| 09:15 | with hundreds of media in there

| 10:28 | <joebaker> ogra_cmpc Hi, I've heard from sjoerd over in #pulseaudio that a problem with ekiga and pulseaudio is fixed in a recent release of libasound2-plugins.
| |
| 10:29 | It's reportedly working in debian as version 1.0.16-1
| |
| 10:30 | mccann has quit IRC | |
| 10:31 | <joebaker> I've not been able to get voip clients to run under Gutsy Edubuntu ltsp. I think the problem may be related to this bug:
| |
| 10:31 | https://bugs.launchpad.net/ubuntu/+source/alsa-plugins/+bug/112948
| |
| 10:32 | <ogra_cmpc> we dont have any capturing support in ltsp
| |
| 10:32 | so i would be surprised if ekiga worked
| |
| 10:32 | since its not expected to atm
| |
| 10:34 | <Gadi> ogra_cmpc: does pulse need to be configured for capture or just alsa on the client?
| |
| 10:34 | <ogra_cmpc> Gadi, pulse
| |
| 10:34 | the thing is that this needs detection mechanisms we dont have in place
| |
| 10:35 | pulses hal module would be a great enhancement here
| |
| 10:35 | but hal wont enter thin clients before itchy iguana
| |
| 10:35 | (in ubuntu at least)
| |
| 10:35 | i'm planning to add it though
| |
| 10:36 | staffencasa has joined #ltsp | |
| 10:36 | <Gadi> can it work at all without hal?
| |
| 10:36 | <ogra_cmpc> it does atm
| |
| 10:36 | you can set up a manual config
| |
| 10:36 | but need to know several things to add
| |
| 10:39 | <joebaker> atm ? (Asynchronous transfer mode? )
| |
| 10:39 | <ogra_cmpc> at the moment
| |
| 10:40 | <joebaker> :)
| |

