Happy new year to all
Thank you and same to you.
alkisg, got boring evening so I played little with ltsp. Had rebuild whole image to get autologin to work.
Rebuilding should be necessary though...
But now need to disable Gnome screensaver as xbmc has build-in one and it works better when not using keyboard nor mouse.

Gnome screensaver has "blank only" hardcoded for ltsp clients afaik
Cannot be disabled?
Well, hope it doesn't cause massive problems.

Urm vbox just crashed my kernel when I tried to change host-only networking settings...
Maybe it got little hangover from last night?
But I think I gotta go out with the kids. There plenty of snow there..

nbd-server -c seems very stable, the diff is 1.2 Gb so far and it's still fast (I even used it to make a /swap file on the client...)
that's the cow option?
I netbooted a natty vm off of it by just installing nbd-client and setting eth0 inet manual in interfaces, and now I'm stressing it...
Also nfs+tmpfs with aufs was stable
Next I want to test nfs + cow nbd instead of tmpfs + aufs
wow. last time i tried nfs with aufs it exploded badly
It needs mount --move, it doesn't like mount --bind
do we do mount --bind anywhere?
(and I tested with the same paths, /rofs and /cow, I don't know if it matters)
I think so, yes
I.e. if ot
mount --move is so much better if it works
I.e. if it's mounted on /cow and then made available on another path, maybe it has problems then
It makes mtab work ok (it's writeable then)
No need to symlink it to /proc/mounts
While mount --bind makes duplicate entries in mtab
one of the problems with mtab is not writing to mtab itself, but that files assumed they could write to /etc/mtab?*
i think there are a few other files with similar issues ...
With nfs + [tmpfs | empty cow nbd] + aufs, it's not a problem, they can write wherever they want...
passwd and group and such
that would be slick
After implementing it, I saw a web page that described exactly how I did it... http://www.logicsupply.com/blog/2009/01/27/how-to-build-a-read-only-linux-system/
Nope, after 40 minutes of stressing (the diff went to 1.3G) no noticable delay in nbd-server -c.
No failures in syslog, all seem fine
very, very cool.
alkisg: did you just tweak the ltsp_nbd script to support it?
No, I'm testing without LTSP
Just a VM installation of natty, exporting the .vdi disk with nbd
the .vdi disk is readable as a normal disk?
And I only installed nbd-client in the VM + added eth0 inet manual in interfaces so that network-manager doesn't touch it
vdfuse from virtualbox-ose-fuse can export the partitions as block devices
So they can be loop mounted or exported with nbd-server
Ah, so there was also the vdfuse overhead, heh, I didn't notice it
I bet with squashfs and without vdfuse it'll go even faster
(it's usually 2.5 times faster, measured on my fat client labs... cool)

|13:12||* alkisg goes on to write an ltsp-update-image equivalent for vbox VMs...|
Heh, tmpfs/aufs is also handy there, it allows for chroot-installing nbd-client + tweaking interfaces/fstab without having to modify the VM beforehand
(either that or mounting the VM partition with nbd-server -c, which makes it cow)

what do you guys think of x2go and do you think it is a worthy replacement for LTSP as far as terminal server/clients go?
i hope no one takes offsense to the question, i just started to use it as a replacement for NX (NX started giving me some fit)
and now i am wondering if it would be better to replace ltsp with it instead.
there's nothing wrong with ltsp in my mind, and in fact i love it. i'm just questioning my setup.
i think x2go would give me the ability for 'session' management; and i like that. i want to be able to boot up a machine at work, suspend that session, go home and then connect to the same sesion from home.
if you have any thoughts i would be interested in hearing them.
I've never used it, but if it uses nx, then it's not very fast for video etc
X is the fastest there is for local network
(when direct, without ssh)
Unfortunately I don't know of any good x-proxy implementations that could combine both speed + session management...
With a good x-proxy, plain X could still be used locally for speed, and then something nx-based from home (adsl etc), with session pause/resume in both cases...
Also maybe nx-based solutions won't scale well for too many clients, I imagine they raise the server CPU too much

thank you for your explanation alkisg.
what is this ltsp-clustering used for?
