09:13 | <dmaran> anyone having issues of late with local devices besides me? They used to work and now it doesn't seem that the udev rules are firing in ltsp. The devices are partitioned with fat32 and are picked up by both windows and my Arch install. Ideas?
| |
09:14 | CAN-o-SPAM has joined #ltsp | |
09:15 | <dmaran> And they are picked up in the chroot. just seem to not be mounted. Followed this guide https://wiki.ubuntu.com/DebugLocalDev and was A-OK until I got to the part about the udev rules.
| |
09:19 | Belay my last about the udev rules. They are on the client shown as Vfat.

11:22 | <droalt> hello all
| |
11:23 | Gadi: you around?
| |
11:23 | was referred to you by a couple people in this channel yesterday. I have a question about rdesktop sound redirection with ltsp
| |
11:24 | anybody on?
| |
11:25 | droalt has left #ltsp | |
11:29 | slashdotfx has quit IRC | |
11:29 | droalt has joined #ltsp | |
11:29 | <droalt> hi guys
| |
11:30 | Gadi: I was referred to you by a couple guys yesterday, they said you are the man for rdesktop ltsp sound redirection
| |
11:31 | hanthana_ is now known as hanthana | |
11:31 | <droalt> hello hanthana
| |
11:32 | <hanthana> droalt: hi
| |
11:32 | slashdotfx has joined #ltsp | |
11:32 | <droalt> hi slash
| |
11:33 | <Gadi> droalt: hey - sorry - Im here but busy - Ill try to answer as quickly as possible
| |
11:33 | whats up?
| |
11:33 | <droalt> ok brief description of the issue
| |
11:34 | lucascoala has joined #ltsp | |
11:34 | <droalt> running ltsp on intrepid, modified lts.conf to run rdesktop to windows 2003 TS
| |
11:35 | everything works great except the ltsp clients have no sound in rdesktop
| |
11:35 | I have setup a test lab, consisting of two regular dell pc's to test before applying fix to production
| |
11:35 | so both have sound cards that work
| |
11:35 | <Gadi> do you have ldm on one SCREEN and rdesktop on another?
| |
11:35 | <droalt> and the ltsp server's sound works great when using rdesktop
| |
11:36 | <dmaran> Still at a loss with local devices. It is enabled in lts.conf, fuse group is same, followed the wiki page on ts-ing local dev's got to here: ssh -X -S /var/run/ldm_socket_vt7_192.168.0.254 192.168.0.254 "/usr/sbin/ltspfsmounter /tmp add"
| |
11:36 | thenI get this: "/dev/fuse not writable" -- This is with all devices I have tried.
| |
11:36 | <droalt> no, purely rdesktop
| |
11:36 | i'll put my lts.conf here
| |
11:36 | <Gadi> droalt: and is that how it will go into production?
| |
11:36 | <droalt> yes
| |
11:36 | <Gadi> easiest fix:
| |
11:37 | edit: /opt/ltsp/i386/usr/share/ltsp/screen.d/rdesktop
| |
11:37 | near the top of the shell script, but not the first line, add:
| |
11:37 | alkisg has joined #ltsp | |
11:37 | <Gadi> pkill pulseaudio
| |
11:38 | or, better,
| |
11:38 | <ogra> Gadi mean as always ...
| |
11:38 | <Gadi> pkill -9 pulseaudio
| |
11:38 | <ogra> killing poor daemons
| |
11:38 | <Gadi> and save
| |
11:38 | ogra will fill you in on the theory
| |
11:38 | ;)
| |
11:38 | <ogra> he could also just apt-get remove it and run ltsp-update-image ;)
| |
11:38 | <nubae1> instead of making the deamons nicer
| |
11:38 | :-)
| |
11:38 | <Gadi> oh, and be sure to add to your rdesktop options:
| |
11:38 | -r sound:local
| |
11:39 | <droalt> ty I will try it now
| |
11:40 | use -r sound:local or -r sound:local:alsa or does it matter?