| 10:41 | IRCMonkey has joined #ltsp | |
| 10:42 | <joebaker> Presently, I've installed the whole pulesaudio thing on my Ubuntu Gutsy Gibbons laptop. I'm experimenting with Asterisk and I can't use the voip clients because (I think) there's breakage in this libasound2-plugins. I'm thinking that if a version bump could be tried it might fix things on our thin clients also because we're running the same binaries there, right?
| |
| 10:43 | alekibango has quit IRC | |
| 10:46 | <IRCMonkey> I would like to run gimp on a distant computer through an ssh tunnel. When I do it on my computer it doesn't work: far too slow. Would ltsp inprove that. The client side computer is a pentium 4, 1.5Gh, the server computer is a dual-core rather new.
| |
| 10:49 | <ogra_cmpc> yes
| |
| 10:52 | <IRCMonkey> ogra_cmpc: Is the answer for me?
| |
| 10:52 | <ogra_cmpc> yes :)
| |
| 10:53 | steph_ has quit IRC | |
| 10:55 | <IRCMonkey> ogra_cmpc: Is there a way, then, I could connect myself to the server, and, still being able to use the client computer independently when I would like to. I understood using ltsp would be incompatible with using the 'client', also as a stand alone computer.
| |
| 10:56 | <Gadi> IRCMonkey: you could have the client either boot as a diskless thin client or boot from a local hard drive - if that what u mean
| |
| 10:58 | if you are just talking about having the client boot into Linux and launching a single application (gimp) over the network from another box, I would recommend NX if ssh by itself doesnt do it for you
| |
| 10:58 | <IRCMonkey> Gadi: two interesting points
| |
| 10:59 | <Gadi> kinda depends on what ur looking for
| |
| 10:59 | LTSP is about running *everything* from the server
| |
| 10:59 | <IRCMonkey> Gadi: NX is still tunneled through ssh?
| |
| 10:59 | <Gadi> and pushing back just a display
| |
| 10:59 | yes
| |
| 10:59 | NX = ssh+ xproxy + caching
| |
| 10:59 | + clever trickery
| |
| 10:59 | <ogra_cmpc> but nowadays every ssh should work out of the box
| |
| 11:00 | <Gadi> but NX can be much faster than ssh alone
| |
| 11:00 | due to the caching and trickery
| |
| 11:00 | <ogra_cmpc> just try it: ssh -X <serverip> gimp
| |
| 11:00 | <Gadi> :)
| |
| 11:00 | <ogra_cmpc> that should start gimp on your current desktop
| |
| 11:01 | <IRCMonkey> ogra_cmpc: ssh works fine, but there is a problem, it is not fast enough for me to be able to use gimp, too slow.
| |
| 11:01 | <ogra_cmpc> ah, ok
| |
| 11:01 | that i misunderstood
| |
| 11:02 | alekibango has joined #ltsp | |
| 11:02 | <Gadi> IRCMonkey: are you on a LAN?
| |
| 11:02 | I mean both computers
| |
| 11:02 | <IRCMonkey> Gadi: yes
| |
| 11:03 | <Gadi> do you *need* to encrypt the traffic?
| |
| 11:03 | try this: ssh <serverip> DISPLAY=<local_computer_ip:0> gimp
| |
| 11:04 | <ogra_cmpc> i think you need sh -c and some quoting
| |
| 11:05 | indradg_ has quit IRC | |
| 11:05 | indradg_ has joined #ltsp | |
| 11:05 | <IRCMonkey> Gadi: need, maybe not, but I prefer not to get the habit of transfering non encrypted data. Also, it is a laptop (the client side), and I could use it from outer of the lan.
| |
| 11:07 | ssh <serverip> DISPLAY=<local_computer_ip:0> gimp; what is this manipulation about. However I am going to try.
| |
| 11:09 | <warren> Q-FUNK, I think you misunderstand the relationship between OLPC and Fedora.
| |
| 11:09 | DonSilver is now known as K_O-Gnom | |
| 11:10 | <Q-FUNK> warren: ?
| |
| 11:10 | <warren> Q-FUNK, Fedora only fixes things that someone bothers to work on, and the engineers Red Hat employees are relatively few in number and barely able to fix core things.
| |
| 11:10 | <IRCMonkey> Gadi: cannot open dispay (is the answer), but I'll try again later, after reading the related documentations.
| |
| 11:10 | <warren> Q-FUNK, OLPC occasionally forks a Fedora version and goes off on their own. The current OLPC version is based on Fedora 7
| |
| 11:11 | <ogra_cmpc> thats odd
| |
| 11:11 | <Gadi> IRCMonkey: you probably need to do an: xhost +
| |
| 11:11 | <ogra_cmpc> why dont they contribute dircetly ?
| |
| 11:11 | <Gadi> before that ssh call
| |
| 11:11 | <warren> ogra_cmpc, poor leadership
| |
| 11:11 | <ogra_cmpc> ah
| |
| 11:12 | <Q-FUNK> warren: I keep on hearing about people at debian, ubuntu and fedora who package whatever is found in the olpc git, instead of contributing to the upstream of whatever the XO uses. i'm sick of it.
| |
| 11:12 | <warren> Q-FUNK, that isn't true of Fedora at all since Fedora 7
| |
| 11:12 | Q-FUNK, Fedora-8 and Fedora-9 has whatever is upstream X
| |
| 11:12 | Q-FUNK, although Fedora 9 hasn't been able to build at all for a while
| |
| 11:13 | <Q-FUNK> warren: right, becuase you guys already enabled libpciaccess
| |
| 11:15 | mccann has joined #ltsp | |
| 11:19 | <Q-FUNK> warren: so actually, there are distros. and all these people are regrouping resources at their own distro.
| |
| 11:20 | <warren> Q-FUNK, Fedora is the upstream upon which several distros fork their own things from
| |
| 11:20 | Q-FUNK, RHEL is another fork of Fedora (although pretty much everything goes back to Fedora upstream by company policy)
| |
| 11:20 | <ogra_cmpc> the upstream for xorg ?
| |
| 11:21 | <warren> ogra_cmpc, what are you asking?
| |
| 11:21 | <ogra_cmpc> fedora is the upstream for xorg ?
| |
| 11:22 | <warren> ogra_cmpc, distros
| |
| 11:22 | <ogra_cmpc> Q-FUNK was complaining about the x driver, no?
| |
| 11:23 | (at least thats how i understood it)
| |
| 11:24 | <IRCMonkey> Gadi: cannot open display, in all cases, even after xhost + (as though he said 'access control disabled, clients can connect from any host'). However I'll dig furter in this direction, and try to learn some about NX.

