Is port 24005 dangerous?

We have no specific security note for port 24005. 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 24005, and is it reachable?

Linux

sudo ss -ltnup 'sport = :24005'      # process listening on 24005
sudo lsof -nP -i :24005

macOS

sudo lsof -nP -i :24005

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 24005 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 24005
netstat -ano | findstr :24005

From another machine

sudo nmap -sU -p 24005 <host>
nc -zv <host> 24005

Block it in the firewall

sudo ufw deny 24005/tcp                                         # Linux (ufw)

Is port 24005 TCP or UDP?

Port 24005 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 24005 is open?

On Linux run "ss -ltnup 'sport = :24005'", on macOS "lsof -nP -i :24005", and on Windows "netstat -ano | findstr :24005" to see the local process. From another machine, "nmap -p 24005 <host>" shows whether it is reachable.
