| 03:11 | <vlt> Hello. On some clients I need /var/spool to be mounted with much larger size than the default value of half the RAM (yes, I got swap over NBD). Any idea what to edit here?
| |
| 03:15 | <vagrantc> vlt: ubuntu, debian, or ?
| |
| 03:16 | <vlt> vagrantc: Ubuntu (Dapper 6.06)
| |
| 03:17 | <vagrantc> vlt: using ltsp5 and such ?
| |
| 03:18 | <vlt> vagrantc: according ogr_a it should be v5
| |
| 03:18 | <vagrantc> just want to make sure you're not using ltsp-utils and ltspadmin and stuff

| 03:20 | <vagrantc> vlt: look for a line in /opt/ltsp/i386/etc/init.d/ltsp-client-setup like this: mount -t tmpfs -o mode=0755 tmpfs $tmpfs_dir
| |
| 03:20 | <vlt> vagrantc: I already unzipped /opt/ltsp/i386/initrd... but can't find exactly where to place the size paramater for the ...
| |
| 03:20 | vagrantc: Yes, found the line
| |
| 03:20 | <vagrantc> vlt: change it to: mount -t tmpfs -o mode=0755,size=XXXXm tmpfs $tmpfs_dir
| |
| 03:21 | <vlt> vagrantc: I'll try, thank you.
| |
| 03:21 | <vagrantc> where XXX is the number of megabytes of ram
| |
| 03:21 | <vlt> vagrantc: Any quick idea how to apply this to certain clients only?
| |
| 03:21 | <vagrantc> vlt: nope
| |
| 03:22 | <vlt> ok
| |
| 03:22 | <vagrantc> well, actually ...
| |
| 03:22 | you could set some sort of variable in lts.conf
| |
| 03:23 | and then put the size stuff in an if statement
| |
| 03:23 | <vlt> vagrantc: Aah, yes, sounds good.
| |
| 03:24 | <vagrantc> if [ "$SOME_VARIABLE" = "true" ]; then mount -o remount,size=XXXXm $tmpfs_dir ; fi
| |
| 03:24 | something like that
| |
| 03:25 | dapper is kind of antique for LTSP
| |
| 03:26 | i'd best get some sleep

| 03:56 | <vlt> Hello (ogra), now that Ubuntu 7.10 is out would you reccommend "upgrading" from 6.06 LTS in a production LTSP environment?

| |
| 08:43 | <jammcq> doing great
| |
| 08:43 | how's things there?
| |
| 08:44 | <rjune_> I'm doing well, Jen and Morgan are sick.
| |
| 08:44 | <jammcq> bummer
| |
| 08:44 | <rjune_> which means Jen's remembering why it is she married me right now. :-)

