01 Security

Is port 1429 dangerous?

We have no specific security note for port 1429. 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 1429, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1429'      # process listening on 1429
sudo lsof -nP -i :1429

macOS

sudo lsof -nP -i :1429

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1429 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1429
netstat -ano | findstr :1429

From another machine

nmap -p 1429 -sV <host>
sudo nmap -sU -p 1429 <host>
nc -zv <host> 1429

Block it in the firewall

sudo ufw deny 1429/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1429" -Direction Inbound -LocalPort 1429 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1429 used for?

Port 1429 is assigned by IANA to nms (Hypercom NMS).

Is port 1429 TCP or UDP?

Port 1429 is registered for TCP and UDP.

Is it safe to open port 1429?

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 1429 is open?

On Linux run "ss -ltnup 'sport = :1429'", on macOS "lsof -nP -i :1429", and on Windows "netstat -ano | findstr :1429" to see the local process. From another machine, "nmap -p 1429 <host>" shows whether it is reachable.
