| 00:37 | <antilyman> hey people happy new year
| |
| 00:39 | I'm in Madagascar and I don't have enough bandwidth, I would like to use my ltsp-server to update my ltsp-image
| |
| 00:39 | I'm on LUbuntu Maverick
| |
| 00:40 | when I do an update with aptitude on the server, it downloads everything that will be downloaded again when I chroot in the ltsp
| |
| 00:40 | so packets are downloaded twice
| |
| 00:41 | <muppis> antilyman, install apt-cacher and set it as proxy for both.
| |
| 00:42 | But you still need use same arch for both, otherwise no help from that.
| |
| 00:42 | <antilyman> they're on the same arch
| |
| 00:42 | it's ok
| |
| 00:42 | thank you
| |
| 00:42 | I was like installing apt-mirror
| |
| 00:45 | <muppis> apt-cacher is easier, because it doesn't need any sources.list. It acts as proxy, so you can use it all installations and have their own sources.
| |
| 00:46 | <antilyman> ok I catch it
| |
| 00:46 | <muppis> And apt-cacher doesn't use your network by own like apt-mirror does.

| 03:48 | <antilyman> it's me again
| |
| 03:48 | I'm running ltsp-server on ubuntu maverick
| |
| 03:48 | and I don't know since when my clients takes long time to boot
| |
| 03:49 | I'm still searching
| |
| 03:49 | but if anyone has any advice to narrow my searches
| |
| 03:49 | <Appiah> searching for what
| |
| 03:49 | <antilyman> for how to make the clients boot faster
| |
| 03:50 | <Appiah> where is the boot slow?
| |
| 03:50 | <antilyman> since the beginning
| |
| 03:50 | then it looks like hanging on "trying to load pxe.cfg/default"
| |
| 03:51 | but after few minutes it goes on loading vmlinuz
| |
| 03:51 | <Appiah> if it's slow already there i'd say its the network
| |
| 03:51 | <antilyman> wires ?
| |
| 03:51 | <Appiah> or the client
| |
| 03:51 | how many clients have this issue? all? some? just on 1?
| |
| 03:51 | <antilyman> the client was OK before (PII 350 with 164 Mb RAM)
| |
| 03:52 | <Appiah> 1
| |
| 03:52 | <antilyman> I tried to boot 2 clients
| |
| 03:52 | maybe t's the network
| |
| 03:54 | it's weird because I didn't do any changes
| |
| 03:54 | in network configuration
| |
| 03:54 | <Appiah> check the dhcp server for errors
| |
| 03:55 | maybe just a restart of the dhcpd will do?
| |
| 03:55 | is the server spitting out other errors?
| |
| 03:55 | <antilyman> already did
| |
| 03:55 | nothing special in daemon.log
| |
| 03:55 | <Appiah> dmesg, /var/log/messages ?
| |
| 03:56 | I dont think dhcpd logs in daemon.log default on ubuntu
| |
| 03:57 | <antilyman> seems like it's a network card problem
| |
| 03:57 | my card is a tulip
| |
| 03:58 | <Appiah> on the client or server?
| |
| 03:58 | <antilyman> on the server
| |
| 03:58 | and I've got a lot of : tulip_stop_rxtx() failed (CSR5 0xfc06c012 CSR6 0xff974111)
| |
| 03:58 | in dmesg
| |
| 03:58 | nothing special in /var/log/messages
| |
| 03:59 | I'll try to use another ethernet card
| |
| 04:01 | thank you
| |
| 04:01 | I'll install another ethernet card and test if it's better
| |
| 04:01 | see you

