Last week’s TechMail was Two-factor SSH authentication via Google secures Linux logins which talks about using Google two-factor authentication with SSH (and PAM in general).

It talks about generating keys, using ssh-copy-id to copy keys to servers, and using hashed representations of host keys to obscure what machines you connect to in case someone(…)

I use this quite a bit with remotely-deployed pfSense boxen to configure it using the web interface and it works great. Of course, the(…)
