<Pyasv>
Hi, I need help! When connecting to a thin client, the / home partition is not visible. What you need to register in prints lts.con?
12:22
<alkisg>
Pyasv: hmm, more explanation is needed. Start with distro/version
12:24
<Pyasv>
Description:Ubuntu 16.04.4 LTS
12:25
ltsp-client 5.5.7-1
12:25
<alkisg>
OK, what are your client specs, how much ram do they have?
12:25
<Pyasv>
ltsp-server 5.5.7-1
12:26
<alkisg>
How much RAM do your clients have?
12:26
And what CPUs?
12:26
<Pyasv>
2gb
12:26
<alkisg>
(so that we see if you want to use thin or fat clients)
12:26
OK, then you want to use fat clients, not thins
12:27
Did you follow some tutorial to set up ltsp?
12:28
Do this: sudo ltsp-info | nc termbin.com 9999
12:28
And tell us the output
12:29
<Pyasv>
No LSB modules are available. http://termbin.com/d8i4
12:29
<alkisg>
There are many ways to run ltsp
12:29
You are not using a good way. You have a thin client chroot, while your clients are good enough to use a fat chroot or a chrootless ltsp
12:30
<Pyasv>
My task. There where the weak processor to use the thin client.
12:30
<alkisg>
The clients are weak and you want to use them as thin clients?
12:30
Which CPU model do they have?
12:31
<Pyasv>
atom
12:31
d525 1.8
12:31
<alkisg>
Eh, they're not that bad, they would probably run better as fat clients
12:32
So anyway about your question. If you have thin clients, and you open the file manager, you see the server /home
12:32adrianor1 has joined IRC (adrianor1!~adrianorg@187.115.107.234)
12:32
<alkisg>
But of course localapps (if you use those) work on the client and don't see /home
12:32
Open a terminal on the client and run: ls /home
12:32
Do you see the server home?

12:36
<alkisg>
Pyasv: I see that we have language issues. Do you want me to help you with VNC?
12:36
(remote desktop)
12:37
<Pyasv>
Yes, my English is bad
12:38
<alkisg>
For me to help you with VNC, run this: sudo apt --yes install x11vnc; x11vnc -connect 193.92.203.16
12:39
<Pyasv>
in the console writes "No directory, loggining in with HOME=/"
12:40
no, I want to boot into a thin client on a computer
12:40
<alkisg>
Yes, I understand, but I can't help you without screen sharing, because of the language
12:41
VNC will allow me to see what is wrong with your server setup. The fix is on the server, not on the client.
12:44
<Pyasv>
You want to connect to me on VNC?
12:44
<alkisg>
Yes
12:45
<Pyasv>
Good. 5 minutes

12:50
<derick_>
on my client internet is not working. I have manaually change nameserver to 8.8.8.8. Is there a better way to make it work?
12:50
<alkisg>
derick_: see the newer ltsp version
12:50
!install
12:50
<ltsp>
install: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
12:51
<alkisg>
Pyasv, you don't need to give me your ip and you don't need to run vnc. Run this: sudo apt --yes install x11vnc; x11vnc -connect 193.92.203.16
12:52
<derick_>
alkisg : setup part is right I think. Its a networking related issue . ping 8.8.8.8 works | nslookup google.com does not | nslookup google.com 8.8.8.8 works
12:52
<alkisg>
derick_: the newer ltsp has fixed a lot of networking issues
12:53
You obviously have a misconfigured dns, and I've uploaded fixes for that.
12:53
*resolv.conf
12:54
Pyasv: did you close it? I lost the connection
12:54
Run it again if you want
12:57
<derick_>
alkisg : I am using ltsp-server package not ltsp-server-standalone.
12:57
<alkisg>
derick_: ok, the code is there too
12:59
<derick_>
alksig : but commands like ltsp-config dnsmasq --enable-dns does not work.
12:59
<alkisg>
derick_: did you add the ppa, as the wiki says?
13:00
Pyasv: so, you're using fat clients,
13:00
and, with lubuntu in the chroot, and with an old version, that has problems with XSESSION,
13:00
so, you had to use LDM_XSESSION there which isn't a good thing to do. The correct thing to do would be to install a newer, fixed LTSP
13:01
Pyasv: so if you want to use 16.04, I suggest you install LTSP using this page: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp?action=recall&rev=30
13:01
Pyasv: if you want 18.04, this page:
13:01
!install
13:01
<ltsp>
install: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
13:03
<Pyasv>
Thanks, I'll try
13:03
<alkisg>
You're welcome

14:03

Yup. Now I am shutdown client from epoptes as well.

