Is there a free linux (Ubuntu and/or RHEL) vncserver which works with IPv6? From what I can see, the normal VNC RPMs contain the Free Edition of RealVNC which does not have IPv6 support. The Enterprise Edition looks like it supports IPv6, but that costs $50 a server. RealVNC is also the only program that I could find which supported IPv6 as a Windows client, and that's also $50.00, unfortunately, I can't afford both client and server, especially since I have multiple IPv6 servers that I want to interact with.
There was a TightVNC port with IPv6 (http://jungla.dit.upm.es/~acosta/paginas/vncIPv6.html
), but that web page is dead.
