| 03:18 | on clients, by ltsp-localapps I can rung glxgerars and glxinfo too
| |

| |
| 03:18 | what I have wron?
| |
| 03:18 | *wrong
| |
| 03:23 | Alimar has joined #ltsp | |
| 03:24 | <Alimar> what's the best raid (software) setup for ltsp?
| |
| 03:24 | Good day!
| |
| 03:25 | RiXtEr has quit IRC | |
| 03:25 | <HrdwrBoB> raid10 .. probably
| |

| 03:33 | dlezcano has joined #ltsp | |
| 03:36 | <Alimar> how do you maintain them?
| |
| 03:36 | or does it maintain itself
| |
| 03:37 | can I use 2 hdd for this then add another 2 later -- w/o much hassle?

| 03:54 | <Alimar> anybody know how I can troubleshoot a client that blanks after a logout? Using Ubuntu LTSP -- I'm guessing it's the ldm or the XSERVER=vesa that is causing this but I have no way of telling...
| |
| 03:55 | because I have to wait -10-30min for it to boot/power up normally -- but will blank again every logout
| |
| 03:55 | That is Ubuntu 10.10 LTSP
| |
| 04:04 | <Komunista> the clients VGA is CLE266
| |
| 04:06 | <HrdwrBoB> Alimar: not.. really
| |
| 04:06 | Alimar: you need to read about raid
| |
| 04:07 | alkisg has joined #ltsp | |
| 04:10 | <Alimar> Komunista: how is that? xchange vesa for CLE266?

| 04:14 | zz_evil_root has joined #ltsp | |
| 04:14 | zz_evil_root is now known as evil_root | |
| 04:16 | <Alimar> I was also thinking that since LDM is restarted every logout -- it may not read the lts.conf when it is restarted during log out...
| |
| 04:24 | <Komunista> Alimar: VIA Technologies, Inc. VT8623 [Apollo CLE266] integrated CastleRock graphics (rev 03)
| |
| 04:28 | <Alimar> I think is is S3 Inc. VT8375 [ProSavage8 KM266/KL266] -- the on board video

| 05:10 | <simbulu> Playing around with ltsp - mostly on centos 5.5 64 bit with and without xen - but not really getting to the point where production can begin. I wonder where the real source for LTSP is hidden ...
| |
| 05:12 | as I am getting boored with all this OS integration - and really just want to install my favorite OS and then add ltsp from source.
| |
| 05:28 | <Komunista> Alimar: I have no more info, than lspci give to me
| |
| 05:33 | alkisg has joined #ltsp | |
| 05:36 | <simbulu> Where is source for lstp available ?
| |
| 05:39 | <alkisg> !source
| |
| 05:39 | <ltspbot> alkisg: My source is at http://supybot.com/
| |
| 05:39 | <alkisg> !ltsp-source
| |
| 05:39 | <ltspbot> alkisg: "ltsp-source" :: at http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/files

| 08:41 | <robehend1> say, I'm getting some random lock-ups with firefox lately. I'm running fatclients, with a mix of Pent4, celeron D, and Celeron machines, all with 512 mb of ram. I'm getting the classic "greyed out, not responding" firefox screen, which then must be force quit
| |
| 08:41 | i have NBD_SWAP = True int he lts.conf
| |
| 08:42 | <mgariepy> robehend1, if you wait does it comes back ?
| |
| 08:42 | <robehend1> in my knowledge, yes. I'm getting these reports from students, however, whose answer to locking up programs is "click it alot of times"
| |
| 08:42 | <evil_root> can you try NBD_SWAP = false if these are fat clients let them use the clients ram
| |
| 08:43 | <robehend1> we just recently added the NBD_Swap, hoping to stop the freezing. it happened before as well
| |
| 08:43 | <mgariepy> is the load higher then usual on your applications server or the home server?
| |
| 08:43 | <robehend1> single server
| |
| 08:43 | <evil_root> how many clients active at one time?
| |
| 08:43 | <robehend1> on this server, only 18
| |
| 08:43 | all fat clients. server is a 2x quad core xeon with 32 gigs of ram
| |
| 08:44 | <mgariepy> robehend1, i saw this on thin client with localapps when the i/o wait on the $HOME server was quite high.
| |
| 08:44 | <evil_root> oh
| |
| 08:44 | how many hard drives on the server
| |
| 08:44 | <robehend1> evil_root: 2, set in raid 0, i believe
| |
| 08:44 | <evil_root> iostat -x 1
| |
| 08:44 | on the server
| |
| 08:44 | see if the utilization of the drive stays high
| |
| 08:45 | if so you need more hard drives
| |
| 08:45 | <robehend1> hmm, that gave me tons of data, let me dig a minute
| |
| 08:45 | <evil_root> :D
| |
| 08:45 | data is always good
| |
| 08:46 | <robehend1> what am i looking for, anyways/
| |
| 08:46 | <evil_root> but yea your bottle necking somewhere
| |
| 08:46 | what os?
| |
| 08:46 | <robehend1> ubuntu 10.04
| |
| 08:46 | <evil_root> drive sdc or sda?
| |
| 08:46 | or what ever its called
| |
| 08:46 | ok you should see something like...
| |
| 08:47 | Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util
| |
| 08:47 | scd0 0.00 0.00 0.00 0.00 0.00 0.00 8.61 0.00 2.12 2.12 0.00
| |
| 08:47 | your hard drive is going to be probably sda
| |
| 08:47 | <robehend1> ah, i see what happened. my ssh screen was to small, caused line wrap, ruined the formatting.
| |
| 08:47 | <evil_root> lol
| |
| 08:47 | <robehend1> Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util
| |
| 08:47 | sda 0.04 7.14 0.36 4.49 13.85 93.05 22.02 0.63 129.68 1.53 0.74
| |
| 08:48 | ya, those look like the bottle neck
| |
| 08:48 | <evil_root> ok watch it constantly threw the day, and see if the util stays high
| |
| 08:48 | <robehend1> what's considered high? above 10/
| |
| 08:49 | <evil_root> the util is percentage so if its constantly above 50% i would say thats high
| |
| 08:49 | it should refresh every second for ya
| |
| 08:49 | <robehend1> but, if i'm not mistaken, the util was only .74%
| |
| 08:49 | <evil_root> for that split second the command ran
| |
| 08:49 | run it all day
| |
| 08:50 | <robehend1> ah, ok
| |
| 08:50 | <evil_root> and when firefox starts locking up, i bet it will be high
| |
| 08:50 | <robehend1> hmm, i might want to go..force it to look up..
| |
| 08:50 | er, lock
| |
| 08:50 | <evil_root> no to proper test you need the users putting a load on it
| |
| 08:50 | we dont need a cpu or ram load, we need read/writes
| |
| 08:50 | <markit> robehend1: have you also increaded the swap space? SIZE=512 in /etc/ltsp/nbdswapd.conf (new file)
| |
| 08:50 | <evil_root> and firefox does a crap load
| |
| 08:51 | <robehend1> oh, yes, of course. by force i meant go log into the machines and open up firefox and some flash games
| |
| 08:51 | <markit> (I've not read the all thread,just had a look, apologise if I'm saying nothing relevant or already tried)
| |
| 08:51 | <robehend1> evil_root: is Chromium better? i've been testing it as a replacement
| |
| 08:51 | <evil_root> not even flash games, open like 40 tabs
| |
| 08:51 | <robehend1> brb
| |
| 08:52 | <evil_root> chrome and firefox have their benefits each
| |
| 08:52 | i let my users choose between the two
| |
| 08:52 | <markit> what about ff4 beta?
| |
| 08:52 | NeonLicht has quit IRC | |
| 08:52 | <evil_root> yet to try it
| |
| 08:52 | <markit> maybe should solve the memory usage madness
| |
| 08:53 | <evil_root> i got a gentoo mentality, i am behind releases by one or two years lol
| |
| 08:53 | if it does that will be awesome
| |
| 08:53 | * dberkholz is running ff4 beta on gentoo... | |
| 08:53 | <evil_root> is it masked?
| |
| 08:54 | or ~x6
| |
| 08:54 | ~x86*
| |
| 08:54 | <robehend1> ack back
| |
| 08:54 | <dberkholz> it's in the mozilla overlay, i think. don't know how it's keyworded/masked. i just use eix to find it and autounmask/emerge --autounmask to use it.
| |
| 08:54 | <markit> evil_root: do you use ACL by chance? to create a shared dir...
| |
| 08:54 | <robehend1> firefly9
| |
| 08:54 | gah. must learn alt tab
| |
| 08:54 | <evil_root> acl? access control list?
| |
| 08:54 | <markit> I've troubles with acl and file copied from teacher's home
| |
| 08:54 | evil_root: exactly, for the file system
| |
| 08:55 | (not squid :))
| |
| 08:55 | <evil_root> no i cant say i have sorry
| |
| 08:55 | <robehend1> markit: yes, the SIZE=512 is set in nbdswap.conf

