| 06:08 | <Joe90> hi there, quick question - default X manager on ltsp5 (gutsy) - GDM?
| |
| 06:09 | I want to put an auto login line in ltsconf. i.e GDM user= etc
| |
| 06:09 | vagrantc has joined #ltsp | |
| 06:10 | <vagrantc> otavio: so, there were 3 lintian errors from your build that didn't happen on mine.
| |
| 06:10 | otavio: ltsp build, that is. the two i don't understand are the .po errors
| |
| 06:14 | !localdev
| |
| 06:14 | <ltspbot> vagrantc: "localdev" is (#1) Information regarding using pluggable devices and cdroms with LTSP can be found at http://wiki.ltsp.org/twiki/bin/view/Ltsp/LTSP-42-LocalDev, or (#2) for ubuntu: https://wiki.ubuntu.com/EnableLTSP5LocalDevices, or (#3) for debian-edu: http://wiki.debian.org/DebianEdu/HowTo/LocalDeviceLtspfs, or (#4) http://wiki.ubuntu.com/DebugLocalDev
| |
| 06:15 | <ogra> vagrantc, !
| |
| 06:15 | happy 2008
| |
| 06:15 | <vagrantc> ogra: same to you
| |
| 06:16 | ogra: i can't sleep... brain just started thinking about ltspfs :)
| |
| 06:16 | <ogra> heh
| |
| 06:16 | just grab my hal stuff and finish it :P
| |
| 06:16 | <vagrantc> might be out of my league
| |
| 06:16 | where is your hal stuff?
| |
| 06:17 | <ogra> we need a *lot* of changes anyway, nothing in newer gnome or kde releases will work without policykit and consolekit
| |
| 06:17 | which makes everythig harder for us :(
| |
| 06:17 | <vagrantc> indeed
| |
| 06:17 | especially those who want it to be feasible for a backport... and other distros which may or may not implement all this new stuff
| |
| 06:18 | that's why the simple mounting approach is attractive to me
| |
| 06:18 | though i finally hit a wall with the direct mounting to /media/USERNAME ...
| |
| 06:18 | <ogra> all distros *have* to use it
| |
| 06:18 | as long as they use hal
| |
| 06:19 | which means all gnome/kde desktops at least
| |
| 06:19 | <vagrantc> only way to make /media/USERNAME writeable and not actually be on the same filesystem is to mount something there... which causes an icon to show up in nautilus
| |
| 06:19 | <ogra> nothing in gnome or kde will work without approval through one of the kits
| |
| 06:20 | ldm will be the hardest part though
| |
| 06:20 | <vagrantc> yes, but older versions of gnome or kde don't use it, and i would hate to make it impossible to support those
| |
| 06:21 | <ogra> hrmpf ...
| |
| 06:21 | why does sed -i not replace tabs properly :/
| |
| 06:21 | * ogra just notices that XSERVER doesnt work anymore | |
| 06:21 | <vagrantc> what's your sed?
| |
| 06:21 | <ogra> the default one we use in the image
| |
| 06:22 | <vagrantc> the x configuration
| |
| 06:22 | er, i meant "sed line"
| |
| 06:22 | hrm. maybe i'm not really awake
| |
| 06:22 | <ogra> if [ -n "$XSERVER" ] && [ "$XSERVER" != "auto" ]; then
| |
| 06:22 | SERVERLINE="Driver\t\"$XSERVER\""
| |
| 06:22 | sed -i /'Section "Device"'/,/'EndSection'/s/'Driver.*'/$SERVERLINE/g $INPUT_FILE
| |
| 06:22 | <otavio> vagrantc: strange
| |
| 06:22 | vagrantc: have you used up to date sid for building?
| |
| 06:22 | <ogra> the \t isnt parsed as tab
| |
| 06:23 | <vagrantc> otavio: it was updated within a day of when you uploaded
| |
| 06:23 | <otavio> vagrantc: it's strange. Wants me to do another build/upload?
| |
| 06:23 | vagrantc: I've build it in amd64 arch
| |
| 06:24 | <vagrantc> otavio: well, i've got some other changes first.
| |
| 06:24 | otavio: ah, my builds were i386 ...
| |
| 06:24 | otavio: i think the script not executable error was because the executable bit isn't represented in the .diff.gz
| |
| 06:25 | otavio: i don't think any of them are urgent enough to upload before it hits testing
| |
| 06:26 | otavio: which should only be a couple days
| |
| 06:26 | <otavio> vagrantc: ok
| |
| 06:27 | <vagrantc> ogra: any objection to moving the ldm rc.d scripts related to ltspfs into ltspfsd ?
| |
| 06:27 | <ogra> nope
| |
| 06:27 | and i think we had that dscussion already :)
| |
| 06:28 | <vagrantc> yeah...
| |
| 06:28 | just wanted to check before i started making commits
| |
| 06:28 | <ogra> i hope scott returns soon
| |
| 06:28 | <vagrantc> been vacationing in a cabin or something, i hear
| |
| 06:29 | <ogra> tere is so much ldm and ltspfs bugs we need him for (at least i dont see the time on my schedule to work into all that code atm)
| |
| 06:29 | yeah, he bought that cottage with a lot of property around it
| |
| 06:30 | <vagrantc> yeah, ldm needs some work and is largely over my head
| |
| 06:31 | <ogra> not over mine, but i need a certain amount of time ot understand the new stuff
| |
| 06:31 | and classmate keeps me busy this release
| |
| 06:32 | i just started ltsp tests with the -generic image ...
| |
| 06:32 | thats cross arch, so we wont need separate amd64 setups anymore :)
| |
| 06:32 | i was always suspecting the missing 486 instruction set would break the booting ... or make it slow or so ...
| |
| 06:33 | but apparently it even runs on my old 300MHz cyrix chip here
| |
| 06:34 | <vagrantc> hm.
| |
| 06:35 | ogra: cross-arch, as in a single environment will have some i386 and some amd64 binaries?
| |
| 06:35 | and it'll use whichever are appropriate?
| |
| 06:36 | <ogra> no as in amd64 capable kernel with x86 binaries by default
| |
| 06:36 | the ubuntu -generic kernel runs fine on both arches
| |
| 06:37 | binaries are all x86 but run onder a kernel that actually boots on amd64
| |
| 06:37 | <vagrantc> ah
| |
| 06:37 | the -386 didn't run on amd64?
| |
| 06:37 | <ogra> argh
| |
| 06:37 | * ogra did just noice that he edits in the wrong chroot since 30min | |
| 06:38 | <ogra> *sigh*
| |
| 06:38 | right, the -386 kernel is built with the most minimal instruction set -M486
| |
| 06:38 | and doesnt run on amd64 that way
| |
| 06:38 | <vagrantc> hrm.
| |
| 06:40 | that's probably the same on debian
| |
| 06:41 | <ogra> we used to have an -amd64 kernel ...
| |
| 06:41 | that was merged into -generic with the -686 one
| |
| 06:43 | <vagrantc> otavio: if you haven't already seen it: http://lintian.debian.org/reports/maintainer/pkg-ltsp-devel@lists.alioth.debian.org.html#ltsp
| |
| 06:44 | otavio: i can get the script-not-executable when i build it, but i can't get the invalid-po-file warnings
| |
| 06:47 | <ogra> gah
| |
| 06:47 | <wizzy__> The new ltsp client root is a combination of nbd/unionfs/squashfs. A squashfs is built, compressed, and mounted via nbd. Then there is supposedly a unionfs overlay (that I don't think works). How do I tell if unionfs is overlaying a file (besides looking at its content) and how do I debug this ?
| |
| 06:47 | <ogra> looks like all the calls to sed -i need to become sed -ie now
| |
| 06:47 | <vagrantc> ogra: -i -e
| |
| 06:47 | <ogra> yeah
| |
| 06:47 | still
| |
| 06:47 | thats silly
| |
| 06:47 | <vagrantc> ogra: -ie does something weird
| |
| 06:48 | * vagrantc likes -e anyways | |
| 06:48 | <ogra> well
| |
| 06:48 | it will berak tons of scripts
| |
| 06:48 | *break
| |
| 06:48 | wizzy__, SCREEN_02=shell in lts.conf and then see if anything is writable
| |
| 06:49 | wizzy__, what makes you think unionfs doesnt work
| |
| 06:49 | <vagrantc> wizzy__: what distro ?
| |
| 06:49 | <wizzy__> ogra: edubuntu gutsy - because the message at the top of lts.conf says I can put it elsewhere
| |
| 06:50 | I tried that, but it doesn't change from SCREEN_02=shell
| |
| 06:51 | <ogra> if you set SCREEN_02=shell it wont start anything else
| |
| 06:51 | <wizzy__> Do I need to remove it from the squashfs for it to appear ?
| |
| 06:51 | <ogra> you will have a shell on tty2
| |
| 06:51 | <wizzy__> yes, but I log in there, and look at the lts.conf, and it is the squashfs version, not the tftp/* version
| |
| 06:52 | <ogra> where exactly lies your tft version ?
| |
| 06:52 | *tftp
| |
| 06:52 | <wizzy__> It says put it at /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 06:52 | <ogra> and thats where you got it ?
| |
| 06:53 | <wizzy__> I put something there, but it does not overlay squashfs
| |
| 06:53 | Joe90 has quit IRC | |
| 06:53 | <ogra> and /var/lib/tftpboot/ltsp/i386/lts.conf exists ?
| |
| 06:54 | with that name ?
| |
| 06:54 | <wizzy__> ogra: yes, yes
| |
| 06:55 | and I rebooted
| |
| 06:55 | (the client)
| |
| 06:55 | <vagrantc> ogra: when i had nbdroot working on debian, the lts.conf from tftp never worked...
| |
| 06:55 | <ogra> right
| |
| 06:55 | i currently use it on a feshly built hardy
| |
| 06:55 | works perfectly here ... on my gutsy as well
