Description: Keyboard-interactive events can have multiple steps. Tweak the existing kbd_callback to massage prompts into a format that an end user can handle from python. New public method userauth_keyboardinteractive_callback added to the session class to maintain backwards compatibility. See new example script for usage. I didn't add any new test case since I'm not really sure how it would fit into the existing set-up. To test locally I set spun up a ssh server inside a docker container1 and pointed the example script at it. Below is an example command I used: OTP=$(oathtool --totp -d 6 12345678909876543210) python ./examples/keyboard_interactive_auth.py --host 127.0.0.1 --port 2022 -u sshuser $OTP 552099 hostname Example Dockerfile SSH server with MFA FROM debian:latest RUN apt-get update && apt-get install -y \ openssh-server \ libpam-oath \ oathtool \ && rm -rf /var/lib/apt/lists/* RUN groupadd sshgroup RUN useradd -ms /bin/bash -g sshgroup -p '$1$sshuser$TCmWDAEGpJ.Z.Sj/NN02I.' sshuser RUN echo 'HOTP/T30/6 sshuser - 12345678909876543210' > /etc/users.oath RUN chmod 600 /etc/users.oath RUN echo 'auth required pam_oath.so usersfile=/etc/users.oath window=30 digits=6' >> /etc/pam.d/sshd run cat /etc/pam.d/sshd RUN echo 'ChallengeResponseAuthentication yes \nKbdInteractiveAuthentication yes\n' >> /etc/ssh/sshd_config.d/otp.conf RUN service ssh start EXPOSE 22 CMD ["/usr/sbin/sshd","-D"] Footnotes ↩
