This has been driving me nuts since last night. It turns out that on my FC6 machine "localhost" doesn't resolve properly. Everything was listening on port 5900, but it looks like vncviewer etc just couldn't work out to connect to 127.0.0.1. Using "vncviewer 127.0.0.1" worked fine. In resolve.conf I had: ::1 lair6.remcc.org lair6 localhost.localdomain localhost I changed this to 127.0.0.1 lair6.remcc.org lair6 localhost.localdomain localhost Hopefully this is the same problem you're having.
