Hi.

When sending a command to open a website to a PC that is logged in with a user who does not have administrator permissions, firefox and google chrome browsers do not open. Only internet explorer works this function.
In firefox it presents the error that the user profile could not be opened, it was not found.

Google chrome does not even open.

I appreciate it if you can help me.

I always have the problem with the access keys creation.
I send you the attached file with the error. I put all the permissions on /etc/veyon/keys/private/teacher but it is always unable to write the key in the folder

Thanks you very much for your help

http://veyon.io/wiki/ points to a dead page.

After running the veyon configurator on windows 10 i copied the Program data/veyons/keys/public/teacher/key in /etc/veyon/keys/public/teacher
Then i gave the privileges with sudo chmod -R 0755 /etc/veyon/keys/public/teacher

Veyon-serice is started on the client and i specified ip adress and mac adress in computer /room on veyon-configurator windows 10
But when running veyon master on windows 10 nothing in the monitor screen as you can check on the screen capture below

This can cause accesses to uninitialized AuthenticationCredentials instance in VeyonCore::authenticationCredentials().

Hello

I have a new error now on the linuxmint veyon client screen when using the "logout user" option on Veyon master. The window error is :
"recue error during disconnection - Could not get owner of name 'org.xfce.SessionManager' : no such name.
In the same time i also have the error in the terminal linuxmint client where veyon service is running
"cannot find '.logout' in object /KSMServer at org.kde.ksmserver

Hope you will find the solution. Thanks you again for your work!

Hello for a new issue

Option behaviour "logout user" doesn"t work with a Veyon master on Windows 10 and a Linuxmint client.
When i select "logout user" in veyon-master i can see this message in the Linuxmint terminal where veyon-service is running

Cannot find '.logout' in object /KSMServer at org.kde.ksmserver

And nothing happens there is no logout for the session user. If this option could work then the user session should be closed and going back to the logon screen.

Veyon-ctl config import/export is useful to restore computer list and rooms.

But how can I save and restore displayed room/computer in veyon master for all users on Windows ?

This would be a useful tool for my users if the room is already selected as they run veyon master. (The teacher computer is used to control the same room by all my user)

Thanks.

Hello again,

After running the Veyon-master as root; i can see my room with computer listed in the room/computer area but nothing appears in the right window. No computer screen when i select the computer. Look the screen capture below

Hi everybody !

I discovered Veyon yesterday afternoon as I wanted to see if Italc had been updated lately.

I've decided to post here to ask for help. I hope it is the right place :)

To be honest, I was quite puzzled when I tried to create a classroom and to see it in Veyon Master. I always had to click on the computer rooms button. I think I've found how to make the classroom appear when we launch the Master : when we create a classroom, we must add the computer used by the teacher. Then, the classroom will appear when we start Veyon Master. I think it is the correct way to do ?

Now, I face two serious problems :

1. I can't move the screens in Veyon Master and I can't put the computers at the right place, but it was possible with Italc. For instance, I can't create 3 rows, then put PC1 next to PC2 and in front of PC3. Therefore, as all the PCs are automatically put one after the other, it is not convenient at all and I think that it will be a problem for my colleagues.

2. when the classroom is displayed in the master, I only see the name of the computer, not the name of the person who is logged. In Italc, there was an option to display the student's name

Thanks for your help !

Hello.

In testing with Veyon, I realized that the software does not perform on-screen monitoring of Windows users.

In iTALC this function worked, where it could perform the remote access by iTALC itself and logged in to the PCs.

Would it be possible to create a closed applications function to close all programs on the monitored stations?

Thanks if you can help.

Hello again

I installed the latest version of Veyon.
Always the same problem when running veyon master on Linuxmint after checking "automatically adjust computer thumbnail size" in veyon configurator >>> Veyon-master close 2 seconds after running and there is just the master icon notification on the taskbar.
Here is the veyon master log :

Any help would be really appreciated. I really would want to try this new version for some school.
Thanks you very much

Are you going to provide a Windows Installer package (MSI) for Veyon or may I assist you in creating it?