| |
11:40 | <Gadi> it shouldn't matter
| |
11:40 | it should use alsa by default
| |
11:40 | <droalt> Ty again, you were right ogra and nubae, Gadi is the man
| |
11:41 | <Gadi> nah, if I were more the man, I would have all the right fixes for rdesktop merged upstream
| |
11:41 | so, folks don't need to hack around
| |
11:41 | but I simply cannot find the time
| |
11:41 | alkisg1 has joined #ltsp | |
11:41 | <Gadi> *sigh*
| |
11:42 | <droalt> I understand man, I understand
| |
11:42 | alkisg has quit IRC | |
11:42 | <droalt> I currently manage 3 large school networks and it's killing me
| |
11:42 | <Gadi> droalt: note: if you ever start using ldm and rdesktop on separate screens at the same time, this fix will kill sound in ldm
| |
11:43 | <droalt> ty for the note, I'll remember that
| |
11:43 | <Gadi> so, make a skull and crossbones note
| |
11:43 | <droalt> they love how you can't "escape" terminal services
| |
11:43 | <Gadi> hehe
| |
11:44 | <droalt> I just think it's nice because in the past, they had to log on locally to a windows/linux box and then ts automatically opened. they would get confused really easily
| |
11:44 | ok well my first text box didn't work
| |
11:44 | <Gadi> droalt: I forgot
| |
11:44 | after you edit
| |
11:45 | run: sudo ltsp-update-image
| |
11:45 | :)
| |
11:45 | <droalt> np :)
| |
11:46 | alkisg1 has quit IRC | |
11:52 | <droalt> it works gadi, ty very much again
| |
11:52 | <Gadi> my pleasure
| |
11:53 | <ogra> .oO(apt-get remove would still have been cleaner and survive upgrades)
| |
11:54 | japerry has quit IRC | |
11:54 | * Gadi didn't see ogra raise his hand | |
11:54 | <Gadi> :P
| |
11:55 | <ogra> heh
| |
11:56 | <droalt> lol
| |
11:57 | apt-get remove pulseaudio in the chroot?
| |
11:57 | <ogra> right
| |
11:57 | instead of killing it ...
| |
11:57 | the script you just edited would be overwritten if you would do a security upgrade
| |
11:57 | <droalt> interesting, might try that also
| |
11:58 | once I rebuild my test server with all my notes and write my howto
| |
11:58 | <ogra> Gadi, err ...
| |
11:58 | i *think* you could just use SOUND=False in lts.conf and not touch the chroot at all :P
| |
11:58 | <droalt> lol
| |
11:59 | <ogra> since only the ltsp-client initscript spawns pulse on the clients
| |
11:59 | and that only reacts on the SOUND variable
| |
11:59 | dmaran has left #ltsp | |
12:00 | <Gadi> I was going to try that, too
| |
12:00 | but I am in a rush
| |
12:00 | and know that pkill works
| |
12:00 | :)
| |
12:00 | <ogra> indeed
| |
12:00 | its an AXE ...
| |
12:00 | * ogra calls Gadi Eugene | |
12:03 | <droalt> lol
| |
12:03 | i made note of everything you guys said, and I will try each one
| |
12:04 | for the sound=false in lts.conf, is that for ldm?
| |
12:04 | <ogra> no, for the whole setup
| |
12:05 | an ltsp client basically runs two initscripts, one sets the client up, the other starts services ... (the second one would start ldm) ... both read the variables from lts.conf and act accordingly
| |
12:05 | <droalt> awesome
| |
12:06 | and I shouldn't need to rebuild the image after modifying lts.conf correct?\
| |
12:06 | pmatulis_ has joined #ltsp | |
12:06 | <ogra> exactly
| |
12:06 | and lts.conf can switch things on and off on a per client base
| |
12:06 | i.e. if you would switch one client to ldm you could turn sound back on
| |
12:07 | removing pulse or editing the script are both pretty global hacks
| |
12:07 | <droalt> my lts.conf
| |
12:07 | <Blinny> If fuse is a group provided by a distant NIS master, will that introduce localdev problems?
