SSH Login without Password
To login in SSH without password, we need to do the following:
1. Generate a key pair (private key and public key) in Server A ssh-keygen -t rsa
2. Copy the public key from Server A to Server B. scp id_rsa.pub username:[server_B_ip_address]:/home/username/.ssh
3. In Server B, add that public key into authorized_keys file. cat id_rsa.pub >> authorized_keys
4. Verify it from Server A. ssh username@[server_B_ip_address]
