  • 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 4124, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4124'      # process listening on 4124
sudo lsof -nP -i :4124

macOS

sudo lsof -nP -i :4124

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4124 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4124
netstat -ano | findstr :4124

From another machine

nmap -p 4124 -sV <host>
sudo nmap -sU -p 4124 <host>
nc -zv <host> 4124

Block it in the firewall

sudo ufw deny 4124/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4124" -Direction Inbound -LocalPort 4124 -Protocol TCP -Action Block  # Windows