| |
| 08:58 | exodos: Hellooooo?
| |
| 08:58 | <jammcq> heh
| |
| 08:59 | sbalneav: check your microphone, maybe it's not turned on :)
| |
| 08:59 | * sbalneav taps microphone | |
| 08:59 | <sbalneav> Is this thing on... Is this thing on...
| |
| 08:59 | <jammcq> nope, can't hear you
| |
| 08:59 | <sbalneav> Who is it who does that in their comedy routine?
| |
| 08:59 | <jammcq> umm
| |
| 08:59 | every comedian on a bad night
| |
| 08:59 | <sbalneav> heh
| |
| 09:00 | well, yeah.
| |
| 09:00 | But there's one who does it all the time in his act. It'll come to me eventually.
| |
| 09:03 | exodos: Pinging again...
| |
| 09:08 | pwest has joined #ltsp | |
| 09:08 | <sgonzalez> sbalneav: I'm not exodus, but I'll answer ;) Good morning. Last week we chatted a bit about the server freezing on me and you suggested a memtest86. In 48 hours it finished 39% of the test with no errors. I don't have 4 days to let it run until we get to Thanksgiving. However, I'm skeptical about memory being the issue. I talked to David Trask (tech person at school in Maine running edubuntu). He doesn't run kernel because it doesn't work for him either
| |
| 09:08 | . I would really like my 6gb... any other thoughts? (sorry for the really long post!)
| |
| 09:09 | <pwest> Is it possible to change the interface language of the LDM to, in this case, German?
| |
| 09:10 | <sbalneav> pwest: I don't think there were any translations done for de yet.
| |
| 09:11 | <pwest> okay, so it can't yet be changed
| |
| 09:11 | <sbalneav> sgonzalez: None. This is a server kernel issue, so I'd simply file a bug.
| |
| 09:11 | pwest: Yeah, by next time, I'd expect we'll have a fuller set of translations.
| |
| 09:11 | <pwest> I thought it would be a matter of installing a language-pack and setting some locale variable
| |
| 09:11 | great thanks for the info
| |
| 09:12 | <sbalneav> Well, it would be.
| |
| 09:12 | <pwest> but
| |
| 09:12 | <sbalneav> but if the strings aren't translated, then there's nothing to sub in :)
| |
| 09:12 | <rjune_> pwest: sounds like a translator is needed.
| |
| 09:12 | <sbalneav> Plus, it's entirely possible that my i18n work I did on LDM is completely and utterly wrong :)
| |
| 09:13 | <pwest> okay, I assumed it would grab strings from the GDM trl's
| |
| 09:13 | <sbalneav> seeing as how I have no clue as to how to do i18n in C :)
| |
| 09:13 | <pwest> let's hope not
| |
| 09:13 | <sbalneav> I followed some examples, and crossed my fingers.
| |
| 09:14 | <sgonzalez> sbalneav: I meant to ask you this at the beginning: Are you the right person to ask these types of questions? You tend to have answers so I keep asking you, but let me know if I should bug someone else! And where do I file a bug (another question... sorry!)
| |
| 09:14 | <sbalneav> I'll leave it up to people who need other languages to check my work and send me patches :)
| |
| 09:15 | sgonzalez: Well, launchpad's the place to file bugs for ubuntu/edubuntu, and I try to help as much as I can, but this isn't anything I know about in detail. I have IBM X series servers, and the -server kernels work fine for me, so there's not much I can offer.
| |
| 09:15 | <pwest> I'm just a foriegner here in Germany myself, so I can't really do great trl'ing
| |
| 09:15 | Clown-MG has joined #ltsp | |
| 09:16 | <sgonzalez> Thanks :) I'll go look on launchpad and see what I can find there.
| |
| 09:16 | <sbalneav> I'm pretty much at the point where we should all just learn to speak and read/write esperanto. Think of the amount of coding it would save! :)
| |
| 09:17 | Plus, I found a poster on the weekend telling me how to order a beer in Esperanto, so I'm pretty much set now :)
| |
| 09:17 | <pwest> thanks for your work

