mm is it in general possible to start two ldm sessions on one client? At the moment i have one xfreerdp session on SCREEN_02 and one ldm session on SCREEN_07, when i add SCREEN_03=ldm to the lts.conf just the ldm session on SCREEN_07 starts . SCREEN_02 and 03 are empty did not found any usefull error messages jet. anyone have experience with two ldm session on one client? i would love to be able to switch between Users without logout/login every
Firstly comes to my mind that LDM was not desinged to be running twice on same machine so it might use some hardcoded filenames and session starting to screen 7 overwrites session started to screen 3.
a good morning every one bye the way :D
It's just my 2 cents.
It's noon already. ;)
muppis: that would not explain why the xfreerdp session also is not starting. I have more the felling that I'm running in some kind of fallback default setting but unfortunately there is no central place for the default conf for the different settings they all hide some where in the bash scripts. My body Clock says it is morning and thats override the System time by default in my Mind.conf
|09:50||adrianorg__ has joined IRC (email@example.com)|
There can be a change that parsing of lts.conf fails due double definition of ldm sessions.

muppis: ok its definitely possible to run 2 ldm sessions (i did it by making chmod 777 /var/run/ldm-xauth-blabla/Xauthority and mounting the home dir Manuel and then calling then xinit /usr/share/ltsp/xinitrc) I guess this Xauthority think could be passed by by creating a new one. So there is no design error in the LDM as you mentioned first time. I will stop digging in this direction because I dont want invest to much time into this but would
be still interested if somebody has a 2 LDM session setup running and how he did it because my dirty hacks are obviously not a good solution

sbalneav, knipwim, jammcq, Enslaver, Hyperbyte, stgraber, highvoltage: Here's the proposed new syntax for the configuration files, if you agree we could have it ready before the hackathon:
I haven't yet written the pros, will do so in a while
I would sure like to see stuff indented under the section headers
jammcq: that's against the configparser syntax
I think it's defined in some RFC
It's to allow continuation of multiple lines
E.g. VAR=Line 1
Otherwise we'd need quoting, and so then it would need escaping for inserting actual quotes,
and it would get messy when one wants to enter e.g. a sed line in an RCFILE_0 option
"The configuration file consists of sections, led by a [section] header and followed by name: value entries, with continuations in the style of RFC 822 (see section 3.1.1, “LONG HEADER FIELDS”)"
alkisg: looks very much like the old one. it's nice that you wouldn't need a default section anymroe
highvoltage: yup, the idea is to allow for some conditionals, e.g. [RAM > 500], without disturbing sysadmins too much with a complete new syntax...
The major changes are conditionals, no indentation allowed except for continued lines, no quoting, and [mac] now gets written as [mac = value]
alkisg: ehm, I would propose default / suggested name for ltsp server not being "server" but "ltspserver" or something more unique ;P
markit: that's not related to the configuration changes though :)
Let's not mix subjects
alkisg: the friend of mine that is installing ltsp in 4 schools, has some problems with a "monster" server (2 cpu, 64 gb ram, 4 nic). Was not able to make it work with 32 bit ubuntu, was very unstable. 64 bit seems to work fine. Now has some "random" problems with clients, sometime someone has no panel or is missing some icons... did it happen to you sometime? Client hw is not very good, nor he is sure about cabling
alkisg: ups, did not realize you were discussing that topic, sorry
I queue up
alkisg: no, gnome fallback
but is not urgent, define your config stuff first ;P
alkisg: oh, we use greep repo, so is just a matter of wait and update? great
The update will come as part of "sch-scripts"
Not from "gnome-panel"
I see... I'll point him to that bug imediately, thanks a lot
|17:29||meamy has left IRC (firstname.lastname@example.org, Quit: meamy)|
funny, he deployed already 2 schools, but had this issue only now on the last one
that was the more "unstable"
(64 bit, biprocessor, cabling uncrtain in quality, etc..)
markit: what kind of problems were there with 32bit installation? Did it freeze or something like that?
vmlintu: he told me that unity was very sluggish, mouse movements and so on
markit: ok.. never tried running unity on server hardware, so cannot say much..
well, never really run X on server hardware..
alkisg: are there parsers for other languages?
configparser parses ini-style configuration files
|17:53||adrianorg__ has left IRC (email@example.com, Read error: Operation timed out)|
shlex helps a bit in parsing shell syntax
compile() can parse a python file...
Is that what you're asking?
You could easily extend the ltspd daemon with a python module...
If I'd need to parse those config files on ruby, is there something available?
Ah. I guess so, .ini files are one of the most common formats
I really don't know much on .ini file and what parsers support..
Can one use real arrays in them?
Personally I do not like the XXX_0, XXX_1 style
vmlintu: all those values are supposed to be exported on the client environment so that bash scripts can act on them
Errr actually shell scripts, not bash scripts
Those don't support arrays
That's why we also don't want the server side to support arrays...
But it'll be easy now to have multiline values
So e.g. instead of FSTAB_0 to 9, one could have FSTAB=Line 1
line 2 etc etc
But that only makes sense in some cases... e.g. on XRANDR and on RCFILE as well
But not on all of them
The downside is that you cannot add one line from a later configuration file without overriding the older value
yes, multiline makes things nicer

