This document summarizes the interactions between the Docker client and the Docker Hub during push and pull commands through version 1 of the registry API. It was compiled to aid in writing a compatible registry server implementation after the existing API documentation proved occasionally incomplete or inaccurate.

In a two-part post I'm going to show you some tricks you can do with SSH logins. This post covers setting up two-factor SSH authentication with the Google Authenticator app.
I was recently getting some servers in shape so I can pass the Payment Card Industry standards questionnaire and one requirement was two-factor authentication access to the server. I queried whether SSH key + passphrase was acceptable but didn't get a clear answer so I figured I'd explore setting up another authentication factor myself, plus it piqued my interest.
After a bit of research I found it was possible using a PAM module but it doesn't work along with SSH key authentication (only password authentication) and I only use SSH key logins for my servers.
