The daemon.be servers

Location and connectivity

Historically, Daemon.be servers have been hosted with EV1Servers/RackShack/SoftLayer, SprocketData, Exportal.pl, Hetzner and ait.com. Today, Daemon is spread between Amazon EC2, Google Compute Platform and Hetzner.

Software

Each server runs a version of the 4.x Linux kernel. Internet applications are served by Apache, Dovecot, Postfix, BIND and vsftpd. For webmail we use Roundcube. We use extensive containerization provided by LXC.

Digital certificates are provided by Let's Encrypt. The servers use a variety of security mechanisms, including the Linux auditd subsystem, OSSEC and osquery.

We serve CAA records:
