Ntop 3.3 安裝步驟

建置Ntop的目的: 此工具主要在依IP address & TCP/UDP port來Monitor網路流量狀況，可以快速發現網路變慢的問題點在哪？是網路管理者必備工具，而且…它不用花錢。

設置點：看你要Monitor哪裡的封包，通常設置於LAN <--> Internet之間，或是分公司<-->分公司之間，還可以在Core switch上視狀況機動將某個port的流量導入作監控，非常方便。

使用版本: Ntop 3.3
作業系統：Linux Fedora core 8 (需兩張網卡，Monitor & Management)

安裝步驟：

再到Core switch(Cisco 4510 switch)將封包導至Ntop Server 的Monitor port:
3/1 PROXY
3/2 Firewall
3/48 NTOP
monitor session 1 source interface Gi3/1 , Gi3/2
monitor session 1 destination interface Gi3/48
