In Python3, print in now a function. Meaning you should have something like this print () not ' as it was in the earlier versions of Python.
i.e. print '*********************************************************************' becomes
print ('*********************************************************************')

Hey guys,
I faced the same problem that you'all are facing. First of all let me tell you that IOU is available only to the Cisco Employees. So if you're not the one you can't use it. But that's not the case.! You can get you own IOU license if you have a blank VM with Linux installed. Web IOU will also do.
Just follow the steps:
1. Change the hostname and hostid in the new VM.
2. Change hostname with gns3-iouvm
type command as
hostname gns3-iouvm
now type command hostid, you should be able to see 00000000 ( 8 0's )
3. There is python crack which is available on net ( I am attaching the file )
4. Copy the CiscoIOUKeygen.py to your new VM using WinSCP.
5. Execute the file as per the link
http://vmgeeks.wordpress.com/2012/07/21 .. ware-esxi/
6. Once thy python file has been executed you will be able to see your own license.
Need any help feel free to ask.
Regards,
Nirav Dave.

I'd recommend running the keygen.py file using python 2.7 and not version 3.. as thats what works for me.
if you need to change the hostid, you can use this shell script to set a value you like..
http://fazlearefin.blogspot.com.au/2013 .. hosts.html
If you need, to make a copy of the keygen.py file and then statical set your hostid and hostname variables in the file and run it.

I have managed to port the script to be compatible with both python 2.7 and python3.
I have compared the output from the amended script and the original.. both generate the same for me!

You shouldn't need sudo to run the script.. It does othing that would require root privileges

ok so I put the script on a directory in my vm iou that I downloaded here.
And what is the command then to execute that script?
Do I have to edit the script - so put in the Host-ID and Name?
thanx a lot,
cheers,

Hey guys,
I am not exactly a noob when it comes to Unix/Linux, but I am also not an expert. Anyway, I have literally spent countless hours over the course of the last couple of weeks trying to get the IOU license to generate and let me begin to build my topology. I have read and followed the steps for cracking the license file outlined in this forum but I am still not able to get it to work. Here is my first issue when attempting to power on my IOUs:
IOU License Error: invalid license
License for key 3d8 required on host 'gns3-iouvm'.
Obtain a license for this key and host from the following location:
http://wwwin-enged.cisco.com/ios/iou/license/index.html
Place in your iourc file as follows (see also the web page
for further details on iourc file format and location)
[license]
gns3-iouvm = <16 char license>;
I tried executing the CiscoIOUKeygen.py that someone kindly posted (python command does not work) and this is the output I see:
[email protected]:/home# bash CiscoIOUKeygen.py
Warning: unknown mime-type for '*********************************************************************' -- using 'application/octet-stream'
Error: no such file '*********************************************************************'
Warning: unknown mime-type for 'Cisco IOU License Generator - Kal 2011, python port of 2006 C version' -- using 'application/octet-stream'
Error: no such file 'Cisco IOU License Generator - Kal 2011, python port of 2006 C version'
CiscoIOUKeygen.py: line 4: import: command not found
CiscoIOUKeygen.py: line 5: import: command not found
CiscoIOUKeygen.py: line 6: import: command not found
CiscoIOUKeygen.py: line 7: import: command not found
CiscoIOUKeygen.py: line 9: syntax error near unexpected token `('
CiscoIOUKeygen.py: line 9: `hostid=os.popen('hostid').read().strip()'[/color]
I am running Debian Jessie (same IOUvm provided on the GNS3 website). Also, here is are the contents of my IOURC file:
[license]
gns3-iouvm = 1020304050607080
*NOTE - I manually input the 16-character value seen above in the IOURC file.
Any help would be greatly appreciated.

The IOU license script shouldn't be run using bash (aka shell), as it is written in python. (They're different interpretors)
Grab the script from: post28850.html#p28850 which will work with python 2.7 or python 3
From the terminal type in:
This will then generate your license code

Hi Dan,
Thanks for your response. I tried running the script after uploading it to my VM but it still comes up with errors:
[email protected]:/home/gns3/Documents/GNS3/images# python CiscoIOUKeygen10.py
bash: python: command not found
Any ideas?

Posted: Fri Apr 25, 2014 4:07 am

Yes, try python3

Hi Jeremy,
Thank you for the quick response and sorry for my delayed response! I ran the following command shortly after posting my last message to this thread:
python3 CiscoIOUKeygen.py
That command executed without issue. I added the license key to my IOURC file and it worked like a charm!
Thanks again to both you and Daniel for helping me out!!!

do you have to edit anything in the file? I got an error
python3 CiscoIOUKeygen.py
File 'CiscoIOUKeygen.py', line 2
print '*********************************************************************'
^
SyntaxError: invalid syntax

Posted: Fri May 30, 2014 3:40 pm

Try the updated version of the script.. post28850.html#p28850
