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 😍

SSH Reverse Tunneling is super useful to get remote systems connected which only have very limited internet access through mobile carriers. They usually do NAT and you have no chance to connect to these sites with a dial-in VPN or other technologies that require YOU to connect to the remote system. So we just create a reverse ssh tunnel with autossh that is kept alive by the remote system itself and we connect back to the system to the ssh tunnel. Since ssh is installed anyway, that is one of the simplest and most versatile options to connect to these systems for us.
