Dynamips/VMWare/Windows/Fedora/SDM and all that :)
Well since I am now studying for my ISCW it was time to test SDM and how it works. None the less it only works on Windows operating systems. First couple of practices I did went with no problem, but as soon as I got to 3 routers and some tunneling and encryption I got the popular memory stack problems. Needing to alleviate this problem I sat down and thought hard. Having before tried the Windows inside Linux and vice versa, I knew there was no really good solution. Finally it came to me that while trying Fedora inside VMWare on Windows I was running the InternetworkExpert topology with something like 15ish routers. Sitting on 3 routers inside VMWare on Fedora and using SDM from my host Windows really works cool. And its not a problem to setup.
1. After you have everything setup for host/guest communication with VMWare start the Dynamips process on Linux
2. On Windows create your .net file and set it up so that each router has an interface pointing out through the VMWare interface to you host machine.
3. Add addressing on those interfaces and ping them from the host machine, should work.
4. Connect with your SDM to the routers
Happy securing and device hardening
