# Find process using port 7000 sudo lsof -i :7000 # Instantly kill process on port 7000 lsof -ti:7000 | xargs kill -9
Windows (PowerShell & CMD)
# Find PID listening on port 7000 netstat -ano | findstr :7000 # Force kill by PID taskkill /PID <PID_NUMBER> /F
Cross-Platform Node.js One-Liner
# Kill port 7000 via npx npx kill-port 7000 # Or diagnose via Castov CLI npx castov fix "EADDRINUSE :::7000"
Linux Firewall (UFW) & Connectivity Test
# Test if port 7000 is reachable nc -zv localhost 7000 # Allow or deny port 7000 in UFW sudo ufw allow 7000/tcp