Hi,

Veyon 3.99.5 for Windows (tested with 32 and 64bits version, on Windows 7 and Windows 10 Pro) :
I had a problem with italc 3, same issue with Veyon 3.99.5 => authentification fail if the password contains special characters like é,à,ç,ù,è, ... (french keyboard).
Tested with local accounts and ActiveDirectory accounts.

Please can you fix it ? (i'm ready to beta-test if needed)
(Logs attached (one successful authentification, then i add character 'é' to my password and authentification failure)

Very good job btw
Thx

Hello again

I have a problem when adding rooms and computer in Veyon-configurator.
When i save parameters in UserConfig.json after adding room and computers there is nothing then in the following line of the .json file
},
"LocalData": {
"NetworkObjects": {
"JsonStoreArray": [
]
}
And when i run veyon-master same thing there are no room and computers.

I also have a problem when creating keypaiir in /etc/veyon/keys/private/teacher and /etc/veyon/keys/public/teacher. i'm login as root but it said that i haven't the privileges for these files.
I changed privileges with chmod 777 but same problem again.

Thanks you very much for your help again.

In the main window, on the left (Computer Rooms > Room/Computer) if I expand a Room under the 'Computer rooms' the computers are sorted numerically like:

Room 01:

• PC01
• PC02
• PC03
  etc.

But when I select the room (and by doing that all computers in that room are selected) or some Computers in that room, the screen on the right (does it have a name?) are scrambled / not sorted, so I see e.g.:

PC03 - PC07 - PC01
PC02 - PC04 - PC06
PC08 - PC05
etc.

Is there a setting in the registry or Veyon configurator so this can be solved and I can see the computers sorted by number?

This is more of a suggestion than an issue, i've been trialing Veyon over our current remote support software, and it does everything we currently want to do, and quicker, except for one thing. It would be nice to have the ability to remotely login a batch of workstations with a provided credential.

Other than that, great piece of software.

Hi There,

New to this product, I have configured it on two pc's and PC1 will be the controlling PC. So I have on PC1 under veyon configurator - local data - added the details of pc2. But on opening the Veyon master and clicking on computer room, there no pc's shown basically it is empty.

Please can you help.

Regards
Abhi

When right-clicking on a computer and locking it. It's impossible to unlock it afterwards. The context-menu doens't state unlock.

Group locking and unlocking does work.

I'm using veyon for a class with 40 - 50 students. there are 40 Acer Iconia 10'' tabs. I'm using a Unifi AP AC Lite Access point to connect all of them. Im also using a gigabit switch. Veyon master is in a HP i-5 laptop with a 4 GB RAM. OS is windows 10 pro.
When i use only 10 -12 system is working properly. But when i I try to connect mor (20 -30) there is a huge delay in the demo(10 - 15 seconds). Also the veyon master frequently closes after exceptions. Is this happening because of the limit of concurrent desktop connections in windows 10?. Will it be sorted if i use a windows server 2012? or is there anything that u can advice me.

Hello all,
I'm trying to install veyon for a school (thanks for your work) but under windows 10 I always get the following error :
An error occured while importing the public access key. You probably are not permitted to read the source key or to write the destination file.

I tried to start Veyon configuration in admin mode, changed the destination folder, deactivated the UAC but still can't import the key. If someone has an idea :)
Per advance, thanks to all for your help :)

I recently compiled Veyon for GNU/Linux (Mint 18.1 -Ubuntu 16.04-).

I also generated a .deb package and installed it. But veyon-configurator show the next message:

2017-05-16T23:45:05.453: [ERR] AccessControlDataBackendManager: no default plugin available!
2017-05-16T23:45:07.943: [CRIT] AccessControlPage: missing default access control data backend

This pull request ( #11 ) solve this issue.

