01 Security

Is port 19000 dangerous?

We have no specific security note for port 19000. 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 19000, and is it reachable?

Linux

sudo ss -ltnup 'sport = :19000'      # process listening on 19000
sudo lsof -nP -i :19000

macOS

sudo lsof -nP -i :19000

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 19000 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 19000
netstat -ano | findstr :19000

From another machine

nmap -p 19000 -sV <host>
sudo nmap -sU -p 19000 <host>
nc -zv <host> 19000

Block it in the firewall

sudo ufw deny 19000/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 19000" -Direction Inbound -LocalPort 19000 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 19000 used for?

Port 19000 is assigned by IANA to igrid (iGrid Server).

Is port 19000 TCP or UDP?

Port 19000 is registered for TCP and UDP.

Is it safe to open port 19000?

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 19000 is open?

On Linux run "ss -ltnup 'sport = :19000'", on macOS "lsof -nP -i :19000", and on Windows "netstat -ano | findstr :19000" to see the local process. From another machine, "nmap -p 19000 <host>" shows whether it is reachable.
