01 Security

Is port 24001 dangerous?

We have no specific security note for port 24001. 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 24001, and is it reachable?

Linux

sudo ss -ltnup 'sport = :24001'      # process listening on 24001
sudo lsof -nP -i :24001

macOS

sudo lsof -nP -i :24001

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 24001 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 24001
netstat -ano | findstr :24001

From another machine

nmap -p 24001 -sV <host>
sudo nmap -sU -p 24001 <host>
nc -zv <host> 24001

Block it in the firewall

sudo ufw deny 24001/tcp                                         # Linux (ufw)

04 FAQ
What is port 24001 used for?

Port 24001 is assigned by IANA to med-fsp-rx (med-fsp-rx).

Is port 24001 TCP or UDP?

Port 24001 is registered for TCP and UDP.

Is it safe to open port 24001?

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 24001 is open?

On Linux run "ss -ltnup 'sport = :24001'", on macOS "lsof -nP -i :24001", and on Windows "netstat -ano | findstr :24001" to see the local process. From another machine, "nmap -p 24001 <host>" shows whether it is reachable.