| |
12:07 | <droalt> [default] RDP_OPTIONS = "-a 16 -d crutcho -r sound:local:alsa" RDP_SERVER = 172.16.0.16 SCREEN_02 = rdesktop SOUND = false
| |
12:07 | <ogra> Blinny, likely if the goupid doesnt match the local one
| |
12:07 | <droalt> that pasted well lol
| |
12:07 | <ogra> !pastebot
| |
12:07 | <ltspbot> ogra: "pastebot" is The LTSP pastebot is at http://pastebot.ltsp.org. Please paste all text longer than a line or two to the pastebot, as it helps to reduce traffic in the channel. A link to the content will be pasted in the channel.
| |
12:08 | <Blinny> ogra: There isn't a fuse local group in /etc/group - just the one provided by NIS
| |
12:08 | <ogra> droalt, its easier to use our pastebot ;)
| |
12:08 | <droalt> [default]
| |
12:08 | <Blinny> ogra: However, the gid is the same on both boxes (obviously -- it's only one group)
| |
12:08 | <ogra> Blinny, /dev/fuse will have a group id
| |
12:08 | <droalt> RDP_OPTIONS = "-a 16 -d crutcho -r sound:local:alsa"
| |
12:08 | RDP_SERVER = 172.16.0.16
| |
12:08 | <Blinny> Ah!
| |
12:08 | alkisg has joined #ltsp | |
12:08 | <droalt> SCREEN_02 = rdesktop
| |
12:08 | SOUND = false
| |
12:09 | <ogra> right, that should work
| |
12:09 | <droalt> cool
| |
12:09 | <ogra> if you would want a single client use ldm you would set:
| |
12:09 | <droalt> you see any problems running ltsp on a one nic setup instead of two
| |
12:09 | <ogra> [MACADDRSS]
| |
12:09 | SOUND=TRue
| |
12:09 | <droalt> cool
| |
12:09 | <Blinny> ogra: Are you talking about the owner/group perms of /dev/fuse? They're both root
| |
12:10 | <ogra> SCREEN_02=ldm
| |
12:10 | Blinny, that wont work, fusermount is sguid fuse
| |
12:11 | <Blinny> So I need to chgrp fuse /dev/fuse
| |
12:11 | Will that stick?
| |
12:11 | <ogra> no
| |
12:11 | its usually set by udev
| |
12:11 | Lns has joined #ltsp | |
12:11 | <ogra> you would need to hack up the udev rules ofr fuse
| |
12:12 | <Blinny> In /etc/udev/rules.d/45-fuse.rules ?
| |
12:13 | Damn. Appointment is here. Thanks for the info ogra. I'll bug you (or others in the channel) later.
| |
12:13 | <ogra> yeah, i have to go too
| |
12:13 | <droalt> ty ogra for your help
| |
12:13 | <ogra> (two days of constant pre-release install tests are exhausting)
| |
12:13 | <droalt> lol
| |
12:14 | pmatulis has quit IRC | |
12:14 | <droalt> pre-release of what?
| |
12:14 | <ogra> ubuntu
| |
12:14 | <droalt> so you're a developer for ubuntu?
| |
12:14 | <ogra> yes
| |
12:14 | <droalt> cool
| |
12:15 | i have a ubuntu issue with my laptop, but I'll save it for #ltsp
| |
12:15 | i mean #ubuntu
| |
12:15 | <ogra> (we have our next release on thu and all images need to be testinstalled)
| |
12:16 | <droalt> cool
| |
12:16 | japerry has joined #ltsp | |
12:16 | <ogra> well, rather tiring :)
| |
12:16 | <droalt> yea i bet
| |
12:16 | you have around 10 images right?
