OK, the ports 5905 and 5906 are open and in use locally. Unfortunately, 
your previous scan results didn't show the status of those same ports 
from the remote machine.  Try the following command on the remote machine:

nmap -v -n -P0 -p5905-5906 193.49.194.19

If the ports aren't showing up as "open" then it is your firewall that 
is the problem.  Make sure you open those ports for both inbound and 
outbound traffic in your firewall configuration on the system running 
the vncserver.
