# Q001-prep.sh — Workstation baseline: SSH key missing
|
|
#
|
|
# Prepares the workstation VM for Q001 "Welcome Aboard".
|
|
# The player's SSH key was never added during provisioning.
|
|
#
|
|
# What this does:
|
|
# - Ensures the player account exists
|
|
# - Removes /home/player/.ssh/authorized_keys (key not provisioned)
|
|
# - Leaves /var/log/auth.log with a "Permission denied (publickey)" entry
|
|
#
|
|
# Idempotent: safe to run multiple times.
|
|
# AGENT RULES: Never run against a live player session.