14:23
<Hyperbyte>
alkisg, I'm not on the mailing lists
14:24
<alkisg>
OK
14:25
<Hyperbyte>
But that's good news.
14:25
I'm not feeling lucky yet to roll it out. :-D But maybe in a few months.
14:26
<alkisg>
Hyperbyte: sure; now it's the testing + bug solving period; later on it will be more stable but without bug solving; whatever suits you best :)
14:27
<Hyperbyte>
When I migrated from 14.04 to 16.04 I think I spent a few months fixing all problems my users encountered
14:29
But that's mainly because of all the Ubuntu stuff.
14:30
Also, since the thin clients we're using are over 8 years old now, I might try to convince the company boss to buy beefier machines and start using fat clients instead of thin.
14:31
<alkisg>
Yey! The last thin client installation will RIP :D
14:31
<Hyperbyte>
It's tough though to find small, fanless clients that support dual monitor.
14:31
Far from the last. :-D
14:31
<alkisg>
Really? They don't have 2 outputs, like hdmi + vga?
14:31
!cheap-client
14:31
<ltsp>
cheap-client: https://www.gearbest.com/tv-box-c_11262/?attr=2081-1279
14:31* alkisg looks...
14:31
<Hyperbyte>
At the radio/tv station in Dordrecht we'll still be using thin clients, but that's a matter of budget.
14:32
alkisg, I don't want VGA. I'd want HDMI+HDMI.
14:32
<alkisg>
Ah ok then. Maybe you could find hdmi+dvi, if you can settle with that...
14:32
<Hyperbyte>
Maybe. I'll have to do some research when the time is there.
14:32
It'll be in a year or so at earliest, so who knows what's on the market then.
14:33
<alkisg>
For greek schools that want to use thin clients, I'll tell them to stick with 18.04 for as long as they like, and then I'll probably implement a new version of ltsp without thin client support...
14:33
<Hyperbyte>
Oh maybe you know this
14:33
Since I migrated to 16.04 (from 14.04) people have been complaining about slowness...
14:34
Which I've tracked down to increased CPU usage on the clients.
14:34
<alkisg>
From which process?
14:34
<Hyperbyte>
So far I haven't dug into it properly, because I simply haven't had the time and the client hasn't prioritized the issue
14:34
But I figured maybe you know.
14:34
<alkisg>
Do you know the process name? Or should I guesS?
14:34
<Hyperbyte>
I believe it was X
14:35
<alkisg>
X usually means LDM_DIRECTX=False instead of True
14:35vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc)
14:35
<Hyperbyte>
First thing I checked, but the config seems okay
14:35
<alkisg>
Did it actually reach the clients?
14:36
<Hyperbyte>
How can I check if it's using compression or not? (I mean apart from checking the getltscfg -a stuff etc)
14:36
<alkisg>
Here's one client with 2 hdmi and some other stuff: https://www.gearbest.com/tv-box-mini-pc/pp_358225.html?wid=1654075
14:37* Hyperbyte boots a virtual PXE client as everyone has gone home
14:37
<alkisg>
ps aux will tell you if it's using ssh -X or not
14:37
And you could also check the actual forwarded ports...
14:37
<Hyperbyte>
That's not a bad one
14:38
!learn client-dualscreen as https://www.gearbest.com/tv-box-mini-pc/pp_358225.html?wid=1654075
14:38
<ltsp>
The operation succeeded.
14:39
<alkisg>
And this one with DP+HDMI: https://www.gearbest.com/mini-pc/pp_1672353.html?wid=1433363
