01 Security

Is port 19007 dangerous?

We have no specific security note for port 19007. 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 19007, and is it reachable?

Linux

sudo ss -ltnup 'sport = :19007'      # process listening on 19007
sudo lsof -nP -i :19007

macOS

sudo lsof -nP -i :19007

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 19007 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 19007
netstat -ano | findstr :19007

From another machine

nmap -p 19007 -sV <host>
sudo nmap -sU -p 19007 <host>
nc -zv <host> 19007

Block it in the firewall

sudo ufw deny 19007/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 19007" -Direction Inbound -LocalPort 19007 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 19007 used for?

Port 19007 is assigned by IANA to scintilla (Scintilla protocol for device services).

Is port 19007 TCP or UDP?

Port 19007 is registered for TCP and UDP.

Is it safe to open port 19007?

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 19007 is open?

On Linux run "ss -ltnup 'sport = :19007'", on macOS "lsof -nP -i :19007", and on Windows "netstat -ano | findstr :19007" to see the local process. From another machine, "nmap -p 19007 <host>" shows whether it is reachable.
