•    Shell

If this command returns any results please remove or stop the application running on that port. I recommend you to use hardware/nsd-dnssec as an authoritative name server with DNSSEC capabilities. NSD is an authoritative only, high performance, simple and open source name server.

caesonia - OpenBSD Email Service

•    Shell

---

By design, email message headers need to be public, for exchanges to happen. The body of the message can be encrypted by the user, if desired. Moreover, there is no way to prevent the host from having access to the virtual machine. Therefore, full disk encryption (at rest) may not be necessary. Given our low memory requirements, and the single-purpose concept of email service, Roundcube or other web-based IMAP email clients should be on a different VPS.

rspamd-influxdb - Metric collector for rspamd webinterface API (InfluxDB Line protocol)

•    Python

---

Quick and dirty approach to get stats of rspamd out of the webinterface's API into InfluxDB for visualizing using Grafana. You may provide the URL and password by defining the path to a configuration file in order to prevent other users from reading the password in clear text from the process list. To do so you need to provide the --config $path argument, e.g.
