If not already set, file permissions for ~.ssh need to be set to 700 as follows: If the public key is disabled, check the configuration file named /etc/ssh/sshd on the target computer for the following settings: ssh]# ssh-copy-id -i my_id.pub You should now be able to login into the remote machine without a password. That is, copy it to the system that you want password-less SSH access to, which in this example is. Copy the public key to the destination system. Id_dsa.pub identity.pub id_rsa.pub known_hosts my_id.pub. Navigate to the directory in which you created the keys and verify that the process succeeded. You have new mail in /var/spool/mail/rootĢ. Your identification has been saved in /root/.ssh/my_id. ssh]# ssh-keygen -t rsaĮnter file in which to save the key (/root/.ssh/id_rsa): /root/.ssh/my_idĮnter passphrase (empty for no passphrase): The following is an example of the command and subsequent. Note: When you generate these keys, do not enter a passphrase. pub (public key) that you share with remote computers and a private key that you never share. The following procedure configures password-less SSH:ġ. SSH is ideal for managing remote systems because of its password-less option that uses keys instead of passwords, keeping system passwords safe. This article uses ssh-copy-id, a utility that greatly simplifies the procedure by copying the local host’s public key to the remote host’s authorized keys file and by verifying file permissions and ownership. Note: This article, which describes how to set up an SSH login that does not use passwords, applies to RHEL5.
