[debian-users:57951] ブラウザからネット接続できない

[owner738@xxxxxxxxxxx]

お世話になります。

3種類のブラウザ、Epiphany, Iceweasel, Chromium をインストールし、それぞれから、
http://www.debian.org を見に行ったのですが、全てエラーで表示されません。
nslookup, ping は、通じています。
尚、3ブラウザとも、file:///～ 等、ローカルファイルは表示できました。
考えられる原因がございましたら、お教え頂けますと幸いです。


■Epiphany のエラー表示

Unable to load page

Problem occurred while loading the URL http://www.debian.org/

Cannot resolve hostname


■Iceweasel のエラー表示

Server not found

Iceweasel can't find the server at www.debian.org.

 * Check the address for typing errors such as ww.example.com instead
   of www.example.com

 * If you are unable to load any pages, check your computer's network
   connection.

 * If your computer or network is protected by a firewall or proxy, make
   suure that Iceweasel is permitted to access the Web.



■Chromium のエラー表示

This webpage is not available.

The webpage at http://www.debian.org/ might be temporarily down
or it may have moved permanently to a new web address.

Here are some suggestions:
   * Reload this web page later.
