01 Security

Is port 7030 dangerous?

We have no specific security note for port 7030. 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 7030, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7030'      # process listening on 7030
sudo lsof -nP -i :7030

macOS

sudo lsof -nP -i :7030

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7030 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7030
netstat -ano | findstr :7030

From another machine

nmap -p 7030 -sV <host>
sudo nmap -sU -p 7030 <host>
nc -zv <host> 7030

Block it in the firewall

sudo ufw deny 7030/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7030" -Direction Inbound -LocalPort 7030 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7030 used for?

Port 7030 is assigned by IANA to op-probe (ObjectPlanet probe).

Is port 7030 TCP or UDP?

Port 7030 is registered for TCP and UDP.

Is it safe to open port 7030?

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 7030 is open?

On Linux run "ss -ltnup 'sport = :7030'", on macOS "lsof -nP -i :7030", and on Windows "netstat -ano | findstr :7030" to see the local process. From another machine, "nmap -p 7030 <host>" shows whether it is reachable.
