这个程序主要是用来在将PPP的数据包映射到Ethernet后，没有Ethernet头，所以Ethereal解码不正确。但是Sniffer Pro的HIS或者SYN格式可以，需要将原来的Ethereal的数据包重新解码，再封装为Sniffer的格式。然后就可以用Ethereal打开，分析了。-This procedure is primarily used in the PPP packet is mapped to the Ethernet, not Ethernet header, so Ethereal decode incorrect. Sniffer Pro, however the HIS or SYN format can require the original re-Ethereal packet decoder, and then package for Sniffer format. Can then be opened with Ethereal analyzed.