| 10:28 | <sunru> hi
| |
| 10:29 | <sbalneav> Hello sunru
| |
| 10:30 | <sunru> ok i've just realized i've been reading the 4.0 docs
| |
| 10:31 | sbalneav: hi just a bit stuck on the whole root mounting part.
| |
| 10:33 | <sbalneav> Well, first off, how about telling us what version of ltsp you're running on what server?
| |
| 10:34 | <sunru> server running gentoo
| |
| 10:34 | LTSP-5?
| |
| 10:34 | <jammcq> you wish
| |
| 10:34 | ltsp-5 doesn't exist on gentoo yet
| |
| 10:34 | it's prolly ltsp-4.2 you have
| |
| 10:37 | <sunru> how does the client have access to the server applications? is the root in /opt/ltsp/ temporary?
| |
| 10:37 | <jammcq> the client doesn't have access to those apps
| |
| 10:37 | <sunru> i'm just stuck on that bit.
| |
| 10:37 | <jammcq> you use the thin client to log into the server
| |
| 10:37 | you run all apps ON the server
| |
| 10:37 | but they are displayed on the client. the miracle of the X Window System
| |
| 10:37 | <sunru> yes i know that.
| |
| 10:38 | <jammcq> if you know that, then why are you asking how the client has access to the apps?
| |
| 10:38 | <sunru> what are the client roots in /opt/ltsp/
| |
| 10:38 | <jammcq> thats the root filesystem for the client
| |
| 10:38 | /opt/ltsp/i386 is mounted via NFS on the client
| |
| 10:39 | elisboa has quit IRC | |
| 10:39 | <sunru> ok
| |
| 10:39 | <jammcq> but there's no applications there
| |
| 10:39 | only operating system things
| |
| 10:39 | <sunru> so for the client to "execute" /usr/bin/oowriter on the client requires /usr to be mounted via NFS?
| |
| 10:40 | <jammcq> no
| |
| 10:40 | <sunru> on the server rather.
| |
| 10:40 | <jammcq> you don't get it. the client doesn't "execute" oowriter
| |
| 10:40 | the user actually has a session on the server
| |
| 10:40 | the SERVER "executes" oowriter
| |
| 10:41 | <rjune_> I executed oowriter.
| |
| 10:41 | <sunru> are you done making corrections on symantecs?
| |
| 10:41 | <rjune_> the sumbitch was using too much RAM
| |
| 10:41 | <jammcq> sunru: you are asking how things work. I'm telling you
| |
| 10:41 | but it seems you don't understand
| |
| 10:41 | <sunru> jammcq: no your being a smartass
| |
| 10:42 | <rjune_> uh oh
| |
| 10:42 | <jammcq> i'm trying to help you here
| |
| 10:42 | I'm telling you the apps don't run on the client
| |
| 10:42 | elisboa has joined #ltsp | |
| 10:43 | <sunru> so is /usr mounted via NFS ?
| |
| 10:43 | <jammcq> when you log in via a thin client, your entire session is running on the server
| |
| 10:43 | Gnome, KDE, whatever, it's all running on the server, displaying it's output on the client
| |
| 10:43 | <sunru> jammcq: NO SHIT!
| |
| 10:43 | <jammcq> NO, /usr is not mounted via NFS
| |
| 10:43 | <sunru> typical IRC wanker
| |
| 10:43 | <jammcq> only /opt/ltsp/i386 is mounted
| |
| 10:44 | ok, someone else wanna explain to this guy how it works. apparently i'm not able to
| |
| 10:44 | <Blinny> Wow.
| |
| 10:44 | <cyberorg> sunru, btw jammcq is the smartass who started whole of ltsp project that we all love
| |
| 10:44 | <rjune_> magic.
| |
| 10:44 | <Blinny> sunru: Checkit. The client boots and yes, there is a minimal system mounted via NFS or NBD
| |
| 10:44 | <rjune_> it works on magic
| |
| 10:45 | <sunru> so server /usr is a symlink -> /opt/ltsp/i386?
| |
| 10:45 | so server /usr is a symlink -> /opt/ltsp/i386/usr
| |
| 10:45 | <jammcq> no
| |
| 10:45 | <Blinny> sunru: However, that system is only there to open a connection to the server. When you run something (OpenOffice, FireFox, etc) you're running applications directly on the server. There is no symlink, there is no mounting.
| |
| 10:45 | <jammcq> why does the thin client need /usr ?
| |
| 10:45 | answer.... it doesn't
| |
| 10:45 | <Blinny> You_work_on_the_server.
| |
| 10:45 | sunru: Think of it as a very long cable for your mouse, keyboard and monitor, connected directly to the server.
| |
| 10:45 | <sunru> gawd
| |
| 10:45 | <Blinny> That's what the software does. Just makes a very long software cable.
| |
| 10:46 | So, if you have GIMP installed on the server, you can run it from the client.
| |
| 10:46 | <sunru> yes i know.
| |
| 10:46 | <Blinny> If you have ____ installed on the server, you can run it from the client.
| |
| 10:46 | <jammcq> "From" the client, but not ON the client
| |
| 10:46 | <sunru> yes i know.
| |
| 10:46 | <jammcq> ok, then what's the problem?
| |
| 10:47 | <Blinny> The questions you're asking don't jive with you knowing that point.
| |
| 10:47 | <sunru> /opt/ltsp/i386/usr is mounted via NFS as / on the client correct?
| |
| 10:47 | <jammcq> no
| |
| 10:47 | but you are close
| |
| 10:47 | /opt/ltsp/i386 is mounted as /
| |
| 10:47 | <sunru> ugh sorry i meant that.
| |
| 10:48 | sigh
| |
| 10:48 | * rjune_ bows to jammcq. You're *VERY* patient | |
| 10:48 | <sunru> the problem is i know you know what im trying to get at.
| |
| 10:49 | <jammcq> umm, apparently I don't, cuz we have this "mismatch of ideas" here
| |
| 10:49 | have you tried it yet?
| |
| 10:49 | <sunru> on the server oowriter is in /usr/bin/
| |
| 10:49 | <jammcq> yes
| |
| 10:49 | probably there
| |
| 10:50 | <sunru> right so where is it in /opt/ltsp/i386?
| |
| 10:50 | <jammcq> it's not
| |
| 10:50 | doesn't need to be
| |
| 10:50 | only thing the thin client needs is a kernel, some libraries, a shell, and the X stuff
| |
| 10:50 | with that, you can connect to the server and get a session running on the server
| |
| 10:51 | so now, your session is executing on the server's CPU.
| |
| 10:51 | all apps you run are running on the server, not the client
| |
| 10:51 | the client just gets you there
| |
| 10:51 | <nonsparker> jammcq: does it work the same way with kiosk?
| |
| 10:51 | <sunru> oh ic
| |
| 10:51 | jammcq: im sorry for the misunderstanding.
| |
| 10:51 | <jammcq> nonsparker: kiosk means alot of things to alot of people
| |
| 10:51 | sunru: ok then, you starting to understand it?
| |
| 10:52 | <sunru> yes
| |
| 10:52 | <jammcq> cool
| |
| 10:52 | <nonsparker> the build-kiosk
| |
| 10:52 | <jammcq> nonsparker: sorry, dunno about that
| |
| 10:52 | <sunru> i removed X from the equation
| |
| 10:52 | nonsparker: i cant see why not?
| |
| 10:52 | <Blinny> sunru: In the future, you may wish to keep 'wanker' from your vocabulary when you're asking for help.
| |
| 10:52 | <nonsparker> ltsp-build --kiosk
| |
| 10:53 | <sunru> Blinny: sorry me and IRC don't mesh to well.
| |
| 10:53 | so whats the problem with LTSP-5 and gentoo?
| |
| 10:53 | <jammcq> it's just not been integrated yet
| |
| 10:54 | it's quite a bit of work. ltsp-5 builds upon the distro packages, and needs to be carefully integrated into each distro
| |
| 10:54 | <sunru> ok
| |
| 10:56 | <nonsparker> so no one knows about the ltsp-build --kiosk?
| |
| 10:57 | ltsp-build-client --kiosk
| |
| 11:00 | no one?