| 09:00 | NeonLicht has joined #ltsp | |
| 09:13 | <robehend1> evil_root: looks like you were right. i just had a set of 96%, then 78%, then back down to 3%..
| |
| 09:13 | <evil_root> yea i was having that issue a while ago
| |
| 09:13 | switched to cluster
| |
| 09:15 | <markit> mm my school setup is also with firefox 3.x... I'm scared (we are at the first days of usage this week)
| |
| 09:16 | robehend1: have you tested FF 4 beta?
| |
| 09:16 | btw, I've not installed flash in the server... will eat all bandwidth, and CPU
| |
| 09:17 | <evil_root> god dam youtube!!!
| |
| 09:19 | <markit> evil_root: hope WebM will be better and all videos will be converted soon
| |
| 09:20 | <evil_root> agreed
| |
| 09:20 | and html5 is the shit
| |
| 09:21 | <elias_a> ...one should use :)
| |
| 09:22 | But why not run FF and Flash player as local app?
| |
| 09:22 | gnunux has quit IRC | |
| 09:22 | <elias_a> Just wondering...
| |
| 09:22 | <evil_root> if your clients can handle it elias_a's idea is a logical one
| |
| 09:23 | <elias_a> evil_root: What sort of hw are you running?
| |
| 09:23 | That is unable to do it....
| |
| 09:24 | <evil_root> well i have flat clients with quad cores and sli video cards, and i have thin clients that go all the way down to a 750Mhz processor with 256M ram
| |
| 09:24 | and everything inbetween
| |
| 09:24 | i love linux
| |
| 09:24 | or did you mean what server hard ware i got?
| |
| 09:25 | <NeonLicht> Your thin clients are more powerful than my fat clients :)
| |
| 09:26 | <evil_root> lol
| |
| 09:26 | we have almost every model from disklessworkstations.org
| |
| 09:26 | <NeonLicht> Cool! We only have old PCs.

| 09:29 | <elias_a> evil_root: OK. If there's not enough CPU power, there is not...
| |
| 09:30 | <evil_root> on the clients that are too old ff-flash run server side, on clients that can its run locally
| |
| 09:31 | gnunux has quit IRC | |
| 09:31 | <evil_root> but where we shine is our server farm
| |
| 09:31 | <robehend1> markit: no, i have not.
| |
| 09:31 | gnunux has joined #ltsp | |
| 09:32 | <evil_root> we are working with the public schools here to centralize all the districts, so we have students that can log into a public school computer anywhere in the state
| |
| 09:32 | <robehend1> evil_root: where is that, can i ask/
| |
| 09:32 | <evil_root> montana
| |
| 09:32 | <robehend1> evil_root: based on tlsp?
| |
| 09:32 | er, ltsp*
| |
| 09:32 | <evil_root> ltsp yep
| |
| 09:32 | fuck active directory
| |
| 09:33 | <robehend1> do you have any press releases or documentation? I'm always needing examples of other places doing this, so my school board doesnt go 'but its not windowsssss!!!"\
| |
| 09:33 | <evil_root> no this is not offical yet
| |
| 09:33 | <robehend1> ah, ok. thats what i figured, else it'd be all over the news
| |
| 09:33 | <evil_root> but we have dumped like 2 million into it
| |
| 09:34 | <robehend1> wow. my total allocation so far is 400 dollars, for the ram upgrade to the server
| |
| 09:34 | <markit> disklessworkstations.org has HP thin with... Windows embedded, sigh!!!

| 09:34 | shawnp0wers has joined #ltsp | |
| 09:34 | <evil_root> thats one of our cluster points
| |
| 09:34 | <robehend1> so are you like, setting up a big old server farm, then replicating those servers to a local site for the schools?
| |
| 09:35 | or just having distributed cluster points hooked up through strong wan links
| |
| 09:35 | <evil_root> we have 4 of those exact setups over the state
| |
| 09:35 | <robehend1> hey, i've got some of those poweredge machines
| |
| 09:35 | <evil_root> my company owns 95% of the fiber in montana
| |
| 09:35 | <NeonLicht> What state is it?
| |
| 09:35 | <robehend1> well that definately helps
| |
| 09:35 | <evil_root> montana
| |
| 09:35 | <robehend1> we're still on an ethernet hyperextender..
| |
| 09:36 | <evil_root> ouch man that sucks
| |
| 09:36 | i have gig from my desk to a town that is 4 hour drive away
| |
| 09:36 | <robehend1> ya. so i'm putting servers at each sites
| |
| 09:36 | oh, nice.
| |
| 09:37 | what does montana use for standardized testing? Pearson Testnav?
| |
| 09:37 | <evil_root> here is like a 10 year old fiber map
| |
| 09:40 | standardized testing?
| |
| 09:40 | <robehend1> ya, for no child left behind
| |
| 09:40 | thats my biggest hurdle right now to a full linux deployment. mn uses pearson testnav 6.9, which runs only on windows/mac
| |
| 09:40 | <evil_root> idk, that started after i was already done with highschool
| |
| 09:41 | <robehend1> ..even though its just java and flash...
| |
| 09:41 | <evil_root> put wine on for when your really need windows
| |
| 09:41 | <robehend1> tried that. wont work
| |
| 09:41 | it runs its own, self contained versions of java and flash, and when i run it in wine, it can't find em for some reason
| |
| 09:41 | <evil_root> then have like screen_8 be remote desktop
| |
| 09:41 | <robehend1> thats what i'm thinking, trying to avoid if possible, but thinking
| |
| 09:42 | <evil_root> yea thats not a real full linux deployment
| |
| 09:42 | <robehend1> trying to keep licensing costs low, and get rid of windows if possible
| |
| 09:43 | <markit> robehend1: in your experience, the ethical reasons of Free software don't count for schools?
| |
| 09:44 | <evil_root> ethical reasons?
| |
| 09:44 | <markit> evil_root: yes, you know freedom?
| |
| 09:44 | <robehend1> markit: haha, no
| |
| 09:44 | <evil_root> i encourage anyone to steal from microsoft
| |
| 09:44 | <robehend1> markit: reasons that apply to schools: is it cheap? Is it reliable? is there premade curriculum for it? can kids destory it
| |
| 09:44 | <muppis> "It can't be good if it's free"...
| |
| 09:45 | <robehend1> and the grand daddy of them:
| |
| 09:45 | Will teachers be able to use it with minimal training, upto and including the 60 year old spanish teacher who hates anything thats not an apple machine? if not, scrap it, go buy office 2010
| |
| 09:45 | <markit> muppis: Free not free
| |
| 09:45 | robehend1: apple fans are incredible, I know
| |
| 09:46 | <muppis> markit, I'm lazy in typing, when usiong N900..
| |
| 09:46 | <evil_root> god i am sorry robehend1, we actually have classes to teach end users
| |
| 09:46 | <robehend1> evil_root: i'm the single iT for the district, and they refuse to allow me to give staff development days,a s they'd rather focus on developing a new discipline setting, or plan for SnoDaze
| |
| 09:47 | <evil_root> ouch

