01 Security

Is port 33060 dangerous?

We have no specific security note for port 33060. 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 33060, and is it reachable?

Linux

sudo ss -ltnup 'sport = :33060'      # process listening on 33060
sudo lsof -nP -i :33060

macOS

sudo lsof -nP -i :33060

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 33060 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 33060
netstat -ano | findstr :33060

From another machine

nmap -p 33060 -sV <host>
nc -zv <host> 33060

Block it in the firewall

sudo ufw deny 33060/tcp                                         # Linux (ufw)

04 FAQ
What is port 33060 used for?

Port 33060 is assigned by IANA to mysqlx (MySQL Database Extended Interface).

Is port 33060 TCP or UDP?

Port 33060 is registered for TCP.

Is it safe to open port 33060?

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 33060 is open?

On Linux run "ss -ltnup 'sport = :33060'", on macOS "lsof -nP -i :33060", and on Windows "netstat -ano | findstr :33060" to see the local process. From another machine, "nmap -p 33060 <host>" shows whether it is reachable.
