hi, anyone has experience with ACL? I've created 2 dirs under /srv, one that is rw for teachers but read only for students, the other is rw for everyone
07:06
things go very well if you CREATE the file there (in any of them), the ACL is respected
07:06
but if you COPY file there, then you don't have the default permissions applied
07:06
any clue/solution?

(the package)

<Pingu>
I tried
09:09
not exactly what I need
09:09
I have a tablet running Ubuntu 10.10
09:09hahlo has joined #ltsp
09:10
<Pingu>
that starts up directly to a web app running on Firefox
09:12
The tablet has a touch screen
09:12
<robehend1>
doesn't the mouse pointer follow the touch screens input/
09:12
<Pingu>
I want the mouse to be functional but invisible
09:12
Is there a way to set the poiner as invisible?
09:13
<robehend1>
make an invisible mouse graphic and apply it to your current theme?
09:13
it'd still "be there", but just an empty png
09:13
or whatever format
09:13
<Pingu>
Unlutter hides the mouse while idle, but the pointer shows up when I touch the screen
09:13
OK
09:14
how do I do that?
09:14ogra has joined #ltsp

hey there, anybody have a problem getting lts.conf to be paid attention to?
09:57
<Gadi>
tastle73: syntax error?
09:57
<tastle73>
how can I debug that?
09:57
<Gadi>
can you log in at a thin client?
09:57
<tastle73>
I am trying to get a local printer recognized
09:57
yes
09:57
I am on it presently
09:58
<Gadi>
log in, open a terminal, run:
09:58
ltsp-localapps xterm
09:58
in the xterm that pops up, type:
09:58
getltscfg -a
09:58
<tastle73>
I am ssh'ed in
09:58
<Gadi>
ssh'ed into the client?
09:58
<tastle73>
yep
09:58
<Gadi>
ok
09:58
then just: getltscfg -a
09:58
<tastle73>
nothing
09:58
blank
09:58
<Gadi>
sounds like you have no lts.conf
09:59
or it is not grabbing it
09:59
<tastle73>
oh but I do :)
09:59
<Gadi>
where did you put it?
09:59
<tastle73>
/var/lib/tftpboot/ltsp/i386
10:00
<Gadi>
and you only have the one chroot, right?
10:00
<tastle73>
I have an ltsp_old and new
10:00
under /opt
10:00
<Gadi>
so you have: /opt/ltsp
10:01
and: /opt/ltsp_old
10:01
<tastle73>
yes
10:01
<Gadi>
ok
10:01
distro?
10:01
<tastle73>
ubuntu
10:01
<Gadi>
10.04?
10:01
<tastle73>
yes
10:01
<Gadi>
ok
10:02
make sure that: grep tftp /etc/inetd.conf returns nothing
10:02
and then check: /etc/default/tftpd-hpa
10:02
<tastle73>
nothing in inetd.conf
10:03
<Gadi>
what do you have for TFTP_DIRECTORY=
10:03
<tastle73>
/var/lib/tftpboot
10:03
<Gadi>
hmm... ok
10:03
so far so good
10:03
did you change perms on lts.conf?
10:03
<tastle73>
no
10:04
<Gadi>
from the client, can you do:
10:04
tftp server
10:04
and at the prompt:
10:04
get /ltsp/i386/lts.conf
10:04
quit
10:04
and see if it retrieves it ok
10:04
<tastle73>
yep it did
10:05
<Gadi>
on the client, can you cat /etc/lts.conf
10:05
is it what you expect?
10:05
<tastle73>
yes
10:06
[default]
10:06
LDM_DIRECTX=True
10:06
LDM_SYSLOG=True
10:06
SCREEN_02=shell
10:06
SCREEN_07=ldm
10:06
LOCALDEV=True
10:06
PRINTER_0_DEVICE = /dev/usblp0
10:06
#PRINTER_0_TYPE = U
10:06
#PRINTER_0_PORT = 9100
10:06
<Gadi>
and still nothing from: getltscfg -a
10:06
<tastle73>
yep
10:07
<Gadi>
weird
10:07
well, the commented options can be deleted
10:08
not used in version 5
10:08
but, that shouldnt cause the file not to be read
10:08* Gadi is at a loss
10:08
<tastle73>
thanks
10:08
<Gadi>
there must be something wrong with the text file
10:09
try recreating it

sup guys
10:41
running a test 10.04 server, and I am having problems with tftp
10:41
in syslog, I see the following: in.tftpd[PID]: tftpd: read: connection refused
10:42
RRQ from 192.168.46.1 filename /ltsp/i386/pxelinux.0
10:42
why is tftp denying requests?
10:42Pingu has quit IRC
10:42
<_UsUrPeR_>
I have attempted to run in permissive mode (-p option) no dice
10:42
there's no firewall
10:45
<LedHed>
_UsUrPeR_, permission issue on /ltsp/i386/pxelinux.0?
10:45
<_UsUrPeR_>
LedHed: naw, that's all default, and appears ok compared to another server I have running
10:45
I think this is a network issue with a virtual server. (this is a virtual server)
10:46
<LedHed>
can you tftp to it directly?
10:47
I mean, from another computer, can you connect and D/L files?
10:55dobber has quit IRC
11:11
<_UsUrPeR_>
good question
11:11
lemme try that
11:18
aww screw it
11:18
im making a new server
11:18
<LedHed>
lol.
11:18
Virtual?
11:22
<_UsUrPeR_>
yeah, kvm
11:29highvoltage has quit IRC

