<Nickolia>
Hello guys. I have a LTSP server running approx 30 fat clients. All clients are using network printers Brother mfc-l2700 and everything is ok. But i've a problem with usb printer attached to fat client Canon LBP2900
08:29
On server Canon is printing and everything is ok. Cups installed on server and in chroot
08:30
<alkisg>
!print
08:30
<ltsp>
I do not know about 'print', but I do know about these similar topics: 'fatclient-printers', 'printer'
08:30
<alkisg>
!fatclient-printers
08:30
<ltsp>
fatclient-printers: You can publish printers on your network so that fat clients see them, by launching "system-config-printer" and selecting Server → Settings → Publish shared printers connected to this system
08:30
<alkisg>
Hmm no
08:30
!printer
08:30
<ltsp>
printer: Quick how-to: RCFILE_01="/usr/sbin/jetpipe /dev/usb/lp0 9100 &" in lts.conf, reboot client, then go to server's add printer dialog, and specify network printer → jetdirect → ltsp123.local
08:32
<Nickolia>
in lts.conf i have PRINTER_0_TYPE = U PRINTER_0_DEVICE = /dev/usb/lp0
08:33
How to connect printers i know. Ltsp is a system very admin friendly, but exactly with this printer i had a problem
08:35
Please tell where to dig. I spent on googling about 4 weeks for ltsp/printing/fat-clients before chating here
08:37
<alkisg>
There are two ways to share printers
08:37
One with jetpipe and one with cups
08:37
<Nickolia>
jetpipe and cups can live together?
08:38
<alkisg>
Yes but for different printers
08:39
So first, install the usb printer to the server and make sure it works there
08:39
Then move it to the fat client and ping me
08:39
<Nickolia>
Ok. Thanks. in a moment)

I've connected to server. installed drivers and print a test page. Now it is attached to fat client. The client was also rebooted
08:57
In terminal when i print "lsusb" i see him
08:57
from client
08:58

09:12
'm ready
09:16
<alkisg>
Nickolia: ok, do you have epoptes installed?
09:17
!epoptes
09:17
<ltsp>
epoptes: Epoptes is a computer lab administration and monitoring tool. It works on Ubuntu and Debian based labs with LTSP or non-LTSP servers, thin and fat clients, standalone workstations, NX clients etc. More info: http://www.epoptes.org
09:17
<Nickolia>
yes/, and client is nearby alongside with server. I run a test machine
09:18
<alkisg>
Cool
09:18
!vnc-edide
09:18
<ltsp>
vnc-edide: To share your screen with me, open Epoptes → Help menu → Remote support → Host: srv1-dide.ioa.sch.gr, and click the Connect button
09:18
<Nickolia>
Epoptes is a damn good tool- using it every day
09:18
<alkisg>
Thanks, I'm one of the devs :)
09:19
<Nickolia>
Wow) Thank you sir
09:22
open epoptes from server you mean?
09:22
<alkisg>
Yes
09:24
<Nickolia>
sorry for idiot question but where remote support is situated?
09:25
<alkisg>
You mean in which menu?
09:25
Help menu → Remote support
09:26
If you find it difficult, just run this in a terminal:
09:26
!vnc-dide
09:26
<ltsp>
vnc-dide: To share your screen with me, run this: sudo apt-get --yes install x11vnc; x11vnc -connect srv1-dide.ioa.sch.gr - this is a reverse connection, it doesn't need port forwarding etc.

09:31Statler has left IRC (Statler!~Georg@p5B30E54D.dip0.t-ipconnect.de, Remote host closed the connection)
09:39
<alkisg>
Nickolia: is that the correct model?
09:40
<Nickolia>
yeap
09:40
<alkisg>
Did it print?
09:40
<Nickolia>
maybe reboot printer
09:40
no print
09:40
<alkisg>
OK, try it
09:40
<Nickolia>
reboot done
09:41
you see? on server i connect it via script that downloads driver and register pninter
09:42
just installing printers it doesnt work
09:42
<alkisg>
That's why I prefer jetpipe
09:42
Because now you're supposed to install the printer to the server as well
09:42
And just tell it the ip address where it is
09:44
<Nickolia>
so what to do know?
09:47
<alkisg>
Nickolia: well...
09:47
From what I'm reading, this one ships with its own spooler
09:47
So basically there are three ways to proceed,
09:48
<Nickolia>
i have 7 of them)
09:48
all the same model
09:48
F*king Canon
09:48
<alkisg>
1) using jetpipe means you'd have to tell the canon spooler to forward to jetpipe on the client. I don't know how to do that because it's specific to that canon driver
09:48
2) using cups in the clients, means you'd first install the canon drivers to the chroot
09:49
or (3) connect the printer to the server, but since you have 7, scratch that
09:49
So maybe go with (2) in this case
09:49
<Nickolia>
ive installed it in chroot already
09:50
yesterday
09:52
<alkisg>
Nickolia: did it print?
09:52
<Nickolia>
nope
09:53
did client or printer need reboot to changes take effect?
09:56
<alkisg>
Did it print now?
09:57
<Nickolia>
negative
09:57
also no
09:58
<alkisg>
OK let's give it a reboot
09:59
<Nickolia>
you are very ัั‰ั‰ะด
09:59
cool)
09:59
<alkisg>
It's my job :)
09:59
<Nickolia>
for me its an unreal task. For now at least
10:05
<alkisg>
Nickolia: did you unplug the printer?
10:05
<Nickolia>
no
10:05
<alkisg>
It doesn't show up in lsusb
10:05
Can you reboot the printer?
10:05
<Nickolia>
i see
10:05
sec
10:06
done
10:07
when you type reboot- it doesnt reboot just logout
10:07
is it norm?
10:07
<alkisg>
If I type it as the user, yes
10:08
If i type it as root, no
10:09
Is it booting now?
10:10
<Nickolia>
it is showing that ccpd.service is stop job running
10:11
<alkisg>
ok hard-reboot it
10:11
press the reset button
10:11
<Nickolia>
done- loading
10:11
<alkisg>
Stupid printers, yeah :)
10:12
<Nickolia>
nobody is loving canon
10:13
Can i dissapeare for 10 minutes. Need to help to user
10:13
?
10:14
<alkisg>
Nickolia: I'm done :)
10:14
I think you have misconfigured your chroot cups.conf
10:14
So cups isn't working normally there
10:14Statler has joined IRC (Statler!~Georg@gwrz3.lohn24.de)
10:23
<Nickolia>
i need to reinstall cups?
10:25
<alkisg>
Reinstalling a package doesn't affect its configuration
10:26
So anyway this takes a longer time than I can give for free support.... if you ever end up needing professional support, ping me :)
10:26
<Nickolia>
Thank a lot for this. What price of support is?
10:27
<alkisg>
Let me PM you

