01 Security

Is port 10004 dangerous?

We have no specific security note for port 10004. 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 10004, and is it reachable?

Linux

sudo ss -ltnup 'sport = :10004'      # process listening on 10004
sudo lsof -nP -i :10004

macOS

sudo lsof -nP -i :10004

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 10004 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 10004
netstat -ano | findstr :10004

From another machine

nmap -p 10004 -sV <host>
nc -zv <host> 10004

Block it in the firewall

sudo ufw deny 10004/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 10004" -Direction Inbound -LocalPort 10004 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 10004 used for?

Port 10004 is assigned by IANA to emcrmirccd (EMC Replication Manager Client).

Is port 10004 TCP or UDP?

Port 10004 is registered for TCP.

Is it safe to open port 10004?

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 10004 is open?

On Linux run "ss -ltnup 'sport = :10004'", on macOS "lsof -nP -i :10004", and on Windows "netstat -ano | findstr :10004" to see the local process. From another machine, "nmap -p 10004 <host>" shows whether it is reachable.