| 09:09 | <Dantix> hi all, I'm receiving this error: can't start hardware abstraction layer - please ensure dbus is running, but I can't figure out what runlevel is running my workstation to add the SXXdbus.
| |
| 09:13 | <Appiah> is this the client?
| |
| 09:13 | What dist are you running?
| |
| 09:16 | <Dantix> yes the client, Debian Lenny
| |
| 09:16 | robehend1 has joined #ltsp | |
| 09:16 | <robehend1> has anyone used IceWM as a desktop enviro for LTSP?
| |
| 09:19 | <Appiah> Dantix: weird , thought debian would add things like that automaticly
| |
| 09:19 | robehend1: read about people using other things then GNOME and KDE
| |
| 09:20 | using WM's instead of DE's
| |
| 09:20 | <robehend1> hmm, guess ill have to play with it.
| |
| 09:20 | <Appiah> search the mailinglist
| |
| 09:20 | <robehend1> will do
| |
| 09:21 | <Dantix> Appiah: yes, weird, I've just add the link en every rc folder and testing
| |
| 09:21 | alexqwesa has quit IRC | |
| 09:21 | <Appiah> Dantix: :D
| |
| 09:21 | alexqwesa has joined #ltsp | |
| 09:22 | <Appiah> robehend1: found one here saying they switched to IceWM and things went quicker
| |
| 09:22 | <robehend1> i'm hoping for quicker, as well as less overhead, as well as throwing a easy to use theme on there for my kindergarten
| |
| 09:22 | <Appiah> it's just a matter of making it start IceWM instead of gnome..
| |
| 09:22 | (should be)
| |
| 09:23 | <robehend1> yep. thats through init scripts, correct?
| |
| 09:23 | <knipwim> i'm using fluxbox on my ltsp-client by adding LDM_SESSION=/usr/bin/fluxbox to the lts.conf
| |
| 09:24 | cyberorg has quit IRC | |
| 09:24 | <Dantix> Appiah: before try with debian i've installed the ltsp that comes with ubuntu and the clients never boots, do you know about problems with ubuntu pacakges?
| |
| 09:24 | <Appiah> Dantix: 10.10 ?
| |
| 09:24 | vvinet has quit IRC | |
| 09:24 | cyberorg has joined #ltsp | |
| 09:24 | <Dantix> Appiah: yes
| |
| 09:25 | <robehend1> knipwim: thanks knipwim. does that still give people the option to go into gnome, or does it force them into fluxbox?
| |
| 09:25 | vvinet has joined #ltsp | |
| 09:25 | <knipwim> robehend1: no, force into fluxbox
| |
| 09:26 | <robehend1> knipwim: for configs, did you just like put the fluxbox config files in /etc/skele, so all users get the same? or I guess Flux could work differently, not familiar with it.
| |
| 09:26 | <Appiah> if you just install icewm via packagemanger I think people will have the option to switch to IceWM (just like GDM does)
| |
| 09:26 | and you can set the default
| |
| 09:26 | <robehend1> Appiah: ldm has that option?
| |
| 09:26 | litlebuda has joined #ltsp | |
| 09:26 | <knipwim> robehend1: that could be done
| |
| 09:26 | <Appiah> I think so, not 100% sure
| |
| 09:27 | <knipwim> robehend1: although all users have their own config now
| |
| 09:27 | robehend1: and, the LDM_SESSION doesn't work since ldm-2.2, but that might be a gentoo issue
| |
| 09:27 | <robehend1> knipwim: ah, true. anyway that I could like, setup a default config, put it somewhere, and have all users use that? I'm trying to find a replacement for Sabayon, so I can control what kids can and cant get too, etc
| |
| 09:27 | <Appiah> https://bugs.launchpad.net/ubuntu/+source/ldm/+bug/67397 LDM does seam to have the option

| |
| 09:30 | oops, sorry
| |
| 09:31 | robehend1 has left #ltsp | |
| 09:31 | <knipwim> robehend1: i think that should be possible somehow, either a central default config, or symlinking each user config from a default one
| |
| 09:31 | too late :(
| |
| 09:32 | <Dantix> the ltsp's clients logs are at --chroot--/var/log?

| 10:27 | <alkisg> Dantix: does debian still use hal? What's your actual problem, besides the warning?
| |
| 10:28 | Or, what problem did you have with ubuntu?
| |
| 10:29 | <Dantix> alkisg: seems nothing more that a annoying message every time the client boots
| |
| 10:31 | alkisg: I've tryed to add dbus and hal to all rc..d directories, but the popup still appears
| |
| 10:31 | dlezcano has quit IRC | |
| 10:31 | <alkisg> moment, phone...
| |
| 10:32 | <Dantix> alkisg: with ubuntu the clients never ends to boot.
| |
| 10:35 | <alkisg> Back
| |
| 10:36 | Dantix: maybe some program tries to use hal and it's not available
| |
| 10:36 | I don't think you need to add hal just for a warning...
| |
| 10:36 | With Ubuntu, if you had some specific error message we could help, but since you moved to debian np
| |
| 10:37 | To add a service the usual command is update-rc.d
| |
| 10:37 | (in debian/ubuntu)
| |
| 10:38 | But if you just reinstall a service it should be automatically enabled (as ltsp-build-client disables a lot of them)
| |
| 10:39 | <Dantix> alkisg: I think I'll try to come back to Ubuntu and start from zero.
| |
| 10:39 | <alkisg> No problem either way, both are nice environments
| |
| 10:39 | robehend1 has joined #ltsp | |
| 10:39 | <alkisg> And most glitches (like not booting at all :D) can usually be worked around easily
| |
| 10:40 | <Dantix> thanks for you support, Ill back with news when I'll be on my new installation
| |
| 10:42 | <robehend1> i forget: if i change something in lts.conf, say directx = yes , do I have to rebuild the image or just restart the clients
| |
| 10:42 | <alkisg> Nope
| |
| 10:43 | <robehend1> ah, nice. I'm going to see how much of a savings I get with no encryptoin
| |
| 10:43 | <alkisg> Muuuuuuuuch better speed ;)
| |
| 10:45 | <robehend1> another random. if i do the disable_compiz thing, do I have to do it per client, or just once on the server?
| |
| 10:45 | !disable_compiz
| |
| 10:45 | <ltspbot> robehend1: "disable_compiz" :: To disable compiz, try: sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/session/required_components/windowmanager metacity
| |
| 10:45 | <robehend1> bah

