| |
| 08:53 | <sbalneav> Morning all
| |
| 08:57 | erieslabnx has joined #ltsp | |
| 08:58 | <_UsUrPeR_> hey sbalneav
| |
| 08:58 | !s
| |
| 08:58 | <ltspbot> _UsUrPeR_: "s" is Scotty!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
| |
| 08:58 | <erieslabnx> Is there any simple diagnostic tool for servers? For no apparent reason only 2 of my 10 clients can login, they took almost 5 minutes to do so and I don't know why.
| |
| 08:59 | I don't know what could have changed outside of the new ubuntu updates that were on my screen this morning
| |
| 09:00 | server is running slow as *&^ now too, Firefox taking minutes to respond
| |
| 09:01 | after updates do I need to rebuild the boot image?
| |
| 09:04 | <_UsUrPeR_> erieslabnx: you only need to rebuild an image if you have updated the image's chroot
| |
| 09:04 | i.e. made changes in /opt/ltsp/i386/*\
| |
| 09:04 | err... ignore the last backslash
| |
| 09:04 | <erieslabnx> ok then it must not be that :)
| |
| 09:04 | <_UsUrPeR_> yeah :/
| |
| 09:05 | are you noticing any strange stuff in top/system monitor? What linux derivative are you using?
| |
| 09:05 | <erieslabnx> januty, nothing strange in system monitor, but even system monitor can take minutes to start
| |
| 09:06 | jaunty*
| |
| 09:06 | <_UsUrPeR_> and this slowness is new?
| |
| 09:06 | <erieslabnx> yes today it is new, reboot does nothing to help
| |
| 09:07 | ran fine when I left it on Thursday
| |
| 09:07 | all clients were online
| |
| 09:07 | <_UsUrPeR_> Have you checked your drive capacities to ensure you're not pushing 100% on something?
| |
| 09:07 | I have had that creep up on me before
| |
| 09:08 | ("df -h" in terminal)
| |
| 09:08 | <erieslabnx> I am at about 70% free on drives, 2ghz Athlon with 2GB of RAM
| |
| 09:09 | <_UsUrPeR_> hmm~~~ and your RAM is not being fully used (i.e. swapping)
| |
| 09:09 | <erieslabnx> INSANITY!!! LOL
| |
| 09:09 | ok terminal finally lit
| |
| 09:10 | 15% in use
| |
| 09:10 | <_UsUrPeR_> :/
| |
| 09:10 | getting your clients working seems like the least of your issues compared to your server at this point. At least they still work
| |
| 09:11 | <erieslabnx> what drives me nuts is I can't figure out what could have changed :/
| |
| 09:11 | or more importantly why a reboot doesn't help :P
| |
| 09:12 | <_UsUrPeR_> what type of video card are you running?
| |
| 09:12 | <erieslabnx> Nvidia I think
| |
| 09:12 | yes Nvidia
| |
| 09:13 | GeForce 8200
| |
| 09:13 | <_UsUrPeR_> hmm. you ran top as root to make sure you weren't noticing some crazy process right?
| |
| 09:13 | * _UsUrPeR_ will brb | |
| 09:14 | <erieslabnx> no I just run the system monitor, and gnome-system-monitor is the highest CPU using process
| |
| 09:15 | dorimar has quit IRC | |
| 09:23 | <_UsUrPeR_> erieslabnx: hmm. You're sure the AMD chip isn't kicking in to a over-temp protected mode? I am running out of guesses
| |
| 09:23 | <erieslabnx> no worries, when day is done I will reinstall all :)
| |
| 09:24 | thanks for the efforts
| |
| 09:25 | alkisg has joined #ltsp | |
| 09:30 | <_UsUrPeR_> no problem. Good luck.

| 11:04 | <WhorkMan> good morning everyone :)
| |
| 11:09 | <sbalneav> Morning
| |
| 11:11 | <WhorkMan> hows your day going?
| |
| 11:11 | <Lumiere> !s
| |
| 11:11 | <ltspbot> Lumiere: "s" is Scotty!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
| |
| 11:12 | <Lumiere> hi sbalneav, WhorkMan
| |
| 11:12 | <WhorkMan> Lumiere: good day :)
| |
| 11:12 | <Lumiere> do either of you know of how people fix entropy on larger ltsp installations?
| |
| 11:13 | <WhorkMan> Lumiere: i dont :/
| |
| 11:13 | <sbalneav> We're talking about firefox's random number generator problem here?
| |
| 11:13 | <Lumiere> sbalneav: we're not even getting logged in
| |
| 11:13 | it seems
| |
| 11:14 | but firefox may be eating entropy too
| |
| 11:14 | <sbalneav> Odd. How many workstations?
| |
| 11:14 | <Lumiere> 20-30
| |
| 11:14 | <sbalneav> I have 40 workstations, but never have problem with entropy.
| |
| 11:14 | <Lumiere> ubuntu?
| |
| 11:15 | <sbalneav> However, I don't run the generic kernel, I run the -server kernel.
| |
| 11:15 | yes, hardy.
| |
| 11:15 | <Lumiere> hmm
| |
| 11:15 | <sbalneav> Are you running with the generic kernel?
| |
| 11:15 | <WhorkMan> my ubuntu and gentoo servers dont play nice together :/
| |
| 11:15 | <Lumiere> not sure
| |
| 11:15 | I have to look at it this afternoon
| |
| 11:16 | <sbalneav> balneav@sputnik:~$ uname -a
| |
| 11:16 | Linux sputnik 2.6.24-19-server #1 SMP Wed Aug 20 23:54:28 UTC 2008 i686 GNU/Linux
| |
| 11:16 | -server's the key there.
| |
| 11:17 | <Lumiere> k
| |
| 11:18 | <WhorkMan> hrm. i have a quick question about lts.conf in ltsp5... i assume it is pulled via tftp correct? at what point does it get pulled?
| |
| 11:18 | <ogra_> initramfs
| |
| 11:18 | ogra_ is now known as ogra | |
| 11:19 | <Lumiere> yea... prior to the mountpoint swap from initramfs to nbd/nfs
| |
| 11:19 | <WhorkMan> thats what i was thinking, though i dont see it trying to pull the file at all
| |
| 11:20 | thanks, i am going to go digging around in my images a bit. :)
| |
| 11:21 | <ogra> it determines the tftp path from the filename direcive in the dhsp reply
| |
| 11:21 | *dhcp
| |
| 11:23 | <WhorkMan> ogra: i had read that, everything else tftp related seems to be working ok
| |
| 11:24 | probably doesnt help that the dhcp and tftp server isnt on the same box as the ltsp enviroment. heh
| |
| 11:26 | <ogra> hmm, it might be a problem with next-server not being used
| |
| 11:29 | fotanus has quit IRC | |
| 11:29 | <WhorkMan> i have next-server set to 10.0.0.1, ltsp is setup on 10.0.0.2

| 11:40 | <alkisg1> WhorkMan: (echo "get ${tftpath:-/ltsp/i386}/lts.conf"|tftp ${ROOTSERVER} >/dev/null 2>&1) ==> the LTSP server is considered to be the tftp server as well...