| |
| 06:56 | <wizzy__> ogra: What can I do on the client to debug it ?
| |
| 06:56 | <ogra> note that it needs to be in ltsp/i386/ ....
| |
| 06:56 | <wizzy__> I have it at exactly the path above - I cut/paste
| |
| 06:57 | <ogra> well, you could try to get the file manually with a tftp client
| |
| 06:57 | to see the server side works as excpected first
| |
| 06:58 | <wizzy__> Does it /get/ it via tftp ? I thought it is unionfs magic
| |
| 06:58 | * vagrantc upgrades vagrantc's virtualbox debian ltsp install... | |
| 06:58 | <ogra> it gets it via tftp and then copies it over the one in the image
| |
| 06:59 | this all happens in initramfs
| |
| 06:59 | <wizzy__> Ok - I will give that a bash
| |
| 06:59 | <ogra> vagrantc, -e doesnt help :(
| |
| 07:00 | <vagrantc> ogra: you sure the file still contains a single tab ?
| |
| 07:00 | <ogra> i replace whatever is there with a tab
| |
| 07:00 | <vagrantc> ogra: might want to use something that catches any amount of whitespace
| |
| 07:00 | <ogra> i dont check if there is one already
| |
| 07:01 | its the writing, not the reading thats broken
| |
| 07:01 | <vagrantc> still works on debian sid ...
| |
| 07:02 | <ogra> hmm
| |
| 07:02 | there were no changes in ubuntus sed
| |
| 07:03 | and the above code makes 'Driver "cyrix"' to be 'Drivert"vesa"'
| |
| 07:03 | <vagrantc> bash/dash differences?
| |
| 07:04 | <wizzy__> "tftp 172.20.1.1 -c get ltsp/i386/lts.conf" works
| |
| 07:04 | <ogra> i couldnt imagine where that should have any effect on sed
| |
| 07:04 | <vagrantc> they tend to handle backslash characters differently ...
| |
| 07:04 | <ogra> i know
| |
| 07:04 | <vagrantc> well, if the shell is interpreting the tab somehow
| |
| 07:05 | <ogra> but does sed take that behavior from the shell ? couldnt imagine
| |
| 07:05 | <vagrantc> depends on how it's passed...
| |
| 07:06 | ogra: have you modified configure-x.sh ?
| |
| 07:06 | <ogra> no
| |
| 07:06 | its the identical one we use in gutsy
| |
| 07:06 | its the first time i try XSERVER=vesa in hardy though
| |
| 07:06 | so it might be there longer
| |
| 07:12 | chupa has quit IRC | |
| 07:12 | chupa has joined #ltsp | |
| 07:13 | <ogra> grr
| |
| 07:14 | * ogra wonders why it works fine with other variables but not XSERVER | |
| 07:14 | <ogra> X_MODE has no probs with tabs for example
| |
| 07:15 | <wizzy__> Jan 7 15:14:19 zululand in.tftpd[23920]: RRQ from 172.20.1.158 filename /lts.conf // sending NAK (1, File not found) to 172.20.1.158
| |
| 07:15 | <ogra> filename /lts.conf is surely wrong
| |
| 07:15 | <wizzy__> You say it is in the initramfs
| |
| 07:15 | <ogra> should be /ltsp/$arch/lts.conf
| |
| 07:16 | the path is assembled from $(basename filename)
| |
| 07:16 | where filename is the name of the kernel image
| |
| 07:16 | <wizzy__> Jan 7 15:13:52 zululand in.tftpd[23913]: RRQ from 172.20.1.158 filename /ltsp/i386/nbi.img
| |
| 07:18 | <ogra> ogra@ceron:~$ filename=/ltsp/i386/nbi.img
| |
| 07:18 | ogra@ceron:~$ tftpath=$(echo ${filename%/*}|tr -d '"')
| |
| 07:18 | <wizzy__> ltsp-server 5.0.39
| |
| 07:18 | <ogra> ogra@ceron:~$ echo $tftpath
| |
| 07:18 | /ltsp/i386
| |
| 07:19 | are you using etherboot ?
| |
| 07:19 | <wizzy__> Is that a greedy * in busybox or something ?
| |
| 07:20 | cliebow_ has joined #ltsp | |
| 07:20 | <ogra> or PXE ?
| |
| 07:20 | <wizzy__> It is RTL8139 with rom-o-matic from a long time ago
| |
| 07:20 | <ogra> hmm
| |
| 07:20 | that might be it
| |
| 07:20 | can you try a rom-o-matic image with PXE emulation ? (the recet ones all can do PXE)
| |
| 07:21 | seems the filename gets wiped in etherboot images or something like that
| |
| 07:21 | <wizzy__> ogra: I do not have all my rom burner stuff here ATM - stuck in the bush. No matter, I will move the file
| |
| 07:21 | <ogra> you could also just move lts.conf up two levels ;)
| |
| 07:21 | ariane has joined #ltsp | |
| 07:21 | <wizzy__> Ja, that is what I meant
| |
| 07:22 | <ogra> /opt/ltsp/i386/usr/share/initramfs-tools/scripts/ltsp_nbd
| |
| 07:22 | <wizzy__> Thanks - I didn't realise unionfs used tftp - now I can fix it.
| |
| 07:22 | <ogra> thats the responsible initramfs snippet btw
| |
| 07:23 | <wizzy__> I don't have the dev stuff here - that file doesn't exist. Should I update a wiki somewhere ?
| |
| 07:23 | <ogra> it mounts the image readonly via nbd, then mounts a tmpfs in the clients ram and then merges both in a unionfs ...
| |
| 07:23 | *then* it copies over lts.conf
| |
| 07:23 | <wizzy__> ok
| |
| 07:25 | <ogra> well, there is surely a bug,filing that one would help me to not forget about it :)
| |
| 07:25 | no need for wikipages atm
| |
| 07:25 | <wizzy__> where do I file ?
| |
| 07:25 | <ogra> launchpad.net
| |
| 07:25 | <wizzy__> k
| |
| 07:25 | <ogra> https://bugs.launchpad.net/ubuntu/+source/ltsp/+filebug
| |
| 07:26 | actually :)
| |
| 07:32 | <vagrantc> ogra: so, i'm guessing what you were saying earlier about ltspfs requiring hal recently hit debian sid ... no icons anymore
| |
| 07:32 | <ogra> no, currently we dont use hal at all
| |
| 07:32 | and gnomevfs works arund the icon stuff atm
| |
| 07:33 | but soon the access rights wil only be handled by polkit
| |
| 07:33 | currently the access rights for the session are already handled by consolekit ....
| |
| 07:34 | which means no administarative tasks at all anyore, everything that goes beyond /home is blocked by default
| |
| 07:34 | in the near future polkit and conkit will work hand in hand like an ACL mechanism
| |
| 07:34 | and dbus wont let anything through thats not autorized by them
| |
| 07:35 | since 80% of the gnome apps and good amount of KDE apps as well only communicate through dbus nowadays that makes the desktop barely usable
| |
| 07:35 | s/barely/hardly
| |
| 07:35 | <vagrantc> hm. well, at the moment, ltspfs don't create icons in nautilus from sid
| |
| 07:35 | <ogra> oh
| |
| 07:35 | it does in hardy
| |
| 07:36 | i tested that some mins ago
| |
| 07:36 | <vagrantc> yeah, guess i'll just switch :P
| |
| 07:36 | it was working a couple days ago in sid ... no idea what changed
| |
| 07:36 | <ogra> and it did in gutsy ...
| |
| 07:36 | gnomevfs likely
| |
| 07:36 | the mounts happen i bet
| |
| 07:37 | there is also a gconf key in nautilus that rules if icons are shown at all
| |
| 07:38 | you might want to check that with gconf-editor
| |
| 07:40 | <vagrantc> no new libgnomevfs* uploads since november
| |
| 07:40 | <ogra> nautilus ?
| |
| 07:41 | <vagrantc> ditto
| |
| 07:41 | yeah, the mounts happen...
| |
| 07:41 | user can read them and stuff
| |
| 07:42 | and this is without all my crazy patches
| |
| 07:42 | <ogra> are you sure its not your playing ?
| |
| 07:42 | hmm
| |
| 07:42 | <vagrantc> straight from debian sid
| |
| 07:42 | <ogra> did debian enable consolekit already ?
| |
| 07:42 | <vagrantc> how would i check?
| |
| 07:42 | <ogra> (even though it shouldnt have any effect yet on ltspfs)
| |
| 07:43 | well, is console-kit-daemon running
| |
| 07:43 | subir has quit IRC | |
| 07:43 | <vagrantc> no
| |
| 07:44 | <ogra> dpkg -l consolekit
| |
| 07:44 | <vagrantc> although, this isn't the exact same setup ... this is an upgrade from etch
| |
| 07:44 | <ogra> we have 0.2.3-3ubuntu1
| |
| 07:45 | <vagrantc> it's not installed ...
| |
| 07:45 | <ogra> 2.22 will require it
| |
| 07:45 | (gnome 2.22
| |
| 07:45 | )
| |
| 07:45 | <vagrantc> 0.2.3-3 available
| |
| 07:46 | <ogra> what do you have in sid atm ?
| |
| 07:46 | (gnome)
| |
| 07:46 | <vagrantc> on 2.20 for most gnome related stuff
| |
| 07:46 | <ogra> thats what we have in gutsy
| |
| 07:46 | <vagrantc> this is perplexing
| |
| 07:46 | <ogra> yeah
| |
| 07:46 | i dont see a reason why it shuldnt work
| |
| 07:47 | <vagrantc> i should head down to freegeek, test it on the setup that was working a couple days ago, upgrade, and see if it's still working
| |
| 07:47 | <ogra> yeah
| |
| 07:47 | or try a fresh virtbox setup
| |
| 07:47 | <vagrantc> i need to scrounge more drive space for that :)
| |
| 07:48 | * ogra built a raid0 machine with 4G and 300M/s disk tranfser rates over christmas .... | |
| 07:48 | <vagrantc> big difference is one is doing full-blown (or mostly full) gnome, while this is icewm + nautilus
| |
| 07:48 | <ogra> ltsp-build-client (with an apt-proxy in the lan) takes less than 5 min :)
| |
| 07:48 | <vagrantc> which was working with etch as the server and a sid ltsp
| |
| 07:51 | * ogra goes for a coffeebreak | |