| 09:47 | <markit> http://blogs.fsfe.org/ciaran/?p=110
| |
| 09:47 | <robehend1> so, when it comes to new software, i'm making multiple screencasts, going into studyhalls to give demo's to kids, driving to other buildings to do one on one step by step training wtih available staff, etc
| |
| 09:47 | <markit> expecialli from "Free Software has an especially important connection with Universities, and indeed all schools of all levels."...
| |
| 09:47 | <evil_root> lol we still have some districts with like 40 students total from kindergarden to 12th
| |
| 09:47 | <robehend1> oh stallman, that crazy bastard
| |
| 09:48 | evil_root: we're at about 800, k-12. but we're sitting on about..600 workstations, 12 servers, and numerous other fun things
| |
| 09:48 | <markit> robehend1: very unpolite comment
| |
| 09:48 | <robehend1> markit: not meant negatively. man's a genius, but you have to admit, he's quite...encentric
| |
| 09:49 | <markit> robehend1: my love for Free software derivates from his reasoning and the strenght of ethical reasons
| |
| 09:49 | <evil_root> i could not guess our end user amount, but we have about 30 servers dedicated to ltsp
| |
| 09:49 | <markit> otherwise I would have stayed with M$hell, much simpler to follow the bad trend
| |
| 09:49 | <evil_root> and the loadbalancer fails over to our cloud during really high load
| |
| 09:49 | <simbulu> what counts is your "ego" - how big is you budget? ( and you know is beautifull and better :-) )
| |
| 09:50 | <robehend1> nice. ive only got 4 ltsp boxes, one for each site, 3 of which are virtualmachines
| |
| 09:50 | <evil_root> using esxi?
| |
| 09:50 | <robehend1> simbulu: can't knock you there. its always a contest between the schools
| |
| 09:50 | evil_root: kvm.
| |
| 09:50 | <markit> evil_root: never had a look at ltsp clustering... is it reliable and "easy" to setup?
| |
| 09:50 | <evil_root> yes
| |
| 09:50 | and yes
| |
| 09:50 | one sec
| |
| 09:50 | <robehend1> evil_root: you using ldap to do authentication then/
| |
| 09:51 | <markit> robehend1: have you had a look at proxmox virtualization project?
| |
| 09:51 | <evil_root> yes robehend1

