Hi Reza, The console access for KVM VMs has been secured since CloudStack 4.18.0 and it is using the certificates provided by the CA Framework to secure the connections. This is configured automatically by CloudStack following the procedure described on the design document: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Secure+KVM+VNC+connection+using+the+CA+framework
I think the problem is that you are trying to use the incorrect VEncrypt type, you should use X509Vnc instead of TLSVnc. I’m not sure about the tigervnc parameters but you may also check for a way to provide a path for the certificates Regards, Nicolas Vazquez From: R A <jarhe...@hotmail.de> Date: Thursday, 18 July 2024 at 18:35 To: users@cloudstack.apache.org <users@cloudstack.apache.org> Subject: VNC with tigervnc Hello guys, i am trying to setup a vnc connection to the vms via a "normal" vncclient like tigervnc. vncviewer -SecurityTypes=VeNCrypt,TLSVnc 172.17.10.10:5903 When connecting I get this message: An unexpected error occurred when communicating with the server: Authentication failure: No valid VeNCrypt sub-type Does anyone has some advice how to get this working?
