What's a good book on LTSP?
00:45
<johnny>
are there any?
00:45
the documentation in the topic is all i know about
00:46
or the documentation on the ubuntu wiki
00:46
ball, ltsp is evolving too fast to write a book about it atm i think..
00:46
any book would be obsolete by the time it came out
00:46
a book written 3 months ago wouldn't have mentioned the new local applications support for example
00:52kharloss has joined #ltsp
00:55
<ball>
Hmm... I suppose that makes sense.
01:05
<johnny>
perhaps in the next year it will be stablilized somewhat
01:05
i'd suggest reading the docs in the topic
01:06
g'night

what is the advantage of using LTSP 5 and not the LTSP 2
08:26
what is the advantage of using LTSP 5 and not the LTSP 4.2
08:31alkisg has quit IRC
08:33
<Nubae>
for one, LTSP 5 is supported and ltsp 4.2 isn't
08:35alkisg has joined #ltsp
08:36
<petre>
sound is much easier to get working in LTSP 5
08:36
Flash, too
08:36
<Nubae>
and local devices
08:36
<petre>
4.2 supported local devices
08:37
but Nubae is right that the code has been refined since 4.2
08:37
5 also will have better support for new graphic cards/chips in the clients
08:37ltsppbot has quit IRC
08:38
<petre>
5 also is now getting support for local apps
08:38
<Nubae>
then there is local apps, fat client, ltsp-cluster
08:38
:-)
08:38
<petre>
so, 4.2 is arguably simpler, but by that same token, it is less capable
08:39
<Nubae>
I guess the biggest advantage is that ltsp 5 is now an upstream project as opposed to a distro
08:39
<petre>
yes, much more easily applied to whichever distro you want to run
08:43ltsppbot has joined #ltsp

09:02
<petre>
WeeD_, not sure, I'm not a debian person
09:02
the best person to ask would be vagrantc, but he's on the west coast of the US, meaning he's probably still sleeping
09:02
<WeeD_>
ok.. but i dont know purge ltsp 4.2 any distribuiton
09:03
ok.. but you dont know purge ltsp 4.2 any distribuiton?
09:03
<petre>
with 4.2 much/most of the code was contained in /opt/ltsp
09:03
you might be able to just remove that
09:04
<WeeD_>
rm -r /opt/ltsp resolved?
09:04
<petre>
but I think the dhcp stuff is different, so you may want to remove the dhcpd package
09:04
<WeeD_>
ok
09:04* petre is kinda guessing here
09:04
<WeeD_>
but my server LTSP is dhcp server too
09:04
petre
09:05
<petre>
oh, then don't remove dhcpd package
09:05
<WeeD_>
ok
09:05
thanks boy
09:05
<petre>
do you have two NICs in your server?
09:06
<WeeD_>
09:06
ex 192.168.1.100 to 192.168.1.200
09:08
<petre>
in ltsp 5, some of the stuff that used to be in /opt/ltsp gets moved to being under /tftp, which varies by distro
09:08
that may be more difficult to make work with a single NIC in 5
09:08
It is for Fedora, which I use; not sure about Debian
09:09
<WeeD_>
ok

petre: pong
16:14kharloss_ has joined #ltsp
16:14
<petre>
stgraber, you mentioned putting NX onto a laptop or netbook and connecting over wireless to the LTSP server
16:14kharloss_ has quit IRC
16:15
<petre>
was that a custom image on the client? or just a stock version? or something else?
16:15kharloss_ has joined #ltsp
16:16
<johnny>
you could use any distro minimal install to do that
16:17
after installing NX of course..
16:18
<stgraber>
yeah, we have a minimal Ubuntu for that
16:19
basically a debootstrapped system with X and an init script to start X and NX
16:21radoeka has quit IRC
16:25kharloss has quit IRC
16:35
<petre>
stgraber, is that documented anywhere?
16:38
<stgraber>
petre: nope, we don't have any customer using it so it was just quickly done as an experiment and not documented. It's basically: debootstrap Ubuntu 8.10 on a ext3 usb key, install ubuntu-minimal and ubuntu-standard, install Xorg, install NX (binary taken from nomachine), make rc.local to do a dhcp request and start X+NX. Then setup grub and you're done.
16:38
it's very similar to a LTSP chroot actually
16:39
<petre>
ok, that gives me an outline of the steps, which is good enough
16:39
tx
16:54Hyperbyte has joined #ltsp