| 12:03 | <WhorkMan> alkisg thanks :)
| |
| 12:04 | <alkisg> Np... it would be easy to patch it if you want, or well put lts.conf in the ltsp server :)
| |
| 12:12 | <erieslabnx> any quick guess off hand as to why the sound will play locally on clients half the time and the other half it plays the sound on the server itself (not playing on the thin client)?
| |
| 12:12 | FarmTown on Facebook has annoying music lol
| |
| 12:17 | rjune_ has joined #ltsp | |
| 12:18 | <vagrantc> erieslabnx: distro and version?
| |
| 12:18 | <erieslabnx> Ubuntu Jaunty
| |
| 12:19 | I can search it, I just figured if it was a common thing someone would know off the top of their head :)
| |
| 12:19 | <vagrantc> erieslabnx: and by half the time, do you mean sometimes login plays on the thin client, and on logging in again, it might end up playing on the server?
| |
| 12:20 | or that any given application might play on the server one time, and without logging out, when started again it plays on the thin client?
| |
| 12:20 | <erieslabnx> yes
| |
| 12:20 | very random
| |
| 12:21 | <vagrantc> erieslabnx: which is it? i described two different scenarios...
| |
| 12:21 | maybe i didn't make it clear enough...
| |
| 12:21 | <erieslabnx> the first
| |
| 12:22 | <vagrantc> ok, so any given login will stick with server or thin client for sound?
| |
| 12:22 | <erieslabnx> correct
| |
| 12:22 | it seems to stick like that, but it seems hit and miss
| |
| 12:22 | like I never know when or why it chooses to do so
| |
| 12:23 | <vagrantc> from the same thin client?
| |
| 12:23 | fotanus has joined #ltsp | |
| 12:23 | <erieslabnx> from more than one but yes it seems to be 2-3 particular machines
| |
| 12:23 | some clients have never done it
| |
| 12:23 | <vagrantc> particular users?
| |
| 12:24 | <erieslabnx> yes
| |
| 12:24 | seems to be just 2 user accounts
| |
| 12:25 | could it be not loading drivers properly?
| |
| 12:25 | <vagrantc> probably some setting stuck into a . file in their home directory...
| |
| 12:25 | or maybe a running daemon that doesn't close on logout
| |
| 12:25 | <erieslabnx> from that assumption in theory would recreating the user account fix it?
| |
| 12:25 | <vagrantc> if you wipe the home directory
| |
| 12:26 | typically the home directory isn't deleted when the account is
| |
| 12:26 | i'm just guessing, though.
| |
| 12:26 | <bieb> vagrantc: are home directories required? I will have our clients authenticating against Active Directory, and the students don't curently have home dirs
| |
| 12:26 | <vagrantc> never seen any problem like that
| |
| 12:27 | bieb: yes
| |
| 12:27 | <erieslabnx> ok :) I will make sure to take note more when it happens in case my memory isn't working right
| |
| 12:27 | <bieb> vagrantc: any recommended or minimum size for the HomeDir?
| |
| 12:27 | <vagrantc> bieb: it's probably not impossible to do without them, but it's likely to lead to tears
| |
| 12:28 | !serversize
| |
| 12:28 | <ltspbot> vagrantc: "serversize" is http://wiki.ltsp.org/twiki/bin/view/Ltsp/ServerSizing
| |
| 12:28 | <vagrantc> bieb: try that ^^
| |
| 12:28 | <bieb> thanks
| |
| 12:29 | <Gadi> bieb: https://help.ubuntu.com/community/UbuntuLTSP/ActiveDirectoryIntegration
| |
| 12:29 | if you are on ubuntu
| |
| 12:30 | <bieb> yeah I will be using Ubuntu 9
| |
| 12:30 | <vagrantc> Gadi: so, i tried NBD+squashfs+aufs, just like ubuntu, and still /media/root/* stuff just plain didn't work.
| |
| 12:30 | Gadi: works for your setups?
| |
| 12:30 | <Gadi> vagrantc: after whats-his-name had issues last week, I did a fresh jaunty install and tried it and it worked fine
| |
| 12:31 | no fancy footwork
| |
| 12:31 | I think your ltspfssd is not compiled with the new patch
| |
| 12:31 | <vagrantc> which new patch?
| |
| 12:31 | something outside of ltspfs-trunk?
| |
| 12:31 | <Gadi> from the troubleshooting I did with him, it didn't have the no auth when connecting from localhost bit
| |
| 12:31 | that is in upstream
| |
| 12:31 | are you compiling from upstream?
| |
| 12:32 | <vagrantc> 0.5.12
| |
| 12:32 | <Gadi> yeah
| |
| 12:32 | but is it compiling fresh?
| |
| 12:32 | <vagrantc> i'm missing my spelling typo, which is the only patch above and beyond that
| |
| 12:32 | Gadi: what do you mean by compiling fresh?
| |
| 12:32 | <Gadi> I mean, is it perhaps not make cleaning
| |
| 12:32 | and using the old ltspfsd binary
| |
| 12:33 | <vagrantc> Gadi: no
| |
| 12:33 | Gadi: i do all my builds in a clean setup
| |
| 12:33 | <Gadi> can you try installing ltspfsd from jaunty?
| |
| 12:33 | or from stgraber's ppa
| |
| 12:33 | <vagrantc> i don't think that'll work, as the udev rules end up in a different place
| |
| 12:33 | * ogra would take a deep look at udev | |
| 12:33 | <vagrantc> i guess i could manually move them
| |
| 12:34 | <Gadi> or at least just grab his ltspfsd binary
| |
| 12:34 | <WhorkMan> hrm. when booting my tc's, it shows IP-Config: eth0 complete with the various info from DHCP, then shows Negotiation: and hangs. any suggestions on what to look for?
| |
| 12:34 | <ogra> ubuntu doesnt use the debian packages anymore since jaunty iirc ... but packages upstream unmodified
| |
| 12:34 | <vagrantc> basically, it mounts /media/root/* if it's there are boot, but doesn't handle device removal or insertion post-boot
| |
| 12:35 | ogra: ubuntu and debian are synced with ltspfs
| |
| 12:35 | <ogra> right but not with udev
| |
| 12:35 | <Gadi> vagrantc: yeah, I dont have that issue on jaunty
| |
| 12:35 | <vagrantc> ogra: there's a rule in debian/rules that puts the udev rules in a different spot, is all.
| |
| 12:35 | <ogra> we have a completely different udev than you
| |
| 12:35 | <vagrantc> ah, got it
| |
| 12:36 | <Gadi> WhorkMan: sounds like Lumiere's issue
| |
| 12:36 | WhorkMan: try: sudo pkill -9 nbd-server
| |
| 12:36 | WhorkMan: and reboot a client
| |
| 12:36 | <ogra> Gadi, so you mean these two should form a club ?
| |
| 12:37 | <Gadi> ogra: yes, and whack you with it :P
| |
| 12:37 | <bieb> vagrantc: I didnt see anything on the per user home dir size. I did appreciate the RAM calculation though.. I was looking for that earlier I was just figuring 100mb per client
| |
| 12:37 | <vagrantc> ogra: what's confusing, is there aren't any different udev rules for local mounts vs. remote ltspfs mounts ... and the local mounts work fine
| |
| 12:37 | <ogra> right, but udevd might behave differently
| |
| 12:38 | <vagrantc> sure ...
| |
| 12:38 | <WhorkMan> Gadi: same thing. :/
| |
| 12:38 | <vagrantc> perplexing, though
| |
| 12:38 | <Gadi> WhorkMan: ps -efw|grep nbd
| |
| 12:38 | <ogra> its the only idea i have
| |
| 12:38 | apart from different kernels indeed
| |
| 12:38 | <Gadi> WhorkMan: are there a ton of nbd processes?
| |
| 12:38 | <WhorkMan> just one
| |
| 12:39 | <Gadi> WhorkMan: do you have any firewalls blocking port 2000?
| |
| 12:39 | <WhorkMan> the LAN side of the router has all ports allowed
| |
| 12:40 | maybe i should try a clean install. heh
| |
| 12:41 | <IBC_jkenney> hello i am trying to setup ltsp (thinclient) to use LDAP for authentication and goup policy is that even possible or am i spinning my wheels
| |
| 12:46 | <WhorkMan> Gadi: i figured out the problem, it was showing one IP (the correct one) on the thinclient and trying to mount another (the wrong one)
| |
| 12:49 | <Gadi> IBC_jkenney: sure - just follow any LDAP howto on the server
| |
| 12:49 | <IBC_jkenney> Gadi am i following the howto on the ldap server then do i have to rebuild the client?
| |
| 12:49 | sorry ldap=ltsp
| |
| 12:50 | the ldap server is all ready running they are seperate VM'S
| |
| 12:50 | <Gadi> IBC_jkenney: no, the thin clients use SSH
| |
| 12:50 | so it is the server's SSH auth that auth's the client
| |
| 12:50 | as long as ssh auths using LDAP on the server, ur good
| |
| 12:51 | <IBC_jkenney> how about group polices for access to certain application's.
| |
| 12:51 | <Gadi> totally different subject
| |
| 12:51 | :)
| |
| 12:51 | you can lock that down with your desktop environment's lockdown tools
| |
| 12:52 | <IBC_jkenney> can you point me in a direction for that subject matter so i can read then come back with questions
| |
| 12:52 | so i'm not wasting anyone's time
| |
| 12:54 | <ltsppbot> "Gadi" pasted "for _UsUrPeR_" (34 lines) at http://pastebot.ltsp.org/404
| |
| 12:55 | <Gadi> IBC_jkenney: https://help.ubuntu.com/community/LDAPClientAuthentication
| |
| 12:55 | if ur on ubuntu
| |
| 12:55 | <_UsUrPeR_> gadi: :D
| |
| 12:55 | <IBC_jkenney> Thanks Gadi
| |
| 12:56 | <_UsUrPeR_> gadi: one question: is it alright not to include video stuff in xorg.conf?
| |
| 12:57 | <Gadi> _UsUrPeR_: I think so - it should take things piece-meal and modify the bits you supply
| |
| 12:57 | <_UsUrPeR_> hmm
| |
| 12:57 | <Gadi> but, I wasn't sure how that applied to input devices
| |
| 12:57 | :)
| |
| 12:57 | so, ur guess is as good as mine
| |
| 12:58 | if you set CONFIGURE_X=True, it will add skeleton bits for the rest

