Is port 2505 dangerous?

We have no specific security note for port 2505. 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.

03 Check it

Which program uses port 2505, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2505'      # process listening on 2505
sudo lsof -nP -i :2505

macOS

sudo lsof -nP -i :2505

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2505 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2505
netstat -ano | findstr :2505

From another machine

nmap -p 2505 -sV <host>
sudo nmap -sU -p 2505 <host>
nc -zv <host> 2505

Block it in the firewall

sudo ufw deny 2505/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2505" -Direction Inbound -LocalPort 2505 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2505 used for?

Port 2505 is assigned by IANA to ppcontrol (PowerPlay Control).

Is port 2505 TCP or UDP?

Port 2505 is registered for TCP and UDP.

Is it safe to open port 2505?

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 2505 is open?

On Linux run "ss -ltnup 'sport = :2505'", on macOS "lsof -nP -i :2505", and on Windows "netstat -ano | findstr :2505" to see the local process. From another machine, "nmap -p 2505 <host>" shows whether it is reachable.
