  • 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 38865, and is it reachable?

Linux

sudo ss -ltnup 'sport = :38865'      # process listening on 38865
sudo lsof -nP -i :38865

macOS

sudo lsof -nP -i :38865

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 38865 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 38865
netstat -ano | findstr :38865

From another machine

nmap -p 38865 -sV <host>
nc -zv <host> 38865

Block it in the firewall

sudo ufw deny 38865/tcp                                         # Linux (ufw)

Is port 38865 TCP or UDP?

Port 38865 is registered for TCP.

Is it safe to open port 38865?

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 38865 is open?

On Linux run "ss -ltnup 'sport = :38865'", on macOS "lsof -nP -i :38865", and on Windows "netstat -ano | findstr :38865" to see the local process. From another machine, "nmap -p 38865 <host>" shows whether it is reachable.
