NICE DCV connection from OpenVPN and lack of gpu

Question

Hi,

I installed Nice-DCV server on Ubuntu 22.04 on my ec2 instance. The ec2 instance is a m6i, and Nice-DCV installation guide mentions that I can do without gpu.

My first question is: is that true? Can I run a remote desktop client (Nice-DCV-viewer in this case) when my instance does not have a gpu?

Secondly, my company uses openvpn3 for us to connect to ec2 instances, i.e. no public ip, but from my computer I can ssh to the instances using only the private ips. Now, when I try to connect to the instance using Nice-DCV-viewer from my computer (with openvpn running), I still get the message that the connection was refused. What could cause this?

I have setup the security group for TCP/UDP on port 8443 and an IAM role for Nice-DCV license.

Hi Davood,

yes, you can run DCV without GPU - here e.g. is our Ubuntu 22 AMI without GPU: https://aws.amazon.com/marketplace/pp/prodview-iccvz46zbfyb4

Regards connectivity: Does the openvpn allow the incoming TCP 8443 connection? The security group setting should not play a role here. You can test connectivity from your DCV client machine with the command

telnet YOUR_DCV_SERVER 8443

If that works well you should be able to connect with the DCV client as well.

Best regards,
Karsten
