<Guest67645>
hi. i have question again. clients are working how "fat"- clients.
08:44
i added line in config file lts.conf
08:44
[Default] LTSP_FATCLIENT=False LDM_DIRECTX=True
08:44
<alkisg>
3 lines, not 1, right?
08:45
<Guest67645>
no 3 lines one under another
08:45
<alkisg>
ok, and?
08:46
<Guest67645>
in log file i see: Starting to serve . Size of exported file/device is 1467543552
08:48
<alkisg>
and?
08:49
<Guest67645>
does clients download all image?
08:49
So it should be?
08:49
<alkisg>
No, it doesn't
08:49
It is exported, it's not downloaded
08:50
The clients reads only the parts that it needs each time, dynamically
08:51
<Guest67645>
ok. what will be ip on client? ip server?
08:52
<alkisg>
I don't understand the question
08:53
<Guest67645>
i see ip on the client 192.168.58.20. and ip on server the same
08:53
<alkisg>
How do you see the ip on the client, you opened gnome-terminal?
08:53
<Guest67645>
yes
08:54
<alkisg>
That terminal runs on the server
08:54
That's why you see the server ip
08:54
It is a thin client now, so the programs run on the server, not on the client
08:57
<Guest67645>
so, now i have thin client? right? because yesterday i saw ip the server on the client
08:59
<alkisg>
If you run `hostname` on that terminal, you should see the server's hostname, not the client's "ltsp123"
08:59
So yes you have a thin client now
09:05
<Guest67645>
thank you very much. you helped me a lot
09:06
<alkisg>
You're welcome... anyway, what is your server cpu and ram?
09:09
<Guest67645>
server works on kvm-virtualization and now have RAM 1Gb and CPU(s): 1
09:10
this options will be changed
09:10
<alkisg>
Eh ok, note that you'll need at least 500 MB for each client, so for 10 clients go for 5+ GB RAM on the server
09:12
<Guest67645>
ok. Thank you again

<markit>
is it me or linux-firmware-nonfree is missing in (k)ubuntu 16.04?
14:09
maybe has been renamed but can't figure out how
14:51
<alkisg>
markit, are you looking for broadcom? https://ubuntuforums.org/showthread.php?t=2325823
14:53
<markit>
alkisg: generic stuff, i.e. time ago amd radeon was not working properly without that
14:54
alkisg: I've changed my script to use apt-get instead of aptitude, I've a problem though
14:54
<alkisg>
markit, I don't think linux-firmware-nonfree had anything to do with amd in trusty
14:54
<markit>
aptitude a b c installs a and c even if b is missing, while apt-get aborts... Is the "-m" flag the right one? (just discovered why I miss a lot of stuff...)
14:54
<alkisg>
Here's the file list: http://packages.ubuntu.com/trusty-updates/all/linux-firmware-nonfree/filelist
14:55
<markit>
alkisg: but the entire package seems missing from their repo!
14:55
<alkisg>
Yes, it got split up to other packages
14:55
See the link I gave above
14:55ben_roose has joined IRC (ben_roose!~roose@roose.cs.wichita.edu)
14:56
<markit>
the list got from $ apt-file --package-only search /lib/firmware/ you mean? mmm so ODD
14:57
<alkisg>
No, for the ubuntuforums.org one
14:58
<markit>
yes, that post... I don't have a broadcom issue, just wanted to reduce hw issues with the firmware
14:58
btw, is "-m" the right flag for apt-get install?
15:00
mmm no, does not work too
15:05
<Guest67645>
i have one question. when works two thin client i see trafic 80-100Mbit/s
15:10mikkel has left IRC (mikkel!~mikkel@mail.dlvs.dk, Quit: Leaving)
15:19
<alkisg>
Guest67645: and the question is?
15:20
markit, apt-get purge --auto-remove $(dpkg-query -W -f '${Package} ' google-chrome-stable flashplugin-installer flashplugin-nonfree pepperflashplugin-nonfree)
15:20
That dpkg-query command only keeps the ones that actually exist
15:21
You need one similar to find which ones are there to pass to apt
15:23
<markit>
alkisg: clever solution (as usual ;P), I was changing the script to iterate through packages
15:28
<Guest67645>
question. it is real? if will be work four thin client. programs will be work very bad
15:41
<alkisg>
Guest67645: yes, that's why you need gigabit on the server, to handle more clients,
15:41
and that's why I was telling you to use fat and not thin...
15:43
!ltsp-pnp
15:43
<ltsp`>
ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
15:43
<alkisg>
That guide ^ is optimized for both thin and fat clients, with ubuntu-mate, which is light enough

<Guest67645>
if i will be used fat client and all clients will be write information in the programs how will be information save on server?
16:48
<alkisg>
Guest67645: LTSP fat clients are diskless and netbooted, the same as thin clients
16:48
The difference is that they use their own cpu and ram to run the programs
16:49
What are your client specs, which cpu and how much ram do they have?
16:51
<Guest67645>
pentium4 2GHz ram 1Gb
16:53
<alkisg>
It's ok for a fat client then
16:53
Use the tutorial I said, ltsp-pnp
16:53
And ubuntu-mate 16.04
16:54
<Guest67645>
ok. thank you