14:39* alkisg would love an i7 mini client :D
14:40
<Hyperbyte>
That's a nice one, with 8 GB ram as well.
14:42
!learn client-dualscreen as https://www.gearbest.com/mini-pc/pp_1672353.html?wid=1433363
14:42
<ltsp>
The operation succeeded.
14:43
<alkisg>
And the cheaper one, https://www.gearbest.com/mini-pc/pp_009152598808.html?wid=1433363
14:44
<Hyperbyte>
It's using ssh -Y
14:45
So I guess LDM_DIRECTX is okay
14:45
I also can't see the CPU usage I was seeing earlier... oh well
14:46
I'll dig further another time.
14:46
It's time to replace the hardware anyways....
14:47
<alkisg>
Hyperbyte: ssh -Y means LDM_DIRECTX is not ok
14:47
It's compressed X
14:47
<Hyperbyte>
Isn't ssh -X compressed and ssh -Y without?
14:47
<alkisg>
No
14:47
Both are compressed
14:47
(if I remember well; it's been years since looking into thin clients... :D)
14:48
<Hyperbyte>
-C flag?
14:48
<alkisg>
Well actually it's the encryption part that's causing the ssh
14:48
the compression doesn't make much of a difference
14:49
The point is, on LDM_DIRECTX, neither -X nor -Y nor -C should be used
14:49
*when LDM_DIRECT=True
14:49
*that's causing the CPU usage
14:49
Meh I need to read what I'm writing before I press enter :D
14:51derick_ has left IRC (derick_!ab3cbcb5@gateway/web/freenode/ip.171.60.188.181, Ping timeout: 252 seconds)
14:54
<Hyperbyte>
Hmmm... weird that it's using -Y then
14:55
LDM_DIRECTX="True" is outputted by getltscfg -a
14:55
and ps aux ssh -Y -t -S /var/run/ldm_socket_1260_server server
14:56
<alkisg>
It might be a code glitch, and not actually use the -Y part of the connection even if it's there
14:56
<Hyperbyte>
But isn't -Y to enable X11Forwarding?
14:57
AFAIK, -X enables secure X11forwarding and -Y insecure X11forwarding
14:57
<alkisg>
Yes, i.e. the ltsp code might not be smart enough to disable it when LDM_DIRECTX=True, but smart enough not to use it :D
14:57
LDM_DIRECTX=True uses xauth + tcp forwarding, unrelated to ssh
14:57
<Hyperbyte>
Ah.
14:58
<alkisg>
*eh actually it's not called forwarding then, it's just normal networked xorg
14:58
<Hyperbyte>
ps aux: /usr/lib/xorg/Xorg :7 vt7 -auth /var/run/ldm-xauth-sPVeKQE6P/Xauthority -listen tcp -config /var/run/ltsp-xorg.conf -depth 16 -br
14:58
That looks alright then?
14:58
<alkisg>
Netstat will tell you
14:59
<Hyperbyte>
Xorg listening on 6007
14:59
<alkisg>
And does it have connections?
14:59
<Hyperbyte>
Yes, quite a few.
14:59
<alkisg>
And easier way: login to the client, and run echo $DISPLAY
15:00
If it's localhost:123, it's ssh, if it's a remote ip, it's directx
15:00
<Hyperbyte>
it's an IP.
15:01
:-)
15:01
<alkisg>
Great
15:02
<Hyperbyte>
I guess it's just general slowness. The server is 5 years old, the clients are 8 years old...
15:03
Have to replace stuff eventually
15:03
Going from 16.04 to 18.04 would be a nice occassion
15:03
<alkisg>
Which DE are you using?
15:07
<Hyperbyte>
MATE
15:14
<alkisg>
Nice, it's the one that gets the most testing :)
15:16
<Hyperbyte>
When I went from 14 to 16, I also switched from Gnome classic or fallback or whatever it's called nowadays to MATE.
15:18* alkisg will probably switch back to gnome in 20.04...

