Is port 1924 dangerous?

We have no specific security note for port 1924. 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 1924, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1924'      # process listening on 1924
sudo lsof -nP -i :1924

macOS

sudo lsof -nP -i :1924

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1924 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1924
netstat -ano | findstr :1924

From another machine

nmap -p 1924 -sV <host>
sudo nmap -sU -p 1924 <host>
nc -zv <host> 1924

Block it in the firewall

sudo ufw deny 1924/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1924" -Direction Inbound -LocalPort 1924 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1924 used for?

Port 1924 is assigned by IANA to xiip (XIIP).

Is port 1924 TCP or UDP?

Port 1924 is registered for TCP and UDP.

Is it safe to open port 1924?

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 1924 is open?

On Linux run "ss -ltnup 'sport = :1924'", on macOS "lsof -nP -i :1924", and on Windows "netstat -ano | findstr :1924" to see the local process. From another machine, "nmap -p 1924 <host>" shows whether it is reachable.
