  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

netstat -ano | findstr :7741

From another machine

nmap -p 7741 -sV <host>
sudo nmap -sU -p 7741 <host>
nc -zv <host> 7741
