sudo tcpdump -i ethernet_baglanti_adi örnek: "wlan veya eth0 gibi... komutu terminalden verdikten sonra firefox ile internette gezinin.
Bilgi: tcpdump nedir?

[Good False]

bende yok.

[localhost]

bir siteye gir ve biraz bekle...

[mete13]

ben denedim nasıl durduracağız şimdi bir sürü yazı akıyor ama anlamadım

[localhost]

ctrl+c ile durdurabilirsin. Önemli olan sendede  europium.canonical.com.ntp baglanti veya icinde canoncial.com.ntp gibi bir ibare geciyormu ? Burada paketleri izliyorsun. Hatta bunlarin icine bile bakabilirsin

[mete13]

inceledim ama o yazdığın europium.canonical.com.ntp göremedim. yanlız benim açık sekmeler ve rapidshare ve modem adresi var. yanlız rapidshare başında rs38l3.rapidshare.com var

[localhost]

Ciktilarda "canoncial" ibaresi yokmu yani ? Yada sen ciktilari mümkünse yapistir. IP adreslerini nasil degistiripte pastelerim diye düsünüyorsan. Ciktilari kopyala. gedit ac sonra icine yapistir. Sag üst kösede degistir sekmesine tikla ip adreslerini gir ve ikinci satira XXX doldur sonra hepsini degistir de