alkisg: about puavo-tftpd - it's been now in use without problems this week.. We'll do some cpu optimisations for it, though, as some ruby functions turned out to be quite slow..
vmlintu: he was installing ltsp and setting it up. In any case, in "my" schools we use the server as workstation for the teacher, and indeed has some risk
vmlintu: hmmm I want to get the opportunity to introduce a new configuration system now with ltsp6, but I don't feel confident enough to propose puavo-tftpd because it hasn't been extensively used yet and I haven't even see it ... :-/
|18:07||Phantomas has left IRC (Phantomas!~Phantomas@ubuntu/member/phantomas, Ping timeout: 272 seconds)|
An "ltsp-config apply" command will be able to generate pxelinux.cfg/01-mac files from the /etc/ltsp/config.d/* files, if that helps
So we'll also be able to do [MAC = xxx] KERNEL_PARAMS=yyy
And if someone cares, we can also put DHCP options support there as well
All those, plus a GUI editor, should be good enough for both simple and advanced users... I hope
But if puavo-tftpd proves to be stable enough, I'd suggest that you submit it at least to debian/ubuntu, so that people can install that as a tftp server and get advantage of the new possibilities it offers
If you could also put proxydhcp support in it (it should be very simple, in java it's just a few lines), then people wouldn't even need a dhcp server either
|18:12||* markit googling for puavo-tftpd but github page tells nothing about features and also what it is (I guess a tftp server from it's name)|
markit: search the irclogs for it
yes, it's still really early in life cycle.. we are not really pushing it yet for outside use yet before we have it running on more servers..
thanks but really developers should put some lines about the generic features of their projects!
vmlintu: oh, you one of the devs, read my comments then ;P
btw, why ruby? I use it for ruby on rails devs, and I've done some scripts that help me install and configure ltsp, but most people use Python
markit: yes.. I've been working on docs on and off..
I feel less alone now ;P
our management tools are all written in ruby
Other stuff mostly on nodejs
I've to leave now, thanks a lot bye

My client boot failure is due to NFS refusing connectio to an "unmatched host". I don't know what that means. Using 'range' in dhcpd.conf and thought that would avoid this. Do I need a host file entry or something with the client's MAC address?

