  • 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.

What is port 8998 used for?

Port 8998 is assigned by IANA to canto-roboflow (Canto RoboFlow Control).

Is port 8998 TCP or UDP?

Port 8998 is registered for TCP.

Is it safe to open port 8998?

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 8998 is open?

On Linux run "ss -ltnup 'sport = :8998'", on macOS "lsof -nP -i :8998", and on Windows "netstat -ano | findstr :8998" to see the local process. From another machine, "nmap -p 8998 <host>" shows whether it is reachable.
