Recently I was working on AWS and was deploying applications on a Fargate cluster. I wanted to make sure the application was up and running and the ports were accessible by other applications. For that purpose I created a bastion host (EC2) but because of the restrictions on my role, I could not install telnet or nc on that EC2 instance.
But I was able to connect to the ports using the below bash command
</dev/tcp/10.191.226.250/13133 && echo Port is open || echo Port is closed
Being able to securely connect to remote hosts from windows using SSH is a very important and common requirement, especially when you are working with remote linux servers. SSH is a high-security protocol. It uses strong encryption to shield your connection from eavesdropping. capture, and other sorts of attack. In this post we will discuss exactly how to do this using PuTTY tool. We will also show how to create and save PuTTY sessions and discuss how to configure login without password using key pair.
