Which program uses port 469, and is it reachable?
Linux
sudo ss -ltnup 'sport = :469' # process listening on 469
sudo lsof -nP -i :469macOS
sudo lsof -nP -i :469
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 469 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 469 netstat -ano | findstr :469
From another machine
nmap -p 469 -sV <host> sudo nmap -sU -p 469 <host> nc -zv <host> 469
Block it in the firewall

What is port 469 used for?
Port 469 is assigned by IANA to rcp (Radio Control Protocol).
Is port 469 TCP or UDP?
Port 469 is registered for TCP and UDP.
Is it safe to open port 469?
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. Require authentication on cameras and media servers.
How do I check if port 469 is open?
On Linux run "ss -ltnup 'sport = :469'", on macOS "lsof -nP -i :469", and on Windows "netstat -ano | findstr :469" to see the local process. From another machine, "nmap -p 469 <host>" shows whether it is reachable.