I just received an e-mail about the great news that iTalk will be upgraded and improved. When I tried to download the alpha version I found Windows versions and source code. Will there be a .deb package or do I have to compile myself?

Veyon 4 RC2 (3.99.6)

At first I filled 'Local data' with 10 PC's including mac addresses. Power On (WOL), Run Program and Open website worked. As we have 500+ computers it seemed LDAP was a better idea.

So I configured LDAP, all test are ok except in: Environment settings > Object attributes > Computer MAC address attribute (Value typed in: macAddress)

Computers are populating Veyon Master and it works (so that's all good!), but Wake-On-LAN, Run Program and Open website didn't work
Perhaps because the LDAP search for Computer MAC addresses attribute is not valid.
Active Directory doesn't hold the macadresses?

I get the error when testing:

Could not query any computer MAC addresses. Please check the computer MAC address attribute parameter or enter the name of an existing object.

LDAP error description: 0000208F: NameErr: DSID-0310022D, problem 2006 (BAD_NAME), data 8350, best match of: <computername>
`
Maybe it is possible let Veyon do a ping and arp -a (at the background) to resolve the mac-adresses and work with that instead so WOL will work?

Having issues correctly binding to LDAP.

LDAP server and port are correct. This test is successful.
Fixed base DN is unsuccessful, but when I toggle the option to 'Discover bad DN by naming context' and leave the box blank that test is successful and returns a base DN identical to what I typed in the first time.

I can't get anything under the 'Environment settings' to work correctly, but I'll worry about that after fixing the Base DN issue.

Part of the DN would be dc=local, not sure if that's a problem.

Same problem as in iTALC: When display is locked, a pupil can open the Windows-TaskManager with [Ctrl]+[Alt]+[Del] and then close the display-lock...

Hi
As the topic

I have compiled Veyon 3.99.3 for Linux. I tested in Ubuntu 16.04 (Unity) and Mint 18.1 (KDE).

The VNC connection between veyon-service and veyon-master failed.

When I launch veyon-master, it shows the next message:

2017-05-20T00:44:53.836: [WARN] VeyonVncConnection: VNC message: "VNC server supports protocol version 3.8 (viewer 3.8)"

2017-05-20T00:44:53.837: [WARN] VariantArrayMessage::receive(): could not read message size!

This message repeats many times.

I think the issue is related to libvncserver and RFB 3.8.

I tried to connect to veyon-service with xvnc4viewer, and this is the output:

 xvnc4viewer localhost:11100

I traced it to libvncserver/auth.c.

Does veyon supports android as a client or master?

I've configured the access control and I'm a member of the group that is in the authorized user groups but it denies me access when trying to login? Anyone figure this out?

I have an OU with 10 computers in it, LDAP and Base DN both test successfully. I put the rest of the DN settings in the computer tree under Environment settings and that says 10 computers found, but when I open the Veyon Master nothing is there. What am I missing?

When creating keys in the key file assistant there is only options to create keys for a teacher. is there any way to create roles for keys for other roles?

FindQCA.cmake does not find the library. libqca2-dev is installed. Git repository was with all submodules cloned.

I compiled qca2 form source after that it worked.

wget http://download.kde.org/stable/qca/2.1.3/src/qca-2.1.3.tar.xz
tar -xf qca-2.1.3.tar.xz
cd qca-2.1.3
cmake .
make 
sudo make install

Now cmake .. works fine, but make fails with:

Now i don't know what to do next.

Hello, iTALC also had such a problem, with remote management, if the teacher's computer language is switched to English, then it passes them without problems, that is, in a text document, you can print English letters without problems. But if you switch the language to Russian on the teacher's computer, then it does not transmit anything, and you press the keys, and nothing appears in the text document.

And another question, about the translation of the window of the wizard into Russian, maybe some help is needed? or how?

