FreeBSD

There is a serious lack of basic documentation on how to use Apache Solr on FreeBSD. Lets change that.

The FreeBSD Handbook has a great guide on how to create a classic jail.  I refer to it all the time, but with a slight change so that it's more opinionated in the way it's configured and operates.

This is an update to the original How to Setup DomainKeys Identified Mail (DKIM) with Postfix and FreeBSD. A lot has changed in the time since that was written. First off, it's no longer called DomainsKeys. Now a days the standard goes by DKIM and the software used is OpenDKIM.

If you are getting errors like HttpRequestBase not present or unable to resolve class groovyx.net.http.HTTPBuilder on your Jenkins jobs then you will need to manually download and install some missing libraries.

Normally when you want to set options for your SSH server you would edit it's default configuration file located under /etc/ssh/sshd_config. This is the default file that's read by the sshd application. However this becomes a little more challenging when you want to use automated tooling to roll out configuration changes.