| 11:25 | <cdealer> good afternoon! What do I need to be able to see the local hd
| |
| 11:25 | <Gadi> open the case!
| |
| 11:25 | mhterres has quit IRC | |
| 11:25 | <Gadi> lol
| |
| 11:25 | mhterres has joined #ltsp | |
| 11:25 | <Gadi> cmon - we can use a lil comic relief about now
| |
| 11:26 | <ogra_cmpc> you can also use an endoscopic camera :)
| |
| 11:26 | <cdealer> haha
| |
| 11:26 | * Gadi shudders - no pun intended | |
| 11:26 | <cdealer> good one guys ... what I need to access my local hd on the thin clients ;)
| |
| 11:27 | <Gadi> cdealer: cat /opt/ltsp/i386/etc/udev/rules.d/88-ltsp*

| 11:29 | <Gadi> cdealer: ?
| |
| 11:29 | * Gadi taps the mic | |
| 11:29 | <cdealer> Gadi, im trying to figure out ... (trying...)
| |
| 11:29 | Gadi, want to see the output
| |
| 11:29 | <Gadi> sure
| |
| 11:30 | <cdealer> can I paste the 3 lines here
| |
| 11:30 | <Gadi> go ahead
| |
| 11:30 | I wont tell anyone
| |
| 11:30 | <cdealer> ACTION=="add", KERNEL=="fd[0-9]", RUN+="add_fstab_entry %k auto"
| |
| 11:30 | ACTION=="add", SUBSYSTEM=="block", ENV{ID_FS_TYPE}=="?*", RUN+="add_fstab_entry %k $ENV{ID_FS_TYPE}"
| |
| 11:30 | ACTION=="remove", SUBSYSTEM=="block", RUN+="remove_fstab_entry %k"
| |
| 11:30 | * Gadi bets ur local hdd is NTFS | |
| 11:30 | <Q-FUNK> ogra_cmpc: mainly that olpc people often act as if the whole geode universe was them and only them.
| |
| 11:30 | <cdealer> yeah.. it is
| |
| 11:30 | <Gadi> so, thats where the issue lies
| |
| 11:31 | adding NTFS support to the chroot
| |
| 11:31 | <cdealer> ntfs-3g
| |
| 11:31 | <Gadi> do you need read-write access?
| |
| 11:31 | or just read-only?
| |
| 11:31 | <cdealer> just read
| |
| 11:31 | <Gadi> even easier
| |
| 11:31 | add: MODULES_01 = ntfs
| |
| 11:31 | to your lts.conf
| |
| 11:31 | and reboot
| |
| 11:31 | <cdealer> Hmmmm
| |
| 11:31 | goooood ... thanks
| |
| 11:32 | <Gadi> if that doesnt work, then do this:
| |
| 11:32 | echo "ntfs" >> /opt/ltsp/i386/etc/modules
| |
| 11:32 | ltsp-update-image
| |
| 11:32 | <Q-FUNK> ogra_cmpc: the most recent exemple of that is the upgrade needed by all X drivers to support libpciaccess. olpc's main X guy decided to perform that on their old deprecated fork, rather than against upstream git.
| |
| 11:32 | <ogra_cmpc> oh sigh
| |
| 11:32 | <cdealer> Gadi, okay =)
| |
| 11:34 | <Gadi> ogra_cmpc: guess which company is paying to fix that for upstream
| |
| 11:34 | :)
| |
| 11:34 | <Q-FUNK> ogra_cmpc: when I pointed this out to him, he came back with "well, I used my own personal last known good copy of git".
| |
| 11:34 | <ogra_cmpc> Gadi, but it already is fixed in some wird fork and you could save half your money :P
| |
| 11:35 | isnt that sad ?
| |
| 11:35 | <Gadi> very
| |
| 11:35 | <Q-FUNK> ogra_cmpc: and wasting time trying to frontport this against a more recent upstream would be worth it?
| |
| 11:35 | <Gadi> but, here at Symbio, we look past the mountains, the hurdles, the obstacles in our way....
| |
| 11:36 | <ogra_cmpc> Q-FUNK, no, if the fixer would check in to the right source would ...
| |
| 11:36 | <Gadi> if it means that just one more child can get just one more laptop that much sooner, we applaud our OLPC friends
| |
| 11:36 | <Q-FUNK> ogra_cmpc: that guy was already told several time to drop their own fork and to submit patches to upstream. he simply doesn't care.
| |
| 11:37 | <Gadi> cant we all just think of the children
| |
| 11:37 | * ogra_cmpc slaps Gadi out of that TV show mode | |
| 11:37 | andarilho has joined #ltsp | |