| 13:22 | <_UsUrPeR_> gadi: it has correctly put in a section "inputdevice" with /dev/ttyS0 as the device
| |
| 13:22 | however, no mouse movement :/
| |
| 13:22 | it does look correct though
| |
| 13:22 | driver is with elotouch installed
| |
| 13:22 | is there anything you would like me to pastebin?
| |
| 13:22 | <Gadi> elotouch, not elographics?
| |
| 13:23 | <klausade> vagrantc: fyi: i just created a squeeze chroot on a lenny machine, and ltsp-localapps "just works"! I need to look at homedirs via ldap, and test some more.but, for sure a good start.
| |
| 13:24 | <vagrantc> klausade: yeah!
| |
| 13:24 | <_UsUrPeR_> :3 my bad, elographics it is.
| |
| 13:25 | <vagrantc> klausade: there are some issues with locales (localapps get the same locale as LDM, rather than the user's session), but overall, it works :)
| |
| 13:25 | <Gadi> _UsUrPeR_: can you pastebot the ltsp-xorg.conf?
| |
| 13:25 | <_UsUrPeR_> gadi: np
| |
| 13:26 | <vagrantc> Gadi: so i tried ltspfs local mount stuff again, and this time, it actually registered a CD eject, but not an insertion...
| |
| 13:26 | <klausade> vagrantc: iceweasel+flash running localy is a sure winner, with youtube and the likes.
| |
| 13:26 | <Gadi> vagrantc: can you try a USB device?
| |
| 13:26 | hehe - I love it when they call it iceweasel

| |
| 13:27 | <_UsUrPeR_> gadi: yeah
| |
| 13:27 | <Gadi> _UsUrPeR_: wheres the rest of it?
| |
| 13:27 | <_UsUrPeR_> I can make the changes to your script for a USB device
| |
| 13:27 | ?!?
| |
| 13:27 | * vagrantc rummages around for a physical thin client | |
| 13:28 | <Gadi> the mods I pastebot'd should have a ServerLayout section
| |
| 13:28 | did you update the image?
| |
| 13:28 | <klausade> Gadi: don̈́'t hit me! i just learnt how to spell iceweasle properly.
| |
| 13:28 | <Gadi> klausade: no, its just funny because "firefox" is a real animal name
| |
| 13:28 | it is not a "fire" "fox"
| |
| 13:29 | so, "ice" "weasel" is just all the more ridiculous
| |
| 13:29 | <_UsUrPeR_> it's true. ice and weasels typically are never combined
| |
| 13:30 | gadi: gimme a moment. lemme make sure my lts.conf is setup correctly
| |
| 13:30 | <Gadi> np
| |
| 13:30 | <_UsUrPeR_> was there supposed to be options called in lts.conf for minx and maxx and whatnot, or were those going to be put in by the script
| |
| 13:30 | ?
| |
| 13:33 | <klausade> vagrantc: how do I best controll the sound volume? using pulseaudio(pavucontroll)? or alsamixer/kmix/... running localy?
| |
| 13:34 | johnny has joined #ltsp | |
| 13:34 | <Gadi> _UsUrPeR_: lts.conf
| |
| 13:35 | <_UsUrPeR_> gadi: rgr. just re-read your script
| |
| 13:35 | <Gadi> the driver should have sane defaults
| |

| 13:39 | I don't think you updated the file I pasted
| |
| 13:40 | http://pastebot.ltsp.org/404
| |
| 13:40 | that should replace the: /opt/ltsp/i386/usr/share/ltsp/screen-session.d/XS95-touchscreen file
| |
| 13:40 | and update the image
| |
| 13:40 | <_UsUrPeR_> :O oh. I thought this was another .sh file :)

| |
| 13:42 | <klausade> vagrantc: ok. and now the "ignorant" question. must all my browserplugins be in the chroot? as long as the browser runs as localapp?
| |
| 13:42 | <vagrantc> klausade: yes
| |
| 13:43 | <klausade> vagrantc: i thought so.
| |
| 13:43 | <vagrantc> klausade: well, users can install plugins in their homedirs, but for system-wide, yes, in the chroot

| |
| 13:46 | <knipwim> i wrote most of it
| |
| 13:46 | <akSeya> hum.. nice
| |
| 13:46 | so
| |
| 13:46 | i had some problems
| |
| 13:46 | <Gadi> vagrantc: /me wonders what is so different about the debian environment
| |
| 13:46 | <vagrantc> Gadi: works if booted with the device, and registers device removals (although sometimes veryu slowly) ... but insertion doesn't kick in
| |
| 13:46 | <akSeya> lemme check
| |
| 13:47 | <vagrantc> Gadi: thankfully, it doesn't break the remote mounts like previous incarnations did
| |
| 13:47 | <sbalneav> New version of docs posted. Lots of cleanup, commenting out of "non-ltsp" related info, explanation of the LIKE keyword, more consistent layout, etc.

