[ubuntu] x11vnc - do not ask to confirm

view story

http://ubuntuforums.org – Hi all, After I establish an SSH tunnel (using Putty) from my Windows machine at work and then try to connect using tightvncviewer to my ubuntu 12.04 machine at home all I get is a black screen. Meanwhile the client machine pops up a message asking to "allow" or "refuse" my connection. And that's it, I get stuck there and am unable to connect remotley. What's interesting is that if I try to connect to the same machine from another machine at home i.e. over LAN (without the need for SSH) it connects without asking me to confirm the connection. Can anyone please help (Hardware)
