03 Check it

Which program uses port 25008, and is it reachable?

Linux

sudo ss -ltnup 'sport = :25008'      # process listening on 25008
sudo lsof -nP -i :25008

macOS

sudo lsof -nP -i :25008

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 25008 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 25008
netstat -ano | findstr :25008

From another machine

nmap -p 25008 -sV <host>
sudo nmap -sU -p 25008 <host>
nc -zv <host> 25008

Block it in the firewall

Is port 25008 TCP or UDP?

Port 25008 is registered for TCP and UDP.

Is it safe to open port 25008?

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 25008 is open?

On Linux run "ss -ltnup 'sport = :25008'", on macOS "lsof -nP -i :25008", and on Windows "netstat -ano | findstr :25008" to see the local process. From another machine, "nmap -p 25008 <host>" shows whether it is reachable.