Hi Tobias,

I was trying your nice new monitoring system, but i have a little problem.
The problem is when i want to insert the public key, generated on the teacher-pc,, into a student-PC a window opens with the message: i don't have the permission to read the key or write permission to the folder C:\ProgramData\Veyon\Keys\ .... on the student-PC.
Sorry for the pic, it's in dutch.
Also when i want to generate new keys in the teacher-PC after the first time. I need to delete the folder in C:\ProgramData\Veyon.... Only then i can generate new keys.

I have problem configuring my veyon setup, I cannot successfully do the remote control. It says Authentication not successful. Can you give a detailed way on how to configure. Anyways great app.

At the LDAP - Enviroment settings - Computer host name attribute
If I use "dNSHostName" and FQDN then the test is working, but "Automaticly switch to current room at start", "Only show current room in computer room management" and "Hide local computer in computer room management" isn't. Although if I use just "name" without FQDN then test and all the above feature is working like it should.

I checked this option in Veyon configurator but local master screen computer is always visible in the master interface.
I entered computer name and adress IP of the local computer in the local data.

Please, can you make possible to load a computers list from a CSV file? Thanks

Do you have any screenshots of the control panel?

I am working in a school where computers are in active directory domain.
Whith Italc the configuration path was saved in /home/localuser/.italc and then i copied the /home/localuser/.italc in the /etc/skel , then when teachers were connected to the domain they could run italc master with all the configuration copied and updated from /home/localuser/.italc

So i tried to run veyon-master with local user and i get this message
. See the capture screen below

i have a error when i try to acess a configurator in xp

" No se encuentra el punto de entrada del procedimiento SHGetKnownFolderPath en la biblioteca de vinculos dinamicos SHELL32.dll"

:)

When the option "automatically switch to current room at start" is checked in veyon-configurator, there is no computer / room displayed in the left frame of the veyon master.
It is necessary to click on the computer rooms button in the left corner below on Veyon master to display the room/computer left frame. But then room and computer aren't automatically checked.
I think it could be a problem for teachers when launching the veyon master. When they used Italc master, the room and computers were automatically visible and displayed in the right frame.
I work with teachers and i know they will be disoriented with this. The easier way for them is to automatically have displayed computers's room in Veyon master. Well maybe it is more a suggestion than a bug report.

Does Veyon support sending WOL packets to all NICs of the master computer?

Background: Most WOL tools only send the WOL packet to the first NIC. When the network is split up into several subnets, you can only send packets to computers in the subnet when you have an interface in that subnet. So an admin computer/VM would have a network interface for each network, but the WOL software needs to send the WOL packet to all interfaces at once.

I just intalled the software as a master and a pop up window keeps going on appaering.

Hello Tobias,

what's the way you are intend to translate veyon to other languages?

In core/resources, there are 2 files :

• lang.ts (e.g. es.ts 🇪🇸)
• veyon.ts

Do you use transifex? How is it works?
Or,
can it be translate in the old way, with Qt Linguist?

Thanks for your time.
Great work! 👏

Hi,

Normaly i used italc on a Windows multiseat computer. Earlier with italc version 1.0.x i can start several italc ica.exe sessions by: ica.exe -ivsport 4001 -isdport 5901 , but with version 3.0.x it doesn't work anymore.

It was working with Italc version 1.0.x, but for now with the new Windows 10 updates it don't works anymore.
So i will use Veyon, because it's not supported by italc anymore.

How can i start Veyon on a other port so i can start Veyon on each workstation to a other port?
Can you make it works.

-> in a multiseat i can also start each workstation with a seperate IP adress, but when i connect form Italc master i only see the first workstation on each IP.
-> is there a way to fix it in veyon, so i can see each workstation for each IP? Or is there a solution to start Veyon on each workstation to a other portnumber?

Thanks in advance
Geert Verbeke

If I wanted to use an attribute like part of the hostname how would I set this up?
I tried: (&(objectcategory=computer)(name=0112))
How do I do this?
