  • 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 1980, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1980'      # process listening on 1980
sudo lsof -nP -i :1980

macOS

sudo lsof -nP -i :1980

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1980 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1980
netstat -ano | findstr :1980

From another machine

nmap -p 1980 -sV <host>
sudo nmap -sU -p 1980 <host>
nc -zv <host> 1980

Block it in the firewall

sudo ufw deny 1980/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1980" -Direction Inbound -LocalPort 1980 -Protocol TCP -Action Block  # Windows

On Linux run "ss -ltnup 'sport = :1980'", on macOS "lsof -nP -i :1980", and on Windows "netstat -ano | findstr :1980" to see the local process. From another machine, "nmap -p 1980 <host>" shows whether it is reachable.
