  • 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 2954, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2954'      # process listening on 2954
sudo lsof -nP -i :2954

macOS

sudo lsof -nP -i :2954

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2954 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2954
netstat -ano | findstr :2954

From another machine

nmap -p 2954 -sV <host>
sudo nmap -sU -p 2954 <host>
nc -zv <host> 2954

Block it in the firewall
