SSH Connection between the linux hosts

Hello  folks,

Here I would like to give steps to build a SSH connection between two Linux hosts.

Example hosts: abc.com & xyz.com

1. Login to abc.com
2. Navigate to "$cd .ssh/" directory from root. Incase the directory is not available simply create it in root "/".
3. Execute the following command "ssh-keygen -t rsa"
4. Change the permissions to "id_rsa.pub" file "chmod 600 id_rsa.pub"
5. Do cat id_rsa.pub and copy the content.
6. Create "authorized_keys" file in same directory. Do vi and paste the content. If file is already exist paste the content at bottom of the file.
7. Create "authorized_keys" file in .ssh/ directory in remote host (xyz.com). Do vi and paste the content.
8. Perform steps 1 to 6 in remote host (xyz.com) and copy the content in "id_rsa.pub" and paste it in "authorized_keys" file in remote host(abc.com).
9. Execute the following command to check the SSH connection.
1. Login to abc.com
2. $ssh xyz.com (First time it will ask password to login xyz.com)
3. Execute same command in xyz.com to check ssh connection to abc.com.

Hope this post will useful.
