That's indeed a strange behavior. Are you using the builtin network object directory, i.e. added the student computers manually in Veyon Configurator? If so, did you enter IP addresses or host names in the host address column?

Thank you for sharing your findings!

@makerspacelab I have good news for you: this feature will be implemented in 4.6.1. If you already want to test, you can download and install the current test build at https://github.com/veyon/veyon/releases/download/v4.6.0/veyon-4.6.0.32-win64-setup.exe – besides messages being selectable/copyable student-side, it's now also possible to copy rich content, i.e. formatted text including hyperlinkers.

@rnetuband How would you do this? Would we be able to fix this within our classroom or through the district?
I have the same concern as stated above.

Thank you for sharing your solution! The troubles you had might be related to https://github.com/veyon/veyon/issues/761 so until 4.6.1 is released you could try again with computer groups and make sure the nested groups option is not enabled.

Hello, thanks for at least answering, but my question is actually very simple and everyone who uses Veyon had to do the same thing I have to do. Namely establishing a connection to another computer, in this case a network. My question is how can I create a network with several computers so that Veyon can be installed, set up and used. Unfortunately, I am not very familiar with networks. I can do the rest by myself.

@qwyrj Hi, I found a way with this setting, it works! just define the enviroment variable on your user to VEYON_SESSION_ID to a number like 2, and on your server configuration window (Local and Network...) set the IP of your computer adding ":1110x" where "x" is the number of the session defined to your user! works like a charm!

@sergey Hello from Brazil, I'm trying to setup right now, it sems to start to respond, when i figure out, i'm coming back to post it if you still need some help!

@tobydox I have the same problem with LinuxMint (which is based on Ubuntu 20.4). The service veyon seems to be running properly, but telnet localhost 11100 says Unable to connect to remote host: Cannot assign requested address, and the message on the Master "veyon service unreachable or not running".

The same problem happened with version 4.3.1 which is the one packaged on ubuntu-20.04, and the same happens with the latest release downloaded from veyon.io.

@tobydox thanks

You should check the permissions of the key with:

$ ls -al /etc/veyon/keys/private/teacher/key