| |
| 08:26 | <vagrantc> PerfDave: the answer is no
| |
| 08:28 | well, maybe progress has been made in the last few years, but i've been disappointed by all of the dynamic proxying alternatives ...

| 08:29 | <otavio> hi

| 08:29 | <vagrantc> best luck i've had is using squid, and then parsing the logs to determine which packages to mirror

| |
| 10:24 | * ogra agrees | |
| 10:25 | <vagrantc> so there appears to be something going on running gnome that doesn't happen when running nautilus
| |
| 10:25 | ltspfs is working fine with gnome, just not with icewm + nautilus
| |
| 10:25 | <ogra> so there are services missin i guess
| |
| 10:26 | did you try to start gnome-settings-daemon with nautilus ?
| |
| 10:26 | or at least gconfd
| |
| 10:27 | * ogra pokes around in consolekit ... | |
| 10:27 | <ogra> there seems to be a pam module, i wonder if we could just use that
| |
| 10:30 | <vagrantc> ogra: i didn't try starting gnome-settings-daemon ... pretty sure gconfd was running
| |
| 10:32 | <ogra> ogra@ceron:~/devel/packages/consolekit-0.2.3$ ps ax|grep vfs
| |
| 10:32 | 28635 ? S 0:00 /usr/lib/gnome-vfs-2.0/gnome-vfs-daemon
| |
| 10:32 | 30105 ? S 0:00 /usr/lib/gnome-vfs-2.0/gnome-vfs-daemon
| |
| 10:32 | seems thats started as well for me here
| |
| 10:32 | no idea by what but it probably helps to have it running
| |
| 10:33 | <vagrantc> ok
| |
| 10:38 | hmm... doesn't seem to run manually
| |
| 10:38 | staffencasa has joined #ltsp | |
| 10:39 | <vagrantc> fails to connect to dbus ... dbus is running
| |
| 10:39 | <ogra> likely somehow started by gnome-session
| |
| 10:39 | i guess you dont have the right dbus privs if you start it from a terminal
| |
| 10:39 | <vagrantc> yeah...
| |
| 10:40 | now i've got a sid virtualbox ltsp server and a virtualbox sid ltsp client that has gnome-desktop
| |
| 10:40 | i'm pretty happy with that :)
| |
| 10:40 | <ogra> on your laptop ?
| |
| 10:40 | <vagrantc> yeah
| |
| 10:41 | <ogra> and thats usable
| |
| 10:41 | i mean ...
| |
| 10:41 | does the mouse move more than every 20min ?
| |
| 10:41 | <vagrantc> upgraded to a 866MHz with 512MB of ram
| |

| |
| 10:41 | <ogra> oh
| |
| 10:41 | congrats :)
| |
| 10:41 | <vagrantc> heh
| |
| 10:41 | 6-8 hours of battery life :)
| |
| 10:42 | <ogra> wow, more than i get out of the classmate
| |
| 10:42 | <vagrantc> virtualbox works great on this

| 10:45 | <aboo0ood> hi everybody, i have a question about LTSP-loadbalancer .. is there anything about balancing per application ?
| |
| 10:46 | <ogra> aboo0ood, you will have to wait for francis (fgiraldeau), the loadbalancer stuff isnt part of the default ltsp
| |
| 10:46 | <vagrantc> aboo0ood: not yet, really.
| |
| 10:47 | tux_440volt has joined #ltsp | |
| 10:47 | <aboo0ood> ogra, vagrantc : What kind of balancing does LTSP-5 offer ?
| |
| 10:48 | <ogra> per session ... you can provide a list of different servers the user can select from
| |
| 10:48 | <tux_440volt> hi ! while trying to boot my clients i get /etc/rc.early_sysinit not found
| |
| 10:48 | DawnLight has joined #ltsp | |
| 10:49 | <aboo0ood> ogra, vagrantc : Is Francis working on a per application solution ? I read about LTSP-loadbalancer and if i didn't miss anything i didn't see anything about balancing per application
| |
| 10:49 | <vagrantc> you can also control which server gets logged in by default with a script...
| |
| 10:49 | aboo0ood: that's an order of magnitude more complicated
| |
| 10:50 | <DawnLight> what can i use for network sound in the debian etch packages?
| |
| 10:50 | <vagrantc> if you really want to reduce the load on the server, use diskless workstations
| |
| 10:50 | DawnLight: i *think* esound should work, but it's been so long since i've tried.
| |
| 10:51 | DawnLight: the etch ltsp backports should work with pulseaudio+alsa
| |
| 10:51 | <aboo0ood> vagrantc, ogra : i am thinking about developing such a solution and trying to figure out the possibilities
| |
| 10:51 | <DawnLight> backports? hmm...
| |
| 10:52 | <aboo0ood> vagrantc, ogra : why did u say it's orders of magnitude more complicated ?
| |
| 10:52 | <ogra> aboo0ood, the prob is that you need a network auth mechanism in place (ldap, nis etc) which is simply beyond ltsp
| |
| 10:52 | <aboo0ood> an order *
| |
| 10:53 | <ogra> its rather a "network design and setup" than an application :)
| |
| 10:53 | <aboo0ood> ogra, can't this be done over ssh ?
| |
| 10:53 | prpplague has joined #ltsp | |
| 10:53 | <aboo0ood> the idea of "ssh -X" .. can't this be used ?
| |
| 10:53 | prpplague has left #ltsp | |
| 10:53 | <ogra> sure, but you still need to make sure that auth is provided and in sync on all servers ... DISPLAY variables are set etc
| |
| 10:54 | its trivial to set that up on a single network as a specific solution in a company or so ...
| |
| 10:55 | but its very hard to build something like that in a manner to have it set up everything automatically for you
| |
| 10:55 | in a functional basic state at least and integrated with different desktop environments etc
| |
| 10:56 | <vagrantc> whereas, it's fairly simple to allow multiple login servers
| |
| 10:56 | aboo0ood: why do you need per-application load balancing?
| |
| 10:57 | <aboo0ood> vagrantc, i thought it would be more beneficial in massive LTSP solutions
| |
| 10:57 | <vagrantc> but no specific implementation?
| |
| 10:57 | <aboo0ood> vagrantc, not yet
| |
| 10:58 | vagrantc, don't u think it would be better than per session balancing ?
| |
| 10:59 | vagrantc, more dynamic ..
| |
| 10:59 | <vagrantc> more headache
| |
| 10:59 | <aboo0ood> lol
| |
| 11:00 | yes, but for the developer maybe, not for the user
| |
| 11:00 | <vagrantc> per session is simple to understand and troubleshoot
| |
| 11:00 | yes, as long as everything works perfectly
| |
| 11:00 | but when things break, it will break much more badly
| |
| 11:01 | i think the simplest form of load balancing would be to get local applications working
| |
| 11:02 | <ogra> that still needs a new sshfs
| |
| 11:02 | <vagrantc> that seems more feasible to me
| |
| 11:02 | <ogra> which scottie hasnt done yet
| |
| 11:02 | <vagrantc> indeed
| |
| 11:02 | <ogra> and session side integration
| |
| 11:02 | <vagrantc> details...
| |
| 11:02 | <ogra> (menu integration etc)
| |
| 11:02 | indeed
| |
| 11:02 | * ogra doesnt count on localapps for hardy | |
| 11:03 | <vagrantc> i'm hoping to finally fix the double-mount issue for ltspfs... and finally have a working setup where i can test it
| |
| 11:03 | <ogra> feature freeze is in five weeks ...
| |
| 11:03 | right i'm concentrating on bugs as well
| |
| 11:04 | and most of my time is eaten by classmate anyway
| |
| 11:04 | <vagrantc> i actually have a working fix i like ...but it still causes an extra mount to show up... which is better than 2 mounts for each device... but still
| |
| 11:04 | DawnLight has left #ltsp | |
| 11:04 | <ogra> hmm
| |
| 11:04 | i think we have a fix in the ubuntu gnomevfs pacage
| |
| 11:04 | <vagrantc> that's a workaround, not a fix :P
| |
| 11:05 | i've been thinking about this so much i feel near to fixing it
| |
| 11:06 | <ogra> did you have a look at ignore_ltspfs_volumes.patch in the ubuntu gnomevfs package ?
| |
| 11:06 | <aboo0ood> what is required to configure the network for ssh tunneling ? and what's hard about it ?
| |
| 11:07 | <ogra> vagrantc, that patch is in ubuntu since edgy at least with this reason you could probably push it through in debian :)
| |
| 11:14 | <vagrantc> ogra: i'd still prefer to fix it outside of gnome-vfs
| |
| 11:15 | primeministerp has quit IRC | |
| 11:21 | <vagrantc> ogra: well, i came up with a one-line patch to fix the double-mount issue :)
| |
| 11:21 | change --bind to --move
| |
| 11:23 | well... maybe a little more patching ... but it's basically working
| |
| 11:25 | i seem to recall etch still behaving a little oddly...
| |
| 11:25 | with --move
| |
| 11:26 | tux_440volt has quit IRC | |
| 11:36 | <vagrantc> ok, so 2 lines of patches has got it doing a single mount and unmounting the ltspfs fuse mount ... it leaves the directories behind, though...