| 13:37 | <cemc> hi. I would like to disable remote logging on the thin clients, that they don't send logs to the server. I understand that that's on by default, even if the server isn't set to receive them?
| |
| 13:38 | <alkisg> Yup
| |
| 13:38 | You need to define the logging server in lts.conf to enable it
| |
| 13:38 | !lts.conf
| |
| 13:38 | <ltspbot> alkisg: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
| |
| 13:39 | <cemc> I would like to _disable_ it actually
| |
| 13:39 | <alkisg> It is disabled
| |
| 13:39 | by default...
| |
| 13:39 | afaik...
| |
| 13:39 | * alkisg double checks | |
| 13:40 | evil_root is now known as zz_evil_root | |
| 13:40 | <alkisg> Hmm...
| |
| 13:40 | <cemc> if you don't set the specific SYSLOG_SERVER, then SERVER is used. but I don't want it to use anything.
| |
| 13:41 | if I ssh to the thin client, I see /etc/rsyslog.d/lts.conf, and there it's *.* <servers_ip>
| |
| 13:41 | redbaritone has joined #ltsp | |
| 13:43 | <alkisg> And if the server is not configured to accept connections, it falls back to logging locally on the thin client?
| |
| 13:43 | Because there are log files locally (I have not configured my server to accept connections)
| |
| 13:44 | <cemc> not sure, I didn't check that yet. I thought syslog gets sent through UDP, so even if the server doesn't receive it, it's still being sent (again, I didn't check that yet)
| |
| 13:44 | I just thought I ask here first, if there's even an option to not do remote logging, to not even set it up on the thin client
| |
| 13:47 | <alkisg> I don't see such an option in the code
| |
| 13:47 | Ah
| |
| 13:48 | Try SYSLOG=anything else than empty "" or "remote"
| |
| 13:48 | E.g. SYSLOG=local
| |
| 13:49 | I see in the code that this should work, but I don't find any references for that variable anywhere at all..
| |
| 13:50 | (in lts.conf)
| |
| 13:52 | <cemc> me neither, that's why I was confused
| |
| 13:53 | <alkisg> Btw the relevant code is in /opt/ltsp/i386/usr/share/ltsp/ltsp-init-common
| |
| 13:53 | <cemc> alkisg: it seems to work
| |
| 13:53 | there's no ltsp.conf file generated in /etc/rsyslog.d/
| |
| 13:53 | so that's good then
| |
| 13:53 | <alkisg> Right, but I wonder why that's completely undocumented...
| |
| 13:54 | <cemc> maybe it was a quick hack and it got forgotten ;)
| |
| 13:54 | <alkisg> Probably :)
| |
| 13:55 | <cemc> is there a bugreport page somewhere?
| |
| 13:56 | [GuS] has quit IRC | |
| 13:56 | <alkisg> Not sure if that code is in all distros, which one are you using?

| |
| 13:59 | dr_data has joined #ltsp | |
| 14:00 | <cemc> btw, the logs do get sent even if the server is not configured to receive them, I checked. they're sent to port 514/udp
| |
| 14:00 | without SYSLOG=local
| |
| 14:04 | alkisg: what about this: https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/197744 ?

| 14:26 | <vagrantc> hrm. with the new version of debian, non-free firmware split out of the kernel... feel like would have to include the non-free parts of the repositories and the non-free firmware in order to have people not revolt
| |
| 14:26 | :(

| 14:29 | <italovalcy> hi guys! I'm using ltsp-cluster here and it's working very good! My doubt is: is there an way to don't display the information screen at end of ltsp-client's boot?
| |
| 14:29 | <Q-FUNK> vagrantc: typical debian.

