When I opened the Bultin NVC Server, the setting was on. I changed the setting to OFF...no change in which monitor was being sent in demo mode.

Then, I turned the setting back on...and the Demo went to showing all three of my Master Monitors, quite small, to the user.

So, I turned that setting back off...and now back to sending the wrong monitor.

Anything else I can try? EDIT! I went back to the Display Settings, and played around with the "Make this my main display" again, and this time it switched where the demo is being sent!!! WHEW!!!

Thanks for the reply!!

4.2.1 seems to be working thanks

Which distribution are you using?

Issue has been fixed in 4.2.1 🙂

Hello @tobydox
I updated to stretch on a test machine. It worked fine, thank you.

Solved. Must be authenticated with key and not with logon

Hi @tobydox
Still loving Veyon BTW!

Thanks for letting us know. Can't wait for 4.2.1 now 👍

@alessio Veyon 4.2.0 packages for Ubuntu Bionic, Cosmic and Disco are now available in the PPA.

@Thyncho88
we changed the way the driver is being installed so this should not be an issue any longer and we did not receive any complaints for the last months.

@tobydox
Thanks for reply.

Where can i find the JSON file?

Hi @ryankim
may be there's an issue with your DNS setup? Are you fetching computer names from LDAP? If so, does it return proper hostnames which can be resolved to IP addresses?

Perfect! Thank you for your feedback!

Hi,
I can bring a little feedback on the wake on lan,
It is necessary to check in the bios of the computer the activation of the wake on lan. This setting is different depending on the motherboard. This setting is usually found in the power management menu and is often disabled by default for security reasons. This parameter is sometimes hidden under the name of power on by pci-e card.
In the case where your network is segmented into VLANs and the master station is connected to a different VLAN of the students, check that your switch infrastructure propagates the magic packet between the two or more VLANs. A switch configuration will be necessary. In my case, i forward the port udp 9 to the student VLAN. In a first time adjusts and test your configuration in the same VLAN.
Of course you also have to check the parameters of the network card under window or linux. Verify that your linux configuration is reboot persistent.
Regards.

Hi @gioni
this is currently not possible but you can simply remove /usr/bin/veyon-master after installation.

Hi,
I was trying with the key file authentication, but student's computer doesn't show.
Should I use the logon authentication?
When installing Veyon in lynux, the box to indicate the program is being installed in a student's or a teacher's computer (master) doesn't show. I'm not familiar with lynux and I don't know if it's ok.
Thanks

Hi @Thomas-Suhalim
unfortunately this is currently not supported by Veyon. We might add this in Veyon 5 in 2020 but can't make any promises yet.
Best regards

Hi,

It works better but sometimes I do not have access it takes me time to start by control or the opposite "to see at a distance" and it works.
Sometimes I need to restart the software and allow the screen time to appear.

Where does the problem comes from ?
 
Of course, It's better than without address MAC.

Thank you 😊

Hi Tobias:

Thanks for your answer. I use 12 computers and the bandwidth not exceed 5Mb in the worst case, all processors in the master runs below 1%. Changing the screen update not affect the behavior. Unfortunately I need to downgrade to iTalc, veyon it's unusable for me.
Edit: I install iTalc again and works ok. If I change parameters can't reply de Veyon behavior but if I choose iTalk demo internal server everything work slowest. Maybe this can help you to detect the problem.