| |
| 09:51 | that walk threw works
| |
| 09:51 | <markit> evil_root: thanks
| |
| 09:51 | evil_root: but your experience is positive?
| |
| 09:52 | <robehend1> markit: never even heard of it
| |
| 09:52 | <evil_root> my experience is awesome, after i spent two weeks tweaking it the way i liked it, but yes out of the box its better than single host setup
| |
| 09:52 | <robehend1> evil_root: will i recieve benefits of running cluster on 2 virtual machines, hosted on the same physical box?
| |
| 09:52 | <evil_root> markit after you run threw entire setup and your logged on using it, on the app server run /etc/init.d/nscd restart
| |
| 09:53 | thats the only thing the walk threw is missing
| |
| 09:53 | no robehend1
| |
| 09:53 | <robehend1> ah,d arn
| |
| 09:53 | <evil_root> the point of the cluster is get the different services of the ltsp on boxes designed for it
| |
| 09:53 | like my nfs server has nothing for processor and ram
| |
| 09:53 | <robehend1> thats what i thought. just dont have any extra servers or budget at the moment
| |
| 09:53 | <evil_root> but shit loads of hard drives
| |
| 09:54 | and app servers
| |
| 09:54 | pxe boot and dont even have hard drives
| |
| 09:54 | but dual quad cores and 32G ram
| |
| 09:54 | Guest14144 has joined #ltsp | |
| 09:54 | <markit> urgh, 32GB... how many users?
| |
| 09:55 | <evil_root> 64 limit per app server
| |
| 09:55 | <Guest14144> in need of assistance with running vmware-view open client inside LTSP client
| |
| 09:55 | <markit> robehend1: I use proxmox, is really a joy, you install it in 15 minutes, and you have kvm + openvz virtualization and a web interface for setup and monitor
| |
| 09:55 | <evil_root> and thanks to out cloud, we have limitless app servers
| |
| 09:55 | <robehend1> markit: it bare metal, or require a os
| |
| 09:56 | <Guest14144> anybody out there with this knowledge?
| |
| 09:56 | <robehend1> Guest14144: whats going on/
| |
| 09:56 | <markit> robehend1: bare metal (destroy your hd content!)
| |
| 09:56 | robehend1: but you could also install on top of debian lenny yoruself
| |
| 09:56 | <Guest14144> followed instructions to install when client loads, i get a black screen with cursor in the upper left cornet
| |
| 09:56 | <robehend1> evil_root: are you booting your app servers off of ltsp then?
| |
| 09:56 | Guest14144: never used the vmware-view client, what are you trying to hook up to/
| |
| 09:56 | <Guest14144> PXE booting , yes
| |
| 09:57 | connecting to vmware view connection server
| |
| 09:57 | had it configured with rdp to windows XP, that worked great
| |
| 09:57 | <evil_root> yes i have the same tftp server for the thin clients that i do the app servers, but it serves a different image to the server vs the client
| |
| 09:57 | <robehend1> Guest14144: sadly, no idea. I've never tried it.
| |
| 09:58 | evil_root: ha, you have any documentation of this? i'd be interested in giving it a shot for my own curiosity
| |
| 09:58 | <Guest14144> if i chroot inside the client and install a new package, do i have to rebuild the client or perform some sort of update?
| |
| 09:58 | <evil_root> no i am not good with notes, lol it pisses my boss off so much
| |
| 09:58 | <robehend1> i've forced myself into it
| |
| 09:58 | <Guest14144> https://help.ubuntu.com/community/UbuntuLTSP/VMWareViewVDI
| |
| 09:59 | <robehend1> evil_root: but i'm assuming you basically made a fat-client chroot with all the apps you need, then boot the app servers off that?
| |
| 10:00 | Guest14144: out of curisoity, what does this setup accomplish? I'm working on something similiar with virtualbox at the moment, so it'd be worth it to try
| |
| 10:00 | <Guest14144> just built the ltsp server than build client image
| |
| 10:00 | to use with rdesktop
| |
| 10:00 | <evil_root> robehend1 i built one server and then used clonezilla to create the image and serve it
| |
| 10:00 | <Guest14144> then just installed vmware-view client as per above instructions
| |
| 10:01 | <robehend1> evil_root: ah..never played with clonezilla, i'm a FoG man myself, which doesnt do well with linux sadly
| |
| 10:01 | <evil_root> lol
| |
| 10:01 | <Guest14144> should launch vmware view to connect to VMware view connection manager
| |
| 10:01 | that determines which vdi you can connect to
| |
| 10:01 | <robehend1> hmm. no clue, sorry bud, never touched that system
| |
| 10:02 | <evil_root> and Guest14144 i know esx but i have never played with VMware view
| |
| 10:02 | <Guest14144> no problem but do i need to update my client image after installing software
| |
| 10:03 | or after adding packages
| |
| 10:03 | <evil_root> yes
| |
| 10:03 | <Guest14144> so when they ask you to chroot to the client path and install packages, always update after?
| |
| 10:04 | <muppis> Yes.
| |
| 10:04 | <evil_root> yes
| |
| 10:04 | <Guest14144> what's the proper syntax to update?
| |
| 10:04 | <robehend1> i update sometimes just for fun, when i'm feeling frisky
| |
| 10:04 | <evil_root> x86 or 64 bit clients?
| |
| 10:04 | <robehend1> sudo ltsp-update-image --arch *chroot name*
| |
| 10:04 | <Guest14144> awsome folks, will give that a try. could be my problem
| |
| 10:04 | thank you all
| |
| 10:05 | <muppis> And adding -i only updates the image.
| |
| 10:05 | <evil_root> welcome
| |
| 10:07 | <simbulu> playing around with ltsp, with little success. debian-edu will not start X, k12ltsp had hardly any docs, and the source (ltsp-trunk) would not compile the nbd-proxy parts.
| |
| 10:08 | I would like to get ltsp to work on Centos5.5 64 bit possibly on a xen box. Suggestions?
| |
| 10:09 | <Nubae> I´m working on getting it working on rhel 6
| |
| 10:09 | well attempting to at least
| |
| 10:09 | evil_root is now known as zz_evil_root | |
| 10:10 | <simbulu> would love to se ltsp on rhel6, even so it seems to be a while to wait for centos6...
| |
| 10:11 | <Nubae> sure, but one can respin rhel6 easily enough
| |
| 10:12 | problem is if u need rhn
| |
| 10:13 | <robehend1> zz_evil_root: so, if you dont mind, help me wrap my head around ltsp-cluster
| |
| 10:14 | <simbulu> I need an rpm based system - and prefer Centos these days (for a number of reasons)
| |
| 10:14 | <robehend1> zz_evil_root: the root server is the one providing tftp and such, correct?
| |
| 10:14 | <simbulu> even so I would not mind installing the ltsp from a tar ball
| |
| 10:14 | moobyFR has quit IRC | |
| 10:18 | <simbulu> the trunk has no .spec file ...perhaps I should go looking for a ltsp-NN.src.rpm

| 10:31 | <garymc> hi guys anyone know what free software there is so I can log into my work ltsp server via my mac whilst still in osx
| |
| 10:35 | <robehend1> garymc: you can ssh into it through terminal natively
| |
| 10:36 | garymc: besides that, y ou could setup a vnc connection, a NX connection, or install virtualbox and use a virtual client
| |
| 10:36 | <garymc> no i want to have the linux GUI loaded in a screen that i can flick on or off
| |
| 10:36 | when the network cable is attached
| |
| 10:37 | <robehend1> and vnc, or nx, will both give you a gui
| |
| 10:37 | <simbulu> Nubae, Do you have some ltsp/k12ltsp.*.src.rpm's to work from ?
| |
| 10:40 | <klausade> simbulu: where did debian-edu not want to start X? On the server, or on the thinclient?
| |
| 10:41 | <simbulu> klausade, X would not start on the server. It could not figure out how my lcd display works.
| |
| 10:43 | I might try again - with debian-edu on a virtual server (using Xen and Centos ...)
| |
| 10:43 | <klausade> simbulu: you tried the lenny based version? Probably X is too old for your server, but the thinclient should work just fine nevertheless.
| |
| 10:45 | simbulu: i never saw nobody manageing to run a ltsp-server on a virtual server, atleast not in a real big environment.
| |
| 10:45 | <simbulu> klausade, lenny I suppose (debian-edu-5.0.6+edu1-dvd.iso). I really do not want to fight with X any more.
| |
| 10:45 | <robehend1> simbulu: i'm running ltsp on a kvm server right now. its only supporting 25 clients, but is working fien
| |
| 10:45 | er, fien
| |
| 10:46 | gnunux has quit IRC | |
| 10:46 | <simbulu> Actually I have two hardware boxes and intend to run Centos 64 bit with xen on them - so having ltsp on a virtual server makes some kind of sense to me
| |
| 10:46 | <klausade> robehend1: try 500 clients.
| |
| 10:47 | <robehend1> klausade: ha, would love to. but thats what ltsp-cluster is for
| |
| 10:47 | dlezcano has quit IRC | |
| 10:47 | <simbulu> well I (my customer) will have 40 thin and 40 diskless clients - and some 100 others picking files from samba
| |
| 10:48 | <klausade> robehend1: well, we use something similar to loadbalance at our sites as well.
| |
| 10:49 | <simbulu> yes loadbalancing, testing, maintenance, etc. is what we like see on virtual servers.
| |
| 10:50 | if only I could say "yum install ltsp" and be done ...
| |
| 10:50 | <Nubae> well, just what´s available for fedora
| |
| 10:50 | debian is for sure easier

| |
| 10:51 | <simbulu> Nubae, Ok, I could run fedora under xen and have ltsp there. Right ?
| |
| 10:52 | <Nubae> klausade actually there are quite a few folks virtualising ltsp in their deployments
| |
| 10:52 | yep
| |
| 10:52 | I´m trying to see if I can rebuild for rhel6, but nothing is certain
| |
| 10:53 | <simbulu> Ok - in a few minutes the base system is ready and fedora can be installed
| |
| 10:54 | which version of fedora should we go for ?
| |
| 10:54 | <Nubae> I believe f14 is supported
| |
| 10:55 | f13 is more supported though

