01 Security

Is port 1224 dangerous?

We have no specific security note for port 1224. 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 1224, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1224'      # process listening on 1224
sudo lsof -nP -i :1224

macOS

sudo lsof -nP -i :1224

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1224 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1224
netstat -ano | findstr :1224

From another machine

nmap -p 1224 -sV <host>
sudo nmap -sU -p 1224 <host>
nc -zv <host> 1224

Block it in the firewall

sudo ufw deny 1224/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1224" -Direction Inbound -LocalPort 1224 -Protocol TCP -Action Block  # Windows

What is port 1224 used for?

Port 1224 is assigned by IANA to vpnz (VPNz).

Is port 1224 TCP or UDP?

Port 1224 is registered for TCP and UDP.

Is it safe to open port 1224?

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 1224 is open?

On Linux run "ss -ltnup 'sport = :1224'", on macOS "lsof -nP -i :1224", and on Windows "netstat -ano | findstr :1224" to see the local process. From another machine, "nmap -p 1224 <host>" shows whether it is reachable.
