  • 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.

03 Check it

Which program uses port 9994, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9994'      # process listening on 9994
sudo lsof -nP -i :9994

macOS

sudo lsof -nP -i :9994

Windows (PowerShell)

netstat -ano | findstr :9994

From another machine

nmap -p 9994 -sV <host>
sudo nmap -sU -p 9994 <host>
nc -zv <host> 9994

Is port 9994 TCP or UDP?

Port 9994 is registered for TCP and UDP.

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 9994 is open?

On Linux run "ss -ltnup 'sport = :9994'", on macOS "lsof -nP -i :9994", and on Windows "netstat -ano | findstr :9994" to see the local process. From another machine, "nmap -p 9994 <host>" shows whether it is reachable.
