Is port 5069 dangerous?

We have no specific security note for port 5069. 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 5069, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5069'      # process listening on 5069
sudo lsof -nP -i :5069

macOS

sudo lsof -nP -i :5069

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5069 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5069
netstat -ano | findstr :5069

From another machine

nmap -p 5069 -sV <host>
sudo nmap -sU -p 5069 <host>
nc -zv <host> 5069

Block it in the firewall

sudo ufw deny 5069/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5069" -Direction Inbound -LocalPort 5069 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5069 used for?

Port 5069 is assigned by IANA to i-net-2000-npr (I/Net 2000-NPR).

Is port 5069 TCP or UDP?

Port 5069 is registered for TCP and UDP.

Is it safe to open port 5069?

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 5069 is open?

On Linux run "ss -ltnup 'sport = :5069'", on macOS "lsof -nP -i :5069", and on Windows "netstat -ano | findstr :5069" to see the local process. From another machine, "nmap -p 5069 <host>" shows whether it is reachable.
