ssh-keygen: password-less SSH login script
This utility uses ssh-keygen and ssh_copy_id to create RSA private/public key pairs for use by SSH protocol version 1 and RSA or DSA keys for use by SSH protocol version 2. The public key is then copied onto a remote system. You can now SSH to the remote system without the use of a password from the specified machine.
If the file /etc/root/.ssh/authorized_keys exists on the destination system, you probably already have it setup.
For more information see the man pages for ssh-keygen and ssh_copy_id.
- Download trusted-key-exchange-1.3.tgz
- Open a Terminal window and type “su”
- Enter root’s password
- Extract the script from the tarball
#tar –xzvf trusted-key-exchange-1.3.tgz
- Make the script executable.
#chmod 755 trusted-key-exchange-1.3.sh
- Create the shared keys between two Linux systems
- Now ssh to the Linux system and it will not prompt you for the password.
Fixed in the 1.1 version:
- The script will now allow you to have trusted hosts setup between multiple systems. It now supports a one to many relationship.
- The prompts necessary during the script have been reduced.
