01 Security

Is port 7019 dangerous?

We have no specific security note for port 7019. 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 7019, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7019'      # process listening on 7019
sudo lsof -nP -i :7019

macOS

sudo lsof -nP -i :7019

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7019 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7019
netstat -ano | findstr :7019

From another machine

nmap -p 7019 -sV <host>
sudo nmap -sU -p 7019 <host>
nc -zv <host> 7019

Block it in the firewall

sudo ufw deny 7019/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7019" -Direction Inbound -LocalPort 7019 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7019 used for?

Port 7019 is assigned by IANA to doceri-ctl (doceri drawing service control), doceri-view (doceri drawing service screen view).

Is port 7019 TCP or UDP?

Port 7019 is registered for TCP and UDP.

Is it safe to open port 7019?

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 7019 is open?

On Linux run "ss -ltnup 'sport = :7019'", on macOS "lsof -nP -i :7019", and on Windows "netstat -ano | findstr :7019" to see the local process. From another machine, "nmap -p 7019 <host>" shows whether it is reachable.
