在 ubuntu 中設置網路管理器 dns

  • January 10, 2015

我有 Ubuntu 14.10。當我在工作時,我可以毫無問題地瀏覽網際網路。現在我在家,我可以連接,但我無法瀏覽網頁。

一些資訊:

ifconfig 的輸出:

marcosh@marcoshstudio:~$ ifconfig
lo        Link encap:Local Loopback  
         inet addr:127.0.0.1  Mask:255.0.0.0
         inet6 addr: ::1/128 Scope:Host

         RX bytes:24638 (24.6 KB)  TX bytes:24638 (24.6 KB)

         RX bytes:87556 (87.5 KB)  TX bytes:234860 (234.8 KB)

我正在使用網路管理器,這是 nm-tool 的輸出:

marcosh@marcoshstudio:~$ nm-tool

   Gateway:         192.168.1.254

   DNS:             192.168.1.254
   DNS:             8.8.8.8 

我擔心文件 /etc/resolv.conf 中的設置會干擾:

marcosh@marcoshstudio:~$ cat /etc/resolv.conf
domain mva.local
search mva.local
nameserver 192.168.242.1

那可能嗎?

我知道(因為我曾經這樣做過)如果我刪除並重新安裝網路管理器,我將能夠在家中瀏覽,但不能在辦公室瀏覽。我怎樣才能避免這種情況並一勞永逸地解決我的問題?

最終我解決了它

sudo dpkg-reconfigure resolvconf
