Setup the ssh server and ssh keys - - The ssh key should not be protected by a password, or it will prompt for it every time. - Create the key on the client: - - .. code:: bash - - ssh-keygen -t rsa -f foo.rsa - - Then copy foo.rsa.pub to the remote machine (user@kiunix:/home/user/.ssh/authorized_keys), - and make sure the permissions are correct (chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys) - - A separate key for the build processes can be set in the environment variable WAF_SSH_KEY. - The tool will then use 'ssh-keyscan' to avoid prompting for remote hosts, so - be warned to use this feature on internal networks only (MITM). - - .. code:: bash - - export WAF_SSH_KEY=~/foo.rsa - -5.
