环境：台式机、Ralink 802.11无线网卡、Ubuntu、wireshark
抓了好久，只抓到了Beacon、Probe Request、Data，其他帧根本都没有！
后来，换成自带无线网卡的笔记本抓，好了。
看来，无线网卡是坑啊。
抓包802.11的坑
Those who seek some sort of a higher purpose or 'universal goal', who don't know what to live for, who moan that they must 'find themselves'. You hear it all around us. That seems to be theofficial bromide of our century. Every book you open. Every drooling self-confession. It seems to be the noble thing to confess. I'd think it would be the most shameful one.
