01 Security

Is port 1571 dangerous?

We have no specific security note for port 1571. Its risk depends on the program actually listening on it. General advice for databases & caches services:

  • Bind the service to localhost or a private network, never to a public address.
  • Enable authentication, use per-application accounts and require TLS.
  • Watch for exposed Docker ports: publish them on 127.0.0.1 only.

03 Check it

Which program uses port 1571, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1571'      # process listening on 1571
sudo lsof -nP -i :1571

macOS

sudo lsof -nP -i :1571

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1571 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1571
netstat -ano | findstr :1571

From another machine

nmap -p 1571 -sV <host>
sudo nmap -sU -p 1571 <host>
nc -zv <host> 1571

Block it in the firewall

sudo ufw deny 1571/tcp                                         # Linux (ufw)

04 FAQ
What is port 1571 used for?

Port 1571 is assigned by IANA to rdb-dbs-disp (Oracle Remote Data Base).

Is port 1571 TCP or UDP?

Port 1571 is registered for TCP and UDP.

Is it safe to open port 1571?

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. Bind the service to localhost or a private network, never to a public address.

How do I check if port 1571 is open?

On Linux run "ss -ltnup 'sport = :1571'", on macOS "lsof -nP -i :1571", and on Windows "netstat -ano | findstr :1571" to see the local process. From another machine, "nmap -p 1571 <host>" shows whether it is reachable.
