01 Security

Is port 8033 dangerous?

We have no specific security note for port 8033. 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 8033, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8033'      # process listening on 8033
sudo lsof -nP -i :8033

macOS

sudo lsof -nP -i :8033

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8033 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8033
netstat -ano | findstr :8033

From another machine

nmap -p 8033 -sV <host>
sudo nmap -sU -p 8033 <host>
nc -zv <host> 8033

Block it in the firewall

sudo ufw deny 8033/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8033" -Direction Inbound -LocalPort 8033 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8033 used for?

Port 8033 is assigned by IANA to mindprint (MindPrint).

Is port 8033 TCP or UDP?

Port 8033 is registered for TCP and UDP.

Is it safe to open port 8033?

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 8033 is open?

On Linux run "ss -ltnup 'sport = :8033'", on macOS "lsof -nP -i :8033", and on Windows "netstat -ano | findstr :8033" to see the local process. From another machine, "nmap -p 8033 <host>" shows whether it is reachable.
