Onefuzz enables automatically connecting to fuzzing & crash repro nodes via SSH. Each VM and VM scale set has its own SSH key pair.
On Linux VMs, the public key is written to ~onefuzz/.ssh/authorized_keys
For Windows VMs, the public key is written to
\$env:ProgramData\ssh\administrators_authorized_keys following
Windows OpenSSH server guides.
When using any of the SSH enabled components of the onefuzz CLI, the CLI will automatically fetch the key-pair for a VM as needed. The private key is written to a temporary directory and removed upon completion of the SSH command.
NOTE: As VMs and VM scale sets are intended to be short-lived and ephemeral, the onefuzz CLI configures SSH to not write to the user's known host file and ignores host key checking.
