Tutorials for AWS Beginners how to connect two EC2 instances without keypair using SSH - Basic AWS Tutorials

In this video you will see how to connect two AWS Rhel EC2 instances without Keypair using ssh

Here's what I did on a AWS RHEL 8 EC2 Instances:

A) Login as root using the keypairs

B) Setup the necessary users and their passwords (Both ec2 servers) with
# sudo adduser awsadmin
# sudo passwd awsadmin

C) Edit /etc/ssh/sshd_config setting (Both ec2 servers)
For a valid user to login with no key
PasswordAuthentication yes

D) Restart the ssh daemon (Both ec2 servers) with
# service ssh restart

E) Create SSH ID in one of the AWS EC2 instnce
#ssh-keygen

F) Copy the ssh id to another server
#ssh-copy-id ip.address.of.target.server

After this one can connect from one ec2 to another ec2 using ssh commands without keypair

#ec2 #keypair #sshd #sshd_config #visudo #rootuser #createuser #awstutorials #rhel #linux
