  • 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 4674, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4674'      # process listening on 4674
sudo lsof -nP -i :4674

macOS

sudo lsof -nP -i :4674

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4674 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4674
netstat -ano | findstr :4674

From another machine

nmap -p 4674 -sV <host>
sudo nmap -sU -p 4674 <host>
nc -zv <host> 4674

Block it in the firewall
