1.Wireshark介紹

Wireshark 是一個開源的網(wǎng)絡協(xié)議分析工具，它能夠捕獲和分析網(wǎng)絡數(shù)據(jù)包，提供深入的網(wǎng)絡故障排除、網(wǎng)絡性能優(yōu)化和安全審計等功能。它支持跨多個操作系統(tǒng)，包括 Windows、macOS 和 Linux。

2.Wireshark主要使用方法

• 捕獲數(shù)據(jù)包：

????????打開 Wireshark，選擇要捕獲數(shù)據(jù)包的網(wǎng)絡接口。您可以選擇物理網(wǎng)卡或虛擬接口。
點擊“開始”按鈕開始捕獲數(shù)據(jù)包。
????????Wireshark 將開始監(jiān)聽選定的接口，并顯示捕獲到的數(shù)據(jù)包。

• 分析數(shù)據(jù)包：

????????捕獲到的數(shù)據(jù)包將以列表形式顯示在 Wireshark 界面上。您可以查看每個數(shù)據(jù)包的詳細信息，如源地址、目標地址、協(xié)議類型等。
????????Wireshark 還提供了過濾器功能，使您可以根據(jù)特定的協(xié)議、源/目標地址、端口等條件來篩選和查找感興趣的數(shù)據(jù)包。
????????可以查看每個數(shù)據(jù)包的原始數(shù)據(jù)以及解析后的協(xié)議信息，以深入了解網(wǎng)絡通信過程。

• 分析工具和功能：

????????Wireshark 提供了一系列強大的分析工具，如統(tǒng)計信息、流量圖表、協(xié)議層次結(jié)構(gòu)圖等，以幫助您分析和診斷網(wǎng)絡問題。
????????您可以使用統(tǒng)計功能來獲取有關(guān)數(shù)據(jù)包數(shù)量、協(xié)議使用情況、流量分布等方面的信息。
Wireshark 還支持導出數(shù)據(jù)包以供進一步分析或與他人共享。

3.CentOS 圖形化Wireshark快速安裝

• 安裝Wireshark

????????如果直接安裝wireshark，則不包含圖形化界面，可以在命令行執(zhí)行tshark來使用。如需圖形化界面，選擇包含gnome的版本安裝。
