01 Security

Is port 4404 dangerous?

We have no specific security note for port 4404. 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 4404, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4404'      # process listening on 4404
sudo lsof -nP -i :4404

macOS

sudo lsof -nP -i :4404

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4404 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4404
netstat -ano | findstr :4404

From another machine

nmap -p 4404 -sV <host>
sudo nmap -sU -p 4404 <host>
nc -zv <host> 4404

Block it in the firewall

sudo ufw deny 4404/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4404" -Direction Inbound -LocalPort 4404 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4404 used for?

Port 4404 is assigned by IANA to ds-admin (ASIGRA Televaulting DS-System Monitoring/Management).

Is port 4404 TCP or UDP?

Port 4404 is registered for TCP and UDP.

Is it safe to open port 4404?

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 4404 is open?

On Linux run "ss -ltnup 'sport = :4404'", on macOS "lsof -nP -i :4404", and on Windows "netstat -ano | findstr :4404" to see the local process. From another machine, "nmap -p 4404 <host>" shows whether it is reachable.
