03 Check it

Which program uses port 9593, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9593'      # process listening on 9593
sudo lsof -nP -i :9593

macOS

sudo lsof -nP -i :9593

netstat -ano | findstr :9593

From another machine

nmap -p 9593 -sV <host>
sudo nmap -sU -p 9593 <host>
nc -zv <host> 9593

Block it in the firewall

Is port 9593 TCP or UDP?

Port 9593 is registered for TCP and UDP.

Is it safe to open port 9593?

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 9593 is open?

On Linux run "ss -ltnup 'sport = :9593'", on macOS "lsof -nP -i :9593", and on Windows "netstat -ano | findstr :9593" to see the local process. From another machine, "nmap -p 9593 <host>" shows whether it is reachable.
