  • 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 2984, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2984'      # process listening on 2984
sudo lsof -nP -i :2984

macOS

sudo lsof -nP -i :2984

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2984 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2984
netstat -ano | findstr :2984

From another machine

nmap -p 2984 -sV <host>
sudo nmap -sU -p 2984 <host>
nc -zv <host> 2984

Block it in the firewall

sudo ufw deny 2984/tcp                                         # Linux (ufw)