| 12:43 | <sutula> vagrantc: IIRC, there's been a couple of bugs that people are working around, at least in the etch backports version: a) In /opt/ltsp/i386/usr/share/ldm/rc.d/S10-delayed-mounter, change "ssh -S" to "ssh -X -S", b) delete env['DISPLAY'] = 'localhost:10.0' from /usr/sbin/ltspfsmounter, line 21
| |
| 12:44 | vagrantc: Just wondering if a fix is imminent or should this be added to http://wiki.debian.org/LTSP/Howto
| |
| 12:46 | <vagrantc> sutula: yeah
| |
| 12:46 | sutula: a fix is in progress, but add it to the wiki anyways
| |
| 12:46 | * sutula does that to his kids too, when they ask an "or" question :) | |
| 12:46 | <vagrantc> sutula: we can always remove it when it's no longer relevent
| |
| 12:47 | <sutula> vagrantc: K, I'll add it
| |
| 12:47 | <vagrantc> ldm in sid already has the fix
| |
| 12:47 | although i may muck things up a bit more
| |
| 12:48 | sutula: how's your C code?
| |
| 12:49 | think i'm on the verge of fixing http://bugs.debian.org/443200
| |
| 12:49 | otavio: i need some help with C code in ltspfs... lbmount.c, specifically
| |
| 12:49 | <sutula> vagrantc: It's good...what do you need?
| |
| 12:49 | <vagrantc> sutula: oh, excellent ...
| |
| 12:50 | sutula: well, i'm trying to fix lbmount.c to only do a single mount ... i've almost got it, just can't figure out how the is_mounted function is working...
| |
| 12:51 | sutula: i'll paste what i have to pastebot
| |
| 12:51 | <sutula> vagrantc: K
| |
| 12:53 | <ltsppbot> "vagrantc" pasted "lbmount.c patched to use mount --move instead of mount --bind" (302 lines) at http://pastebot.ltsp.org/408
| |
| 12:55 | <vagrantc> sutula: i think there's something in is_mounted function ... probably in the while loop ... which is looking at the wrong directory ...
| |
| 12:55 | <sutula> vagrantc: Looking

| |
| 12:57 | * vagrantc wonders what "realpath" does | |
| 12:57 | <vagrantc> a path sanitizer?
| |
| 12:57 | ah, it actually has a man page
| |
| 12:59 | * vagrantc wonders what strcmp is doing ... | |
| 12:59 | * vagrantc wonders a lot | |
| 13:00 | Egyptian[Home1 has quit IRC | |
| 13:00 | <sutula> vagrantc: strcmp is comparing strings, returns 0 if they compare exactly
| |
| 13:00 | <vagrantc> sutula: right ... but the code is ... if (!strcmp(targetpath1, targetpath2)) {
| |
| 13:01 | ah!
| |
| 13:02 | it's making sure you're not checking the same directory that it's bind-mounted to ...
| |
| 13:02 | but in this case, that's the only one we want to check
| |
| 13:03 | * sutula doesn't seem to have enough of vagrantc's context, so continues to just answer vagrantc's questions | |
| 13:03 | <vagrantc> :)
| |
| 13:03 | <otavio> vagrantc: say
| |
| 13:03 | <vagrantc> patching all this C is really stretching my limits
| |
| 13:04 | i'm amazed i've gotten this far
| |
| 13:04 | * Gadi hugs perlcc :) | |
| 13:05 | <otavio> vagrantc: this if runs only if both variable are _different_
| |
| 13:05 | vagrantc: strcmp returns 0 if they're iqual
| |
| 13:05 | _e_qual
| |
| 13:06 | <vagrantc> sutula: ok... context ... currently lbmount does a few things... it makes /media/USERNAME/DEVICE ... it checks if /tmp/.USERNAME-ltspfs/DEVICE is fuse-mounted and owned by USERNAME, and then bind-mounts /tmp/.USERNAME-ltspfs/DEVICE to /media/USERNAME/DEVICE
| |
| 13:06 | sutula: that's the mount mode ...
| |
| 13:07 | sutula: then it basically does the opposite .... umounts /media/USERNAME/DEVICE, checks if /tmp/.UERNAME-ltspfs/DEVICE is owned by USERNAME and umounts it, and then removes /media/USERNAME/DEVICE and /media/USERNAME (if empty)
| |
| 13:09 | my patch is different in that instead of --bind mounting /tmp/.USERNAME-ltspfs/DEVICE it bind --move's it ... so at umount time, /tmp/.USERNAME-ltspfs/DEVICE doesn't exist anymore

| 13:10 | <vagrantc> otavio: yeah, i figured that out from the man page, i just couldn't figure out how it was used in the code at first
| |
| 13:10 | otavio: i.e. why it was used
| |
| 13:10 | but now i get it
| |
| 13:11 | and realpath sets a variable based on an argument, more or less... ?
| |
| 13:12 | <sutula> vagrantc: Yes...get's rid of symbolic links, extra "./", etc, in the pathname
| |
| 13:13 | vagrantc: Think of it as sanitizing the path, but should not affect the logic
| |
| 13:14 | <vagrantc> i just was having a hard time figuring out where the targetpath* variables were coming from

