ADSL做得BBS，但是由于ADSL是动态IP的问题，所以论坛经常上不上，我我已经根据论坛的帖子设置如下了：

但是段流后他不会自动执行adsl-start这个命令，他现在显示的是
[root@server1 sbin]# No response to 3 echo-requests
Serial link appears to be disconnected.
Connection terminated.
Connect time 75.4 minutes.
Sent 30 bytes, received 25246970 bytes.
pppoe: read (asyncReadFromPPP): Session 247: Input/output error
不晓得如何解决，域名指向的IP他不会自动更新

有人能帮帮忙吗

seablue

我也想知道啊
帮你顶下！

waynewu

建议兄弟你看看接压缩后的说明文件README:
里面有注明:修改/etc/ppp/ip-up  
将/usr/sbin/ez-ipupdate -i ppp0 -h diypark.3322.org -S qdns -u 用户名:密码
加到后面，如果是Redhat要加到“exit 0"之前。
看你很眼熟，是不是RHCE 8月份那一期的？

.......这个你都知道阿,我是文华8月班的,准备这个月考试啦,不过心里还没底,嗨..先考考再说,那个说明档我已经加了,我再去看看,也许路径不对