| |
| 11:14 | [ogra]:: password expiration is not working in gutsy ?
| |
| 11:14 | <ogra_cmp1> sure it is
| |
| 11:14 | <cdealer> [ogra_cmp1]:: isnt just usermod -e DATE user ?
| |
| 11:14 | Guaraldo has quit IRC | |
| 11:15 | mistik1 has joined #ltsp | |
| 11:15 | <ogra_cmp1> cdealer: no idea, sbalneav wrote that part, but he uses it a lot so i'm sure it works
| |
| 11:15 | <cdealer> ok, will ask to him
| |
| 11:17 | <sbalneav> Should work.
| |
| 11:17 | <cdealer> [sbalneav]:: hey... password expiration isnt working on gutsy ? Here after doing a usermod -e EXP_DATE user when trying to login it stays in the Verifying password... plase wait
| |
| 11:18 | <sbalneav> Well, was working for me.
| |
| 11:18 | <cdealer> [sbalneav]:: you do like I did ?
| |
| 11:19 | <sbalneav> No, I use ldap, so usermod doesn't work well, so I have to edit the ldap entry manually.
| |
| 11:19 | I'll check right now.
| |
| 11:19 | Guaraldo has joined #ltsp | |
| 11:19 | <cdealer> ok
| |
| 11:19 | <ogra_cmp1> i think plain usermod -e worked here
| |
| 11:19 | when i tried
| |
| 11:19 | <Guaraldo> sbalneav: Can you help me with an inssue?
| |
| 11:19 | <cdealer> [sbalneav]:: are you using othe box with ldap for authentication? Im thinking about doing something like this here too
| |
| 11:20 | Im thinking about making webmail, logins and other stuffs to authenticate directly from a ldap box ...
| |
| 11:20 | <sbalneav> I have a separate ldap auth server, yes.
| |
| 11:20 | <Guaraldo> sbalneav: If I have the LTSP5 chroot on a server, but connecting on another server, how can I sync the ssh-keys?
| |
| 11:21 | <sbalneav> Have a look at the edubuntu handbook. We've got a section in there on that.
| |
| 11:21 | ltsp-update-sshkeys --export
| |
| 11:23 | <stefan__> hello, i have a question about serverSizing. I know there is a lot in the wiki, and on the mailinglists, but could not find an answer. What king of CPU do i need for 6 Clients working with OpenOffice and two are yousing videoplayer or Youtube? My old Server (P4 2Ghz, 1GB RAM,100 Mb Nics) cant handle youtube videos. Its very choppi even with one Client (533 Mhz, 128 MB Ram).
| |
| 11:23 | <rjune_> Youtube is likely network bandwidth not CPU
| |
| 11:23 | cyberorg has quit IRC | |
| 11:24 | <rjune_> upgrade the NIC to 1Gb and that should help
| |
| 11:24 | <ogra_cmp1> in ltsp5 use LDM_DIRECTX
| |
| 11:24 | that will disable encryption of teh X traffic
| |
| 11:24 | <stefan__> i tried both, ltsp42 and 5, and 4.2 is a lot faster.
| |
| 11:24 | <rjune_> even still, video uses lots of lan
| |
| 11:25 | and he just told you why
| |
| 11:25 | <stefan__> DO Ireally need 1GB Nic for simpoe youtube viedeos?
| |
| 11:25 | yep
| |
| 11:25 | <rjune_> well, lets do the math
| |
| 11:25 | 320 x 240 x 16 x 30
| |
| 11:26 | == 36.8 Mb/s for a 320 x 240 video at 16bit color and 30fps
| |
| 11:26 | there was work on XDamage so that only stuff that changed got updated, but I don't know where it's at
| |
| 11:27 | <joebaker> Hmm... it would make sense to distribute the codec uncompressor to the thin client, wouldn't it?
| |
| 11:27 | <ogra_cmp1> joebaker: half breeded :P
| |
| 11:27 | cyberorg has joined #ltsp | |
| 11:27 | <rjune_> you would have to compress the entire X streem then
| |
| 11:27 | <ogra_cmp1> run FF on the client
| |
| 11:27 | <rjune_> stream
| |
| 11:27 | <stefan__> whats FF?
| |
| 11:27 | <rjune_> local apps are the historic way around it
| |
| 11:27 | FireFox
| |
| 11:28 | <joebaker> No... FFMpeg
| |
