I am developing an application that uses x11vnc in the background and I would like to know how many users are currently connected. I have reviewed the list of commands but I have not found anything for that purpose.

Any ideas?

  • Thank you! I finally used this code: netstat -anpt | grep SERVER_PORT | grep 'ESTABLISHED' | grep -c 'tcp' That is, filters the number of connections established with my VNC server (usually SERVER_PORT is 5900) and then counts the number of times that "tcp" appers in these results (which is 1 per client). – Javi Jun 4 '19 at 14:50

You can use the next interface

x11vnc -query client_count -display :0
