谢了先！
我先去抓个包看看。

那是不是SDM就连不上了？？？
我的经验分享，如转贴请注明作者：iamxiaop和本站网址：http://www.netemu.cn/bbs/，谢谢！我折腾了一整天了，饭都没有心思吃，希望我的摸索能为黑暗中挣扎的人们指引前进的道路。
使用环境：英文vista操作系统，HP 6710B笔记本，千兆网卡，悉尼Lane Cove一陋室里。
我的不堪回首的痛苦经历， 经过彷徨，失望，绝望的挣扎之后，终于光明一片。
先碰到的问题是：dynamips不能获得网卡参数，总是提示lbcap和winpcap没有安装，搜索网上各种海量信息进行筛选和分析，发现 winpcap安装后，会产生一个NPF的服务，但是不知为什么vista操作系统缺省是禁用这个服务的，于是在注册表中将之打开，问题解决，可以获得网卡参数。哈哈哈！（还有一个办法是论坛上有朋友说安装ethereal，在安装过程中选择开启NPF服务。
Q-18: Is it possible to start WinPcap automatically when the system boots?
A: You can change the start settings of the NPF service to "automatic" or "system". A way to do this is changing the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NPF\Start from 0x3 (SERVICE_DEMAND_START) to 0x2 (SERVICE_AUTO_START) or 0x1 (SERVICE_SYSTEM_START). This works only in Windows NTx.
短暂的快乐迎来的是更大的痛苦，dynamips的7200路由器和本机网卡接的网关互相ping通，本机网卡和这个网关也能互相ping通。但是本机网卡和dynamips的7200路由器就是死活不通。
debug的信息显示7200收到的数据有校验和错误。
再网上又搜索海量信息，进行筛选和分析，发现有可能是网卡的配置问题，我把网卡设置成100M全双工，还是不行，再把网卡的tcp/udp checksum offload设置成disable，哈哈哈！问题解决啦！
注意：网卡的设置是在网卡的硬件设置属性里选择高级，那里有很多参数可以设置的。每次设置之后，我都将dynamips重新启动一下，否则修改参数后，连网关都ping不通了。
如果你觉得好，就请顶一下，让更多的人能够看到。谢谢！
根据上面大侠的方法，解决了PING不通的问题
但是连上SDM后，就停在下面那里不动了，大侠们，谁知道啊怎么办啊，谢了先！！！
