Is port 45514 dangerous?

We have no specific security note for port 45514. 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.

03 Check it

Which program uses port 45514, and is it reachable?

Linux

sudo ss -ltnup 'sport = :45514'      # process listening on 45514
sudo lsof -nP -i :45514

macOS

sudo lsof -nP -i :45514

04 FAQ
What is port 45514 used for?

Port 45514 is assigned by IANA to cloudcheck (ASSIA CloudCheck WiFi Management System), cloudcheck-ping (ASSIA CloudCheck WiFi Management keepalive).

Is port 45514 TCP or UDP?

Port 45514 is registered for TCP and UDP.

Is it safe to open port 45514?

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 45514 is open?

On Linux run "ss -ltnup 'sport = :45514'", on macOS "lsof -nP -i :45514", and on Windows "netstat -ano | findstr :45514" to see the local process. From another machine, "nmap -p 45514 <host>" shows whether it is reachable.