| |
12:17 | <ogra> http://iso.qa.ubuntu.com/qatracker/build/all/all
| |
12:17 | <droalt> whoa
| |
12:17 | <ogra> the numbers are the testcases per image
| |
12:18 | <droalt> 45ish
| |
12:18 | slashdotfx has quit IRC | |
12:18 | slashdot1x has joined #ltsp | |
12:18 | <ogra> or rather the different install methods that need testing
| |
12:18 | <droalt> wow
| |
12:18 | <ogra> well, 45images but look for example at the server image ... it has 15 install variants
| |
12:18 | <droalt> yup, i see that
| |
12:19 | did you test them all?
| |
12:19 | <ogra> or alternate ... has 9
| |
12:19 | (one of tehm is LTSP :) )
| |
12:19 | <droalt> yes edubuntu
| |
12:19 | will edubuntu work with a single nic setup?
| |
12:19 | <ogra> no, only the ones i built or am responsible for through my team
| |
12:19 | edubuntu turned into an addon CD
| |
12:19 | ltsp is on the actual ubuntu CD
| |
12:20 | <droalt> yes i know
| |
12:20 | i did a regular install of intrepid
| |
12:20 | built everything and set it up that way, with a single nic
| |
12:20 | i'd like to try edubuntu but don't want to break things
| |
12:20 | <ogra> but yes, ubuntu LTSP will work with a single NIC, you need to change some settings manually though, but the installer tells you what
| |
12:20 | <droalt> yes, my single nic setup is working, just not sure if I add the edubuntu addons if it will break anything
| |
12:21 | <ogra> edubuntu is only different artwork and a set of edu apps nowadays
| |
12:21 | <droalt> lunch is calling.....lol
| |
12:21 | cool
| |
12:21 | <ogra> ciao
| |
12:21 | <droalt> ty for the info
| |
12:21 | <ogra> enjoy your lunch
| |
12:22 | <droalt> i will and i will be back
| |
12:22 | i like to stay in here and help if I can, still new to ltsp though
| |
12:22 | btw
| |
12:22 | <ogra> we all were once :)
| |
12:22 | <droalt> the sound=false worked like a champ
| |
12:22 | ok lunch lol
| |
12:22 | <ogra> right, thats what i thought
| |
12:25 | nubae1 is now known as Nubae | |
12:28 | CAN-o-LUNCH is now known as CAN-o-SPAM | |
12:28 | <Blinny> I see an old post from Scott about adding , MODE="0666" to 45-fuse.rules - we allow localdevs for everyone.. does this sort the issue?
| |
12:34 | <zamba> my setup is as follows.. i want to use identical setup on all computers in my network.. but computers are often set up in "islands" where three or four computers share the same printer that's connected by usb or lpt to either of them.. in addition to this we have some computer labs where all the computers there share the same network attached printer.. is ltsp flexible enough to support this setup?
| |
12:35 | <Nubae> zamba: sure
| |
12:35 | <zamba> Nubae: how is this accomplished?
| |
12:35 | <Nubae> u can print on the server or to any printer connected to a thin client
| |
12:35 | using jetpipe
| |
12:36 | <zamba> Nubae: but i guess i need some individual configuration files for the different computers that tells them which printer to use?
| |
12:36 | <Nubae> right...
| |
12:36 | lts.conf is your friend
| |
12:36 | <zamba> cool
| |
12:36 | so it's possible.. that's all i need to know :)
| |
12:36 | <Nubae> check the docs for more info
| |
12:36 | !docs
| |
12:36 | <ltspbot> Nubae: "docs" is For the most current documentation, see http://wiki.ltsp.org/twiki/bin/view/Ltsp/LtspDocumentationUpstream
| |
12:36 | <zamba> yup
| |
12:38 | Blinny has quit IRC | |
12:39 | <Lns> zamba: you should only have to configure the printer once, on the server (ala lts.conf and in cups) and the clients should "just see it"
| |
12:40 | alkisg has quit IRC | |
12:40 | alkisg has joined #ltsp | |
12:40 | <zamba> Lns: well, the printer is connected to one of the diskless clients over lpt/usb
| |
12:40 | <Lns> zamba: right
| |
12:40 | <zamba> so i can't add something that's not there.. ?
