rfbCheckPasswordByList()는 계정-패스워드 쌍으로 되어있는 값을 이용하여 로그인을 구현하는 기본 함수이다.
희망(?)을 가졌던 newClientHook 이벤트는 시도때도 없이 발생했고(원래 기대했던 것은 로그인 시 1회)
로그인 별로 어떤 계정이 로그인 성공,실패 했는지는 함수를 확장해서 만들어야 할 듯..
newClientHook 에서도 cl->viewOnly가 설정되지 않는 걸 보면, vnc client 측의 설정과는 별개 인 듯

revind / revind.so / run / websockify 는 websockify 에서 나온거
libvncserver 와 noVNC와 websockify 의 조합으로 어찌 되긴 하는데..

웹 브라우저에서 http://ip:5800 으로 접속하면 아래와 같이 뜨고
별다른 설정을 하지 않았다면 wss(websocket secure)를 안될테니 위에 "Click here to connect using noVNC"를 누른다.
약간의 시간을 기다리면(libvncserver의 웹 서버가 느린지 파일 전송이 좀 느리다)
아래와 같이 쨘~

한번 되더니 websockify 없이도 되네.. 머지?

runInBackground 의 값을 TRUE 로 해주면 웹 서버가 작동을 안한다 -_-
어떻게 해야 할까..

내용이 부실한데 드래그를 구현하려면 down 이벤트를 보고 해당 버튼의 마스크가 사라질때 까지 보고 있어야 할 듯?
I had the same problem using VNC from my Chromebook and after updating to Ubuntu 14.04 LTS. I used the suggestion of the dconf-editor -> org.gnome.desktop.remote-access then "require-encryption = NO"
