01 Security

Is port 8004 dangerous?

We have no specific security note for port 8004. 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 8004, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8004'      # process listening on 8004
sudo lsof -nP -i :8004

macOS

sudo lsof -nP -i :8004

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8004 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8004
netstat -ano | findstr :8004

From another machine

nmap -p 8004 -sV <host>
nc -zv <host> 8004

Block it in the firewall

sudo ufw deny 8004/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8004" -Direction Inbound -LocalPort 8004 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8004 used for?

Port 8004 is assigned by IANA to p2pevolvenet (Opensource Evolv Enterprise Platform P2P Network Node Connection Protocol).

Is port 8004 TCP or UDP?

Port 8004 is registered for TCP.

Is it safe to open port 8004?

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 8004 is open?

On Linux run "ss -ltnup 'sport = :8004'", on macOS "lsof -nP -i :8004", and on Windows "netstat -ano | findstr :8004" to see the local process. From another machine, "nmap -p 8004 <host>" shows whether it is reachable.
