01 Security

Is port 2069 dangerous?

We have no specific security note for port 2069. Its risk depends on the program actually listening on it. General advice for web services:

  • Serve it over HTTPS only and check the HTTP security headers.
  • Keep admin consoles and development servers off the Internet.
  • Patch the application server and remove default credentials and sample apps.

03 Check it

Which program uses port 2069, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2069'      # process listening on 2069
sudo lsof -nP -i :2069

macOS

sudo lsof -nP -i :2069

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2069 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2069
netstat -ano | findstr :2069

From another machine

nmap -p 2069 -sV <host>
sudo nmap -sU -p 2069 <host>
nc -zv <host> 2069

Block it in the firewall

sudo ufw deny 2069/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2069" -Direction Inbound -LocalPort 2069 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2069 used for?

Port 2069 is assigned by IANA to event-port (HTTP Event Port).

Is port 2069 TCP or UDP?

Port 2069 is registered for TCP and UDP.

Is it safe to open port 2069?

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. Serve it over HTTPS only and check the HTTP security headers.

How do I check if port 2069 is open?

On Linux run "ss -ltnup 'sport = :2069'", on macOS "lsof -nP -i :2069", and on Windows "netstat -ano | findstr :2069" to see the local process. From another machine, "nmap -p 2069 <host>" shows whether it is reachable.
