If the software images do come from anywhere other than the official Cisco software repository (including preinstalled on used gear) you really need to check the MD5 signature against the official Cisco version. I don't know of any cases of Cisco taking legal action to enforce their intellectual property rights against a re-seller and I'd be very surprised if they took exception to someone using their software in a "virtual" GNS3 environment.

Of course there are dozens of Cisco re-sellers that sell used gear and those that do it the official Cisco way (sending the equipment back to Cisco for official re-licensing and charging again for the licensing) are obviously at a serious pricing disadvantage. I expect the automobile manufacturer's lawyer wasn't a software licensing specialist and used a lot of boiler plate text from somewhere else without actually realizing the real implications. That said, I carefully reviewed the license for the software that makes my car work and it's not transferable either so in some cases buying a used car is just as illegal (technically - no court would ever entertain that you did something illegal with regard to software licensing in buying a used car). And they're available inexpensively or even free.īuying used gear is most often technically just as illegal as grabbing the images from some file sharing site because the licenses are not transferable. There are a lot of switches, routers, and firewalls out there that, although not the latest, are still quite functional.

GNS3 is an excellent alternative or complementary tool to real labs for network engineers, administrators and people studying for certifications such as Cisco CCNA, CCNP andCCIE as well as Juniper JNCIA, JNCIS and JNCIE.If your goal is to run GNS3, then you need to get the IOS images in an appropriate way.īut, if you're trying to work with a lab setup, consider getting the actual physical gear. QEMU, a generic open source machine emulator, it runs Cisco ASA, PIX and IPS.VirtualBox, runs desktop and server operating systems as well as Juniper JunOS.Dynamips, the well known Cisco IOS emulator.In order to provide complete and accurate simulations, GNS3 actually uses the following emulators to run the very same operating systems as in real networks:

GNS3 provides an intuitive graphical user interface to design and configure virtual networks, it runs on traditional PC hardware and may be used on multiple operating systems, including Windows, Linux, and Mac OS X. GNS3 is an open source (GNU GPL) software that simulates complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches. If you face any problem setting it up with GNS3 drop me a message and I will get back to you asap. Old ones are kept intact for your reference.