11:34shawnp0wers has quit IRC
11:36
<_UsUrPeR_>
tastle73: that file belongs in /var/lib/tftpboot/ltsp/i386/
11:36
that may be a problem :)
11:38
<markit>
hi, anyone has experience with ACL? I've problems of permissions when you copy files on dir that has a default policy, that seems ignored
11:38
<tastle73>
well, if it is in ~tftpboot it is not picked up
11:40
<_UsUrPeR_>
tastle73: well I can nigh-guarantee you it will not be seen in it's present position.
11:40
tastle73: to qualify that above comment, are you running ubuntu?
11:40
<tastle73>
iyes
11:40
<_UsUrPeR_>
markit: what OS are you running?
11:43hahlo has quit IRC

I put lts.conf in /opt/ltsp/i386/etc and ran ltsp-update-image -a i386 and it worked
11:44
did not work until I did so
11:44alkisg has joined #ltsp
11:46
<_UsUrPeR_>
sorry, I have been attending to something locally
11:46
ok, so -
11:47
first, mv /opt/ltsp/i386/etc/lts.conf /var/lib/tftpboot/ltsp/i386/lts.conf
11:47
next, ltsp-update-image --arch i386
11:48
tastle73: how are you testing your lts.conf?
11:48
are you attempting to enter your shells?
11:48
I.E. screen_02 etc?
11:55
<tastle73>
ssh to the box and typing getltsconfig -a
11:58
does it matter that my dhcp server is on another box?
11:59
<_UsUrPeR_>
tastle73: that is a definite possibility, yes
12:01
<Gadi>
tastle73: are you using dnsmasq?
12:01
<tastle73>
no
12:01
<Gadi>
next-server?
12:03
<tastle73>
yes

12:04
<Gadi>
you may want to try adding to the kernel command line in pxelinux.cfg/default: nbdroot=<ip>:2000
12:04
<tastle73>
option root-path "10.0.0.9:/opt/ltsp/i386"
12:04
<markit>
_UsUrPeR_: kubuntu 10.10
12:05
<Gadi>
root-path does not apply to nbd
12:06
<_UsUrPeR_>
markit: so are you saying that you cannot create files in the user's directory?
12:08
<tastle73>
so I don't need root-path?
12:13
<_UsUrPeR_>
tastle73: I believe you still need a root path
12:13
it would look like /var/lib/tftpboot/
12:13
<markit>
_UsUrPeR_: I've to run, I'll be back in a hour
12:13

12:13

(I can create, only copied files loose permissions)
12:14markit has quit IRC
12:18
<Gadi>
tastle73: right - that's only for NFS
12:21
<alkisg>
Some weird NIC boot roms need root path (even if unused with nbd) otherwise they refuse to netboot
12:21
tastle73: paste the if/boot filename directives, those are used to fetch lts.conf
12:23
<tastle73>
option root-path "10.0.0.9:/var/lib/tftpboot";
12:23
next-server 10.0.0.9;
12:23
if substring (option vendor-class-identifier, 0, 9) = "PXEClient"

12:24
<alkisg>
What's that "/lts/vmlinuz.ltsp"?
12:24
Are you using it?
12:24
Due to that, your lts.conf is expected to be in /var/lib/tftpboot/lts/lts.conf
12:25
<tastle73>
I know that's wrong sorry
12:25
<alkisg>
Here's a correct example: /usr/share/doc/ltsp-server/examples/dhcpd.conf
12:25
So if you fix that line, you'll correctly get lts.conf
12:29
<tastle73>
thanks everybody, I am trying it presently
12:35
it works
12:37
<_UsUrPeR_>
ok, I am still having an issue with tftpboot on this server. I am capable of booting the client, and getting to tftp...
12:37
this is a newly-installed ubuntu 10.04 installation
12:38
with no changes made to the server.
12:38
aside from dhcp to get it started, and the creation of an ltsp image
12:38
<tastle73>
new problem: users are having to wait 2 minutes until a thin client will allow them to log in
12:38
<alkisg>
_UsUrPeR_: https://help.ubuntu.com/community/UbuntuLTSP/Troubleshooting/TFTP
12:38
bbiab
12:39
<tastle73>
they can type user and password but it rejects the logon
12:39
this is in the thin client's log:
12:39
nbd9: unknown partition table
12:39
nbd9: NBD_DISCONNECT

