From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

A Visual Guide to SSH Tunnels: Local and Remote Port Forwarding (iximiuz.com)

SSH is yet another example of an ancient technology that is still in wide use today. It may very well be that learning a couple of SSH tricks is more profitable in the long run than mastering a dozen Cloud Native tools destined to become deprecated next quarter.

One of my favorite parts of this technology is SSH Tunnels. With nothing but standard tools and often using just a single command, you can achieve the following:

Access internal VPC endpoints through a public-facing EC2 instance.
Open a port from the localhost of a development VM in the host's browser.
Expose any local server from a home/private network to the outside world.

And more 😍

The clean new syntax for jumping is great too.

ssh -J jump.example.com target.example.com
