But I think you need to add some package in the chroot that slows the cpu down, something about power management but I don't remember it
|02:23||sbalneav has joined #ltsp|
alkisg: any documentation somewhere?
It's not LTSP specific, so probably in the ubuntu wiki or something
I didn't know that client-side is also possible to install something
sudo chroot /opt/ltsp/i386 apt-get install package && sudo ltsp-update-image
|02:30||IOU has quit IRC|
hahlo: on the localxterm, try: cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
What do you get?
hahlo: you need to change that to "ondemand"
Search for the package that does this. If you don't find it you can put a script that does it, but it's better to find the package.
can laptop-mode do that?
Hmmm... /etc/init.d/ondemand, package "initscripts"
That should already be in the chroot...
CPUFreq Utilities: Setting ondemand CPUFreq governor... disabled, governor not available...
Check if it still does that with an ubuntu live cd
hahlo, do you cpufreq-selector from gnome-applets ?
but suddenly fan eased up don't know why didn't notice any diffrence in local xterm
I use that from cli and as an applet in my laptop, but I don't use this as LTSP client.
What is your load history?
hahlo: if the fan eased up, try: cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor again to see if the governor changed by some script
alkisg: yes now ondemand
I think the ondemand script scales it down after 60 seconds (to have a fast boot), maybe for some reason it takes longer for your ltsp client...
So anyway if it does that after a few minutes, np then...
ok cool I can live with that
btw my ltsp-server is desktop machine with nvidia videocard, now using nouveau, any improvment to install nvidia-driver?
|03:34||bobby_C has joined #ltsp|
hahlo: you'll see improvement only on the server, although there's a small possibility that it might cause problems on some clients
I got NV8500 GT in my headless server.. What overdoze..
But what rattrap it is. Server is in attic and I placed trap just in airflow. No rat problem anymore.

so backup my image, i just copy /opt/ltsp/i386 correct?
Correct (while preserving file attributes)
okay, thank you (cp -p)
what about 3d in ltsp noticed that client says direct rendering yes but glxgears runs slow, does it depend client hardware or what?
this command should take care of my backup correct?: sudo cp -Rp ltsp ltsp_backup
thank you muppis :)
Alternative command what I use is rsync -av ltsp ltsp_backup
aah which is best?
hahlo: 3d runs slow over the network
i guess rsync only copies diffs right?
AndyGraybeal: Right, so it's better if you want to re-sync later on
|08:00||* alkisg just copies the images/i386.img file, much quicker :D|
alkisg: nice :)
do you guys run a cron job for that?
Cron job? Why? If you want it automated, just put it at the end of ltsp-update-image or whatever else you use when you modify the chroot...
AndyGraybeal, just keeping in mind installed packages. Everything else is quickly rebuild.
alkisg: ah come on! why not copy over the same file every day? you're boring
|08:03||bobby_C has joined #ltsp|
|08:04||* alkisg humbly apologizes, I didn't think of that parameter... :D|
alkisg: okay, thank you
muppis: thank you too.
AndyGraybeal: btw, I use this method when I want to do things at the same time I run other commands:
create a ~/bin/ltsp-update-image
/usr/sbin/ltsp-update-image && backup chroot
This way when I run ltsp-update-image the backup also runs, and I don't need to worry about ltsp upgrades / dist-upgrades etc
(~/bin gets first in the PATH if it exists when the user logs in)
|08:08||Gadi has joined #ltsp|
is backup a program or a script?
&& backup chroot
Whatever you want, I don't do backups, I just gave an example...
ah yes, yes, thank you
You could put this in its place: ltsp-update-image "$@" && rsync -av /opt/ltsp/i386 /opt/ltsp-backup/
real men don't do backups
yes, i understand, i'm sorry i just needed a little clarification
|08:12||* alkisg does a lot of backups for /home though :D|
"$@" <-- i'm not familiar with this
i run backups every night :)
eventually i want to run zfs and do snapshots :)
well.. LVM snaps too.. but i'm not there yet.
That means "pass to /usr/sbin/ltsp-update-image all parameters that were passed to ~/bin/ltsp-update-image", like e.g. --arch fat-i386

good morning everyone
Good morning mgariepy
alkisg: zfs seems awesome, i haven't been able to wrap my head around the zones, containers, datasets, and all that..
i think i'm going to need to cozy up with a book one weekend for it
but i really like the ACL's.

mgariepy: did you spread the news about remoteapps?
What news about remote apps?
Kyle__: one of the things mgariepy and I hacked up over the weekend at BTS was a working remoteapps implementation
so you could run local firefox and have openoffice links open the doc on the server
should also make it easy for folks running fat clients to choose to have some apps open remotely, too (should that be desired)
|10:02||* alkisg thinks that would be handy for gnome-about-me on fat clients ;)|
(i.e. to enable the users to change their passwords and other info)
alkisg: "xauthority" :: to access the client X session from a local root shell, try: eval $(tr '\0' '\n' < /proc/$(pidof -s ldm gdm-simple-greeter gnome-session | cut -d' ' -f1)/environ | egrep '^DISPLAY=|^XAUTHORITY=') && export DISPLAY XAUTHORITY

I've problems booting old pc that has not PXE lan boot. I'm using eb-5.4.4-rtl8139.zlilo but It doesn't find dhcp server
the same with gpxe
Uzzi: do you get the DHCP.....\
alkisg: "gpxe" :: the successor to etherboot (http://etherboot.org). To download bootable floppy, cd, usb, kernel etc images, visit http://rom-o-matic.net/
Uzzi: use gpxe instead of the older etherboot versions
Booting from etherboot (.nbi images) is broken in recent Ubuntu versions, and maybe in other distros too
I didn't read all the lines :D
alkisg, with gpxe and debian server it doesn't find dhcp server! a laptop on the same network cable works fine
Which gpxe version?
Gadi: nice, pam-sshauth will be much appreciated!
Uzzi: can you try with specifically 1.0?
0.9.5 is too old...
(and I've been experiencing problems with 1.0.1 ...)
|11:29||jroberts235 has joined #ltsp|
alkisg, http://rom-o-matic.net/gpxe/gpxe-1.0.0/contrib/rom-o-matic/ this?
ok I try with this gpxe-1.0.0-gpxe.dsk

Uzzi: press ctrl+B to get a command line in gpxe,
then run: dhcp net0
|11:41||RiXtEr has quit IRC|
And see the dhcp info it receives, and check if it is correct or not
root-path it's ok
...so I got Fedora 13 working with LTSP, but I seem to be having a really big problem with X. The taskbar does not populate with open windows, and there is no border around open windows.
Uzzi: boot filename? next-server?
/opt/i386 ecc ecc
Uzzi: then you need to fix your dhcp server?
Put next-server in dhcpd.conf
Also, is really boot filename supposed to be /opt/ltsp/i386.. etc? Are you exporting the whole / with tftp?
Check /usr/share/doc/ltsp-server/examples/dhcpd.conf for a sample dhcpd.conf, I think it exists in Debian too (using Ubuntu here)
alkisg, Thanks now works fine!!!!!
