Frequently asked questions

What is port 2004 used for?

Port 2004 sits in the Web & HTTP Services category. This page lists the registered purpose and the software commonly associated with it; to see what is actually listening on a specific machine, check the process with ss/netstat.

Is port 2004 TCP or UDP?

The registered protocol on this page is TCP. The same number behaves independently on each protocol: TCP may be listening while UDP is idle, so check them separately.

How do I check if port 2004 is in use?

On Linux: sudo ss -tlnp 'sport = :2004' for an exact port match. On macOS: sudo lsof -nP -iTCP:2004 -sTCP:LISTEN. On Windows PowerShell: Get-NetTCPConnection -LocalPort 2004 -State Listen. A listener counts as confirmed only when you can see the bind address and process name; without root/admin you will not see other users' processes.

Is port 2004 secure? Should I open it in my firewall?

A port number has no inherent security — it depends on whether the listening service is correctly configured and whether it needs exposure at all. Keep loopback/internal-only services firewalled; where public access is required, pair it with source restrictions, VPN or authentication.
