01 Security

Is port 570 dangerous?

We have no specific security note for port 570. 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 570, and is it reachable?

Linux

sudo ss -ltnup 'sport = :570'      # process listening on 570
sudo lsof -nP -i :570

macOS

sudo lsof -nP -i :570

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 570 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 570
netstat -ano | findstr :570

From another machine

nmap -p 570 -sV <host>
sudo nmap -sU -p 570 <host>
nc -zv <host> 570

Block it in the firewall

sudo ufw deny 570/tcp                                         # Linux (ufw)

04 FAQ
What is port 570 used for?

Port 570 is assigned by IANA to meter (demon).

Is port 570 TCP or UDP?

Port 570 is registered for TCP and UDP.

Is it safe to open port 570?

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 570 is open?

On Linux run "ss -ltnup 'sport = :570'", on macOS "lsof -nP -i :570", and on Windows "netstat -ano | findstr :570" to see the local process. From another machine, "nmap -p 570 <host>" shows whether it is reachable.
