Client configuration
To initialize the client on your Linux system, you should run the following command in your local shell:
$ step ca bootstrap --ca-url=https://sshproxy.hpc.cineca.it --fingerprint 2ae1543202304d3f434bdc1a2c92eff2cd2b02110206ef06317e70c1c1735ecd
ATTENTION: if you have a previous version of smallstep installed and configured on your system, the client will ask if you want to overwrite the existing configuration. To save a copy of a previous version of smallstep installed and configured on your system, make a copy of the directory .step.
If the command run correctly, the prompt will report you the following messages:
The root certificate has been saved in <path-to>/.step/certs/root_ca.crt.
The authority configuration has been saved in <path-to>/.step/config/defaults.json.
Certificate
To use the certificate, the user should activate the ssh-agent running:
$ eval $(ssh-agent)