12:40
<tastle73>
yes it is
12:40
I am using ldap as the auth backend
12:41
<Gadi>
then run: sudo ltsp-update-sshkeys; sudo ltsp-update-image --arch i386

random, semi ltsp related question. if I create a desktop launcher, is there a quick bash script to copy it into the desktop of all my users? I'm thinking something like.. sudo cp ~/Desktop/launcher.desktop /home/*/Desktop/

anyway i can check and enable them? driving me crazy
14:12
<robehend1>
yeedl: put things like SCREEN_08 = shell in your lts.conf
14:13
<yeedl>
clear
14:13
i placed SCREEN_06 = shell and got a blank when i went to ctrl-alt-f6
14:14
<robehend1>
if i'm not mistaken, arent we supposed to use numbers above 7/
14:15

14:22
oddly, if the users log in to a icewm session, they can get in no problem
14:22
<Gadi>
ah
14:23
do this:
14:23
!disable_compiz

hey all. Can someone tell me the naming convention for mac addresses pertaining to /var/lib/tftpboot/ltsp/i386/pxelinux.cfg ?
14:46Da-Geek has joined #ltsp
14:46
<_UsUrPeR_>
I created a file called 00e0c5 expecting the client to pick it up, but no dice
14:47Da-Geek has quit IRC
14:49
<Gadi>
_UsUrPeR_: 01-aa-bb-cc-dd-ee-ff
14:50
<_UsUrPeR_>
gadi: gotcha
14:50
Gadi: I am seeing the client check for something completely off-base for the rest. Where is it getting C0A80114 from?
14:51
that's nowhere close to the actual mac address
14:51
<Gadi>
hex version of IP
14:51
<_UsUrPeR_>
haha oh wow
14:51
ok
14:51
<Gadi>
192 = C0
14:51
etc
14:51
<_UsUrPeR_>
IP, not mac?
14:51
interesting
14:51
<Gadi>
well, actually no
14:51
but, you know what I mean
14:51
yeah
14:51
<_UsUrPeR_>
I believe I do, yes
14:51
<Gadi>
it looks for MAC
14:52
then network
14:52
<_UsUrPeR_>
ok, gotcha
14:52
so that's the hex of the MAC?
14:52
<Gadi>
so, you can make a file that applies for the 192. network
14:52
or the 192.168.
14:52
etc
14:52
mac is already hex
14:52
it is:
14:52
01 (for ethernet)
14:53
then mac
14:53
with:
14:53
s/:/-/

FYI: taking off @5 EST (~20 minutes)
15:34
<markit>
I will tell you briefily my problem if you have 5 minutes and you can give me a tip or direction
15:34
<_UsUrPeR_>
I think I got it last time
15:34
<markit>
_UsUrPeR_: I've created 2 dir under /srv, one I want to be R/W for everyone, teachers and students
15:34
the other must be RW for teachers and R for students
15:34
everything is fine if I create the files directly there
15:34
(by teachers or students)
15:35
but if a teacher creates a file in his own home and THEN copies it there
15:35
the ACL seems not applied
15:35
(in R/W students have only R access)
15:35
am I missing something? is ACL too weak for real usage?
15:35
I'm so depressed :(
15:35
<_UsUrPeR_>
oh man
15:36
I had to deal with this one
15:36
<markit>
(this sums up to a long list of "minor issues" that have took a lot of time and energy so far in teh setup)
15:36
<_UsUrPeR_>
there is a specific name for it
15:36
I believe it's called a "sticky bit" or something
15:36
<markit>
mmm this has nothing to do with ACL, I've tried this in the past
15:36
before knowing the ACL power, that is exactly what I need exept for the copy thing
15:37
I'm surprised that in #ltsp so few has this problem, or has solved with acl
15:37
(I'm open to any efficient and clever solution to the problem itself, in any way, being with ACL or without)
15:38
<_UsUrPeR_>
ok, so how do these people traverse to their directory?
15:38
is there a simlink in their home dir?
15:39
how do they access their shares?
15:41
<markit>
they go to /srv/shared
15:41
using dophin
15:41
(the kde file manager)
15:42
so you create a file, open dolphin, select it, right click - copy, go to /srv/shared, then paste
15:42
then go to the terminal and have a look at extended attributes ACL, and you find that students group has "r" only
15:42
while if you directly create the file in /srv/shared you get correctly RW
15:43
<_UsUrPeR_>
who owns the /srv/shared dir?
15:43
<markit>
so if you create a file, the default policy is applied, if you copy one there, no (probably keeps the original ones, or mixes, I had no time to check properly, I can do tomorrow)

I fixed my problem, and I think I spoke to someone in #ubuntu-server to fix it.
15:44
<markit>
thanks in any case :)
15:45
ok, thanks for the tip, I will try
15:45
<_UsUrPeR_>

Hi--I want to add everyone on my server to the fuse group so that they can access usb drives on the thin clients.
17:23
Can I just "sudo adduser /home/* fuse"?

OK, Does it look like this script might work? http://nixcraft.com/linux-software/8498-add-multiple-users-group.html

Well, I do understand editing a text file. I'll try /etc/group/ and adding users on that page and restarting...
