SSH - ssh-agent

ssh-agent is the authentication agent of the Openssh ssh cli .

It stores un/desencrypted private keys in memory, and communicates with SSH clients via Unix_domain_socket

• Start the ssh-agent in the background.

eval `ssh-agent`
# or ssh-agent bash
# or eval "$(ssh-agent -s)"

Test if SSH agent is running (If nothing is returned, then ssh-agent is not running)

echo "$SSH_AUTH_SOCK"

/tmp/ssh-rfSUL1ldCldQ/agent.1792

• Add SSH private key to the ssh-agent

ssh-add ~/.ssh/id_rsa

ssh-add -l