| 11:38 | <Q-FUNK> HEY! you forgot the kittens! just think of all the kittens!
| |
| 11:38 | <ogra_cmpc> heh
| |
| 11:38 | and puppys
| |
| 11:39 | * Gadi thinks they were eaten by Sally Struthers | |
| 11:40 | * Guaraldo thinks about puppys eating kittens... :-P | |
| 11:41 | <Q-FUNK> I saw tons of pretty cool LX800-based gear at Embedded World, in Nürnberg. meanwhile, exactly one OLPC in the whole show. dead. in a glass case.
| |
| 11:41 | <Gadi> was there a child in there - I hope?
| |
| 11:42 | <warren> hah
| |
| 11:42 | vagrantc has joined #ltsp | |
| 11:42 | <warren> Gadi, yes, even a more expensive American demo child.
| |
| 11:42 | <Gadi> made by intel, no doubt
| |
| 11:43 | along with a sony robot dog
| |
| 11:44 | <cdealer> Gadi, local hd isnt mouting... I have already done the two things you mentioned...
| |
| 11:44 | <Q-FUNK> I, for one, welcome our OLPC worshipping Aibo overlords.
| |
| 11:44 | <cdealer> Gadi, I dont know to update kernel ?
| |
| 11:45 | *know=need
| |
| 11:46 | <Gadi> cdealer: you on gutsy?
| |
| 11:46 | <cdealer> yes
| |
| 11:46 | <Gadi> then, you shouldnt need to
| |
| 11:46 | hmm...
| |
| 11:46 | can you get a shell on the client?
| |
| 11:47 | <cdealer> sure.. will only need a reboot...
| |
| 11:47 | <Gadi> do it man, and do it with conviction
| |
| 11:48 | btw , cdealer, you don't actually deal crack, do you?
| |
| 11:48 | * Gadi guesses thats OT | |
| 11:48 | <Gadi> nm
| |
| 11:49 | just thinkin of the children
| |
| 11:49 | in the glass case, God bless em
| |
| 11:49 | well, only one I suppose
| |
| 11:49 | with a dead laptop
| |
| 11:49 | how sad
| |
| 11:50 | <cdealer> Gadi, no no ... it have to do with computers not drugs ;)
| |
| 11:50 | Gadi, ok, I have a shell on the client now
| |
| 11:50 | <Gadi> ok - type: grep ntfs /proc/filesystems
| |
| 11:51 | <cdealer> Gadi, show " ntfs"
| |
| 11:52 | <Gadi> excellent
| |
| 11:52 | now, ls /var/run/drives
| |
| 11:52 | IRCMonkey has left #ltsp | |
| 11:54 | <cdealer> Gadi, I had inside atadisk-hda1 atadisk-hda5 disk floppy ... all empty
| |
| 11:54 | <Gadi> beautiful
| |
| 11:54 | ok, 1 sec while I check something
| |
| 11:55 | ok, grep hda1 /var/run/ltspfs_fstab
| |
| 11:56 | plamengr has joined #ltsp | |
| 11:58 | <cdealer> Gadi, /dev/hda1 /var/run/drives/atadisk-hda1 ntfs defaults,iocharset=utf8 0 0
| |
| 12:01 | <Gadi> looks like its working
| |
| 12:01 | lets check one more thing
| |
| 12:01 | mount /dev/hda1 /mnt
| |
| 12:01 | ls /mnt
| |
| 12:04 | <cdealer> Gadi, ok, its mounted inside /mnt
| |
| 12:04 | <Gadi> ok umount /mnt
| |
| 12:05 | grep ssh /usr/share/ldm/rc.d/S10-delayed-mounter
| |
| 12:06 | make sure it says: ssh -X ....
| |
| 12:07 | <vagrantc> cdealer: what linux distro is this on? is it mounting other devices?
| |
| 12:07 | <Gadi> if all of that is good, it should work - you should see about 4 drives when you log in thru ldm
| |
| 12:07 | vagrantc: he's on gutsy
| |
| 12:07 | <cdealer> vagrantc, gutsy .. everything is mounting ...
| |
| 12:08 | <vagrantc> what's the first device in /var/run/ltspfs_fstab ?
| |
| 12:08 | <Gadi> and he's not a crack dealer - allegedly
| |
| 12:08 | <cdealer> yeah ..im not
| |
| 12:08 | =)
| |
| 12:08 | <vagrantc> cdealer: as in... it's working now?
| |

