01 Security

Is port 3571 dangerous?

We have no specific security note for port 3571. 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 3571, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3571'      # process listening on 3571
sudo lsof -nP -i :3571

macOS

sudo lsof -nP -i :3571

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3571 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3571
netstat -ano | findstr :3571

From another machine

nmap -p 3571 -sV <host>
sudo nmap -sU -p 3571 <host>
nc -zv <host> 3571

Block it in the firewall

sudo ufw deny 3571/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3571" -Direction Inbound -LocalPort 3571 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3571 used for?

Port 3571 is assigned by IANA to megardsvr-port (MegaRAID Server Port).

Is port 3571 TCP or UDP?

Port 3571 is registered for TCP and UDP.

Is it safe to open port 3571?

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 3571 is open?

On Linux run "ss -ltnup 'sport = :3571'", on macOS "lsof -nP -i :3571", and on Windows "netstat -ano | findstr :3571" to see the local process. From another machine, "nmap -p 3571 <host>" shows whether it is reachable.
