  • 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 2645, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2645'      # process listening on 2645
sudo lsof -nP -i :2645

macOS

sudo lsof -nP -i :2645

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2645 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2645
netstat -ano | findstr :2645

From another machine

nmap -p 2645 -sV <host>
sudo nmap -sU -p 2645 <host>
nc -zv <host> 2645

Block it in the firewall

sudo ufw deny 2645/tcp                                         # Linux (ufw)

On Linux run "ss -ltnup 'sport = :2645'", on macOS "lsof -nP -i :2645", and on Windows "netstat -ano | findstr :2645" to see the local process. From another machine, "nmap -p 2645 <host>" shows whether it is reachable.
