03 Check it

Which program uses port 13216, and is it reachable?

Linux

sudo ss -ltnup 'sport = :13216'      # process listening on 13216
sudo lsof -nP -i :13216

macOS

sudo lsof -nP -i :13216

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 13216 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 13216
netstat -ano | findstr :13216

From another machine

nmap -p 13216 -sV <host>
sudo nmap -sU -p 13216 <host>
nc -zv <host> 13216

Block it in the firewall

sudo ufw deny 13216/tcp                                         # Linux (ufw)

04 FAQ
What is port 13216 used for?

Port 13216 is assigned by IANA to bcslogc (Black Crow Software application logging).

Is port 13216 TCP or UDP?

Port 13216 is registered for TCP and UDP.

Is it safe to open port 13216?

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. Restrict management and monitoring protocols to the monitoring network.

How do I check if port 13216 is open?

On Linux run "ss -ltnup 'sport = :13216'", on macOS "lsof -nP -i :13216", and on Windows "netstat -ano | findstr :13216" to see the local process. From another machine, "nmap -p 13216 <host>" shows whether it is reachable.
