01 Security

Is port 8190 dangerous?

We have no specific security note for port 8190. 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 8190, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8190'      # process listening on 8190
sudo lsof -nP -i :8190

macOS

sudo lsof -nP -i :8190

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8190 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8190
netstat -ano | findstr :8190

From another machine

nmap -p 8190 -sV <host>
nc -zv <host> 8190

Block it in the firewall

sudo ufw deny 8190/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8190" -Direction Inbound -LocalPort 8190 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8190 used for?

Port 8190 is assigned by IANA to gcp-rphy (Generic control plane for RPHY).

Is port 8190 TCP or UDP?

Port 8190 is registered for TCP.

Is it safe to open port 8190?

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 8190 is open?

On Linux run "ss -ltnup 'sport = :8190'", on macOS "lsof -nP -i :8190", and on Windows "netstat -ano | findstr :8190" to see the local process. From another machine, "nmap -p 8190 <host>" shows whether it is reachable.
