01 Security

Is port 5969 dangerous?

We have no specific security note for port 5969. 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 5969, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5969'      # process listening on 5969
sudo lsof -nP -i :5969

macOS

sudo lsof -nP -i :5969

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5969 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5969
netstat -ano | findstr :5969

From another machine

nmap -p 5969 -sV <host>
sudo nmap -sU -p 5969 <host>
nc -zv <host> 5969

Block it in the firewall

sudo ufw deny 5969/tcp                                         # Linux (ufw)

04 FAQ
What is port 5969 used for?

Port 5969 is assigned by IANA to mppolicy-mgr (mppolicy-mgr).

Is port 5969 TCP or UDP?

Port 5969 is registered for TCP and UDP.

Is it safe to open port 5969?

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 5969 is open?

On Linux run "ss -ltnup 'sport = :5969'", on macOS "lsof -nP -i :5969", and on Windows "netstat -ano | findstr :5969" to see the local process. From another machine, "nmap -p 5969 <host>" shows whether it is reachable.
