网络中的数据包嗅探器?


0

我在MAC访问列表中找到了被阻止的MAC地址(00-1A-B6-00-64-00),并且禁用了MAC过滤后,在Wireshark中显示了此详细信息:

Frame 112389: 342 bytes on wire (2736 bits), 342 bytes captured (2736 bits) on interface 0
Ethernet II, Src: TexasIns_00:64:00 (00:1a:b6:00:64:00), Dst: Broadcast (ff:ff:ff:ff:ff:ff)

我搜索后TexasIns_00发现该设备是USB数据包嗅探器。

你认为这是真的吗?


使用此信息,您只能说出它可能是具有德州仪器(TI)生产的NIC的设备。您是如何得出结论的,这是一个USB设备?

实际上,TexasIns只是Wireshark对所谓的OUI(组织唯一标识符)的解释,它是每个制造商唯一的MAC地址的前三个字节...在这种情况下,这是德州仪器(TI)的OUI(00:1a:b6)所以没有什么好担心的。
