[注意]adsl和lan开机自动拨号出问题的暂时解决方法。（pppoe）

[blackwolf]

呵呵, 我都是把eth的IP设为手动, 在本机架一个DNS 缓存服务器.
编辑/etc/sysconfig/network-script/ppp0, 把一个peerdns 改为NO.
编辑/etc/resolv.conf,只放本机的IP.
很好, dns解析也很快.

每当你访问网上邻居的话，域名解释首先会往外跑，在外头巨大的互联网找不到192.168.1.xx这类地址之后才会轮到后面的dns，这样的后果就是网络邻居要等好久才能看到电脑。我是因为这个原因才说加上192.168.1.1的，给网络造成一点可有可无的负担，总比网络邻居半天不出来好点。

向主、辅名字服务器发出的DNS查询请求几乎是同时发出的，而不是说当主名字服务器查询失败后再向辅名字服务器发请求。

请问谁知道在ubuntu下设置双ADSL或三ADSL拨号呢?

[5451vs5451]

是所有的ADSL都拨一个号，还是每个ADSL拨不同的号？

[liumailong]

多个不同的PPPOE同时连接，怎么实现呀！

[arsui]

搂住的方法好像不行～
ps 我的拨号的dns应该是动态的把～
