01 Security

Is port 4429 dangerous?

We have no specific security note for port 4429. 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 4429, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4429'      # process listening on 4429
sudo lsof -nP -i :4429

macOS

sudo lsof -nP -i :4429

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4429 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4429
netstat -ano | findstr :4429

From another machine

nmap -p 4429 -sV <host>
nc -zv <host> 4429

Block it in the firewall

sudo ufw deny 4429/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4429" -Direction Inbound -LocalPort 4429 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4429 used for?

Port 4429 is assigned by IANA to omviagent (OMV Investigation Agent-Server).

Is port 4429 TCP or UDP?

Port 4429 is registered for TCP.

Is it safe to open port 4429?

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 4429 is open?

On Linux run "ss -ltnup 'sport = :4429'", on macOS "lsof -nP -i :4429", and on Windows "netstat -ano | findstr :4429" to see the local process. From another machine, "nmap -p 4429 <host>" shows whether it is reachable.