| |
| 11:01 | afaik nobody picked it up after warren left
| |
| 11:04 | komunista has joined #ltsp | |
| 11:04 | robehend1 has joined #ltsp | |
| 11:05 | <Nubae> well its supported for f13 at least, it seems
| |
| 11:05 | I´m not sure though, I´m just diving in myself cause need it for rhel6
| |
| 11:05 | might need to use f12 srpms then
| |
| 11:06 | how outdated is that?
| |
| 11:06 | <ogra> very i'd say
| |
| 11:06 | <Nubae> hmmm... so better to grab from source then
| |
| 11:07 | I fear could be a big job if u say that
| |
| 11:07 | <robehend1> since i'm getting high iostat reports, if i exported my homes to a nfs server, do you think that'd help?
| |
| 11:07 | <ogra> dont rely on me, i havent coded ltsp stuff since more than two years
| |
| 11:07 | about as long as fedora support dropped :)
| |
| 11:08 | there was a guy talking about taking up fedora work again about half a year ago on the ML but i dont think he has done anything

| 11:12 | <simbulu> ogra, sounds like that ltsp has no maintainer on fedora ?
| |
| 11:13 | <Nubae> jeez,,, no maintainer for fedora/redhat/centos then
| |
| 11:14 | sounds like it needs looking into
| |
| 11:14 | <simbulu> Hmm, that might lift an eyebrow at the school board ...
| |
| 11:14 | <robehend1> pfft, they dont gotta know ;0
| |
| 11:14 | ls
| |
| 11:15 | bah. alt tab, you are my nemesis
| |
| 11:15 | <Nubae> well they do if he wants rpm based support
| |
| 11:15 | unless u go for kiwi-ltsp of course
| |
| 11:16 | <ogra> simbulu, if you want well supported ltsp use ubuntu or debian
| |
| 11:17 | <Nubae> so we're back to ltsp being deb only... wow
| |
| 11:17 | <ogra> now ?
| |
| 11:18 | its like that since ages
| |
| 11:18 | warren left and nobody stepped up for fedora
| |
| 11:18 | <simbulu> mm - deb is fine - but not for me
| |
| 11:18 | <ogra> there is indeed still gentoo
| |
| 11:18 | not sure where that stands atm though
| |
| 11:19 | <simbulu> and I am the supporter - and happen to be an rpm guy. So they need fedora/rhel/centos/...
| |
| 11:19 | ( kiwi ....)
| |
| 11:19 | <ogra> well, feel free to pick up ltsp fedora maintenance
| |
| 11:19 | <Nubae> simbulu if u do, I could probably help out to some extent
| |
| 11:21 | <robehend1> how much of a server does something that only supplies nfs homes need?
| |
| 11:21 | spec wise, that is
| |
| 11:21 | <Nubae> depends on how many clients u want to serve
| |
| 11:21 | <simbulu> ogra, thank you for the offer :-) Right now I will just try to get the point where some thing works for me.
| |
| 11:23 | <robehend1> Nubae: say, 50 at a time
| |
| 11:25 | <Nubae> dual core for sure, quad core better
| |
| 11:25 | 8 gigs ram minimum
| |
| 11:25 | <robehend1> for just supplying home folders/
| |
| 11:25 | ?*
| |
| 11:25 | <Nubae> oh... not for ltsp?
| |
| 11:25 | <robehend1> nope, i just want to move my homes to a nfs server, so my ltsp server will be less burdened
| |
| 11:25 | i'm getting high disk-io
| |
| 11:26 | <Nubae> hmmm, u could also just put /home on a seperate disk
| |
| 11:26 | <robehend1> hmm, true
| |
| 11:26 | probably would make better sense, anyways
| |
| 11:27 | <Nubae> thats what I´ve done in the past
| |
| 11:27 | <robehend1> a standard Sata work for that, do i need to go up to SCSI
| |
| 11:27 | <Nubae> but nfs server shouldnt require too much, the bootlneck is probably the disks themselves
| |
| 11:27 | <robehend1> ya, i'd have to go check, but i think there your run of hte mill 7200rpms

| |
| 11:28 | <Nubae> well u can get 10,000 rpm satas, I´d go for that before going for scsi
| |
| 11:28 | but either might be overkill
| |
| 11:28 | <nosedrum> there is a chan on irc about resktop issue ono tse server ?
| |
| 11:28 | :D
| |
| 11:28 | <Nubae> depends how much they are being used...
| |
| 11:28 | <robehend1> Nubae: i'm getting spikes of 90%+ utilizations, when the kids are all on firefox and such, which causes freezing on the client end
| |
| 11:28 | so i'm trying to find a work around
| |
| 11:28 | <Nubae> nosedrum, really wish what u were trying to say...
| |
| 11:29 | wish I knew
| |
| 11:29 | well, I´d install firefox in the chroot
| |
| 11:29 | <nosedrum> Nubae: I'm searching some help about a tsclient/rdesktop issue
| |
| 11:29 | <robehend1> Nubae: already running fat-clients
| |
| 11:29 | <Nubae> having it run on the client will dfinetly help
| |
| 11:29 | <nosedrum> i know i'm not on the right chan
| |
| 11:29 | <Nubae> oh
| |
| 11:30 | <robehend1> Nubae: and have given them a 512mb nbdswap
| |
| 11:30 | hence my confusion
| |
| 11:30 | nosedrum: you trying to hook up to a windows 2008 box from rdesktop?
| |
| 11:30 | <Nubae> rdesktop.... try #rdesktop ?
| |
| 11:30 | <nosedrum> actually a win2003 box
| |
| 11:31 | #rdesktop not exist
| |
| 11:31 | i create it 5 min ago... -_-
| |
| 11:31 | <Nubae> heh
| |
| 11:31 | robhend1 are u swapping from server or clients?
| |
| 11:32 | <nosedrum> it's a strange issue who make me crazy... The happiness on mixed encironnement Linux/Windows...
| |
| 11:32 | <robehend1> Nubae: wish i could tell you. all i did was add NBD_SWAP = true in the lts.conf, and then edited the nbdwap.conf file for SIZE=512 , on the server
| |
| 11:33 | nosedrum: whats going wrong with it. i've been using rdesktop to get into win2003 daily for over 2 years
| |
| 11:33 | cliebow has joined #ltsp | |
| 11:33 | <nosedrum> robehend1: :D let's go for explain you
| |
| 11:34 | <Nubae> thats swapping from server
| |
| 11:34 | <nosedrum> I have a cluster of 2 win2k3 tse servers
| |
| 11:34 | <Nubae> i could try swapping on clients and that might help
| |
| 11:34 | <nosedrum> i can connect with rdesktop with no problem
| |
| 11:34 | 50 user on it
| |
| 11:34 | <robehend1> Nubae: and how would i set that up? btw, the clients only have 512mb ram, so ya
| |
| 11:34 | <Nubae> well the clients needs hard drives of course
| |
| 11:35 | <robehend1> Nubae: which they have
| |
| 11:35 | <cliebow> heh.. mine had 32
| |
| 11:35 | <robehend1> cliebow: haha, nice.
| |
| 11:35 | <cliebow> long ago and far away
| |
| 11:35 | <nosedrum> the problem is: when a user close the rdesktop windows with right cross ==> tse session immediatly end on 2k3 server
| |
| 11:35 | <Nubae> if they have that, check the ubuntultsp wiki, think there is a blurb about client side swapping
| |
| 11:35 | <robehend1> Nubae: hmm, ok.
| |
| 11:35 | <nosedrum> and the same scenario with the original windows rdp client => the session is keep on server and you can reconnect
| |
| 11:35 | you understand ?
| |
| 11:35 | <robehend1> was hoping i wouldnt need hard drives in these things. i'm not 100% sure why they're cashing
| |
| 11:36 | nosedrum: yes, i understand, and i dont have that issue. my sessions persist
| |
| 11:36 | <nosedrum> -_-
| |
| 11:36 | and it's not the gpo because with the windows rdp client it works...
| |
| 11:36 | <robehend1> sorry bud. might try an rdesktop mailing list or something
| |
| 11:36 | <Nubae> well u´re other optin is what u suggest, nfs server, but that doesnt rule out the cpu spikes
| |
| 11:36 | <nosedrum> sure
| |
| 11:36 | <klausade> robehend1: for high IO values when they are using FF, try to use "browser.safebrowsing.malware.enabled", false and "browser.safebrowsing.enabled", false. We have seen just 100 simultaneous logons kill the disk otherwise (thats 15K sas disks)
| |
| 11:36 | <nosedrum> i already do that
| |
| 11:36 | thx for listen me...
| |
| 11:37 | good vibes guys
| |
| 11:37 | <robehend1> klausade: can i set that in the firefox.js file?
| |
| 11:37 | <klausade> robehend1: yes.
| |
| 11:37 | <robehend1> now to go relearn that syntax
| |
| 11:37 | klausade: have you attempted to use Chromium in lue of firefox, to see if it gives you the same issues?
| |
| 11:38 | <klausade> robehend1: no, to much retraining, and our LMS and a ton of on-line teaching material only works/is supported on FF.
| |
| 11:38 | <robehend1> ah, understandable. i had to update my LMS for chrome, due to home users wanting it