| 11:28 | <ogra_cmp1> no, firefox :)
| |
| 11:28 | <joebaker> oh.
| |
| 11:29 | <ogra_cmp1> ideally we'd have the XDamage fix rjune_ mentioned ...
| |
| 11:29 | <sbalneav> cdealer: You might want to check on the thin client, with SCREEN_02=shell, and look at /var/log/ldm.log
| |
| 11:29 | <joebaker> There are problems with running FF locally on the tc. I hope we can figure out how to integrate it with gnome to do this right.
| |
| 11:29 | <stefan__> well.... should be a 1 Gb Nic on Serverside and 100 Mbit Nic for the thinclients enough?
| |
| 11:30 | <cdealer> [sbalneav]:: I will first reinstall, im not sure if my backuped 7.04 files made some messy in the new instalation ... them I will try expire the logins again to see if the problem persists
| |
| 11:30 | <sbalneav> cdealer: Did you rebuild the chroot?
| |
| 11:30 | <joebaker> We need some sort of proxy between gnome apps and gconfd so applications on the local thin client and apps on the Terminal server all talk to the same gconfd daemon.
| |
| 11:31 | <sbalneav> joebaker: That's a big job. Someone from Gnome will have to step up to the plate and offer assistance on that.
| |
| 11:32 | Since gconfd isn't network aware, it's not likely to happen soon, since gconfd's going to need some major work.
| |
| 11:32 | <ogra_cmp1> thats why consolekit exists
| |
| 11:32 | <cdealer> [sbalneav]:: I just backuped the some /;etc files, like password and shadow, I think the proble may be in here... all the ltsp instalation was made all again....
| |
| 11:32 | <rjune_> ogra_cmp1: so xdamage isn't an option yet?
| |
| 11:32 | <ogra_cmp1> rjune_: no idea :)
| |
| 11:33 | seems you followed close than i did :)
| |
| 11:33 | *closer
| |
| 11:33 | <rjune_> stefan__: you should get much better performance from it, have you used anything to track network usage on the server?
| |
| 11:33 | ogra_cmp1: my info is a year old at best, so that's scary
| |
| 11:33 | <stefan__> not yet.... what is the best tool for it?
| |
| 11:33 | <ogra_cmp1> stefan__: also note there is more that makes a network ... its not only NICs
| |
| 11:33 | <rjune_> MRTG + SNMP is easy
| |
| 11:34 | <joebaker> Gconfd uses Orbit (iirc) which is network aware but there doesn't seem to be much documentation on it.
| |
| 11:34 | <rjune_> heh, I did assume your switch supported at least one gigabit port
| |
| 11:34 | <ogra_cmp1> well, just dont use HUB :)
| |
| 11:34 | <rjune_> oh god.
| |
| 11:34 | that's wrong
| |
| 11:34 | a Gb hub?
| |
| 11:34 | * rjune_ shudders | |
| 11:34 | <ogra_cmp1> people do it
| |
| 11:35 | nah, not GB
| |
| 11:35 | <stefan__> i have only a 100 Mbit Switch at the moment
| |
| 11:35 | Guarald1 has joined #ltsp | |
| 11:35 | <rjune_> stefan__: then a gigabit nic won't help
| |
| 11:35 | <stefan__> so will to get one with 1 GB itlink
| |
| 11:35 | Guaraldo has quit IRC | |
| 11:35 | <stefan__> o know ;)
| |
| 11:35 | <ogra_cmp1> but having one HUB in your network can even make the network die if your server is connected via a gigE switch
| |
| 11:35 | <stefan__> -o +i
| |
| 11:35 | <rjune_> ogra_cmp1: I had a support call over the weekend with a customer that paid somebody twice what I make. It was so depressing
| |
| 11:36 | <joebaker> I bet I could hack together some sort of gconfd proxy to make it network transparent.
| |
| 11:36 | <ogra_cmp1> rjune_: time to raise the prices eh ? :)
| |
| 11:36 | <sbalneav> By all means, start hackin :)
| |
| 11:36 | <rjune_> I was pretty close to offering him my services.

