Bila memakai switch-hub (bukan 'smart-hub' yg bisa dikonfigurasi lagi), tentu packet broadcast bisa bocor ke mana2. Misalnya di LAN saya, pada host ber-IP 192.168.0.1 (bukan gateway): [EMAIL PROTECTED] tgz]# tethereal arp Capturing on eth0 0.000555 Dell_Com_21:49:23 -> Broadcast ARP Who has 192.168.0.3?

Tell 192.168.0.3 Kalo sniffer, coba gunakan ettercap: "Ettercap is a multipurpose sniffer/interceptor/logger for switched LAN", http://ettercap.sourceforge.net/. Tentu bukan sekedar security jaringan perlu banyak interface, tapi memang kalo selayaknya scr fisik pisah, ya lakukan. Bandwidth itu mahal, jadi ketimbang ngantri di 1 interface, khan lebih baik dipecah2. Belum lagi protokol2 sejenis SMB yg broadcast mania. :) Tertanda, Oguds [36856104] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