| |
12:41 | <Lns> zamba: you want to configure lts.conf with the required parms to get a "network printer" via jetpipe to the client
| |
12:41 | <zamba> Lns: ok
| |
12:41 | <Lns> set up the ltsp server's CUPS to point to it after you've rebooted the client
| |
12:41 | <zamba> ok
| |
12:41 | <Lns> from my experiences anyway, all the clients will see it once it's set up on the server, regardless of physically which machine it's attached to
| |
12:42 | as long as you've configured everything right
| |
12:42 | <zamba> and then i have to set up stuff in lts.conf to define which printer should be the default for which system?
| |
12:42 | <Lns> no...afaik you set default printer on the server only
| |
12:42 | <Nubae> zamba: in lts.conf define each client using the mac address
| |
12:42 | so u'd have [mad:add:ress:one]
| |
12:42 | and so on
| |
12:43 | Frestechcoor has joined #ltsp | |
12:43 | <Nubae> under that put in the settings from the docs
| |
12:43 | <zamba> Nubae: yup.. and under each of those sections i can define stuff like default printer and so on?
| |
12:43 | yup
| |
12:43 | <Nubae> right
| |
12:43 | <zamba> cool
| |
12:43 | <Nubae> well if u want default put that under [default]
| |
12:43 | <Lns> Nubae: are there lts.conf options for default printer?
| |
12:43 | <zamba> well.. depending on location the different thin clients should have different default printers
| |
12:44 | each user shouldn't have to go through a list of 10+ printers to find the one located right next to him
| |
12:44 | so i'm dependant on that i can set a default printer for individual computer
| |
12:44 | computers*
| |
12:45 | <Lns> All I see in docs is PRINTER_0_DEVICE, PRINTER_0_PORT
| |
12:45 | which is for the locally attached printer
| |
12:45 | I'd have to assume at user-level config you can change your default printer, though i've never actually done that
| |
12:46 | i always set up printers with my own account and it just reflects on everyone else's
| |
12:47 | <zamba> yup.. but my setup is using the same user account for every user, but in different locations
| |
12:49 | <Lns> zamba: i don't know if that's a good idea. Bad things happen when you use the same user account for multiple workstations at the same time.
| |
12:49 | <Gadi> zamba: try in lts.conf: CLIENT_ENV = "PRINTER=<queue>"
| |
12:49 | <zamba> Lns: i've done stuff to circumvent that
| |
12:49 | <Lns> Gadi: always with the hidden options! =)
| |
12:50 | <Gadi> that may work depending upon your version of ldm
| |
12:50 | <zamba> Lns: i have a nfs mounted /home, but a tmp folder mounted on-top of that with unionfs
| |
12:50 | <Gadi> in future versions, you can set: LDM_PRINTER_DEFAULT
| |
12:50 | <Lns> nooice
| |
12:50 | Gadi: what about per-user cups config?
| |
12:50 | wouldn't that work?
| |
12:51 | <Gadi> that would go by user
| |
12:51 | linux_any_1 has joined #ltsp | |
12:51 | <zamba> Lns: so every user only has the shared home directory as a "starting point" and everything they write back to it will be lost on the next reboot
| |
12:51 | <Gadi> he wants it to go by machine
| |
12:51 | <Lns> Gadi: oh, right
| |
12:51 | <Gadi> LTSP deals with machines
| |
12:51 | :)
| |
12:51 | <Lns> Gadi: bah =p
| |
12:52 | <zamba> do i need X on the server to run ltsp?
| |
12:52 | i know i need x libraries, but do i need a x server running on the server?
| |
12:52 | <Gadi> no
| |
12:52 | <zamba> cool
| |
12:53 | so when choosing distro for the server, it's ok to use ubuntu server version instead of the desktop version?
