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.
