  • 1.常用的指令

    • 1.過濾出特定protocol的封包

          Filter: tcp

    • 2.過濾出特定protocol及其相依protocol的封包

          Filter: portmap||mount

    • 3.IP + 特定port號

          Filter: ip.addr == <IP> && tcp.port == <Port>

    • 4.Follow TCP/UDP stream

    • 5.Apply as filter

      • 若想過濾出與特定封包類似的封包, 對封包按右鍵選擇"Apply as filter", 可以自動產生相對應的運算式及過濾出相對應的封包.

  • 2.封包解析

    • ex 1. ip(來源或目的地)為192.168.1.5, 並監聽DNS port

    • 解析http封包

      • 1.Frame

      • 2.Ethernet

      • 3.IP protocol

      • 4.Transport protocol

      • 5.HTTP protocol
