Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

WR703N OpenWrt 配置流程

下载安装

访问WR703N在OpenWrt的[Wiki页][wr703n-openwrt]，然后在Flashing一节中找到下载链接：[squashfs-factory.bin][flash.bin]，下载后别忘了[比对md5][md5sum]。^[1]

进入路由器管理界面，出厂配置为http://192.168.1.1，用户名和密码均为admin，然后进入固件更新，选择下载的文件，然后更新。

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

Add RailsAdmin to your Gemfile

do NOT add devise

gem "rails_admin", :git => "git://github.com/sferik/rails_admin.git"
