You’re looking for a pair of files named something like iddsa or idrsa and a matching file with a.pub extension. The.pub file is your public key, and the other file is the corresponding private key. SSH2 was introduced in 2006 with many significant improvements over SSH1. Although it is an improvement of SSH1, SSH2 is not compatible with SSH1. SSH2 is re-written with adding more defensive mechanisms to avoid vulnerabilities.

Secure remote access with Linux bastion hosts on the AWS Cloud
This Quick Start adds Linux bastion hosts to your new or existing Amazon Web Services (AWS) infrastructure for your Linux-based deployments. The bastion hosts provide secure access to Linux instances located in the private and public subnets of your virtual private cloud (VPC).
The Quick Start sets up a Multi-AZ environment and deploys Linux bastion host instances into the public subnets. You can specify the instance type for the bastion hosts and the number of instances you want to deploy (1–4).
An Amazon Elastic Compute Cloud (Amazon EC2) Auto Scaling group ensures that the number of bastion host instances always matches the capacity you specify. For added security, the Quick Start also sets up Amazon CloudWatch Logs for remote storage of shell history logs. After you deploy this Quick Start, you can add more AWS services, infrastructure components, and applications to complete your Linux environment in the AWS Cloud.
This Quick Start was developed by
AWS solutions architects.

- What you'll build
Use this Quick Start to set up the following networking environment on AWS: Among the sleep for mac.
- A highly available architecture that spans two Availability Zones.*
- A VPC configured with public and private subnets according to AWS best practices, to provide you with your own virtual network on AWS.*
- An internet gateway to allow access to the internet. This gateway is used by the bastion hosts to send and receive traffic.*
- Managed network address translation (NAT) gateways to allow outbound internet access for resources in the private subnets.*
- A Linux bastion host in each public subnet with an Elastic IP address to allow inbound SSH (Secure Shell) access to Amazon EC2 instances in public and private subnets.
- A security group for fine-grained inbound access control.
- An Amazon EC2 Auto Scaling group with a configurable number of instances.
- A set of Elastic IP addresses that match the number of bastion host instances. If the Auto Scaling group relaunches any instances, these addresses are reassociated with the new instances.
- An Amazon CloudWatch Logs log group for the Linux bastion host shell history logs.
* The template that deploys the Quick Start into an existing VPC skips the components marked by asterisks and prompts you for your existing VPC configuration.
- How to deploy
To add bastion hosts to your Linux environment on AWS, follow the instructions in the deployment guide. The deployment process takes about five minutes and includes these steps:
- If you don't already have an AWS account, sign up at https://aws.amazon.com, and sign into your account.
- Launch the Quick Start by choosing from the following options. Before you create the stack, choose the Region from the top toolbar.
- Add other AWS services or your Linux applications.
Amazon may share user-deployment information with the AWS Partner that collaborated with AWS on the Quick Start.

- Cost and licenses
You are responsible for the cost of the AWS services and any third-party licenses used while running this Quick Start reference deployment. There is no additional cost for using the Quick Start.
The AWS CloudFormation templates for this Quick Start include configuration parameters that you can customize. Some of these settings, such as instance type, affect the cost of deployment. For cost estimates, see the pricing pages for each AWS service you use. Prices are subject to change.
Tip: After you deploy the Quick Start, create AWS Cost and Usage Reports to track costs associated with the Quick Start. These reports deliver billing metrics to an Amazon Simple Storage Service (Amazon S3) bucket in your account. They provide cost estimates based on usage throughout each month and aggregates the data at the end of the month. For more information about the report, see What are AWS Cost and Usage Reports?
An SSH server is a software program which uses the secure shell protocol to accept connections from remote computers. SFTP/SCP file transfers and remote terminal connections are popular use cases for an SSH server.

Platform[edit]
Ssh V2 Keys
The operating systems or virtual machines the SSH servers are designed to run on without emulation; there are several possibilities:
- No indicates that it does not exist or was never released.
- Partial indicates that while it works, the server lacks important functionality compared to versions for other OSs but may still be under development.
- Beta indicates that while a version is fully functional and has been released, it is still in development (e.g. for stability).
- Yes indicates that it has been officially released in a fully functional, stable version.
- Dropped indicates that while the server works, new versions are no longer being released for the indicated OS; the number in parentheses is the last known stable version which was officially released for that OS.
- Included indicates that the server comes pre-packaged with or has been integrated into the operating system.
The list is not exhaustive, but rather reflects the most common platforms today.
