01 Security

Is port 13785 dangerous?

We have no specific security note for port 13785. Its risk depends on the program actually listening on it. General advice for databases & caches services:

  • Bind the service to localhost or a private network, never to a public address.
  • Enable authentication, use per-application accounts and require TLS.
  • Watch for exposed Docker ports: publish them on 127.0.0.1 only.

Is port 13785 TCP or UDP?

Port 13785 is registered for TCP and UDP.

Is it safe to open port 13785?

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. Bind the service to localhost or a private network, never to a public address.

How do I check if port 13785 is open?

On Linux run "ss -ltnup 'sport = :13785'", on macOS "lsof -nP -i :13785", and on Windows "netstat -ano | findstr :13785" to see the local process. From another machine, "nmap -p 13785 <host>" shows whether it is reachable.
