| 07:10 | <alkisg> vagrantc: remember our last LDM_AUTOLOGIN chat? I have an idea there,
| |
| 07:10 | a new directive, MAP_HOSTNAME_TO_GUESTNAME="pc|guest"
| |
| 07:11 | ...so if the client is named pc01, then LDM_HOSTNAME would automatically get set to guest01
| |
| 07:11 | ...and my question is... while this is very convenient, I'm not sure it's easily explainable to others :D
| |
| 07:11 | <vagrantc> alkisg: i don't remember our last chat, but that sounds reasonable
| |
| 07:12 | <alkisg> Maybe the directive name isn't very appropriate... or the | syntax
| |
| 07:13 | My initial problem is that people set LDM_AUTOLOGIN and/or LDM_GUESTLOGIN to true, and that has issues with new clients that are not defined in lts.conf
| |
| 07:13 | * vagrantc might be to tired to really comment, though :) | |
| 07:13 | <alkisg> So I wanted to introduce LDM_AUTOLOGIN=auto, which you didn't like
| |
| 07:13 | Ah,let's leave it for another time then
| |
| 07:14 | <vagrantc> the default is to use the hostname of the client, no?
| |
| 07:14 | <alkisg> Yes
| |
| 07:14 | So for example the teacher sets up names like pc01, pc02 and LDM_USERNAME=guest01, guest02, and globally sets LDM_AUTOLOGIN, but then he changes a NIC and the client restarts Xorg all the time and he can't understand why
| |
| 07:15 | So I wanted a way to auto-disable autologin for "unknown" clients, that have the ltsp123 name
| |
| 07:18 | <Hyperbyte> Good morning. :-)
| |
| 07:19 | <alkisg> Hi Hyperbyte
| |
| 07:19 | <vagrantc> good morning, and good night! :)
| |
| 07:19 | * vagrantc waves | |
| 07:19 | <alkisg> bb
| |
| 07:19 | <vagrantc> alkisg: given those constraints, i think the mapping idea is pretty good
| |
| 07:20 | <alkisg> Cool
| |
| 07:20 | <vagrantc> alkisg: might fiddle with the names or syntax a bit, but overall seems fine
| |
| 07:20 | <alkisg> And we'd document that "if that new directive is set, it automatically sets or reset LDM_AUTOLOGIN as needed"
| |
| 07:20 | * vagrantc waves harder this time | |
| 07:20 | <alkisg> bb again! :)

| 07:20 | <Hyperbyte> I have the strangest problem with Chromium on Ubuntu LTSP Mate... somehow it stays 'always on top'... it's a bit hard to explain, but let's say I have LibreOffice, a Caja window and Chromium open
| |
| 07:21 | And I'm using the application switcher at the bottom panel to go to another application, it simply won't work until I minimize Chromium.
| |
| 07:21 | <alkisg> And you haven't actually checked "always on top" from its window menu, right? :)
| |
| 07:22 | <Hyperbyte> Well that is a good question. I shouldn't, as I have two companies with all kinds of users having this issue... but let me make sure.
| |
| 07:24 | Where is the Chromium window menu?
| |
| 07:25 | Ah found it
| |
| 07:25 | No, it's not checked.
| |
| 07:25 | <alkisg> Is that chromium-browser, or google chrome?
| |
| 07:25 | <Hyperbyte> Chromium browser.
| |
| 07:26 | Also it's not 100% consistent, but it happens frequently enough so I can reproduce it easily. I think that after I've minimized it, I can switch to another application, but as soon as I switch to Chromium again it won't go anymore
| |
| 07:27 | <alkisg> Ah it also has an option to enable/disable system window borders
| |
| 07:27 | Which I guess means "marco" window manager
| |
| 07:27 | <Hyperbyte> I've seen that option, but doesn't change a thing.
| |
| 07:27 | What kind of frustrates me....
| |
| 07:28 | I've had this issue in Ubuntu 14 although less frequently, and I also have it in Ubuntu 16, at two different companies.
| |
| 07:28 | And yet when I search online, all I find is unrelated garbage.
| |
| 07:29 | To me, it seems like a common issue, but apparently it isn't.
| |
| 07:33 | When it first occured I figured the folks at Chromium would remedy it in some update... but that didn't happen and according to Google, I'm the only one experiencing this on all users and all clients across two companies with different installations. :-D
| |
| 07:34 | So I kinda think it might be LTSP related. As Ubuntu 16 Mate with Chromium seems common enough.
| |
| 07:34 | Ubuntu 16 Mate LTSP with Chromium is less common I guess.
| |
| 07:35 | Oh this is with thin clients btw, although I can also reproduce the issue on an x2Go session strangely enough.
| |
| 07:38 | <alkisg> Ah, I haven't tested thin clients, although I would guess that if you enable the system window border, it would work fine
| |
| 07:38 | <Hyperbyte> It is enabled by default
| |
| 07:38 | And in this case it is.
| |
| 07:38 | <alkisg> Enabled by default? Not for me here...
| |
| 07:39 | I have the chromium-browser blue bar, not the mate black bar
| |
| 07:40 | <Hyperbyte> Hmmm... I do, but maybe that's my settings then
| |
| 07:40 | But doesn't change a thing.
| |
| 07:41 | Would you like to take a look? ;-)
| |
| 07:42 | <alkisg> Sorry installing ltsp to schools currently!
| |
| 07:46 | <Hyperbyte> That's ok, if you do have time later let me know. :-)
| |
| 08:01 | Statler has joined IRC (Statler!~Georg@p579FE97B.dip0.t-ipconnect.de) | |
| 08:06 | * alkisg isn't very fond of troubleshooting thin client issues :D | |
| 08:08 | <Hyperbyte> Why not? :-)
| |
| 08:08 | (will it help if you're troubleshooting an x2go session? ;-))
| |
| 08:12 | <alkisg> Haha
| |
| 08:13 | Thin client users are the ones that don't have money to pay for services :D
| |
| 08:19 | <Hyperbyte> Actually only reason we're using thin clients is because of efficiency... I don't have to maintain or clean workstations, just the server... I bought pretty powerful thin clients, but so that they don't have active cooling so there's no noise from computer fans in the office...
| |
| 08:23 | Of course client cost is a nice factor, but we negated that with the costs of the server.
| |
| 08:45 | <alkisg> " I don't have to maintain or clean workstations, just the server.." => isn't that the same with ltsp fat clients?
| |
| 08:46 | LTSP fat clients have the benefit that things don't run remotely, where developers don't care if things are broken
| |
| 08:47 | E.g. if you report that issue you're having to chromium-browser, noone will care, while if it happened in ltsp fat clients, it would also happen in standalone clients, i.e. in all users, so they'd care
| |
| 09:44 | <Hyperbyte> alkisg, maintain/clean, I meant physically.
| |
| 09:44 | <alkisg> fat clients aren't physically fatter than thins :)