| 14:30 | <italovalcy> I'm talking about this screen: http://www.arkki.info/howto/Wiki/LTSP-Cluster/LTSP-ClusterControlCenter-05.png
| |
| 14:34 | <vagrantc> Q-FUNK: to be clear, i'm supportive of the decision to make it clear when people are using non-free components, otherwise it's hiding problems that people will actually have.
| |
| 14:35 | i think it's the right decision, it just has some consequences

| 14:43 | <italovalcy> hey, I've found that such screen is called by ltsp-cluster-info from /opt/ltsp/i386/usr/share/ltsp/xinitrc.d/I00-cluster
| |
| 14:43 | to call that script, we have a condition based on variable CLUSTER_CONFIGURED
| |
| 14:44 | if ! boolean_is_true "$CLUSTER_CONFIGURED" && [ -n "$(which ltsp-cluster-info)" ];
| |
| 14:44 | johnny has joined #ltsp | |
| 14:44 | <italovalcy> what the usage of that variable?
| |
| 14:44 | I mean, can I just set it to TRUE?
| |
| 14:46 | <Gadi> italovalcy: I believe that it gets set once a workstation is added to a node other than the root node in the control center
| |
| 14:46 | <italovalcy> or, IMO, this could be configurable through another variable... something like: DISPLAY_CLUSTER_INFO=True/False, what do you thinnk?
| |
| 14:49 | Gadi: I didn't understand... somethink like a static node (appserv) through the web interface?
| |
| 14:50 | <Gadi> italovalcy: in the web interface, create a node
| |
| 14:51 | then, move the workstation under that node

| 15:05 | * alkisg wonders if aufs[nbd rofs, + nbd cow] + nbd swap would be better than aufs[nbd rofs, tmpfs] + nbd swap, especially for fat clients... or caching makes those somewhat equivalent? | |

| 16:12 | <alkisg> Yet another crazy idea... :P when btrfs is stable, to switch from squashfs to a sparse file-based "partition" with a compressed btrfs file system in it, served with nbd-server -c.
| |
| 16:12 | That will completely avoid the need for tmpfs/aufs on the client, will reintroduce compression for less bandwidth, and will allow rsync to be used for ltsp-update-image, resulting in fast updates of big fat client images...

| 16:35 | <vagrantc> alkisg: who needs rsync ... you could just mount the image to update it, no?
| |
| 16:37 | <alkisg> vagrantc: sure, but the clients would need to be offline for that
| |
| 16:37 | So that extra "update-image" step is handy there...
| |
| 16:38 | * vagrantc has updated ext2 images live without anything crashing | |
| 16:38 | <vagrantc> not that i used it extensively ... and it kind of perplexed me that it continued to work ...
| |
| 16:38 | probably a little different with the nbd cow support, too
| |
| 16:39 | i.e. when you've mounted something read-only you don't need to worry about update clashes
| |
| 16:39 | although i'd think caching woudl get in the way
| |
| 16:40 | <alkisg> I too had by mistake done that, i.e. I had the .vdi disk open with vbox, and at the same time mounted with vdfuse and exported with nbd-server -c, and it all worked, but I don't know if that was just luck
| |
| 16:42 | (and a fat client booted from the nbd cow image)
| |
| 16:46 | Ah. Logic failure. If I mount the image rw to rsync/update it, I might as well update it online.
| |
| 16:46 | Snapshots would be handy there :D
| |
| 16:47 | <vagrantc> yeah

| 17:52 | <tekoholic> Which file do I send another dhcp config utility to, as the boot image in LTSP?
| |
| 17:53 | <alkisg> You mean that you have an external dhcp server?
| |
| 17:54 | <tekoholic> No, I mean that I use (on same server) Zentyal, for network and DHCP config, and it asks for a boot image. Which file do I direct it to?
| |
| 17:55 | <alkisg> Do you use tftpd-hpa for tftp?
| |
| 17:55 | Or does it have another tftp server?
| |
| 17:55 | The boot filename in ubuntu/debian is /ltsp/i386/pxelinux.0, relative to the tftp root dir
| |
| 17:56 | I don't know about other distros...
| |
| 17:56 | <tekoholic> I believe that it uses tftpd-hpa, verifying now. This is an Ubuntu-LTS based system. You can check it out @ zentyal.org
| |
| 17:57 | alkisg, It does use tftpd-hpa
| |
| 17:57 | 5.0-11ubuntu2.1, to be sure