| |
| 12:11 | so the local hard-drive is, or is not, mounted?
| |
| 12:11 | maybe i should just back out now :)
| |
| 12:11 | <Gadi> you know you cant look away now
| |
| 12:11 | ur in too deep
| |
| 12:11 | you need to know how it ends
| |
| 12:12 | <vagrantc> i haven't even figured anything out yet
| |
| 12:12 | like, what the issue is
| |
| 12:12 | <Gadi> thats right where we want you to be
| |
| 12:12 | always asking
| |
| 12:12 | <vagrantc> well, off i go :)
| |
| 12:12 | <Gadi> never knowing
| |
| 12:12 | <vagrantc> got things to do.
| |
| 12:12 | <Gadi> is it all it appears to be?
| |
| 12:12 | <cdealer> vagrantc, everything but hd is not

| 12:15 | <cdealer> Gadi, sorry, this means to disable the shell and reboot to get only ldm?
| |
| 12:16 | Egyptian[Home] has joined #ltsp | |
| 12:16 | <Gadi> yes (or alternatively, put SCREEN_07=ldm and SCREEN_02=shell in your lts.conf so you can switch)
| |
| 12:17 | <warren> if you use SCREEN_02 anything you have to turn off mingetty on that tty right?
| |
| 12:18 | <cdealer> Gadi, thats already, if I switch to ldm i cant see any hd mounted... will reboot and try again ...
| |
| 12:19 | cyberorg has joined #ltsp | |
| 12:20 | <Gadi> warren: on gutsy chroot there's only a getty on tty1
| |
| 12:20 | but, in general, yes
| |
| 12:21 | <warren> Gadi, does plain debian have only tty1?
| |
| 12:21 | <Gadi> cdealer: tell me all the local drives that you see when you go in thru ldm
| |
| 12:21 | <warren> debian/ubuntu
| |
| 12:21 | <Gadi> no, but the chroot does
| |
| 12:21 | its one of the ltsp-build-client plugins
| |
| 12:21 | <warren> hm.... I suppose I should gimp my chroot as well
| |
| 12:21 | Gadi, which?
| |
| 12:21 | * Gadi looks | |
| 12:21 | <warren> I just realized the other day, that gimp is a very appropriate name.
| |
| 12:22 | gimp really sucks at what it does.
| |
| 12:22 | <Gadi> 010-cleanup-consoles
| |
| 12:22 | hey hey hey now
| |
| 12:22 | gimps dont suck
| |
| 12:22 | well, Im sure some do
| |
| 12:24 | <cdealer> Gadi, floppy and CDrom...
| |
| 12:25 | <Gadi> and you are sure those are the *client's* floppy and cdrom, yeah?
| |
| 12:25 | <ogra_cmpc> dont we all suck ? (if we are very young at least)
| |
| 12:25 | <Gadi> if you open a terminal window and do: ls /media/$USER
| |
| 12:25 | what do you get?
| |
| 12:26 | <cdealer> Gadi, I did on the server and have only floppy0
| |
| 12:28 | <Gadi> ah, so only the floppy is showing up, really
| |
| 12:28 | * Gadi recalls a bug that vagrantc mentioned with delayed mounter only doing the first item on the list.... | |
| 12:30 | <cdealer> Gadi, yeah... want me to insert a cd to see if it mounts

