01 Security

Is port 7429 dangerous?

We have no specific security note for port 7429. 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 7429, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7429'      # process listening on 7429
sudo lsof -nP -i :7429

macOS

sudo lsof -nP -i :7429

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7429 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7429
netstat -ano | findstr :7429

From another machine

nmap -p 7429 -sV <host>
sudo nmap -sU -p 7429 <host>
nc -zv <host> 7429

Block it in the firewall

sudo ufw deny 7429/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7429" -Direction Inbound -LocalPort 7429 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7429 used for?

Port 7429 is assigned by IANA to opi-sock (OpenView DM rqt communication).

Is port 7429 TCP or UDP?

Port 7429 is registered for TCP and UDP.

Is it safe to open port 7429?

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 7429 is open?

On Linux run "ss -ltnup 'sport = :7429'", on macOS "lsof -nP -i :7429", and on Windows "netstat -ano | findstr :7429" to see the local process. From another machine, "nmap -p 7429 <host>" shows whether it is reachable.
