我目前在 Eclipse Indigo Service Release 2 上运行 android 模拟器（Android 1.6 api level 4）版本 18，在 Debian 6.0 上使用 ADT 插件 18.0。我在代理地址的大学代理（鱿鱼）后面：http://172.20.0.99:8080没有身份验证。它是一个 eth0 连接，所以没有无线/局域网卡问题。我在环境变量和模拟器选项中都设置了代理。也正如之前的一些帖子中提到的，我提供了 -dns-server 选项。我的模拟器运行如下。

显然它能够正确设置代理和 reslove dns-server。当我在模拟器中打开浏览器并键入主机名时，例如http://google.com它无法连接（网页不可用），但使用直接 IP 地址（173.194.32.32）它能够连接（google.com）。我无法理解出了什么问题。在发布之前我也咨询了以下线程并尝试了各种解决方案但无济于事。我想知道我的桌面浏览器（firefox 12）如何进行 dns-lookup？我还尝试了从租约文件中获取的内部 dns-servers，但结果相同。请进一步指导我。甚至我的桌面浏览器如何解析主机名的信息也将是有益的。我在stackoverflow上咨询了许多有类似问题的线程，但由于声誉的限制，无法粘贴它们的链接。代码形式：

我什至在eclipse中为我的项目输入了正确的运行配置-
-http-proxy http://172.20.0.99:8080 -dns-server 8.8.8.8
但得到了相同的结果。
因为这是我在 stackoverflow 社区的第一篇文章，所以我想尽可能详尽。请告知我帖子中的任何不足之处。提前致以诚挚的感谢。
