  • 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 11173, and is it reachable?

Linux

sudo ss -ltnup 'sport = :11173'      # process listening on 11173
sudo lsof -nP -i :11173

macOS

sudo lsof -nP -i :11173

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 11173 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 11173
netstat -ano | findstr :11173

From another machine

nmap -p 11173 -sV <host>
nc -zv <host> 11173

Block it in the firewall

sudo ufw deny 11173/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.

How do I check if port 11173 is open?

On Linux run "ss -ltnup 'sport = :11173'", on macOS "lsof -nP -i :11173", and on Windows "netstat -ano | findstr :11173" to see the local process. From another machine, "nmap -p 11173 <host>" shows whether it is reachable.
