Hi @HetElsner1
do the passwords match on both computers? Have you read https://docs.veyon.io/en/latest/admin/troubleshooting.html#computers-can-t-be-accessed already?

Hi @jhostetter

thanks for your detailled information and proposals. To be honest the key file authentication mechanism is not made for such scenarios. Instead it provides basic facilities to manage access for different user groups, e.g. teachers, administrators and support staff.

I suggest to use access control rules instead. There are numerous possibilities thanks to many different rule conditions - see https://docs.veyon.io/en/latest/admin/access-control-rules.html#conditions for details. There's a condition "Accessing computer and local computer are at the same location" which should fulfill your need exactly. To make it function properly you'll have to either maintain the builtin directory (locations and computers) on student computers as well (simply by deploying the same configuration to student and master computer) or preferably make Veyon use these information from your LDAP/AD server. Don't hesitate to ask further questions if you're stuck with access control rules.

Best regards
Tobias

Hi @cynical
FYI: this issue will be fixed in the upcoming 4.2.5 release.

Hi @thodge
this could be a bug in the builtin directory plugin. I suggest to use the command line interface for managing or clearing the orphaned objects - see https://docs.veyon.io/en/latest/admin/cli.html#network-object-directory for details. You could help debugging this issue by posting the output of

veyon-cli networkobjects dump

Hi @RoggerJones
Even though we do not want Veyon to be used for spying you could probably use for such purposes. Please read the documentation for information on installation and configuration.

Hi @OSSJack19

there's currently no solution except for using the window demo. We'll try to improve this behaviour in Veyon 5.0 (coming in 2020). To help us please submit a bug report at https://github.com/veyon/veyon/issues/

Hi @cpbools
please submit a bug report at https://github.com/veyon/veyon/issues so we can track and fix this issue.

Hi,
this is the right way.
The top bar is set to manage the whole group of computers. Then if you want to control one of them or see one screen, you'll have to put the ip adress... or use the right clic on the desired computer. So you can have what you need.

Hi,
I solved my problem although I do not understand why it didn't work.
I changed the condition :

General :

inversion of all conditions : checked

Condition :
checked accessing computer is in C12 rem: C12 is the place of clients

accessing computer is local host : checked unchecked

Action :

Ask permission to the connected user : checked

Thank you.

@tobydox Sorry for not replying for so long. I had a vacation.

So, I installed Veyon 4.2.4 on my school PC. And is still doesn't work for me.

I tried both authentication methods "Logon authentication" and "Key file authentication". Also I enabled Multi session mode in Veyon Configurator. All my zero clients have static ip address. Also i enabled sharing files on windows.

My clients in Veyon Master are red, so i presume Veyon see them, but couldn't connect. I tried adding my computer's ip address to Location & Computers and it's working in Veyon Master!

Maybe I'm missing something? Here's link to veyon logs and screenshots of Configurator.

Hi,
You probably have another VNC application already running like italk, or ultravnc.

Hello,
I would first uninstall properly the previous version with full admin rights before trying to setup the new one 4.2.4. (and especially if version 32bits and 64bits have been mixed in the past)
I did experienced such difficulties with old versions. Solved by uninstalling with revo, and cleaning all reg keys...

Hello,
I've seen also reactivity problems (mouse blocked) on the master when a big amount (100) computers are checked (which should not be used to my point of view).
Thank you.

Hello,
Are you using wifi or RJ45, or a mix of both?
Which antivirus do you have on the clients and master?
( I do experience the same issue, only in wifi) and also in 4.2.4

thank you

Which version of Veyon are you running?

Have you enabled the option on the clients you want to view?

Hi @Dembe
thanks for testing Veyon and investigating this issue! Can you please try again with the latest 4.2.4 release?

There's currently no option for this. We plan to improve the bandwidth utilization of the demo mode in Veyon 5 in 2020.
