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. 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.
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 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.
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.
There have been reports of compromised IOS images making the rounds. Thanks for the replies, I've managed to get an image, I appreciate the points that you all have made and that the images are copyrighted to Cisco, and I'll be thinking very carefully when next buying a car! I've used packet tracer and I have 2 router and a switch it just they're noisy, take up space and I though using GNS3 would just be more convenient.
You'd think that Cisco would buy GNS3 and sell it of market it. You can also run it on from the Cloud or someone else's computer to give it it's real name. I saw an online network training site that publicly hosted several ios images for download awhile back.
My understanding is that this is completely illegal. I'm not sure how they were getting away with it. Doubt it. That little guy is going to pay for his CCNA and maybe a CCNP and chances are he'll be drinking at least some of the Cisco kool-aid for the rest of his networking life. I'll bet Cisco bank on getting more sales from "on-boarding" Cisco acolytes than they would if they were seen to be harsh with people who, at the end of the day are likely to recommend and use MORE Cisco kit and not less.
The same goes for the "un-official" re-sellers. At the end of the day if a business or whatever buys a bit of Cisco gear, who is going to be making money? And lets be clear, I do not condone illegal file sharing of any kind but come on, lets elevate the thinking beyond the actual small print and live in the real world.
I firmly believe Cisco turns a blind eye to a lot of this "grey market" activity in pursuit of the greater for them good. Doesn't do us Cisco engineers who need lab gear any harm either. All in all I think if Cisco were to start firing law suits across the globe to protect their IOS's especially "old" IOS's would do them a great deal of harm indeed.
Buying used gear is in no way breaking the law. Please google court case agaisnt cisco. Grey market gear is not illigal you just won't get support and it's frowned apon.
Cisco even gives free ios updates you just have to write a email to tac with a show ver, then show them the vulnerability your facing and they want serial too to make Sure it's not stolen.
Cisco has to update their equipment if there is a vulnerability it says so on their site. I have done it many times! Has anyone else been brave and done the above? Every single person even remotely resembling a networking professional that works with Cisco equipment has always said that your gray market switches and routers should never talk to the internet or they will "phone home" and really bad things will happen. I've had a "grey market" lab of about 20 bits of Cisco gear for over 10 years and it's ALL been "on the internet" continuously for about 5 years.

Follow Us. If none of these work, you can search the following term on Google. You may check the following site. I found this site through a Google search. It may be may not be working at this moment. By default, IOS files are compressed.
GNS3 supports both compressed and decompressed formats. Compressed files not only consume less space but also easier to manage.
Unless you have a particular reason to keep IOS files in their original form, click the No option to keep them in compressed format. In real life, using an outdated device is not recommended. If you only want to use this device for exam preparation or to get some hands-on experience on Cisco IOS, you can ignore this message.
On the next step, the wizard extracts the hardware information platform and chassis number from the selected IOS file and lists the information on the next screen along with an automatically populated device name.
If the extracted information is incorrect, select the correct platform and chassis number from the drop-down.
