03 Check it

Which program uses port 2923, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2923'      # process listening on 2923
sudo lsof -nP -i :2923

macOS

sudo lsof -nP -i :2923

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2923 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2923
netstat -ano | findstr :2923

From another machine

nmap -p 2923 -sV <host>
sudo nmap -sU -p 2923 <host>
nc -zv <host> 2923

Block it in the firewall

sudo ufw deny 2923/tcp                                         # Linux (ufw)
