To carry out the attack, you would need to find line-of-sight and have good signal strength (between -40 and -80 dBm) to the target AP, and have knowledge of an SUID which is already connected, or try random numbers until you find one which works - most providers have quite a number of subscribers per AP so this should not be hard.

进行攻击，你需要找到的视线，并具有良好的信号强度（在-40和-80 dBm的）美联社的目标，并具有一的SUID知识，已经连接，或者尝试随机数直到您找到一个工作-大多数供应商有不少美联社用户每一个数字，所以这应该不难。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
