We hear this question on a pretty regular basis. “I paid for credits, spent the credits on a lab, took the lab, and you’re telling me I have to spend more credits to take the lab a second time?” It’s a valid question, and the answer is worth exploring (TLDR: subscribe to qwikLABS and take a lab as many times as you want!).
The hands-on qwikLABS approach is dramatically different from other sources of online training. A lab is not like a book that you buy and read over and over. A lab is more like a sandwich – you only eat it once.
PuTTY is a (free) SSH client. It gives you a command line tool, and allows you to control the remote host you create as part of your lab. You need PuTTY if you are using a Windows PC. If you use a Mac or a Linux machine, you’ll follow a different set of instructions.
Where do I get it? Is it free? Is it safe to download?
Read about it here. (Safely) download the most recent version here.
Once I get it, how do I use it? Screenshots please?
Once you get to PuTTY in the lab instructions, find the putty.exe file (likely in your Downloads folder) and double-click to launch it. Instructions will vary (so follow the instructions in your lab), but you’ll probably want to enter a host name like this*:
Expand the Connection tree, then expand SSH, then click (don’t expand) Auth.
You’ll see a field for your private key – browse to the PPK file provided by the lab (likely in your Downloads folder).
Wait, PPK file? Where do I find that?
Both the PPK file and the PEM file (if you need it) can be downloaded from your lab instructions.
When you connect, you might see a message like this (fascinating right?) – click yes to make the connection.
…and you’re in! Now you’re a pro. When was the first time you used PuTTY?