| 12:31 | subhodip__ is now known as tux_440volt | |
| 12:32 | <Gadi> sure
| |
| 12:33 | <warren> don't copy that floppy

| |
| 13:15 | <rcy> im trying to figure out how to organize multiple chroots with a single pxelinux.cfg/default file
| |
| 13:16 | <cliebow___> rcy:perhaps that dshould be done in inetd.conf..
| |
| 13:16 | <rcy> i recently did a ltsp-build-client --chroot testchroot, and it wound up overwriting i386/pxelinux.cfg/default
| |
| 13:16 | which was unexpected
| |
| 13:16 | cliebow___: in inetd.conf?
| |
| 13:19 | what i want to end up with is a netboot server that offers a menu of chroots to boot into
| |
| 13:20 | <Gadi> rcy build all chroots then edit the pxelinux.cfg/default file by hand
| |
| 13:20 | its just a matter of using the correct nbdport per entry
| |
| 13:21 | ltsp-update-kernels is the one updating the pxelinux.cfg/default file iirc
| |
| 13:21 | so, you could edit that out as well
| |
| 13:21 | <rcy> Gadi: ok. what surprised me is that stuff in /tftpboot/ltsp/i386 was disturbed
| |
| 13:21 | indradg has quit IRC | |
| 13:21 | <rcy> eventhough i specified a different chroot
| |
| 13:21 | <Gadi> it tries to do the right thing
| |
| 13:22 | <rcy> i guess i should move my custom pxelinux.cfg stuff right out of there
| |
| 13:22 | <Gadi> that is surprising
| |
| 13:22 | DonSilver has joined #ltsp | |
| 13:24 | <rcy> ltsp-update-kernels, thanks. ive been reading ltsp-build-client and the plugins directory, and not finding anything related
| |
| 13:26 | ah yeah. it seems ltsp-update-kernels doesnt care what chroot you are doing ltsp-build-chroot... it loops through all of them and updates
| |
| 13:28 | <Gadi> right - but I would have thought it would update: testchroot/pxelinux.fg/default
| |
| 13:29 | <rcy> Gadi: it does indeed update that one, along with my original chroot, which had a hacked /default file
| |
| 13:30 | ill move the non chroot specific boot stuff out of the chroot
| |
| 13:30 | mccann has quit IRC | |
| 13:31 | <Gadi> ah - and it is ltsp-update-image that does the pxelinuxcfg updating
| |
| 13:32 | <ogra_cmpc> make your edits in the chroots boot/ dir not in the tftp dir
| |
| 13:32 | then run ltsp-update-kernels and it will copy that in place
| |
| 13:33 | <rcy> ogra_cmpc: right, that makes sense
| |
| 13:33 | <Gadi> but, then you need a copy of the same pxelinux.cfg dir in each chroot
| |
| 13:33 | yeah, this can get kinda complicated
| |
| 13:33 | :)
| |
| 13:34 | I guess you only need to manage whichever image your dhcpd.conf points to
| |
| 13:34 | why so many images?
| |
| 13:35 | <rcy> im going to just maintain my own /var/lib/tftpboot/boot/pxelinuxcfg that will provide a default file with the menu that boots into the various chroots
| |
| 13:35 | <Gadi> there ya go
| |
| 13:36 | and edit the dhcpd.conf to point there
| |
| 13:36 | <rcy> yep
| |
| 13:36 | <Gadi> maybe cdealer == "chroot dealer"
| |

