VNC to Kali Linux

[Michael Abernathy]

I just spun up my first Kali Linux instance and am trying to connect to the gui from my home windows machine using VNC Viewer but I am getting "Timed out waiting for a response from the computer"

I have created a firewall rule to allow TCP:5901-5910, tagged it, and applied that tag to my kali server.

I checked the iptables: 

$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         
Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Ensured the connection is allowed:

$ nc XXX.XXX.XXX.XXX 5901
RFB 003.008

I am really not sure what I am missing.

Any help would be greatly appreciated.

Thanks,

Mike

Hello Michael,

It seems that you ran netcat from inside the VM to ensure the connection is locally allowed. Can you make sure that the firewall rule you've created for VNC service is made for the VPC network which the VM is attached to?

Kamran,

The firewall rule is for the default network.

Is the VM created on the default network?  

If you require further assistance please feel free to email me your project ID and the VM name privately.
