If you’re an OnApp user you probably know you can make a VNC connection to your VM’s using the Control Panel. This uses a java applet in your browser as the VNC client.
Wouldn’t it be nice to use your own VNC client (like Remotix) instead?
In fact, you can, but OnApp spawns a VNC server on a (somewhat) random port and a new random VNC password for each sessions which you’ll have to figure out before setting up your connection.
