Today is the day after BSDCan 2019. The power cables and extension cords from the hacking lounge have been laid to rest in an Ottawa basement until next year. Sitting in my parents garden, I noticed some Nagios cert warnings: I logged into my certificates server (the website from which all my hosts download their […]
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:

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

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

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

This post has been replaced by a newer post. This is the previous post for this system configuration. For future reference, this is the knew server … oh wait, I think it’s this server which is was mounted in the 3U chassis mentioned in this post (perviously erroneously referred to as a 4U). It runs
This server, knew has had an intermittent problem related to CAM status: SCSI Status Error messages. There is a FreeBSD Forums post about it. On Sunday, the problem returned, and this time it degraded the zpool. I collected the information in this gist and I will list the relevant portions below. I had enabled smartd

On Monday night at about 5:30 PM, I noticed the email: ** PROBLEM alert – knew/zpool is CRITICAL ** What sickened me was that the email was sent at 3:58 PM. That makes me think I should add a Pushover.net alert …. I could do that at my mail server. Logging into the server, I
