Obtaining and Using an SSL Certificate Using Let's Encrypt

3 minute read Published:

We’ll be using Let’s Encrypt in order to obtain and use - in a web server, for example - an SSL certificate for our domain.

Let’s Encrypt is a free, automated, and open certificate authority brought to you by the non-profit Internet Security Research Group (ISRG).

This will be done through certbot. Setting it up is as trivial as cloning the Git repository and running the certbot-auto file. Initial set-up1 is left as an exercise for the reader.

Remounting a Read-Only Partition With a Faulty Fstab in Ubuntu/Debian

2 minute read Published:

The filesystem table, or more commonly known as fstab or /etc/fstab, is a system configuration file, which is parsed by mount during boot, and misconfiguration or typos can render the system somewhat unusable.

By default on Debian and Ubuntu systems, the root partition has the errors=remount-ro option set, which indicates that if the mount encounters any error, it should only remount the partition as read-only, to prevent damage. In that case, for example, many applications will stop working, unexpected behaviour will be present, among other issues.
