Is it safe to open port 5050?
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. Require authentication on cameras and media servers.
How do I check if port 5050 is open?
On Linux run "ss -ltnup 'sport = :5050'", on macOS "lsof -nP -i :5050", and on Windows "netstat -ano | findstr :5050" to see the local process. From another machine, "nmap -p 5050 <host>" shows whether it is reachable.
