We have no specific security note for port 44600. Its risk depends on the program actually listening on it. General advice for other services services:

  • 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.

Is port 44600 TCP or UDP?

Port 44600 is registered for UDP.

Is it safe to open port 44600?

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 44600 is open?

On Linux run "ss -ltnup 'sport = :44600'", on macOS "lsof -nP -i :44600", and on Windows "netstat -ano | findstr :44600" to see the local process. From another machine, "nmap -p 44600 <host>" shows whether it is reachable.
