01 Security

Is port 4329 dangerous?

We have no specific security note for port 4329. 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 4329, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4329'      # process listening on 4329
sudo lsof -nP -i :4329

macOS

sudo lsof -nP -i :4329

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4329 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4329
netstat -ano | findstr :4329

From another machine

nmap -p 4329 -sV <host>
nc -zv <host> 4329

Block it in the firewall

sudo ufw deny 4329/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4329" -Direction Inbound -LocalPort 4329 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4329 used for?

Port 4329 is assigned by IANA to publiqare-sync (PubliQare Distributed Environment Synchronisation Engine).

Is port 4329 TCP or UDP?

Port 4329 is registered for TCP.

Is it safe to open port 4329?

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 4329 is open?

On Linux run "ss -ltnup 'sport = :4329'", on macOS "lsof -nP -i :4329", and on Windows "netstat -ano | findstr :4329" to see the local process. From another machine, "nmap -p 4329 <host>" shows whether it is reachable.