17:35
alkisg: unless you use a personal repository
17:35
<alkisg>
Got it
17:36
Hmm, if anyone asks for it, I might
17:36
<vagrantc>
if the bugfixes are feasible to backport to an old LTSP version, then you might be able to get it into stretch
17:36
selective, specific fixes, rather than new upstream versions
17:37
for new upstream versions with new features, upload to unstable, wait till it migrates to testing, and then upload to stretch-backports :)
17:37
<alkisg>
vagrantc: nah, I don't have the stomach for cherry picking, but it might be worth it to put it in stretch-backports
17:39

Great; I think I'll have finished the bulk of the work till then
17:41
I was pondering to create systemd units for ltsp, but then we'd also need to address SCREENxx handling, (i.e. rewrite start_screen_sessions) and I'm not sure it's worth it at this time

Note to myself: vbox thin clients (thin chroot) load vesa the first time (/dev/dri/card0 missing) and work with 16bpp, but modesetting the second time which doesn't work with 16bpp. Chrootless ltsp maybe delays a second and loads modesetting from the first time.

<vagrantc>
copy one of the the directories in /usr/share/ldm/themes/ to a new directory and set LDM_THEME=your-new-directory ... and edit it
19:52
e.g. change the images, adjust the colors in the gtkrc

hello everyone
20:10
I'm looking for inexpensive, readily available, small, quiet thin clients
20:10
it seems like everything I try is either : order from israel (fitpc) or just doesn't work (shuttle dx30)
20:10
and I'm wondering what people here use.
20:12
<alkisg>
!cheap-client
20:12
<ltsp>
cheap-client: https://www.gearbest.com/tv-box-c_11262/?attr=2081-1279
20:12
<alkisg>
...although schools here just order normal i3 desktop PCs, just without disk :D
20:13
<Leolo_2>
that's large and noisy though. a school probably has more room for that
20:13GodFather has left IRC (GodFather!~rcc@2603:3015:3507:1600:fc1f:1226:77d0:3d92, Ping timeout: 240 seconds)
20:13
<alkisg>
Yeah it depends on the environment. See the link I pasted above ^
20:14
<Leolo_2>
those will all work with ltsp? or do I just have to buy them and try?
20:14
<alkisg>
They should, but most haven't been tested
20:15
You might need to do a trick in some of them, to put the kernel locally, autoupdated with an lts.conf directive
20:15
...as uefi netbooting support isn't yet mature
20:15
<Leolo_2>
oh god, uefi
20:15
"kernel locally" as in uSD?
20:15
<alkisg>
All of them have local DOM
20:16
Not sd, internal storage
20:16
Like a small integrated ssd
20:16
Others 32gb, others 64... and you only need a few mb
20:17
<Leolo_2>
some form of mmc
20:17
<alkisg>
Right
20:17
In some cases, you should be able to just use legacy lan boot
20:17
But I haven't tested, so I wouldn't know which one would support that
20:19
<Leolo_2>
so I have to order each one, wait for it to ship from china, and hope it works...
20:19
<alkisg>
You can also google if anyone has ran linux on them
20:19
If they run linux, they surely can also run ltsp
20:20
<Leolo_2>
with my luck, I wouldn't be surprised if it didn't
20:20
but yes, that's a good point
20:21
<alkisg>
Those are intel based, x64, normal achitecture, nothing fancy like the berry/pi families
20:21
<Leolo_2>
right
20:21
but this DX30 I'm fighting with right now even claims "Ubuntu" support in the product spects but won't work with my current LTSP setup
20:21
<alkisg>
Does it boot from a usb stick?
20:22
And, what is the error message with ltsp?
20:22
<Leolo_2>
no error message. it's
20:22
just
20:22
very
20:22
very
20:22
slow
20:22
and it won't do graphics. I haven't looked into that part yet
20:22
<alkisg>
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Celeron+J3355+%40+2.00GHz&id=2960 => 1229 score
20:22
An i3 has 5000 score, but 1229 isn't that bad
20:23
So if it's very slow for you, maybe you have something misconfigured?
20:23
<Leolo_2>
as a test, I put my laptop's HDD in it, which has CentOS 6. and I'm getting an MCE error
20:23
<alkisg>
E.g. maybe you're using it as a thin client with LDM_DIRECTX=False, instead of as a fat client?
20:23
<Leolo_2>
no, even before it gets to X, it's slow