| |
| 12:05 | <ogra_cmp1> /etc/ltsp/dhcpd.conf overrides all others
| |

| |
| 12:06 | <ogra_cmp1> nop
| |
| 12:07 | <upro> ogra_cmp1: when I don'T have default /etc/dhcp.conf and do /etc/init.d/dhcp3-server restart it fails (it also fails with /etc/dhcp.conf)

| |

| |
| 12:10 | <ogra_cmp1> no
| |
| 12:10 | <upro> I ran the command... but still fails...

| |
| 13:16 | <upro> maybe it is the external IP of my dsl modem?
| |
| 13:16 | <sbalneav> Don't know.
| |

| |
| 13:20 | <upro> I intend to use it for the ltsp
| |
| 13:20 | wifi connects me to dsl
| |
| 13:21 | <sbalneav> ok, so you haven't set an ip address for he wired interface then, right?
| |
| 13:21 | You'll have to set a static IP address.
| |
| 13:21 | <upro> sbalneav: no, it's all dhcp (from the dsl modem)
| |
| 13:21 | <sbalneav> Something like 192.168.0.254
| |
| 13:21 | cyberorg_ is now known as cyberorg | |
| 13:23 | <upro> sbalneav: a static adress for the server nic?
| |
| 13:23 | <sbalneav> Yes.
| |
| 13:24 | If it's serving terminals, it should have a static address.

| |
| 13:24 | You're a champ!
| |
| 13:25 | sbalneav: if I use 192.168.0.254 as adress, 255.255.255.0 is the subnet, but what will be the gateway?
| |
| 13:26 | <sbalneav> You don't need a gateway. The terminals themselves don't need to talk to anything but the server. Your applications run on the server, and there, you're using the wifi and it's gateway for internet access.
| |
| 13:27 | <upro> sbalneav: ok. Then now I'll try to start my thin client...

| 14:58 | <sbalneav> You'd be better to lower it.

| 15:48 | <sbalneav> Yup. Ubuntu and debian use pulseaudio in LTSP5
| |
| 15:49 | <sgtpepper> I'll try to do it with Fedora 8, or better yet with centos 5
| |
| 15:53 | well I can use the same tarball
| |
| 15:54 | <sbalneav> Well, probably not, there's only source available for ltsp5
| |
| 15:54 | ltsp5 relies on tight integration with the distro
| |
| 15:55 | I beleive Fedora's currently being worked on now, but it's not available yet.

| 16:58 | <bartolomeo80> hello
| |
| 16:58 | i need some help
| |
| 17:00 | i have a thin station and after ten minutes the system stucks and i only can move the mouse
| |
| 17:01 | | |
| 17:01 | <rjune_> Sounds like a modal dialog
| |
| 17:01 | does capslock/numlock work?
| |
| 17:02 | <bartolomeo80> yes
| |
| 17:03 | after a few minutes, the system comes back
| |
| 17:03 | <rjune_> sounds like one of two things
| |
| 17:03 | load on the server, or the modal dialog.
| |
| 17:03 | run top on the server to see what happens to CPU usage

| 17:16 | <bartolomeo80> hello
| |
| 17:17 | i have checked the server running top command
| |
| 17:17 | <rjune_> ko
| |
| 17:17 | <bartolomeo80> and the most of the time the cpu usage is 90% idle
| |
| 17:17 | <rjune_> ok, and what was happening when you experience the lock
| |
| 17:17 | <bartolomeo80> i was running firefox and opera at the same time
| |
| 17:18 | <rjune_> ok, but what happened to CPU usage
| |
| 17:18 | <bartolomeo80> | |
| 17:19 | <rjune_> only other thing I could think of is network lag
| |
| 17:20 | <bartolomeo80> | |
| 17:20 | <rjune_> not sure why this one would.
| |
| 17:20 | maybe you have two systems with the same mac or IP?

