Is port 4025 dangerous?

We have no specific security note for port 4025. Its risk depends on the program actually listening on it. General advice for other services services:

  • 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.

sudo lsof -nP -i :4025

macOS

sudo lsof -nP -i :4025

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4025 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4025
netstat -ano | findstr :4025

From another machine

nmap -p 4025 -sV <host>
sudo nmap -sU -p 4025 <host>
nc -zv <host> 4025

Block it in the firewall

sudo ufw deny 4025/tcp                                         # Linux (ufw)

04 FAQ
What is port 4025 used for?

Port 4025 is assigned by IANA to partimage (Partition Image Port).

Is port 4025 TCP or UDP?

Port 4025 is registered for TCP and UDP.

Is it safe to open port 4025?

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 4025 is open?

On Linux run "ss -ltnup 'sport = :4025'", on macOS "lsof -nP -i :4025", and on Windows "netstat -ano | findstr :4025" to see the local process. From another machine, "nmap -p 4025 <host>" shows whether it is reachable.
