03 Check it

Which program uses port 2929, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2929'      # process listening on 2929
sudo lsof -nP -i :2929

macOS

sudo lsof -nP -i :2929

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2929 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2929
netstat -ano | findstr :2929

From another machine

nmap -p 2929 -sV <host>
sudo nmap -sU -p 2929 <host>
nc -zv <host> 2929

Block it in the firewall

sudo ufw deny 2929/tcp                                         # Linux (ufw)
