ubuntu 上使用create-ap 打开AP

先介绍一下 create_ap.

这是一个在linux中创建热点用的脚本, 托管在github中, https://github.com/oblique/create_ap/

在http://git.2f30.org/create_ap/
可以看到ｇｉｔｈｕｂ中这个项目的提交日志。

之前试过ａｐ-hotspot，但是自身的ｕｂｕｎｔｕ版本问题（１４．０４）找不到好的源，
在　apt-get update的时候，一直报错。

后面转投ｃｒｅａｔｅ-ap的怀抱，在网上貌似很多失败的声音。
不过在搜索引擎的帮助下
###cd 到安装目录
####下载源

git clone git://git.2f30.org/create_ap.git

看看以太网（ｅｔｈ）和ｗｉｆｉ的ｉｎｔｅｒｆａｃｅ

具体用法我是看了（https://bbs.archlinux.org/viewtopic.php?id=162895&p=1）
或者你可以看ｒｅａｄｍｅ.mk里具体的Ｕｓａｇｅ

sudo ./create_ap wlan[0,1,2,...] eth[0,1,2,..] MyAccessPoint MyPassPhrase

执行脚本前先把网卡关了
可是我这边一直会报错

Doing cleanup.. done

后面感谢电脑玩家的这篇文章（http://www.07net01.com/linux/2016/01/1130576.html）
后面用如下两个命令，先看看ｒｆｋｉｌｌ的状态，然后设置下ｕｎｂｌｏｃｋ

最后就大功告成了
