03 Check it

Which program uses port 8614, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8614'      # process listening on 8614
sudo lsof -nP -i :8614

macOS

sudo lsof -nP -i :8614

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8614 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8614
netstat -ano | findstr :8614

From another machine

nmap -p 8614 -sV <host>
sudo nmap -sU -p 8614 <host>
nc -zv <host> 8614

Block it in the firewall

sudo ufw deny 8614/tcp                                         # Linux (ufw)

Is port 8614 TCP or UDP?

Port 8614 is registered for TCP and UDP.

Is it safe to open port 8614?

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.