| |
| 13:19 | SIZE=64
| |

| |
| 13:19 | <vagrantc> create it
| |

| |
| 13:19 | <ltsp> ok ! i try it thank you vagrantc
| |
| 13:22 | vagrant i having issues wich users pendrivers, the option in nautilus for safe remove dont umount it
| |
| 13:22 | <vagrantc> you can just unplug them after 2 seconds of inactivity
| |
| 13:24 | <ltsp> this "bug" its normal on ltsp terminals ?
| |
| 13:26 | <vagrantc> ltsp: i've heard others report it
| |
| 13:27 | ltsp: the way ltspfs works is that after 2 seconds of inactivity on the client, in un-mounts the filesystem ... the server still sees the ltspfs mount, but the media is not actually mounted ...
| |
| 13:27 | so unless you write to it and immediately yank it out, your media should be fine.
| |
| 13:28 | <ltsp> great !
| |
| 13:28 | sorry but my english its sooo poor
| |
| 13:28 | :(
| |
| 13:28 | <vagrantc> what nautilus does or doesn't do... i've used very little nautilus
| |
| 13:28 | not a problem
| |
| 13:28 | <ltsp> i need other question for you
| |
| 13:29 | in my laboratory , the users contantly remove/delete my desktop icons on terminals
| |
| 13:29 | exist one way for i'm lock the desktop icons ?
| |
| 13:33 | <vagrantc> no idea
| |
| 13:33 | i don't really use desktops much
| |
| 13:34 | maybe someone else
| |
| 13:34 | <sep> ltsp, make the files owned by root ? :)
| |
| 13:34 | <vagrantc> that would probably work
| |
| 13:35 | <ltsp> chown root.root /home/$USER/Desktop/* ?
| |
| 13:35 | <vagrantc> they'd probably still have permission to remove them
| |
| 13:35 | ltsp: try it out...
| |
| 13:36 | ltsp: well, try with one user first
| |
| 13:36 | <ltsp> i try it thats works but the icons have no pictures
| |
| 13:36 | only X rede on icons
| |
| 13:36 | <sutula> ltsp: Make a copy of what you want on each desktop in a separate directory, and have a login script to copy it to the desktop on login?
| |
| 13:37 | <vagrantc> ltsp: you may need to give them read permission...
| |
| 13:37 | <ltsp> exempla = openoffice icons ---> X (red)
| |
| 13:37 | its the good idea sutula
| |
| 13:37 | * sutula doesn't know enough gnome to do that, but suspects that there's an IRC channel somewhere (else) where people would know | |
| 13:40 | <ltsp> for example i know lock the bckground proprierty , the command is:
| |
| 13:40 | sudo chmod 700 /usr/bin/gnome-background-properties
| |
| 13:40 | this command lock the background options
| |
| 13:42 | <johnny> i always use sabayon for this..
| |
| 13:42 | isn't there a way to use gconf to mark a property as mandatory?
| |
| 13:42 | <ltsp> sabayon dont work for me :(
| |
| 13:43 | <vagrantc> sutula: ok ... i'm going crazy... i'm getting an error message ... it's printing using fprintf ... i'm adding a line immediately before it with the exact same syntax, yet i never see the output
| |
| 13:43 | <johnny> it will be soon :)
| |
| 13:43 | i've been submitting some patches for it
| |
| 13:43 | or rather.. committing some patches
| |
| 13:43 | first some simple ones.. and then i'll be working on the heavier issues
| |
| 13:44 | <sutula> vagrantc: Can you pastebot it again?

| |
| 13:47 | <ltsp> guys i can use LDM2 (gutsy) on feisty (ldm python) ?
| |
| 13:47 | <sutula> vagrantc: That almost sounds like you missed compiling it or are executing the old version. Is that possible?
| |
| 13:48 | <vagrantc> sutula: m5sums match with the freshly compiled version
| |
| 13:48 | no warnings or errors at compile time
| |
| 13:49 | <sutula> vagrantc: There's nothing wrong with the "C" syntax in that area
| |
| 13:50 | <johnny> ltsp, i wouldn't try
| |
| 13:51 | * vagrantc was putting the file in the wrong directory | |
| 13:51 | <sutula> vagrantc: That sounds more like it
| |
| 13:51 | <ltsp> humm LDM2 is more faster than LDM
| |
| 13:51 | <johnny> then use gutsy
| |
| 13:51 | * vagrantc wonders how many times | |
| 13:52 | <ltsp> gutsy ltsp version dont boot wich nbi mages on my terminals
| |
| 13:52 | only pxelinux.0
| |
| 13:52 | <vagrantc> ltsp: what version of etherboot are you using?
| |
| 13:53 | <ltsp> 5.4.3
| |
| 13:53 | <johnny> mine boots fine with nbi
| |
| 13:53 | <ltsp> on feisty nbi image works , but in gutsy dont work
| |
| 13:54 | <johnny> you should generate a new chroot

| 13:55 | but dont work wich nbi images
| |
| 13:56 | <johnny> must be some small issue for that
| |
| 13:56 | <ltsp> and i listen in ltsp br discuss list ( i'm from brazil) ltsp gutsys version is soo unstable
| |
| 13:57 | <johnny> hmm.. my ltsp is stable.. i just had a problem with autologn
| |
| 13:57 | and firefox
| |
| 13:57 | but that isn't really related to ltsp tho
| |
| 13:59 | <ltsp> humm i try again use ltsp wich ubuntu 7.10
| |
| 14:02 | ltsp in gutsy is more faster than feisty version ?
| |
| 14:02 | i have 20 terminals celeron 333+64/128MB, ltsp 5 boot is slow :(
| |
| 14:03 | <johnny> 333+64 ?
| |
| 14:03 | bobby_C has joined #ltsp | |
| 14:03 | <ltsp> celeron 333 Mhz wich 64 MB SDR
| |
| 14:03 | or 128 MB SDR
| |
| 14:03 | <johnny> 64mb ram is always going to be a bit slow
| |
| 14:03 | if you run gnoe
| |
| 14:03 | gnome*
| |
| 14:03 | or firefox/openoffice
| |
| 14:03 | sep has quit IRC | |
| 14:04 | <ltsp> yes ! and firefox and openoffice
| |
| 14:04 | the terminals freezes any times on powerpoint apresentations
| |
| 14:04 | <johnny> they aren't powerful enough..
| |
| 14:04 | <ltsp> :(
| |
| 14:04 | 64 mb is no enough ?
| |
| 14:04 | <johnny> nope
| |
| 14:05 | <ltsp> "thinclients" :(
| |
| 14:05 | <johnny> not for openoffice at all
| |
| 14:05 | hmm.. what did the docs say..
| |
| 14:05 | * johnny looks | |
| 14:05 | <ltsp> i not understand sorry
| |
| 14:06 | my english is so terribly
| |
| 14:06 | ¬¬
| |
| 14:06 | <johnny> how powerful is the server?
| |
| 14:06 | what are the specs?
| |
| 14:06 | maybe you want to use xfce on the clients, and then upgrade the server
| |
| 14:06 | <ltsp> my server is the Atlhon 64 3700+ wich 2 GB DDR + 80 GB HDD SATA II
| |
| 14:06 | <johnny> ldm in gutsy will make it boot faster, but that's all that will change
| |
| 14:06 | <ltsp> :(
| |
| 14:07 | <johnny> it won't make much else go any faster
| |
| 14:07 | hmm how many clients/
| |
| 14:07 | <ltsp> 20
| |
| 14:07 | 2 GB is enough ?

