I spent several hours getting a VNC connection to vino on a fresh install of f17. I set Desktop Sharing Preferences on f17, but could not connect from tightVNC on Windows 7. My tightVNC on Windows 7 returned error: "A socket operaton was attempted to an unreachable host." I could ping from Window 7 to f17 successfully.
I finally figured out that I needed to allow port 5900 in Firewall Configuration on f17. This is unlike my experience installing tightVNC on Windows 7: the installer modified the firewall to allow connection.
My question is: was there a guide or FAQ that could have let me know that a manual modification to the firewall would be required in order to use vino?
If I can find a guide that will tell me that, I feel I may find answers to many other questions I have.
