00:16
<piet>
I have tried to define <LOCAL_APPS_EXTRAMOUNTS=/xxx,/yyy,/zzz> this way to get server dirs mounted on fat-clients, but they dont show up. Im quiet sure they are supposed to be comma seperated so there must be something else wrong with this . . .
00:16
<vagrantc>
(and people also come an go here all the time busy doing other things)
00:17
<piet>
shure, angry about me?
00:18
sorry for this :)
00:18
<vagrantc>
no, just responding to "all over sudden everybody just disappears? May I torch You with another Question?"
00:18
people come and go all day, and respond as they can

<piet>
hey I was just dissapointed by the break. Pls be patient I dont want to do You any harm . . .
00:20
<vagrantc>
and please be patient :)
00:21
<piet>
yes, thats very difficult, because Im very agitated . . .
00:21
just like a little boy who just found a new fantastic toy and doesnt want to stop playing with it, ok?
00:22
<vagrantc>
stgraber: i'll try and get ltspfs 1.0 by sunday or monday, maybe? is that soon enough for ubuntu to pull?
00:22
piet: well, keep playing. that's how a lot of us learned what we know and share
00:23
<stgraber>
vagrantc: sure, we no longer import automatically at this point but just poke me on IRC and I'll sync it from Debian
00:24
<vagrantc>
stgraber: i've also been pondering not using mkdst to ship tarballs with all the autofoo cruft ... and just using dh-autoreconf to handle the autofoo ... cleaner diffs between upstream versions that way.
00:25
<stgraber>
vagrantc: yeah, I know a lot of distros and upstreams are used to putting the full autofoo stuff in the tarballs so they have one "official" source they can use and compare to look for bugs
00:26
vagrantc: but with the LTSP model it doesn't really make sense
00:26
vagrantc: so we might as well stop doing that in our upstream tarballs and let the distros do it (using dh_autoreconf for Debian and Ubuntu)
00:26
<piet>
@vagrantc: yes, yes, yes, yes, yes (and very, very silent - on tip tows - as tiny that You hardly see me ;) what about extramounts?)
00:28
<vagrantc>
piet: i don't know much about extramounts
00:30
<piet>
thats a pitty, sorry when I disturbed You and thank You for Your help!
00:31
<vagrantc>
piet: good luck!
00:37
<piet>
@vagrantc: thank You . . .

<VectorX>
i got a xp vm on a ubuntu ltsp setup, im trying to rdp into that via a thin client, but after the ubuntu init screen i get a black screen
05:22
<alkisg>
Remove SCREEN_07=rdesktop, then login normally to ldm/gnome, then run ltsp-localapps xterm, and then try to rdesktop from that xterm
05:22
Also, which ubuntu version?
05:23
<VectorX>
oneiric
05:23
well i was trying to make the experience seamless
05:23
<alkisg>
There was a bug in the rdesktop script previously, I think it's fixed there, so try what I suggested above
05:23
That will help you troubleshooting
05:23
<VectorX>
ok
05:23
<alkisg>
Once you get that going, then you can revert the SCREEN_07=rdesktop line
05:38
<VectorX>
well that works, so how do i find the problem ?
05:40
only see a warning about the color depth going from 24 to 16
05:41
<alkisg>
VectorX: what are the relevant lines in your lts.conf, and what command did you use from the terminal to connect?
05:43
<VectorX>
[DEFAULT]
05:43
RDP_SERVER = "192.168.0.20"
05:43
rdesktop 192.168.0.20
05:44
<alkisg>
And the SCREEN_ line?
05:45
<VectorX>
_7 = rdesktop
05:45
_07
05:45
<alkisg>
Try removing RDP_SERVER completely, and using SCREEN_07=rdesktop 192.168.0.20
05:45
<VectorX>
k
05:48
that worked
05:48
<alkisg>
The bug I was talking about was probably there in Oneiric too then
05:49
<VectorX>
looks like it

anyone
07:23
so the xp rdp is shwoing up in 800x600 res, how can i make it get the entire screen size

