Using Let’s Encrypt and Certbot to automate the creation of certificates for OpenVPN

Recently at Planet 9 Energy, I had to setup a VPN access to secure some of our internal services. One of the requirements was to make the provisioning easy to reproduce over multiple environments, so we ended up playing a bit with Terraform, while obviously adopting OpenVPN for the VPN server. Another important requirement was to expose the OpenVPN web interface (also called Access Server) using an SSL, which I was expecting to be one of the most challenging things to automate, instead, it turned out to be…

8 invitations to try Keybase.io

Note that I am assuming you are using Ubuntu or some other Debian derivate. Otherwise the commands may change a bit (but not to much I believe). 1. Stop the mysql daemon 2. Disable the security checks The mysqld_safe command will essentially…

Symfony security: authentication made simple (well, maybe!)

The Symfony2 security component has the fame of being one of the most complex in the framework. I tend to believe that’s partially true, not because the component is really that complex, but because there are (really) a lot of concepts involved and it may be difficult to understand them all at once and have a clear vision as a whole.
