You will need to create a public key on the installer system for SSH login into Telco Cloud Operations virtual machines.
Complete the following steps to create public key.
- Run the ssh-keygen command. See the following code block as an example.
$ ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/home/user_name/.ssh/id_rsa): Created directory '/home/user_name/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/user_name/.ssh/id_rsa. Your public key has been saved in /home/user_name/.ssh/id_rsa.pub. The key fingerprint is: SHA256:ZqXNqWYTWFL1jIEsYjjWhW42q/dY1q2KDhnwKQoxiW8 email@example.com The key's randomart image is: +---[RSA 2048]----+ | o o...oo | |..+ = ..o = | |*. + .... o o | | * .= + = . | |o Eo o. S + | |oo o. + + | |. o. o * . | | ...= o o | | o+.o.. | +----[SHA256]-----+
- Accept all the defaults.
- Press Enter when prompted for a passphrase.
This creates a public key pair for both public and private keys.
The public and private keys are created in the user home directory in a .ssh folder. The public key extension is .pub.
