| Ubuntu 网速慢，主要是把时间浪费在域名解析上。我们可以用dnsmasq解决这问题。 具体如下： 安装dnsmasq 命令: sudo apt-get install dnsmasq 编辑dnsmasq的配置文件 命令: sudo gedit /etc/dnsmasq.conf 找到下面这一项 #resolv-file= 用下面的一条语句替换 resolv-file=/etc/resolv.dnsmasq.conf 确保你没有更改过/etc/resolv.conf文件，如果改过，恢复原状 然后执行命令 sudo cp /etc/resolv.conf /etc/resolv.dnsmasq.conf 然后编辑resolv.conf 命令;sudo gedit /etc/resolv.conf 将其中的域名服务器全部去掉，加入以下这行 nameserver 127.0.0.1 如果用路由上网也可以加上路由的地址 保存，退出 执行以下命令 sudo gedit /etc/ppp/peers/wvdial 在 usepeerdns 前面增加 ＃ ，也就是把这条语句覆盖掉。 以防，resolv.conf的设置被pppoe覆盖。 重启电脑。不重启，你会发现无法解析域名。所以一定要重启电脑，来达到重新启动dnsmasq的目的。 重启后， 你会发现解析速度比以前快了N个数量级。 选择最近的源也可以进一步提高网速 在终端中输入； $sudo gedit /etc/apt/sources.list 清空后把源地址复制到这里面 $sudo apt-get update 第一个update完之后接着 $sudo apt-get upgrade PS;源地址 Archive.ubuntu.com 更新服务器(欧洲)： deb dapper
