I manage FreeBSD- and Debian-based systems.
All of my websites are hosted using Nginx.
- All of them are secured with TLS using Let's Encrypt certificates managed with certbot.
I self-host my email server with Postfix and Dovecot. I do not trust anyone but myself with email hosting as too many websites rely on them for password resets.
All of my servers are connected with each other with OpenVPN. This adds an extra layer of security and makes it safe to transmit data without additional encryption (e.g.
zfs send tank | nc 172.16.1.42 1337).
All of my work on Github and other git hosting services is mirrored to a personal Gitea server. Some of the tools I created are also exclusively available on my instance.
All data is stored on ZFS, which makes it trivial to backup, mirror and encrypt data. It also ensures data will never become corrupt.
I host some other services too, such as an Yggdrasil node.
