hey people happy new year
I'm in Madagascar and I don't have enough bandwidth, I would like to use my ltsp-server to update my ltsp-image
I'm on LUbuntu Maverick
when I do an update with aptitude on the server, it downloads everything that will be downloaded again when I chroot in the ltsp
so packets are downloaded twice
antilyman, install apt-cacher and set it as proxy for both.
But you still need use same arch for both, otherwise no help from that.
they're on the same arch
I was like installing apt-mirror
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.
ok I catch it
And apt-cacher doesn't use your network by own like apt-mirror does.

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

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.
is this the client?
What dist are you running?
yes the client, Debian Lenny
|09:16||robehend1 has joined #ltsp|
has anyone used IceWM as a desktop enviro for LTSP?
Dantix: weird , thought debian would add things like that automaticly
robehend1: read about people using other things then GNOME and KDE
using WM's instead of DE's
hmm, guess ill have to play with it.
search the mailinglist
Appiah: yes, weird, I've just add the link en every rc folder and testing
|09:21||alexqwesa has quit IRC|

robehend1: found one here saying they switched to IceWM and things went quicker
i'm hoping for quicker, as well as less overhead, as well as throwing a easy to use theme on there for my kindergarten
it's just a matter of making it start IceWM instead of gnome..
yep. thats through init scripts, correct?
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||vvinet has quit IRC|
|09:24||cyberorg has joined #ltsp|
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|
robehend1: no, force into fluxbox
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.
if you just install icewm via packagemanger I think people will have the option to switch to IceWM (just like GDM does)
and you can set the default
Appiah: ldm has that option?
|09:26||litlebuda has joined #ltsp|
robehend1: that could be done
I think so, not 100% sure
robehend1: although all users have their own config now
robehend1: and, the LDM_SESSION doesn't work since ldm-2.2, but that might be a gentoo issue
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
https://bugs.launchpad.net/ubuntu/+source/ldm/+bug/67397 LDM does seam to have the option

Dantix: does debian still use hal? What's your actual problem, besides the warning?
Or, what problem did you have with ubuntu?
alkisg: seems nothing more that a annoying message every time the client boots
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|
alkisg: with ubuntu the clients never ends to boot.
Dantix: maybe some program tries to use hal and it's not available
I don't think you need to add hal just for a warning...
With Ubuntu, if you had some specific error message we could help, but since you moved to debian np
To add a service the usual command is update-rc.d
But if you just reinstall a service it should be automatically enabled (as ltsp-build-client disables a lot of them)
alkisg: I think I'll try to come back to Ubuntu and start from zero.
No problem either way, both are nice environments
|10:39||robehend1 has joined #ltsp|
And most glitches (like not booting at all :D) can usually be worked around easily
thanks for you support, Ill back with news when I'll be on my new installation
i forget: if i change something in lts.conf, say directx = yes , do I have to rebuild the image or just restart the clients
ah, nice. I'm going to see how much of a savings I get with no encryptoin
Muuuuuuuuch better speed ;)
another random. if i do the disable_compiz thing, do I have to do it per client, or just once on the server?
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
Just runit onserver. It disables for all clients.

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?
You need to define the logging server in lts.conf to enable it
alkisg: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
I would like to _disable_ it actually
It is disabled
|13:39||* alkisg double checks|
|13:40||evil_root is now known as zz_evil_root|
if you don't set the specific SYSLOG_SERVER, then SERVER is used. but I don't want it to use anything.
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|
And if the server is not configured to accept connections, it falls back to logging locally on the thin client?
Because there are log files locally (I have not configured my server to accept connections)
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)
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
I don't see such an option in the code
Try SYSLOG=anything else than empty "" or "remote"
I see in the code that this should work, but I don't find any references for that variable anywhere at all..
me neither, that's why I was confused
Btw the relevant code is in /opt/ltsp/i386/usr/share/ltsp/ltsp-init-common
alkisg: it seems to work
there's no ltsp.conf file generated in /etc/rsyslog.d/
so that's good then
Right, but I wonder why that's completely undocumented...
maybe it was a quick hack and it got forgotten ;)
is there a bugreport page somewhere?

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?

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

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.
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...

alkisg: who needs rsync ... you could just mount the image to update it, no?
vagrantc: sure, but the clients would need to be offline for that
So that extra "update-image" step is handy there...
|16:38||* vagrantc has updated ext2 images live without anything crashing|
not that i used it extensively ... and it kind of perplexed me that it continued to work ...
probably a little different with the nbd cow support, too
i.e. when you've mounted something read-only you don't need to worry about update clashes
although i'd think caching woudl get in the way
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
(and a fat client booted from the nbd cow image)
Ah. Logic failure. If I mount the image rw to rsync/update it, I might as well update it online.
Snapshots would be handy there :D

Which file do I send another dhcp config utility to, as the boot image in LTSP?
You mean that you have an external dhcp server?
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?
Do you use tftpd-hpa for tftp?
Or does it have another tftp server?
The boot filename in ubuntu/debian is /ltsp/i386/pxelinux.0, relative to the tftp root dir
I don't know about other distros...
I believe that it uses tftpd-hpa, verifying now. This is an Ubuntu-LTS based system. You can check it out @ zentyal.org
alkisg, It does use tftpd-hpa
5.0-11ubuntu2.1, to be sure