| 13:48 | <vagrantc> klausade: actually, you can use the ltsp* and ldm* packages from squeeze on lenny, if you want a little more stability.
| |
| 13:48 | <_UsUrPeR_> gadi: there's an "EndSection" on the end of that
| |
| 13:48 | I missed it in my copy-paste
| |
| 13:48 | <vagrantc> Gadi: yeah, it's a mystery ...
| |
| 13:49 | <Gadi> _UsUrPeR_: where's the AlwaysCore option?
| |
| 13:49 | * _UsUrPeR_ shrugs | |
| 13:49 | <_UsUrPeR_> is that something that I am supposed to be specifying in lts.conf?
| |
| 13:50 | <Gadi> no
| |
| 13:50 | it was in the script I pasted
| |
| 13:50 | it should have put it in the xorg.conf file
| |
| 13:50 | weird...
| |
| 13:50 | did you overwrite what I pasted with what you had?
| |
| 13:50 | <_UsUrPeR_> I see alwayscore in the script
| |
| 13:51 | directly below "DeviceName"
| |
| 13:51 | I overwrote it and updated the server yes
| |
| 13:51 | err client image I mean
| |
| 13:51 | pmatulis has quit IRC | |
| 13:51 | <Gadi> somethings weird

| |
| 13:52 | * _UsUrPeR_ copies the lts.conf he's using: | |
| 13:52 | <Gadi> and I uncaps'd it everywhere
| |
| 13:52 | <johnny> knipwim, you wrote waaay too much
| |
| 13:52 | <akSeya> i had 2 problems with ltsp-build-client on gentoo, but I was able to fix it changing somethings on quickstart/profile.qs
| |
| 13:52 | <johnny> we don't need unionfs at all
| |
| 13:52 | it is completely unnecessary
| |
| 13:53 | the only manual modification needed (other than out of chroot setup like tftp, and dhcp) is modifying genkernel to include more nic modules
| |
| 13:53 | Egyptian[Home] has quit IRC | |
| 13:53 | <johnny> knipwim, in fact.. i consider it completely unsupported
| |
| 13:53 | <vagrantc> Gadi: found the issue: XAUTHORITY=$(find /tmp -maxdepth 1 -mindepth 1 -type f -name xauth-$DISPLAY-*)
| |
| 13:54 | Gadi: there's no xauth-* files in /tmp
| |
| 13:54 | <johnny> there is a bit of funionfs-fuse support in genkernel git now.. but union mounts looks to be making traction, so i think i'll stick with tmpfs bindmounts until they occur in a released kernel
| |
| 13:54 | <vagrantc> Gadi: are there on ubuntu?
| |
| 13:54 | <johnny> knipwim, i wish you would have spoken to me before leading people down such a long path
| |
| 13:55 | <Gadi> vagrantc: shouldn't be - and anyway, we shouldn't need XAUTHORITY at all
| |
| 13:55 | Egyptian[Home] has joined #ltsp | |
| 13:55 | <Gadi> you should be able to comment that out
| |
| 13:55 | since connections from localhost are not auth'd
| |
| 13:55 | <vagrantc> do we need DISPLAY then, too?
| |
| 13:55 | sene has joined #ltsp | |
| 13:56 | <akSeya> johnny, knipwim well.. i'm here to help to
| |
| 13:56 | johnny, remember that error I was getting with ltsp-built-client?
| |
| 13:56 | <johnny> yes
| |
| 13:56 | <Gadi> vagrantc: not 100% sure - I forget what ltspfsd or ltspfsmounter complain about

| |
| 13:56 | <johnny> akSeya, we neeed a place to host a chroot targz.. so we don't need peeps tobuild all the time
| |
| 13:56 | <vagrantc> Gadi: and now... i switch back to NFS... :)
| |
| 13:57 | <Gadi> hehe
| |
| 13:57 | _UsUrPeR_: ttyUSB0 is only for a USB-to-serial converter
| |
| 13:57 | <akSeya> I had to add iso-codes on extra_packages
| |
| 13:57 | <Gadi> is that what you are using?
| |
| 13:57 | <akSeya> without it ldm was not building
| |
| 13:58 | and svg to USE flag
| |
| 13:58 | <klausade> vagrantc: yes. my approach is to start with the latest-and-greatest,and from there move over to more stable stuff.
| |
| 13:58 | <akSeya> after that ltsp-build-client was successfull
| |
| 13:59 | <knipwim> reading ...
| |
| 13:59 | <akSeya> now it tells me to append a correct root= boot option
| |
| 14:00 | <knipwim> johnny: did you read my reply in the wiki discussion?
| |
| 14:00 | <vagrantc> klausade: well, localapps, localdev, sound all work with lenny and the latest ltsp*/ldm* packages :)
| |
| 14:01 | klausade: in fact, i can't get sound to work on squeeze
| |
| 14:02 | <_UsUrPeR_> gadi: just changed /dev/ttyUSB0 to /dev/ttyS0. still no changes :/
| |
| 14:02 | <vagrantc> Gadi: appears to be just as broken with it commented out
| |
| 14:02 | <Gadi> _UsUrPeR_: can you add: CONFIGURE_X=True and pastebot ltsp-xorg.conf?
| |
| 14:03 | oh, actually, before that
| |
| 14:03 | <_UsUrPeR_> gadi: yes, but no gurantees the client will boot afterwards :)
| |
| 14:03 | <Gadi> can you paste the Xorg log file from the client?
| |
| 14:03 | and also note, I said: CONFIGURE_X=True NOT CONFIGURE_X_COMMAND
| |
| 14:04 | <_UsUrPeR_> gadi: rgr
| |
| 14:04 | <Gadi> we don't want to use a sh script
| |
| 14:04 | <_UsUrPeR_> :)
| |
| 14:04 | <akSeya> knipwim, johnny, where does the client read the boot options.. like kernel name and etc?
| |
| 14:04 | <Gadi> _UsUrPeR_: we may need to specify the screen in the server layout
| |
| 14:05 | <knipwim> akSeya: at the tftboot
| |
| 14:06 | <akSeya> client does not have grub nor lilo ... it's says it could not find kernel image: linux
| |
| 14:06 | <_UsUrPeR_> gadi: there's no change to ltsp-xorg.log on the client when using CONFIGURE_X = True
| |
| 14:07 | <johnny> akSeya, /var/lib/tftpboot/ltsp/x86/pxelinux.cfg/default
| |
| 14:07 | <knipwim> akSeya: your tft server is like your grub or lilo, networkbased
| |
| 14:09 | <johnny> akSeya, so what fixes did you make to the build?
| |
| 14:09 | knipwim, the real problem we have to solve is genkernel initramfs, but i'm thinkng about switching to dracut
| |
| 14:09 | depending if they can get their own module inclusion stuff in order
| |
| 14:09 | <akSeya> johnny, I added svg to USE flag and iso-codes to extra_packages
| |
| 14:10 | on /etc/ltsp/quickstart/profile.qs

