Remotely connecting from Windows desktops

I know, all of us Penguinistas would like to use Linux, and nothing but Linux. But, in an enterprise environment, things just don’t always work that way. There, you’ll most likely have to administer your Linux servers from a Windows 10/11 desktop machine that’s sitting on your cubicle desk. In Chapter 1, Running Linux in a Virtual Environment, I showed you how to use either Cygwin or the new Windows 10/11 shell to remotely connect to your Linux VMs. You can also use these techniques to connect to actual Linux servers.

But, some shops require that admins use a terminal program, rather than a full-blown Bash shell such as Cygwin. Normally, these shops will require that you use PuTTY on your Windows machine.

PuTTY is a free program that you can download from here: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

Installation is simple. Just double-click the installer file and follow through...
