  • 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 24386, and is it reachable?

Linux

sudo ss -ltnup 'sport = :24386'      # process listening on 24386
sudo lsof -nP -i :24386

macOS

sudo lsof -nP -i :24386

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 24386 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 24386
netstat -ano | findstr :24386

From another machine

nmap -p 24386 -sV <host>
sudo nmap -sU -p 24386 <host>
nc -zv <host> 24386

Block it in the firewall

04 FAQ
What is port 24386 used for?

Port 24386 is assigned by IANA to intel_rci (Intel RCI), intel-rci (Intel RCI IANA assigned this well-formed service name as a replacement for "intel_rci".).

Is port 24386 TCP or UDP?

Port 24386 is registered for TCP and UDP.

Is it safe to open port 24386?

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 24386 is open?

On Linux run "ss -ltnup 'sport = :24386'", on macOS "lsof -nP -i :24386", and on Windows "netstat -ano | findstr :24386" to see the local process. From another machine, "nmap -p 24386 <host>" shows whether it is reachable.