| 14:10 | <ltsppbot> "_UsUrPeR_" pasted "for Gadi" (44 lines) at http://pastebot.ltsp.org/409
| |
| 14:10 | <johnny> hmm.. that shouldn't be in extra_packages
| |
| 14:10 | it should be a dep of the requiring package
| |
| 14:10 | i actually want to avoid using extra_packages except for the ltsp packages themselves
| |
| 14:10 | and let htme handle their own deps :)
| |
| 14:10 | i thought i had somebody commit the fix to ldm to require iso-codes
| |
| 14:11 | at least.. i think ldm is what requires iso-codes
| |
| 14:11 | <knipwim> yes
| |
| 14:11 | <johnny> too bad i can't run the digest :(
| |
| 14:11 | knipwim, do you have a git checkout of the ltsp overlay?
| |
| 14:11 | litlebuda has joined #ltsp | |
| 14:11 | <knipwim> nope
| |
| 14:11 | i thought you had one
| |
| 14:11 | <johnny> can you?
| |
| 14:11 | i do, but no gentoo box to run ebuild digest :)
| |
| 14:12 | <knipwim> o yes
| |
| 14:12 | <johnny> i need somebody to hook me up with a decent vm or something
| |
| 14:12 | <klausade> vagrantc: sound works just fine here in my squeeze chroot. both playback and record.
| |
| 14:12 | <akSeya> johnny, yeap.. it was ldm which required iso-codes
| |
| 14:12 | <johnny> my laptop just can't handle gentoo
| |
| 14:12 | <Gadi> _UsUrPeR_: out of curiosity, there is no /etc/X11/xorg.conf in the chroot, right?
| |
| 14:13 | I mean on the runtime thin client
| |
| 14:13 | only /var/run/ltsp-xorg.conf
| |
| 14:13 | <johnny> i coulda swore i got that committed before
| |
| 14:13 | <alkisg> johnny: virtualbox?
| |
| 14:13 | <johnny> buti will commit the svg useflat
| |
| 14:13 | alkisg, that won't help!
| |
| 14:13 | it's the hardware that can't handle it
| |
| 14:14 | putting a vm on the hardware that isn't good enough won't magically make it be better hardware :)
| |
| 14:14 | <alkisg> Why, gentoo can't be installed as a guest os in vbox?
| |
| 14:14 | <johnny> of course it can
| |
| 14:14 | but the underlying hardware isn't good enough
| |
| 14:14 | <alkisg> Ah, just throw it away then :)
| |
| 14:14 | <johnny> it's my main laptop
| |
| 14:14 | so.. no :)
| |
| 14:14 | <knipwim> get some virtual memory and proc :)
| |
| 14:14 | <johnny> well.. it is actually my only computer atm
| |
| 14:14 | pmatulis has joined #ltsp | |
| 14:14 | <johnny> it's a pentium m 1.5ghz
| |
| 14:15 | <_UsUrPeR_> gadi: correct. I have used etc/X11/xorg_1420.conf (I am using a dlw 1420 workstation)
| |
| 14:15 | litlebuda has quit IRC | |
| 14:15 | <akSeya> johnny, i don't have "default" on that folder.. I have it on /tftpboot/pxelinux.conf
| |
| 14:15 | <johnny> plus.. why throw away hardware that works perfectly well with fedora 11
| |
| 14:15 | <akSeya> but looks like this is not being read
| |
| 14:15 | <johnny> alkisg, that isn't right
| |
| 14:15 | err akSeya that isn't right
| |
| 14:15 | <alkisg> johnny: heh... I gave my celeron 1.6 laptop to my daughter, and got a new one
| |
| 14:16 | <vagrantc> klausade: weird. i've not seen remote soudn working in squeeze as long as i can remember.
| |
| 14:16 | <johnny> sure.. when i can afford it i will
| |
| 14:16 | you need to set your tftp server to look into /var/lib/tftpboot/ltsp/
| |
| 14:16 | <akSeya> if I type a kernel filename that is on /tftpboot/ltsp/x86 it starts to boot (but crashed)
| |
| 14:16 | <Gadi> _UsUrPeR_: and, you are connecting by serial port?
| |
| 14:16 | <johnny> akSeya, we are standardizing on /var/lib/tftpboot, please use that
| |
| 14:17 | <akSeya> hum..
| |
| 14:17 | <vagrantc> Gadi: so, running the whole su ${USER} -c "/usr/sbin/ltspfsmounter ${MOUNTPOINT} $action"
| |
| 14:17 | <akSeya> ok
| |
| 14:17 | <Gadi> _UsUrPeR_: can u paste ur: /var/log/Xorg.*.log
| |
| 14:17 | <johnny> akSeya, the ltsp-update-kernels should be looking there.. iirc
| |
| 14:17 | <vagrantc> Gadi: seems to be where it's failing ... or at least, when i run it manually, i get a few warnings and errors
| |
| 14:17 | <_UsUrPeR_> gadi: correct. serial port. Not using a usb adapter
| |
| 14:17 | <vagrantc> Gadi: but where does the root mounting happen from?
| |
| 14:18 | <akSeya> johnny, it was ltsp-build-client fault.. :D
| |
| 14:18 | <vagrantc> Gadi: "Cannot open X display" and "Error: /tmp/.root-ltspfs/usbdisk-sda1 is not mounted"
| |
| 14:18 | <Gadi> vagrantc: if USER is unset, ltspfsmounter should run as root, and with a connection from localhost, ltspfsd should not require auth
| |
| 14:19 | vagrantc: then, something needs DISPLAY set

| 14:19 | <_UsUrPeR_> gadi: there you go
| |
| 14:20 | <johnny> akSeya, yes.. as i said.. i'm going to tar it up and ask new users to just use the chroot instead of building it off unreliable sources all the time
| |
| 14:20 | <akSeya> hum.. it's going to be interesting
| |
| 14:21 | <vagrantc> Gadi: on device removals, if someone is logged in, it will run as that user rather than as root.

| |
| 14:22 | <vagrantc> Gadi: so you get into the scenario where it is initially mounted as /media/root/cdrom, but if the cdrom is then removed while the user is logged in, it tries to unmount /media/$user/cdrom ...
| |
| 14:23 | <_UsUrPeR_> gadi: will change that out
| |
| 14:23 | <Gadi> vagrantc: true
| |
| 14:23 | <vagrantc> oh hell... OOM errors.
| |
| 14:23 | <Gadi> vagrantc: it seems to be hard to satisfy both local_apps and RDP (other screen scripts)
| |
| 14:24 | all because of lbmount
| |
| 14:24 | <vagrantc> i've mostly been testing with thin clients with 64MB of ram... wonder if i've been getting OOM errors all along
| |
| 14:24 | alkisg has joined #ltsp | |
| 14:24 | <Gadi> perhaps we should make a separate ltspfsmounter script for localhost mounts
| |
| 14:24 | <_UsUrPeR_> gadi: updating image now
| |
| 14:24 | <Gadi> that does not use lbmount
| |
| 14:25 | and that can just mount in /media
| |
| 14:25 | of course, we would still need to handle permissions on the mounted device
| |
| 14:29 | alkisg has quit IRC | |
| 14:29 | <Gadi> honestly, for local apps, the easiest thing is to create a symlink on login to the server's /media/$USER dir in the user's home directory

| |
| 14:30 | <vagrantc> how does a symlink work across computers, then?
| |
| 14:30 | <Gadi> the symlink should lead the local app to the remote /media
| |
| 14:30 | in sshfs
| |
| 14:30 | <vagrantc> ah.
| |
| 14:31 | <Gadi> then, we can handle RDP+localdev solely
| |
| 14:31 | with the local ltspfsmounter
| |
| 14:31 | <vagrantc> actually, it seems like we need two events...
| |
| 14:32 | i mean, a minor tweak to the current code would be to always run as root, and sometimes run as the user.

| 14:33 | :)
| |
| 14:33 | <_UsUrPeR_> Gadi: which line?
| |
| 14:34 | * _UsUrPeR_ tries to read closely | |
| 14:34 | <Gadi> line 2
| |
| 14:35 | vagrantc: right - its the sometimes thats tricky
| |
| 14:35 | <_UsUrPeR_> :D
| |
| 14:35 | <akSeya> johnny, now I'm not able to start tftp :/
| |
| 14:35 | <_UsUrPeR_> Gadi: what /dev/ should I be using if I want to try USB?
| |
| 14:35 | <akSeya> permissions maybe?
| |
| 14:35 | spectra has joined #ltsp | |
| 14:37 | <Gadi> _UsUrPeR_: not sure
| |
| 14:37 | _UsUrPeR_: it would be one of the /dev/input/event*
| |
| 14:37 | I guess
| |
| 14:37 | <_UsUrPeR_> gadi: ahh :/
| |
| 14:37 | <Gadi> but, get serial going first
| |
| 14:37 | ;)
| |
| 14:37 | <knipwim> akSeya: the tftp server is started?
| |
| 14:38 | <akSeya> no.. I'm trying to find it's log to see whats going on

