This post is to act as the index for the series of blog posts written on SSH. In the series, we discussed on what is SSH, how it works, different configuration options and few advanced features such as SSH tunneling. It can be used to get a quick overview of and navigate to find the related post of interest.

Part 01 – Basics of SSH, How it works, Various authentication methods, Generate SSH Key pairs

This is the fifth post in the series of the blog posts about Secure Shell aka SSH. You can find the series index here. In this blog post, we’ll discuss about SSH tunneling and how to configure and use the same.

SSH port forwarding or SSH tunneling, is a mechanism in SSH for tunneling application ports from the client machine to the server machine or vice versa. It can be used for variety of purpose such as adding encryption to legacy applications, bypassing firewalls, opening backdoors into internal networks, etc. It is a double edged sword. It can be useful at the times but it can also be abused by hackers and malware to open access from the internet to the internal network.

This is the fourth blog post in the series of blog posts on the Secure Shell aka SSH. You can find the series index here. In the last post, we discussed how to customize SSH uing the server side configuration options. We discussed some of the most popular options and also shared location for list of full options available. In this blog post, we’ll discuss how we can customize the SSH session using some of the popular client side configuration options. Using these options can shape the way the connection is established and connection experience for the ssh clients.

This is the third blog post in the series of blog posts on the Secure Shell aka SSH. You can find index here. In the last post, we discussed how to copy ssh public key to the remote server and then discussed few local options to create and customize ssh sessions. We also discussed about the usage of ssh-agent. In this blog post, we’ll discuss how we can customize the SSH session using some of the popular server side configuration options. Using these options can shape the way the connection is established and connection experience for the ssh clients.

This is the second post in a series of blog posts on SSH. You can find the series index here. In the last blog post, we had overview of SSH protocol and how SSH authentication works. Then we discussed how to generate an SSH Key pair. As we discussed previously, we need to copy the SSH public key to the remote server and few other connection options. In this blog post, we are going to discuss the same.

Copying SSH Keys to the remote server

There are many ways to copy the public key generated to the remote machine. Below are some of the ways to copy the key.

In a world full of Linux servers, containers and clients, SSH is one of the most used and most less understood protocols. Newer services such as related to container tooling, SSH over SSL have further abstracted away this protocol. But nevertheless, SSH continues to remain the primary means of establish connections with linux based operating systems and perform routine system administration and management related tasks. It also continues to be base of other important protocols / services such as SFTP, SSH tunneling, Virtual Private Network etc. This blog is first in series of blog posts about SSH or secure shell protocol, where we’ll discuss most of the things one should know about SSH.
