01 Security

Is port 24323 dangerous?

We have no specific security note for port 24323. 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 24323, and is it reachable?

Linux

sudo ss -ltnup 'sport = :24323'      # process listening on 24323
sudo lsof -nP -i :24323

macOS

sudo lsof -nP -i :24323

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 24323 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 24323
netstat -ano | findstr :24323

From another machine

nmap -p 24323 -sV <host>
nc -zv <host> 24323

Block it in the firewall

sudo ufw deny 24323/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 24323" -Direction Inbound -LocalPort 24323 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 24323 used for?

Port 24323 is assigned by IANA to vrmg-ip (Verimag mobile class protocol over TCP).

Is port 24323 TCP or UDP?

Port 24323 is registered for TCP.

Is it safe to open port 24323?

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 24323 is open?

On Linux run "ss -ltnup 'sport = :24323'", on macOS "lsof -nP -i :24323", and on Windows "netstat -ano | findstr :24323" to see the local process. From another machine, "nmap -p 24323 <host>" shows whether it is reachable.
