Is port 7411 dangerous?

We have no specific security note for port 7411. 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 7411, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7411'      # process listening on 7411
sudo lsof -nP -i :7411

macOS

sudo lsof -nP -i :7411

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7411 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7411
netstat -ano | findstr :7411

From another machine

nmap -p 7411 -sV <host>
sudo nmap -sU -p 7411 <host>
nc -zv <host> 7411

Block it in the firewall

sudo ufw deny 7411/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7411" -Direction Inbound -LocalPort 7411 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7411 used for?

Port 7411 is assigned by IANA to daqstream (Streaming of measurement data).

Is port 7411 TCP or UDP?

Port 7411 is registered for TCP and UDP.

Is it safe to open port 7411?

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 7411 is open?

On Linux run "ss -ltnup 'sport = :7411'", on macOS "lsof -nP -i :7411", and on Windows "netstat -ano | findstr :7411" to see the local process. From another machine, "nmap -p 7411 <host>" shows whether it is reachable.