| 13:49 | andarilho has quit IRC | |
| 13:49 | <rcy> do you think ltsp-update-kernels should take a --chroot option, and be called with it when you do ltsp-build-client --chroot. my expectation is that if i am building or updating a particular chroot, my others wont be disturbed at all
| |
| 13:50 | andarilho has joined #ltsp | |
| 13:50 | <Gadi> rcy: it was actuall ltsp-update-image disturbing your pxelinux dir
| |
| 13:51 | ltsp-update-kernels just copies the kernels and innitrds
| |
| 13:51 | andarilho has left #ltsp | |
| 13:52 | <rcy> Gadi: hmm... ok, still finding my way around. ltsp-update-kernels does seem to cp $CHROOT/boot $TFTPBOOT/$CHROOT_NAME for all chroots
| |
| 13:52 | * rcy looks at ltsp-update-image | |
| 13:54 | <rcy> I dont have ltsp-update-image here. debian etch
| |
| 13:56 | I see it on my edubuntu system though
| |
| 13:56 | <cliebow___> must be old enough..to not have the squashfs
| |
| 13:57 | seems ogra has said as much beforew
| |
| 13:57 | <rcy> yeah, im using nfs on my debian ltsps
| |
| 14:02 | <vagrantc> rcy: we could use "cp -u" which won't change anything if it's unmodified
| |
| 14:02 | Bengoa has quit IRC | |
| 14:03 | <vagrantc> actually, that just uses time-stamps, which could get messy.
| |
| 14:04 | cliebow___: debian uses NFS by default even in the newest versions
| |
| 14:04 | cliebow___: requires manual configuration and possibly fixing bugs in other software to get the NBD+squashfs+unionfs on debian
| |
| 14:04 | <cliebow___> ok ..good to know!
| |
| 14:05 | all in good time..8~)
| |
| 14:05 | <vagrantc> rcy: how did ltsp-update-kernels mess up your configuration?
| |
| 14:06 | <rcy> vagrantc: i originally ran ltsp-build-client, which copied the kernel and pxelinux stuff to /var/lib/tftpboot/i386
| |
| 14:07 | <vagrantc> rcy: what behavior did ltsp-update-kernels do that you didn't want ?
| |
| 14:07 | <rcy> i edited pxelinux.cfg/default to provide a boot menu and added some memtest stuff, and a debian installer
| |
| 14:07 | <vagrantc> ah.
| |
| 14:07 | yes, i would recommend not using the auto-generated pxelinux.cfg stuff
| |
| 14:08 | <rcy> i discovered ltsp-build-image --chroot here the other day, and wanted to build a dummy chroot to muck around with
| |
| 14:08 | <vagrantc> just set up pxelinux.o and pxelinux.cfg in some other tftp dir
| |
| 14:08 | <rcy> and was surprised to find out that it stomped on my i386 stuff a bit
| |
| 14:08 | <vagrantc> ltsp-build-client ?
| |
| 14:08 | <rcy> sorry, i need to hack tab to complete from $PATH in my irc client :)
| |
| 14:09 | yeah ltsp-build-client
| |
| 14:09 | now that i get whats going on, yeah, yer right... putting my custom pxelinux boot menu stuff elsewhere is the right thing to do
| |
| 14:10 | <vagrantc> rcy: it's long been on my todo list to improve that ... but if you could file a wishlist bug, that would be appreciated
| |
| 14:10 | <rcy> however, im now wondering if making the ltsp update tools understand a system like that
| |
| 14:11 | <vagrantc> rcy: you could probably chain-load the pxelinux.0 's ... so set up your custom menu to chain-load the ltsp pxelinux.0 ...
| |
| 14:11 | <rcy> thats my next question... where do i send bugs/patches? its not clear where ltsp development is centralized, if it is at all. debian? ubuntu? ltsp.org?
| |
| 14:12 | steph__ has joined #ltsp | |
| 14:12 | <vagrantc> rcy: well, upstream is ltsp-developer@lists.sourceforge.net ... if you're using debian, i, as the debian maintainer, would appreciate bugs reported to the debian bug tracking system ... and if you're using ubuntu, they'd probably like bugs reported there
| |
| 14:12 | <rcy> i have both debian and ubuntu ltsp installations here
| |
| 14:12 | <vagrantc> rcy: ltsp5 is actually sort of decentralized development :)
| |
| 14:13 | <rcy> but the ubuntu one i pretty much leave alone
| |
| 14:13 | <vagrantc> rcy: and both ubuntu and debian communicate between one another
| |
| 14:13 | <rcy> all the weird stuff that im doing is happening on the debian ltsps
| |
| 14:13 | <vagrantc> rcy: actually, the ubuntu folks probably do a better job of following debian development
| |
| 14:15 | keeping up to date on launchpad is a bizzarre and confusing experience for me
| |
| 14:16 | steph_ has joined #ltsp | |
| 14:17 | <rcy> some/other/pxelinux.0 is something i can specify as a kernel in pxelinux.cfg/default?
| |
| 14:18 | foxxbuntu has joined #ltsp | |
| 14:19 | <rcy> that is much cleaner than doing all the cutting and pasting of im doing now to create a single menued default file
| |
| 14:20 | gonzaloaf_work has quit IRC | |
| 14:22 | <Gadi> rcy: no - just change your dhcpd.conf
| |
| 14:22 | to point to: /boot/pxelinux.0
| |
| 14:24 | gonzaloaf_work has joined #ltsp | |
| 14:28 | <rcy> im gonna rearrange everything now to look something like that.