| |
| 14:40 | <Gadi> _UsUrPeR_: it seems to be missing something still
| |
| 14:40 | <_UsUrPeR_> gadi: same. no results on serial
| |
| 14:41 | <Gadi> duh
| |
| 14:41 | oh no
| |
| 14:41 | wait
| |
| 14:41 | hmm...
| |
| 14:41 | <_UsUrPeR_> did you still want CONFIGURE_X = True on?
| |
| 14:43 | <Gadi> you can try with it off
| |
| 14:43 | I am just wondering why the write_screen 0 >> $XCONF didn't do anything
| |
| 14:47 | <bieb> Gadi: Do you know if these instructions should still work with ubuntu 9?? https://help.ubuntu.com/community/UbuntuLTSP/LTSPWindowsDHCP
| |
| 14:49 | <Gadi> bieb: you need to add an nbdserver kernel parameter to the pexlinux.cfg/default file, as well
| |
| 14:49 | otherwise, the OS will most likely not find the nbd server
| |
| 14:50 | bieb: sorry - "nbdroot" not "nbdserver"
| |
| 14:51 | <bieb> ok.. looking for ndb root docs
| |
| 14:52 | <johnny> ldm now is updated akSeya and knipwim
| |
| 14:53 | <Gadi> bieb: just add: nbdroot=<LTSPserverIP>:2000
| |
| 14:53 | <bieb> ok
| |
| 14:53 | <Gadi> after "quiet" in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
| |
| 14:54 | and if you change the IP of the LTSP server, update it
| |
| 14:54 | <johnny> also added the svg flag
| |
| 14:54 | <bieb> gotcha
| |
| 14:55 | and nothing needs to be done for nbd root swap right?
| |
| 14:56 | <Gadi> you may need: nbdswap=<LTSPserverIP>:9572
| |
| 14:56 | as well
| |
| 14:56 | <vagrantc> Gadi: ok, so, it definitely needs XAUTHORITY...
| |
| 14:56 | <Gadi> for nbdswap to work correctly
| |
| 14:56 | <vagrantc> Gadi: it also needs to always needs to process /media/root ...
| |
| 14:57 | Gadi: can't get it to do /media/$user locallly, though.
| |
| 14:57 | <Gadi> vagrantc: there is an xauth thing for non-ldm sessions in xinitrc.d
| |
| 14:57 | <bieb> Gadi: so whether it needs either of the NBD's is trial and error?
| |
| 14:57 | <Gadi> I forget where it places it
| |
| 14:57 | bieb: no, nbdroot is for the rootfs, nbdswap is for swap over nbd
| |
| 14:57 | use both
| |
| 14:58 | personally, I don't use swap
| |
| 14:58 | <bieb> ok..
| |
| 14:58 | <Gadi> so, I never care to do the second
| |
| 14:58 | :)
| |
| 14:58 | <bieb> :)
| |
| 14:58 | <vagrantc> Gadi: yes, but that only handles delayed-mount stuff, not udev insertion/removal.
| |
| 14:59 | Gadi: if the udev rules are working properly, the delayed mount stuff shouldn't be needed
| |
| 14:59 | Gadi: for /media/root/*
| |
| 14:59 | <Gadi> vagrantc: right, but put back that XAUTHORITY line we had, and s/tmp/\/var\/run/
| |
| 14:59 | <vagrantc> Gadi: yes, that's what i did (although the syntax keeps changing...
| |
| 15:00 | <alkisg> bieb: where's your tftp server?
| |
| 15:00 | <vagrantc> Gadi: i still can't get it to work for $USER, though.
| |
| 15:00 | pmatulis has quit IRC | |
| 15:00 | <bieb> it will be a linux server in the rack..
| |
| 15:00 | <_UsUrPeR_> gadi: FYI "cat /dev/ttyS0" does output stuff
| |
| 15:00 | <Gadi> vagrantc: but does root work better
| |
| 15:00 | <_UsUrPeR_> so the connection between monitor and client does work
| |
| 15:01 | <Gadi> _UsUrPeR_: did you add the ">> $XCONF" to the write_screen line?
| |
| 15:01 | <alkisg> bieb: ah, ok, then I don't think nbdroot is needed at all...
| |
| 15:01 | <bieb> Gadi: we are running AD and the DHCP server is a windows box. That's why I was asking about the https://help.ubuntu.com/community/UbuntuLTSP/LTSPWindowsDHCP doc
| |
| 15:02 | <_UsUrPeR_> Gadi: yeah, just copy-pasted your last creation in. the results showed no changes though :/
| |
| 15:02 | <vagrantc> Gadi: yes, /media/root is working great for me now.
| |
| 15:02 | <Gadi> vagrantc: ah, thats good
| |
| 15:02 | <bieb> the LTSp server is currently sitting on my desk. I have to make a hardware change from the original configuration.. then Ubuntu will be installed and then inserted in the rack

| |
| 15:25 | I do the changes, save it, restart xinetd .. but changes does not take effect
| |
| 15:25 | I searched for pxelinux.cfg/default on other folders.. there is no other...
| |
| 15:27 | <vagrantc> bieb: in what context?
| |
| 15:29 | <bieb> vagrantc: context of how many thin clients are you runnning on your ltsp server.. is it a lab? or do you have them rolled out to people's desks?
| |
| 15:30 | <vagrantc> bieb: i have many ltsp servers, and most of them are fragmented into different pieces of ltsp server (i.e. nfs+tftp on one, dhcp on another, applications on several) ..
| |
| 15:31 | bieb: some lab, some desks.
| |
| 15:31 | and of course, development, which is usually virtual thin clients on my laptop, or occasionally an external thin client
| |
| 15:32 | bieb: at freegeek, we've got probably 15-25 thin clients, and about 3-4 application servers.

| 15:35 | <bieb> vagrantc: I see.. thats a pretty big split

| 15:35 | and how lazy they are at cleaning up old junk
| |
| 15:36 | <ogra_> junk ? where ?
| |
| 15:36 | * ogra_ grabs the sweeper | |
| 15:36 | <Lns> I hear the linux defrag utility automatically cleans up stuff you don't use. I heard a microsoft employee who wrote the "disk cleanup utility" actually wrote it
| |
| 15:37 | <ogra_> bah, just use ext4
| |
| 15:37 | <johnny> akSeya, huh.. what filename ? what you just wrote wasn't right
| |
| 15:37 | * vagrantc wonders what count's as "don't use" | |
| 15:37 | <_UsUrPeR_> Lns: the real kicker: does it warn you if you have not used a desktop icon in a while?
| |
| 15:37 | <akSeya> johnny, pxelinux.cfg/default
| |
| 15:37 | <vagrantc> frag defrag.

