Wireshark（前称Ethereal）是一个网络封包分析软件。网络封包分析软件的功能是撷取网络封包，并尽可能显示出最为详细的网络封包资料。 网络封包分析软件的功能可想像成 "电工技师使用电表来量测电流、电压、电阻" 的工作 - 只是将场景移植到网络上，并将电线替换成网络线。 在过去，网络封包分析软件是非常昂贵，或是专门属于营利用的软件。Ethereal的出现改变了这一切。在GNUGPL通用许可证的保障范围底下，使用者 可以以免费的代价取得软件与其源代码，并拥有针对其源代码修改及客制化的权利。Ethereal是目前全世界最广泛的网络封包分析软件之一。 网络管理员使用Wireshark来检测网络问题，网络安全工程师使用Wireshark来检查资讯安全相关问题，开发者使用Wireshark来 为新的通讯协定除错，普通使用者使用Wireshark来学习网络协定的相关知识当然，有的人也会“居心叵测”的用它来寻找一些敏感信息…… Wireshark不是入侵侦测软件（Intrusion DetectionSoftware,IDS）。对于网络上的异常流量行为，Wireshark不会产生警示或是任何提示。然而，仔细分析 Wireshark撷取的封包能够帮助使用者对于网络行为有更清楚的了解。Wireshark不会对网络封包产生内容的修改，它只会反映出目前流通的封包 资讯。 Wireshark本身也不会送出封包至网络上。
