enable clipboard tranfer in linux vncserver

Being not able to copy/paste from linux machine through vncviewer was bugging me for a couple of day :(

Here is the solution:

vncconfig -nowin &
done...

vi ~/.vnc/xstartup
>>> vncconfig -nowin &
restart the linux machine...

step to kill a running vncserver:

cat ~/.vnc/hostname.4.pid

vncserver -kill :4
done...