| |
| 15:37 | <bieb> vagrantc: thanks... I am trying to determine the hard drive size for the server (OS and Apps) and then a separate /usr drive for home Dirs
| |
| 15:37 | <ogra_> heh
| |
| 15:38 | <akSeya> johnny, but I find out that it's loading pxelinux.0 instead
| |
| 15:38 | <Lns> bieb: /home for users
| |
| 15:38 | <_UsUrPeR_> ogra/lns/anyone else. Gadi and I have been working on touchscreen stuff for 9.04
| |
| 15:38 | <ogra_> cool
| |
| 15:38 | <bieb> Lns: your right.. my bad.. reading the wrong stuff as I am typing here.. :D
| |
| 15:38 | <johnny> akSeya, it loads pxelinux.0 and then the config file
| |
| 15:39 | <_UsUrPeR_> and it's gotten sort-of-almost there
| |
| 15:39 | <bieb> damn multi tasking
| |
| 15:39 | <Lns> _UsUrPeR_: nice =)
| |
| 15:39 | <_UsUrPeR_> but it's not quite there :(
| |
| 15:39 | <akSeya> johnny, hum.. but it is ignoring the config file :(
| |
| 15:39 | <_UsUrPeR_> and it's driving me insane
| |
| 15:39 | <ogra_> _UsUrPeR_, note that the touchscreen handling will change a lot in the near future
| |
| 15:39 | <johnny> are you sure?
| |
| 15:39 | or is the config file empty?
| |
| 15:39 | <_UsUrPeR_> ogra_: not what I wanted to hear ;)
| |
| 15:39 | <ogra_> well, thats why i didnt touch it in jaunty
| |
| 15:40 | <_UsUrPeR_> yeah :P
| |
| 15:40 | <ogra_> i wanted to give xorg and the kernel time to settle
| |
| 15:40 | <johnny> akSeya, if i had a gentoo box available, i'd be able to fix some of the issues like automatically symlinking pxelinux.0 and writing a base config file
| |
| 15:40 | <_UsUrPeR_> we're just trying to use the X_TOUCH_<command> stuff
| |
| 15:40 | <ogra_> in karmic the plan is to add all usb touchscreens to the kernel driver
| |
| 15:40 | <johnny> mmm.. food
| |
| 15:40 | <_UsUrPeR_> man, that would be great
| |
| 15:41 | <ogra_> if thats done you should be able to easily configure them at runtime
| |
| 15:41 | <_UsUrPeR_> the problem I am having right now: I can see in /var/run/ltsp-xorg.conf that everything is inserted in the xorg.conf
| |
| 15:41 | <ogra_> though the ltsp solution probably takes until karmic+1
| |
| 15:41 | <_UsUrPeR_> yet nothing is showing up in Xorg.7.log
| |
| 15:41 | <ogra_> right
| |
| 15:41 | use hal instead
| |
| 15:41 | <_UsUrPeR_> however, if I cat /dev/ttyS0, I will get output from the monitor
| |
| 15:41 | <ogra_> i gave Gadi the right pointers
| |
| 15:42 | oh, its a serial touchscreen ?
| |
| 15:42 | thats very tricky
| |
| 15:42 | <_UsUrPeR_> it's got both. Gadi is saying serial will be easier for the moment
| |
| 15:42 | and USB later
| |
| 15:42 | <ogra_> serial will always need configs
| |
| 15:42 | <_UsUrPeR_> which is fine. We have the configs in order
| |
| 15:42 | <ogra_> right
| |
| 15:42 | <_UsUrPeR_> in the lts.conf
| |
| 15:42 | <ogra_> but i cant help you much
| |
| 15:42 | <_UsUrPeR_> ok
| |
| 15:43 | <ogra_> serial is something you cant probe ...
| |
| 15:43 | i usually work on automation
| |
| 15:43 | <_UsUrPeR_> well if you ever want to start testing out USB on an elotouch with ltsp, let me know :)
| |
| 15:43 | <ogra_> if on a serial port your config doesnt work, it doesnt work
| |
| 15:44 | no chance to fix it if you dont know the right config parameters
| |
| 15:44 | <_UsUrPeR_> (FYI: right now, it is detected properly, but the mouse input is @ 800x600, and it's upside-down)
| |
| 15:46 | ^^ Referring to USB input
| |
| 15:46 | <ogra_> right, as i said ... know the right config and you are golden ... if not ... feel the serial pain
| |
| 15:46 | oh
| |
| 15:46 | well, there should be a swapxy setting or so
| |
| 15:46 | <_UsUrPeR_> according to etyack, I have the exact minX, maxX, minY, maxY settings. He has told me he's gotten it to work in ltsp 4.2
| |
| 15:47 | <ogra_> right, but the driver might need s swap command
| |
| 15:47 | does it use a special kernel module ?
| |
| 15:47 | if so you can usually change direction with a module parameter
| |
| 15:48 | <_UsUrPeR_> nothing that's not pre-installed...
| |
| 15:48 | how do I find out what module it's using?
| |
| 15:48 | <ogra_> well, lsmod on a client and look for suspicious modules
| |
| 15:50 | * vagrantc is starting to suspect "su" is the culprit with local ltspfsmounter | |
| 15:50 | <ogra_> su ?!?
| |
| 15:51 | where the heck is that used ?
| |
| 15:53 | <vagrantc> su ${USER} "/usr/sbin/ltspfsmounter ...
| |
| 15:53 | <ogra_> hrm
| |
| 15:53 | <vagrantc> both for delayed mounter and in the udev scripts
| |
| 15:53 | to support localapps with ltspfs devices
| |
| 15:54 | <ogra_> thats not my code
| |
| 15:54 | <vagrantc> yes, it's not really my code either
| |
| 15:54 | * vagrantc cringes | |
| 15:54 | <ogra_> where would it get ${USER} ?
| |
| 15:54 | <vagrantc> i've made some edits to it
| |
| 15:54 | ogra_: it is the epitome of hack: grepping /proc/mounts for an sshfs mount
| |
| 15:55 | <ogra_> ugh
| |
| 15:55 | * ogra_ is shocked | |
| 15:55 | * ogra_ grabs the sweeper | |
| 15:55 | <ogra_> :)
| |
| 15:55 | <vagrantc> ok, so, now i seee ... fusermount: Permission denied
| |
| 15:56 | <_UsUrPeR_> ogra_: it looks like it loads joydev
| |
| 15:56 | when the usb screen is plugged in
| |
| 15:56 | joydev = module
| |
| 15:56 | <ogra_> hrm
| |
| 15:56 | yeah
| |
| 15:56 | likely wrong
| |
| 15:56 | <vagrantc> user is in fuse group, file looks like fuse group, /dev/fuse has writeable group permissions on fuse ...
| |
| 15:56 | <ogra_> i guess thats something usbtouchscreen will fix
| |
| 15:56 | <vagrantc> what's fusermount got to complain about?
| |
| 15:57 | <ogra_> is user in fuse group locally ?
| |
| 15:57 | or only on the server
| |
| 15:57 | fusewrmount is executed setgid
| |
| 15:57 | at least it was like that until recently
| |
| 15:58 | i think it was just dropped
| |
| 16:00 | * ogra_ grins reading the debian mono stuff | |
| 16:00 | agike_ has quit IRC | |
| 16:01 | <vagrantc> ogra_: yeah, the user is in the fuse group locally...
| |
| 16:01 | fusermount is still setgid here.
| |
| 16:02 | <ogra_> gid might not match what you get from the server though
| |
| 16:02 | <vagrantc> er, setuid, apparently.
| |
| 16:02 | gid is the same.
| |
| 16:02 | <akSeya> knipwim, i was able to fix the pxelinux problem.. now I'm getting mount: RPC: Unable to Send; errno = Network is unreachable !! NFS Mounting failed. Is the pash correct ... I took another computer on the network and I was able to mount the NFS normally
| |
| 16:03 | <vagrantc> well, this baffles my mind.
| |
| 16:05 | * vagrantc chmod +x fusermount | |

| |
| 16:41 | depending on the version

| |
| 16:44 | <Gadi> vagrantc: hmm... do tell
| |
| 16:44 | <akSeya> johnny, so, I'll need to add all network cards my lan has on modules_load.. right?
| |
| 16:45 | <vagrantc> Gadi: for some reason, even though the user is locally in the fuse group, and fusermount is executable by the fuse group, it still refuses to let the user run fusermount ... adding it to be world-executable, and it works
| |
| 16:45 | Gadi: though it doesn't unmount properly.
| |
| 16:46 | although the commits i just made were required to get that much...

