Does anyone have contact info for mistik1?
I have not seen mistik1.
...at least for 10 years or so :D
Last I heard, he was heading home to see his family in Jamaica.

alkisg: I've fixed the vnc problem with a workaround, the "-noxdamage" parameter, that slows the client refresh but at least does not crash. Maybe there are other parameter that can be fine tuned to regain some performance. xvnc4viewer made no difference
The broadcast stops expecially when you open the KDE menu (bottom left corner, the "start" Windows like button)
Wondering if you can detect Plasma desktop and adjust Epoptes behaviour on the fly, probably you don't want to add "-noxdamage" for everyone

markit: does it work with xvnc4viewer?
markit: try with a client: right click in epoptes, open terminal, root locally,
and: add-apt-repository ppa:ts.sch.gr; apt install xvnc4viewer; apt purge xtigervnc-viewer (or however else that one is called),
and then try broadcasting once more
I'm not in the lab anymore, I try to reproduce with my VM. Yesterday I installed xvnc4viewer (that purges xtigervnc-viewer), recreated the ltsp image / (AFAIR) and tested, same error
but let's see as you suggested to be sure
btw, if you are around for some time, I would love to try apache for http boot, since I gain 15seconds in boot speed
markit: really, ipxe tftp needs 15 seconds for you?
don't know if pxe boot is slow because I use "-rr" bound
It shouldn't need more than 5 seconds...
with -rr bound?
I'm using the default bond settings in ubuntu
btw, is it possible to setup dnsmasq to try http boot and "fallback" ipxe?
It needs less than 5 seconds with 2 gigabit nics
You can do that from inside ltsp.ipxe
I.e. you can tell dnsmasq to boot with tftp as usual, and load ltsp.ipxe which is small,
and then inside ltsp.ipxe, you can try http and fall back to tftp if it fails
In general I'm more available in the mornings when I"m at the office
E.g. around 10:00 greek time...
alkisg: I've limited skill, I'm more and more aware of it. So "you can try" means nothing for me, I've no idea where to begin :))
We've described that setup in github issues
You can start by reading the issues there
is a long discussion and I remember was not sure about the "final right config", but nevermind, I will ask you tomorrow morning after doing some test to save your time as much as I can
btw, is it possible have a "global config" in epoptes with PC groups? I want to create one group for each row of PC, and one "all pc", so teacher can Wakeonlan whatever wants
but I would love to have "global" in some way, so I don't have to copy it for each teacher and remember to do it if I create one new in the future
markit: btw, what about apache?
If you're looking for a single-port config, where's the difficulty in that?
I've no idea, I didn't realize that http boot is the same as fetching a html page, so did not thought about being in a different path, so I configured apache for port 8000
Well that should work too
everything seems to be ok (tcpdump) except the error Idontememberwhichone
Are you talking about your home setup, or about the lab setup?
and was not due to permission
Can I see now?
well, let me start ltsp VM server and a pair of clients, I was just updating documentation at the moment
I think the server would be enough
As long as http server works, http boot will also work...
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
I've the test server VM, but is not configured for http boot right now, I was looking for my notes and "ltsp-http-noot-site.conf" example I have somewhere, if not deleted by mistake
OK let's do it tomorrow morning...
markit: you really just need `apt install apache` and `ln -s /srv/tftp /var/www/html`
You don't need to edit any configuration files at all...
alkisg: yes, for a test, but I prefer have a separate site for boot, so I can leave the default site for html tests and page
symlinks are easier to manage than "sites", but whatever you like :)

alkisg, I've just installed LTSP under 20.04 and there is a missing step in the installation guide
|15:47||Guest24110 is now known as danboid|
After runnig `sudo ltsp image /`
alkisg, I get the error
Could not locate vmlinuz and initrd.img in /srv/ltsp/images/x86_64.img
and indeed LTSP fails to boot because of this
I followed every step on https://ltsp.org/docs/installation/

alkisg: apache2 and ln -s /srv/tftp/ltsp/ /var/www/html with the modification of /etc/dnsmasq.d/ltsp-dnsmasq.conf you did yesterday works, not I try with a specific site config file (don't like the ln stuff, sorry)
ok, done, created a ltsp-pxeboot-http.conf with only an "<VirtualHost *:80> Alias /tftp/ltsp /srv/tftp/ltsp/ </VirtualHost>", enabled a2ensite ltsp-pxeboot-http.conf and reloaded apache, works fine!

my bad, I'm not able to use apache without the ln you suggested, worked only because I forgot to remove the symbolic link :(
