My Howtos and Projects: Cisco IOS on UNIX (IOU)Cisco IOS on UNIX (IOU) is a fully working version of IOS that runs as a user mode UNIX/LINUX process. IOU is built as a native system image and run just like any other program. IOU supports all platform independent protocols and features. With regard to functionality, it is very similar to GNS3 but it does not require nearly the resources that several virtual routers running under dynamips does. IOU allows you to build out a network topology on a single PC without the need for physical routers. This is useful for validating network designs, proof- of- concept testing, and certification self- study.
If you are not an authorized Cisco employee (or trusted partner), usage of Cisco IOU is prohibited. From an old, internal- only Cisco web page: Cisco IOS on Unix is a tool intended for internal use only.

This may not always be the desired behavior, especially if you wish to telnet to the console from another host on the network (similar to dynamips).
The wrapper program can be used to redirect a TCP port to the console of the router so that you can do exactly this. How do I use the Wrapper$ ./wrapper. Usage: ./wrapper . Any options after the double- hyphen (- ) are passed off to the IOU image so, in this case, our IOU instance would start up with zero Ethernet interfaces (- e. Wide Port Adapters'', and 6.
