Hello Everyone,

I need your help to resolve the issue with VNC - Remote desktop connection. I upgraded my ubuntu from 12.04 LTS to 14.04 (Alpha) today. I was able to connect to Ubuntu desktop (12.04) from my IPAD using HippoRemote LIte or RealVNC before. But after up-gradation to 14.04, this is not working all of a sudden. I tried many options to the best of my knowledge, including but not limited to, changing / restarting my router settings, reinstalling VNC server etc, changing default port 5900 to different and port forwarding etc. But none of them worked and I am unable to connect to desktop remotely using Ipad.

It seems VINO is not listening to ipv4 connections, may be it conflicts with ipv6. Could any of you please help me how I can get through this.

nims@reny:~$ netstat -alpn | grep :5900
