2. Connect to your instance using Xshell
Open the AWE EC2 consol at https://console.aws.amazon.com/ec2
In the Launch instance box, click the "Launch instance" if no instance is running, otherwise, click the "Instances (running)" under "Resources".
Change Security group settings by clicking the security group ID, and then "Edit inbound rules". This step is important if you want to SSH to EC2 using port 22.
4. Add rule, and then select "SSH" with "Anywhere - IPv4".
5. Import the secret key file ".pem" into Xshell. This file should be generated when setting up your instance in step 1. Open Xshell, tools - User Key Manager - Import, and select the ".pem" file.
6. Follow the steps below to build your connection, where the Host ip is taken from the "Public IPv4 address" as shown below, and the default "User Name" is:
For Amazon Linux 2 or the Amazon Linux AMI, the user name is ec2-user.
For a CentOS AMI, the user name is centos or ec2-user.
For a Debian AMI, the user name is admin.
For a Fedora AMI, the user name is fedora or ec2-user.
For a RHEL AMI, the user name is ec2-user or root.
For a SUSE AMI, the user name is ec2-user or root.
For an Ubuntu AMI, the user name is ubuntu.
For an Oracle AMI, the user name is ec2-user.
For a Bitnami AMI, the user name is bitnami.
Otherwise, check with the AMI provider.
7. Connect to EC2, and use cat /proc/cpuinfo and du- H to check the CPU and storage information.