| |
12:53 | <Gadi> zamba: sure - but you need to install a desktop
| |
12:53 | like gnome, kde, etc
| |
12:53 | <zamba> Gadi: yup
| |
12:54 | <droalt> you guys think that ubuntu is the best distro for ltsp?
| |
12:55 | <zamba> droalt: i really have no idea which is
| |
12:55 | but i'm comfortable with debian/ubuntu, so i stick to that
| |
12:55 | <droalt> cool
| |
12:55 | i tried k12linux which runs fedora core 10 and I was not impressed
| |
12:55 | <zamba> or maybe i'll just run some virtualization on ubuntu server and then set up a guest os that does the ltsp stuff
| |
12:56 | Guest26620 has quit IRC | |
12:56 | <droalt> careful about virtualing ltsp, when I virtualized it with virtualbox, I had to switch back to using nfs
| |
12:56 | <zamba> i think i'll use xen
| |
12:56 | <droalt> you might still have the same issue
| |
12:56 | of course switching to nfs is very easy
| |
12:57 | <zamba> but nfs instead of?
| |
12:57 | cifs?
| |
12:57 | <Lns> zamba: nbd
| |
12:58 | who was talking about ata over ethernet though last week...that sounded interesting
| |
12:59 | <droalt> something like, instead of having drives in a workstation, you have a drive controller that does ata over ip to a server?
| |
12:59 | cool, found a wiki about it
| |
12:59 | AoE
| |
13:00 | in wow terms, that means Area over enemy lol
| |
13:00 | alkisg has quit IRC | |
13:00 | <droalt> oh cool
| |
13:00 | instead of pxe booting
| |
13:00 | would nfs boot or AoE boot lol
| |
13:01 | <zamba> maybe i'll just run ltsp on the host then
| |
13:01 | what are the requirements on the workstations? are there any requirements at all?
| |
13:01 | it should have a mouse and keyboard and display adapter?
| |
13:02 | oh yeah, and a network card
| |
13:03 | <Lns> zamba: =p yes, there are some requirements
| |
13:03 | most here would recommend at least 128mb RAM, a 100mbit nic, 8+ mb vidram
| |
13:04 | petre has quit IRC | |
13:04 | <Lns> PII/PIII + cpu at least for newer ltsps
| |
13:04 | <zamba> Lns: ok
| |
13:04 | <Lns> depending on if you want other features (localdev/localapps comes to mind) you'll want more ram/cpu
| |
13:04 | just depends
| |
13:05 | <zamba> which a local app you'll need a disk drive, right?
| |
13:05 | eh
| |
13:05 | with*
| |
13:05 | <Lns> no
| |
13:06 | alkisg has joined #ltsp | |
13:09 | <zamba> hm, ok
| |
13:10 | <Frestechcoor> is there a brand of nic that works better for pxe booting?
| |
13:10 | <droalt> i don't think so
| |
13:10 | <Lns> Frestechcoor: shouldn't matter as long as the function is there
| |
13:11 | <droalt> I've had the best luck with intel onboard nics
| |
13:11 | <Lns> and isn't some insanely old version
| |
13:11 | realtek seems to work well too
| |
13:11 | <droalt> yup, anything that uses generic drivers
| |
13:11 | <zamba> dell computers work ok too
| |
13:12 | <droalt> yup, most of them have broadcom
| |
13:12 | <zamba> yup
| |
13:12 | <droalt> Frestechcoor: you having to buy nics?
| |
13:12 | <zamba> but if you have a nic that doesn't support PXE you have to do some magic with floppy booting first to get the network up, right?
| |
13:12 | <droalt> if so, these are cheap and work like a champ, d-link530tx+
| |
13:12 | <Lns> i've had some weirdnesses with broadcom - mainly taking a long time to process an initial dhcp reply during boot
| |
13:13 | <Frestechcoor> Probably I am looking into getting a lab setup at an elementary school using some old p II&III machines we have
| |
13:13 | <droalt> zamba: yes, or install a local image, or purchase a pxe nic
| |
13:13 | <Frestechcoor> Not all of them have nic's
| |
13:13 | <droalt> Frestechoor: do the motherboards have the pxe boot options?
