Once upon a time I wanted to be an engineer, so I took a lot of math classes. Trigonometry, pre-Calc, Calc I, Calc II. Then I ended up switching to Chemistry (the 4 year college I transferred to had a great Chem program and no Engineering program, go figure) and my class load changed. I had to take a biology class and the instructor put down such terms as “average, mean, standard deviation” and I was lost. I’d never taken “slacker math” which is what all the engineer students called “Probability and Statistics.” So, in order to pass a course on biology I found a used Prob and Stats textbook at the local Goodwill and figured out how to do the math necessary to pass the course.
Lately I’ve found myself in a similar situation. In getting ready for the CCNA Security exam I’m following along with the CBT Nugget videos, and the instructor exclusively uses GNS3 on a Win 8.1 box as the software for the labs. Up until now Packet Tracer and actual hardware were what I’d used in my home lab, but what the heck, I’m a smart guy right? I can figure out this whole other program. So that’s what I’ve been doing, except instead of Win 8.1 (never bought it, have Win7 and 10) and somehow GNS3 changed just enough that the install and configuration videos available on CBT Nuggets doesn’t work with my gear.
So after about five days of trying to make it work, I hooked up a spare 300 gig HDD and loaded Linux Mint on it, and got GNS3 up and running with a Cisco ASA emulated inside of 3 hours. But the next challenge is the Cisco ASDM or CCP software. Next challenge is figuring out how to translate all the “now load up a management PC by setting up the Microsof loopback adapter” crap in the videos to the Linux version (thank you university of youtube) and installing the ASDM software on the emulated ASA.
This sort of thing is actually normal in IT. “You want to do this? Sure you can do that, but first you need to do that, the other thing, and sacrifice a chicken.” So that’s why content has been scarce, because I’m doing a lot of extra work all to save myself about a hundred bucks for an Ebay Cisco 5505 Adaptive Security Appliance. But…it’s one of those things where if you are in IT people expect you to be a GNS3 guy now because you can emulate a lot more hardware than just Cisco products, and damn if I shouldn’t have spent the time to learn all this crap before. Of course there won’t be a single GNS3 question on the CCNA Security exam, but sometimes you have to learn for the sake of learning, and not just to pass a test.
I have no idea when the content pace will pick back up, sorry.
