GNS3 on VMWare ESXi - Useful Links

After getting GNS3 up and running under ESXi, I found these links useful:
GNS3 Latest Version
Be sure to use the GNS3 frontend version which corresponds with your server version.  When installing the frontend on your client PC, you only have to select GNS3, nothing else (dynamips, etc.).  Be sure to update after updating server version as well.
Installation
Very straightforward, follow the doc and it should work - do note the ESXi 6.5 caveats/required updates.
IOS images
If you must
Appliances
Lots of cool stuff here, the appliance file will usually guide you to any additional image files which need to be downloaded and can then be imported via GNS3 frontend
IOU images
I don't know about the legality of this, but we're all using the product for educational purposes and to better ourselves - I don't yet know of another way of getting the required IOU images.
Generate IOU license
Note that the http://gns3host:8000/upload method is no longer used, configure your IOU settings and license via GNS3 frontend: Edit -> Preferences... -> IOS on UNIX.  Run linked script on GNS3 server host and look for iourc.txt output file in /home/gns3 if using default user settings.  Upload that file and note other instructions output by script.