07:47alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg)
07:56
<Hyperbyte>
VectorX, if you change dhcpd.conf you'll have to restart the dhcpd server. Either dhcp3-server or isc-dhcp-server service.
08:03
<VectorX>
ok
08:04
any ideas on the rdp question
08:08
<alkisg>
SCREEN_07=rdesktop -u '' -f 192.168.x.x
08:09
It's the same if you run it on the local xterm you were trying before
08:09
<VectorX>
.x.x ? is that a wild card or fill in the blanks ?
08:10
<alkisg>
Fill the blanks
08:19loather has left IRC (loather!~khudson@wsip-98-175-250-115.sd.sd.cox.net, Quit: This computer has gone to sleep)
08:20
<VectorX>
hmm wiered after adding that, im not getting an rdesktop login
08:20
goes straight to ubuntu
08:21
let me try it from xterm quickly
08:21
<alkisg>
rdesktop -f 192.168.x.x
08:21
it's probably the old code that can't handle ''
08:27
<VectorX>
ok that worked
08:30
<alkisg>
You're welcome
08:31
<VectorX>
;)
10:00
things are looking good, although atm one other thing, i cant get the rdp xp color depth more than 16, i set -a 24 but its not changing, also xp is running in a vbox in ubuntu and as far as i know i have set all max video settings and installed guest additions
10:00
+ on the vm itself depth is 32
10:01
<alkisg>
Try freerdp
10:03
<VectorX>
not sure what you mean, coz the clients booting to windows where would freerdp come in ?
10:05
<alkisg>
!freerdp
10:05
<ltsp>
alkisg: Error: "freerdp" is not a valid command.
10:05
<alkisg>
!xfreerdp
10:05
<ltsp>
alkisg: Error: "xfreerdp" is not a valid command.
10:07
<alkisg>
!learn freerdp as http://www.freerdp.com/ is a new RDP implementation which is more actively maintained than rdesktop. Newer LTSP versions support SCREEN_07=xfreerdp <params>.
10:07
<ltsp>
alkisg: The operation succeeded.
10:07
<VectorX>
oh

crap im ending up with a black screen again, all i had was -a 32 -f host
10:27
same command just worked from the xterm(on server)
10:28killermike_ has joined IRC (killermike_!~killermik@2.26.103.219)
10:29
<alkisg>
Do your tests from the local xterm, not from the server
10:29
i.e. screen_07=ldm, login, ltsp-localapps xterm, test there
10:30killermike has left IRC (killermike!~killermik@2.26.89.23, Ping timeout: 252 seconds)
10:30
<VectorX>
btw where do i set the ubuntu session to Ubuntu 2D by default ?
10:30
<alkisg>
!gnome-classic
10:30
<ltsp>
alkisg: Error: "gnome-classic" is not a valid command.
10:30
<alkisg>
!classic-gnome
10:30
<ltsp>
alkisg: classic-gnome: To set classic-gnome as the default session instead of Unity in Ubuntu >= 11.04, put LDM_XSESSION="gnome-session --session=classic-gnome" in lts.conf
10:30
<alkisg>
...or something like that
10:30
<VectorX>
ok ill follow up
10:48
oh great im getting command not found from the client for xfreerdp
10:53
<alkisg>
You need to install that package in your chroot
10:53
<VectorX>
yeah working on that
10:53
<alkisg>
http://packages.ubuntu.com/search?keywords=freerdp
10:54
Did you try running rdesktop -a 32 from the local xterm?
10:54
<VectorX>
no
10:54
but this is better anyway right ?
10:55
<alkisg>
Yes, but package for 11.10 is old, freerdp 1.0 is out, so you'd need to search a bit to find it
10:55
(PPAs or somewhere)
10:55
And also why do you want bit depth > 16? This would just get it slower...
10:55
<VectorX>
for graphics, gimp etc
10:56
so far speed is ok but everything looks like the brown stuff
10:57
<alkisg>
Increase the "experience" parameter, not the color depth
10:57
Specify LAN there
10:57
man rdesktop etc
11:05
<VectorX>
i got -f -x l -a 24, but still 16
11:05
<alkisg>
VectorX: what I'm suggesting is that you should prefer 16
11:06
But also that should display good, not brown
11:06
<VectorX>
well this is for webgraphics design etc so with 16 you end up seeing grades of colors and its difficult to work with
11:07
<alkisg>
16bpp = 65536 colors, you shouldn't be seeing shades
11:07
But anyway if you can get the 24bit color depth from the server, but not from the client local xterm, you'd need to check the client color depth and graphics card
11:08
<VectorX>
perhaps, i am wondering if the issue is related to xp running in a vm, but ill try to organize another machine and test
11:08
thanks
11:10
<alkisg>
If you run rdesktop from the server and it works as you want it, and from the local xterm it doesn't, then you should be checking your client's graphics
11:10
Not your XP VM
11:10
np
11:11
<VectorX>
ill let me quickly try from the machine im currently on then its got a decent gfx
11:11

Howdy guys
18:01
Question - I have an ltsp server which is solid state, small form factor hosting fatclient images. long story short I had to rebuild the machine and now can not login after rebuilding as much as I could
18:01
i updated the ssh keys
18:01
however, i know I need to update the image. The LTSP server is debian, however the image I created / use is a NBD based image from Ubuntu
18:02
if i update the image on the debian server, will it break the NBD image?
18:31
<knipwim>
don't know