| 11:40 | <robehend1> and ewww, subscribed lmS. Thats why i went and bought a moodle server ;)
| |
| 11:40 | <klausade> robehend1: yes, go Moodle!
| |
| 11:40 | <Nubae> moodle rocks!
| |
| 11:41 | <robehend1> been using it for 5 years now, no complaints except its dismal login speed
| |
| 11:41 | <simbulu> ogra, btw - there exist deb2rpm utilities I could use. Then I would just have to find the proper deb files first :-)
| |
| 11:41 | <ogra> simbulu, that doesnt help
| |
| 11:41 | <klausade> robehend1: but, to much retraining, and not realy anybody around to sell us support and training (in Norway).
| |
| 11:41 | <ogra> ltsp is integrated with the distros
| |
| 11:41 | <Nubae> simbulu dont think its that simple
| |
| 11:41 | <robehend1> ya, understood. i had to make most of my training, since they dont want to buy anything ;0
| |
| 11:41 | <markit> oh, moodle, I've the feeling that is interesting, but also the feeling that teacher IT culture, at least here, is so low that will never be used
| |
| 11:41 | <ogra> you cant just re-use packages from one on the other
| |
| 11:42 | <robehend1> markit: it autogrades tests, if you set it up right
| |
| 11:42 | <ogra> thats the whole purpose of ltsp4
| |
| 11:42 | <Nubae> u could however take a look at the deb sources
| |
| 11:42 | <markit> also I've not got a precise idea of what can be done with it, need to grab info online
| |
| 11:42 | <ogra> errr
| |
| 11:42 | ltsp5
| |
| 11:42 | alkisg has joined #ltsp | |
| 11:42 | <simbulu> ok - nothing seems to be simple ... Installing a minimal fc14 box ... and going for a swim
| |
| 11:42 | <ogra> Nubae, wont help if the underlying tecnology differs
| |
| 11:43 | <markit> robehend1: teachers here can hardly use PC, they only knwo windows and don't understand that you have a spreadsheet, not an "excel", and so on
| |
| 11:43 | <Nubae> sure, but its a starting point
| |
| 11:43 | <ogra> the source is the best starting point
| |
| 11:43 | and fix the missing bits for fedora
| |
| 11:43 | <Nubae> well compare it to the source I meant
| |
| 11:43 | <robehend1> markit: preaching to the choir. i had to make the classic 'step by step, click here than here" videos for pretty much every thing
| |
| 11:43 | <_UsUrPeR_> hey all.
| |
| 11:43 | <robehend1> heyo
| |
| 11:43 | <_UsUrPeR_> nubae: quick question about fatclient
| |
| 11:43 | <ogra> source is definitely better
| |
| 11:43 | <_UsUrPeR_> have you attempted to get a fat lcient image working in LTSP cluster?
| |
| 11:44 | <Nubae> of course that would be the starting point, I meant look at deb sources to see where we are now
| |
| 11:44 | _UsUrPeR_ nope
| |
| 11:44 | <_UsUrPeR_> err "fat client" I should say
| |
| 11:44 | <klausade> robehend1: we have two huge LMS vendors here in Norway, and both pull your money out through your nose, and plenty of people want an alternative.
| |
| 11:44 | <ogra> sure, other distros are surely good for comparison
| |
| 11:44 | <markit> robehend1: do you think a video is a good solution? do they watch it? I'm just preparing a brief notes about server on/off/troubleshoot and GNU/linux differences, I suppose they will not understand more than 1%, sigh
| |
| 11:44 | <simbulu> looked at sources in ltsp-trunk . Can not say it was very usefull.
| |
| 11:44 | <_UsUrPeR_> Nubae: one more question: if a fat client is authenticating with ldap, does that mean that ldap needs to be installed on the client image?
| |
| 11:45 | <robehend1> markit: they liked videos, becuase they could watch them at home or anywhere, since its all on our Google Video account.
| |
| 11:45 | <simbulu> (to me - that is)
| |
| 11:45 | <Nubae> a part of ldap, yeah
| |
| 11:45 | the ldap client :-)
| |
| 11:45 | <robehend1> klausade: i'd go with moodle. its having great luck here in the states, and i've had great luck deploying it to many schools
| |
| 11:45 | <_UsUrPeR_> Nubae: ok. Thanks.
| |
| 11:45 | <markit> robehend1: do you mind give me access to them? just to take inspiration
| |
| 11:45 | <alkisg> _UsUrPeR_: no, in normal ltsp ldm is used, so the client can't use ldap directly
| |
| 11:45 | <robehend1> markit: would if i could. We finished training on moodle last year, and removed the videos, as we only have 10 gigs of space :(
| |
| 11:45 | <alkisg> It goes through the server
| |
| 11:45 | <Nubae> fat clients alkisg
| |
| 11:45 | <robehend1> markit: let me see if I've got em around on a fileserver
| |
| 11:46 | <alkisg> Nubae: yes, still ldm
| |
| 11:46 | <_UsUrPeR_> alkisg: This is fat client specific
| |
| 11:46 | ORLY
| |
| 11:46 | <Nubae> not mine they dont
| |
| 11:46 | <alkisg> _UsUrPeR_: you mean the ubuntu implementation of fat clients, right?
| |
| 11:46 | !fatclients
| |
| 11:46 | <Nubae> they use ldap on the client
| |
| 11:46 | <ltspbot> alkisg: "fatclients" :: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
| |
| 11:46 | <alkisg> Or the old, nubae's implementation?
| |
| 11:46 | <Nubae> he probably means new
| |
| 11:46 | <_UsUrPeR_> I guess I was not aware that there was a difference
| |
| 11:46 | <Nubae> :-=
| |
| 11:46 | <_UsUrPeR_> new I suppose
| |
| 11:47 | <Nubae> there isnt much difference
| |
| 11:47 | other than I have nothing to do with it anymore :p
| |
| 11:47 | <_UsUrPeR_> lol
| |
| 11:47 | ok
| |
| 11:48 | I guess I am going to have to give this a shot from a first-person perspective. To reiterate: this is using ldap to authenticate.
| |
| 11:48 | <alkisg> ldm can't use ldap
| |
| 11:48 | So anything ldap related happens on the server
| |
| 11:48 | If you want, you can stop using ldm and start using gdm, but you'll lose all LDM* variables from lts.conf
| |
| 11:49 | <_UsUrPeR_> Nubae / alkis: when is the "new" fat client implemented?
| |
| 11:49 | 10.04? 10.10
| |
| 11:49 | ?
| |
| 11:49 | <Nubae> what about other authentication in the fat client then?
| |
| 11:50 | <alkisg> I think we got most of it upstream for 10.04
| |
| 11:50 | There are backports for 9.10, but not official ones
| |
| 11:50 | Nubae: what other authentication?
| |
| 11:50 | There's no difference in authentication between thin or fat clients
| |
| 11:50 | It's exactly the same
| |
| 11:50 | <_UsUrPeR_> alkisg: have you attempted to use either version of fat client with ltsp-cluster>?
| |
| 11:50 | <alkisg> No, I've never seen ltsp-cluster
| |
| 11:51 | <Nubae> oh right no local passwd/shadow and group
| |
| 11:51 | thinking about my horrible hack again
| |
| 11:51 | <alkisg> Nubae: right, i don't think there are any similarities in your implementation of fat clients and the upstream one
| |
| 11:52 | <Nubae> well no, the only difference is authentication
| |
| 11:52 | everythin else is the same
| |
| 11:52 | printer support, sounds, etc
| |
| 11:53 | <alkisg> The ltsp-build-client plugin was written from scratch without looking at your sources, and there's no code for printer/sound etc other than a simple if
| |
| 11:53 | (to disable remote pulse for fat clients)
| |
| 11:54 | <Nubae> its still the same code... sound, printers, etc didnt change
| |
| 11:54 | <alkisg> What do you mean about sound?
| |
| 11:54 | Fat clients don't have any special sound support...
| |
| 11:54 | <Nubae> puolse on the client
| |
| 11:54 | <alkisg> They're just standalone ubuntu installations wrt sound
| |
| 11:54 | markit has quit IRC | |
| 11:55 | <Nubae> no, it does require some settings to get it working... i remember, unless its changed
| |
| 11:55 | i havent looked at the code in years
| |
| 11:55 | <alkisg> I don't think we put anything for sound, except for an "if it's fat, don't touch sound settings"
| |
| 11:55 | <simbulu> The latest rpm I can find for fedora is ltsp-5.1.95-1.fc13.src.rpm. I will give it a go on fc14
| |
| 11:56 | <Nubae> well, wehn i looked way back when i remember it being the same
| |
| 11:57 | <_UsUrPeR_> ok, well thanks. I think this answered a few questions
| |
| 11:57 | <Nubae> wonder who maintained fc13 if it wasnt warren
| |
| 12:00 | <simbulu> Nubae, Looks like Warren built this thing on Des 03 2009
| |
| 12:04 | <Nubae> so 1 year
| |
| 12:04 | thats still ok
| |
| 12:05 | <ogra> heh
| |
| 12:05 | you think ltsp development stood still for 1 year ?
| |
| 12:05 | <Nubae> better than 2 at least :p
| |
| 12:06 | <ogra> ltsp is at 5.2.5 in ubuntu
| |
| 12:06 | 5.1.95 is a 5.2 pre-release
| |
| 12:09 | <simbulu> well - seems like mandriva has ltsp-server-5.2-2
| |
| 12:10 | 5.2.4-2 seems to be current version (on deb)
| |
| 12:10 | <Nubae> really? who maintains that?
| |
| 12:12 | <simbulu> The Changelog mentions Funda Wang, Oden Eriksson on 2010-12-07
| |
| 12:12 | <Nubae> well we should talk to them i guess

