ros 5.16 DNS无法解析
本帖最后由 寒雨孤夜 于 2012-6-9 16:02 编辑这两天装了个ROS 5.16 玩，全部都设置完了后出现了个奇怪的问题，就是ROS ping 外面的话DNS无法解析，而我的DNS也已经设置了。如下图，想知道问题出在哪，有知道的朋友告诉一下。
如上图中，ping 61.135.169.105 这个是百度解析后的地址，能PING通，但是直接ping www.baidu.com，就提示DNS无响应。 我们这边的DNS都禁止PING的，所以直接PING DNS是ping 不通的。
兄弟洛阳，周口这边的？？？ 呵呵，河南的DNS，一看就知是吧。。 pppoe-out里
Add Default Route打勾 尝试一下其他域名或换DNS!

ping任何网站都是DNS无响应的，这个DNS，在我内网的其它电脑上就很正常，可以用的。 顶了！！！！！！！！！ 我刚升级到最新的5.17版，没有出现你所说的问题 What's new in 5.17 (2012-May-28 12:34):

*) webfig - make QuickSet scan list work in Firefox v12;
*) webfig - fixed problem in QuickSet when changing country or channel-width in AP
mode would enable NV2 protocol;

唉，我总算找到原因了，是我自己的防火墙把53端口给屏了。。。谢谢楼上朋友热心帮忙。 本帖最后由 芝麻 于 2012-6-12 17:14 编辑