<petre>
ok, back to printing: I cannot telnet to port 9100 on the client that has the printer attached
16:56
any suggestions what to look at?
16:57kharloss_ has quit IRC
17:01
<petre>
wish there was a 'lsusb' command on the clients
17:02
<jammcq>
so put one there
17:04
<petre>
hey jammcq!
17:04
<jammcq>
he petre
17:04
<petre>
actually, I did, right after I typed my lament
17:05
and it sees the printer
17:05
should I see jetpipe or similar in ps -ef on the client?
17:06
I suspect that is what is missing?
17:06
<jammcq>
I have no clue
17:06
i've been out of the loop too long
17:06
<petre>
I fooled around with jetpipe but that was at least year ago, probably longer
17:07
<stgraber>
jetpipe being a deamon it should be running yes
17:07
I have never used it though
17:07
<petre>
hmm, I have a /usr/bin/jetpipe
17:08
but when I try to load it I get an error:
17:08
"File /usr/sbin/jetpipe, line 40, in <module> import serial
17:09
ImportError: No module named serial"
17:09
<stgraber>
do you have python-serial installed ?
17:09
or whatever it's called in fedora
17:10
<petre>
no, and yum lists no such package
17:10
I've got a setserial package
17:10
for setting serial ports
17:10
but that's probably not what it's looking for
17:11
<stgraber>
and pyserial ?
17:12
<petre>
ah, pyserial looks promising
17:12
<stgraber>
yeah, pyserial is the upstream name for python-serial
17:12
ubuntu/debian tries to call python-<the thing you import> instead of using the upstream name for all python modules
17:13alkisg has quit IRC
17:13
<stgraber>
but the upstream for python-serial is pyserial so it should be what you need
17:14
<petre>
why don't they just use the upstream name?
17:15
<stgraber>
it's easier to list all the python packages on the system looking for python-*, I suspect python-support and python-central (things used to handle python modules) also use sort of need that naming
17:15
s/use//
17:16
<petre>
hmm, still failed, same error

<Guevara>
folders of users
19:11
users that the system
19:11
<jammcq>
umm, that's a basic Linux question. Maybe you need quotas

19:12
yes, i look this http://beginlinux.com/server_training/126-linux-terminal-server/1057-managing-users-in-ltsp

why?
19:12

hi
20:43
I'd like to know how to install soft under ltsp-thin-client
20:44
<vagrantc>
!release
20:44
<ltspbot>
vagrantc: "release" is please mention the linux distro and release you're using :)
20:45
<lbs>
ubuntu 8.10
20:46
Now,when I using ltsp-update-image,it doesnt work
20:46
I was confused with the /opt/ltsp/i386 and the original system.
20:48
I changed the /opt/ltsp/i386/etc/rc.local file,but it does not work.
20:49
could you help me/
20:51
<vagrantc>
lbs: so you edited /opt/ltsp/i386/etc/rc.local and ran ltsp-update-image ?
20:51
<lbs>
yes
20:52
I just want to run x11vnc and let the thin-client-manager work
20:52
<vagrantc>
did that give you an error?
20:52
<lbs>
It gives nothing.
20:53
and I cannot connect to thin-client's x11vnc.
20:53
in thin-client-manager.
20:54
but in ubuntu 7.10,I did it.
20:55
I don't know whether the /opt/ltsp/i386/etc/rc.local run when logon into the thin-client.
20:55
<vagrantc>
i don't either
20:56
i use debian, which has a different init system from ubuntu
20:56
<lbs>
You met the same problem?
20:58
<vagrantc>
never had any such problem, debian works very differently
20:59
<lbs>
oh.
20:59
<vagrantc>
no ltsp-update-image, different init system, and i've never tried to use x11vnc
21:00
<lbs>
why?You don't need to manage the thin-client?
21:00
or use iTALC or thin-client-manager?
21:08
Who use ltsp under ubuntu?
21:13
<vagrantc>
lbs: debian still uses NFS rather than NBD, so ltsp-update-image isn't needed.
21:14
lbs: simply chroot /opt/ltsp/i386 apt-get install YOURFAVORITEPROGRAM
21:18
<lbs>
but some soft has a service daemon,how can I run it under thin-client?
21:18
such as iTALC,a kind of classroom management tool.
21:19
It has a service daemon and use the port 5900
21:20
If I didnot apt-get install it under chroot,I also can run it manually under thin-client.

lbs, thin-client-manager is broken
21:44
and the x11vnc part will be removed
21:45
it is broken.. and will stay broken.. italc is the preferred solution

johnny:but Now the thin-client-manager is very simple.
22:10
<johnny>
it will be simpler :)
22:10
if you want to fix it.. i suppose people will be happy, but there is nobody currently interested in fixing the x11vnc problem, as the program is not maintained by anybody
22:22
<lbs>
I see.
22:23
but how can I install iTALC ON THIN-CLIENT?
22:23
I have read the wiki help
22:23
and I have some questions
22:24
johnny:How can I make my start_ica script to run when thin-client user logon?
22:25
Now,when the thin-client user logon. I manaually run the script start_ica.
22:25
and in the iTALC master interace,
22:26
I cannot connect to thin-client use the localhost:11168.168 is the thin-client ip.
22:29
<johnny>
i have no idea
22:29
i've never used either
22:29
please don't private message somebody
22:29
unless they asked you to do so
22:29
other people here use italc, but i assume they are all asleep
22:30
try coming back later
22:30
altho.. the weekends aren't the best time to get help either
22:31
usually the weekdays, during the daylight hours of usa and europe
22:31
i know many things about ltsp .. just not at all related to its educational usages :)