| 14:09 | <ltsp> 256 + (60 * 20) = 256 + 1200 = 1456 MB
| |
| 14:09 | is enough :D
| |
| 14:09 | <johnny> do you use the server as a desktop?
| |
| 14:10 | <ltsp> yes :(
| |
| 14:10 | for professor
| |
| 14:10 | professor pc
| |
| 14:10 | <johnny> add that in too
| |
| 14:11 | and those numbers don't take firefox or openoffice into account
| |
| 14:11 | that's for basic functionality
| |
| 14:11 | those two apps are notoriously memory hungry
| |
| 14:11 | :)
| |
| 14:11 | try with firefox beta 2
| |
| 14:11 | firefox3 beta2
| |
| 14:11 | you might do a bit better with that
| |
| 14:11 | i guess you'll be fine with 128mb on the client
| |
| 14:11 | but 64 is kinda tight with gnome
| |
| 14:12 | even for what happens to run locally on the server
| |
| 14:12 | <otavio> vagrantc: sorry, was on phone
| |
| 14:12 | <johnny> whihc isn't much.. but enough :)
| |
| 14:12 | <ltsp> firefox3 beta is hungry less memory ?
| |
| 14:12 | <otavio> vagrantc: wants me to take a look on it, now?
| |
| 14:12 | <johnny> yes
| |
| 14:12 | firefox2 is horrendous to run
| |
| 14:12 | <ltsp> go go apt-get install !
| |
| 14:12 | <johnny> on thin clients :)
| |
| 14:12 | or anything reallly :)
| |
| 14:13 | many people were saying they were being treated as second classs citizens to windows
| |
| 14:13 | in relation to firefox
| |
| 14:13 | but firefox3 is much better so far
| |
| 14:13 | <ltsp> humm i try install firefox3 beta
| |
| 14:13 | <johnny> i've been running it on my box for a few weeks now
| |
| 14:13 | it's not in apt-get yet
| |
| 14:14 | only alpha8
| |
| 14:14 | <ltsp> wich xfce
| |
| 14:14 | dou know where im find feisty deb package ?
| |
| 14:14 | <johnny> if you are ever interested in getting sabayon working tho, talk to me, as i am now committing various patches
| |
| 14:14 | no
| |
| 14:14 | Blinny has joined #ltsp | |
| 14:14 | <johnny> you're going to have to wait on that i think, unless it's already in hardy-backports..
| |
| 14:15 | err feisty-backports
| |
| 14:15 | <vagrantc> otavio: well, i've made good progress ...
| |
| 14:15 | <ltsp> hauuha
| |
| 14:15 | "hardy-backports"
| |
| 14:15 | <vagrantc> otavio: now i'm just perplexed why it works for floppy, but doesn't quite work for cdrom
| |
| 14:17 | <ltsp> its normal saves on floppy have a small delay ? 10 20 seconds to save
| |
| 14:17 | <johnny> yes
| |
| 14:17 | seems to be
| |
| 14:17 | seen that in feisty and gutsy
| |
| 14:17 | <vagrantc> otavio: maybe i spoke too soon.
| |
| 14:17 | <otavio> ?
| |
| 14:18 | vagrantc: it works?
| |
| 14:18 | <ltsp> feisty
| |
| 14:18 | <vagrantc> otavio: mostly
| |
| 14:18 | <Blinny> ...mostly...
| |
| 14:19 | <vagrantc> otavio: i'm totally confused why it doesn't work for cd but works for floppy
| |
| 14:19 | otavio: and it doesn't remove /media/USERNAME/DEVICE when it's done ...
| |
| 14:19 | <otavio> where I can grab this code?
| |
| 14:19 | <ltsp> johnny for better performace i need increase my terminals memorys ?
| |
| 14:19 | <vagrantc> otavio: i'll push a branch
| |
| 14:20 | <otavio> vagrantc: and how I can test it?
| |
| 14:20 | <ltsp> i'm downloading firefox beta2
| |
| 14:20 | <vagrantc> otavio: you'd need a sid LTSP server and a thin client ...
| |
| 14:20 | otavio: i've been using virtualbox quite happily
| |
| 14:20 | <otavio> vagrantc: oh! it'll take a long time to setup it
| |
| 14:20 | <johnny> firefox3 will prolly help
| |
| 14:20 | <vagrantc> otavio: yes...
| |
| 14:20 | <johnny> abiword would be better for you than openoffice for documents
| |
| 14:21 | and gnumeric better for spreadsheets
| |
| 14:21 | <ltsp> jonny i have other issues wich pendrive users
| |
| 14:21 | <otavio> vagrantc: I'll have dinner and will be back later. (~20min)
| |
| 14:21 | <johnny> but there is no replacement for presentations yet
| |
| 14:21 | afaik
| |
| 14:21 | <otavio> vagrantc: then I'll get your branch and we look at it together. ok?
| |
| 14:21 | <ltsp> abiword is soo poor :(
| |
| 14:21 | <johnny> by better. i mean lower memory usage and faster
| |
| 14:21 | <vagrantc> otavio: ok
| |
| 14:22 | <ltsp> johnny any pendrivers like a mp3players the ltsp can't mount them
| |
| 14:23 | <johnny> in feisty?
| |
| 14:23 | <ltsp> yes
| |
| 14:24 | <johnny> never had that problem
| |
| 14:24 | <ltsp> i dont test in gutsy yet
| |
| 14:24 | <johnny> gutsy there is a known problem, and some fixes
| |
| 14:24 | i just lack the unmount option
| |
| 14:24 | as mentioned earlier
| |
| 14:24 | <ltsp> umount option dont work in nautilus but vagrant says that is normal
| |
| 14:25 | <johnny> yeah i saw that
| |
| 14:25 | but they did mount for me in feisty
| |
| 14:25 | i don't know what else to say about that as i don't have any feisty installs around anymore
| |
| 14:25 | <ltsp> hum
| |
| 14:26 | johnny how 'im install the firefox3 beta 2 ?
| |
| 14:26 | <johnny> unpack it somewhere
| |
| 14:26 | in /usr/local
| |
| 14:26 | /usr/local/apps/ maybe
| |
| 14:26 | i don't know what is preferred
| |
| 14:26 | <ltsp> hum ok
| |
| 14:27 | and creat a sym link to executable
| |
| 14:27 | <johnny> yes
| |
| 14:29 | <ltsp> ltsp@ltsp:~$ /home/ltsp/Desktop/firefox/firefox-bin /home/ltsp/Desktop/firefox/firefox-bin: error while loading shared libraries: libxul.so: cannot open shared object file: No such file or directory
| |
| 14:29 | :(
| |
| 14:30 | <johnny> not over the firefox2 tho
| |
| 14:30 | make a firefox3
| |
| 14:30 | and not directly to the bin
| |
| 14:30 | npman has joined #ltsp | |
| 14:31 | <ltsp> ltsp@ltsp:~$ /home/ltsp/Desktop/firefox/firefox and open my firefox 2.0.11 O_o
| |
| 14:31 | i need remove the ff 2.0.11 ?
| |
| 14:31 | <johnny> no
| |
| 14:31 | do you have firefox2 open tho?
| |
| 14:31 | <ltsp> yes
| |
| 14:31 | <johnny> if you have firefox2 open, it will open firefox2
| |
| 14:32 | and not firefox3
| |
| 14:32 | <ltsp> works now !
| |
| 14:32 | i close firefox 2 :P
| |
| 14:33 | <johnny> i'm going to be upgrading my clients to firefox3 later on tonight
| |
| 14:33 | keeping the old one tho
| |
| 14:34 | gotta shower..bbiab
| |
| 14:36 | <ltsp> firefox 3 beta 2 is soo cute haahhaa

| |
| 14:54 | too busy
| |
| 14:54 | ok ...
| |
| 14:54 | otavio: do you just want to look at the code, or are you preparing an LTSP environment?
| |
| 14:55 | <otavio> vagrantc: want to take a look so I could try to help you to hunt it

| |
| 15:01 | so, what i don't understand is why when cdpinger is called ... it doesn't seem to do the "mount --move" part ...
| |
| 15:05 | <otavio> vagrantc: what file I should take a look?
| |
| 15:07 | jammcq has joined #ltsp | |
| 15:07 | <vagrantc> otavio: main things to look at are src/lbmount.c
| |
| 15:08 | otavio: scripts/ltspfsmounter
| |
| 15:08 | otavio: src/cdpinger.c
| |
| 15:08 | otavio: i think i've got ltspfsmounter working pretty good
| |
| 15:13 | zodman has quit IRC | |
| 15:13 | cliebow_ has quit IRC | |
| 15:14 | <vagrantc> otavio: on the server-side, you initiate an ltspfs mount by calling... ltspfsmounter ... so the udev rules and ldm login scripts call that
| |
| 15:15 | otavio: ltspfsmounter creates a dir in /tmp, fuse mounts ltspfs, and calls lbmount to mkdir /media/USERNAME/DEVICE, and then bind-mounts (or moves) to /media/USERNAME/DEVICE
| |

