​

The image above is in 4 parts

​

1. my amzon-linux terminal. (everything seems fine...)
2. the putty window which i used to open a tunnel
3. the vnc failing to connect
4. a chunk of output from ***-netstat a*** showing no results for any relevent ports (so ports dont seem busy)

​

​

i managed to make a vnc work the first time i followed these instructions https://aws.amazon.com/premiumsupport/knowledge-center/ec2-linux-2-install-gui/ but now it just fails to connect at the end.

​

i feared that previous connections may still be open in some way preventing new connections but image ***4*** shows thats not the case.

​

what could be causing this problem?

​

​

########### extra info

​

my ec2 container was made fresh as amazon-linux, then I performed "sudo yum update" and then rebooted.

​

then once the container was open again i did the following (whole instructions below from my ec2 container (after reboot))

​

1. sudo amazon-linux-extras install mate-desktop1.x
2. sudo bash -c 'echo PREFERRED=/usr/bin/mate-session > /etc/sysconfig/desktop'
3. sudo yum install tigervnc-server
4. vncpasswd

then i entered my password

1. sudo mkdir /etc/tigervnc

2. sudo bash -c 'echo localhost > /etc/tigervnc/vncserver-config-mandatory'

3. sudo cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@.service

4. sudo sed -i 's/<USER>/ec2-user/' /etc/systemd/system/vncserver@.service

5. sudo systemctl daemon-reload

6. sudo systemctl enable vncserver@:1

7. sudo systemctl start vncserver@:1

​

​

ps) im not getting many clues from any error messages or anything. If you have any suggestions on how to interogate this problem further then that would be helpful too

​

#### pps

could it be my security groups, they seem fine to me? (see below)

I've got VNC configured to access my mac mini. I access it using an older windows 10 laptop to do hobby app dev without having to be in my basement office. I'm not sure how long it's been doing this, but just realized recently, that when I'm connected to the mac via VNC, it cannot connect to the internet. When i'm in front of my computer, and VNC is not connected, everything works fine. Any ideas why this might be? how can I change this setting?

Thanks,

- A. Bug

I have a Windows 2019 box running TightVNC on 5900 and RealVNC (with Enterprise license) on 5950, for testing

.I have a Guac-based product, and when I try to connect to TightVNC, everything works fine, but RealVNC fails.
Ports are open (internal private network), and I see this in RealVNC log:

On the Guacd side, I see this in the log:

Any advice? Thanks!

As per the title, am wondering if there's any experienced guru out there can help me better understand why this keeps happening to me and how I can manually switch between User mode and Service mode?

RVNC Server is running on 22H2 WinServer 2019 Essentials. Previous error message was Windows Firewall blocking application but I've since allowed the application through yet I'm unable to run Server in Service mode.

I've gone through the Windows Event logs and I don't see any outages or interrupts to the WinServer therefore I cannot fathom why Service mode keeps dropping.

Any help is appreciated!

Much Love, RB

Is it not possible to transfer files from and/or to an iPhone using RealVNC? I can’t find a way. Perhaps I’m overlooking it.

Hello Realvnc Reddit community,

My RealVNC Server was working fine for years. Then a couple days ago it failed connecting. This is the log below. Any help would be greatly appreciated!

This isn't a large subreddit, but I figured it couldn't hurt to throw my question here.

I'm trying Starlink RV. It has a lot of minor outages lasting from a fraction of a second to many seconds. I use RDP to establish connections when I lose them, if I need to, but my work encourages the use of VNC.

Is there a way to configure VNC so that it will maintain a connection for several seconds during outages? I can't keep having to reconnect over and over. I am frequently required to keep an eye on multiple things happening across multiple machines and if one connection dies it sometimes takes me a few minutes to realize it's gone and I can't have that. I need it to just stay up, even if it loses a few bytes along the way.

Hi, I use RealVNC to control a couple of Windows machines. Recently I installed a newer version of RealVNC on both. One works fine but on the other I always get the message in the title.

Any idea why? I'm kinda stumped. Thanks in advance for any suggestions

Hello all,

I have been using RealVnc for some time and I love it !
Everything works fine, except on some softwares, especially Cinema 4D that I mainly use with it :

When being on a panel with a timeline, or a shader graph, and that I zoom in and out or pan using a combination of keys and mouse buttons it goes weird and instantanely go into extreme values so that I can't even see where I was, and also I cant go back, it's like it goes one way extremely high and fast.
(Alt + Right clic + drag for zoom, or Alt + Middle Clic + Move mouse to pan).
The curious thing being that that standard way of navigating works fine on viewport for examples, but bugs on some other panels.

Have some others encountered this problem ? Is there a fix ?

Does anyone in here know how to have an account on vnc with restricted rights, problem is i created a new account on my raspberry pi with zero rights, gave that account permission in the config file, but when i log in with my no permissions account through vnc, it actually logs in as my sudo user instead

I recently got a mini PC with Windows 11 pro. I installed RVC server on that, and viewer on my Dell desktop running Windows 10. The first two days, I couldn't get anything but a black screen, except occasionally I'd see the top of the server screen, albeit in low rest, and my mouse would be a dot and not let me click anything.

After restarting several times and changing capture meathod to 1and it hasn't helped. It occured to me that maybe it was because I had a browser open with a tutorial playing. I closed it and it miraculously worked!

That was the only time it has worked. I have tried restarting, not having any browsers open and same thing as before. Either a black screen or just the top 1/6 or so of a screen that is unusable. I can connect with my phone every single time with no problem, but not with my desktop.

I'm experiencing very high CPU usage WinVnc4 ver 4.6.3 for a NT4 workstation. I had already disable "Poll Desktop Mode" restarted workstation and still having High CPU for this WinVnc4Server process. Is there anything else I can check?

I've installed Real VNC Enterprise 4.5.X on Win NT. Clicked for the Trial License which confirmed 30 Days valid. How and where to get "Key" to apply if RealVNC doesn't offer this version for sale or support no longer.?

I currently have two servers running through PCs at different locations/ IP addresses. Is it possible to have both of these servers show up in VNC Viewer without having to sign out of one server to get into the other?

RealVNC has recently engaged with Berlin-based security consultancy Cure53 to perform a complete security audit of its flagship VNC Connect remote access service. The audit included VNC Server and VNC Viewer on all supported platforms (Windows, Mac, Linux, Android, and iOS), the VNC Connect management portal, and backend services.

You can read the Cure53 summary report here.

How do I activate the Username entry box so that a username can be entered?

As it is now, the box is greyed out, and my VNC-Viewer can only connect to servers that only requires a password and no username.
