带来一篇CentOS下设置ADSL 拨号上彀

欢迎大家来到仓酷云论坛！上面次要先容一下，在CentOS下令行情况下怎样设置ADSL联网：

1、确保装置了网卡并能一般运转，利用下令检察一下网卡形态：

[root@localhostsimon]#/sbin/ifconfigeth0

2、在体系中不要设置默许路由(网关)，让ADSL拨号后主动取得。

3、检察是不是装置了pppoe软件包。

[root@localhostsimon]#rpm-qa|grepppp0e

没有显现，申明没有装置，体系光盘里会有这个装置包，或往下载一个rpm包，装置一下就OK了。

以下图所示举行装置：

登录/注册后可看大图

4、装置好软件包后，便可入手下手设置ppp0e客户端软件了，我们不用手工往修改设置文件，可使用adsl-setup这个工具举行设置：
