I’ve been making use of some FreeBSD-provided scripts within my Nagios monitoring. Recently, I started seeing a problem after some jail maintenance. This post is about that problem and the fix. Full disclosure: the issue was not what I thought it was and I did not solve it. I’m using: FreeBSD 11.2-RELEASE-p9 The scripts are: […]

ZFS is very flexible about mountpoints, and there are many features available to provide great flexibility. When you create your second zpool this is what it might look like: $$ zfs list -r main_tank NAME USED AVAIL REFER MOUNTPOINT main_tank 893G 3.52T 96K /main_tank main_tank/data 786G 3.52T 88K /main_tank/data main_tank/data/dvl 755G 3.52T 755G /main_tank/data/dvl main_tank/data/freshports

I have been using ezjail since at least 2008 (see earlier blog post). A few years ago, I started deploying iocage on new servers. About three months ago, I starting converting systems from ezjail to iocage. When I converted my first system, I found that the existing documentation for conversion was incomplete. Specifically, symlinks were

We know the routine. You have a desktop, and a laptop, or perhaps two laptops. You want your files in both places. A shared, remotely mounted directory is not ideal. Instead, let’s have the systems synchronize themselves. That’s where syncthing comes in: Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized.

I started playing with /usr/local/etc/periodic/security/405.pkg-base-audit as part of a monitoring system. It works fine from the command line, but when I use Nagios plugins, I am getting unexpected results. By unexpected, I mean messages about FreeBSD 10.2. The host in question runs FreeBSD 12.0. The problem cannot be reproduced on the host, only from the

I noticed some double timestamps in my logs recently. They started just after I upgraded the host to FreeBSD 12, but I am not convinced they are related. This is from /var/log/messsages: Jan 22 21:41:40 knew 1 2019-01-22T21:41:40.760533+00:00 knew.int.unixathome.org pkg 89351 – – py36-iocage-devel upgraded: 1.0.0.20181219,1 -> 1.0.0.20190122,1 They started late yesterday, this is from

Today I will upgrade knew from FreeBSD 11.2 to FreeBSD 12.0. It so happens that this is my last server at home which is still running 11.2, but I do have another server still on 11.2, but that one is at NYI. This post isn’t so much about beadm or about freebsd-update. I have written

I use bind (Berkeley Internet Name Domain) as my DNS server. I am currently running bind 9.11.5P1 on FreeBSD 11.2-RELEASE-p8 in a jail, with iocage as my jail manager. The OS, jail, and jail manager should play no part in how this works. I have been collecting statistics from bind for some time. I have

This post might help me in configuring net-snmp to deliver Nginx statistics to LibreNMS. As such, this post may not be as helpful to you as the official documentation. Key is this URL: http://127.0.0.1/nginx-status The nginx.conf file needs something like this: NOTE: the fastcgi_pass line might also be fastcgi_pass 10.80.0.92:9000 depending on what you find

Current FreeBSD versions will allow you to create a zroot zpool from which you can boot. However, when I created the main zpool for slocum (on Fri May 3 2:16 2013), that option did not exist. You might ask: how do I know that date? [dan@slocum:~] $ zfs get creation system NAME PROPERTY VALUE SOURCE
