| 17:19 | <alkisg> vagrantc: heya; ltsp was unblocked in both bullseye and focal; I uploaded a new version; in a week or so, after it receives a bit of testing, if you want you can upload it to testing...
| |
| 17:20 | bengoa has joined IRC (bengoa!~alberto@194.50.55.200) | |
| 17:27 | <alkisg> And I think I managed to do a signed tagging... :D
| |
| 17:31 | <vagrantc> i saw, cool!
| |
| 17:31 | oooh!
| |
| 17:32 | alkisg: you might need to "git push --tags"
| |
| 17:32 | eu^167214223 has joined IRC (eu^167214223!a7152a17@167.21.42.23) | |
| 17:32 | <alkisg> Ah right
| |
| 17:33 | * [new tag] v19.12 -> v19.12
| |
| 17:33 | ! [rejected] v19.11 -> v19.11 (already exists)
| |
| 17:33 | I guess that's good enough :D
| |
| 17:33 | <vagrantc> which for some projects, i configured it to always push tags present in the current branch ... though i try to do that on a per-project basis
| |
| 17:33 | <alkisg> I think I also tagged v19.11 and never pushed it, and you did instead
| |
| 17:33 | <vagrantc> alkisg: looks like i tagged v19.11
| |
| 17:33 | right
| |
| 17:43 | Patw has left IRC (Patw!a7152a1a@167.21.42.26, Remote host closed the connection) | |
| 17:44 | * alkisg wonders if the binary packages like ltsp-client-core etc will be automatically removed from unstable or if another ftp master ping will be needed | |
| 17:45 | <alkisg> https://packages.debian.org/ltsp => testing is OK, but unstable isn't
| |
| 17:45 | Hmm strange the server packages were removed, but not the client ones
| |
| 17:46 | Also maybe ltspfs should get removed too.. and maybe ldm as well
| |
| 17:47 | <vagrantc> yeah, i'll switch the orphan bugs into a removal bug at some point end-of-year-ish
| |
| 17:49 | Patw has joined IRC (Patw!a7152a1a@167.21.42.26) | |
| 17:50 | <Patw> Hello. How can I troubleshoot LTSP19 on Ubuntu with clients that do not have internet access? I can ping the client from the server and the server from the client. This is a 2-nic setup
| |
| 17:57 | eu^167214223 has left IRC (eu^167214223!a7152a17@167.21.42.23, Ping timeout: 260 seconds) | |
| 18:18 | <Patw> Nevermind. For those looking at archives later, I created the lts.conf, set nat=1, restarted the ltsp service on the server.

| 18:43 | <alkisg_android> Patw, did you set NAT=1 in ltsp.conf and rebooted the server?
| |
| 18:43 | <Patw> Yes
| |
| 18:47 | <alkisg_android> Can you pastebin your ltsp.conf?
| |
| 18:48 | Btw can clients ping 8.8.8.8?

| 19:19 | <alkisg> $ journalctl -u ltsp | grep forwarding
| |
| 19:19 | Νοε 13 02:11:36 alkis ltsp[1481]: Enabled IP forwarding/masquerading for 192.168.67.0/24
| |
| 19:19 | This is supposed to show that ^ if NAT is enabled
| |
| 19:20 | vagrantc: ltsp-client-core isn't related to the orphaning though, right?
| |
| 19:21 | <vagrantc> alkisg: no, those might be decrufted at some point
| |
| 19:21 | * alkisg asks in #debian-release... | |
| 19:22 | <vagrantc> alkisg: are you worried about them hanging around
| |
| 19:23 | <alkisg> vagrantc: I'm just trying to do "our" part of the related tasks... e.g. in #ubuntu-devel they told me that if I hadn't pinged them, ltsp would never migrate from proposed to focal
| |
| 19:30 | Ah it's debports, not main unstable

