Is port 3419 dangerous?

We have no specific security note for port 3419. 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 3419, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3419'      # process listening on 3419
sudo lsof -nP -i :3419

macOS

sudo lsof -nP -i :3419

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3419 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3419
netstat -ano | findstr :3419

From another machine

nmap -p 3419 -sV <host>
sudo nmap -sU -p 3419 <host>
nc -zv <host> 3419

Block it in the firewall

sudo ufw deny 3419/tcp                                         # Linux (ufw)