|21:08||* gvy runs current ALTSP on 32M RAM, a clear regression from 16M five years ago :-/|
what version of LTSP?
took some time for a forward port but didn't quite make through (and there were things going to change so postponed it for a week or two, that is came back in a year)
the regression is due to generic kernel :)
it seems kind of implausible and still running current software ... X alone on my machine is taking 10-30MB of ram, depending on how you count it
what corners are cut?
X: ~8M i586, ~16M x86_64
mine was on i686
built for i486
X seems to take varied amounts of memory depending on the total available
also depending on what's actually running
messing with today's images, yesterday's snapshot is available here just in case: ftp://ftp.linux.kiev.ua/pub/Linux/ALT/people/mike/iso/terminal/
i.e. how many clients are displayed
it's for a kdm
gvy: do you have any commits for upstream ltsp?
vagrantc, I have to catch up as usual :-)
the changes I've seen during that attempt were okay
and I'm all for upstream merge as always
11M X RSS (i586) given TDE session + firefox

|22:34||* vagrantc bows thankfully|
alkisg: do you have a way to reliably reproduce the "programs continue to run after logout" problem?
vagrantc: it depends on the apps that are running, but no I haven't pinpoint which of them reproduce the problem,
alkisg: i'm trying to verify it with the unpatched verson, but everything works as expected :)
i.e. I've seen installations where it doesn't happen, and installations where it always happens,
but, here's another part that you can always verify:
alkisg: i've tried with icewm + iceweasel, lxde + iceweasel + leafpad + random otehr stuff, xfce ... they all work as expected
On first login that works
On second login, it says something about pipe disconnected
While with the patch it does work
That's always reproducible, even on installations where the sshfs problem doesn't appear
lxde doesn't apparently mount ~/.gvfs at all
Btw, some reading for afterwards: http://wiki.ltsp.org/wiki/Dev:Ltspd
A proposal for a new configuration system - although I haven't yet written the pros and cons
alkisg: i'm having zero luck reproducing this problem ...
I've seen it with gnome and kde
I haven't tried lxde/xfce...
|22:41||* vagrantc was going to try gnome next|
$ grep gvfs /proc/mounts
gvfs-fuse-daemon /home/alkisg/.gvfs fuse.gvfs-fuse-daemon rw,nosuid,nodev,relatime,user_id=1010,group_id=1010 0 0
also, session saving seems broken again :(
In .dmrc? Meh
it's not writing out a .dmrc at all
|22:46||work_alkisg has joined IRC (email@example.com)|
i should probably reinstall from scratch, just to make sure i haven't manually tweaked soemthing somewhere.
|22:50||* vagrantc wonders if fatclients try to write out ~/.dmrc before or after sshfs is mounted|
They write that to the server, don't they?
Not in the sshfs mount... but via the socket
thought so ...
|22:58||work_alkisg has left IRC (firstname.lastname@example.org, Ping timeout: 240 seconds)|
alkisg: so, i don't see a .gvfs even in gnome...
|23:00||bobby_C has left IRC (bobby_Cemail@example.com, Ping timeout: 276 seconds)|
alkisg: have you seen this on Debian?
vagrantc: do you have gvfs-fuse installed?
No I haven't seen it on debian - I have a debian chroot for testing but it's a thin one
|23:06||* vagrantc tests again|
The gnome session is started with dbus-launch in front of it, right?
the attempt without gvfs installed was on a thin client
and now trying with a fatclient crashes without gnome-fallback kicking in
alkisg: with gvfs-fuse installed, it still doesn't create ~/.gvfs ...
|23:17||* vagrantc wonders if ~/.gvfs got replaced by something newer and shinier|
And ubuntu still ships it? I wouldn't be surprised at all...
But the problem is not limited to .gvfs, it was just easier to reproduce that one
|23:18||* vagrantc can't reproduce the problem at all...|
I can get a list of applications that produce the problem next week
|23:19||* vagrantc can't in good confidence upload such an intrusive fix without the ability to reproduce the problem|
But i do know it's very common in ubuntu, many teachers reported that (and most wouldn't understand/report it even if it happened)
vagrantc: feel free to either close it or lower its significance, I was just trying to help with filing it there
