GNS3 - How to find Pix Images, Pix Serial Numbers and IOS images using Google
Posted by Josh under Cisco , Cisco Routers , Dynamips , GNS3 , PEMU -One of the major hurdles many people face with GNS3/Dynagen/Dynamips is that the emulators do not come with the Cisco Images to actually build a lab. It seems like once a week, I get an email with a request for an IOS Image, Pix Image, Pix Serial Numbers or Pix Activation codes. Just so I make myself clear, I will not give this information to you. Period. However…
However, I will show you how to scan the net to get it yourself.
Google Searches:
Google Search for IOS Images
Google Search for Pix Images
Google Search for Pix Serial Numbers and Authorization Keys

I’ve gotten a few requests like that myself, Josh. It’s definitely not worth being in trouble with Cisco because someone else wants you to pirate software for them.

Hi Josh,
Thanks for all the information that you are posting here. I am a newbie to GNS3 and had never used dynamips before. I downloaded IOS images and have tried it but when I tried the console, nothing appears on it. can you help me to know which IOS image I need to use to make those routers work?
Thanks a lot.

Really - good work!
Your seem to love this GNS3 like us all.
Maybe this GNS3 / dynamips / PEMU and your tutorial site are some of the best resources for Cisco Learners in this part of the galaxy!
Another good resource to me has allways been http://www.sadikhov.com website. BRILLIANT Resources for all kind of certifications, trainings and finding interesting networkers around this planet.
I still have trouble to get activation key running in my pemu / pix. I invested the whole day in this cause i want to do some training on ipsec vpn but the feature is licensed and i can not activate.
but i simply was not able to get the activation key running.
We run several pixes on the company, i have serial and activation key but anything i tried out was not successfull. ;-(
Maybe someone has some “hint” step by step what could be the problem? I tried to give in my serial and act. key on GNS3, i tried on gns3.ini, i tried on pemu.ini, i deinstalled gns3 maybe 5 times and i am tired now from trying. I tried with several pix os versions (from 6 -
The whole functionality of GNS3 is really breathtaking, i simply love this environement and i thank to all the people who made this possible.
Thank you!

Sorry guys for going on your nerves - i HAVE a valid serial and i HAVE a valid activation code and i HAVE the PIX OS from a “real” pix where this act. code works.

@spacyfreak,
Add the serial number and activation key to Pemu section of the preferences. Right below the pix image.
