系统为rh9.0,adsl采用pppoe拨号。在系统工具--互联网设置向导中设置好了xDSL的连接为ppp0, 启动的时候就eth0设为不活动,ppp0设为活动。但现在只有少数的网页能打开,多数的网页打不开。浏览器Mozilla 1.21,已经装好了flash5.0的插件。
这是我的adsl-status,上面显示出已经拨号成功。
[root@linuxant root]# adsl-status
Note: You have enabled demand-connection; adsl-status may be inaccurate.
adsl-status: Link is up and running on interface ppp0

现在的情况是我上linuxsir和linuxfans一点问题也没有,如果去sina/163/sohu/chinaren/这些一个都打不开,而且Mozilla还会死。下面是我用ping命令ping出来的结果。
[root@linuxant root]# ping www.sina.com.cn

sina ping得通,但还是打不开
[root@linuxant root]# ping www.linuxsir.cn

linuxfans ping都ping不通,竟然还可以上,好奇怪。
[root@linuxant root]# ping www.163.com
PING www.163.com (202.108.36.155) 56(84) bytes of data.
163 ping不能,也打不开
而这些网站在win下面,或是用带路由的modem上网全部没问题,究竟问题出在那里呢? |
