
| |
| 15:21 | <g333k_work> jammcq, it a very cool idea to integrate ltsp to distros.... I remember installinf ltsp with ltspadmin...
| |
| 15:22 | jammcq, now that I installed it what? should I have to run ltspadmin again?
| |
| 15:22 | <moquist> hrm. it kinda looks like the packages are already installed so that it should "just work".
| |
| 15:23 | g333k_work: you need to run ltsp-build-client IIRC
| |
| 15:23 | g333k_work: IIRC that's what creates /opt/ltsp/i386
| |
| 15:23 | <jammcq> 'ltspadmin' is ONLY for ltsp-4.x
| |
| 15:23 | <g333k_work> moquist, ok
| |
| 15:23 | <jammcq> you would NEVER use it for LTSP-5
| |
| 15:24 | <g333k_work> jammcq, ok... I'm just migrating to 5, so I'm pretty new again
| |
| 15:24 | <jammcq> unless we modify it for use in ltsp-5, but currently, that's not what we are planning to do
| |
| 15:26 | mistik1 has joined #ltsp | |
| 15:27 | <g333k_work> is there a manual to install ltsp 5 in ubuntu edgy¡
| |
| 15:27 | ?
| |
| 15:28 | <moquist> g333k_work: not that I know of; the recommendation is to use the edubuntu install CD.
| |
| 15:28 | <g333k_work> moquist, :o
| |
| 15:28 | <moquist> g333k_work: you could easily use the edubuntu install CD and then apt-get install xubuntu-desktop.
| |
| 15:28 | that would be *WAY* easier than what you're doing. :)
| |
| 15:28 | <jammcq> https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
| |
| 15:29 | <g333k_work> moquist, well I'm going in the other direction... installing xubuntu first then geting ltsp
| |
| 15:29 | <moquist> g333k_work: right. I was recommending that you change direction. :)
| |
| 15:30 | <g333k_work> jammcq, nice!

| 15:36 | <g333k_work> vagrantc, ltsp-server-standalone :p
| |
| 15:36 | <vagrantc> moquist: i think it's simply installing ltspfs on the ubuntu server and ltspfsd into the ltsp chroot, and setting LOCALDEV=True in the chroot's /etc/lts.conf
| |
| 15:36 | g333k_work: sure, if you need the dhcp server, too.

| |
| 16:11 | <jammcq> try running top and see what it's doing

| 16:15 | <g333k_work> jammcq, I will add 512mb of RAM more
| |
| 16:15 | <vagrantc> g333k_work: possibly a bad hard disk, then.
| |
| 16:16 | i guess it could be running out of ram and falling into perpetual swapping
| |
| 16:16 | <g333k_work> vagrantc, jammcq, thats why I need popup messges... to tell my clients that the server is going to be down for a minutes
| |
| 16:17 | vagrantc, how to solve it?
| |
| 16:17 | <jammcq> take the server down. they'll get the hint pretty quickly
| |
| 16:18 | <vagrantc> if the clients are froze, it won't be any surprise if they break further
| |
| 16:20 | <jammcq> is it totally impossible to run anything? or does it just take alot longer for programs to come up?
| |
| 16:20 | and... how many clients do you have, and how much ram now?

| |
| 16:22 | <g333k_work> jammcq, I had 1G of RAM.... and I have about 25 clients now
| |
| 16:22 | jammcq, all of them just using firefox
| |
| 16:22 | <jammcq> that's not enough
| |
| 16:22 | <g333k_work> jammcq, now I have 1,5G
| |
| 16:23 | <jammcq> that's still pretty tight
| |
| 16:23 | <g333k_work> jammcq, is not enough ??
| |
| 16:23 | <jammcq> do you know how to see if you are swapping?
| |
| 16:23 | <g333k_work> jammcq, how can I calculate how much RAM do I need for each client that I add?
| |
| 16:23 | jammcq, yep with the 'free' command

| |
| 16:24 | <g333k_work> jammcq, but I just turned it on.... lets wait some hours
| |
| 16:24 | <jammcq> i'm surprised it doesn't just crash
| |
| 16:25 | <vagrantc> looks like there's plent of free ram ...
| |
| 16:25 | g333k_work: it doesn't looke like your swap is on, though. there is "0" in the total swap.
| |
| 16:33 | <g333k_work> vagrantc, yep I realized that
| |
| 16:33 | I'm trying to turn it on but I cant
| |
| 16:35 | <vagrantc> mkswap /dev/SWAP_DEVICE && swapon /dev/SWAP_DEVICE
| |
| 16:35 | or maybe ubuntu has some crazy GUI swap manager... :)
| |
| 16:36 | <mistik1> heh
| |
| 16:38 | <g333k_work> how much swap do I need? if I have 1.5G of ram?

| 16:41 | <vagrantc> g333k_work: you'll hear everything from 1-3 times the ram.
| |
| 16:43 | g333k_work: so, anywhere between 1.5-4.5 GB of swap. though i tend to thing 4.5 GB of swap ... well... if you're using anywhere near that much swap, you probably just need more ram.
| |
| 16:43 | but i also haven't worked with servers that host more than 10-20 users at once.
