01 Security

Is port 3519 dangerous?

We have no specific security note for port 3519. 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 3519, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3519'      # process listening on 3519
sudo lsof -nP -i :3519

macOS

sudo lsof -nP -i :3519

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3519 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3519
netstat -ano | findstr :3519

From another machine

nmap -p 3519 -sV <host>
sudo nmap -sU -p 3519 <host>
nc -zv <host> 3519

Block it in the firewall

sudo ufw deny 3519/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3519" -Direction Inbound -LocalPort 3519 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3519 used for?

Port 3519 is assigned by IANA to galileo (Netvion Galileo Port), nvmsgd (Netvion Messenger Port).

Is port 3519 TCP or UDP?

Port 3519 is registered for UDP and TCP.

Is it safe to open port 3519?

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 3519 is open?

On Linux run "ss -ltnup 'sport = :3519'", on macOS "lsof -nP -i :3519", and on Windows "netstat -ano | findstr :3519" to see the local process. From another machine, "nmap -p 3519 <host>" shows whether it is reachable.
