D.O.S: disk operating system?naaaaaa
autore: SosPiro "!SunSetZer0 CreW!"
musica ascoltata: John Lennon (beatles ruLez!)
cibo consumato: tutto quello ke mi passa davanti dal duplo alla polvere della mia camera : )
Allora non penserete ke mi metta a fare una tristissima spiegazione su kos'è un denial of service vero??!?Quella l'hanno già fatta in molti ma tanto la cosa da capire è una sola:elimare i lamer ha un senso ke si credono dei fighi soltanto perkè usano Linux o ,peggio ancora, perchè il loro Windows 9X li protegge dalla gente kattiva.Insomma qui trovate soltanto una serie di d.o.s. ke mi sono sembrati davvero interessanti e ( soprattutto ) funzionanti.
1) Il primo qui sotto killa una porta controllata dal super daemon InetD.
