01 Security

Is port 9380 dangerous?

We have no specific security note for port 9380. 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 9380, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9380'      # process listening on 9380
sudo lsof -nP -i :9380

macOS

sudo lsof -nP -i :9380

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9380 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9380
netstat -ano | findstr :9380

From another machine

nmap -p 9380 -sV <host>
sudo nmap -sU -p 9380 <host>
nc -zv <host> 9380

Block it in the firewall

sudo ufw deny 9380/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 9380" -Direction Inbound -LocalPort 9380 -Protocol TCP -Action Block  # Windows

What is port 9380 used for?

Port 9380 is assigned by IANA to boxp (Brivs! Open Extensible Protocol).

Is port 9380 TCP or UDP?

Port 9380 is registered for TCP and UDP.

Is it safe to open port 9380?

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 9380 is open?

On Linux run "ss -ltnup 'sport = :9380'", on macOS "lsof -nP -i :9380", and on Windows "netstat -ano | findstr :9380" to see the local process. From another machine, "nmap -p 9380 <host>" shows whether it is reachable.
