Error in tightVNC viewer no connection could be made because the target machine actively refused it

Question

I am using TightVNC viewer from Window7 to connect the Ubuntu machine. I got the error "Error in tightVNC viewer no connection could be made because the target machine actively refused it.

I do not have any firewall setup.

When i run, ps -ef | grep vnc:: i get

root      5265  4521  0 15:57 pts/1    00:00:00 sudo x11vnc -safer -localhost -nopw -accept popup:0 -once -viewonly -display :0

mmm 5890  5269  0 16:06 pts/2    00:00:00 grep --color=auto vnc

On, x11vnc -forever -usepw -httpdir /usr/share/vnc-java/ -httpport 5800

23/05/2014 16:16:12 * XOpenDisplay failed (:0)

* x11vnc was unable to open the X DISPLAY: ":0", it cannot continue. * There may be "Xlib:" error messages above with details about the failure.

I am not sure where is the issue.

I tried connecting like, 171.69.35.33 171.69.35.33:5900 171.69.35.33::5901

f4rom tightvnc viewer.

Solution

sudo apt-get install x11vnc

x11vnc -storepasswd

x11vnc -usepw

sudo x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -usepw

This solved my issue.

this fixed a problem that I'd been messing with for a good bit of time; wish I could upvote more than once

vncserver -list vncserver -kill :1 (kill the current connection) vncserver :1 geometry 1024x768 (recreate the connection) this worked for me..
