Humphrey Cheung (http://www.routergods.com/) has created a video tutorial showing how to get GNS3 WorkBench up and running.
Thanks Humphrey – but a couple of comments:
1. GNS3 WorkBench likes uncompressed images with a .image extension for the prepared exercises – in fact it checks to see if there is a “*.image” file in the IOS directory at the start of each prepared exercise. There are instructions on how tho turn a .bin file to a .image file in the IOS directory. In your example you would run the command:
unzip -p c3725-adventerprisek9-mz.124-15.T5.bin > c3725-adventerprisek9-mz.124-15.T5.image
2. The prepared exercises were prepared using the .T10 rather than the .T5, so to make your c3725-adventerprisek9-mz.124-15.T5.image work with the prepared exercises, you’d also need to run the script script to change firmware image also found in the IOS directory – it runs something like this:
Do you have a backup of your /opt/GNS3/Project directory y/n/eXit? [n]:y c3725-adventerprisek9-mz.124-15.T5.image /opt/GNS3/IOS Enter the current image - the one you need to replace (Ctrl+c to abort) [c3725-adventerprisek9-mz.124-15.T10.image]:<Enter> Enter the replacement image name (Ctrl+c to abort) [c2600-advsecurityk9-mz.124-25b.image]:c3725-adventerprisek9-mz.124-15.T5.image
If you carry out these extra two steps, then your GNS3 WorkBench will work for all the exercises too.
