03 Check it

Which program uses port 5989, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5989'      # process listening on 5989
sudo lsof -nP -i :5989

macOS

sudo lsof -nP -i :5989

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5989 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5989
netstat -ano | findstr :5989

From another machine

nmap -p 5989 -sV <host>
sudo nmap -sU -p 5989 <host>
nc -zv <host> 5989

Block it in the firewall

04 FAQ
What is port 5989 used for?

Port 5989 is assigned by IANA to wbem-https (WBEM CIM-XML (HTTPS)).

Is port 5989 TCP or UDP?

Port 5989 is registered for TCP and UDP.

Is it safe to open port 5989?

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. Restrict management and monitoring protocols to the monitoring network.

How do I check if port 5989 is open?

On Linux run "ss -ltnup 'sport = :5989'", on macOS "lsof -nP -i :5989", and on Windows "netstat -ano | findstr :5989" to see the local process. From another machine, "nmap -p 5989 <host>" shows whether it is reachable.