20:24
<alkisg>
Does it have gigabit networking?
20:24
http://global.shuttle.com/news/productsDetail?productId=2114 says "yes" to gigabit
20:24
So, it should boot in less than a minute, and it should be able to show full screen youtube
20:25
If it doesn't do that, it needs some better configuration or something
20:27
<Leolo_2>
right
20:27
but it doesn't
20:27
and the slow down is long before it gets to X
20:28
<alkisg>
What's the output of `dmesg` ?
20:32
<Leolo_2>
I can't even get that far
20:33
I mean there's a 3 minute delay between "dracut: Mounted root" and "dracut: Switching root"
20:33
<alkisg>
Dracut? Not ltsp?
20:33
<Leolo_2>
i'm using LTSP on CentOS
20:33
<alkisg>
Ah, I don't know if that boots anywhere
20:33
:D
20:34
It's been unmaintained for ages
20:34
<Leolo_2>
tell me about it
20:34
but I have it working. I have about 50 users on it. they are using FitPC2 computers
20:34
<alkisg>
You could give it a try with ubuntu if you want, maybe some more recent kernel will make a difference
20:34
!install
20:34
<ltsp>
install: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
20:35
<alkisg>
Not to change the distro; just to see if it's possible to make it work
20:35
<Leolo_2>
but those have to be ordered from Israel when we want to replace them, so we are looking for something with better availability
20:35
<alkisg>
Intel nucs then?
20:35
<Leolo_2>
also, something faster so the supervisors can use flash
20:35
the DX30 is a NUC
20:36
I thought NUC was an "idea" rather then a specific product
20:36
<alkisg>
I think it's a series of very specific products
20:37
See pics here (text in greek): https://www.skroutz.gr/c/329/barebones.html?keyphrase=mini+pc+intel+nuc
20:38
You could get i3 NUCs, they should offer very good performance, although at a higher price
20:38
<Leolo_2>
are you in greece?
20:38
<alkisg>
Yup
20:38* alkisg would love an i7 6770HQ one
20:39
<alkisg>
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-6770HQ+%40+2.60GHz&id=2759 => 9711 score, 8 times faster than the DX30 :D

<fiesh>
it's really fascinating... our server now is _5_ years old, but its two CPUs each have a score of 21488 and are thus basically still super top notch
20:46
20 years ago, anything older than 2 years was outdated garbage

<Leolo_2>
the transistors in CPUs can't get much smaller, or they become suceptible to quantum effects
20:51
we've been in a performance plateau for a while now
20:52
I doubt CPUs will get much faster. which is why we are seeing quad core in cell phones
20:53
alksig - 20 minutes later and the DX30 is still trying to finish udev initialization
21:09
<||cw>
it's mostly more cores, faster ram and IO buses, and less power use
21:09
which is fine, storage has been my bottleneck for some time.
21:10
<fiesh>
ram is still brutally slow, but I'm not sure that'll change
21:10
in fact, I think ram has become slower compared to CPU performance

booting took about 30 minutes
21:14
but I got to xdm, which is a first
21:27
<fiesh>
||cw: yeah, throughput is better, but memory latency is oftentimes the biggest bottleneck for common software, especially older one that wasn't written with data locality in mind since it wasn't a thing back then...

woooo ! think I'm getting some progress. If I boot with kernel-ml off the HDD, the problem seems to clear up
21:48
yep !
21:48
2 minutes to install kernel-lt is expected result
21:51
fyi, kernel-ml is the mainline kernel packaged for CentOS (currently 4.17.6) and kernel-lt is the long term kernel (currently 4.4.140)