<gizmo__>
hi all. I'm unable tp complete the ltsp-build-client --arch i386 due to dependency issues with mint-artwork-comon and mint-meta-core
21:01
any thoughts on how to resolve

!ltsp-pnp
21:02
<ltsp>
ltsp-pnp: ltsp-pnp is the recommented method to install and maintain LTSP for "usual" setups. Since it doesn't involve chroots, it requires little to no command line to maintain it. It automatically supports both thin and fat ltsp clients. https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
21:02adrianor1 has joined IRC (adrianor1!~adrianorg@177.132.217.38)
21:02
<alkisg>
gizmo__: try these methods instead of ltsp-build-client, they're more distro-agnostic
21:02
<gizmo__>
installing on linuxMint 18.3
21:02
<alkisg>
Which ubuntu version is that?
21:03
> Linux Mint 18.3 features Cinnamon 3.6, a Linux kernel 4.10 and an Ubuntu 16.04 package base.
21:03
OK, it's ubuntu 16.04, so you can use ltsp-manager
21:03
<gizmo__>
Its a distro based on ubuntu not a version of ubuntu
21:03
<alkisg>
It's not a distro
21:04
<gizmo__>
ok
21:04
<alkisg>
Distro means that it has its own repositories
21:04
But anyway, semantics
21:04
<gizmo__>
yes, but is makes heavy use of ubuntu repos also
21:04
will try ltsp-manager
21:04
<alkisg>
Except for a few packages,it's ubuntu 16.04, so it should work fine with ltsp manager
21:04
OK
21:05
There are 6 pages in the wiki, follow them in order

<alkisg>
Btw, we ltsp developers recommend ubuntu 16.04 mate instead of linuxmint, because mint is broken in quite a few places, but I don't have time to explain it in details now... :)
21:07
Ubuntu MATE is a normal flavor of ubuntu, while linuxmint tries to be a distro without being a distro, and it ends up breaking a lot of stuff

I dropped offline while typing a response to ltsp-manager. I am only able to find a deb package based on Ubuntu 14.04. there does not seem to be any updated versions of this package as far as I was able to look. Has anyone been able to get ltsp to work on Linux Mint 18.03 or even Mint 17?
22:02
<||cw>
gizmo__: it's going to be easier to use ubuntu mate 16.04 and just add whatever it is from mint that you find missing from ubuntu
22:02
which in my experience, mint just has extra bugs
22:03
<gizmo__>
I understand. I have not seen unresolved dependency issues with the dependencies in question actually already installed.
22:07
<||cw>
well, the current ltsp stable is only supported on ubuntu 16.04, so if you're not using that, you have a lot of work to do.
22:07
<gizmo__>
Been plugging away at this for a week now and discoveed just about every gotcha out there isn settng up an ltsp server. I tried opensuse edulife and after imaging the iso to flash drive many times using three differnt apps two on windows and unetbootin on linux iI could not create a bootable flahdrive image
22:07
<||cw>
including ubuntu 16.10 or 17.04.
22:08
<gizmo__>
The dependency issues I found are on both Mint 17 and 18
22:09
<||cw>
ltsp isn't just "a package". it's a complex integration of standard packages and custom modifications to them.
22:09
<gizmo__>
Found out the hard way that edulife will not install via usb at all. So I installed mint 17 and now 18 as I already had those images on flashdrive
22:09
<||cw>
so if you go changing any one piece, you have mod ltsp's integrations with distro aware conditional logic
22:11
<gizmo__>
I get that. The thing is that Mint has this ltsp-server and ltsp-server-standalone in its repos. I kind of expected them to install properly. The config issues I am prepared to deal with
22:11
<||cw>
if you're just starting with ltsp, you really need to use ubuntu 16.04 proper, even a netinst or minimal server OS install will do, but it needs to be 16.04
22:11
once you learn it how it works then work on porting to another distro.
22:13
take that up with mint. one of its flaws is that it pulls everything from ubuntu without any consideration if their changes affect any other packages
22:13
<gizmo__>
I am prepared to do as you suggest but I downloaded edubutu, which is rated as the best ltsp distro for schools. (I am doing this for a school.) Thing is, its based on ubuntu 14.04. Will give it a spin first then try the 16.04 if that fails
22:13
<||cw>
but also, if those are based on ubuntu 16.10+, ubuntu itself made changes that affect ltsp, and those are not yet resolved

Have to admit this was easier to do in the old days even though it was more manual. I have to wait each time until the end of the process to discover that it has failed with no means of recovering.
