[问题]ADSL拨号上网失败！

Johan Tam · **发表于 :** 2007-06-06 21:15

刚开始的时候用pppoeconf配置ADSL拨号，成功地连接上internet.
后来先后试了Ubuntu-firewall, lokkit, Firestarter几个防火墙，然后稀里糊涂的突然就上不了网了，任凭我折腾还是ping不通任何ip。于是我又用network-admin配置了一下，修改了/etc/interfaces，仍然未果。现在上网都得跑XP，双系统来回启动切换的，我要受不了了。
下面是我拨号后的响应信息：
johan@johan-desktop:~$ plog

Jun 5 18:50:21 johan-desktop pppd[6055]: pppd 2.4.4 started by root, uid 0

Jun 5 18:50:27 johan-desktop pppd[6055]: Connection terminated.
Jun 5 18:50:27 johan-desktop pppd[6055]: Modem hangup

还有部分系统日志见附件。
焦急期待帮助中！请大家踊跃赐教，不胜感激：）

每次重启后右上角网络连接标志不停地转动，显示正在请求IP。
如图：

这个时候运行route 指令得到的路由表为空！

pin is null是否之用户名为空？(pin好像是用户身份)
请问问题的关键是？
在这之前还ifconfig返回3个接口：eth0, eth0:avahi 和lo ,参考了一些信息后我把产生eth0:avahi的avahi-autoipd给卸载了。
请问问题的关键是？如何解决？相当折磨人啊。。。。

跟我一样。也是装了好几个防火墙后就在也登录不了网络了。
重装了。现在好了很多。

我是关了防火墙能上网，不关就上不了！！