| 14:57 | <TFC> i have multiple architecture fat clients i want to use LTSP to manage users and program updates but im unsure on how to do this especially regarding booting to a static IP that the server is on (DHCP is not an option)
| |
| 15:02 | <alkisg> TFC: let's answer that one by one
| |
| 15:03 | mikkel has left IRC (mikkel!~mikkel@mail.dlvs.dk, Quit: Leaving) | |
| 15:03 | <alkisg> What kind of architectures?
| |
| 15:03 | What do you mean "booting to a static ip dhcp is not an option"? Do you know about proxydhcp?
| |

| 15:34 | <TFC> ARM and AMD64
| |
| 15:35 | and i want the fat clients to look at a specific ip to boot
| |
| 15:35 | <alkisg> !raspberrypi | echo TFC:
| |
| 15:35 | <ltsp> TFC: 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/
| |
| 15:35 | <alkisg> #1 there describes i386 and raspberry, your case is similar
| |
| 15:36 | All DHCP clients look at a specific IP
| |
| 15:36 | The one of the dhcp or proxydhcp server
| |
| 15:36 | <TFC> yep
| |
| 15:36 | <alkisg> If you have a dhcp server, you can use a proxydhcp one
| |
| 15:36 | If you don't want a proxydhcp server, then you need some form of locale media
| |
| 15:37 | zibis has left IRC (zibis!~zibi@mail.linseco.pl, Quit: zibis) | |

| |
| 15:37 | zibis has joined IRC (zibis!~zibi@mail.linseco.pl) | |
| 15:37 | <TFC> they all have HDD's
| |
| 15:37 | <alkisg> Yes but I don't think you know what proxydhcp is
| |
| 15:37 | So you want something that is not suitable for you
| |
| 15:38 | <TFC> yeah i only know basics of networking
| |
| 15:38 | <alkisg> OK then start with this;
| |
| 15:38 | !ltsp-manager
| |
| 15:38 | <ltsp> ltsp-manager: LTSP Manager is a GUI tool that makes LTSP maintenance easy. It's the recommended way to install LTSP in common setups. More info: http://wiki.ltsp.org/wiki/Ltsp-manager
| |
| 15:38 | <alkisg> When you are finished booting the amd64 clients, then follow the previous link with the raspberry pi
| |
| 15:39 | <TFC> okay thanks
| |
| 15:39 | <alkisg> Do you have a dhcp server or router in your network?
| |
| 15:39 | <TFC> yes
| |
| 15:39 | <alkisg> Even a microsoft dhcp server, untouchable?
| |
| 15:39 | Then yes proxydhcp is fine
| |
| 15:39 | <TFC> pfsense router
| |
| 15:39 | <alkisg> Go for that one
| |
| 15:39 | Cool
| |
| 15:39 | Follow those 2 pages, in turn
| |
| 15:39 | Fir ltsp manager, then raspberry pi page
| |
| 15:39 | *first
| |
| 15:40 | <TFC> okay ill try that

| 17:54 | <bitingmidge> LDM_AUTOLOGIN=True has been working for me for years but has stopped sometime in the last couple of weeks (clients don't reboot all that often so I didn't notice). Both server and client running Ubuntu 16.04 and have unattended-upgrades running so maybe a package update broke it? I can see the lts.conf file being requested in the logs but client is now being dropped into an Ubuntu login screen instead of auto login. Any ideas?
| |
| 17:55 | <alkisg> bitingmidge: replace LDM_AUTOLOGIN with LDM_GUESTLOGIN
| |
| 17:55 | Do you see the LDM login screen and the guest login button?
| |
| 17:55 | Wait, what ubuntu login screen?
| |
| 17:56 | LDM or LightDM?
| |
| 17:56 | Or text?
| |
| 17:58 | <bitingmidge> It must be LightDM. It's the Ubuntu one.
| |
| 17:59 | <alkisg> Does it have a white background?
| |
| 17:59 | Can you login in that DM?
| |
| 18:00 | <bitingmidge> Yes, I can log in with the user I want to auto login as and it logs in correctly.
| |
| 18:00 | <alkisg> (08:59:39 μμ) alkisg: Does it have a white background?

| 18:01 | <bitingmidge> No, it's an Ubuntu graphic.
| |
| 18:02 | <alkisg> if you login to the client, and open a terminal, what's the prompt?
| |
| 18:02 | e.g. user@ltsp123
| |