Is it about updating the fat ubuntu image under debian?
20:25killermike has left IRC (killermike!~killermik@2.26.103.43, Remote host closed the connection)
20:27
<msignor>
hey, sorry - no, i ended up just using my ubuntu client with an NFS mount to rebuild the image
20:28
my home folders broke :-(
20:28
i made sure it's in lts.conf and i can manually map the folder via nfs
20:28piet has joined IRC (piet!5510ce5b@gateway/web/freenode/ip.85.16.206.91)
20:29
<alkisg>
Are you using NFS_HOME in lts.conf?
20:29
<msignor>
(if you can clarify on the debian image update that would be appreciated, i just didn't want to risk it)
20:29
yes
20:30
<alkisg>
I think it should be fine, but I haven't tried it
20:30
<msignor>
its in /tftpboot/ltsp/i386
20:30
<alkisg>
!localxterm
20:30
<ltsp>
alkisg: localxterm: Any applications that you launch on a thin client actually run on the server. However, if in a client you run 'ltsp-localapps xterm', a local xterm will open, and any commands that you enter there will be executed locally on the client.
20:30
<alkisg>
From a localxterm, run getltscfg -a
20:31
To verify that it reads NFS_HOME
20:31
(or if you have ssh or other root access on the thin client, do it from there)
20:32
Btw, why did you decide to mix debian with ubuntu, instead of using just one of them?
20:33
Also I think debian prefers /srv nowadays
20:33
(for tftp)

<piet>
@alkisg: Hi alkisg, thank You for Your help the other day in finding out why ltsp is not using the dnsdomainname for hostname . . .
20:40
<alkisg>
piet: in greece we use Capital Letter for You, He, etc only for God, please don't do that :)
20:40
<piet>
You helped me in finding out that the error comes by configuration of dhcp . . .
20:40
<alkisg>
:D
20:41
Did you fix your dhcp?
20:41
<piet>
ok its becaus U are ZEUS for me ;-)
20:41
<alkisg>
Haha
20:41
<piet>
I found out , how it woks in dhcp . . .
20:43
<msignor>
ok. sorry just tried all this
20:43
<piet>
get-lease-hostnames true; is the line that has to be placed in dhcp3 . . .
20:44
<alkisg>
Nice :)
20:44
<piet>
that works fine and ltsp behaves like a "normal" workstation.
20:45
<msignor>
@alkisg it is properly pulling nfs_home
20:45
<piet>
How do U manage the automatic mounting of Server resources on the client?
20:46
well I stay back until msignor is done, ok?
20:46
<alkisg>
piet: no, it's usual in irc for many people to chat in parallel, don't worry about that
20:47
msignor: yet if you run `cat /proc/mounts`, you don't see it mounted?
20:47
Can you mount it manually in /mnt, from a root account on the client?
20:47
<piet>
wait . . .
20:47
<alkisg>
piet: did you try the EXTRA_MOUNTS option?
20:47
<msignor>
if i do a du -h i know that its not pulling the mount, i can try mounting it by hand though
20:48
ooh.. wait. i cant sudo
20:48
let me logout and login as root
20:48
<alkisg>
msignor: no
20:48
There are no password in the client, so you can't sudo
20:49
!SCREEN_02
20:49
<ltsp>
alkisg: SCREEN_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
20:49
<alkisg>
You can use that ^
20:52
<msignor>
i get an operation not permitted
20:52
i am root though
20:53
<alkisg>
What command do you give?
20:53
<piet>
@akisg: I try to place the mounts in lts.conf like <LOCAL_APPS_EXTRAMOUNTS=/mnt,/Daten,/video,/scripts> but they don't show up in cat /proc/mounts . . .
20:54
is there anything else to do but lts.conf-parameter?
20:55
they are supposed to get server-dirs to the client via sshfs, arent they?
20:55
<alkisg>
Yes
20:55
Can you also run `getltscfg -a` in a localxterm, like I told to msignor above?
20:55
<piet>
Im quit shure the list is comma separated . . .
20:56
<alkisg>
Yes, it is
20:56
<piet>
I have a fat client so a normal terminal should do it , isnt it?
20:58
<getltscfg -a> doesnt show anything . . .
20:58
<alkisg>
So your clients don't read your lts.conf
20:59
Can you put it to pastebin?
20:59
And, in which dir do you put your lts.conf?
20:59
<piet>
shure just a moment . . .
20:59
<msignor>
mount -t nfs IP:share mountpoint
21:04
<piet>
@ alkisg: its in http://pastebin.com/PWp3XnWa
21:10
<alkisg>
piet: the lines under 56, [screens], ALL apply to a client with hostname=screens
21:10
I mean that your lts.conf doesn't do what you want
21:10
<piet>
@ akisg : basically /var/lib/tftpboot/ltsp/i386/lts.conf is the dir where I put it in.
21:11
why not?
21:11
<alkisg>
But it doesn't matter now, you have another problem, that it doesn't read lts.conf at all
21:11
!tftp
21:11
<ltsp>
alkisg: tftp: Here's a page to help you troubleshoot TFTP problems in Ubuntu: https://help.ubuntu.com/community/UbuntuLTSP/Troubleshooting/TFTP
21:11
<piet>
ok I'll have a look
21:11
<alkisg>
Either in the client chroot, as root, or in another standalone machine, do:
21:11
sudo apt-get install tftp-hpa
21:12
tftp 10.160.31.10 -v -m binary -c get /ltsp/i386/lts.conf
21:12
***put your server ip there
21:12
This will tell you if your client can get lts.conf from tftp
21:12
Don't read the whole page, I just wanted to see the command
21:13
msignor: is mount.nfs available in your chroot?
21:13
<msignor>
should be... nothing changed i can check
21:14
<alkisg>
If you're getting access denied, check your nfs server export settings
21:14
What's the actual output of the command?
21:20
<msignor>
need to reboot.. i am testing in a Vm and it keeps hanging.
21:21
i am able to mount the nfs mount from my laptop to the sever
21:21
server*
21:22
<alkisg>
Are your ltsp clients in the same subnet as your laptop? (2-nic server or 1-nic server?)
21:22
<msignor>
yes, they are
21:22
i only have one subnet here
21:23
and from before - i have an embedded server, running just as a file / print host. (500mhz geode) it runs a debian distro voyage linux
21:24
however, i would like to use the /home folders, and actually through a prior conversation here in irc months ago, it was suggested to use nbd as it was faster and better supported long term
21:24
so i have been using the same image ever since
21:24
i changed the server to a new version and just never set up ltsp again until today
21:25
<alkisg>
Faster yes, better supported than nfs? I wouldn't say that, nfs is well supported too.
21:26
<highvoltage>
t/win last
21:27
<msignor>
heh, well trust me i prefer nfs as it avoids a bunch of un-necessary packages.. however it seems the nbd just worked better
21:27
now i cant just get it to work lol

