Tools such as netcat and nmap can be used to do 'bad' things, however unlike your 'tool', they also provide a great many other non destrictive functions. Along with a ridiculous number of period characters you tell us:

"my network flooder..... it creates a packet storm bringing the network to an ultimate standstill"

Hardly what any network administrator would describe as a useful network "testing" tool. Perhaps the first S in the bacronym you mention should also be 'Stupid'.

Running this code on a network you do not own or have appropriate permission to cripple may result in more than an attack from your 'neighbour', you may be fired or prosecuted depending on who you work for and where you live.
