 [This](https://ettore.dreucci.it) website is powered by [Hugo](https://gohugo.io/), an open-source static website generator written in [Go](https://golang.org/). I can write pages and posts in [Markdown](https://daringfireball.net/projects/markdown/) and then generate some static .html pages to upload to a webserver.

 If you manage your DNS server(s) with ISPConfig you may want a *dynamic entry* that gets updated automatically every time the target host changes its IP address.

 [ISPConfig](https://www.ispconfig.org/) comes with [jailkit](https://olivier.sessink.nl/jailkit/) enabled so that the “clients” that login via ssh are limited to a chroot shell with only some specific command. **Every client website has its own jailkit.**
