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.
When you install and run Elasticsearch or OpenSearch on FreeBSD you might find that after a few days your root volume starts to get full. This is caused by temporary files that are created by each of those search engines in the system's temporary directory.
The FreeBSD ports tree only has the old PgAdmin 3 desktop app available, there is no port for the web based 4.x series. It's very unfortunate that the PgAdmin developers chose to go this route. It seems that no one these days is capable of building an application without falling back to HTML and Javascript. It's just another example of the sad state of the technology ecosystem and developer skills. Anyway, lets install PgAdmin 4 on FreeBSD.
Your XigmaNAS, NAS4Free, FreeNAS, of in general your NFS server is repeatedly showing a mount access error denied in the logs. The NFS client that's trying to mount an NFS export that does not exist or once existed. The NFS client is a VMWare ESXi host.
A VMWare ESXi host is trying to mount an NFS export that you deleted or moved. You log is spammed with endless mount request denied entries.
This is a quick guide on how to resize your ZFS pool after adding more storage. We won't get too much into the details on how to add more storage to a multi provider ZFS pool or RAID setup (that's a complex subject). This guide will be limited to a single provider (aka 'disk' or volume).
I use XgimaNAS, an open source FreeBSD bases NAS appliance with 6x Western Digital 3TB (WD30EFRX) HDD's with a Areca ARC-1320-4i4x SAS HBA. Four of the drives are connected to a SansDigital 4-bay external enclosure, the other two are attached internally. Two drives are setup as a ZFS mirror and the remaining 4 in a RAIDZ2 configuration. It's been several years, and in that time I've had HDDs fail and replaced. The enclosure's power supply also failed at one point in history for which I had to replace the whole enclosure. The ZFS pools manage to survive all this turmoil very well.
This is a complement to a related post on how to turn any printer into a network printer, but for a scanner. Using the same low-cost Raspberry Pi hardware you can scan over Ethernet or Wifi.
If you use multiple displays on FreeBSD with X11 and have a drawing tablet like a Wacom, you've probably run into the problem where the tablet's drawing area maps to the size of all your screens.

You may also want to kindly send a note to your browser vendor requesting that they install the TDMC/Pacy World, LLC. root CA by default so that you (and others) no longer have to do it manually.