| 21:07 | <sbalneav> Evening all
| |
| 21:26 | J45p3r has left #ltsp | |
| 21:28 | <Databastard> Is this a good place to ask about serving a floppy disk image using memdisk?
| |
| 21:35 | <sbalneav> Memdisk?
| |
| 21:36 | <Databastard> part of syslinux
| |
| 21:37 | <sbalneav> Doubt many people would know about that here, but ask your question anyway.
| |
| 21:37 | Someone may know.
| |
| 21:38 | <Databastard> I've also tried booting from a floppy image with "kernel floppy.img" but the PXE client does to multicolored ASCII garbage
| |
| 21:40 | <sbalneav> Well, you'll need the pxe stuff from syslinux to boot from a pxe network card.
| |
| 21:41 | pxe wants a small boot loader to begin with, and the boot loader will load your floppy image from there.
| |
| 21:41 | Maybe if you tell us exactly what it is you're trying to accomplish, we might be able to help you better.
| |
| 21:41 | <Databastard> So, if I'm using Edubuntu, I need to scrap all that and run syslinux?
| |
| 21:41 | Okay
| |
| 21:43 | At work, we currently use about 200 USB floppy drives to run a bootable dos disk to a bunch of terminals. The idea is to serve the floppy image from a server with PXE, tftp, dhcp.
| |
| 21:44 | I used Edubuntu which loads a linux kernal right out of the box
| |
| 21:44 | <sbalneav> right.
| |
| 21:44 | So, what's on this dos disk?
| |
| 21:45 | Etherboot?
| |
| 21:45 | Al-Khouli has joined #ltsp | |
| 21:45 | <Databastard> So I don't want that, I want to automatically load the dos image with diagnostics
| |
| 21:45 | no
| |
| 21:45 | Does that need to be in the floppy image?
| |
| 21:45 | Al-Khouli has quit IRC | |
| 21:47 | <sbalneav> I'm sorry, I'm not understanding. What's on this dos image? Are these thin clients you're booting?
| |
| 21:47 | BGomes has joined #ltsp | |
| 21:50 | <Databastard> It's an image of a floppy disk. The disk is bootable and runs a diagnostic program without user input. The clients have hard drives, but no external drives.
| |
| 21:52 | GiantPickle has quit IRC | |
| 21:55 | <sbalneav> Ah, so this has nothing to do with ltsp per se.
| |
| 21:55 | ok
| |
| 21:55 | <Databastard> all right
| |
| 21:55 | <sbalneav> Sorry, couldn't understand what you were trying to do
| |
| 21:55 | <Databastard> No problem
| |
| 21:56 | <sbalneav> ok, well, you'll definitely need to use the syslinux pxe stuff
| |
| 21:56 | <Databastard> That's what I was afraid of
| |
| 21:56 | Good night
| |
| 21:56 | <sbalneav> Well, hold on.
| |
| 21:56 | you want help or not?
| |
| 21:56 | <Databastard> Sure
| |
| 21:57 | I didn't want to be obtrusive or anything
| |
| 21:57 | <sbalneav> You're not. It's not like the channels overloaded.
| |
| 21:57 | Hold on, I'm looking at this:
| |
| 21:57 | http://www.smop.co.uk/mediawiki/index.php/PXE_booting_floppy_images
| |
| 21:58 | <BGomes> sbalneav: hi, how are u! :)
| |
| 21:59 | <sbalneav> BGomes: I'm fine, yourself?
| |
| 21:59 | Databastard: Looks like that page seems to have some stuff you'll need.
| |
| 21:59 | Most of it will port across nicely to edubuntu. The dhcp server's the same.
| |
| 21:59 | <BGomes> sbalneav: go back to working in ltsp5 on slackware on last week...
| |
| 22:00 | <Databastard> This is where I get confused
| |
| 22:00 | <sbalneav> Databastard: Since you're not using the dhcpd for booting ltsp, what you may want to do is mv /etc/ltsp/dhcpd.conf /etc/ltsp/notinusedhcpd.conf
| |
| 22:00 | <Databastard> When I use kernel memdisk
| |
| 22:01 | <sbalneav> then use their dhcpd.conf they provide in /etc/dhcp3/dhcpd.conf
| |
| 22:01 | <BGomes> sbalneav: we have a progress now.
| |
| 22:01 | <Databastard> When I use "kernel memdisk" the pXE boot halts and says that memdisk kernel not found
| |
| 22:01 | ah
| |
| 22:01 | <sbalneav> BGomes: Ah, that's good news. You're using ldm and localdevices?
| |
| 22:01 | <Databastard> So I need to change the dhcp.conf file
| |
| 22:02 | <sbalneav> They have an example there you can tweak, at that web address I posted.
| |
| 22:02 | Looks like you'll also need to move /var/lib/tftpboot/ltsp out of the way, and set up the syslinux stuff they post there.
| |
| 22:02 | <BGomes> sbalneav: we are makeing initrd.img for compatibli with slackware, localdevices woking fine, but ldm have many paths for working ( it next step)
| |
| 22:03 | <sbalneav> Might need a bit of tweaking, but it looks relatively straightforward.
| |
| 22:03 | <Databastard> okay
| |
| 22:03 | I'll go with that
| |
| 22:03 | thanks
| |
| 22:03 | <sbalneav> sbalneav@phobos:~$ aptitude search syslinux
| |
| 22:03 | p syslinux - Bootloader for Linux/i386 using MS-DOS flo
| |
| 22:03 | Looks like syslinux is available in the package archives.
| |
| 22:03 | The writeup's for Debian, so it'll be fairly close of edubuntu.
| |
| 22:04 | BGomes: Congratulations!
| |
| 22:04 | <Databastard> so I can install it with Synaptic?
| |
| 22:04 | <sbalneav> BGomes: Got a web page for the project?
| |
| 22:04 | Databastard: Yep.
| |
| 22:05 | I guess the real question is: once you've got it working, what are you going to do with 200 usb boot floppies? :)
| |
| 22:06 | <BGomes> sbalneav: now, use the wiki of my bussines, but we are to make the website project, in nexts weeks
| |
| 22:06 | <sbalneav> Sounds awesome!
| |
| 22:06 | <Databastard> Well, most of them will eventually be destroyed by our loaders :P

