/port-check

Analyze port usage and listening services:

1. List all listening ports: ss -tulpn
2. Check for common service ports (80, 443, 22, etc.)
3. Identify processes using ports: netstat -tulpn | grep Llocal timeEN
4. Check for unexpected listening services
5. Verify Docker container port mappings: docker ps --format "table {{.Names}}\t{{.Ports}}"
6. Check firewall rules: sudo iptables -L -n | grep -E "(ACCEPT|REJECT|DROP)"
7. Identify potential port conflicts

Provide Daniel with:

• List of all listening ports with associated services
• Docker container port mappings
• Any unexpected or unusual port usage
• Potential security concerns (unexpected listening services)
• Port conflicts if any
• Recommendations for port security
