01 Security

Is port 2007 dangerous?

We have no specific security note for port 2007. 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 2007, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2007'      # process listening on 2007
sudo lsof -nP -i :2007

macOS

sudo lsof -nP -i :2007

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2007 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2007
netstat -ano | findstr :2007

From another machine

nmap -p 2007 -sV <host>
sudo nmap -sU -p 2007 <host>
nc -zv <host> 2007

Block it in the firewall

sudo ufw deny 2007/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2007" -Direction Inbound -LocalPort 2007 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2007 used for?

Port 2007 is assigned by IANA to dectalk (), raid-am ().

Is port 2007 TCP or UDP?

Port 2007 is registered for TCP and UDP.

Is it safe to open port 2007?

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 2007 is open?

On Linux run "ss -ltnup 'sport = :2007'", on macOS "lsof -nP -i :2007", and on Windows "netstat -ano | findstr :2007" to see the local process. From another machine, "nmap -p 2007 <host>" shows whether it is reachable.
