DD-WRT 自动翻墙、自动分流

Posted on April 22, 2012 by Richard Huang

前天家里的 ADSL modem 坏了，一个杂牌用了五年，嗯，还算不错。趁着记忆还没被别的内容取代，记下配置 DD-WRT 通过 OpenVPN 自动翻墙、（墙）内外分流的过程。当然，你也可以用 PPTP、L2TP/IPSec，但我只喜欢 OpenVPN。 第一步，确保你的无线路由器刷了有 openvpn 和 jffs 功能的 DD-WRT 固件包（参考：如何选择适合你的无线路由器的 DD-WRT 固件包）。注意，并非越新的版本就越好，比如最近 eko 编译的两个新版 svn17990（2011年12月8日） 和 svn18946（2012年4月7日） 的 jffs 都存在问题，所以我还是在使用2011年5月18日发布的 svn17084 版本。 第二步，做好 DD-WRT 的基本配置，包括 PPPoE、Router Name、NTP、wireless 等。 第三步，启用 jffs 第四步，配置自动翻墙、（墙）内外分流，即，只有被墙了的地址才走 VPN，其他仍走 ISP … Continue reading →

Publish Packages on PPA

Posted on April 20, 2012 by Richard Huang

如果你希望把你制作的 deb 包分享给社区，你需要自己设立一个 repository，对大多数人来说，这有点太麻烦了。Ubuntu 提供了一项免费服务 PPA，你可以把自己的包上传至 PPA 上，分享给别人。 1. 注册一个 LaunchPad 帐号，比如帐号为 lpfoobar 2. 注册完毕、登录后，在你的 LaunchPad 页面上注册你的 GPG Key 和 SSH 公钥。 3. 点击 Create a new PPA，创建一个 PPA，比如名称为 myppa 4. 编译 deb 包，不能生成 binary 包，因为 PPA 只接受源码包，所以使用以下指令编译制作： $ dpkg-buildpackage … Continue reading →

Customize CyanogenMod ROM

Posted on January 2, 2012 by Richard Huang

不知道还有多少人在坚持使用早期的 Android 设备，比如 HTC Dream (G1)、Magic (G2) 等。上个月某天午饭时，一个同事说她最近入手了 Sensation (G14)，因为原先的那台 Hero (G3) 实在太慢了。嗯，想起了 Richard Jones 说的——Android is the new Windows. 多数情况下，用户不会去管操作系统，于是太多的硬件资源被不必要地占用了，而且还带来不稳定性。但 Android 的开放性使得用户可以对其进行裁减/定制，最原始的做法是直接从源码开始，不过这太麻烦了，另一种做法是修改已经存在的 ROM 安装包。 我依然在使用 G2，已经两年半了，机器里跑的是基于 CM 6.1.0 裁减之后的版本，速度和稳定性都是能接受的。下表（Table 1）列出了修改细节： Table 1. CyanogenMod ROM 程序包 用途 改变 AccountAndSyncSettings.apk 账户同步设置 … Continue reading →
