Is port 2847 dangerous?

We have no specific security note for port 2847. 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 2847, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2847'      # process listening on 2847
sudo lsof -nP -i :2847

macOS

sudo lsof -nP -i :2847

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2847 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2847
netstat -ano | findstr :2847

From another machine

nmap -p 2847 -sV <host>
sudo nmap -sU -p 2847 <host>
nc -zv <host> 2847

Block it in the firewall

sudo ufw deny 2847/tcp                                         # Linux (ufw)

Port 2847 is assigned by IANA to aimpp-port-req (AIMPP Port Req).

Is port 2847 TCP or UDP?

Port 2847 is registered for TCP and UDP.

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 2847 is open?

On Linux run "ss -ltnup 'sport = :2847'", on macOS "lsof -nP -i :2847", and on Windows "netstat -ano | findstr :2847" to see the local process. From another machine, "nmap -p 2847 <host>" shows whether it is reachable.