| 19:57 | <paradoxewan> Hi there
| |
| 19:57 | <alkisg> Hello
| |
| 19:57 | <paradoxewan> nice to meet you all :)
| |
| 19:58 | found you through the epoptes application
| |
| 19:58 | Can anyone tell me how to change the configuration for the VNC client inside epoptes to use the second screen on a client
| |
| 19:58 | <alkisg> How would you do it from the command line?
| |
| 19:59 | <paradoxewan> id assume changing 0 to 1
| |
| 19:59 | <alkisg> Is it a different display, or just a different monitor?
| |
| 19:59 | Is it just a dual screen pc?
| |
| 19:59 | <paradoxewan> secondary output on raspberry pi
| |
| 19:59 | <alkisg> With a single user?
| |
| 19:59 | OK
| |
| 20:00 | And that's for the epoptes "teacher" broadcasting function?
| |
| 20:00 | <paradoxewan> yes single user, i have a few deployed for digital signage and this might be a great way to monitor them]
| |
| 20:00 | <alkisg> Then that's for the teacher monitoring function?
| |
| 20:00 | <paradoxewan> yes thats correct
| |
| 20:00 | <alkisg> Can I see?
| |
| 20:00 | !vnc-edide
| |
| 20:00 | <ltspbot> 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
| |
| 20:04 | <alkisg> paradoxewan: so YOU have a dual screen and you want VNC to open in YOUR second monitor?
| |
| 20:04 | <paradoxewan> no
| |
| 20:04 | kilmarnock screen should be showing the content its playing
| |
| 20:04 | its live on a remote site
| |
| 20:04 | <alkisg> There's no root connection there, that client has issues
| |
| 20:06 | Also, xrandr doesn't list 2 monitors for that client
| |
| 20:06 | <paradoxewan> ok perhaps its on a single monitor setup at the moment im not on site
| |
| 20:06 | but it is showing content
| |
| 20:07 | <alkisg> The only dual screen I see is your own
| |
| 20:07 | Both your clients seem single screen
| |
| 20:07 | <paradoxewan> ok, so lets assume the client is a single screen, is there a reason i can see content on one and not the other, they are both the same operating system
| |
| 20:07 | <alkisg> Yes
| |
| 20:07 | ps aux|grep epoptes-client
| |
| 20:07 | This should show TWO processes
| |
| 20:07 | One for the user, one for root
| |
| 20:08 | In the second client, there's no root epoptes-client process
| |
| 20:08 | <paradoxewan> ok, waht would cause that
| |
| 20:08 | <alkisg> The best way forward is to update your epoptes-client to 1.x from the PPA
| |
| 20:09 | <paradoxewan> ok, looks like i might need to do a bit more reading on this then.
| |
| 20:09 | <alkisg> I.e. just install a newer epoptes-client
| |
| 20:09 | You have a very old one
| |
| 20:09 | <paradoxewan> It could be the perfect tool for me monitoring these sites remote
| |
| 20:11 | thank you for your time, thats really helped. Im fairly new to the linux world
| |
| 20:13 | <alkisg> You're welcome
| |
| 20:16 | <paradoxewan> is there a simple upgrade path on rasp-pi?
| |
| 20:27 | <alkisg> cd /tmp; wget https://code.launchpad.net/~epoptes/+archive/ubuntu/ppa/+files/epoptes_1.0.1-2+t201911250838~ubuntu16.04.1_all.deb; apt install ./epoptes*.deb
| |
| 20:32 | Sorry that one is for epoptes
| |
| 20:32 | wget https://code.launchpad.net/~epoptes/+archive/ubuntu/ppa/+files/epoptes-client_1.0.1-2+t201911250838~ubuntu16.04.1_all.deb
| |
| 20:32 | This is the correct one
| |
| 20:33 | <paradoxewan> thats amazing, ive learned at least three different things from that one command lol.
| |
| 20:33 | <alkisg> You're a fast learner then :)

| 20:40 | <paradoxewan> ok, so installed the update, and rebooted the client and i seem to have lost it
| |
| 20:41 | the second client (not updated yet) is still showing black screen
| |
| 20:46 | paradoxewan has left IRC (paradoxewan!516f7236@cpc127050-irvi3-2-0-cust53.14-1.cable.virginm.net, Remote host closed the connection) | |

| 20:51 | <paradoxewan> ok, had to reboot client. Both are now showing in Epoptes but with black screens
| |
| 20:56 | <alkisg> paradoxewan: vnc to me again

| 21:01 | <paradoxewan> ive got it working :) at least on the client i updated
| |
| 21:03 | <alkisg> Nice
| |
| 21:03 | <paradoxewan> this is actually brilliant. The units im looking at are 20 miles and 50 miles away from me. I have the networked via zerotier, so its all on its own little self contained vpn and i now have a screen where i can monitor these and interact with them remote. Thank you for your time. We i get a chance ill look at the source for this and see if there is
| |
| 21:03 | anything we can contribute in the future. Its a brilliant tool
| |
| 21:05 | The only think i have to figure out now, is one of the units is a large outside LED screen. The way the content renders it is only using the top left corner of the desktop display (so imagine a little box in the top left of full desktop)
| |
| 21:06 | i dont know if its possible to get vnc to only send back a portion of the screen, so that this displays "full" on epoptes
| |
| 21:07 | <alkisg> The realvnc vnc viewer supports scaling
| |
| 21:07 | You'll need to install that one in your epoptes pc
| |
| 21:08 | I have some tasks for potential contributors in https://epoptes.org/documentation/gsoc/
| |
| 21:11 | <paradoxewan> ok, will have a look. I have limited experience in webrtc, but im from a osx background and learning linux as fast as i can at the moment
| |
| 21:16 | <alkisg> Bed calls me; 'night all :)
| |
| 21:16 | <paradoxewan> Thank you again. Speal soon