alkisg: my test home lab has different boot times results today
22:08
strange things... server at first had nic2 not working (red light), then I made it work
22:08
and I discovered that clients (2 PC) have gbit lan
22:08
so boot time is really fast, login in 23"
22:08
(LDM)
22:08
the problem is: if I change computer, KDE finds that peripherals have changed and ask about them :(
22:13
ehm, if someone else has the answer... is welcome :) (fat clients of course)

@alkisg: I did all the tests but the last one. Everything seems ok but the version numbers in the file list, but that seems ok for me. There is no Test for a missing lts.conf file . . .
22:16
all the tests are around client not booting - but it boots . . .
22:18
besides that most of the configurational points in the lts are done like screen resolution. How can that be if the lts is not there?
22:18Parker955 is now known as Parker955_Away

@alkisg: maybe I did something wrong in checking the readability of the <lts.conf>?

hi, a question for you in the log 23:07
22:47
<alkisg>
(12:08:57 πμ) markit: the problem is: if I change computer, KDE finds that peripherals have changed and ask about them :( ==> KDE remembers the user peripherals and it asks the user?? Meh...
22:47
<markit>
yep, wondering if Gnome does the same
22:48
I've the feeling that recent development is more and more "single user centric"
22:48
(wayland is just one example)
22:49
<alkisg>
piet: so you can get lts.conf, but getltscfg -a still returns nothing?
22:50
<markit>
also I'm confused about flip-flop results in speed with ltsp... at the school boot was very slow, here at home (ltsp on KVM vm) was slow too. Today I tested and I had problems with the nic, after total switch off and cable change works, and I've found that clients are Gbit (green led on the switch), and boot works pretty well
22:50
I'll have a look again tomorrow
22:51
good night :)
22:51
<alkisg>
markit: from pxelinux to ldm, in a 3 year old lab, i got 12 seconds

22:52

markit: network + cpu speed matter the most for the boot times in ltsp clients
22:53
<markit>
client cpu or server cpu? (fat clients)
22:53
<alkisg>
piet: cat /etc/lts.conf, see if the file you want is there
22:53
Client cpu
22:53
(for both thin and fat, for boot speed)
22:54
<markit>
alkisg: so what cpu had your 12" clients?
22:54
(just curiosity, and in case you still remember)
22:54
<alkisg>
Some dual core cpu, I don't remember the details... it was 2 years ago, and the clients were 2 years old, so...
22:54
Nothing too expensive, just a new school lab
22:55
<markit>
interesting, sooner (or later... I'm always late with my projects...) I'll have i530 clients to test
22:56
hope KDE pepole will be interested in fix ltsp "no compliance", I have to write a list and post in dev list (and double cross my fingers)
22:56
good night again, your tips are always invaluables :)
22:57
<piet>
@alkisg: Damn it shows a file, but that looks like the one under /opt (with the hint to place it under /var . . .)
22:57
where is that defined?