| |
| 22:56 | anybody there !!
| |
| 22:59 | boog has joined #ltsp | |
| 23:05 | <BGomes> Al-Khouli: what u do it?
| |
| 23:05 | <Al-Khouli> BGomes: sorry , i ddn't get u ??
| |
| 23:06 | <BGomes> Al-Khouli: what u can read about of ltsp5 ?
| |
| 23:07 | <Al-Khouli> BGomes: in fact i need this cz i am going to try a cluster over LTSP-5
| |
| 23:07 | <BGomes> Al-Khouli: what is yout linux dist?
| |
| 23:07 | <Al-Khouli> BGomes: edubuntu
| |
| 23:08 | <BGomes> Al-Khouli: you need read of local apps, you can use cluster of edubuntu normal instalation
| |
| 23:09 | <Al-Khouli> BGomes: i am initially thinking about openmosix
| |
| 23:10 | <BGomes> Al-Khouli: if you can use cluster on edubuntu you can make some step on root-tree of ubuntu of ltsp5
| |
| 23:10 | <Al-Khouli> BGomes: i am not sure where can i start from
| |
| 23:10 | <BGomes> Al-Khouli: read more of edubuntu and openmosix, but openmosix dont woking in kernel 2.6
| |
| 23:11 | <Al-Khouli> BGomes: what shall i go for then ? any other suggestions ?
| |
| 23:12 | <BGomes> Al-Khouli: if you can to make cluster on edubuntu machine, you too to make on ltsp5 root-tree, no have diff of edubuntu and root-tree-ltsp5
| |
| 23:13 | Al-Khouli: use openssi for it
| |
| 23:13 | Al-Khouli: all it's possible on ltsp5
| |
| 23:17 | <Al-Khouli> BGomes: Does this mean that openmosix is obsolete nowadays ?
| |
| 23:18 | <BGomes> BGomes: yes... see on website project..
| |
| 23:28 | go out...
