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.

@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

"install the official all-in-one package which can be downloaded from our website" Is it possible to have the adress of a repository that could be added in /etc/apt/source.list instead of download the package via the website ? (For debian)

@Astring can you elaborate a bit more on what you're trying to achieve? Did you export a configuration file previously and want to import it on another computer?

@mb-one Our PPA now contains the latest 4.6.0 release which should fix the mentioned issues.

Simply by adding the IP addresses or hostnames of the computers in the other network. This requires proper routing to be set up such that the computer running Veyon Master can connect to each of the other computers by distinct IP addresses.

@tobydox Thanks! With that version everything works fine.

Veyon is free and Open Source so you don't have to buy a license. In case you want to use some of the commercial add-ons (such as Internet Access Control or Network Discovery) for extra functionalities, you can buy licenses for these add-ons separately.

@Deh-Castro Veyon uses system and/or domain users so simply log in with your teacher account (which in case of local users should exist on student computers as well). If you don't have domain users, consider using the key file authentication method. See https://docs.veyon.io/en/latest/admin/configuration.html#authentication-methods for more information and a comparison of both methods.

@tbuller Probably the download somehow failed? I just downloaded the file and it has a size of around 1.8 MB. Alternatively use our PPA so you benefit from automatic updates and better dependency resolving upon installation.

@tobydox Thank you for the explanation. I use "Show notification on remote connection".