| 15:25 | <vagrantc> DGHTSP
| |
| 15:25 | <otavio> vagrantc: humm
| |
| 15:26 | <vagrantc> otavio: any ideas ... ?
| |
| 15:26 | <otavio> vagrantc: ltspmounter is called by udeb with add, right?
| |
| 15:26 | <vagrantc> otavio: no
| |
| 15:26 | <otavio> ?
| |
| 15:26 | <vagrantc> otavio: udev, you mean?
| |
| 15:26 | <otavio> yes yes
| |
| 15:26 | udev
| |
| 15:26 | sorry
| |
| 15:26 | <vagrantc> ah, yes...
| |
| 15:27 | <otavio> too used to write udeb ;-)
| |
| 15:27 | <vagrantc> scripts/*_fstab_entry is what calls ltspfsmounter
| |
| 15:27 | <otavio> right
| |
| 15:27 | <vagrantc> as well as ldm's /usr/share/ldm/rc.d/*
| |
| 15:27 | <otavio> good
| |
| 15:27 | so it then calls it for the CDROM ... right?
| |
| 15:27 | <vagrantc> well, cdpinger calls *_fstab_entry
| |
| 15:28 | <otavio> cdpinger?
| |
| 15:28 | <vagrantc> since there's no udev events for cd insertion or removal
| |
| 15:28 | <otavio> openin git
| |
| 15:28 | <vagrantc> otavio: src/cdpinger
| |
| 15:28 | <otavio> ahh ok
| |
| 15:28 | <vagrantc> otavio: src/cdpinger.c
| |
| 15:28 | <otavio> well .. there's hall for it
| |
| 15:28 | hal does have cd pinger like
| |
| 15:29 | vagrantc: good. It basically pings CD every 3 seconds and check its status
| |
| 15:29 | <vagrantc> everything works with cdpinger, except it doesn't mount to /media/USERNAME
| |
| 15:30 | i.e. the /tmp/.USERNAME-ltspfs/cdrom mount kicks in
| |
| 15:30 | <otavio> vagrantc: so it _does_ calls add_fstab_...?
| |
| 15:30 | <vagrantc> otavio: yes, cdpinger calls add_fstab_entry and remove_fstab_entry ...
| |
| 15:30 | you know what ...
| |
| 15:30 | the floppy never gets called through add_fstab_entry or remove_fstab_entry
| |
| 15:30 | it's always done through the LDM scripts
| |
| 15:30 | <otavio> humm
| |
| 15:31 | <vagrantc> that's the difference ... though both do call ltspfsmounter
| |
| 15:31 | <otavio> if _you_ call add_fstab byhand for the CD, does it work too?
| |
| 15:32 | <vagrantc> ah, good thinking
| |
| 15:33 | ldm calls .... ssh -X -S ${LDM_SOCKET} ${LDM_SERVER} "/usr/sbin/ltspfsmounter ${DIR} add"
| |
| 15:33 | and add_fstab_entry: /usr/bin/ssh -X -S ${LDM_SOCKET} ${SERVER} \ "/usr/sbin/ltspfsmounter ${MOUNTPOINT} add"
| |
| 15:35 | <otavio> humm
| |
| 15:35 | and are their equivalent?
| |
| 15:35 | SERVER == LDM_SERVER?
| |
| 15:35 | DIR == MOUNTPOINT?
| |
| 15:36 | SERVER looks to be
| |
| 15:36 | but not sure since I cannot try it here
| |
| 15:38 | Guaraldo has left #ltsp | |
| 15:39 | <otavio> vagrantc: checked the values?
| |
| 15:40 | vagrantc: try to call ssh by hand and see if it works or not
| |
| 15:40 | <vagrantc> add_fstab_entry gets an appropriate value for $SERVER
| |
| 15:40 | it's a little tricky to check each thing
| |
| 15:40 | and i got to eat some food :)
| |
| 15:40 | <otavio> ahh ok
| |
| 15:40 | np, ping me when back
| |
| 15:41 | vagrantc: ah, my mom sent you a "hello"
| |
| 15:41 | <vagrantc> otavio: hola a tu madre
| |
| 15:41 | <otavio> vagrantc: :-) We're looking forward to meet you again on Argentina, later this year! .-)
| |
| 15:42 | <vagrantc> otavio: indeed!
| |
| 15:42 | hope i can get enough work in the next few months to stay a while
| |
| 15:44 | <otavio> vagrantc: I'll try to stay too. Dunno if it'll be possible or not. Let's see
| |
| 15:46 | Guaraldo has joined #ltsp | |
| 15:46 | mikkel has quit IRC | |
| 15:47 | <vagrantc> otavio: ok, calling add_fstab_entry by hand seems to get it mounted to /media/USERNAME/cdrom
| |
| 15:48 | otavio: and now, running it manually for floppy0 only gets as far as mounting to /tmp/.USERNAME-ltspfs/floppy0
| |
| 15:48 | so it seems the second mount is what causes it to fail
| |
| 15:48 | or, partially fail
| |
| 15:48 | <otavio> yes
| |
| 15:49 | but it's better since you can test it byhand now
| |
| 15:49 | primeministerp has quit IRC | |
| 15:50 | primeministerp has joined #ltsp | |
| 15:53 | <vagrantc> ok ... now i'm getting some error messages :))
| |
| 15:56 | "Error: can't bindmount under %s: already mounted\n",
| |
| 15:56 | in mkdir_safe
| |
| 15:56 | otavio: so it's trying to check if /media/USERNAME is mounted, and is_mounted is returning true ...
| |
| 15:57 | <otavio> yes.
| |
| 15:57 | and is it?
| |
| 15:57 | <vagrantc> no, but /media/USERNAME/FOO is mounted ... so something is prabably messed up there ...
| |
| 15:58 | Guaraldo has quit IRC | |
| 15:58 | <vagrantc> ah, it's probably my || (mode = "umount")
| |
| 15:58 | <otavio> and _whhy_ it doesn/ t use same media place? wasn't it suppose to be the same?
| |
| 15:58 | ahh ehhe
| |
| 15:59 | <vagrantc> otavio: well, lbmount needs to basically: mkdir /media/USERNAME, and then mkdir /media/USERNAME/DEVICE
| |
| 16:00 | Guaraldo has joined #ltsp | |
| 16:00 | <otavio> what I means is: why not in /tmp/.USERNAME-ltspfs/ too?
| |
| 16:02 | <vagrantc> because it causes debian bug 443200
| |
| 16:02 | otavio: oh...
| |
| 16:02 | otavio: ltspfsmounter handles /tmp/.USERNAME-ltspfs/*
| |
| 16:02 | otavio: that part can be handled in python as the user- lbmount is a setuid root binary.
| |
| 16:05 | ltspfsmounter can create /tmp/.USERNAME-ltspfs/, do the fuse mounts ... and then calls lbmount to "mount --move/--bind" into /media/USERNAME/
| |
| 16:05 | <otavio> yes
| |
| 16:05 | <vagrantc> did i answer your question, or do i not understand your question?
| |
| 16:08 | <otavio> I think you answered my question
| |
| 16:08 | <vagrantc> it would be a lot easier if we could just mkdir -p /media/USERNAME ; chmod g+w /media/USERNAME
| |
| 16:09 | then we can just mount directly to /media/USERNAME ... but people objected to that on the groups that someone could fill up / with files (where /media is most likely mounted)
| |
| 16:09 | <otavio> and why we can't?
| |
| 16:09 | ahh
| |
| 16:09 | <vagrantc> whereas, a good sysadmin will split /tmp off of /
| |
| 16:10 | <otavio> yes or leave it as tmpfs
| |
| 16:10 | <vagrantc> though, arguably, you could just as easily split /media off of / if you were worried
| |
| 16:11 | so i'm trying to do better than what we have now... and it's so close...
| |
| 16:12 | outofrange has left #ltsp | |
| 16:12 | <otavio> it should be a really stupid mistake
| |
| 16:13 | is floopy also being --bind?
| |
| 16:13 | <vagrantc> well, the current implementation uses --bind, but i'm trying to switch to using --move
| |
| 16:13 | because then only a single mount shows up
| |
| 16:14 | and it just looks nicer
| |
| 16:14 | :)
| |
| 16:15 | <otavio> yes
| |
| 16:16 | <vagrantc> it's a little confusing how "lbmount device" and "lbmount --umount device" are distinguished in the code...
| |
| 16:16 | big if statements
| |
| 16:16 | <otavio> it probably deserves a refactoring ;-)
| |
| 16:17 | staffencasa has quit IRC | |
| 16:18 | <vagrantc> otavio: i'm having a hard time not refactoring it... but i want to keep the diff understandable
| |
| 16:18 | <otavio> vagrantc: so invert it.
| |
| 16:18 | <vagrantc> ?
| |
| 16:18 | <otavio> vagrantc: refactor it and then go to your improvement .-)
| |
| 16:18 | <vagrantc> hmmm...
| |
| 16:22 | Guaraldo has quit IRC | |
| 16:23 | ltsp has quit IRC | |
| 16:26 | <vagrantc> otavio: ok, so i switched back to the single-line patch
| |
| 16:27 | well, still patched ltspfsmounter
| |
| 16:27 | but only the change from --bind to --move
| |
| 16:27 | in lbmount.c
| |
| 16:27 | works pretty good
| |
| 16:28 | but it leaves behind the /media/USERNAME/* directories
| |
| 16:31 | hmmm...
| |
| 16:44 | i think i have it
| |
| 16:44 | * vagrantc dances a bit | |
| 16:45 | jammcq has quit IRC | |
| 16:47 | <vagrantc> otavio: having worked on it all day, i just messed it up.

| 16:47 | otavio: but i started over and got it working :)

| 17:10 | <vagrantc> whew!
| |
| 17:15 | <otavio> works?
| |
| 17:15 | <vagrantc> otavio: seems to :)
| |
| 17:15 | <otavio> awesome!
| |
| 17:16 | <vagrantc> otavio: much less invasive patch than my previous attempts
| |
| 17:17 | <otavio> that's even better
| |
| 17:17 | <vagrantc> well, they're also not as good ... i.e. we're still using predictable paths in /tmp
| |
| 17:18 | <otavio> vagrantc: but now you can improve it, step be step
| |
| 17:18 | <vagrantc> otavio: exactly
| |
| 17:18 | <otavio> vagrantc: that's the best way to work
| |
| 17:18 | <vagrantc> otavio: i woke up at 3am thinking about this, and have been working on it for 11-12 hours :)
| |
| 17:18 | otavio: eventually i decided i had to start over on the actual code, and poof, it was easy :)
| |
| 17:18 | <otavio> vagrantc: wow! this makes me remember Mexico! ;-)

| 17:19 | <vagrantc> the 1-line patch switching --bind to --move was really impressive ... that almost worked without change
| |
| 17:21 | so i switched back to that, and then tried to figure out what else was broken...

