  • 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 7393, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7393'      # process listening on 7393
sudo lsof -nP -i :7393

macOS

sudo lsof -nP -i :7393

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7393 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7393
netstat -ano | findstr :7393

From another machine

nmap -p 7393 -sV <host>
sudo nmap -sU -p 7393 <host>
nc -zv <host> 7393

Block it in the firewall

sudo ufw deny 7393/tcp                                         # Linux (ufw)
