The Virtual PC Simulator for Dynamips

Esta herramienta te permite simular hasta 9 seudo-PCs que solo soportan los comandos de PING y TRACE . No soporta DHCP ,TELNET ,FTP ,etc etc...
Util para labs con access-list , route-map , etc etc... ( los ping y traces extendidos no son muy utiles para testear estos features ) .

EL manual online esta bien documentado.

El archivo cygwin1.dll del vpc , entra en conflicto con el cygwin1.dll del dynagen y aparece este mensaje :

4752 [main] ? (408) C:\Archivos de programa\Dynamips\dynamips.exe: *** fatal
error - system shared memory version mismatch detected - 0x2D1E009C/0x75BE0096.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version. The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution. Rebooting is also suggested if you
are unable to find another cygwin DLL.
Presione una tecla para continuar . . .

Lo que se hace es copiar el cygwin1.dll del dynagen en el directorio del vpc y se soluciona este problema .

Aqui el seteo en el dynagen y el vpc .
