Better SSH Authorized Keys Management

A seemingly common problem that people encounter is how to handle all of your users authorized_keys file.

People struggle over management, ensuring that users only have specific keys in the authorized_keys file or even a method for expiring keys. A centralized key management system could help provide all of this functionality with a little scripting.

One piece of functionality overlooked in OpenSSH is the AuthorizedKeysCommand configuration keyword. This configuration allows you to specify a command that will run during login to retrieve a users public key file from a remote source and perform validation just as if the authorized_keys file was local.

Here is an example directory structure for a set of users with SSH public keys that can be shared out via a web server:

Wordpress plugin to retry failed emails

When using Wordpress wp_mail() function, there is no easy way to schedule retries, when the email fails to be sent.
There is probably a few plugins available that could handle this, but I didn't find any that would just do that.
And so, I decided to code it myself.

Of note: I added this code to a custom (unpublished) plugin I maintain. If you don't have your own plugin to add this to, either Google how to create your own Wordpress plugin, or use one of the numerous available plugins that allows you to inject (PHP) code in your Wordpress installation. As a last resort, you could add this code in your functions.php
