Two-factor SSH authentication via Google secures Linux logins
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).

Secure remote firewall administration via SSH
This week’s TechMail is Secure remote firewall administration via SSH which talks about using ssh to create a secure tunnel to a remote network/system to use with configuring a remote firewall.
