Generate Cisco IOURC license key on GNS3 VM using Python 3

When I wanted to add IOU L2 Switch image on GNS3, I got the following license error.

gns3 license error

When I checked the license, I realized there was no license key.

I explained the solution :

1- Access the shell of your VM

2. Download the Keygen using the following command.

3. After download, run the following command to generate the license.

4. After running this command, a file called iourc.txt will be created.

5. Copy and paste the license key in the file to the Preference> IOS on UNIX section of GNS3.

6. Finally, everything is green😀!!!