| |
13:14 | Lns: yes thats on my to do list, some clients using broadcom won't pxe boot, dhcp times out
| |
13:15 | <Frestechcoor> nope. I used a thinstation boot cd, which then tells the computer to boot off the nic. I have 5 or so machines working now.
| |
13:15 | <droalt> cool
| |
13:15 | yes, without a doubt, try out the dlink530tx+
| |
13:15 | they might cost $1 more than a off brand but they work
| |
13:15 | they work in windows, linux, and macs
| |
13:16 | <Frestechcoor> thanks
| |
13:17 | <droalt> you're welcome
| |
13:17 | also if you go with an offbrand, like Lns said, make sure they have a realtek chip
| |
13:18 | woooo meeting time
| |
13:26 | <zamba> does ltsp-build-client use the apt cache when retrieving packages?
| |
13:28 | and i'm running a 64-bit os.. but i need to build clients for 386.. will this work?
| |
13:28 | doing a 'ltsp-build-client' without options will create /opt/ltsp/amd64
| |
13:28 | <Lns> zamba: man ltsp-build-client :)
| |
13:28 | <zamba> hehe
| |
13:29 | --arch and --dist i guess ;)
| |
13:29 | <Lns> there ya go
| |
13:29 | <zamba> well, not exactly
| |
13:30 | http://pastebin.com/m2a804683
| |
13:31 | (server is running hardy)
| |
13:33 | this is probably due to the fact that hardy is older than intrepid and thus "doesn't know" about it?
| |
13:35 | <Lns> zamba: why do you want a different chroot than what's on the server?
| |
13:36 | <zamba> Lns: because the server should be used for other things as well.. and i want the latest stable server with LTS
| |
13:36 | whereas the desktop clients should be "cutting edge"
| |
13:36 | thin clients, that is
| |
13:36 | <Lns> zamba: afaik it's generally and highly recommended that you use the same chroot as the server. different kernels and other software will have conflicts unless you really know what you're doing to fix it all up
| |
13:37 | in other words, you're not going to get intrepid features on the client side if you're running hardy on the server fs and an ibex chroot
| |
13:37 | at least not how you think
| |
13:37 | <zamba> hm..
| |
13:37 | <Lns> i might be wrong, but i remember hearing that before
| |
13:38 | for instance - xserver version FOO in chroot might have many issues with x clients / libs on server with version BAR
| |
13:38 | <zamba> if i was able to virtualize it effectively, i'd just set up a guest computer as intrepid
| |
13:42 | twinprism_ has joined #ltsp | |
13:46 | yoshi has joined #ltsp | |
13:47 | <alkisg> zamba, the chroot only has an x-server, you can't get e.g. openoffice 3 if you have a jaunty chroot in a hardy server. Or are you going to use fat clients?
| |
13:47 | yoshi is now known as Guest194 | |
13:54 | <zamba> alkisg: thin clients
| |
13:55 | <alkisg> zamba: so you don't need a different chroot, because it doesn't contain any "cutting edge" programs (other than a kernel and an x-server)
| |
13:58 | Frestechcoor has quit IRC | |
13:58 | <zamba> alkisg: so in other words.. if i want to run intrepid on the thin clients, i have to run the same on the server?
| |
13:58 | <Lns> zamba: the thin clients are running all applications FROM the server.
| |
13:58 | <alkisg> Yes
| |
13:59 | <zamba> i thought it was a bit more "virtualization" and "chroot"-ing to it
| |
13:59 | <alkisg> (unless you use fat clients, or some virtualization platform etc)
| |
13:59 | <zamba> i see
| |
14:04 | <Nubae> yeah u can use fatclient to serve a different image