| 16:48 | <vagrantc> Gadi: *seemed* to work with nbd+squashfs+aufs now that i got that other code updated... but i'm just now double-checking for sure.
| |
| 16:48 | <Gadi> vagrantc: umount as well as mount?
| |
| 16:49 | <vagrantc> Gadi: maybe different GIDs on the server cause problems for NFS somehow ... though i don't understand why, as locally it uses the appropriate gid.
| |
| 16:49 | sindfil has joined #ltsp | |
| 16:49 | <vagrantc> Gadi: umount doesn't appear to work ... my guess is /etc/passwd and freinds get reset too early?
| |
| 16:49 | <Gadi> if you chown it to the server's gid does it work? :P
| |
| 16:50 | <vagrantc> that would seem all kinds of wrong...
| |
| 16:50 | but worth trying

| |
| 16:52 | <vagrantc> Gadi: that might be too kind
| |
| 16:55 | well, that test went all kinds of wonky.
| |
| 16:55 | now remote mounts didn't kick off.
| |
| 16:58 | <akSeya> johnny, ok.. already have the correct module.. it is loading.. but still not able to mount nfs

| 17:04 | <akSeya> johnny, on a normal machine i can mount it with no problems...
| |
| 17:05 | gonna try on another NIC
| |
| 17:10 | hum.. on some machines I get the same error, on others (when I use a floppy) I get "segment [a number]:[other number] does not fit in any memory region"

| 17:47 | <akSeya> johnny.. knipwim ... I guess I'll stick with ltsp-4.2 for now.. anyway, thanks a lot for your help and attention
| |
| 17:48 | <johnny> ltsp 4.2 has security holes
| |
| 17:49 | and is not updated
| |
| 17:49 | i don't know why nfs is not working,
| |
| 17:49 | you haven't even shown me what your pxelinux.cfg/default looks like
| |
| 17:49 | perhaps it is not correct
| |
| 17:49 | <akSeya> hum..
| |
| 17:50 | one second
| |
| 17:50 | <johnny> akSeya, the real problem here is that i just don't have a gentoo machine around :(
| |
| 17:51 | <akSeya> well.. i'm able to boot now.. it loads the kernel, the nic modules, but is unable to mount root
| |
| 17:51 | also says that network is unreachable
| |
| 17:52 | johnny, http://pastebin.com/m70919c2b
| |
| 18:01 | johnny, my problem is that I have only tomorrow to get it working
| |
| 18:04 | <johnny> that's not what i had in my config
| |
| 18:04 | mine was somewhat differently
| |
| 18:04 | i wonder if i still even have it :(
| |
| 18:06 | bobby_C has quit IRC | |
| 18:08 | <johnny> dberkholz, are you here?
| |
| 18:18 | <akSeya> johnny, I have good news
| |
| 18:19 | I added debug to the append line, an ifconfig shows me only lo
| |
| 18:19 | then I did ifconfig eth0 10.0.0.250 up
| |
| 18:19 | <johnny> is your nic module actually loaded?
| |
| 18:19 | oh.. so it is
| |
| 18:19 | <akSeya> exit the console
| |
| 18:19 | and it loaded
| |
| 18:19 | <johnny> ok so.. that means it's not getting dhcp
| |
| 18:19 | are you sure your dhcp server is loading then?
| |
| 18:19 | <akSeya> hum...
| |
| 18:20 | <johnny> well i guess it must if you used pxe
| |
| 18:20 | <akSeya> yeah...
| |
| 18:20 | hum.. i have and idea.. one second..
| |
| 18:21 | huum
| |
| 18:21 | looks like ltsp-build-client does not changed /etc/conf.d/net
| |
| 18:21 | <johnny> are you gonna be around for a little while ? because i must travel 20 minutes awa
| |
| 18:21 | but then will be back
| |
| 18:23 | <akSeya> hum.. i'll wait
| |
| 18:23 | ;)
| |
| 18:23 | <vagrantc> Gadi: ok, with my last ltspfs patches, it works fine with nbd+ext2 and nbd+squashfs ... so the bug seems to have something to do with the way NFS handled GIDs.
| |
| 18:23 | Gadi: and group-executable files...
| |
| 18:25 | <akSeya> johnny, I added config_eth0=( "noop" ) to /etc/conf.d/net on the chroot
| |
| 18:25 | lets see if it works :P
| |
| 18:25 | nope
| |
| 18:27 | <johnny> you don't need to add that , i didn't
| |
| 18:27 | ok bbiaf
| |
| 18:27 | johnny has left #ltsp | |
| 18:30 | <Lns> bbiaf = be back, i am farting
| |

| |
| 19:10 | <johnny> akSeya, i think your default pxe file isn't correct
| |
| 19:10 | and now i just remember where it is .. but i am not near it now
| |
| 19:11 | <akSeya> yeah.. i think something is missing there.. so the eth0 does not activate

| |
| 22:38 | <vagrantc> yay. i done gone figured out what was borked with ltspfs and local mounting on debian
| |
| 22:38 | <jammcq> Scotty !!!!!!!!!!!!!!!!!!!!!!!!!!
| |
| 22:38 | vagrantc!!!!!!!!!!!!!!!!!!!!!
| |
| 22:38 | <sbalneav> Hey jammcq
| |
| 22:38 | <vagrantc> the delayed mounter hooks were running when the user wasn't in /etc/passwd
| |
| 22:38 | <jammcq> how's things going?
| |
| 22:38 | <sbalneav> vagrantc: What was causing the problem?
| |
| 22:38 | <vagrantc> jammcq, sbalneav: how was brazil?
| |
| 22:38 | <jammcq> twas great
| |
| 22:38 | <sbalneav> Excellent.
| |
| 22:39 | vagrantc: Got any good tutorials on how to i18n docbook documents? We have people who want to translate the docs into spanish and portugese
| |
| 22:47 | <vagrantc> sbalneav: alas, not much.
| |
| 22:48 | sbalneav: maybe po4a ?
| |
| 22:49 | the other ltspfs local mounting problem is that when using NFS, even if the client says it's group fuse, if the server has a different GID for the fuse group, that somehow still messes things up. even though the client thinks it's the fuse group ... at least for purposes of group-executability ... it refused to run fusermount, essentially.
| |
| 22:50 | <sbalneav> nfs gid mapping goo needed?
| |
| 22:50 | <vagrantc> perhaps. but i don't really understand why ... as the NFS server should just be serving the the numeric ID, and the client thinks it's fuse. and it's running on the client ... so i don't get why it's borked.
| |
| 22:52 | but it is.
| |
| 22:53 | <sbalneav> is the fuse gid different on the server and the client?
| |
| 22:53 | <vagrantc> yes.
| |
| 22:53 | in this case, fuse is 107 on the server, and 106 on the thin-client/chroot.
| |
| 22:54 | the file is gid 106.
| |
| 22:59 | works fine using NBD with ext2 or squashfs.
| |
| 23:07 | <sbalneav> yeah, with nfs, you HAVE to have gid/uid's consistent between client and server
| |
| 23:07 | or bad mojo happens.
| |
| 23:08 | <vagrantc> it just seems inexplicable why there is even a problem.
| |
| 23:08 | if it was just sticking with the GIDs and not using the group NAMEs, everything would be fine.
| |
| 23:09 | somehow it's actually using the group names or something
| |
| 23:11 | this local ltspfs mounting requires so many ugly hacks ... we really need to re-think ltspfs a little for localapps and such.
| |
| 23:12 | <sbalneav> ? Aren't we using sshfs for localapps?
| |
| 23:13 | <vagrantc> sbalneav: for the /media mounts, we're using ltspfs locally.
| |
| 23:13 | sbalneav: otherwise that's a lot of round-trips to get a localapp to talk to the local media... but gah. it's a mess.
