  • 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 2546, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2546'      # process listening on 2546
sudo lsof -nP -i :2546

macOS

sudo lsof -nP -i :2546

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2546 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2546
netstat -ano | findstr :2546

From another machine

nmap -p 2546 -sV <host>
sudo nmap -sU -p 2546 <host>
nc -zv <host> 2546

Block it in the firewall

sudo ufw deny 2546/tcp                                         # Linux (ufw)
