  • 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 1769, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1769'      # process listening on 1769
sudo lsof -nP -i :1769

macOS

sudo lsof -nP -i :1769

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1769 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1769
netstat -ano | findstr :1769

From another machine

nmap -p 1769 -sV <host>
sudo nmap -sU -p 1769 <host>
nc -zv <host> 1769

Block it in the firewall

sudo ufw deny 1769/tcp                                         # Linux (ufw)

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

On Linux run "ss -ltnup 'sport = :1769'", on macOS "lsof -nP -i :1769", and on Windows "netstat -ano | findstr :1769" to see the local process. From another machine, "nmap -p 1769 <host>" shows whether it is reachable.