| |
| 12:14 | Nubae is now known as Nubae_away | |

| |
| 12:23 | simbulu, they have kiwi which is a very different wrapper around the ltsp scripts
| |
| 12:25 | <simbulu> ok - I am no suse expert - cf. http://download.opensuse.org/repositories/server:/ltsp/openSUSE_Factory/src/ltsp-5.2.4-4.14.src.rpm
| |
| 12:26 | <ogra> right, it doesnt work without the kiwi wrapper

| 12:28 | <robehend1> alkisg: say, question. even after enabling nbdswap on the clients, i'm still getting lockups on firefox and such on fat clients. have some higher utilization in iostat for the hard drive, but i'm wondering if it could be anything else i should check before moving /home to another disk,nfs, etc
| |
| 12:28 | <simbulu> well - seems like everyone wraps ltsp differently ...
| |
| 12:29 | <ogra> not ubuntu, debian, fedora and gentoo
| |
| 12:29 | toscalix has joined #ltsp | |
| 12:29 | <ogra> the prob is just that fedora fell behind
| |
| 12:29 | i didnt know about mandriva and its sad they didnt talk to upstream at all
| |
| 12:29 | <simbulu> anyway - my fc14 box is ready and says:
| |
| 12:31 | that 5.1.95-1.fc13 versions of ltsp-client{-client,-server,-vmclient,fs,fsd} are available from the fedora repo.
| |
| 12:32 | <ogra> right, 5.1.95 will just miss a bunch of fixes
| |
| 12:32 | but ltsp-build-client (and all its friends) should work
| |
| 12:33 | <simbulu> well - I have to work with what is available, for a start
| |
| 12:34 | <ogra> sure
| |
| 12:36 | Gremble has joined #ltsp | |

| |

| |
| 12:37 | no
| |
| 12:37 | <simbulu> ldm should be a LTSP Display Manager
| |
| 12:37 | <ogra> you only install one package, read the docs for your distro
| |
| 12:38 | <simbulu> ok - I will :-)

| |
| 12:38 | oops, sorry, cat attack
| |
| 12:39 | just make sure to never ever install any ltsp-client package on your server
| |
| 12:39 | the scripts need to do that in the right place, else you will mess up your server install
| |
| 12:42 | <simbulu> "yum install ltsp-server" (installing 123 packages ...)

