Which environment variables are used by ssh-agent? (Please select TWO variables)
A.
SSH_AGENT_KEY
B.
SSH_AGENT_SOCK
C.
SSH_AGENT_PID
D.
SSH_AUTH_SOCK
E.
SSH_AUTH_PID
Explanation:
A unix-domain socket is created and the name of this socket is stored in the SSH_AUTH_SOCK environment variable.
The socket is made accessible only to the current user.
This method is easily abused by root or another instance of the same user.
The SSH_AGENT_PID environment variable holds the agent’s process ID.
The agent exits automatically when the command given on the command line terminates.Ref: http://www.cl.cam.ac.uk/cgi-bin/manpage?ssh-agent
right answer should be C and D: (man ssh-agent)
