  • 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 2924, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2924'      # process listening on 2924
sudo lsof -nP -i :2924

macOS

sudo lsof -nP -i :2924

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2924 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2924
netstat -ano | findstr :2924

From another machine

nmap -p 2924 -sV <host>
sudo nmap -sU -p 2924 <host>
nc -zv <host> 2924

Block it in the firewall

sudo ufw deny 2924/tcp                                         # Linux (ufw)

On Linux run "ss -ltnup 'sport = :2924'", on macOS "lsof -nP -i :2924", and on Windows "netstat -ano | findstr :2924" to see the local process. From another machine, "nmap -p 2924 <host>" shows whether it is reachable.