| |
| 13:34 | rthomson has joined #ltsp | |
| 13:35 | <_UsUrPeR_> right now, my server doesn't seem to be starting tftp. I am not finding a pid created for tftpd-hpa
| |
| 13:35 | neither in a ps -aux OR in /var/run
| |
| 13:36 | <ogra> it was always handled by inetd
| |
| 13:36 | not sure that was changed recently
| |
| 13:37 | <_UsUrPeR_> ogra: yeah. Even starting manually, this doesn't seem to be working properly
| |
| 13:37 | just "in.tftpd --listen"
| |
| 13:37 | <ogra> how would you start it manually ?
| |
| 13:37 | <_UsUrPeR_> ^^
| |
| 13:38 | <rthomson> Does it make sense that quickly scrolling around an average PDF file in Adobe Reader 9 on our thin clients can easily use ~60-80Mbps bidirectionally between the client and server? LTSP5, LDM_DIRECTX=True.
| |
| 13:38 | <ogra> well check if /etc/default/tftpd-hpa changed over the upgrade
| |
| 13:38 | <_UsUrPeR_> rthomson: yes. That's full screen refreshes in your native screen resolution
| |
| 13:39 | ogra: no, nothing is different in there :/
| |
| 13:39 | <rthomson> _UsUrPeR_, thanks that's what I thought as I didn't think nload was lying to me
| |
| 13:40 | <_UsUrPeR_> rthomson: I would recommend running as a local application
| |
| 13:40 | that would stop your network from being eaten up by moving the processing onus from your server to your client
| |
| 13:40 | <rthomson> Yeah, I've been testing that out
| |
| 13:40 | <_UsUrPeR_> which will keep the image off the network, instead relying solely on the processing power and resources inside your client.
| |
| 13:41 | <rthomson> Works pretty well on my thin-client-thats-really-a-PC but I haven't tested with our atom-based LTSPTerms yet.
| |
| 13:44 | <_UsUrPeR_> rthomson: you will notice a drop in speed, but your network will thank you :)
| |
| 13:44 | <robehend1> rthomson: i've ran thinclients on atom machines. completely usuable
| |
| 13:45 | <alkisg> (08:28:24 PM) robehend1: alkisg: say, question. even after enabling nbdswap on the clients, i'm still getting lockups on firefox and such on fat clients. have some higher utilization in iostat for the hard drive, but i'm wondering if it could be anything else i should check before moving /home to another disk,nfs, etc
| |
| 13:45 | ==> firefox lockups? Or complete OS lockups?
| |
| 13:45 | <robehend1> alkisg: firefox lockups, it appears. but, of course, whenever it stops working, the students answer is "click on it until it works"
| |
| 13:45 | <rthomson> robehend1: yeah, we've got a couple LTSPTerm1720s and they are pretty good
| |
| 13:46 | <alkisg> _UsUrPeR_: to start tftp, the command is: sudo start tftpd-hpa
| |
| 13:46 | <rthomson> but with dual 1680x1050 monitors attached, there can be a lot of network traffic
| |
| 13:46 | <alkisg> _UsUrPeR_: `sudo status tftpd-hpa` for the status, and check syslog for errors
| |
| 13:46 | <_UsUrPeR_> alkisg: it states that the job is already running. Same as /etc/init.d/tftpd-hpa status
| |
| 13:46 | it just does not list a PID
| |
| 13:47 | <robehend1> alkisg: i did go in and add the firefox3 optimizations found https://help.ubuntu.com/community/UbuntuLTSP/Firefox3Optimize, and am going to see if that makes a difference.
| |
| 13:47 | <_UsUrPeR_> nor is one created in /var/run. Is there supposed to be a PID created?
| |
| 13:47 | <alkisg> _UsUrPeR_: try stopping it first. sudo stop tftpd-hpa
| |
| 13:47 | And then starting it again. I've seen upstart getting mixed up...
| |
| 13:48 | <_UsUrPeR_> alkisg, ok, one moment
| |
| 13:48 | <alkisg> robehend1: optimizations should be unrelated to firefox crashes, though
| |
| 13:49 | <_UsUrPeR_> Hmm. It says the process stopped then started, but I am not seeing anything for a PID, can't find the tftp related in ps aux, nor am I seeing anything listening with a netstat -anp |grep 69
| |
| 13:49 | <robehend1> alkisg: well, evil_root had me take a look at my iostat, and we noticed some spikes. figured by turning the cache off, it wouldnt be utilizing it as much/
| |
| 13:51 | <alkisg> _UsUrPeR_: check the logs
| |
| 13:51 | If might be telling you there why it doesn't start
| |
| 13:51 | mutex has joined #ltsp | |
| 13:51 | <alkisg> robehend1: sure, optimizations are good. But their lack shouldn't result in crashes
| |
| 13:53 | <_UsUrPeR_> alkisg: /var/log/syslog -- "in.tftpd[PID]: Cannot set nonblock flag on socket: baad file descriptor"
| |
| 13:53 | <alkisg> Google for that message... :)
| |
| 13:53 | <_UsUrPeR_> :P
| |
| 13:53 | ok :)
| |
| 13:56 | <robehend1> alkisg: thats my thought to. espicially since its on fat clients
| |
| 14:02 | [GuS] has quit IRC | |
| 14:02 | <robehend1> alkisg: i'm also seeing if i can replicate it in chromium, as i'm thinking they both would use a similiar amount of disk io
| |
| 14:03 | <alkisg> robehend1: so you think that the problem is disk io related?
| |
| 14:03 | Or could it be graphics related, or ram related, etc?
| |
| 14:03 | <robehend1> alkisg: well, they ahd me run iostat, and i did see some spikes up in the 90-100% range, for areas of 5-10 seconds. usually when i had the most users logged in
| |
| 14:03 | alkisg: and the users homes are currently on teh same disk as the server itself
| |
| 14:04 | <alkisg> And what part of all this isn't normal behavior?
| |
| 14:04 | <robehend1> alkisg: no idea. I dont have a baseline for normal behavoir, hence just providing what information i have avaiable
| |
| 14:05 | <alkisg> After firefox crashes, everything else works normally?
| |
| 14:05 | <robehend1> alkisg: its not so much as one of those 'not responding' lockups. if i forge quit it, it usually goes fine
| |
| 14:06 | <alkisg> Try passing "nolock" as an nfs mount option, and see if that works around the problem
| |
| 14:06 | <robehend1> alkisg: where would I add that? I thought fat-clients ran ssfs
| |
| 14:07 | eh, sshfs*
| |
| 14:07 | <alkisg> Ah, I thought you were using NFS?
| |
| 14:07 | Nothing NFS related in your installation?
| |
| 14:07 | <robehend1> no, setting up NFS homes if our next step, if it cant be figured out
| |
| 14:07 | not a thing
| |
| 14:07 | i'm on a bog standard fat-client install
| |
| 14:07 | <alkisg> Hmmm....
| |
| 14:07 | Any atheros NICs?
| |
| 14:08 | NM that problem is also with NFS
| |
| 14:08 | <robehend1> maybe one or two, but mostly broadcoms
| |
| 14:08 | <alkisg> Hmmmm again....
