[GFW BLOG] 我优雅一转身,墙应声而倒。我挥一挥衣袖,不带走一片砖瓦。

又到了周末翻墙的时间了。
使用了一段时间的ssh -D,我终于找回了做人的感觉,自由的空气如此新鲜,信息的绿洲让人神往,流连忘返。
ssh -D如此便利,速度如此流畅,让人印象深刻,但是美中不足的是每次都需要先连接,虽然上次已经分享过我写的一段脚本,实现在Mac上自动翻墙。但上次的脚本比较粗糙,仓促,于是又有了一些新的想法,目标是让翻墙更优雅、潇洒。

上次的版本是0.3,这次改动比较大我把版本设置为0.7,下面简单说一下几点改进:

  1. 自动判断在线状态,如果你还没有上网,是不会执行翻墙程序的;
  2. 自动判断翻墙结果,如果翻墙失败,程序将自动重新尝试;
  3. 自动更新动态IP,你或许在自己的电脑上使用OpenDNS,host网站,或者其他原因需要更新动态IP(近段时间我将发文谈谈Mac上动态IP的问题,请关注);
  4. 自动执行程序,如果你有一些程序,如聊天软件,邮件检查软件等需要在上网的时候开启,也可以设定;
  5. 自动退出程序,如果你有一些程序,如邮件检查程序,Last.fm等,需要在断网的时候关闭,也可以设定;
  6. 设定是否在翻墙成功的时候更新Twitter状态;
  7. 全程语音提示,告诉你程序目前正在干什么,十分Cool;

主要也就7点打改进,新的脚本还包含了错误语音提示,当过程中发生错误,将语音提醒你是什么原因发生错误。
十分建议把脚本设置为开机执行。

程序已经提交到Google Code,并开放源代码:
地址如下:
http://code.google.com/p/flora-ssh-d/
注意!访问Google Code你可能需要先翻墙。

下面贴出源代码,大家粘贴到AppleScript Editor.app里面,修改参数然后执行就可以了。
有不明白的可以邮件或者GTalk联系我,我的邮件/GTalk/MSN/QQ同为:i@leaskh.com