<rlyshw>
ah, I see. Yeah, we have one working(kinda) using berryterminal(http://berryterminal.com/doku.php) but it's old and not really well-supported.
19:05
<alkisg>
!raspberrypi

raspberrypi: (#1) Ubuntu/LTSP on Pi 2: https://help.ubuntu.com/community/UbuntuLTSP/RaspberryPi, or (#2) Debian/LTSP (with raspbian chroot) on Pi: http://cascadia.debian.net/trenza/Documentation/raspberrypi-ltsp-howto/, or (#3) unofficial Ubuntu/LTSP (with raspbian chroot) on Pi: http://pinet.org.uk/
19:05
<alkisg>
The first 2 ones are the ones supported by ltsp
19:06
Although it's really best to throw them away and buy something else :D
19:06
<rlyshw>
True lol I guess this project is just to determine the viability of deploying a bunch of pi thin clients.
19:07
We really only need them to do pretty basic office functions (email, document processing) and the berryterminal system seems to be stable enough for that.
19:07
<alkisg>
Have you tried working with a pi as your main pc?
19:07
It's worse than working with a mobile phone...
19:08
It's around 50 times slower than an i3
19:08
The beelink that I linked above, is 10 times faster than pi, and costs the same
19:09
<rlyshw>
I'll look for it on amazon too and let my boss know.
19:10
It seems like the thin client solution might be good enough for basic office purposes though
19:10
raspberry pi* solution

19:20
<markit>
btw, pi3 is much faster than pi2, in any case I think fat client is the way to go
19:35Faith has left IRC (Faith!~paty_@unaffiliated/faith, Quit: Leaving)
19:35
<alkisg>
pi3 is 1.5 times faster than rpi2, i3 is 50 times faster
19:36
There's absolutely no comparison... you can't even browse normally with a pi3
19:58
<markit>
that's true. Btw, the linked pc is "out of stock"
20:00
<alkisg>
It's just an example, no point in updating the link every once in a while...
20:00
It was 60 euros when I linked it

Hey so I'm running through the Ubuntu guide and I get to this part: ltsp-build-client --arch armhf --config /etc/ltsp/ltsp-build-client-raspi2.conf
20:18
and it seems to get stuck at I: Running command: debootstrap --arch armhf --foreign trusty /opt/ltsp/armhf http://ports.ubuntu.com/ubuntu-ports I: Retrieving Release
20:19
does this just take a while, or has something gone wrong?
20:19
<alkisg>
How come you're using trusty and not xenial, 16.04?
20:21
<rlyshw>
All of our servers still run on 14.04
20:22
We haven't gotten around to updating our scripts to use systemd
20:22
<alkisg>
I don't think 14.04 has the raspi2 kernel
20:22
Best use 16.04 for the pi chroot
20:22
<rlyshw>
ah, that would make sense
20:23
can I define that in the ltsp-build-client-raspi2.conf file?
20:26
although both the trusty and xenial ports list a armhf Release
20:26
http://ports.ubuntu.com/ubuntu-ports/dists/trusty/main/binary-armhf/
20:26
Still hanging even when I set --dist xenial
20:27
<alkisg>
trusty has an armhf release, but not a raspi2 kernel
20:27
It's not supposed to hang, though
20:33
<rlyshw>
i set --debug and it's just sitting at the I: Retrieving Release part
20:33
The debug stuff doesn't really seem to show anything more than the plugins it loaded.
20:34
<alkisg>
At that point, it's just debootstrap, not ltsp running
20:34
<rlyshw>
doing stuff behind the scenes? Am I just being impatient?
20:34
<alkisg>
You can run ps aux and see the debootstrap command, and run it for yourself without ltsp
20:34
You can also try plain debootstrap without armhf emulation
20:35
It may be an internet issue, or you being impatient,or slow cpu ==> very slow armhf emulation
20:35
<rlyshw>
ps aux | grep debootstrap
20:35
gives
20:35
wget -q -O /opt/ltsp/armhf/var/lib/apt/lists/partial/debootstrap.invalid_dists_xenial_Release http://ports.ubuntu.com/ubuntu-ports/dists/xenial/Release
20:35
and another two running debootstrap processes
20:36
<alkisg>
Invalid dist doesn't sound proper
20:36
<rlyshw>
definitely seems off
20:36
<alkisg>
Maybe you have an old debootstrap?
20:36
E.g. disabled trusty-updates?
20:36
Really though, pi's are not worth the time...
20:36
<rlyshw>
debootstrap --version debootstrap 1.0.59ubuntu0.6
20:37
<alkisg>
...sounds recent...

21:30
<rlyshw>
alright so I figured out the issue
21:30
stale proxy settings in /etc/wgetrc messed up debootstrap
21:31
and now the chroot apt-get update stuff is failing because that proxy isn't set right. I'll just chroot in and manually run the apt-get stuff.
