01 Security

Is port 9007 dangerous?

We have no specific security note for port 9007. 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 9007, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9007'      # process listening on 9007
sudo lsof -nP -i :9007

macOS

sudo lsof -nP -i :9007

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9007 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9007
netstat -ano | findstr :9007

From another machine

nmap -p 9007 -sV <host>
sudo nmap -sU -p 9007 <host>
nc -zv <host> 9007

Block it in the firewall

sudo ufw deny 9007/udp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 9007" -Direction Inbound -LocalPort 9007 -Protocol UDP -Action Block  # Windows
04 FAQ
What is port 9007 used for?

Port 9007 is assigned by IANA to ogs-client (Open Grid Services Client).

Is port 9007 TCP or UDP?

Port 9007 is registered for UDP.

Is it safe to open port 9007?

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 9007 is open?

On Linux run "ss -ltnup 'sport = :9007'", on macOS "lsof -nP -i :9007", and on Windows "netstat -ano | findstr :9007" to see the local process. From another machine, "nmap -p 9007 <host>" shows whether it is reachable.