| |
| 15:40 | <warren> where is it put to be made available to the OS?
| |

| |
| 15:41 | I don't have read/write /

| 16:32 | <keithclark> Hi everyone, I'm new to this terminal server project.
| |
| 16:34 | I was just wondering how exactly to get started.
| |
| 16:37 | <vagrantc> you want to install it?
| |
| 16:37 | what linux distro?
| |
| 16:40 | <keithclark> PCLinuxOS
| |
| 16:40 | And the terminals will be a mix of pclos and ubuntu
| |
| 16:40 | <vagrantc> well, ubuntu supports LTSP5 quite well. don't know anything about pclos
| |
| 16:41 | <keithclark> hmmmm
| |
| 16:41 | I'm working my way through the docs now....
| |
| 16:41 | <vagrantc> is pclos based on another distro?
| |
| 16:41 | <keithclark> Mandriva
| |
| 16:42 | Or it was anyways.
| |
| 16:42 | <vagrantc> no ltsp5 support on mandriva, i'm pretty sure.
| |
| 16:42 | <keithclark> That is too bad.
| |
| 16:43 | <vagrantc> you probably can install ltsp 4.x, but it hasn't seen updates in a couple years. a lot of people still use it though.
| |
| 16:43 | <keithclark> damn.....
| |
| 16:43 | I really just wanted a simple solution and this seemed to be it.
| |
| 16:43 | <vagrantc> you best bet for a current LTSP implementation is ubuntu or debian

| 23:23 | burnerx has joined #ltsp | |
| 23:24 | <warren> vagrantc, I dunno, I just guessed based upon what I saw in the script before
| |
| 23:24 | vagrantc, should we just rip it out?
| |
| 23:24 | vagrantc, how do you give it a predefined xorg.conf otherwise?
| |
| 23:26 | <vagrantc> warren: well, X_CONF is how we do that ... AH ... XFCFG is just where to copy *to*
| |
| 23:26 | i.e. /etc/X11/xorg.conf
| |
| 23:27 | <warren> vagrantc, perhaps we shouldn't let that be configurable
| |
| 23:27 | vagrantc, since it runs the X server with -config <path>
| |
| 23:27 | would you agree?
| |
| 23:27 | <vagrantc> i wouldn't want it to be configurable, but might be worth leaving as a variable if it's used multiple times in the script
| |
| 23:27 | <warren> vagrantc, how do you pass a different config file to the client chroot?
| |
| 23:28 | vagrantc, ok, i'll do that
| |
| 23:28 | I will explicitly unset it
| |
| 23:29 | then set if only if X_CONFIG is passed
| |
| 23:29 | vagrantc, what should the hard coded location be? /tmp/xorg.conf OK?
| |

| 23:31 | <warren> vagrantc, it is a huge pain for us distros with readonly-root
| |
| 23:31 | vagrantc, bind mounting a single file has lots of problems if you are copying things upon it or modifying it
| |
| 23:33 | vagrantc, /tmp/xorg.conf is guaranteed to be non-persistent and writable for everyone
| |
| 23:35 | pushed a revised version to ltsp-trunk
| |
| 23:36 | Now I must figure out how the heck I will handle screen_sessions
| |
| 23:36 | Fedora doesn't treat *DM sessions as a "service" like Debian
| |
| 23:36 | I guess each screen.d script has its own while loop for respawning...

| 23:52 | <warren> vagrantc, oh!!!
| |
| 23:52 | vagrantc, I'm going to use dhcp to tell my client where to get its lts.conf
| |
| 23:53 | but before I do that, I have to fix screen_session...
