Im pretty new to SSH and havent really setup a connection before and was hoping to find some guides. &nbsp;I was searching online but nothing really gave me what I was looking for. <br />
What Im trying to do is setup an SSH connection using putty as the client to a Linux machine (VMware ESX). &nbsp;I plan on using it in conjunction with plink so that I can use it to power off the Linux box in the event of power failure. &nbsp;I dont want to type the password in the plink connection for security reasons, Id want to have it setup to authenticate with certificates. &nbsp;Im not exactly sure how to setup the Linux box to use a certificate for it.<br />
If youd like I can list the steps I have taken so far but Im not entirely sure how well it is setup and would prefer a guide on from start to finish or if someone could point me in a the direction of a good how to I would greatly appreciate it.<br />

Setting up a SSH connection

Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. SSH was designed as a replacement for Telnet and for unsecured remote shell protocols. The term telnet is also used to refer to the software that implements the client part of the protocol. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.

SSH / Telnet Software

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

The Linux operating system, in all its flavors, has its own share of security flaws that allow intrusions, but there are various mechanisms by which these flaws can be removed, generally divided into two parts: authentication and access control. Authentication is responsible for ensuring that a user requesting access to the system is really the user with the account, while access control is responsible for controlling which resources each account has access to and what kind of access is permitted.
