已解决：看来又得再折腾了。ROS5.18升级到5.20后，DDNS用不了了。
本帖最后由 kzyfl 于 2012-9-28 12:26 编辑已解决,半个月都没远程了，现在终于搞成了，不是网卡聚合问题,也不是升级到5.20的问题，是DDNS动态域名自动被删除了，手动添加上去，现在好了。
真郁闷，正常用的二级域名，说删就删，在这里谴责一下。www.changeip.com

脚本有问题.... sffqqq 发表于 2012-9-24 10:04 static/image/common/back.gif
脚本有问题....
5.18的时候可以正常用的,请问一下,哪个地方出现的问题. 问题更难琢磨了.我把版本还原到5.18，还是不行。最近就动过两次ROS，一次是升级到ROS 5.20，另一次是增加一块内网网卡,做双网卡bonding,用的是：balance-xor 模式。不会是内网网卡绑定引起的DDNS不能正常使用吧。 本帖最后由 kzyfl 于 2012-9-28 10:40 编辑

脚本本身应该没问题吧。原来一直用的正常,只是设定了双网卡内网聚合和升级到5.20后才出的问题，现在还原到ROS5。18了。这个DDNS的原理是，在ROS FTP根目录下建创建个记事本文件，ip.changeip.com.txt，如果外线PPPOE接口中的默认端口IP有变化，就更改记事本文件里面的IP值，然后通过脚本使二级域名绑记事要里面的IP，我测试过了，可以正常更新记事本里面的IP，就是不可以正常读取IP。记事本里面的内容为：123.14.58.111<!--IPADDR=123.14.58.111-->
付更新IP日志图： 如果没记错，如果你半年没有登陆changeip网站，就会删除你帐户下的域名（免费用户），且删除前会有邮件提醒 一般都没有问题，多到changeip.net查查更新记录。现几乎每月都有问题，说1小时恢复有可能要半天。