| 18:06 | <ari_stress> morning all :D
| |
| 18:33 | <aboo0ood> morning ari_stress
| |
| 18:34 | guys, i have a question about LTSP boot process
| |
| 18:35 | Does the client request the IP address of the server where the kernel resides, then requests the IP address of the application server ?
| |
| 18:35 | 2 requests ?
| |
| 18:36 | <ari_stress> what is application server?
| |
| 18:37 | <aboo0ood> ari_stress, i mean the server where the chroot environment resides
| |
| 18:37 | <ari_stress> oh
| |
| 18:37 | as far as i know it only request the kernel
| |
| 18:38 | <aboo0ood> http://en.wikipedia.org/wiki/Linux_Terminal_Server_Project
| |
| 18:38 | ari_stress, look at this
| |
| 18:38 | it says there'a a (new) DHCP request after the first one
| |
| 18:38 | <ari_stress> we can specify the X server and log server to on another ip
| |
| 18:38 | <vagrantc> typically, you get one DHCP request for the bootloader, and one DHCP request from the initramfs whre to mount it's root filesystem
| |
| 18:40 | <aboo0ood> thanx guys :)
| |
| 18:41 | Q-FUNK has joined #ltsp | |
| 18:41 | <ari_stress> aboo0ood: you can see the details in lts-parameter.gz
| |
| 18:46 | spectra has quit IRC | |
| 18:47 | <aboo0ood> vagrantc, when we say chroot environment we are talking about /opt/ltsp .. then we say that the client mounts its root filesystem, where does it mount it ?
| |
| 18:47 | <vagrantc> on "/"
| |
| 18:48 | <aboo0ood> vagrantc, what is the full path on the server ?
| |
| 18:48 | <vagrantc> typically, /opt/ltsp/ARCH
| |
| 18:48 | i.e. /opt/ltsp/i386
| |
| 18:48 | <aboo0ood> mmm
| |
| 18:48 | <vagrantc> the most common
| |
| 18:48 | <aboo0ood> i am lost
| |
| 18:48 | chroot env. is already there
| |
| 18:48 | why is it remounting it
| |
| 18:49 | ?
| |
| 18:49 | <vagrantc> already where?
| |
| 18:49 | <aboo0ood> /opt/ltsp/ARCH
| |
| 18:49 | <vagrantc> the thin-client does something kind of like this
| |
| 18:49 | :
| |
| 18:50 | mount -t nfs 192.168.1.255:/opt/ltsp/i386 /
| |
| 18:50 | er
| |
| 18:50 | .255 is a bad example
| |
| 18:50 | mount -t nfs 192.168.1.254:/opt/ltsp/i386 /
| |
| 18:50 | where 192.168.1.254 is the ip address of the server
| |
| 18:50 | <aboo0ood> aha
| |
| 18:51 | it mounts something on the server .. on the server , right ?
| |
| 18:51 | <vagrantc> from the server
| |
| 18:51 | <aboo0ood> yes
| |
| 18:51 | <vagrantc> the server provides the files to the thin-client
| |
| 18:51 | <aboo0ood> and the thin-client mounts it on the server ? on "/" ? but where is this "/" relative to the root of the server ?
| |
| 18:54 | vagrantc, does it mount it back to /opt/ltsp/i386 ? which is "/" relative to the client ??
| |
| 19:04 | <vagrantc> aboo0ood: i really don't understand what you're asking.
| |
| 19:04 | it mounts it at "/", just like you would typically mount a hard drive at "/"
| |
| 19:05 | instead of /dev/hda1 or whatever, you have 192.168.1.254:/opt/ltsp/i386
| |
| 19:05 | aboo0ood: i think you're trying to make this more complicated than it is
| |
| 19:05 | <aboo0ood> it looks to me like mount /dev/hda1 /dev/hda1 , that's why i am confused ..
| |
| 19:05 | <vagrantc> no.
| |
| 19:06 | <aboo0ood> since "/" is really the chroot evn. path
| |
| 19:06 | <vagrantc> it's mount -t FILESYSTEM DEVICE PATH
| |
| 19:06 | in the case of a hard disk, FILESYSTEM might be ext3, DEVICE might be /dev/hda1 and PATH is /
| |
| 19:07 | in the case of NFS Root, Filesystem is nfs, DEVICE is 192.168.1.254:/opt/ltsp/i386 and PATH is /
| |
| 19:07 | <aboo0ood> ok, let me ask it in another way
| |
| 19:08 | does issuing the mount command on the server (say manually ) works the same as when its issued by the client ?
| |
| 19:08 | work *
| |
| 19:10 | <vagrantc> i just don't understand your question.
| |
| 19:10 | <aboo0ood> mmm
| |
| 19:10 | <vagrantc> there are files on the server at /opt/ltsp/i386.
| |
| 19:10 | <aboo0ood> i think i got it :)
| |
| 19:10 | J45p3r has joined #ltsp | |
| 19:10 | <vagrantc> the thin-client mounts those files, and sees them as /
| |
| 19:10 | <aboo0ood> i was confused since this "/" resides in the end on the server
| |
| 19:11 | <vagrantc> the server is just a file server
| |
| 19:11 | aboo0ood: chroot /opt/ltsp/i386 will see the same "/" as the thin-client (for the most part)
| |
| 19:11 | they're just files, not magic beans
| |
| 19:12 | <aboo0ood> lol
| |
| 19:12 | vagrantc, thanx :)
| |
| 19:14 | <vagrantc> i guess i've just been doing this too long

| |
| 22:17 | <rjune_> mplayer
| |
| 22:17 | it's just an mpeg1 file
| |
| 22:17 | or maybe mpeg2
| |
| 22:17 | <RiXtEr> gotcha
| |
| 22:17 | <rjune_> still, should be most players
| |
| 22:18 | * RiXtEr is in dows | |
| 22:18 | <RiXtEr> win dows that is ;)
| |
| 22:18 | downloading that file at a blazing 17.5 KB/s
| |
| 22:19 | Much better than the 3-4 KB/s i was getting with my dialup
| |
| 22:19 | cellphone internet is great!
| |
| 22:25 | that looks fun.. what kinda heli is that and how much does it cost
| |
| 22:29 | <rjune_> heh
| |
| 22:29 | 5G6
| |
| 22:29 | it was a christmas present, they run about $130
| |
| 22:29 | http://www.bphobbies.com/ sells them
| |
| 22:30 | <RiXtEr> eh... too much for me i'd have it broken in about 10 mins
| |
| 22:30 | or less :)

| 22:31 | <rjune_> start with a Mosquito
| |
| 22:32 | or a cheap foamie
| |
| 22:32 | though this is a pretty robust heli, I had my worst crash today
| |
| 22:32 | fell out of the air at about 18'
| |
| 22:32 | <RiXtEr> did you 'total' it
| |
| 22:33 | <rjune_> nope
| |
| 22:34 | I did knock one of the gears off though
| |
| 22:34 | <RiXtEr> nice
| |
| 22:34 | ow
| |
| 22:34 | <rjune_> and bent the hell out of my landing gear
| |
| 22:34 | <RiXtEr> i'll bet
| |
| 22:34 | <rjune_> that tail you see isn't stock, the stock one looks like a truss
| |
| 22:34 | <RiXtEr> I see that in the picture
| |
| 22:35 | does it handle different with the tail you have?
| |
| 22:35 | <rjune_> currently the tail is a carbon fiber job we did as a proof of concept
| |
| 22:35 | yeah, the one currently on is about 2" at the end and about 1" towards the body
| |
| 22:36 | and it's covered in duct tape, so it's an actual fin instead of a skeleton
| |
| 22:36 | <RiXtEr> you build carbon fiber stuff ?
| |
| 22:36 | <rjune_> got rod from the hobby shop
| |
| 22:36 | <RiXtEr> ah
| |
| 22:36 | :)
| |
| 22:36 | <rjune_> cut it with a dremel and hot melt glued it together
| |
| 22:37 | we have a roughly seven minute video of me flying around earlier.
| |
| 22:37 | it ends by me falling out of the air
| |
| 22:38 | <RiXtEr> run out of rf range?
| |
| 22:38 | <rjune_> no, tried a manouvre that is outside my, or the helicopter's ability
| |
| 22:39 | <RiXtEr> barrel roll?"
| |
| 22:39 | <rjune_> heh, no sudden stop
| |
| 22:39 | see that rod with two weights up top?
| |
| 22:39 | that keeps you from stopping too quickly
| |
| 22:39 | you stop fast, you fall fast.
| |
| 22:40 | <RiXtEr> ah... i thought that was another propeler

| |
| 22:41 | it's called a flybar
| |
| 22:41 | the top blades are attached to it
| |
| 22:41 | <RiXtEr> i c
| |
| 22:41 | <rjune_> the weights tend to keep the top blades perpendicular to the shaft.
| |
| 22:42 | it provides stabilization
| |
| 22:42 | <RiXtEr> gonna change the subject.... when do you see beryl / compiz ran with ltsp :)
| |
| 22:42 | <rjune_> no clue
| |
| 22:42 | <RiXtEr> lol
| |
| 22:43 | should ask jim
| |
| 22:43 | <rjune_> probably
| |
| 22:43 | should I have another piece of cake?
| |
| 22:43 | Morgan made a My Melody cake for Jen's birthday
| |
| 22:44 | <RiXtEr> that'd be great... could you just see the x server running 20 clients with xgl .... WOW CPU USAGE!!
| |
| 22:44 | My Melody cake?
| |
| 22:44 | <rjune_> heh
| |
| 22:44 | yeah
