Procedure 2. Using RSA authentication without a passphrase
To enable ssh without a passphrase, complete the following steps.
1. Generate the RSA keys by typing the following command:
% ssh-keygen -t rsa -N ""
2. Create a $HOME/.ssh directory and set permissions so that only the file's owner
can access them by typing the following command:
% mkdir $HOME/.ssh
% chmod 700 $HOME/.ssh
3. The public key is stored in your $HOME/.ssh directory. Copy the key to your
home directory on the remote host (or hosts) by typing the following command:
% scp $HOME/.ssh/key_filename.pub \
username@system_name:.ssh/authorized_keys
Note: This step is not required if your home directory is shared.
4. Connect to the remote host by typing the following command:
% ssh remote_host_name
