ubuntu 14.04中的DNS问题

Question

我面临DNS解决问题，有时在我的Ubuntu14.04.2LTS信任。

我已将我的系统配置为网络管理器，以处理静态IP分配。我也尝试通过更改DNS服务器地址，但当这个问题发生时，我不能通过URL访问任何网站，但我只能通过IP访问。

在这个问题上，我试过

• 停止dnsmasq服务
• 去强的松
• 重新启动网络服务
• 重新启动网络管理器
• 查找像google，yahoo这样的域名

转储脚本

输出

我不能通过做这些事情来解决问题。但唯一的解决办法是重新启动我的电脑。

请帮助我，因为它完全卡住了我的全部工作，因为重新启动系统和失去连接的任何时候。

你的帮助将不胜感激。

Answer 1

我遵循了以下步骤，我的问题解决了。

• 删除dnsmasq: apt-获取删除--清除dnsmasq
• 通过在dns=dnsmasq中添加#来注释掉/etc/NetworkManager/NetworkManager.conf。
• 注释掉本地DNS地址。
• 在prepend domain-name-servers 127.0.0.1;中添加#注释/etc/dhcp/dhclient.conf
• 更新resolvconf：-u解析
• 重新启动network-manager或重新启动系统:服务网络管理器重新启动

Answer 2

尝尝这个

在/etc/NetworkManager/NetworkManager.conf中注释掉行dns=dnsmasq

sudo nano /etc/NetworkManager/NetworkManager.conf

[main]
plugins=ifupdown,keyfile,ofono
#dns=dnsmasq

并重新启动NetworkManager服务。

sudo restart network-manager

然后

sudo rm -f /etc/resolv.conf  # Delete the symbolic link

和

sudo nano /etc/resolv.conf

    # Content of static resolv.conf
    nameserver 8.8.4.4
    nameserver 8.8.8.8

在这种情况下，您的pc将在没有dnsmasq的情况下解析/etc/resolv.conf中的dns服务器的名称。
