5800 5900 vnc port scan?

[ukrodriguez]

mai exista un asemenea lucru care sa mearga?

[stroici]

Aproape orice scanner de porturi "stie" sa ii poti seta pe ce porturi sa scaneze. Daca intrebi daca exista astfel de compuri cu porturile astea deschise pe Interweb, ieri erau vreo 4-5 milioane

[ukrodriguez]

am incercat 3 pagini de google, si nu am facut decat sa ma virusez. am scanat un host pe care era deschis portul (caci il am de mult) si totusi niciun soft nu mi-a detectat asta. sa fie provideru meu de vina? hmmm

a, si tot la subiect am citit putin pe google, cum ca porturile 5800-5900 sunt filtrate nu sunt open, si ca trebuie incercat port sweep, nu port scan.

dude, observ ca sursa este scrisa in java. asa ca am pus mana, am descarcat eclipsa, new project-new class-run

am intordus adresa start si adresa end in consola, dupa care, ce sa vezi, nu-mi face print programelul.

am si cateva warnings in code.

tie iti afiseaza rezultatele?

gresesc eu ceva
